hi, I made a software for managing dtmf tones. For the moment the pc audio output is connected to an Arduino with an mt8870 module which decodes the tone and returns the correct value via serial. I wanted to make sure not to use external hardware and so I tried with the bass.dll library to read the microphone input. I can read the volume and interpret the data, but I haven't found a way to handle the dtmfs. Searching the internet I found a project with source in Delphi and C++ with examples to import a library called DTMFScanner.dll (https://www.3delite.hu/Object Pascal Developer Resources/download.html#dtmf) the DTMFScannerLibrary.h file is attached to this post. There are examples on how to use the external library with Delphi too I tried to modify an example of the bass library to integrate the request for the DTMFScanner.dll library but it always returns the value 0. I'm afraid I'm using the wrong library recall method This is my script: #include 'Bass.au3' #include <WinAPICOM.au3> #include <WinAPIConv.au3> #include <Array.au3> Global $hStream, $iLong, $nLeft, $nRight, $iColor Global $ID_GUI = GUICreate('BASS Audio Levels', 190, 200, -1, -1, Default, 0x00000008) GUICtrlCreateLabel('L', 52, 20, 34, 22) GUICtrlCreateLabel('R', 82, 20, 34, 22) Global $ProgressBarL = GUICtrlCreateProgress(50, 40, 14, 100, 0x04) Global $ProgressBarR = GUICtrlCreateProgress(80, 40, 14, 100, 0x04) Global $InputL = GUICtrlCreateLabel('', 50, 150, 34, 22) Global $InputR = GUICtrlCreateLabel('', 80, 150, 34, 22) Global $DtmlDLL Global $parameters = DllStructCreate("ptr FileName; dword Channel; float Treshold; int Thread; int64 User; ptr DetectCallback") Global $inputChannel = 3 ;<------- my mic input Global $result1 GUISetOnEvent(-3, '_Exit') Opt('GUIOnEventMode', 1) GUISetState(@SW_SHOW, $ID_GUI) _BASS_Startup(@ScriptDir & '\Bass.dll') If @error Then Exit MsgBox(16, 'BASS Function Error', 'EC1') _BASS_Init(16, -1, 44100, 0, 'NULL') If @error Then Exit MsgBox(16, 'BASS Function Error', 'EC2') _BASS_RecordInit(-1) If @error Then Exit MsgBox(16, 'BASS Function Error', 'EC3') ; choose input.

Hi here's another UDF for the serial port. It is very similar to CommAPI using kernel32.dll, but all code is packed into a single file without any dependencies, not even using WinAPI.au3. It differs from existing UDF that it doesn't allow a timeout when reading, instead it always returns immediately, either with the requested amount ob bytes read or with a failure status. And of course there is a function provided to query the amount of available bytes in the receive buffer. The reason behind this design decision: You can do 1000 other things in the main loop while checking from time to time if enough data bytes arrived. There's no point to block the program waiting for the serial port. It is currently a work-in-progress, as I didn't test all functions yet. The code was developed and tested on Windows 7 64 bit. The ComUDF-Tests.au3 shows some tests and basic usage of the UDF. Maybe there's no reason to use this UDF, given the existence of the others UDFs, but I did it to get to know DllCall better - I use structs no only to pass but also to get data back (I don't use the array returned by DllCall to read that data, unless required). You're welcome to test it on older and newer Windows versions. Here's a list of the implemented functions: ; _ComListPorts ; _ComOpenPort ; _ComSetTimeouts ; _ComClosePort ; ; _ComSetBreak ; _ComClearBreak ; _ComGetInputcount ; _ComGetOutputcount ; _ComClearOutputBuffer ; _ComClearInputBuffer ; ; _ComSendByte ; _ComReadByte ; _ComSendBinary ; _ComReadBinary ; ; _ComSendChar ; _ComReadChar ; _ComSendCharArray ; _ComReadCharArray ; _ComSendString ; _ComReadString ; ; __ComClearCommError ; __PurgeComm Maze ComUDF.au3 ComUDF-Tests.au3

