hi friends,
how to get the window handle from the process id.
thanks
I am not sure you can as it's a one to many relationship :(
1 process can have many handles
1 handle has only 1 process
Do you know the caption/title of the window in question?
Woka
i have the exe name
Again...an exe can create hundreds of windows handles...:(
U need to know the exact window you want to find...
What is it for?
Woka
i want to kill that process..
Do a search on VBF for TerminateProcess...
I was involved in a thread a few weeks back that was soley on killing a process, however, I am not sure how to get the ProcessID from the process name...:(
Here's what the API guide has, not sure if it helps much though:
WokaVB Code:
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As Long, ByVal lpWindowName As Long) As Long Private Declare Function GetParent Lib "user32" (ByVal hwnd As Long) As Long Private Declare Function SetParent Lib "user32" (ByVal hWndChild As Long, ByVal hWndNewParent As Long) As Long Private Declare Function GetWindowThreadProcessId Lib "user32" (ByVal hwnd As Long, lpdwProcessId As Long) As Long Private Declare Function GetWindow Lib "user32" (ByVal hwnd As Long, ByVal wCmd As Long) As Long Private Declare Function LockWindowUpdate Lib "user32" (ByVal hwndLock As Long) As Long Private Declare Function GetDesktopWindow Lib "user32" () As Long Private Declare Function DestroyWindow Lib "user32" (ByVal hwnd As Long) As Long Private Declare Function TerminateProcess Lib "kernel32" (ByVal hProcess As Long, ByVal uExitCode As Long) As Long Private Declare Function GetCurrentProcess Lib "kernel32" () As Long Private Declare Function Putfocus Lib "user32" Alias "SetFocus" (ByVal hwnd As Long) As Long Const GW_HWNDNEXT = 2 Dim mWnd As Long Function InstanceToWnd(ByVal target_pid As Long) As Long Dim test_hwnd As Long, test_pid As Long, test_thread_id As Long 'Find the first window test_hwnd = FindWindow(ByVal 0&, ByVal 0&) Do While test_hwnd <> 0 'Check if the window isn't a child If GetParent(test_hwnd) = 0 Then 'Get the window's thread test_thread_id = GetWindowThreadProcessId(test_hwnd, test_pid) If test_pid = target_pid Then InstanceToWnd = test_hwnd Exit Do End If End If 'retrieve the next window test_hwnd = GetWindow(test_hwnd, GW_HWNDNEXT) Loop End Function Private Sub Form_Load() 'KPD-Team 1999 'URL: [url]http://www.allapi.net/[/url] 'E-Mail: [email][email protected][/email] Dim Pid As Long 'Lock the window update LockWindowUpdate GetDesktopWindow 'Execute notepad.Exe Pid = Shell("c:\windows\notepad.exe", vbNormalFocus) If Pid = 0 Then MsgBox "Error starting the app" 'retrieve the handle of the window mWnd = InstanceToWnd(Pid) 'Set the notepad's parent SetParent mWnd, Me.hwnd 'Put the focus on notepad Putfocus mWnd 'Unlock windowupdate LockWindowUpdate False End Sub Private Sub Form_Unload(Cancel As Integer) 'Unload notepad DestroyWindow mWnd 'End this program TerminateProcess GetCurrentProcess, 0 End Sub
Here you go...this should do the trick:
