It is clear the OP doesn't want to give me any serious answer.... So just feel free to burn brain cycles on somebody like that.

This is a UDF to handle the AutoIt Error msgbox when our awesome code goes I've been using trancexx's code for the longest time and since I iron some wrinkles in my ( personal use ) UDF, decided to organize it in a dignifying way and post it. The ZIP with the code is in the downloads area. I'm posting this because most other handlers use /ErrorStdOut to catch errors and they are not that common, for us great coders So makes little sense to me to run 2 EXEs for something unlikely to happen. No one made a UDF of this, so, I did. oh, ..there are things where this will be of no use, say, infinite recursion or what not, so, if the the AutoIt Error msgbox was to popup then this UDF should do it. ...let me know if you liked it, or post your views to better it. Cheers There is also an EventViewer_GetMyEntries() down this post that may come in handy.

IE is not new but newer versions are not emulated ( IE8+ ) so a function to expressly set the IE version to load when embedded was needed.

Your ideas are very much welcomed. PS: for now I guess this code is just an example. 6/27/2020 update: To look for the IE version and use that as the Default value. This way if you have, say v10.x.x.x, it will not try to emulate v11. The default browser value is the Int(version) & "000", so it does not need a lookup a table. Tested on XP, Win7 and Win10. 6/28/2020 update: Renamed the functions from *BrowserEmulation() to * EmbeddedBrowserEmulation() as it truly only applies to an Embedded Browser. Also changed the Version discovery form looking at the EXE to looking at the DLL. ( all this thanks to @Chimp's clues )

Well, I didn't feel old until just now. Thanks

Thank you so much. Based on my searches, I was expecting something more complicated. I am trying to create it now.

I've updated it a bit, Here is the code if you prefer a slider input for AutoIT (makes it more fun). Note the Arduino code doesn't change here, use the same code as in the above post. AutoIT code: #include <CommMG.au3> #include <ButtonConstants.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <EditConstants.au3> #include <StaticConstants.au3> Global $CMPort = 7 Global $CmBoBaud = 9600 Global $sportSetError = '' Global $CmboDataBits = 8 Global $CmBoParity = "none" Global $CmBoStop = 1 Global $setflow = 2 _CommSetPort($CMPort, $sportSetError, $CmBoBaud, $CmboDataBits, $CmBoParity, $CmBoStop, $setflow) If @error Then MsgBox(16,"Error!","Can't connect to Arduino on port - "&$CMPort) Exit EndIf _CommSetRTS(0) _CommSetDTR(0) #Region ### START Koda GUI section ### Form= Global $Form1_1 = GUICreate("AutoIT -->Arduino Servo Mover", 796, 116, 204, 185) Global $ServoLabel = GUICtrlCreateLabel("Move slider to move servo", 280, 16, 226, 28) GUICtrlSetFont(-1, 14, 400, 0, "MS Sans Serif") Global $Slider1 = GUICtrlCreateSlider(130, 56, 526, 45) GUICtrlSetLimit($Slider1, 180, 0) GUICtrlSetData($Slider1, 90) GUISetState(@SW_SHOW) #EndRegion ### END Koda GUI section ### While 1 $nMsg = GUIGetMsg() $ServoSliderOutput = GUICtrlRead($Slider1) _CommSendString(stringformat("A%03d",int($ServoSliderOutput))) Sleep(20) Switch $nMsg Case $GUI_EVENT_CLOSE Exit EndSwitch WEnd

