Could you check the call for "EdsCreateFileStream", especially the first parameter ? According to the docs "It creates a new file on a host computer (or opens an existing file) and creates a file stream for access to the file."

Thank to All!
I have the solution. This is not in the sdk document. Here is and here. This problem exists, if you are using Windows operation system.
The concrete solution:

    while(GetMessage(&msg, NULL, NULL, NULL))
    {        
        TranslateMessage(&msg); 
        DispatchMessage(&msg); 
    }

I will fix the code, erease the unecessary comments and it will working to everyone! (Soon.)
