Pleas take not that GetSafeHwnd will return a valid handle only after OnCreate for the base class has been called.


<div>
I can only see the following OnCreate statement in the entire project:<br />
<br />
int CMainFrame::OnCreate(LPCRE<wbr />ATESTRUCT lpCreateStruct)<br />
{<br />
&nbsp; &nbsp;:<br />
}<br />
<br />
Is this the correct place to insert the GetSafeHwnd() statement?<br />
<br />
And BTW, your help really is appreciated.<br />

Hi,<br />
<br />
HELP!! I am new to MFC programming and I'm really struggling with what seems like a really simple problem.<br />
<br />
Ok, I have created an application using AppWizard. I have now started adding functionality to the application (the app will control a TWAIN complient scanner, and perform some image processing techniques). The code that is supplied with the TWAIN SDK uses the handle to window value (hwnd). The problem I have is obtaining this value when using MFC. I have tried everything I can think of, and desperately need some help.<br />
<br />
I have tried: CWnd m_hWnd - no luck. I can't get FindWindow to work either.<br />
<br />
Any help would be greatly appreciated.<br />
Thanks,<br />
