Based on a sample found on Mr. John McIlhinney's .NET Developer Blog I'm triyng to modify the sample to achieve this :

- Create Rectangle on a PictureBox via GDI+ and inside a textbox with user desired text. Also, and more important, the user must be able to drag drop/move the Box throught the image.

Thanks to Mr. for your help and advices.
