An AV occurs when closing an application with a statically linked DLL file that contains one or more DevExpress controls if the native painting style is applied

created 12 years ago

When using dxBar Components from a form in a Dll, an AV occurs when unloading the Dll.

Delphi
function CloseThemeData(hTheme: TdxTheme): HRESULT;  
begin  
  Result := FThemeLibraryMethodPointersKeeper.FCloseThemeData(hTheme);  
end;

    Hello,
    Most of our controls use the GDI+ Library. It seems that this problem is related to the incorrect initialization of this library.
    Please review the following reports, which contain helpful information:
    GDI+ problem in a COM library
    AV in DLL using dxRibbon
    Access Violation using TcxImageList in DLL (64-bit Windows)
    Note that the dxInitializeGDIPlus and dxFinalizeGDIPlus functions have been moved to the dxCore unit. They were renamed to dxInitialize and dxFinalize respectively.
    If this does not help you, please provide us with a sample project that illustrates this issue. We will test it and do our best to find an acceptable solution for you.