Found a way, still I tend to believe it might be a bug. But anyway, I have found a way not too complicated : #include <GUIConstants.au3> #include <WinAPI.au3> #include <Array.au3> Global $aFileList $hGUI = GUICreate("Form2", 565, 247, -1, -1, -1, $WS_EX_WINDOWEDGE) $Input1 = GUICtrlCreateInput("", 32, 16, 505, 121, -1, $WS_EX_ACCEPTFILES) ; Now only here the drop sign appears GUICtrlSetState(-1, $GUI_DROPACCEPTED) Global $idDummy = GUICtrlCreateDummy() GUISetState() $wProcHandle = DllCallbackRegister("_WindowProc", "ptr", "hwnd;uint;wparam;lparam") $wProcOld = _WinAPI_SetWindowLong(GUICtrlGetHandle($Input1), $GWL_WNDPROC, DllCallbackGetPtr($wProcHandle)) While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $GUI_EVENT_DROPPED ; Not triggered, I think it should be considered as a bug ConsoleWrite(@GUI_DragFile & @CRLF) Case $Input1 ConsoleWrite("input1" & @CRLF) Case $idDummy For $i = 1 To $aFileList[0] ConsoleWrite($aFileList[$i] & @CRLF) Next GUICtrlSetData ($Input1, _ArrayToString ($aFileList,"|",1)) EndSwitch WEnd GUIDelete($hGUI) DllCallbackFree($wProcHandle) Func _WindowProc($hWnd, $Msg, $wParam, $lParam) Switch $hWnd Case GUICtrlGetHandle($Input1) Switch $Msg Case $WM_DROPFILES $aFileList = _WinAPI_DragQueryFileEx($wParam) If Not @error Then GUICtrlSendToDummy($idDummy) _WinAPI_DragFinish($wParam) Return 0 EndSwitch EndSwitch Return _WinAPI_CallWindowProc($wProcOld, $hWnd, $Msg, $wParam, $lParam) EndFunc ;==>_WindowProc Needs some cleanup but you will get the idea...

I'd like to give a token of my appreciation, but I see you already have many. But still, if you ever run out, you know where you can find me. By the way ......... good work ......... keep it up ......... for science.

Hello again, I apologize for the delay, life got in the way again... as it always does Today I made some good progress, I redesigned my code to handle one token at a time, instead of all tokens at once, this has made things simpler. I now have a tangible scanner framework, and I have added support for quite a few types of tokens! enum TokenType { TOK_UNKNOWN, TOK_WHITESPACE, TOK_COMMENT, TOK_DIRECTIVE, TOK_NUMBER, TOK_WORD, TOK_OPERATOR, TOK_BRACKET, TOK_COMMA, }; I still have to add support for macros, variables, strings etc. but that shouldn't be very hard. I also forgot to mention that handling multi-line comments turns out to be not as simple as I thought, it requires special handling and it has unique behavior, I believe it is the only multi-line (pre-processor) directive.

The next step would be actually analyzing the tokens and constructing a source tree from it (syntactic analysis is the buzz word)

I'm not everyone, but I wish you luck bud anyway ... get those juices flowing, climb those mountains, leap those hurdles, get down & dirty ... and most importantly have a beer believe in yourself.

