Switch focus to window with process name?

2 posts in this topic

Hi,

The program i'm trying to automate has a diffrent classid and title everytime i run it. But the processname in TaskManager is stays the same.

How can i switch window focus to that process by just knowing the process name?

Thanks

I think this function can help you.

#include <array.au3>
$iPid = Run("notepad.exe")
Sleep(100) ; allow notepad to create window
$aArray = _WinGetInfoByProcess("notepad.exe", 1)
_ArrayDisplay($aArray, "by Name, only visible windows")

Func _WinGetInfoByProcess($vProcess, $nShow = 2)
    ;
    ;===============================================================================
    ;
    ; Function Name:    _WinGetInfoByProcess
    ; Description::     Get Window Handle of Process
    ; Parameter(s):     $vProcess = Processname(e.g. "Notepad.exe") or Processnumber(e.g. 4711 )
    ;                   $nShow = -1 "All (Visble or not)"
    ;                   $nShow = 0 "Not Visible Only"
    ;                   $nShow = 1 "Visible Only"
    ;                   $nShow = 2 "Return handle of newest  window " (Default)
    ; Requirement(s):   none
    ; Return Value(s):
    ;                   @extended = returns number of entries in the array
    ;                   @error = 0 AND $nShow = 2 (default)  returns handle of newest window
    ;                   @error = 0 returns array with processinfos
    ;                              n = 1 to @extended
    ;                              Array[n][0] shows windows title.
    ;                              Array[n][1] shows windows handle.
    ;                              Array[n][2] shows windows Pid.
    ;                   @error = 1 Process not found.
    ;                   @error = 2 Window not found.
    ; Author(s):        inspired by Smoke_N's script _WinGetHandleByPID()
    ;                   but to handle more than one process with the same name
    ;                   and to return handle of newest window ($nShow = 2).
    ; tested versions:  Autoit 3.3.0.0 
    ;
    ;===============================================================================
    ;
    If Not ProcessExists($vProcess) Then Return SetError(1, 0, 0) ; no matching process
    Local $iWinList, $aWinList = WinList()
    Local $iResult, $aResult[UBound($aWinList)][3]
    Local $iProcessList, $aProcessList = ProcessList($vProcess)
    If $aProcessList[0][0] = 0 Then Local $aProcessList[2][2] = [[1, 0],["", $vProcess]]
    For $iWinList = 1 To $aWinList[0][0]
        For $iProcessList = 1 To $aProcessList[0][0]
            If WinGetProcess($aWinList[$iWinList][1]) = $aProcessList[$iProcessList][1] Then
                If $nShow > -1 And Not $nShow = (2 = BitAND(WinGetState($aWinList[$iWinList][1]), 2)) Then ContinueLoop
                $iResult += 1
                $aResult[$iResult][0] = $aWinList[$iWinList][0]
                $aResult[$iResult][1] = $aWinList[$iWinList][1]
                $aResult[$iResult][2] = $aProcessList[$iProcessList][1]

        Next
    Next
    If $iResult = 0 Then Return SetError(2, 0, 0) ; no window found
    ReDim $aResult[$iResult + 1][3]
