Hello again,
I guess that to vent a little bit must have helped because I was finally able to solve my problem, so you can disregard this message.
Thanks anyway: I am sure I would have had some great tips from you all.

Hi Christian, For the rest of us lurkers here, how did you solve it? Does the on-line help need clarification? Any quirks that need to be pointed out? Thanks in advance, Art Bonds
Hi Art,
Well, in the the online help under DndSource Property or DndTarget Property, at the bottom, it says:
Limits!
The DndDource and DndTarget properties can only be used with:
input controls
lists
TreeView
image controls
But, if you go under Programmed drag-and-drop, it says:
Drag-and-drop source
Only the following controls:
edit control
list
TreeView
table (listed here)
Image
Drag-and-drop target
All the types of control except:
progress bar
ActiveX
OLE
shape
I had to try it out to find out that yes, it can be used with tables. In my app, I drag from a table to a treeview, so I put "MySelf..DndSource = dndProgram" in the table's initialization event, and "MySelf..DndTarget = dndProgram" in the treeview's initialization event. Also, in the treeview initialization, I put "DnDEvent("dndTreeViewDrop", MySelf, dndDrop)", where as "dndTreeViewDrop" is the procedure executed when the item is dropped in the treeview. That's it!
My only other problem is that it doesn't drop it where I want in the treeview. Again, the help provided with Windev is inexistent, so as above-mentioned, I will solve it on my own. I found a post regarding this in the forum's archive, but it doesn't work for me.
Thanks,
Christian |
