Still can't get this to work... Once I figure out how to do this for one I can do the rest but it's not working.

It just says "GPU: MHz"

Code: Select all

[Rainmeter]
Background=..\Images\bg_ram_cpu.png
Update=1000

[Variables]
@Include=#@#\HWiNFO.inc
@Include2=..\UserVariables.inc

[MeasureGPUMHz]
Meter=Plugin
Plugin=HWiNFO.dll
HWiNFOSensorId=#HWiNFO-GPU0-SensorId#
HWiNFOSensorInstance=#HWiNFO-GPU0-SensorInstance#
HWiNFOEntryId=#HWiNFO-GPU0-CoreClock#
HWiNFOType=CurrentValue


[GPUMHz]
Meter=STRING
MeasureName=MeasureGPUMHz
X=95
Y=47
FontColor=#FontColor1#
FontSize=7
FontFace=#FontFace#
StringStyle=BOLD
StringAlign=left
Prefix="GPU: "
PostFix=" MHz"
AntiAlias=1

The first thing you are going to want to know is if the plugin measure is really working and returning a value. The "About / Skins" dialog from the Rainmeter context menu can help you there.

You might also want to check "About / Log" to see if there are any error messages.

Then, although it isn't important to the functionality, don't use Prefix and Postfix. They are prehensile tails that you almost never need.

Code: Select all

[GPUMHz]
Meter=STRING
MeasureName=MeasureGPUMHz
X=95
Y=47
FontColor=#FontColor1#
FontSize=7
FontFace=#FontFace#
StringStyle=BOLD
StringAlign=left
Text=GPU: %1 MHz
AntiAlias=1
The %1 is a placeholder for the value that is returned in MeasureName on the meter.

I see the issue.

[MeasureGPUMHz]
Meter=Plugin

a Plugin is not a "meter", but a "measure".

[MeasureGPUMHz]
Measure=Plugin

Excellent...

I really like HWiNFO. Takes a minute to wrap your head around all those values you have to set from SharedMemoryViewer.exe, but once you do, it is very powerful, lightweight and returns oodles of stuff.

I use it all the time.

Hi all
Newby here
I need to use a string as a number,
however it doesn't work, because the format of the string is such as : 1,234.5 (with a coma)
I already tried :

Code: Select all

Substitute:",":""
that works well to get rid of the coma, but the result (1234.5) oddly doesn't seems to be usable as a number, or when I use it as a number, that number is 1 (not 1234.5).
What's going wrong ?

The key is that you must use the "string" value of the measure containing the numeric value, so the Substitute is applied where the value is used. Substitute is only applied to the string value of a measure, and only at the time and place where the string value is "used".

Code: Select all

[Rainmeter]
Update=1000
DynamicWindowSize=1
AccurateText=1

[Variables]
MyNum=1,234.5

[MeasureString]
Measure=String
String=#MyNum#
Substitute=",":""

[MeasureNumber]
Measure=Calc
Formula=([MeasureString] + 765.5)
DynamicVariables=1

[MeterNumber]
Meter=String
MeasureName=MeasureNumber
FontSize=13
FontWeight=400
FontColor=255,255,255,255
SolidColor=47,47,47,255
Padding=5,5,5,5
NumOfDecimals=1
AntiAlias=1
The important bit here is that I am using the [MeasureString] section variable to get the value. That will force the Calc measure to use the string value of the measure, and it will then convert it to a number if the result is in fact numeric. Note that if I just used Formula=MeasureString + 765.5, that would attempt to use the number value of the measure, without any Substitute applied, and the value would be "1", which is where it will stop trying to convert it to a number, since a , comma is not a valid part of a numeric value. So the answer would be 766.5, which is the 1 added to the 765.5

Thx for help !

To focus more on my problem, here is an example :

First, I write this :

Code: Select all

[Rainmeter]
MiddleMouseUpAction=!Refresh
AccurateText=1

[Variables]
MyNum=1,234.5678

[MeasureString]
Measure=String
String=#MyNum#
Substitute=",":""

[Title]
Meter=STRING
FontColor=cccccc
X=36
Y=5
Text=Refresh
UpdateDivider=-1

[Index]
Meter=STRING
FontColor=cccccc
X=130
Y=32
Text=[MeasureString]
DynamicVariables=1
... and this woks as expected (1234.5678 is displayed)

Then I try this, in order to round the number :

Code: Select all

[Index]
Meter=STRING
FontColor=cccccc
X=130
Y=32
Text=[MeasureString:/1,1]
DynamicVariables=1
... and this works not as expected (1.0 is displayed, instead of 1234.5)

Have you a clue about this ?
