Dynamic text color

[Lauda]

Hi all,
I'm pretty much new to the rainmeter and I've been working on a custom meter that checks servers status (Online/Offline)
I've managed to parse an XML file and get the proper values and now I'm wondering if there is a way to change the text color, for example: If it's online it will display it in green color and if it's offline it will display it in red color.

I've tried to do some stuff with IfAboveValue checks but I doubt that can compare strings?

Thanks!

There is no way to directly compare strings (without resorting to a Lua script), but you can use the Substitute statement to change strings into numbers, and then the IfxxxxValue statements can do comparisons on numbers.

Here is one approach:

Code: Select all

[Rainmeter]
Update=1000
DynamicWindowSize=1

[MeasureCheckServer]
Measure=Plugin
Plugin=WebParser.dll
URL=http://rainmeter.net/WebParserTest.html
RegExp="(?siU)<Status>(.*)</Status>"
StringIndex=1
Substitute="Online":"1","Offline":"0","":"0"

[MeasureStatus]
Measure=Calc
Formula=[MeasureCheckServer]
IfEqualValue=1
IfEqualAction=!SetOption MeterOne FontColor 0,255,0,255
IfBelowValue=1
IfBelowAction=!SetOption MeterOne FontColor 255,0,0,255]
DynamicVariables=1

[MeterOne]
Meter=String
FontSize=12
StringStyle=Bold
Antialias=1
Text=Server Status

Based on your explanation, I am checking for "Online" or "Offline" and also throwing in "" (null) in case you can't get to the xml file at all.

Thanks a lot!
It works now!

Glad to help.

If you have to substitute, why not substitute the color values in and then just use dynamic variables?

Code: Select all

[Rainmeter]
Update=1000
DynamicWindowSize=1

[MeasureCheckServer]
Measure=Plugin
Plugin=WebParser.dll
URL=http://rainmeter.net/WebParserTest.html
RegExp="(?siU)<Status>(.*)</Status>"
StringIndex=1
Substitute="Online":"0,255,0,255","Offline":"255,0,0,255","":"255,0,0,255"

[MeterOne]
Meter=String
FontSize=12
StringStyle=Bold
Antialias=1
Text=Server Status
FontColor=[MeasureCheckServer]
DynamicVariables=1

An decent (and simpler) variant on the idea, however I went with the Calc for a reason. It opens up the opportunity to do many things based on the answer, not just one. You could set the FontColor, change the Text, hide or unhide meter(s), any number of things that could be caused by the single fact that the server is "Offline".
