I have been going through the Plugin creation tutorial (http://www.team-mediaportal.com/manual/MediaPortal1_Development/PluginDevelopersGuide). I am using VS2005 SP1 on a Vista (x86) machine, running MPv1

All was going well until i got to this bit of code.
[CODE]
private void OnButtonOne()
{
  GUIDialogOK dlg = (GUIDialogOK)GUIWindowManager.GetWindow(
    (int)GUIWindow.Window.WINDOW_DIALOG_OK);
  dlg.SetHeading("Button has been pressed");
  dlg.SetLine(1, "You pressed button 1");
  dlg.SetLine(2, String.Empty);
  dlg.SetLine(3, String.Empty);
  dlg.DoModal(GUIWindowManager.ActiveWindow);
}
[/CODE]

I get the compile error
"The type or namespace name 'GUIDialogOK' could not be found (are you missing a using directive or an assembly reference?)"

I am using the following as per the guide.

[CODE]
using System;
using System.Windows.Forms;
using MediaPortal.GUI.Library;
[/CODE]

Now, i can only assume that proceedures in Core.Dll have changed since this guide was last updated, but i may be wrong.

I have looked around and it maybe that they have moved these controls into a different dll (Dialogs.dll), but this file is not included within the precompiled release and i am having create problems compiling the differing dlls from the source code.

Any ideas??

Thanks
