Hi all,

I have an application running on several xp, vista and 7 computers. (access 
versions >= a2k, db format = access 2000).

This application communicates with other applications using keybd_events and 
appactivate

On some computers running vista (not all, why why why?), AppActivate often 
hangs in these cases:
    * when you put a windows in background, and try to activate it,
    * when you minimize then maximize some times (1, 2, 3 times) then try to 
activate it.

The problem can be reproduced at will on any of these computers (and the 
problem doesn't occur on other computers running xp or even vista using the 
same application).
The window to be activated is retrieved through the GetWindowTextA function 
in user32.dll, so it is correct!
(Private Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" 
(ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long).

I would like to know if there is a patch (vista sp2 doesn't change anything) 
or if someone knows a reliable alternative to AppActivate.

Regards,
Alain

Vista has some security improvements which my interfere here. A simple 
test: Logon as a user with administrative privileges. Disable UAC. Start 
Access using 'Run As  Administrator'. Run your database. If it works 
then it is caused by this.
Otherwise you need to be more specific and yuo should post a concise and 
complete example.

If I am administrator AND UAC is disabled the problem still occur.
We will try to create a sample.
Meanwhile, if someone has a workaround (vba code to restore a window then 
trigger a click in the titlebar, it might be useful).

Regards,
Alain
