John,
here is an example how to create random numbers in VB. In the example below
it will generate values between 1 and 6. The statement "Randomize" is
initializing the Random Generator. The function "Rnd" is then used to get
the random numbers.
Dim IntVal as Integer
Randomize 'Initializes the random generator using the
timer
IntVal = Int((6 * Rnd) + 1) ' Generate random value between 1 and 6.
To produce random integers in a given range, use this formula:
Int((upperbound - lowerbound + 1) * Rnd + lowerbound). So in your example it
has to look like:
IntVal = Int((25 - 5 + 1) * Rnd + 5)
I hope that helps.
