Description
Advanced Visual Basic 2010 Programming Challenge 5 Client Billing
Write an application that tracks the amount of billable time that the user spends on consulting projects. The application reads an input client file and appends information to a billing file, which it creates the first time it runs.
Startup Form
Figure 1-24 shows a sample of the main window. When the user begins working on a project, the client name is selected from a ComboBox control. In Figure 1-25, the user has clicked the Start button, so the billing timer is running. Notice that the Start button is disabled. In Figure 1-26, the user has clicked the Stop button. At that moment, the application shows the amount of elapsed time and writes a record to the billing file.
