Hello,

My first instinct is that your project cannot find the DLL. According to this page on MSDN: Search Path Used by Windows to Locate a DLL

Windows will look in the following locations for your DLL:

1. The directory where the executable module for the current process is located.
2. The current directory.
3. The Windows system directory. The GetSystemDirectory function retrieves the path of this directory.
4. The Windows directory. The GetWindowsDirectory function retrieves the path of this directory.
5. The directories listed in the PATH environment variable.

If your DLL is not in one of these locations, you have two options:

1. Move the DLL to one of the locations listed above
2. Use: #import "<filepath>\mydevice.dll" For example: #import "C:\Testing\Myproject.dll"

Hope that helps,
