find the missing instrument driver

[L_K]

I am new to C++ and happened to modify someone else's VC++ code. That code interfaces with Spectrum analyzer, signal generator, motion controller. That code originally runs on Windows NT but I have to transfer it to Windows XP. So I compile the program on XP computer and got an error says "undeclared identifier: ID_instrument_select_spectrumanalyzerrsfsek" Is it because I miss one of the instrument drivers? if so, how do I find which instrument driver I am missing, and once I find that out, how do I make the code see that instrument driver?

It would be difficult to pinpoint this exactly without seeing your code and project files, but I do not believe this error is because of a missing instrument driver. Were you modifying User interface code when you encountered this error? That identifier looks like it was possibly the ID value for some UI element. Can you determine from the context in which it's being used what the constant is for?

Incidently, was there a specific problem with the existing codebase such that it worked on NT but not on XP?
