Examples
The following examples show three ways in which WoAddMessage can be used in a VDA Tool. Messages are defined in a resource file, and WoMessage is used to create the message area in the VDA Tool.
This is part of a resource file defined for a VDA Tool.
mytool.ads
MyTool_intro: Welcome to my tool...
MyTool_SelectButton_1: Press MB1 to begin selection
MyTool_SelectButton_2: Press MB2 to end selection
MyTool_FileRead: Reading file: 
...
; Create a 6 line message area.
...
ms = WoMessage(layout, tool_name, Rows=6, /Frame, /Left, $
   /Right, /Bottom)
Example 1
Introductory messages are added to the VDA Tool.
WoAddMessage, tool_name, 'MyTool_intro', /Clear
WoAddMessage, tool_name, 'WzGlobal_intro'
Example 2
WoAddMessage can display multiple messages with a single call.
WoAddMessage, tool_name, 'MyTool_SelectButton', /Clear
Example 3
Messages can be tailored with dynamic information and then displayed.
msg = TmGetMessage('mytool.ads', 'MyTool_FileRead')
msg = msg + ' ' + file_name
WoAddMessage, tool_name, Message=msg
