GetClassInfoEx
The GetClassInfoEx function retrieves information about a window class, including the handle of
the small icon associated with the window class. The GetClassInfo function does not retrieve the handle of the small icon.
BOOL GetClassInfoEx(
HINSTANCE hinst,
| // handle of application instance
| LPCTSTR lpszClass,
| // address of class name string
| LPWNDCLASSEX lpwcx
| // address of structure for class data
| );
|
|
Parameters
hinst
Identifies the instance of the application that created the class. To retrieve
information about classes defined by Windows (such as buttons or list boxes),
set this parameter to NULL.
lpszClass
Points to a null-terminated string containing the class name. The name must be
that of a preregistered class or a class registered by a previous call to the RegisterClass function. Alternatively, this parameter can be an integer atom. If this
parameter is an integer atom, it must be a global atom created by a previous call to
the GlobalAddAtom function. The atom, a 16-bit value less than 0xC000, must be in the low-order
word of lpszClass; the high-order word must be zero.
lpwcx
Points to a WNDCLASSEX structure that receives the information about the class.
Return Values
If the function finds a matching class and successfully copies the data, the
return value is nonzero.
If the function does not find a matching class and successfully copy the data,
the return value is zero. To get extended error information, call GetLastError.
