how to display vi ,when vc calls labview dll

[sarali]

i'm sincerely sorry to reply so late ,

i'm sure the VI program is running correctly, and what do you meaning by adding VIs,and which module are they in,would you please explain it in detail,thank you.

I believe what Scott was suggesting was that you add some kind of code to verify that the DLL is actually running in the background. He specifically suggested adding code to write to a file, but you could do any number of things. I think a better idea would be to display a dialog at the beginning and end of your VI's execution (the One Button Dialog VI is located in the All Functions>>Time & Dialog palette). It could be quite possible that your code executes so quickly that you don't have a chance to see the front panel, and adding dialogs will let you know when the VI starts and stops, and thus how long the front panel should be showing.

Kind Regards,

i do a experiment to test if the dll is actually running by using Call Library Function Node,and it runs correctly,when i start the test vi,it calls the dll,and shows the vi that i build the dll. So,i think the dll is right.

Further,i will do the experiment that you suggested above, and i guess you mean whether i should wait some time or,the dll needs some time to be loaded,am i right?

thanks for your suggestion.
