Retrieve a SysTreeView Controls Selected Text

 Keywords:  get grab SysTreeView32 Selected Item Text

QUESTION:

Hello, Is there any way to find the value of a node in a SysTreeView32 control? There are ways to set the node (cSetTVItem) that gets focus but what I want to do is copy the label text from the tree item and place it on the clipboard to use later...

Any thoughts

ANSWER:

Do you need to get the selected item text?

if so you can try this fuction , use the ctrl mngr extender to get the treeview handle.
