Need to pull a random static value from somewhere to a variable

[wisem2540]

I have an app that can point to 1 of 4 servers. In an effort to pseudo load balance, everytime I launch the app, I would like a different server to appear in the server box. I assume I could control this by doing a regwrite.

I could put the 4 server names into an array I suppose, or read them from a text file. but how can I get autoit to choose one of them at random and store it to a variable?

Check function Random.

$iNumber = Random(1, 4, 1)

willl give you an interger between 1 an 4.

Just so im clear, would I then use this integer to reference a line in a theoretical array?

[water]

Correct.

Example:

Global $aServer[4] = ["Server1", "Server2", "Server3", "Server4"]
$sServerToUse = $aServer[Random(0, 3, 1)] ; 0 - 3 because the index of an array starts with 0

Water,

thanks. I added a regread to get the current value. Then a Do-Until $Currentvalue <> $sServerToUse, to prevent it from returning the same value consecutively. - then obviously a regwrite on $sServertoUse. It works well.

Thanks again.
