Hi, guys
I am trapped into a big trouble on how to use unmanaged class library
code in a C# web application.
Now, I am working on a project to develop a web interface for SPlus, a
statistical software tool. By intuitive, I plan to apply C# to develop
web side, which will invoke some unmanaged code to use functions of
SPlus. I have developed a unmanaged C++ class UM_A to use SPlus
functions, and also developed a wrapped managed C ++ class M_A for that
unmanaged class UM_A, and used managed M_A in the C# application.
First, I tried those unmanaged and managed classes in a window-based C#
application, they are really working, and then, I move them to web
application. They are failed. The failure is related to an exception of
"FileNotFoundException", suggesting that
File or assembly name M_A, or one of its dependencies was not found.
I am very puzzled. Could you guys tell me what is going on? I know that
C# web application can use Pinvoke c to reuse window DLL, and Marshaling
to visit COM. But can it reuse old class library by way of wrapped
managed class, and how to do?
I read many articles on how to utilize wrapped managed class for the
reuse of unmanaged class library, but all of them are related to windows
application.
Thanks
david
