First of all, we can read perfectly normal font. There's no need to use size 18 bold red font.

Use the FileOpenDialog class this way:
OpenFileDialog *opfdlg=new OpenFileDialog ();
opfdlg->Filter="JPEG files (*.jpg;*.jpeg)|*.jpg;*.jpeg";
opfdlg->ShowDialog()

To show the image, use:
String *s=opfdlg->FileName;
m_bitmap=new Bitmap(s);
Invalidate();

Use the OnPaint handler this way:
Graphics *g=e->Graphics;
g->DrawImage(m_bitmap,this->AutoScrollPosition.X, this->AutoScrollPosition.Y, m_bitmap->Width,m_bitmap->Height);

That's it. You're done.

I had been using OnFileopen(), But you have mentioned OpenFileDialog how should I use that class?[/b]
