Public Function GetTreeData(formID As String, TreeName As String, prop_Id As ENUM_GUI_TREE_DATA, ByRef prop_Value As String, Optional Index As Integer = 1) As Boolean

This function is used to get node count for a specific tree (GUI control).


Key  Description 
formID Form identifier, must be a number greater than 3000 and less than 10,000
TreeName Tree identifier, value of type String.
prob_Id porperty to get its value. Value can be one of the ENUM_GUI_TREE_DATA
prob_Value To hold the returned value, value of type String
Index The index of tree node, Optional value of type Integer.

Return value

Returns true if the GUI control (tree) data has been returned to the specified property. Otherwise, returns false. In order to get an error, call GetLastError() function
