The same thing is happening too me...... everything build fine in Labview but when it is run I get a ntdll.dll error....

Very very sad... The link provided above is for labview 10.... can anyone provide a 2009 version? Thanks Do you reckon you could make it exist? and if not why not? Thanks Tim

So it could be a bug in Labview?

Hi, I am thinking about writing an application that will grab user events from an executable that it connects to via VI server, stores the events (and the initial states) and then replays them on command. I was just fooling around, I discovered I can read and write to controls on the running executable but when it comes to registering user events I get Error 1055 occurred at Register For Events in Test.vi Possible reason(s): LabVIEW: Object reference is invalid From the attachement it can be seen that the error occurs when you try and register a user event. Is this a security issue which causes this limitation? Is there a way around it? Thanks, Tim

Thank you all for the very speedy replies, most appreciative and helpful!

Hi, Just wondering if anyone knows anything about capturing events so that they can be replayed in the correct sequence and time order. So that it will replay the application in the exact same way the previous user used the application (No text input, just clicks representing touch screen user input). Thanks Tim
