SUMMARY
How do you disable the dropping of files in RichEdit version 2.0 with the
CRichEditCtrl class?
Call the RevokeDragDrop(), passing the pointer to the RichEdit control
window, as the parameter. Also, override the OnDropFiles() and return
without calling the function of the base class.
MORE INFORMATION
To prevent a Drag-and-Drop enabled window from accepting files use the
RevokeDragDrop() function. Pass the pointer to the target window as the
parameter for the function. The WM_DROPFILES message handler must be
overriden and control must be returned from it, without calling the
OnDropFiles() function of the base class.
You use this function during the initialization, typically, in the
InitInstance() function of the window procedure. Handling the WM_DROPFILES
message alone, or calling only the RevokeDragDrop() is not sufficient. To
successfully prevent the links from being placed in the RichEdit control
version 2.0, you must do both of the previously mentioned steps.
