Logs Bootups and Log-Ons on your computer.
Language(s):Visual Basic 6.0
Category(s):Internet Explorer

This is about as simple as a VB Program gets. Compile this project, and place a shortcut to the executable in the Windows Startup Folder. For each log on to Windows, an entry is written to a text file, containing date, time and user. A record is written even if the user ESCapes out. Not a security measure, just a tattle-tale.

' 1) Start VB and Create a new project. Form1 will be created by default.
' 2) No controls need to be added.  The log file name and path can be specified
'    by changing the Constant "myPath" in the Form Load Sub.
' 3) Paste the following code into the declarations section of Form1:

'      --- Begin code for Form1
'GSSLogOn: Creates a logfile of all bootups and logons to the device. A text file
'          called GSSLogOn.log will be created in the path that the application is
'          running it.
'          If you're the only user of your computer, it's still  a useful tool.
'          You can review the log to remind you of how often you have to reboot Windows*.
'             * Windows is a trademark of the Microsoft Corporation.
