Resize of parent control

[Val]

I am trying to create my own ActiveX control and I need this control behaves
depending on current size of parent control. How can I define in my ActiveX
control if parent control has changed its size?

Thanks for any help

You'll need to hook the message stream of the parent, and watch for relevent window
messages (WM_SIZE, WM_SIZING, etc.) If you're unfamiliar with this technique, see
HookMe.zip or Grabber.zip on my web site.

Hi Karl

How can i define if my control has changed his position?
Can I use same technique like in HookMe?

Thanks

Well, it'd take some testing, but I would imagine you'd be watching for WM_MOVE or
WM_MOVING on your own control, yeah. Make sense? Do you have Spy++ installed?
That's the quick/easy way to figure out what messages to watch for.

Hi Karl,

Every time when I try to set hook inside my control VB crashes. I also tried
to use dwspydmo.dll, which provides same technique but I got same result.
Maybe I do it in wrong way?

Thanks for any help.

Yep. Not sure what else to say. There are literally hundreds, if not thousands, of
examples on the net. Without you offering more clues than to say "VB crashes", all I
can do is agree.

Hi Karl!

I made hook inside my user defined control using SetWindowsHooEx API function.
If I use WH_CBT type of hook procedure it works fine, but if I try to use
WH_CALLWNDPROCRET type, my VB crashes immediately and it seems to me that
my hooking procedure looping. Can I use WH_CALLWNDPROCRET type inside my
user defined control?

Thanks,

Val

It works fine unless I try to use

Hi Val --

Well, I'm lost, now. I thought you were interested in the sizing of the *parent* to
your UC? Seems this direction would be for looking at children of your UC, no?

Sorry... Karl

Hi Karl!

I am trying to fit my UC to size of parent control (Form or picture box)
and I need to track size changing of parent control.

Thanks,

Val

Hi Val --

We're going in circles here, then. <g> Go back to the beginning, where I talked
about hooking the message stream for the parent. You're not in need of a CBT hook.
