Hi

With regards to my problem, what happens if clone method is used instaed if event structure. Because i have seen the clone example and it seems bit easier.

Thanks

[Veeru]

The example i have seen is reentrants program in the NI examples

Something doesn't make sense. Calling a subVI is extremely basic and is covered in basic tutorials that you should take. You keep mentioning things like dynamic calls, clones, reentrant and those are used for certain special applications and from what you have asked for so far, not at all necessary. You might want to explain in some detail why you are looking at those things. Are these subVIs all the same? Do you want the subVIs to all be open at the same time?

Apologize dennis,this is the 1st time i am using this SubVi and calling into main prgs.

Now i got it after reading the materials.

Also i got a question,I called the subvi through the call Vi reference into the event structure of main program,after executing it gives the error message 1000,what it means

[Dennis_Knutson]

The error means 'The VI is not in a state compatible with this operation.'

I have no idea why you are using the Call by VI Reference and unless you post the main VI and subVI, no one can tell what you have done wrong (aside from making things much more complicated than it needs to be).

Actually,i have to run many applications(for ex:5), from my main program i can choose which application needs to run.so if i choose application2 then its corresponding front panel should open so that i can see the results.

sorry if anything is wrong becoz just i am learning and developing prgs.

Thanks

Thanks Dennis

I have attached the prgm

[Dennis_Knutson]

This would be the normal way to call a subVI.

As far as your example, as the help says, if you wire up to the type specifier input, you cannot use the Run VI method. Delete it and it will work.

Thanks Dennis

But after the selection of 1st application,the sub vi front opens and running but the main vi finishes
