I want to assign an icon 32x32 to a property sheet. The property sheet is the main window of the application. I am using VC++4.2 on NT4.0.
I defined the following:
class CAdSheet : public CPropertySheet
...
CAdSheet addlg();
m_pMainWnd = &addlg;
HICON secIcon = AfxGetApp()->LoadIcon(IDI_
HWND hWndParent = (HWND)this;
SendMessage(hWndParent,WM_
addlg.m_psh.dwFlags |= PSH_USEHICON;
addlg.m_psh.hIcon = secIcon;
nResponse = addlg.DoModal();
...
The icon IDI_MAINICO is assigned to my property sheet. It appears in the upper left of the window, in the taskbar and in the Explorer as both small and large icons. But, when I use Alt-Tab, the icon is the Windows flag. I would like to have the IDI_MAINICO appear when I Alt-Tab. Is there a way to do this or is this the only way a dialog can appear in that situation?

Pardon the 'F'. I placed the code in the CAdSheet class, but I am still getting the Windows Flag when I Alt-Tab. CAdSheet is a class defined in CAdSheet.h and .cpp and included in the main program. The code above is called in the InitInstance function of the main program. The class in the main program is: "class CSecAdminApp : public CWinApp". I appreciated your earlier response. Thanks.
You can use SetIcon is an MFC 4.0 wrapper for SendMessage(WM_SETICON...)
BOOL CMyDialog::OnInitDialog()
{
SetIcon(AfxGetApp()->LoadI
FALSE);
SetIcon(AfxGetApp()->LoadI
TRUE);
return CDialog::OnInitDialog();
}
You can find a good sample in MSJ 1996 April in section "C/C++ Q&A"

Handle WM_PAINT message in like this:
void CAdSheet::OnPaint()
{
if( IsIconic() )
{
CPaintDC dc(this);
SendMessage(WM_ICONERASEBK
// Center icon in client rectangle
int cxIcon = GetSystemMetrics(SM_CXICON
int cyIcon = GetSystemMetrics(SM_CYICON
CRect rect;
GetClientRect(&rect);
int x = (rect.Width() - cxIcon + 1) / 2;
int y = (rect.Height() - cyIcon + 1) / 2;
dc.DrawIcon(x, y, m_hIcon);
}
else CDialog::OnPaint();
}
This is a fragment from dialog based application created by AppWizard.
