I need an application to test a case study and am in dire need of help, seeing as my knowledge of computer programming is lacking in sustenance. Help would be very much appreciated! I need a program that generates a random string that is 10 letters long and then opens it as a url in a web browser. This process should be repeated at random intervals of time.
Thanks for all your help experts!

for the random string you would need something like

randomize timer

public function retStr(chrLen as long) as string
dim lngLc as long

retStr = ""

for lngLc = 1 to 10
    retstr = retstr & chr(cint(round(rnd() * 25 + 1)) + 65)
next lnglc

end function

for the random timer interval what I would do is have a timer on your form set to check every 1 second
I would have a global variable which was of a date - initilised to the current time on form load.

then when the timer event is triggered i would check if now() > timeVariable

when you have finished opening the url i would set timeVariable = dateadd("s", round(rnd()*500), now()) which would add a random number of seconds to the current time (between 0 and 500)

Finally for the opening of the url in a browser - you can use the internetExplorer object

like

    Set objIE = New InternetExplorer
    objIE.Visible = True
    objIE.navigate "http://www.yourpage.com"
    While objIE.readyState <> READYSTATE_COMPLETE
        DoEvents
    Wend
    Dim objHTML As HTMLDocument
    Set objHTML = objIE.document
    While objHTML.readyState <> "complete"
        DoEvents
    Wend

there is plenty of stuff if you google the InternetExplorer object
