Despite this is the nativeapi group, you could try
this VCL solution:

#include <memory>

void capture( AnsiString FileName )
{
    const TRect Rect( 
        0, 0, Screen->DesktopRect.Width(), Screen->DesktopRect.Height()
    );
    std::auto_ptr<Graphics::TBitmap> Bmp( new Graphics::TBitmap );
    std::auto_ptr<TCanvas> Cnvs( new TCanvas );
    Bmp->Width = Rect.Width();
    Bmp->Height = Rect.Height();
    Cnvs->Handle = GetDC( 0 );
    Bmp->Canvas->CopyRect( Rect, Cnvs.get(), Rect );
    Bmp->SaveToFile( FileName );
}
