Question

How would I drag and drop something into a static control? It looks like I need to create a sub class of COleDropTarget and include that as a member variable in a custom CStatic. That doesn’t appear to be working though. When I try and drag something onto the Static control I get the drop denied cursor.

Answer 1

The static control’s m_hWnd must be valid when you call COleDropTarget::Register, which is why it doesn’t work from within your CMyStatic constructor. What you can do is override CWnd::PreSubclassWindow within your CMyStatic class:

class CMyStatic : public CStatic {     ...     virtual void PreSubclassWindow(); };  void CMyStatic::PreSubclassWindow() {     CStatic::PreSubclassWindow();      m_MyDropTarget.Register(this); } 

There’s a really good article here on CodeProject that you may find helpful.
