In plain VB there is no way to determine or change the height of node elements in a TreeView control. All you need to accomplish both tasks, however, is send the right message to the control. Click here to copy the following block Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal _   hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, _   lParam As Any) As Long Private Const TV_FIRST = &H1100 Private Const TVM_SETITEMHEIGHT = (TV_FIRST + 27) Private Const TVM_GETITEMHEIGHT = (TV_FIRST + 28) ' return the height of a TreeView's individual items NodeHeight = SendMessage(TreeView1.hWnd, TVM_GETITEMHEIGHT, 0, ByVal 0&) ' set the height of a TreeView's individual items ' use the value -1 to restore default height SendMessage TreeView1.hWnd, TVM_SETITEMHEIGHT, newNodeHeight, ByVal 0&
