No, you don't need P/Invoke at all. It's all in your UI library, look properly.
But which one are you using? You should always tag it.

The code posted in your question works, so what's the real problem?

Not really. If the code is "working" somehow, it does not mean it is even acceptable.
I explained it all in my answer, please see.

Confused! Where did P/Invoke come into this .. did I miss a revision of the question?

Chances are you are using System.Windows.Forms.Cursor. (Again, always, always tag your UI library, like "Forms".)

But it already can be moved, because the property Position is a read/write property: http://msdn.microsoft.com/en-us/library/system.windows.forms.cursor.position.aspx[^].

Please be advised that using P/Invoke kills platform compatibility of your code. If this is a Windows Forms application, it can be executed on many platforms without recompilation, via Mono. A single P/Invoke method can break this feature at once.
