using the __wm_notify function

[bab]

I admit that I do not understand the _wm_notify function. I created a treeview menu for server documentation:

+Server1

+backup

-filename

+baseline

-filename

+configuration

-filename

+Server2

+backup

-filename

+baseline

-filename

+configuration

-filename

+Server3

+backup

-filename

+baseline

-filename

+configuration

-filename

I only want the function to respond to a double click on the filenames. Any help would be greatly appreciated. Thank You.

If you only want double-clicks, why select for $iCode = $NM_CLICK instead of $NM_DBLCLK?

After that, you have to see which item was clicked on, then determine if it was a "filename" type or not. The TreeView control doesn't know the difference, so you'll have to figure that out for yourself.

On receiving WM_NOTIFY from the TreeView's Hwnd, and with a Code of NM_DBLCLK, you want to get the handle of the selected item and see if that item is in you list of "filenames" or not.
