First of all this is in the C++ section, i do not want any VB or C# answers.
Im looking for the opposite of WM_ACTIVATE, because i want my program to stop updating some stuff that uses a lot of CPU when its deactivated. I have the WM_ACTIVATE to start updating, but i need a notification similar to WM_DEACTIVATE. Does that even exists? Or is there another way? I couldn't find any help on Google.

What do you want to do ?

[MrAksel]

In my WndProc, i want to see if the message is the message that is sent when a window is deactivated. The WM_ACTIVATE message is sent when you activate the window, i would like to know if there was a similar WM_DEACTIVATE that is sent when the window is deactivated

[Axel]

If you mean hidden/shown with activated then you should take a look at WM_SHOWWINDOW Please don't talk in such a "wannabe pro" language I'm kinda gettin mad of it lol

For such "wannabe pro" language you should be able to see that hiding windows is not what is being asked here.

When a window is deactivated, a WM_ACTIVATE message is actually sent to both windows indicating each windows' status and the target/source window handles.

Are you using managed or unmanaged C++ code?

Here is some more documentation: http://msdn.microsoft.com/en-us/library ... S.85).aspx

I'm using unmanaged C++. If I used managed it would probably be much easier, but it depends on the .NET Framework. Thx for the link, I first tried WM_KILLFOCUS but that only fired when it lost keyboard focus, now it works perfect
