Hi Experts,

I'm new to C++ and finding most things a lot harder than vb.net.

I have a clock duration in variable tDuration of type clock_t and I’ve build a plain win32 application and created a hdcWindow that I’m drawing to using GDI+.

                   clock_t tDuration = clock() - tStart;
              
              Font drawFont(L"Arial", 16);
              RectF layoutRect(0.0f, 0.0f, 200.0f, 50.0f);
              StringFormat format;
              format.SetAlignment(StringAlignmentCenter);
              SolidBrush drawBrush( Color::Black );

                  graphics.DrawString(tDuration, 11, &drawFont, layoutRect, &format, &drawBrush);

I get an error when this code runs because the graphics.DrawString wants to convert the tDuration (see error below).  

So can someone give me some code that shows me how to get the variable tDuration into a string format that DrawString can use?

Error      1      error C2664: 'Gdiplus::Status Gdiplus::Graphics::DrawString(const WCHAR *,INT,const Gdiplus::Font *,const Gdiplus::RectF &,const Gdiplus::StringFormat *,const Gdiplus::Brush *)' : cannot convert parameter 1 from 'clock_t' to 'const WCHAR *'
