Question

I have imported a file “x.ani” into Resource file Resources.resx. Now trying to load that file using ResourceManager.GetObject(“aero_busy.ani”)

Cursor.Current = (Cursor)ResourcesX.GetObject("aero_busy.ani");

but it didn’t work .. (certainly) 🙂

How can I change the current Cursor using resource object?

Answer 1

I haven’t found any better way than dumping to a temp file and use the Win32 load cursor from file method. The hack goes something like this (I removed a big chunk of boilerplate code for clarity, in which a temp file is written with the data from the stream). Also, all exception handling etc. was removed.

[DllImport("User32.dll", CharSet = CharSet.Ansi, BestFitMapping = false, ThrowOnUnmappableChar = true)]
private static extern IntPtr LoadCursorFromFile(String str);

public static Cursor LoadCursorFromResource(string resourceName)
{         
     Stream cursorStream = Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName);        

     // Write a temp file here with the data in cursorStream

     Cursor result = new Cursor(LoadCursorFromFile(tempFile));
     File.Delete(tempFile);

     return result.
}

You would use this as (remember namespaces when loading embedded resources).

Cursors.Current = LoadCursorFromResource("My.Namespace.Filename");
