Conditional load of DLL -- error check

[cosborne]

I'm new to using external code in LabView so I might be missing something obvious.

Is there a way to check for the presence of a DLL before making the call? How can you avoid an error (or catch the error) when a DLL is missing? The "Call Library Function Node" doesn't seem to have any way of handling the error.

I'm using LV7.0

Hi cosborne,

you can place the dll call into a vi. If you load this vi dynamically, then you can check the presence of the dll before you try to load it.

Mike could you please elaborate it? Give some bit more details about checking the presence of the dll.

Thanks,
