get pszText of a selected TreeViewItem

[Uwe Vogt]

Hi,
I need to get the displayed Text of a selected TreeViewItem:

I got the handle of a TreeViewItem:

 'get handle of the selected item
hItem&=TreeView_GetSelection(hTreeView&)

->that works!

but how can I get the pszText (of the Item) now?

Hi Uwe,

This returns the text for a tree item having handle hItem -

function TVW_GetText( byval hTree as long, byval hItem as long ) as string

  'Purpose : Returns the item's text ; if the item is not found, returns ""
  '
  'Remarks : Allows max of 255 characters for tree item text
  '
  local ti      as TV_ITEM
  local zText   as asciiz * 256
  local s       as string
  
  'Set up the tree item structure for our purpose...
  ti.hItem      = hItem                              
  ti.mask       = %TVIF_TEXT                                  
  zText         = space$( 255 )                       
  ti.cchTextMax = 256                                
  ti.pszText    = varptr( zText )                                   

  'Query the tree...
  if TreeView_GetItem( hTree, ti ) = 0 then        'call failed             
    function = ""
  else
    s = zText
    function = s
  end if

end function

A book I've found really useful is Windows 95 Common Controls & Messages API Bible,
by Richard J Simon, ISBN 1-57169-010-7. Also, you can download the free TinyHelp
project from my web site which contains lots of useful treeview code.

Regards,

Paul
