Find window handle with pid?

[BPM]

I was wondering if there was a way to find a window's handle by using the process ID.

I know I can find it with the windows name, but my problem is I have multipul windows with the same name.

I want to be abel to activate a window by using its process ID

For example,

If Not WinActive($Handle) Then WinActivate($Handle)

How could I get $Handle from just the process ID? ($pid)

So far the only way Ive seen in the documentation to find a windows handle involves the windows name.

WinGetHandle("Title")

Some help would be greatly appriciated. Thank you

Similar question in MSDN magazine a while ago deal with this generically-

http://msdn2.microsoft.com/en-us/magazine/cc301495.aspx.

It would probably be possible to use the dll functions mentioned there to do this.

A native autoit solution might be to use WinGetProcess() and then using advanced window descriptions to enumerate though each iteration of the window until you get one that matches the PID you already have.

There's got to be an easy way to do this.

I think the Dll call function has something to do with it, I saw this code within Nomad's memory UDF's:

Func _MemoryOpen($iv_Pid, $iv_DesiredAccess = 0x1F0FFF, $iv_InheritHandle = 1)
    
    Local $ah_Handle[2] = [DllOpen('kernel32.dll')]
    
    Local $av_OpenProcess = DllCall($ah_Handle[0], 'int', 'OpenProcess', 'int', $iv_DesiredAccess, 'int', $iv_InheritHandle, 'int', $iv_Pid)
    
    $ah_Handle[1] = $av_OpenProcess[0]
    
    Return $ah_Handle
    
EndFunc

This function returns "an array containing the Dll handle and an open handle to the specified process."

But it seems to return the dll handle aswell, and I just want the handle of the process. I haven't ventured into dll functions yet, so I wouldnt know how to modify this code. Maybe this helps though?

Here's an example, in this case i have 5 notepads open, they all have the same title. I know that the PID of one is 4072-

$handle=_GetPIDWindows(4072)
if IsHWnd($handle) then
    WinKill($handle)
EndIf

func _GetPIDWindows($PID)
    $WinList=WinList()
    for $i=1 to $WinList[0][0]
        if WinGetProcess($WinList[$i][1])=$PID then 
            Return $WinList[$i][1]
        EndIf
    Next
    Return 0
EndFunc

Awesome, I got it to work!

Looks like the window list function was the ticket
