Test for empty String - possible? [solved]

[Mor3bane]

Hi I have looked up a couple options from previous posts, but none of them seem to be working.

I am trying to test like this :

Code: Select all

[MeasureDiskF]
Measure=FreeDiskSpace
IgnoreRemoveable=0
Drive=F:
Label=1
IfMatch=" "
IfMatchAction=[!SetOption DriveTextF Text "CD#CRLF#Drive"]
IfNotMatchAction=[!SetOption DriveTextF Text "Value" "%1"]
DynamicVariables=1

Is this a possibility for the FreeDiskSpace type Measures?

Thanks,

Try this: IfMatch=^$.

wow. Thanks balala. I recognise the symbols: ^ is the start of a string, and $ is the end. So with nothing between them, the test for empty string is crystal clear.

With I'd thought of that.

Exactly. That's right.
