Did you register the class?

Only in C++:

In FormCreate:

   RegisterClass( __classid( TButton ) ) ;

Adding one TButton:

   TButton* pButton ;

   rveAPP_->Clear() ;

   rveAPP_->AddNL( "Example of adding controls", 1, 1 ) ;

   rveAPP_->AddBreakEx( 3, rvbsLine, clRed ) ;

   // Adding TButton

   pButton = new TButton( (TComponent*)NULL );

   pButton->Caption = "Khang";

   pButton->Width   = 20;

   pButton->Height  = 20;

   rveAPP_->AddControlEx( "", pButton, -1, rvvaMiddle ) ;

SaveToFile:

   AnsiString sFilePath ;

   sFilePath = ExtractFilePath( Application->ExeName ) + "XML"  ;

   rvxmlAPP_->BaseFilePath = sFilePath + "\\Content" ;

   rvxmlAPP_->SaveToFile( sFilePath + "\\Test1.XML" ) ;

LoadToFile:

   AnsiString sFilePath ;

   sFilePath = ExtractFilePath( Application->ExeName ) + "XML"  ;

   rvxmlAPP_->BaseFilePath = sFilePath + "\\Content" ;

   rvxmlAPP_->LoadFromFile( sFilePath + "\\Test1.XML" ) ;

Hope that helps.

Greetings
