speed up the program

[tonyip]

Do you have any idea to reduce the time on generate a large ammount(e.g > 10000) of random number into array?

My code is :
dim temp as long
dim arr() as long
dim maxvalue as long

redim arr(1 to x)
For temp=1 to x
arr(temp) = int(rnd*maxvalue)+1
next temp
.
.
.
is it possible to speed up the program??

Assuming that you need a random number and are storing in an array for future referencing:

You could make a private function that generates the number, then the first time you need that number save it to the array for future use.

This will appearingly cut your time making the processing as close to parallel as possible.

Example:

Loop
'Process
'I need a random number
Get_Rand
'save number to array
'continue processing
end loop

Function Get_Rand()
'Generate random nummber
End

Oneway is to reduce the amount of variables in your loop. Instead of x use 100000 and maxvalue use a number.

If you want a random number less than 36000 then define ARR as an integer.

It is faster for VB to store integers than long numbers