An obvious use of ROT objects is in connection with tasks such as inter-process communication (IPC). The advantage of using ROT objects for these tasks is partly that you can handle large amounts of data and partly that you can handle the vast majority of AutoIt data types. This thread implements a UDF for inter-process communication between two AutoIt scripts based on ROT objects. Simple exampleExamples\0) Sample\ is a simple example. There are 4 files in the folder: Sender.au3: #include "..\..\Includes\IPCROT_Sender.au3" Example() Func Example() ; Create array Local $aArray[1000][10] For $i = 0 To 1000 - 1 For $j = 0 To 9 $aArray[$i][$j] = $i & "/" & $j Next Next ; Send array IPCROT_Sender( "Example", $aArray ) MsgBox( 0, "Sender", "@error = " & @error & ", @extended = " & @extended & @CRLF ) $aArray = 0 EndFunc Receiver.au3: #include <Array.au3> #include "..\..\Includes\IPCROT_Receiver.au3" Example() Func Example() ; Get array Local $aArray IPCROT_Receiver( "Example", $aArray ) MsgBox( 0, "Receiver", "@error = " & @error & ", @extended = " & @extended & @CRLF ) _ArrayDisplay( $aArray, "Receiver" ) $aArray = 0 EndFunc Start1.au3: Run( @AutoItExe & " /AutoIt3ExecuteScript Sender.au3", "" ) Run( @AutoItExe & " /AutoIt3ExecuteScript Receiver.au3", "" ) Start2.au3: Run( @AutoItExe & " /AutoIt3ExecuteScript Receiver.au3", "" ) Run( @AutoItExe & " /AutoIt3ExecuteScript Sender.au3", "" ) Start1.au3 and Start2.au3 shows that it doesn't matter if you start Sender.au3 first or Receiver.au3 first. Another way to start the programs is to double-click Receiver.au3 and then double-click Sender.au3 within 10 seconds. Or double-click Sender.au3 and then double-click Receiver.au3 within 10 seconds. 10 seconds because the default timeout for both IPCROT_Sender() and IPCROT_Receiver() functions is 10 seconds. Timeout can be set via a parameter. Debug exampleExamples\1) Debug\ is a debug example. There are 3 files in the folder: Sender.au3: #include "..\..\Includes\IPCROT_SenderDebug.au3" Example() Func Example() ; Create array Local $aArray[1000][10] For $i = 0 To 1000 - 1 For $j = 0 To 9 $aArray[$i][$j] = $i & "/" & $j Next Next ; Send array Local $hDebug IPCROT_Sender( $hDebug, "Debug", $aArray ) MsgBox( 0, "Sender", "@error = " & @error & ", @extended = " & @extended & @CRLF ) EndFunc Receiver.au3: #include <Array.au3> #include "..\..\Includes\IPCROT_ReceiverDebug.au3" Example() Func Example() ; Get array Local $aArray, $hDebug IPCROT_Receiver( $hDebug, "Debug", $aArray ) MsgBox( 0, "Receiver", "@error = " & @error & ", @extended = " & @extended & @CRLF ) _ArrayDisplay( $aArray, "Receiver" ) $aArray = 0 EndFunc Start.au3: Run( @AutoItExe & " /AutoIt3ExecuteScript Sender.au3", "" ) Run( @AutoItExe & " /AutoIt3ExecuteScript Receiver.au3", "" ) The difference between the debug and non-debug versions is the include files and the way the IPCROT_Sender() and IPCROT_Receiver() functions are called. The debug functions must be called with an initial $hDebug parameter that is a reference to the debug window. The Debug window contains an Edit control to display debug information. If you run Start.au3, debug information is generated in this way: Sender Debug output: Establish communication with Receiver() function Info - Check that the (hidden) window "DebugIPCROT_SenderGui" doesn't exist Checking... Info - The (hidden) window "DebugIPCROT_SenderGui" doesn't exist Checked OK Info - Create window to establish communication between Sender and Receiver Creating...

It's the MsgBoxes that keeps the debug windows open. When you close the Receiver MsgBox, the array received from the Sender() function is displayed with _ArrayDisplay(). Now, the _ArrayDisplay() function keeps the Receiver debug window open. When you close the _ArrayDisplay() window, the Receiver debug window also closes. When you close the Sender() MsgBox, the Sender debug window also closes. If you double-click Sender.au3 and wait for 10 seconds until timeout, you'll see this information.

