How to Create a Login in Visual Basic

Save

A login is required in a computer system. It is used to authenticate the identity of a user before giving him access to the program. You can create a login screen using Visual Basic 6. Visual Basic is an object-oriented programming language from Microsoft that allows a programmer to create professional-looking windows and user interfaces with less coding. With adequate knowledge in utilizing Visual Basic's capabilities, you can develop simple utilities or sophisticated desktop applications that help users perform particular tasks.

Things You'll Need

  • Computer
  • Visual Basic 6 software
  • Start the Visual Basic 6 program. By default, a new "Project" and "Form" are created as soon as the Visual Basic environment loads.

  • Design the user interface. A typical login screen has input boxes to supply the user name and password, as well as buttons to send or cancel the request for access. Click the appropriate controls from the "Toolbox" on the left, then drag and drop them into the "Form" on the right. The basic controls you will need include labels, text boxes, and command buttons. You may add a timer control if the login requires restricting the time for a user to successfully gain access into a computer program. Set each control's properties, such as appearance and functionalities, by selecting the appropriate items in the "Properties" window.

  • Double-click the individual objects on the form to add the source codes. A source code is an instruction embedded in a control to instruct the program what to do. For example, to check if the user supplied the correct user name and password, your source code will contain instructions that read a database file of authorized system users, then send feedback through a message box that informs the user whether the login information are correct or not.

  • Click "Run" button on the menu bar to test if the program is executing correctly. If compile errors are found, Visual Basic will highlight the source code section with yellow. Correct syntax and logical errors, if any.

  • Save the login program as an executable file by clicking "File > Make [Name of Your Project.exe]" on the menu, and install it into a workstation.
