Program Startup - WM_OnSize message

[Athlon1600]

in my OnSize message handler, I have this code:

	m_WebBrowser1.put_Width(cx);
	m_WebBrowser1.put_Height(cy);

^ it resizes the WebBrowser control in a way that it takes up the whole dialog window.
If user resizes a window, webbrowser changes its size as well.


Here is the problem: when the program starts, I get 2 exactly the same errors:

DEBUG ASSERTION FAILED
winocc.cpp... line 373.....


I'm able to hit ignore twice and then the program runs normally, but why do I get these errors?

My guess is that I'm trying to use m_WebBrowser1 variable before it is declared. I could be wrong.


How would I fix it?

Did you notice the button that says click retry to debug?

[Athlon1600]

yes, if I were to hit retry, the message goes away.

but why does the message appear? where is the problem?

The assertion is probably because the web browser window has not been initialized.
I don't remember if the web browser control has a m_hWnd member, but you could try this.

if (::IsWindow(m_WebBrowser1.m_hWnd)
{
    m_WebBrowser1.put_Width(cx);
    m_WebBrowser1.put_Height(cy);
}

yup, the ::IsWindow check solved the problem

Thanks for help