We have here a working script (Found on this forum - someone said its best way to set timers) I want to set timers in my program cause AdLibRegister crashes, infinite loops etc. Its a working small program to test these timers below. #include <WindowsConstants.au3> #include <GuiConstantsEx.au3> Global $iMemo _Main() Func _Main() Global $hGUI Global $timerID1 = 1, $timerID2 = 2 Global $callBackFunc1, $callBackFunc2 Global $timerName1, $timerName2 $hGUI = GUICreate("My Timers", 400, 296) $iMemo = GUICtrlCreateEdit("", 2, 32, 396, 226, BitOR($WS_HSCROLL, $WS_VSCROLL)) GUICtrlSetFont($iMemo, 9, 400, 0, "Courier New") GUISetState() setTimer($callBackFunc1, $timerName1, $timerID1, 1000, 'hello') setTimer($callBackFunc2, $timerName2, $timerID2, 2000, 'hello2') While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ExitLoop EndSwitch WEnd killTimer($timerName1, $callBackFunc1) killTimer($timerName2, $callBackFunc2) EndFunc ;==>_Main ; ================= MY FUNCS ============================ Func setTimer(ByRef $callBackFunc, ByRef $timerName, $timerID = 1, $time = 1000, $funcName = 'hello') $callBackFunc = DllCallbackRegister($funcName, "none", "hwnd;int;int;dword") $timerName = _WinAPI_SetTimer($hGUI, $timerID, $time, DllCallbackGetPtr($callBackFunc)) EndFunc Func killTimer($timerName, $callBackFunc) _WinAPI_KillTimer($hGUI, $timerName) DllCallbackFree($callBackFunc) EndFunc ; ============================================= ; Write a line to the memo control Func MemoWrite($sMessage) GUICtrlSetData($iMemo, $sMessage & @CRLF, 1) EndFunc ;==>MemoWrite Func _WinAPI_KillTimer($hWnd, $iIDEvent) Local $iResult = DllCall("user32.dll", "int", "KillTimer", "hwnd", $hWnd, "int", $iIDEvent) If @error Then Return SetError(-1, -1, 0) Return $iResult[0] <> 0 EndFunc ;==>_WinAPI_KillTimer Func _WinAPI_SetTimer($hWnd, $iIDEvent, $iElapse, $pTimerFunc = 0) Local $iResult = DllCall("user32.dll", "int", "SetTimer", "hwnd", $hWnd, "int", $iIDEvent, "int", $iElapse, "ptr", $pTimerFunc) If @error Then Return SetError(-1, -1, 0) Return $iResult[0] EndFunc ;==>_WinAPI_SetTimer Func _TimerCallBackFunc($hWnd, $Msg, $iIDTimer, $dwTime) MemoWrite("Timer " & $iIDTimer & " Fired") For $i = 999 To 1 Step -1 ConsoleWrite($i & @CRLF) Next EndFunc ;==>_TimerCallBackFunc ; ============== Funs to call =============================== Func hello($hWnd, $nMsg, $iIDTimer, $dwTime) MemoWrite("Timer " & $iIDTimer & " Fired") For $i = 999 To 1 Step -1 ConsoleWrite($i & @CRLF) Next EndFunc ;==>_TimerCallBackFunc Func hello2($hWnd, $nMsg, $iIDTimer, $dwTime) MemoWrite("Timer " & $iIDTimer & " Fired") For $i = 999 To 1 Step -1 ConsoleWrite($i & @CRLF) Next EndFunc ;==>_TimerCallBackFunc And i wanted to apply these timers to my final program. I get error: error: doingThings() called by a previous line with 0 arg(s). Min = 4. First previous line calling this Func is 31. Func doingThings($hWnd, $nMsg, $iIDTimer, $dwTime) There are pieces of code below: There I replaced AdlibRegister by setTimer and calling it like in previous working program (just doingThings in last param in setTimer function) Func r_offOn_doingThings() If _Metro_CheckboxIsChecked($r_offOn_doingThings) Then _Metro_CheckboxUnCheck($r_offOn_doingThings) ;AdlibUnRegister("doingThings") killTimer($timerName1, $callBackFunc1) Else If _checkDeclared(True,False) == False Then ; check if is declared to run func (HP,TITLE,REGION)- core_funcs Else _Metro_CheckboxCheck($r_offOn_doingThings) setTimer($callBackFunc1, $timerName1, 1, 1600, "doingThings") ;AdlibRegister("doingsThings", 1800) EndIf EndIf EndFunc And function name with params looks like this Func doingThings($hWnd, $nMsg, $iIDTimer, $dwTime) EndFunc #include Timers.au3 #CS THere are globals vars: globalVariables/timers ByRef $callBackFunc: var ByRef $timerName: var $timerID = 1: var ID $time = 1000: how often call func $funcName: function to call #CE Global $timerID1 = 1, $timerID2 = 2 Global $callBackFunc1, $callBackFunc2 Global $timerName1, $timerName2 Func setTimer(ByRef $callBackFunc, ByRef $timerName, $timerID = 1, $time = 1000, $funcName = "doingThings") $callBackFunc = DllCallbackRegister($funcName, "none", "hwnd;int;int;dword") $timerName = _WinAPI_SetTimer($GUI, $timerID, $time, DllCallbackGetPtr($callBackFunc)) EndFunc Func killTimer($timerName, $callBackFunc) _WinAPI_KillTimer($GUI, $timerName) DllCallbackFree($callBackFunc) EndFunc Func _WinAPI_KillTimer($hWnd, $iIDEvent) Local $iResult = DllCall("user32.dll", "int", "KillTimer", "hwnd", $hWnd, "int", $iIDEvent) If @error Then Return SetError(-1, -1, 0) Return $iResult[0] <> 0 EndFunc ;==>_WinAPI_KillTimer Func _WinAPI_SetTimer($hWnd, $iIDEvent, $iElapse, $pTimerFunc = 0) Local $iResult = DllCall("user32.dll", "int", "SetTimer", "hwnd", $hWnd, "int", $iIDEvent, "int", $iElapse, "ptr", $pTimerFunc) If @error Then Return SetError(-1, -1, 0) Return $iResult[0] EndFunc ;==>_WinAPI_SetTimer Thats it. And why in first working program it does not say this function below is calling with 0 args but Min is 4? setTimer($callBackFunc1, $timerName1, 1, 1600, "doingThings") When I applied this code to my final program it wants 4 arguments in function call. I rode i cant pass parameters to the callback func . What I have to do. I tried something like this: Func doingThings($hWnd = Default, $nMsg = Default, $iIDTimer = Default, $dwTime = Default) but then function is not working dont know whats going on

