Monitoring activation of some window

How can I catch messages in my program activation or deactivation of some other program(window) ?

To catch messages that go through your application's (main thread's) message queue, you can use
Application. OnMessage
event.

To catch all other events, i beleive you should use a very sophisticated technique which i don't think you need in fact.

Event generate some other window (other application). And this event I want to catch in another (my application). onMessage doesn't work to me :o(

roupik,
This would require subclassing the other app's window (which requires injecting a .dll into that app's address space) which is highly undesirable. Perhaps you could explain, in a little more detail, what it is you need to do as there may be a better solution

Sereda, did you read the question? Did you consider giving a comment before an irrelevant answer?

Well, then it's not that simple question (for me, at least) ;)

Okay, edey, i admit my mistake -
I am sorry, roupik.
I am quite new here, and i didn't find any reasonable instructions distinguishing comments and answers.
Also i just didn't think that a complicated question involving dll injection would cost 25 pt.
Again, i apologise.
