Presenting the user who logged in

Hi Kees,
At it's most basic (ie without any sort of userid validation), just store the keyed in userid (and anything else) in global variables and then it can be used anywhere within the application.
In the attached example, I store the userid (plus the date and time) and display them together in the form caption and also separately on the form itself;  it's up to you how / where you want to place them.
Hope this helps,
Derek.
