// Function Name: AddTaskFolderText
// 
// Purpose: Reads and adds existing POOM tasks to the main listbox
//
// Arguments:
//    IN IPOutlookItemCollection * pItenCol - ptr to the Tasks default folder
//		collection interface
//
// Return Values:
//    Describes the return type an meaning of each value.  E.g.:
//    BOOL
//    returns TRUE if the item was successfully read and added. Otherwise FALSE
// 
// Description:  
//   This function iterates through the collection of tasks, reading 
//		properties from each. The string data is then added to the main 
//		listview control
