@Devi Singh,

I've used lr_load_dll() myself a number of times and was able to call the external functions (user32.dll, kernel32.dll). They are imported by default.

Not sure what happens when you use a .NET DLL. That one might only work in the context of .NET framework. What kind of protocol did you select? It might be that .NET protocol has special handling of .NET DLLs.

Hi, thanks for quick reply. We are using web http/html protocol, but now will try with .net protocol too. Do we have to register the dll file in VUGen before its use.

Getting the below error.

A function like GetValue, looks more to Class method. When you want to use pure C-code to access your .NET DLL you might need to setup some wrapping functions.

Class methods are normally mangled in complex naming (I know this from C++, not sure how that works out for .NET languages).

Devi Singh , I found Using a .net DLL in C article.

We did raise a support ticket and got the below response.

"LoadRunner does not support .dll files compiled with .NET"

So the dll file has to be recompile with C compiler.
