You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Press CTRL + D to add the file called frmApplication.vb from the above folder into your project (or right click on the project and choose to add it as an existing item). You may need to overwrite an existing copy of this form in your project to do this.
