run c# .dll(or .exe) to validate password

[joao_bana]

hi,
Could anyone tell me how can i use a c# dll that just validates the password inserted during installation?

i have seen another post mencioning just running an .exe to do this but i really cant understand how they send and receive the variables in the .exe

thanks

Just use Call DLL Function to call your DLL.

Some of the built-in sample projects make use of the Call DLL Function command with the Win32 API. Check them out.

As long as .NET is installed and your C# DLL can be called from regular Win32 apps, you will be set.

ok, I did like you suggested and used the Call dll function. It seams fine but unfortunately I getting the FUNCTIONNOTFOUND error.

a little research tells me that "C# DLLs cannot be exported due to the underlying nature of .NET". In fact, Installware's help says that "The function must be available under the specified function name and use the __stdcall calling convention." which c#'s functions, I think, do not.

Can you give some more help?
Thanks once again

One way around this would be to put your validation procedure in a command-line .exe file, distribute it to SUPPORTDIR, and then call it via the Run Program command.

If you cannot support the required calling convention, Call DLL Function will not work for you. Sorry!
