Help! Infinite loop!

[kazooie21]

The following code gives me an infinite loop. How should I change this so it won't be infinite?

Dim curSales as Currency
curSales = Val(Inputbox("Enter a sales amount")
Do While curSales > 0
Print curSales * .1
Loop

Oops.......

Dim curSales As Currency
Dim y As Integer
curSales = Val(InputBox("enter a number:"))

For y = 1 To curSales
Print curSales * 0.1
Next y

I don't think I'd use 'dim y as integer' since it appears that 'currency' could be a decimal number.
As well, that solution will 'for each value from 1 to cursales' - so if I enter 100 as cursales, I'll get 100 print lines.....
It depends on what your trying to achieve.
If you want to query the user until they enter '0' try this:
Dim curSales as Currency
cursales=1
Do While curSales > 0
curSales = Val(Inputbox("Enter a sales amount")
if cursales > 0 then
Print curSales * .1
else
exit do
end if
Loop
(it's a bit wordy, but it's early in the morning...)
However, if you only want to ask them once, perhaps by way of a command button or some other call to the procedure, try this:
Dim curSales as Currency
curSales = Val(Inputbox("Enter a sales amount")
if curSales > 0 then
Print curSales * .1
end if

One more thing:
You really should do your own homework. If you can't figure something out, don't post requests - go to class and learn the solutions from the teacher or the clues the teacher gives. Then come back here and see if there are additional solutions.
I've been a teacher for over 12 years and there's nothing worse than a student who doesn't do his own work and can't say "I don't know"!

Print does not change any variable. curSales isn't affected by it, so if you entered the loop, you can't escape.

Replace this:
Print curSales * .1

With this:
curSales = curSales * .1
Print curSales

Mathematically it is still an infinite loop, but VB can't handle decimal fractions this long, so sooner or later, curSales will become zero and the loop will end.
