Export error

[vwalla]

I am a newbie at C++ & I have been getting an error.

Here's the scenario:

Downloaded Visual C++ Express 2005 Beta1
Downloaded the platform SDK & .Net 2.0 Beta

Trying to use the sample C++ script with installshield Express x to validate a serial. I am not changing anything about the validation sequence yet, just want to see how it works.

I have to compile it as a win32 DLL (contacted MS on how to do this in Expess 2005 Beta 1)

I keep getting the following error:

"Cannot find entry point of function 'ValidateSN', make sure it is exported" after I type in the default serial number in IS Express X

I think that I'm compiling incorrectly or something.

I can email or post the files if needed.

Thanks,

Vwalla
