Hi,
a solution i have used is the "PostUIMessage TestStand ActiveX function", using the users codes (>= 10000).
In the "exedisp.c" source file, add a custom function like "UIMsgAddReportText" witch update the report panel ED_REPORT in the CVI Operator interface.
Customize the "UIMessageDeferredCallback" function in the "engine.c" source file to add a switch case
"case TS_UIMsg_UserMessageBase + 1:" witch calls the function "UIMsgAddReportText".
I hope this will help you.
Best regards
JMC
