OK, thanks for reply, there was only an exemple. You are right, but if you proove the code with the correct order ( as you very well are saying ), you will see that doesn't work well ( The object 'obj' doesn't keep the data..). I have read in Microsoft support that there is a debug in this cases that imposibility the correct retriving some kind of Data from Clipboard, as Metafiles ( I hope that the next version of .NET will correct this cuestion.) Thank you very much Arlen :)

public const uint CF_METAFILEPICT = 3; public const uint CF_ENHMETAFILE = 14; [DllImport("user32.dll", CharSet=CharSet.Auto, ExactSpelling=true)] public static extern bool OpenClipboard(IntPtr hWndNewOwner); [DllImport("user32.dll", CharSet=CharSet.Auto, ExactSpelling=true)] public static extern bool CloseClipboard(); [DllImport("user32.dll", CharSet=CharSet.Auto, ExactSpelling=true)] public static extern IntPtr GetClipboardData(uint format); [DllImport("user32.dll", CharSet=CharSet.Auto, ExactSpelling=true)] public static extern bool IsClipboardFormatAvailable(uint format); br mode="hold" /> // Returns True if (Win32.OpenClipboard(new IntPtr(0))) { // Returns True if (Win32.IsClipboardFormatAvailable(Win32.CF_ENHMETAFILE)) { // Returns 0 IntPtr ptr = Win32.GetClipboardData(Win32.CF_ENHMETAFILE); if (!ptr.Equals(new IntPtr(0))) { // Never get here! :-( Metafile metafile = new Metafile(ptr,true); } } Win32.CloseClipboard(); } br mode="hold" /> You can pass this.Handle instead of new IntPtr(0)

Thank you Tom. It's OK ::-D
