Not sure if I'm approaching this correctly but this is what I've got and what I'm trying to do
I have a table with 10 Labels in it (Labels Id A1 thru A10)
I'm trying to have each label assigned a random number using 0-9
Need to have each labels number value different from the other
Code Below:
Randomize()
A1.Text = Int(Rnd() * 10)
A2.Text = Int(Rnd() * 10)
A3.Text = Int(Rnd() * 10)
A4.Text = Int(Rnd() * 10)
A5.Text = Int(Rnd() * 10)
A6.Text = Int(Rnd() * 10)
A7.Text = Int(Rnd() * 10)
A8.Text = Int(Rnd() * 10)
A9.Text = Int(Rnd() * 10)
A10.Text = Int(Rnd() * 10)
I have a form and I want each form to have a unique number when it is filled out so it will go into the database. How can I set this up so when the page loads in the label it will say 1 then the second time it loads it will say 2?
