This is a basic input and output program and it explains how you would go about it. user can input text in the text box and the output will display in the module box.

To enter the value we used text box. It allows to enter the text in the text box. There is only one option to enter text in vb.net that is text box. To display the output we used messagebox function. It displays module box which contains text in the output. In the earlier Visual basic 6.0 version we were using msgbox function to display the output in module box, But in the latest version we were using advanced messagebox function. Because it has some extra features.
