.NET Exercise 1 - Introduction to Winforms With C#
1.1 Overview 1.2 Goals: Understand solutions and projects in Visual Studio. Understand and be able to use Windows Forms to create simple window based applications in .NET using C# Implement event handlers for built in controls.
1.3 Requirements Must have Visual Studio.NET and the .NET framework installed on the machine. Does not require web components to be installed nor the IIS server.
1.4 Prerequisites Working knowledge of C++/Java or C#
1.5 Examination You should be able to explain all parts of your produced software. The application should be zipped and sent to the lab-teacher together with your ID (YYYYMMDDXXXX) and name. You are allowed to be maximum two persons in each group for the .NET exercises. Both must know and be able to answer questions on all parts of the produced software.

1.6 Exercise 1.6.1 Functional Description The application you should produce should have a simple user interface depicted below. When the user clicks the different buttons, the label text (to the right) should change into what you see in the picture below. Note that it should be possible to cut and paste the text from the labels.
Figure 1.1 Application before and after clicking the three buttons and finally, resize.
The functionality of the three buttons will be extended during the remaining exercises. Notice that the controls containing the text should be resized together with the application form.
