virtual L_BOOL LBitmapRgn::IsValid()
Determines whether the region object is valid.
|TRUE||The region object is ready to be used.|
|FALSE||The region object is not ready to be used.|
Before you can use any of the region functions, a bitmap must be associated with the class object. Until you have associated a bitmap with the LBitmapRgn object, the object is considered invalid.
For an example, refer to LBitmapRgn::SetRgnEllipse.
