GetClassInfo
The GetClassInfo function retrieves information about a window class.
The GetClassInfo function has been superseded by the GetClassInfoEx function. You can still use GetClassInfo, however, if you do not need information about the class small icon.
BOOL GetClassInfo(
HINSTANCE hInstance,
| // handle of application instance
| LPCTSTR lpClassName,
| // address of class name string
| LPWNDCLASS lpWndClass
| // address of structure for class data
| );
|
|
Parameters
hInstance
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.
lpClassName
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 so, 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 lpClassName; the high-order word must be zero.
lpWndClass
Points to a WNDCLASS 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 fails, the return value is zero. To get extended error
information, call GetLastError.
