AppActivate & Windows 2000

Does anybody know function (API?) replacement for AppActivate?
In Win2000 AppActivate doesn't work :(

I'm using VB5SP3 on Win2000

Many thanx

VB Code:

'Code by Mahbub ([email protected])
'This example requires two forms with on each for one command button.
'Both buttons should be named 'Command1'
 
'In Form1
Private Sub Command1_Click()
    ' Make the window Form2 the active window for the program.  Note that
    ' this function will not make the window the foreground window if the user is currently
    ' working with a separate program.
    Dim retval As Long  ' return value
    retval = SetActiveWindow(Form2.hwnd)  ' set Form2 as the application's active window
End Sub
Private Sub Form_Load()
    Form2.Show
End Sub
 
'In Form2:
Private Sub Command1_Click()
    Dim retval As Long  ' return value
    retval = SetActiveWindow(Form1.hwnd)  ' set Form1 as the application's active window
End Sub
 
'In a module:
Declare Function SetActiveWindow Lib "user32.dll" (ByVal hwnd As Long) As Long

If you want foreground window behavior also, then you may
opt to try:

void SwitchToThisWindow (HWND hWnd, BOOL bRestore); // User32.dll

You'll have to write the VB Declare statement to port it over,
but it will definately do the trick. BTW, use this function as a last
resort because Microsoft does not support it.

Thanx for your answers, but i still have problems...

SetActiveWindow returns 0
SwitchToThisWindow does nothing

Can you take a look at my prog? what's wrong?

VB Code:

Public Const GW_HWNDNEXT = 2
 
Public Declare Function GetParent Lib "user32" (ByVal hwnd As Long) As Long
Public Declare Function GetWindow Lib "user32" (ByVal hwnd As Long, _
  ByVal wCmd As Long) As Long
Public Declare Function FindWindow Lib "user32" Alias "FindWindowA" _
  (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
 
Public Declare Function GetWindowThreadProcessId Lib "user32" _
  (ByVal hwnd As Long, lpdwprocessid As Long) As Long
  
Public Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
        (ByVal hwnd As Long, _
        ByVal lpOperation As String, _
        ByVal lpFile As String, _
        ByVal lpParameters As String, _
        ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
 
Declare Function SetActiveWindow Lib "user32" (ByVal hwnd As Long) As Long
Declare Function SwitchToThisWindow Lib "user32" (ByVal hwnd As Long, ByVal fAltTab As Boolean)
Declare Function GetLastError Lib "kernel32" () As Long
 
Public Function ProcIDFromWnd(ByVal hwnd As Long) As Long
   Dim idProc As Long
  
   ' Get PID for this HWnd
   GetWindowThreadProcessId hwnd, idProc
   ProcIDFromWnd = idProc
End Function
      
Public Function GetWinHandle(hInstance As Long) As Long
   Dim tempHwnd As Long
      
   ' Grab the first window handle that Windows finds:
   tempHwnd = FindWindow(vbNullString, vbNullString)
   
   ' Loop until you find a match or there are no more window handles:
   Do Until tempHwnd = 0
      ' Check if no parent for this window
      If GetParent(tempHwnd) = 0 Then
         ' Check for PID match
         If hInstance = ProcIDFromWnd(tempHwnd) Then
            ' Return found handle
            GetWinHandle = tempHwnd
            ' Exit search loop
            Exit Do
         End If
      End If
   
      ' Get the next window handle
      tempHwnd = GetWindow(tempHwnd, GW_HWNDNEXT)
   Loop
 
End Function
 
Private Sub Command1_Click()
 
progID = Shell("notepad.exe", vbNormalFocus)
        
For i = 1 To 500000
    DoEvents
Next i
 
progID = GetWinHandle(progID)
tempID = SetActiveWindow(progID)
 
End Sub

When I open notepad with vbNormalFocus, it already has focus.

I mean, if the VB application which runs shell hadn't focus.

Look:
If MyVbApp have focus then notepad have focus
If MyVbApp have not focus (e.g. desktop have focus), also the notepad haven't focus

But If i run second shell immediately after notepad, i can set focus to this shell by API, but i can't set focus to the first shell (notepad).

Hope you understand my english :)
