Changing icon in MDI child window

I need to change the icon on each MDI child window under VC4.2, MFC. The icon can be changed when the child window is created or at runtime. I've searched for solutions and the best found is the following:

CMyApp* pApp = (CMyApp*)AfxGetApp();
ASSERT (pApp!=NULL);
HICON m_Icon;
repIC = pApp->LoadIcon(IDI_REPLY);
<Picture>SetIcon(m_Icon,FALSE);

This only changed the icon of the program's main (or mainframe) caption, but not the child window (or childframe). I then changed it to this, also to no avail:

CMyApp* pApp = (CMyApp*)AfxGetApp();
ASSERT (pApp!=NULL);
HICON m_Icon;
repIC = pApp->LoadIcon(IDI_REPLY);
((CMDIFrameWnd*)
(AfxGetApp()->m_pMainWnd))->MDIGetActive()->SetIcon(m_Icon,FALSE);

Many thanks in advance for your help!

Hi

Code that you are having is correct as far as changing the Icon is concerned.
Try it from your View object

Since you may have to change icon more than once, best way is to define
it in a function and call it.

From the View, access the MDIChildWnd or ChildFrame by a call to
GetParent, assert on the Kindof Window and proceed with LoadIcon/SetIcon
exactly the same way as before

If you are changing icons on activation /deactivation of the View or Frame
override View classes  
OnActivateView and/or OnActivateFrame


Bye


Try this from other way around

Hi Sam,

Indeed, from the childframe (i.e. ActivateFrame) it works. It doesn't work from the mainframe. The view is more complex for this app.

Thanks!
