Copy file from TrueCrypt volume to clipboard?

Question

I use this code to copy files to the clipboard:

IDataObject data = new DataObject(); data.SetData(DataFormats.FileDrop, new string[] {@"X:\test.doc"}); MemoryStream memo = new MemoryStream(4); byte[] bytes = new byte[] { (byte)(5), 0, 0, 0 }; memo.Write(bytes, 0, bytes.Length); data.SetData("Preferred DropEffect", memo); Clipboard.SetDataObject(data); 

Unfortunately, this does not work if the drive is TrueCrypt tone. How can this be done on a TrueCrypt volume?

Unfortunately, I do not think that you can leave without a proper list of Shell identifiers; in my Windows 7 your code does not even work with a regular file system. The correct code should primarily provide CIDL:

  var data = new DataObject(); var files = new StringCollection() { @"T:\Test.doc" }; data.SetFileDropList(files); data.SetData("Preferred DropEffect", true, new MemoryStream(new byte[] { 5, 0, 0, 0 })); data.SetData("Shell IDList Array", true, CreateShellIDList(files)); Clipboard.SetDataObject(data, true); 

Where CreateShellIDList creates a binary representation of the CIDA structure (CFSTR_SHELLIDLIST). The implementation is below:

 [DllImport("shell32.dll", CharSet = CharSet.Auto)] public static extern IntPtr ILCreateFromPath(string path); [DllImport("shell32.dll", CharSet = CharSet.None)] public static extern void ILFree(IntPtr pidl); [DllImport("shell32.dll", CharSet = CharSet.None)] public static extern int ILGetSize(IntPtr pidl); private static MemoryStream CreateShellIDList(StringCollection filenames) { // first convert all files into pidls list int pos = 0; byte[][] pidls = new byte[filenames.Count][]; foreach (var filename in filenames) { // Get pidl based on name IntPtr pidl = ILCreateFromPath(filename); int pidlSize = ILGetSize(pidl); // Copy over to our managed array pidls[pos] = new byte[pidlSize]; Marshal.Copy(pidl, pidls[pos++], 0, pidlSize); ILFree(pidl); } // Determine where in CIDA we will start pumping PIDLs int pidlOffset = 4 * (filenames.Count + 2); // Start the CIDA stream stream var memStream = new MemoryStream(); var sw = new BinaryWriter(memStream); // Initialize CIDA witha count of files sw.Write(filenames.Count); // Calcualte and write relative offsets of every pidl starting with root sw.Write(pidlOffset); pidlOffset += 4; // root is 4 bytes foreach(var pidl in pidls) { sw.Write(pidlOffset); pidlOffset += pidl.Length; } // Write the root pidl (0) followed by all pidls sw.Write(0); foreach(var pidl in pidls) sw.Write(pidl); // stream now contains the CIDA return memStream; } 

I can’t get a loan here, I found this CIDA code a while ago and just ported it to C #. I can’t remember the original source, but it still works well (I just tested it on TrueCrypt as well)