I've been working with the Windows Credentials store to store credentials for lots of RDP connections. I'm also using this code in other scripts to store and retrieve "legacy" credentials for my scripts that have a Save Password checkbox. All goes well, until someone requests a button to display a list of all saved credentials. I found the CredEnumerate call and it looks like it's working but the Target and UserName field that I want is stored inside an array of pointers and I can't figure out how to get data from inside that. I found a post from 2009 that talks about this, but there was never a solution. Below are my functions put into an example script. the _Credentials_Enumerate() is where i'm having problems.

Hello Autoit, I'm very new to DllCall function, in fact never used it, but I'm just curious about it. I found @toasterking's awesome beginner friendly dll GUI: I searched for some easier functions (less input / less output parameters), and I found GetFileSize function (I didn't modify his code, just using the GUI): https://learn.microsoft.com/en-gb/windows/win32/api/fileapi/nf-fileapi-getfilesize So, this is what I did: The function itself is executing like this, but the output is 0 and -1 DllCall("kernel32.dll","int","GetFileSize","HANDLE","D:\DllCall GetFileSize Example.au3","DWORD*","$hello") Then, I tried to execute my script (very simple) and put it into D drive: ;DllCall("kernel32.dll", "int", "GetFileSize", "HANDLE", "D:\DllCall GetFileSize Example.au3") $aDllCallReturn = DllCall("kernel32.dll","int","GetFileSize","HANDLE","D:\DllCall GetFileSize Example.au3","DWORD*","$hello") For $i = 0 To UBound($aDllCallReturn) - 1 ConsoleWrite($i & ": " & $aDllCallReturn[$i] & @CRLF) ;MsgBox(0, $i, $aDllCallReturn[$i]) Next ;ConsoleWrite($hello & @CRLF) The result is as the following (same as the screenshot): 0: -1 1: 0x00000000 2: 0 This file size is 403 bytes in my computer, it's very small, I expected to see 403 somewhere, but I don't know where I made it wrong. So, now I have some questions: 1. Do I really need to use lpFileSizeHigh or can I use "hello"? 2. Do I always have to put $ in the beginning of the parameter? I tried without $ in his GUI, I got an error. So, I think $ is a must. 3. But if I write as $hello (expecting this will store the file size), when I ConsoleWrite it, Autoit becomes angry because "undeclared global variable". 4. If somehow $hello will be the output to my file size, why do I need to return an array $aDllCallReturn which contains 3 elements? So, I have one $hello + 3 items from the array = I have 4 outputs total. But Microsoft says this function has only one return "[out, optional] LPDWORD lpFileSizeHigh ". I'm confused. Please note that; the goal for me is to use the DllCall function, not to get the file size by using FileGetSize() or some other existing functions.

