Submission

Submit one Zip file.

Zip file:

Using a zip program such as WinZip, you should make a single zip file that contains all

the sub-folders and files for your VB project that you have created for your programming

assignment.

For example, when you create a project named "WindowsApplication1", then, Visual

Basic 2012 Express creates a folder named "WindowsApplication1". The files for your

form and code will be placed in this folder. You should zip this folder. When you zip this

folder, you must let the zip program include all the sub-folders.

Once your project folder has been zipped into a single zip file, you should rename this

zip file by using the prefix "Assignment", the assignment number, an underscore and

your ISU Net ID (Not ISU Card ID). For example, the zip file for assignment #1 for a

student of which ISU ID is isu123 would be Assignment1_isu123.zip.
