Close Delay

I have a form that opens after a bunch of code confirming a successful collection.

I want the Form to close after 5 seconds, but cant figure out how to write the code.
1. I tried to use a Wait function but then the form does not open up completly.
2. I then tried a small FOR NEXT loop and set it to 1 To 90000 but it goes way to fast and wont even show the form.

Does anyone know how I can show the form and stall it for a couple seconds then have it close automatically?

Thanks in Advance

why not simple Timer??
