Get Ready to Unleash the Power of UCanCode .NET

The idea is to create a callback function that is passed to Win32 API function ::EnumChildWindows(). Somewhere in the application, global CFont object is created. Pointer to this object is passed as a third argument in EnumChildWindows(). This argument is passed to a callback function together with a handle to a child window. Using these 2 arguments, the function changes the font for the child window.

Using this technique, it is very easy to:

• Change the font for main frame window, its child views and a status bar from CMainFrame::OnCreate().
• Change the font for all dialog controls from OnInitDialog().

The Callback function looks like this:

Collapse Copy Code

// lParam is a pointer to CFont object
BOOL __stdcall SetChildFont(HWND hwnd, LPARAM lparam)
{
   CFont *pFont = (CFont*)lparam;
   CWnd *pWnd = CWnd::FromHandle(hwnd);
   pWnd->SetFont(pFont);
   return TRUE;
}

This callback function is used from OnCreate() or OnInitDialog() in the following way:

Collapse Copy Code

...
// g_Font is an object of type CFont or derived from CFont
EnumChildWindows(m_hWnd, ::SetChildFont, &g_Font);
...

Load cursor from resource:
//
// LoadAnimatedCursor: Loads an animated gif from the resource as an cursor
//
HCURSOR LoadAniCursor(UINT nID)
{
	HINSTANCE hInst=AfxGetInstanceHandle();
	HRSRC hRes=FindResource(hInst,MAKEINTRESOURCE(nID),"ANICURSORS");
	DWORD dwSize=SizeofResource(hInst, hRes);
	HGLOBAL hGlob=LoadResource(hInst, hRes);
	LPBYTE pBytes=(LPBYTE)LockResource(hGlob); 
	return (HCURSOR)CreateIconFromResource(pBytes,dwSize,FALSE,0x00030000);
}
