Access mobile device in Windows

I would like to get some sample code to do this: When? you connect a mobile device (cell phone, digital camera, mp3 player etc) to Windows, it shows up in Windows Explorer under "My Computer". You can copy? files from/to it in Windows Explorer, but it doesn't have a drive letter, so you cannot write data directly to it in an app. There has to be some API, which I need, to access the files on those devices. So, I need some sample code to: 1. It is a dialog, with tabbed pages. 2. Page 1, "Upload File". It has a edit field for entering a local file name (and a button to browse the file name), and another edit field to enter a file name on the device. A "Upload" button, which copy the local file to the device. 3. Page 2, "Download File". It is the reverse of "Upload". It copies a file from the device to the local HD. Please make it support as many different device as possible. Please document it, let me know which type of device it supports (cell phone? camera? mp3 player?). Must be written in VC6 and MFC.
