Generating random numbers in a batch file

NanoDuke · 2nd August 2007, 11:05 PM

Greetings.

I have absolutely NO knowledge of programming - except for creating VERY simple .bat files to load programs and websites.

What I want to do, is create a little program to launch a URL with a randomly generated number in it.

eg www.mysite.com.au/images/image1.jpg
www.mysite.com.au/images/image2.jpg
www.mysite.com.au/images/image44.jpg
www.mysite.com.au/images/image65.jpg
www.mysite.com.au/images/imageXX.jpg

I'd like it to run www.mysite.com.au/images/imageXX.jpg, then wait a set amount of time, then launch again, but with a different number in XX.

I've found this link that uses the clock to pick a pseudo random number, but is it possible to have a command that randomly picks from a list of options?

Any help would be appreciated.

From the sounds of it you don't actually want a random number generator.

You could use a few variables and start with a user defined number, and each time the script repeats, it adds 1 (+1) to that number.
This wouldn't be too hard.

Google it first

http://www.google.com.au/search?hl=e...m+number&meta=

There's an example in the first result!

I'd suggest using a real programming language, though, if you want the number to be properly random.
