    operator64

    I needed this library to continue working on one or two of my projects. Hopefully it will be of use to someone else too. These functions attempt to perform accurate calculations for the largest Int-64 values, testing for integer overflow and resorting to floats when results go out of range. This library is primarily intended to be used with Int-32 or Int-64 values and it offers no advantage whatsoever to pass floats as parameters. It only makes sense if you intend to perform accurate calculations on large Int-64 values. I know this can be done using strings too, but I prefer not to speculate as to the difference in time penalties. ; #INDEX# ====================================================================================================================== ; Title .........: operator64 ; AutoIt Version : 3.3.14.0 ; Language ......: English ; Description ...: Helper functions for basic maths operations to be used with Int-32 and Int-64 numeric data types. ; Notes .........: Tests for integer overflow and attempts to correct for small inaccuracies affecting certain calculations. ; Return values are cast as Int-32 or Int-64 when possible, otherwise the result will be returned as a double. ; If it is not possible to return an Int-64 data type, the @extended flag is always set to non zero. ; Extended return values indicate that 100% accuracy cannot be guaranteed or that the result is ambiguous. ; The following values are valid for all functions in this library ; |@error = 1 The input or first operand is not an integer. ; |@error = 2 The second operand is not an integer. ; |@error = 3 Internal function error (ignore). ; |@extended = 1 The result is limited to double precision. ; |@extended = 2 The result is not an integer. ; |@extended = 3 The result is out of range for Int-64. ; |@extended = 4 The result is infinity. ; |@extended = 5 The result is an imaginary number. ; When an error occurs, the @extended flag is always set to non zero and a value returned regardless. ; Author(s) .....: czardas ; ============================================================================================================================== ; #CURRENT# ==================================================================================================================== ; _Abs64 ; _Add64 ; _Divide64 ; _Multiply64 ; _Power64 ; _Root64 ; _Subtract64 ; ============================================================================================================================== ; #INTERNAL_USE_ONLY#=========================================================================================================== ; __DoubleTo64 ; __Integer64 ; __OverflowDetect ; __Product64 ; __WholeNumberDivision ; ============================================================================================================================== ; #FUNCTION# =================================================================================================================== ; Name...........: _Abs64 ; Description ...: Returns the absolute value of an integer. ; Syntax.........: _Abs64($iInteger) ; Parameters.....; $iInteger - The integer to operate on. ; Return values .: Returns an Int-32, or Int-64, value. ; Failure returns the executed expression and sets the following flags: ; |@error = 1 The input parameter is not an integer. ; |@extended = 2 The result is not an integer. ; |@extended = 3 The absolute value (2^63) is out of range for Int-64. ; Author.........: czardas ; ============================================================================================================================== Func _Abs64($iInteger) $iInteger = __Integer64($iInteger) If @error Then Return SetError(1, 2, Abs($iInteger)) If $iInteger = 0x8000000000000000 Then Return SetExtended(3, Abs($iInteger)) Return $iInteger < 0 ?

  3. noob62, This may interest you... #include <array.au3> ; create test array local $iSize = 500000 local $aArray[$iSize] local $st = timerinit() for $i = 0 to ubound($aArray) - 1 $aArray[$i] = 'Computer_' & stringformat('%04i',random(1,1000,1)) Next _DBG('Time to generate array') ;-------------------------------------------------------------------- $st = timerinit() _arraydisplay(_SRCH('Computer_0385', $aArray),round(timerdiff($st)/1000,4) & ' seconds') func _SRCH($sSearchString, $aTest) assign($sSearchString,'') For $i = 0 to UBound($aTest) - 1 If IsDeclared($aTest[$i]) Then Assign($sSearchString, Eval($sSearchString) & $i & ',') Next return ( eval($sSearchString) ? stringsplit(eval($sSearchString),',') : 0 ) endfunc func _DBG($str) ConsoleWrite(stringformat('!\t%-50s = %2.4f seconds',$str,timerdiff($st)/1000) & @CRLF) endfunckylomas

  4. And, in case you were wondering, almost all icons in the UI are now vector (they are glyphs in a font called "vPaint UI Glyphs"):

  5. Found it. Babelpad gives me the hex Unicode code, so I have to use Google to find the decimal Unicode code, and then add it to a variable using ChrW(). In the case of 001F, the decimal code is 31, so I was able to "find" the character in my AutoIt script using ChrW (31).

