SYMPTOMS

In the original version of Win32, there is no IsGdiObject() function in the Win32 API. However, the new function GetObjectType can be used as a replacement for IsGDIObject.

The changes apply to Windows 95 and Windows NT 4.0.


CAUSE

The Windows 3.1 IsGDIObject function has been enhanced and renamed to GetObjectType. In addition to verifying that an object handle refers to a GDI object, GetObjectType also returns a value that describes what kind of object the handle represents.


RESOLUTION

You can use the following macro to aid in porting your programs that were originally designed for Windows 3.1:


   #define IsGDIObject(hobj) ((BOOL)GetObjectType(hobj)) 


STATUS

This behavior is by design.
