Copy Files with Windows Mobile Device/Windows 7

Question

I have written a very simple Inventory Tracking application for a Motorola MC3190 Mobile Device. I need to transfer data to and from the device and a Windows 7 PC.

I have scoured the internet for options on how to do this but so far nothing has worked. I am very new to developing Mobile applications and have limited knowledge of C#. (Just enough to develop a simple data capture app).

I have downloaded and installed the Windows Mobile Device Center, Windows Mobile 6 SDK and OpenNETCF Smart Device Framework to get access to RAPI. I know the Remote Device is connected properly through the Windows Mobile Device Center and VS2008 is able to deploy my solution to the device. I can also copy files back and forth manually via the Windows Mobile Device Center.

What I have tried so far is:

Add a OpenNetCF.Desktop.Communications Refernce

Used Code as follows:

        using (RAPI rapi = new RAPI())  <--- Error Occurs (Cannot Find PInvoke.dll in RAPI.dll)
        {

            rapi.Connect(true);

            rapi.CopyFileToDevice(remote_file, local_file);

            rapi.Disconnect();

        }

I get the error (Cannot Find PInvoke.dll in RAPI.dll) when creating a new RAPI Instance because it appears to be trying to use ActiveSync. I cannot load ActiveSync because I am running Windows 7.

I have tried adding the following code:

    [DllImport("rapi.dll")]
    static extern int CeRapiInit();

and then calling

        var rapi = CeRapiInit() == ERROR_SUCCESS;  <-- Return Value is -2147024770

        if (!rapi)
            return;

        try
        {
          .. Somestuff
        }
        finally
        {
            CeRapiUninit();
        }

It appears that RAPI cannot find the remote device. I have looked at some options for pget and pput functions but they also crap out on the CeRapiInit call. Perhaps I may not be able to use RAPI at all

Any help would be appreciated.

If you are using Windows Mobile 6.5, I suggest you to use RAPI2, and the wrapper provided on codeplex here: https://rapi2.codeplex.com/

I used it in the past and it's perfect. Here you should have a look to the following methods:

CopyFileFromDevice
CopyFileToDevice

They can be used quickly like shown in the documentation:

using (RemoteDeviceManager r = new RemoteDeviceManager())
{
   using (RemoteDevice dev = r.Devices.FirstConnectedDevice)
   {
      if (dev == null)
         return;

      // Device information
      Console.WriteLine(dev.Name + ":" + dev.Platform);
      Console.WriteLine("Remaining power: {0}%", dev.PowerStatus.BatteryLifePercent);

      // Manipulate local and device files & directories
      string myDocs = dev.GetFolderPath(SpecialFolder.MyDocuments);
      string deviceFile = myDocs + @"\Test.txt";
      string localFile = System.IO.Path.GetTempFileName();
      System.IO.File.WriteAllText(localFile, "Testing. 1. 2. 3.");

      RemoteFile.CopyFileToDevice(dev, localFile, deviceFile, true);
      RemoteFile.CopyFileFromDevice(dev, myDocs + @"\Test.txt", localFile, true);
   }
}
