Hi,

Can anyone send me the API example of how to find the current application that has the focus, I tried the other way around, ie: does my VB app still have the focus using the event lostfocus but it does not quite work the way I want.

Some help will be greatly appreciated.

Cheers

mmahdi,
Try this:

Dim hWndCURR As Long
Dim WNDTEXT As String
hWndCURR = GetForegroundWindow()
TXTLEN = GetWindowTextLength(hWndCURR)
WNDTEXT = Space$(TXTLEN + 1)
TXTLEN = GetWindowText(hWndCURR, WNDTEXT, TXTLEN + 1)
MsgBox WNDTEXT

WNDTEXT is the window text of the current application

mmahdi,
I apologize, the code I submitted will return the foreground window, perhaps a more appropriate code would be:
    hWndCURR = GetFocus()
this would go in place of:
    hWndCURR = GetForegroundWindow()

Sekans,

Thanks for the code, the first answer somehow work, however I had to edit the code:

from: WNDTEXT = Space$(TXTLEN + 1)
to: WNDTEXT = Space$(TXTLEN)

the first line returned a string length of whatever the caption of the window is + 1 extra character. I am using the procedure in a timer control. If my app has not got the focus then activate some process.

Thanks
