When using Delphi XE2 or above editions to compile coeds likes below:
|
1 2 3 4 5 |
procedure VEMRCREATEBRUSHINDIRECT(Data: PEMRCreateBrushIndirect); begin GDIObjects[Data^.ihBrush] := CreateBrushIndirect(Data^.lb); //GDIObjects and CreateBrushIndirect are defined in the winapi.windows unit. end; |
The compiler says: E2010 Incompatible types: ‘tagLOGBRUSH’ and ‘tagLOGBRUSH32’. The solution to fix this compiling error is:
|
1 2 3 4 5 6 7 8 9 |
procedure VEMRCREATEBRUSHINDIRECT(Data: PEMRCreateBrushIndirect); var LogBrush: TLogBrush; begin LogBrush.lbStyle := Data^.lb.lbStyle; LogBrush.lbColor := Data^.lb.lbColor; LogBrush.lbHatch := Data^.lb.lbHatch; GDIObjects[Data^.ihBrush] := CreateBrushIndirect(LogBrush); end; |
This example shows you how to programmatically New and Free a HotPDF object instance with C++Builder.
