I'm trying to drive a command prompt by sending instructions via a NamedPipe.
This way you can (should) be able to send commands to the command prompt and at the same time "view" the result in the same window.
This is not allowed if you run a command prompt with "opt_flag" parameters (redirected streams) because this will disable StdOut on the cmd itself.
This small (trivial) snippet works for the first command sent to the cmd, but further submissions will fail.
Maybe the problem is in how I use the run () command to start a new cmd with the StdIn redirect from the NamedPipe. It seems that the generated cmd will close automatically after the first reception of the command via NamedPipe.
suggestions on how to make it work are welcome
#include <NamedPipes.au3> #include <WinAPI.au3> ; Creates an instance of a named pipe Global $sPipeName = "\\.\pipe\pipename" Global $hPipe = _NamedPipes_CreateNamedPipe($sPipeName, 1, 1) MsgBox(0, "Debug", "Pipe created. Now open a CMD") ; run a cmd with only StdIn redirected (StdIn data incoming from a pipe) Global $hCMD = Run(@ComSpec & " /K cmd < " & $sPipeName & @CRLF, "c:\") ; ok? MsgBox(0, "Debug", "now Send a command to the cmd via a NamedPipe") _StdInPipeWrite("dir" & @CRLF) MsgBox(0, 'Debug', "further commands will fail" & @CRLF & "now send command 'dir c:\windows'") $sMessage = "Dir c:\windows" & @CRLF _StdInPipeWrite($sMessage) MsgBox(0, 'Debug', "send another command (will also fail)" & @CRLF & "now send command 'echo Hello'") _StdInPipeWrite("echo Hello" & @CRLF) MsgBox(0, "Debug", "end of test") ProcessClose($hCMD) Func _StdInPipeWrite($sMessage) ; =============================================================================================================================== ; This function writes a message to the pipe ; =============================================================================================================================== Local $iWritten, $iBuffer, $pBuffer, $tBuffer $iBuffer = StringLen($sMessage) + 1 $tBuffer = DllStructCreate("char Text[" & $iBuffer & "]") $pBuffer = DllStructGetPtr($tBuffer) DllStructSetData($tBuffer, "Text", $sMessage) If Not _WinAPI_WriteFile( _ $hPipe, _ ; ......

Long time lurker and now forum poster! I'm writing a relatively simple backup script for my firm that automates the copy, compression and organization of Leaver's data on one of our secured NAS systems. I personally found the best method to do this so far was to use 7zG.exe (GUI version of 7Zip which can use command-line too) and it functions quite well!
I would like to retrieve more info on whether any warnings or errors happen in 7Zip during the backup, but I can't quite get my head around the syntax and switches for reading out, it seems any adjustment I make to the RunWait call's string seems to break the backup or give unexpected repercussions! Hopefully its something silly I'm doing as I don't code very often.
Here is the working version:
; Compress the directories one by one in the zip using the listfile.... Local $iPID = RunWait(@ScriptDir & "\bin\7zG.exe a -mx" & $compressionQuality & " -v" & $compressSplitFileSize & " -wc:\temp " _ & $backupToLocation & "\" & $userDirectory & ".7z @bin\listfile.txt -x@bin\excludefile.txt", "", @SW_SHOWDEFAULT, $STDOUT_CHILD) Ultimately I would love to switch entirely to 7za.exe (standalone) so that I can read the progress percentage, current file being uploaded and any warnings or errors could be processed and output to the AutoIT script's GUI I've created rather than jumping in and out of two applications per se.
Im creating a tab
Global $Tab1 = GUICtrlCreateTab(30, 30, 600, 420, $TCS_BUTTONS, -1) And what we see in the function reference:
GUICtrlCreateTab ( left, top [, width [, height [, style = -1 [, exStyle = -1]]]] ) ok in 5 arg I got $TCS_BUTTONS
But How can I use multiple args like this below
Global $Tab1 = GUICtrlCreateTab(30, 30, 600, 420, [$TCS_BUTTONS, $TCS_MULTILINE], -1)
Hello Everyone , Are you tired of searching the forum for getting both the exit code & the stdout output? Then you are in the right place!
With this UDF you can get the both output & exit code of the command or the console app! Or you can get the exit code of another process without having to use RunWait...
