[WD26] How to detect if the Application is in fore/background
October 20, 2021 03:11PM
Hi,

I need to know if the application is in foreground or background or minimized.

Winstatus(Win_Main) shows always "active".

Any Ideas ?

I don't know how to detect it at any given time, but you can manage flags and set them in several event codes:
- losing focus
- gaining focus
- changing dimension of window (where you can check for minimize)

Hi Argus,

finally I use minimize. But the background flag is difficult to manage because "focus" is a property of a window an not the application.

If my application opens a child window, the main window has also not the focus.

Hi Michael,

WinStatus [help.windev.com] is used to bring an app into the foreground and make it active.

Kind regards,

Hi Guenter,

see my post#1, this shows always "active". I need a method to check if the whole application is in fore or background.

Hi Michael,

with WinStatus you SET it to TopActive which is what you want!?

No, I must send notifications like Outlook if the Application is in the background.