The code in both the IPCROT_Sender() and IPCROT_Receiver() functions is divided into two sections. The first section is about establishing communication with the other function. The second section is about the actual data transfer. Function header for IPCROT_Sender(): ; Success: Returns 1 ; Failure: Returns 0 ; Sets @error and @extended ; @error = 1: SenderGui error ; @error = 2: $hReceiverGui error ; @error = 3: Communication with Receiver cannot be verified ; @error = 4: ROT_RegisterObject error ; @error = 5: IPCROT_SendCopyData error ; @error = 6: Get the ROT object error ; @error = 7: Data is ready message error ; @error = 8: Error occured in Receiver() function ; @error = 9: Idle loop timeout, most likely an error ; @extended = zero based error occurrence Func IPCROT_Sender( _ ; Pass data (usually an array or object) from Sender to Receiver through ROT object. $sNameId, _ ; $sNameId is a unique identifier to secure multiple concurrent data communications. $vData, _ ; $vData is the data to be sent from Sender to Receiver, usually an array or object. $iTimeOut = 10 ) ; Time window to establish communication between Sender() and Receiver() functions. ; Does not include time for the actual data transfer. Time setting in seconds. Function header for IPCROT_Receiver(): ; Success: Returns 1 ; Failure: Returns 0 ; Sets @error and @extended ; @error = 1: ReceiverGui error ; @error = 2: $hSenderGui error ; @error = 3: Communication with Sender cannot be verified ; @error = 4: Error occured in Sender() function ; @error = 5: Get the ROT object error ; @error = 6: Idle loop timeout, most likely an error ; @extended = zero based error occurrence Func IPCROT_Receiver( _ ; Pass data (usually an array or object) from Sender to Receiver through ROT object. $sNameId, _ ; $sNameId is a unique identifier to secure multiple concurrent data communications. ByRef $vData, _ ; $vData is the data to be sent from Sender to Receiver, usually an array or object. $iTimeOut = 10 ) ; Time window to establish communication between Sender() and Receiver() functions. ; Does not include time for the actual data transfer. Time setting in seconds. Note that the debug versions of the functions have an additional $hDebug parameter as the first parameter. It's a reference to the debug window. Establish communication Sender-Receiver communication is established through simple Window automation. IPCROT_Sender() creates a (hidden) window titled $sNameId & "IPCROT_SenderGui". IPCROT_Receiver() creates a (hidden) window titled $sNameId & "IPCROT_ReceiverGui". The other function establishes communication by identifying this window. To establish communication between multiple Sender-Receiver pairs at once, $sNameId must be unique for each Sender-Receiver pair. And both the Sender and Receiver window must be opened within the timeout period. Data transfer When communication is established, it's the Sender who plays the role of server. Sender creates the ROT object, sends $sROTNameId to Receiver via a WM_COPYDATA message, stores data in the ROT object and sends a "Data is ready message" to the Receiver. $sROTNameId is created uniquely in this way: $sROTNameId = $sNameId & ROT_CreateGUID(). The Receiver plays the role of client. Once the Receiver has received the "Data is ready message", the Receiver accesses the ROT object with ObjGet() and retrieves the data. Receiver informs Sender that data has been received, which terminates the communication. Internal communication Information in the form of integers sent via WM_USER messages controls the internal communication between Sender and Receiver.

