Problems to use TElTreeStringGrid And DLL

sirlordt

I develop a dll with the form and TElTreeStringGrid, cannot use never freelibrary, because the program freeze to end, 100% CPU used, i used C++ Builder XE Update 3.

  UnicodeString strFilePath = ExtractFilePath( Application->ExeName ) + "CGuestDLL.dll";

  CGuestDLLHandle = LoadLibraryW( strFilePath.c_str() );

  if ( CGuestDLLHandle != 0 ) {

     TFunction_showform ShowForm = (TFunction_showform)GetProcAddress( CGuestDLLHandle, "ShowForm" );

     ShowForm();

     FreeLibrary( CGuestDLLHandle ); //<---- Cannot use the program freeze to unload/end 100% CPU Used

  }
  else {

     Application->MessageBoxW( L"Fail", L"Fail", MB_OK );

  };

My DLL Show Form is the next

__declspec (dllexport) void __stdcall ShowForm( void ) {

  TfrmGrid  *frmGrid;

  Application->CreateForm( __classid( TfrmGrid ), &frmGrid );

  frmGrid->ShowModal();

  delete frmGrid;

}

For test propuses frmGrid Is Only TElTreeStringGrid no buttons nothing, Try with TElTree and same result.

Sorry For the bad english.

Problem Solved in C++ Builder XE Update 3

//Add the lines to end of delete frmGrid;
//Clear LMD theme services globals vars

 TLMDThemeServices *_LMDThemeServices = LMDThemeServices();

  delete _LMDThemeServices;

  TThemeServices *_ThemeServices = ThemeServices();

  delete _ThemeServices;

Hi,

If it is not crucial to call      FreeLibrary( CGuestDLLHandle );  right after ShowForm();

then you might move FreeLibrary( CGuestDLLHandle ) call to finalization part, this change must remove issue, too.
