Creating SysTreeView32 dialog

[Lucas]

Can you help to create a dialog with SysTreeView32, Button and Edit: to insert edit text to SysTreeView32 as son of selected item in SysTreeView32.
Finally convert SysTreeView32 to text.

Thanks in advance.

I used XML format to save tree view control data.

FUNCTIONS:
dialog_treeview_xml
XmlToTreeView
XmlFromTreeView

;Gets tree view control items to tab-indented string.

;s - variable that receives string.
;htv - control handle.
;htvi - parent item handle. Can be 0.
;__indent - don't use.


if(!__indent) s.all
htvi=SendMessage(htv TVM_GETNEXTITEM iif(htvi TVGN_CHILD TVGN_ROOT) htvi)
rep
,if(!htvi) break