This is relevant From here https://stackoverflow.com/questions/3454315/is-it-possible-to-pin-a-dll-in-memory-to-prevent-unloading I use several UDFs on the Forum to do various things. Those UDFs work very well. Effectively the UDFs are DLL wrappers, that make it possible to access DLL functions easily without the long hard slog of DLLCall() every time. However, I have now run into the issue that multiple UDF DLLCalls are slow. Not mind numbingly slow, but slow enough to become noticeable with a large of repeated function calls. So I was wondering, is it possible to "load a DLL into memory" and leave it there for the duration of my script's lifetime, avoid repeated DLL on-disk reads with a persistent in memory DLL? From Microsoft https://docs.microsoft.com/en-us/windows/desktop/dlls/about-dynamic-link-libraries Looks like what I want to do is: load-time dynamic linking, So next question, (a) how do I do this with AutoIt (b) How would this impact on standard AutoIt type DLL calls? The point is speed. Is there a different approach? Or am I barking up the wrong tree? Skysnake

Hi - Currently I'm playing around with Windows Credential Manager. I'm trying to access it with DllCall("advapi32.dll", ...) using the functions 'CredWriteW', 'CredReadW' and 'CredDeleteW'. All well. Another function I have to deal with is 'CredEnumerateW': https://docs.microsoft.com/en-us/windows/desktop/api/wincred/nf-wincred-credenumeratew/ . That's the test code I have so far: #include <Array.au3> #include <String.au3> Local $tCredentialsCount = DllStructCreate("DWORD;") Local $tPointerToArrayOfPointers = DllStructCreate("PTR;") ; Local $tPointerToArrayOfPointers = DllStructCreate(_StringRepeat("PTR;", 200)) ; ??? Local $aResult = DllCall("advapi32.dll", "BOOL", "CredEnumerateW", _ "WSTR", Null, "DWORD", 1, "DWORD", DllStructGetPtr($tCredentialsCount), "PTR", DllStructGetPtr($tPointerToArrayOfPointers)) If (Not @error) Then Local $iCredentialsCount = DllStructGetData($tCredentialsCount, 1) _ArrayDisplay($aResult, $iCredentialsCount) Local $hPointerToArrayOfPointers = DllStructGetData($tPointerToArrayOfPointers, 1) MsgBox(0, "$hPointerToArrayOfPointers", $hPointerToArrayOfPointers) ; Fails... For $i = 1 To 10 ; $iCredentialsCount MsgBox(0, $i & "___" & (($i * 2) - 1), DllStructGetData($tPointerToArrayOfPointers, ($i * 2) - 1)) Next $tCredentialsCount = 0 $tPointerToArrayOfPointers = 0 DllCall("advapi32.dll", "NONE", "CredFreeW", "PTR", $hPointerToArrayOfPointers) EndIf The DllCall seems to function properly - I get a valid count of credentials (on my computer ~ 133) and a pointer "to array of pointers". What is meant by "array of pointers"? Microsoft says: Pointer to an array of pointers to credentials. The returned credential is a single allocated block. Any pointers contained within the buffer are pointers to locations within this single allocated block. How to access these pointers... Contained within the buffer??? Any information you can provide me would be greatly appreciated.

Hello, I'm trying to figure out how to add attributes to a Credentials Store. I have been using it to store Creds and I was using the Comments to store some limited data but I'd really like to start using the 64 possible Attributes so I don't need to use the Registry to store misc information my script needs. I have been trying to figure this our for a few days now and I'm able to create the structure, but it fails with Invalid Parameter when trying to add the item to the store. Any ideas or pointers to where to get some further information on this?

Any ideas?

