Instrument addition to Interface(UIR) with precompiled executable

I have a precompiled application, with a interface (.UID) file it uses. I have no interest in editing the application itself, but I with to add an instrument driver and module to output a constant from within the interface to a RS232 port.

I am unsure of whether I can proceed with my project as planned, can someone clarify on any of this?

Hi,

If I get this correctly you have an exe that loads a uir and you want to add some RS-232 communication to that application.

You could load the UIR in CVI and create a brand new application that uses the same UIR, however you will not be able to add anything to the precompiled application.

You could modify the UIR and as long as you don't change the control constants or the callbacks. However there is no way to change or add the behavior of the executable.

I hope this helps.

Regards,