The example is based on the example for the VarGetType() function in the help file. DataTypes.au3 is a slightly modified version of this example. Note that all remaining examples run in debug mode so it's possible to see what's going on. In Sender.au3, the various data types are stored in a dictionary object and sent in this way: Local $oDict = ObjCreate( "Scripting.Dictionary" ) $oDict( "$aArray" ) = $aArray $oDict( "$dBinary" ) = $dBinary $oDict( "$bBoolean" ) = $bBoolean $oDict( "$pPtr" ) = $pPtr $oDict( "$hWnd" ) = $hWnd $oDict( "$iInt" ) = $iInt $oDict( "$fFloat" ) = $fFloat $oDict( "$oObject" ) = $oObject $oDict( "$sString" ) = $sString $oDict( "$tStruct" ) = $tStruct $oDict( "$vKeyword" ) = $vKeyword $oDict( "$fuMsgBox" ) = $fuMsgBox $oDict( "$fuFunc" ) = $fuFunc $oDict( "$fuUserFunc" ) = $fuUserFunc ; Send $oDict Local $hDebug IPCROT_Sender( $hDebug, "DataTypes", $oDict ) Receiver.au3: #include "..\..\Includes\IPCROT_ReceiverDebug.au3" Example() Func Example() ; Get $oDict Local $oDict, $hDebug IPCROT_Receiver( $hDebug, "DataTypes", $oDict ) MsgBox( 0, "Receiver: Variable Types", _ "$aArray : " & @TAB & @TAB & VarGetType( $oDict( "$aArray" ) ) & " variable type." & @CRLF & _ "$dBinary : " & @TAB & @TAB & VarGetType( $oDict( "$dBinary" ) ) & " variable type." & @CRLF & _ "$bBoolean : " & @TAB & VarGetType( $oDict( "$bBoolean" ) ) & " variable type." & @CRLF & _ "$pPtr : " & @TAB & @TAB & VarGetType( $oDict( "$pPtr" ) ) & " variable type." & @CRLF & _ "$hWnd : " & @TAB & @TAB & VarGetType( $oDict( "$hWnd" ) ) & " variable type." & @CRLF & _ "$iInt : " & @TAB & @TAB & VarGetType( $oDict( "$iInt" ) ) & " variable type." & @CRLF & _ "$fFloat : " & @TAB & @TAB & VarGetType( $oDict( "$fFloat" ) ) & " variable type." & @CRLF & _ "$oObject : " & @TAB & VarGetType( $oDict( "$oObject" ) ) & " variable type." & @CRLF & _ "$sString : " & @TAB & @TAB & VarGetType( $oDict( "$sString" ) ) & " variable type." & @CRLF & _ "$tStruct : " & @TAB & @TAB & "Not recognized as a valid variable type." & @CRLF & _ "$vKeyword : " & @TAB & VarGetType( $oDict( "$vKeyword" ) ) & " variable type." & @CRLF & _ "fuMsgBox : " & @TAB & "Not recognized as a valid variable type." & @CRLF & _ "$fuFunc : " & @TAB & @TAB & "Not recognized as a valid variable type." & @CRLF & _ "$fuUserFunc : " & @TAB & "Not recognized as a valid variable type." ) EndFunc And this is the text in the Receiver MsgBox: $aArray : Array variable type. $dBinary : Binary variable type. $bBoolean : Bool variable type. $pPtr : Int32 variable type. $hWnd : Int32 variable type. $iInt : Int32 variable type. $fFloat : Double variable type. $oObject : Object variable type. $sString : String variable type. $tStruct : Not recognized as a valid variable type. $vKeyword : Keyword variable type. fuMsgBox : Not recognized as a valid variable type. $fuFunc : Not recognized as a valid variable type. $fuUserFunc : Not recognized as a valid variable type. Only the $tStruct and the function data types are not received correctly by the Receiver function. The Int32 types for $pPtr and $hWnd can easily be converted to pointer and window handles with the Ptr() and HWnd() functions. DllStructThe DllStruct data type ($tStruct in the example above) isn't a COM compatible data type and is therefore not received correctly by the Receiver function. But the Binary data type is received correctly. One way to handle the DllStruct is to convert it to a Binary before it's sent by the Sender() function. And then convert the Binary back to a DllStruct after it's received by the Receiver() function. Examples\3) DllStruct\ is about the DllStruct data type. Binary data What is Binary data and how is Binary data stored in internal AutoIt code? in Accessing AutoIt Variables in Tests\Examples\1) Simple variables\Example3.au3 all the data types in the example for the VarGetType() function are examined. This is the result for the Binary data type: $dBinary Type = Binary ptr = 0x009C59A0 ($pVariant) vt = 0x2011 (VT_ARRAY+VT_UI1, array of 1 byte unsigned integers) data = 0x009DABF8 This means that Binary data is stored internally as a safearray of bytes (also known as a bytearray). When Binary data is passed to a COM method as a parameter, the pointer to this safearray is passed in a variant. Sender and Receiver Sender.au3: #include "AccVars.au3" #include "..\..\Includes\IPCROT_SenderDebug.au3" Example() Func Example() Local Const $tagStruct = "struct;int var1;byte var2;uint var3;char var4[128];endstruct" Local $tStruct1 = DllStructCreate( $tagStruct ) DllStructSetData( $tStruct1, "var1", -1 ) DllStructSetData( $tStruct1, "var2", 255 ) DllStructSetData( $tStruct1, "var3", -1 ) ; The -1 (signed int) will be typecasted to unsigned int.

