check VI type for call by reference node

[lordsathish]

Hi Ppl,

I'm calling a set of VI's dynamically using call by reference node. And I have a type specifier linked to a particular type connector pane. But at times when the VI prototypes do not math I get error from the open VI reference node. Is there any way to check if the VI connector panes matches before opening the refrence with the VI type specifier ?, or using the error code is the only way to check if there were miss match in VI connector pane.

Thanks

But what is wrong with Error checking?

For example, I using code like this in my application for detect which type of dynamic VI should be used (decision based on Error output):

Ok Andrey,

I will then check the error to check the VI type.

Thanks
