Getting process ID from wintitle

14 posts in this topic

Hello, I have searched the forums for an answer but can't seem to find one. Is it possible to get the PID of a process using the title or handle of a window?

Retrieves the identifier of the thread that created the specified window


#include <WinAPI.au3>
_WinAPI_GetWindowThreadProcessId($hWnd, ByRef $iPID)

.

if it is a childprocess, you can give it a variable $PID on creation (ref. to your previous posting)

Func _WinAPI_GetWindowThreadProcessId($hWnd, ByRef $iPID)
    Local $aResult = DllCall("user32.dll", "dword", "GetWindowThreadProcessId", "hwnd", $hWnd, "dword*", 0)
    If @error Then Return SetError(@error, @extended, 0)
    $iPID = $aResult[2]
    Return $aResult[0]
EndFunc   ;==>_WinAPI_GetWindowThreadProcessId

.

.

Return Value Returns the Thread ID of the specified window

 

..

helpfile is wrong on this detail. return value is False or True.

Thanks for all the help, I ended up having my child process write a value in the registry with it's PID, I chose to do it this way so that if the main process fails, and doesn't kill the child process, the next child process will be able to kill the previous child process, thanks for the ideas and suggestions as always though! Great community here, hopefully soon I'll be able to release my big project I've been working on in autoit, and share it here on the forums!

Never realized it was your own child process.

I've had a similar problem in the past, I solved it like this in the child process main loop.

While ProcessExists("MyParentProcess.exe")
       ;main loop
WEnd

i usually call my parent script with cmdline params for child processes (all in one script). in this way all can write to the same local ini file. just to avoid registry spamming.

@Edano - The process id is returned in the varible $ipid.  In your example you are overlaying this with whatever is in the return array.

The Help file could be clearer, but if you read the parameter descriptions it is pretty obvious what is happening.

i did not post an example, it is the genuine  _WinAPI_GetWindowThreadProcessId() function from the _WinApi UDF i quoted.

.

yes the helpfile says

Return Value Returns the Thread ID of the specified window

.

this is wrong. the Thread iD is returned ByRef.

E.

either adjust the helpfile or the function to return the PID as result.

OK, please report to the help file thread so I don't forget to have a look. Thank you.
