Checking if a var contains anything.

3 posts in this topic

So, I have a Do Until command and I want to end it as soon as a var contains anything.

For example:

$TestVar = ""

Do
MsgBox(0,"Test", "This is a test")
$TestVar = 1
Until $TestVar = ; I want this to be optional, since I am starting it as empty, I want it to be able to end whenever it contains anything (Letters or numbers)

Thanks ;)

$TestVar = ""
Do
    ConsoleWrite("This Is A Test >> " & $TestVar & @CRLF)
    $TestVar = 1
Until $TestVar <> "" ; I want this to be optional, since I am starting it as empty, I want it to be able to end whenever it contains anything (Letters or numbers)

MsgBox(0, "Test", $TestVar)

Hello Damein,

Just thought I'd share my version

Local $TestVar = ""

While $TestVar = ""
    MsgBox(0,"Test", "This is a test")
    $TestVar = 1
WEnd
