I've got some code to access an unmanaged dll, and it works fine in a
windows based app, but when I move the code to a web application it
does not work.  It does not throw an error, it acts like the code never
gets called.

   private class dllWrap
   {
       [DllImport("C:\\ProcessCommand.dll")]
       public static extern void ProcessCommand(IntPtr str);
   }
   private void SendCmd(string command)
   {
       IntPtr str = Marshal.StringToHGlobalAnsi(command);
       dllWrap.ProcessCommand(str);
   }
   protected void Button1_Click(object sender, EventArgs e)
   {
       this.SendCmd("WORKED");
   }