AccVars_DllStructToBinary() converts the DllStruct to Binary using the techniques from Accessing AutoIt Variables. The function is discussed below. $tagStruct and $dBinary are stored in a dictionary object and sent using the Sender() function. The original data in $tStruct1 looks like this in a MsgBox: Struct Size: 140 Struct pointer: 0x00B64EA8 Data: -1 255 4294967295 hello Receiver.au3: #include "..\..\Includes\IPCROT_ReceiverDebug.au3" Example() Func Example() ; Get $oDict Local $oDict, $hDebug IPCROT_Receiver( $hDebug, "DllStruct", $oDict ) Local $iError = @error, $iExtended = @extended If $iError Then MsgBox( 0, "Receiver", "@error = " & $iError & ", @extended = " & $iExtended & @CRLF ) Return EndIf Local $tagStruct = $oDict( "$tagStruct" ) Local $dBinary = $oDict( "$dBinary" ) ; Convert Binary to DllStruct Local $iSize = BinaryLen( $dBinary ) Local $tBytes = DllStructCreate( "byte[" & $iSize & "]" ) DllStructSetData( $tBytes, 1, $dBinary ) Local $tStruct2 = DllStructCreate( $tagStruct, DllStructGetPtr( $tBytes ) ) MsgBox( 0, "Receiver: $tStruct2", _ "Struct Size: " & DllStructGetSize( $tStruct2 ) & @CRLF & _ "Struct pointer: " & DllStructGetPtr( $tStruct2 ) & @CRLF & _ "Data:" & @CRLF & _ " " & DllStructGetData( $tStruct2, "var1" ) & @CRLF & _ " " & DllStructGetData( $tStruct2, "var2" ) & @CRLF & _ " " & DllStructGetData( $tStruct2, "var3" ) & @CRLF & _ " " & DllStructGetData( $tStruct2, "var4" ) ) EndFunc The dictionary object is received by the Receiver() function and $tagStruct and $dBinary are extracted.

The function is used to convert a DllStruct to Binary.

The whole purpose of using the techniques of Accessing AutoIt Variables is to exploit the internal COM conversions implemented in compiled C/C++ code to do all the hard work. Alternatively, it's possible to make the same conversions in a loop in (slow) interpreted AutoIt code. The Variant and Safearray UDFs are copied directly from Variants and Safearrays. Large array In Examples\4) Large array\, an array of 250,000 rows and 10 columns is created and sent from Sender to Receiver. In the debug windows you can see how long each sub-task takes. At the Receiver, the array is displayed in a virtual ArrayDisplay. The array is created with the functions of Fast Array Sorting and Management Functions UDF. Although this example is mostly about compiled code, most functions are also implemented in pure AutoIt code. One of these functions, FAS_Random2DArrayAu3(), is used to create the array. The function is found in Examples\Data Display\Resources\. A few code lines have been added to generate progress bar information. Examples\8) Two concurrent data transfers\ is also about large arrays. Other examples5) Array of arrays\ and 6) Array of objects\ is about arrays with embedded data. You can also create an array of embedded DllStructs. But then the DllStructs must be converted to Binary before the array is sent from Sender to Receiver. Arrays in the examples are 1D and 2D arrays. But it can also be 3D and 4D arrays. All valid AutoIt arrays are likely to work. 7) Two way data transfer\ demonstrates how to implement two-way data transfer. 7z-fileThe 7z-file contains source code for the UDF and examples. You need AutoIt 3.3.12 or later. Tested on Windows 7 and Windows 10. Comments are welcome. Let me know if there are any issues. IPCviaROTobjects.7z

