I'm trying to render a CPictureHolder image onto a dialog.  I've posted my code below, but it's not working.

CPictureHolderEx      pic;
      CDC                              *dc;
      CRect                        crClient;
      CRect                        crPic;
      CStatic                        *frame;


      frame = (CStatic*)this->GetDlgItem(IDC_FRAME);
      frame->GetWindowRect(&crPic);
      GetClientRect(&crClient);
      GetClientRect(&crPic);
      pic.OleLoadPictureFromFile("c:\\test.jpg");
      dc = this->GetDC();
      pic.Render(dc,crPic,crClient);

On dialog?
You need to do the rendering in the OnPaint else it is 'removed' by the default OnPaint which will cover the client area by the background colour.  (Load it in OnInitDialog - that is just called once).

Also put your CPictureHolderEx object as a dialog member (in .h)
Put this sentence in the OnInitDialog() function as recommended by Andy:      pic.OleLoadPictureFromFile("c:\\test.jpg");
Put the rest of code in the OnPaint Event.
