>>Hi Nick and all,

>>I noticed that many examples of drag and drop (including the one Nick you showed me of your Universal Drag and Dropper Demo Form) use the right mouse button instead of the left. Is that a MSFT standard? Should I stick to only allowing drag and drop with the right mouse button?

In addition to the previous message that I quickly typed in the Internet cafe in Paris. :)

Another reason for using the right mouse button for Drag & Drop is that: if theoretically it is possible to use the other mouse buttons (UDD class even has the .nMouseDragButton property, so you can assign left, right or middle button), then practically it does not work.

In practice, if you try to use left button for dragging, it interferes with the default Windows function of selection the text in textbox or editbox and works for dragging only for the listbox. Using middle mouse button typically interferes with the different mouse scrolling utilities.

So, the real solution is to use the Right mouse button.
