For the first, use Process.Start.

For the second, in the Compact Framework you'd need:

using (TextWriter writer = new TextWriter("test.txt"))
{
    writer.Write("TEST");
}

I believe Process.Start should be okay in Windows Mobile though...

If you can upgrade to a later version of the Compact Framework, you could use File.WriteAllText.