  6. Glad to hear that it works now! @TheDcoder: I will fix it! @J2TeaM: Thx for the info! I will fix both. (And yes the problem is the | char in the extracode)

  7. Hobbyist, You can achieve a sort of "dynamic" variable name using eval. See the code below... ; *** Start added by AutoIt3Wrapper *** #include <GUIConstantsEx.au3> ; *** End added by AutoIt3Wrapper *** #include <GuiListView.au3> #include <array.au3> #AutoIt3Wrapper_Add_Constants=n local $gui010 = guicreate('') local $aSize = WinGetclientsize($gui010) local $list1 = guictrlcreatelistview('Items',0,20,$aSize[0],100) local $list2 = guictrlcreatelistview('Items',0,140,$aSize[0],100) local $list3 = guictrlcreatelistview('Items',0,260,$aSize[0],100) _GUICtrlListView_SetColumnWidth ($list1, 0, $LVSCW_AUTOSIZE_USEHEADER) _GUICtrlListView_SetColumnWidth ($list2, 0, $LVSCW_AUTOSIZE_USEHEADER) _GUICtrlListView_SetColumnWidth ($list3, 0, $LVSCW_AUTOSIZE_USEHEADER) local $btn010 = guictrlcreatebutton('Button',10,$aSize[1] - 30,$aSize[0] - 20,20) for $i = 0 to 9 GUICtrlCreateListViewItem('Item # ' & $i,$list1) GUICtrlCreateListViewItem('Item # ' & $i,$list2) GUICtrlCreateListViewItem('Item # ' & $i,$list3) next guisetstate() while 1 switch guigetmsg() case $gui_event_close Exit case $btn010 ; set all listviews to white for $i = 1 to 3 GUICtrlSetBkColor(eval('list' & $i),0xffffff) next ; set a random listview to maroon GUICtrlSetBkColor(eval('list' & random(1,3,1)),0xaa0000) EndSwitch WEnd kylomas

  9. Hi vinhphamvn! Looks there are some encoding problems in the ISN. I attached a fixed exe..please can you test it? Do the following: Edit your testfile with for example Scite4AutoIt. In the file you will see the "wrong" text. Correct it as it should be. Use my new AutoIt Studio exe and try if ISN opens/saves the file now correctly. (UTF-8 mode must be enabled in the settings) Thanks for your help! [removed]

  10. If you need to ONLY transfert ONE file, all you have to do when transfert is done is to close the connection. No need for completion markers. If you need to transfert multiple files, end marker isn't the best solution. You'll have to announce file size first, then transfert file.

  11. ok, try this TCPStartup() $ip = @IPAddress1 $listen = TCPListen($ip, 4444) Local $data, $socket = -1 Do If $socket = -1 Then $socket = TCPAccept($listen) EndIf If $socket <> -1 Then $data &= TCPRecv($socket, 1024 * 1024) EndIf Until StringRight($data, 8) = "Complete" TCPSend($socket, "Complete") $data = StringTrimRight($data, 8) $op = FileOpen('khang.jpg', 18) FileWrite($op, $data) FileClose($op)client TCPStartup() $ip = @IPAddress1 Do $connect = TCPConnect($ip, 4444) Until $connect <> -1 $op = FileOpen('IMG.jpg', 16) TCPSend($connect, FileRead($op) & "Complete") FileClose($op) Do Sleep(1) Until TCPRecv($connect, 8) = "Complete"

  12. I finally found the stupid solution. it took me 2 years. I did other things too. OK here it goes. All you have to do is put the path to program in Start in (optional). I also did this, maybe is need: You should grant to the specified user access to COM automation factory: 1) Start->Run->dcomcnfg 2) Component Services->Computers->My Computer 3) Right-click My Computer, Properties 4) COM Security tab, Launch and Activation Permissions, Edit Default 5) Add all access rights for the specified user, you are using to run scheduled task. Hope it helps. Please replay if it is working for you.

  15. As has been mentioned -- what about using the clipboard? For instance, can you send "^a" to select all of the text held by the control (if it is some sort of edit control), then "^c" to copy it, then finally get the clipboard contents with ClipGet()?
