Setting Custom Caption in UI

[John242424]

I assume this should be trivial but I can't get it to work. I'm using the TestExec.exe and I'm trying to update the text of a label I've added to the Execution Tab from a step in my sequence. i.e. A step in my sequence reads a temperature and I'd like it to pass this info to the label on my TestExec UI. From the TestStand3.5 side, I tried using the PostUIMessage with a custom event code UIMsg_UserMessageBase+1 from my sequence. But, from the UI side, I can't seem to figure out how to connect to this control in my C# code to capture this message.

I've tried to use ConnectCaption but, obviously my custom message isn't one of the CaptionSource options..

this.axExecutionViewMgr.ConnectCaption(this.axLabel1, CaptionSource.? .....);

Also thought there might be a SetCaptionText function but there is no such thing I can find.

Anyone have any idea how to do this?

Figured it out....No need to do any attaching. Just simply override the  axApplicationMgr_UIMessageEvent and then check to see which user message has been passed:

 if (e.uiMsg.Event == NationalInstruments.TestStand.Interop.API.UIMessageCodes.UIMsg_UserMessageBase)

   {

my_label.Caption = e.uiMsg.StringData;

  }
