Hi We have already done it before in a chat client application where we developed the GUI in C# and core protocol for chat in C++. Then called C++ dll from C#. We need to marshal the input and output parameters. Load the C++ dll in C#. what is important here is that the C++ dll we use should also be compiled as Winmobile project else it gives native error. We also need to know the input and output parameters data structure as there are many marshalling issues in Interop for string, structures. We have C++ and .NET experts in our team who can handle this easily in two days. Kindly give this project to us. About us: We are a service company providing IT services,Software Development, Knowledge services, Educational services and Consulting services with focus on timely delivery at minimal price.

I would like to say that depending on the size and complexity of the dll, it may take longer or shorter amounts of time and more or less amounts of money. However, we can negotiate the details if you would like,

I have done similar work for building the thin wrapper of managed C++ over C/C++ component such that C/C++ functions and objects can be called from .net code. Let me know if you are using the callback functions in C++/C component that needs to be called from .net code. Thanks & Regards, Vijay Kumar
