Anyone had error before ?

Multiple instance of an exe launched.  Inside the exe, server port and name changed (and verified) using property node, so I can distingush the 2 instance.

In LabVIEW (or another exe), when use the updated server name to open applicaton reference, first one works fine, but not working for the 2nd instance, get error 1510.

LabVIEW 2011 64 bit, on Win7.

Hi George,

I just wanted to add some context here about what we've discussed offline. This error is happening when opening an Application reference to the second instance of an executable running on the same machine as the LabVIEW Dev environment.

The Open App Reference works fine for one instance but gets this error on the call to the second app instance. We have set the port number and service name of each instance to different values in the ini file and with property nodes; confirmed this with indicators on each exe.

Thanks!

Problem solved.

Simply use 337x, or 338x for port #.

For some reason 336x is no good for multiple instance of an exe.  No error / warning from LabVIEW.

HI George:

 I have met the same problem with you, can you tell me how to solve it?

Thanks

Are you using property node to change the server settings?

I run multiple instances of the same exe.  That's why I have to change the settings programmatically.

Need change both the server name and the port #.