UsageAn obvious use of ROT objects is in connection with tasks such as inter-process communication (IPC) and job processing. The advantage of using ROT objects for these tasks is partly that you can handle large amounts of data and partly that you can handle the vast majority of AutoIt data types. Using a ROT object it's very easy to transfer arrays between two different processes. At the same time, the internal data types of the array elements are preserved. If an array containing integers, floats, and strings is passed from a sender to a recipient, then it's still integers, floats, and strings at the recipient. This means that the recipient can sort the array with exactly the same result as a sort of the array at the sender. Not just simple data types are preserved. If an array element contains another array (embedded array) or an object (embedded object), then this embedded array or object is still valid at the recipient. ROT objects are based on COM techniques. How is it possible that proprietary AutoIt data types such as arrays, can be transferred between a sender process and a receiver process using a technique based on standard COM data types? This is possible because the AutoIt array is converted to a safearray of variants (default COM array) at the sender and converted back to an AutoIt array at the receiver. But en route between sender and recipient it's a safearray. These conversions are performed automatically by internal AutoIt code (compiled C/C++ code, very fast). If you are interested you can find more information on these topics in Accessing AutoIt Variables. Passing array between AutoIt programsExamples\2) IPC Demo\Array\ contains two files that very simply demonstrate the exchange of arrays between programs running in two different processes. The example is a copy of the example in this thread but implemented with the new IRunningObjectTable UDF. 1) Server.au3: #include <Array.au3> #include "..\..\..\Includes\IRunningObjectTable.au3" Example() Func Example() MsgBox( 0, "Server", "This is server" ) Local $sDataTransferObject = "DataTransferObject" & ROT_CreateGUID() ROT_RegisterObject( Default, $sDataTransferObject ) ; Default => Object = Dictionary object Local $oDataTransferObject = ObjGet( $sDataTransferObject ) ; Dictionary object ; Create array Local $aArray[1000][10] For $i = 0 To 1000 - 1 For $j = 0 To 9 $aArray[$i][$j] = $i & "/" & $j Next Next _ArrayDisplay( $aArray, "Array on server" ) ; Transfer data $oDataTransferObject.Add( "$aArray", $aArray ) ; Start client RunWait( @AutoItExe & " /AutoIt3ExecuteScript " & '"2) Client.au3" ' & $sDataTransferObject ) ; ------- Server waiting while client is executing ------- MsgBox( 0, "Server", "This is server again" ) ; Receive data on server $aArray = $oDataTransferObject.Item( "$aArray" ) _ArrayDisplay( $aArray, "Modified array on server" ) EndFunc 2) Client.au3: #include <Array.au3> Example() Func Example() MsgBox( 0, "Client", "This is client" ) ; Data transfer object Local $sDataTransferObject = $CmdLine[1] Local $oDataTransferObject = ObjGet( $sDataTransferObject ) ; Receive data on client Local $aArray = $oDataTransferObject.Item( "$aArray" ) _ArrayDisplay( $aArray, "Array on client" ) ; Modify array on client For $i = 0 To 100 - 1 $aArray[$i][0] = "Modified" $aArray[$i][1] = "on" $aArray[$i][2] = "client" Next _ArrayDisplay( $aArray, "Modified array on client" ) ; Transfer data $oDataTransferObject.Item( "$aArray" ) = $aArray EndFunc Passing array between AutoIt and VBScriptBecause ROT objects are based on standard COM code, it's possible to exchange data between an AutoIt program and other COM compatible programs e.g. VBScript. The files in Examples\3) IPC Demo2\VBScript\ demonstrate this: 1) Server.au3: #include <GUIConstantsEx.au3> #include "..