So first things first the example in the help file for _WinApi_Enum_Windows has an error ;_ArrayDisplay($aResult, "_WinAPI_EnumWindows", Default, Default, Default, Default, "#|Handle|Class|Title|Text|Process") Should Be _ArrayDisplay($aResult, "_WinAPI_EnumWindows", Default, Default, Default, "Handle|Class|Title|Text|Process") Next is a bit of helpful info on LPCSTR in a callback function it needs to be passed as a PTR DllCallbackRegister($sFUNCT, $sRETURN, "ptr") Finally on to my question I'd want to call EnumPropsEX and pass a string through lparam + append to it rather than declaring anything globally I can Come up with two ways to do this The second it a lot more code but possibly safer but the first way I think Should do 1. From a bit of testing It seems AutoIt won't overflow a DllStruct? 2. Are strings passed through DLL call guaranteed to be 'an ANSI string (a minimum of 65536 chars is allocated)' as the Helpfile clearly states? #include <Array.au3> #include <WinAPI.au3> Example() Func Example() Local $aWindows = _WinAPI_EnumWindows() Local $aResult[$aWindows[0][0]][6] For $i = 1 To $aWindows[0][0] $aResult[$i - 1][0] = "0x" & Hex($aWindows[$i][0], 8) $aResult[$i - 1][1] = $aWindows[$i][1] $aResult[$i - 1][2] = WinGetTitle($aWindows[$i][0]) $aResult[$i - 1][3] = WinGetText($aWindows[$i][0]) $aResult[$i - 1][4] = WinGetProcess($aWindows[$i][0]) $aResult[$i - 1][5] = _ArrayToString(EnumProps($aWindows[$i][0]), ", ", 1) Next _ArrayDisplay($aResult, "_WinAPI_EnumWindows", Default, Default, Default, "Handle|Class|Title|Text|Process|Properties") EndFunc ;==>Example Func EnumProps($hWnd, $vDLL = 'user32.dll') ; Create callback function.

So I had this Idea of creating a tooltip which shows me my ping. That itself was made quickly and I thought too add a couple features. I want the tooltip background to be a different color depending on the ping. (good ping is green, medium ping is yellow,...) So how do I color in a tooltip? google brought me to this: where in the comments I found this: $s = "LOW" ToolTip($s, 0, 0, "Battery Information");, $icon) $H_TOOLTIP1 = WinGetHandle($s) DllCall("UxTheme.dll", "int", "SetWindowTheme", "hwnd", $H_TOOLTIP1, "wstr", "", "wstr", "") DllCall("user32.dll", "int", "SendMessage", "hwnd", $H_TOOLTIP1, "int", 1043, "int", 2552550, "int", 0) Sleep(1000) Which I then used in my code with different color codes... Trial and Error brought me these that I wanted to use: The Problem is if I loop through my code it only sets the color for the 1st loop and then sticks to it. The real problem is tho that I don't exactly understand the dllcalls... And I guess that's why it isn't working So if someone would be so awesome to explain to me how they work, or at least can give me a list of these parameters then I would really appreciate that and learn something new Obviously a solution to my problem is awesome aswell ^^ I run this under Windows 8.1 There is my code in a paste. https://pastebin.com/q525f7mS

Hello Guys, once aggain I need your help on a DLL Topic I need to pass arguments to my function via a structure, because I am limited to only one argument that can be passed. But I don't think that thats so important. So here's my approach: C++ Code (just the important part): extern "C" { struct ParamStruct { const char* test1; const char* test2; const char* test3; int size; }; int testFunc(struct ParamStruct * params) { return params->size; } } And thats how I try to call the function using Autoit: Local $struct = "struct;char shapefile[128];char output[128];char filename[128];int size;endstruct" Local $tTest = DllStructCreate($struct) DllStructSetData($tTest, "test1", "Bla") DllStructSetData($tTest, "test2", "BlaBla") DllStructSetData($tTest, "test3", "BlaBlaBla") DllStructSetData($tTest, "size", 40) $dll = DLLOpen("myDLL.dll") $ret = DllCall($dll, "int:cdecl", "testFunc", "STRUCT*", DllStructGetPtr($tTest)) MsgBox(0, 0, $ret[0]) DllClose($dll) Just for testing I want the function to just return the integer value in the struct. But this aint working. I tested many things, but still I'm not able to get it running. I even don't know if the mistakes are in the C++ code or the Autoit code or both .. I'm not that skilled at C++ and also not that skilled at Autoit DLLCalls :-/ I would really appreciate some help! Kind regards, leo

