DLLImport and Unable to Load DLL

[Michael Tissington]

I have a C# function that calls into a C++ DLL

I have placed the DLL in the 'bin' folder of my asp.net project

I'm using something like
[DllImport("Keycode.dll", EntryPoint="GenerateKey")]

However when I try to call the function I'm getting an error 'Unable to Load
DLL'

Should I specifiy the path to the dll in the DllImport?
If so - do I specifiy a path relative to the web site or a physical path?

Anything else that could be causing this error?

Michael,

Should I specifiy the path to the dll in the DllImport?

See http://www.dotnetinterop.com/faq/?q=LoadLibrary

On the platforms where it's available, you can also call the
SetDllDirectory API.

Mattias,

Thanks for the LoadLibrary link, however this does not seem to work when
running as an ASP.NET web page.

I guess I need to get the path to the original location of the page and not
the temporary location of the assembly.