\..\..\Includes\IRunningObjectTable.au3" Example() Func Example() Local $sArray = "ArrayData" ROT_RegisterObject( Default, $sArray ) ; Default => Object = Dictionary object Local $oArray = ObjGet( $sArray ) ; Dictionary object Local $aArray = [ 123, 123.123, "This is data from AutoIt" ] $oArray( "Array" ) = $aArray Local $sText = "Data exchange between AutoIt and VBScript" Local $hGui = GUICreate( $sText, 400, 300 ) $sText = "Run Client.vbs:" & @CRLF & _ "Open a Command Prompt in the current folder." & @CRLF & _ "Key in ""wscript Client.vbs"" and hit the Enter key." & @CRLF & @CRLF & _ "When you have seen the information in the MsgBox, press the button below." GUICtrlCreateLabel( $sText, 20, 60, 360, 80 ) $sText = "Press Button to continue" Local $idButton = GUICtrlCreateButton( $sText, 20, 180, 360, 30 ) GUISetState( @SW_SHOW, $hGui ) While 1 Switch GUIGetMsg() Case $idButton $aArray = $oArray( "Array" ) MsgBox( 0, "AutoIt: Array from VBScript", "Int: " & $aArray[0] & " (" & VarGetType( $aArray[0] ) & ")" & @CRLF & _ "Flt: " & $aArray[1] & " (" & VarGetType( $aArray[1] ) & ")" & @CRLF & _ "Str: " & $aArray[2] & " (" & VarGetType( $aArray[2] ) & ")" ) Case $GUI_EVENT_CLOSE ExitLoop EndSwitch WEnd GUIDelete( $hGui ) EndFunc Client.vbs: Dim oArray, iAnswer Set oArray = GetObject( "ArrayData" ) iAnswer = MsgBox( "Int: " & oArray( "Array" )(0) & vbCrLf & _ "Flt: " & oArray( "Array" )(1) & vbCrLf & _ "Str: " & oArray( "Array" )(2), 0, "VBScript: Array from AutoIt" ) Dim aArray aArray = Array( 234, 234.234, "This is data from VBScript" ) oArray( "Array" ) = aArray Examples with programs like C# and VB.NET are probably more interesting than VBScript. This way, you can transfer (large) arrays from AutoIt to C# and VB.NET, perform array calculations in compiled code, and return arrays or results back to AutoIt. Here, the AutoIt and C#/VB.NET code are standalone programs that run in their own processes and are connected only through the ROT object. It's a new option to execute code sections that are bottlenecks in interpreted AutoIt code as compiled and possibly multithreaded C#/VB.NET code. Note that such a technique is very different from the technique in Using C# and VB Code in AutoIt through the .NET Framework, where all code runs in the same process. Passing data through ROT Objects (2020-07-11)In IPC Techniques through ROT Objects (Data types section) the AutoIt data types have been tested based on the example for the VarGetType() function in the help file. The data types are sent from Sender to Receiver with these results: $aArray : Array variable type. $dBinary : Binary variable type. $bBoolean : Bool variable type. $pPtr : Int32 variable type. $hWnd : Int32 variable type. $iInt : Int32 variable type. $fFloat : Double variable type. $oObject : Object variable type. $sString : String variable type. $tStruct : Not recognized as a valid variable type. $vKeyword : Keyword variable type. fuMsgBox : Not recognized as a valid variable type. $fuFunc : Not recognized as a valid variable type. $fuUserFunc : Not recognized as a valid variable type. Only the $tStruct and the function data types are not received correctly. The Int32 types for $pPtr and $hWnd can easily be converted to pointer and window handles with the Ptr() and HWnd() functions. In the following section (DllStruct section) it's shown how the $tStruct can be sent by converting the DllStruct to Binary data. In the Large array section (still in the IPC Techniques example) it's shown that even very large arrays can be passed with ROT objects. AutoIt/Perl integration is an example showing how to pass data back and forth between AutoIt and Perl scripts. Also between different programming languages, the data types are preserved with this technique.