Hello, I have compiled a reference DLL in VS 2015 Community and this DLL works fine with project for which it is used. There is an interface from which u can access functions in DLL. Developers stated that this DLL is almost universal and can be used with any language with minor changes. I am trying to access its function from Autoit script and got an error 3, after calling DLLCall - "function" not found in the DLL file. Please have a quick look, I feel I miss something in C++ library with exporting functions and I do not know what to add as I am new to C++. Thank you. Source files and script also attached. Here is my script. Local $dll = DllOpen("C:\Users\Home\Desktop\dll\user.dll") ConsoleWrite("$dll handle = " & $dll & @CRLF) ;$dll handle = 1 Local $result = DllCall($dll, "double:cdecl", "ProcessQuery", "str", "dll$mynumber") If @error > 0 Then ConsoleWrite("Error: " & @error & @CRLF) ;Error = 3 If IsArray($result) Then ConsoleWrite("Array returned!" & @CRLF & "dll$mynumber: " & result[1]) Else ConsoleWrite("$result is not array. : " & $result & @CRLF) ;$result = 0 EndIf DllClose($dll) And here is dll source.

Hello! There's a DLL, which I want to use in my script. There's the manual for that DLL. I'm trying to use any function from the manual in DllCall() and I get @error=3 ("function" not found in the DLL file). Why is that? How do I fix it? PEiD says that DLL is "Microsoft Visual C++ 6.0 DLL". Is that compatible with AutoIt? How do I use it? Please help. ProgGuide.pdf drvInterface.dll

Hi guys. I try to choose an algorithm to compress some string data in-memory, without file medium to store in sqlite as blob. I plan to store about 100k blobs each 80k symbols (uncompressed). First opinion was LZMA udf by Ward, but udf file doesn't exist. Then i tried to use BZIP2 dll in DllCall, but it simply doesn't work and throws @error = 1. Here is an example: What should I do with this error? Where am I wrong? Thanks.

Hello fellas! The other night night i was converting a Msdn function to autoit and I stumbled across this topic Which inspired me like crazy and I decided to take it a step further and require the user to make almost ZERO effort to export a c++ Msdn function and or a Structure to AutoIt Shoutout to toasterking So after 18-20 effective hours: The GUI is really simple, all you need is a link to a MSDN page and the program does the rest, most of the options is just for user preferences. On the inside I have spent a decent amount of work to make sure the code come out correctly, any particular event during the conversion will get fed-back to the user, so he or she will know if anything noticeable happen. Regular DllCall example http://i.imgur.com/HZLijeu.png Struct example http://i.imgur.com/l3j6wTR.png Expand spoiler for more pictures In the "Msdn Examples" folder you will find some examples of code i have generated, in most of them I only manually added 2-3 lines to make them work. If you dont know where to get these functions you can browse the MSDN Library https://msdn.microsoft.com/en-us/library/ee663300(v=vs.85).aspx and look for any function refrence, or just google "somethingsomething msdn" and the first result will almost always contain the function you are looking for. Here is some functions you can play around with https://msdn.microsoft.com/en-us/library/windows/desktop/ms724390(v=vs.85).aspx https://msdn.microsoft.com/en-us/library/windows/desktop/ms633519(v=vs.85).aspx https://msdn.microsoft.com/en-us/library/windows/desktop/ms645505(v=vs.85).aspx https://msdn.microsoft.com/en-us/library/windows/desktop/ms724408(v=vs.85).aspx I would really appreciate any kind of feedback, improvements or requests If you get any type of error just post the MSDN url + the error message and ID and I will troubleshoot it. Update 0.2 Fixed some minor issues Added highlight for a more pleasent view Fixed minor bugs Made it run faster when working with the same URL (It dosent load the page entierly) No struct search is now done when no POINTER is used in the call Added more options for the user Update 0.3 Removed _IeNavigate and fixed the template for DllCall not including function name Update 0.4 Switched method to InetGet from _Ie* H0tfix3s Update 0.5 Added more options for function-layout Removed old code Added more auto detection Now using @TmpDir instead of @ScriptDir for html files etc. Update 0.6 More Output logic added Added a detection for SAL aswell, since it seems to be inconsistent according to MSDN community and myself.
