I have a MDI form and a child form with a Rich text box in it.  I would like to be able to drag a file into the empty space of the MDI form and open the text file in the Rich text control.

How do I open a text file by dragging the icon into my MDI form?

Any Ideas?

TigerZhao: Yes, it's possible to subclass MDIForm and loop for WM_DROPFILES message. If you want to study subclassing and use only pure API code, it's OK. But if you need simple code - VB itself already have _OLEDrag... events. Place your code at these events and you need no subclassing. It's the same if you want to subclass window or control to loop for WM_LBUTTONDOWN instead of using appropriate event for this form/control
