PBM_WINDOWPOSCHANGING

[Former Member]

Hello all!

After searching MSDN and other sources for too large a fraction of an hour, I've come up dry trying to find the absolute values needed for flags/messages for WM_WINDOWPOSCHANGING to influence window behavior in various ways.

The MSDN pages for teh event have almost no detail for usage let alone a roster of values and/or links to the specs for the structures used.

Anyone know of a source for these values/definitions?

Thank you.

I found a page for details about the structure involved here:

WINDOWPOS structure (Windows)

And a blog article on how to use it here:

Thanks!

I had been looking at SWP_NOMOVE, but I'm intrigued by the possible nuclear option of SWP_NOSENDCHANGING.

Hi John;

   A very interesting question John!

   Can I ask you the inverse of your question ... Exactly, what are you trying to accomplish? Maybe this is not the optimal feature to be using. However, it might be and knowing the application might help our readers understand why you would be looking into this Windows Message.

Regards ... Chris
