How can I read properties of custom controls?

[Steve_Block]

This looks like something I might be able to use, but how can I do this in CVI?

Hi Steve,

To do this in CVI you have to implement SDK. How to do this take a look in your CVI help and search for Windows SDK

The library you need is kernel32.lib

Also take a look to MSDN help at: http://msdn2.microsoft.com/en-us/library/aa366537.aspx

Hey Steve,

I also wanted to give you a link to some sample CVI code that uses the UIMessage function to pass messages between TestStand and the Operator Interface.  You can find "LabWindows/CVI Simple Operator Interface with Yield Information" at http://zone.ni.com/devzone/cda/epd/p/id/3550.  You can also find another example using the UImessage callback at “How to Work with UIMessages in TestStand 3.0” (http://zone.ni.com/devzone/cda/epd/p/id/3879).   For this example, please refer to line 168 in TestExec.c.  Remember that UImessage event codes from 1 to 9999 are reserved for TestStand, but 10000 and beyond are user definable (UIMsg_UserMessageBase = 10000).  Please see “Using Default and Custom UIMessages” at http://zone.ni.com/devzone/cda/tut/p/id/4532 to view a refresher on how to make a TestStand Step send a user-defined UImessage event.  I hope this helps!
