flow chart diagram using VB?

P: 17
Hi... I need to do a flow chart diagram using VB. As usual, I'm doing my car park system.

So this is how it should look like:

Upon arrival...

1) The user will see these messages - "Welcome to Paperless Car Park!"
2) "Before entering, please SMS your vehicle number to ..." (The ... is the SIM card in the GSM modem)
3) "Thank you. Your car plate number is ..." (The ... is the car plate number)
4) "Your IN time is __:__hrs"
5) "Please proceed to parking lot."

Upon exit...

7) "Before exit, please SMS your vehicle number to ..." (Once again, the ... is the SIM card in the GSM modem)
8) "Thank you. Your car plate number is ..." ( ... refers to the car plate number)
9) "Your OUT time is __:__hrs"
10) "Total fee is $_.__" (the system will help to calculate the duration the car parks in the car park and tabulate the cost)
11) "Have a nice day!"

We assume the gate closes after 15 seconds after opening. How should I write the codes? So far, I've only managed to write MsgBox() with the messages in the (). But how do I connect with the GSM modem?

Thank you!
