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.

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal _    hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, _    lParam As Any) As LongPrivate Const TV_FIRST = &H1100Private Const TVM_SETITEMHEIGHT = (TV_FIRST + 27)Private Const TVM_GETITEMHEIGHT = (TV_FIRST + 28)' return the height of a TreeView's individual itemsNodeHeight = SendMessage(TreeView1.hWnd, TVM_GETITEMHEIGHT, 0, ByVal 0&)' set the height of a TreeView's individual items' use the value -1 to restore default heightSendMessage TreeView1.hWnd, TVM_SETITEMHEIGHT, newNodeHeight, ByVal 0&
