Function to match to 0-100 other minimum and maximum

[rony2006]

Hi,

 

I dont remember what is the name of an AutoIT function that allows you to set a value to another value.

For example I have 2 variables:

a = 4 and b = 14

this function allows me to say that 4 = 0 and 14 = 100

 

then if i would use the function value of 50, my return value is the middle between 4 and 14.

 

Sorry if i didnt explained it correctly.

4 = 4.

14 = 14.

If you want to set variable by it's value, you should hold an array of those variables.

rony2006,

i think you want something like this:

$iA = 4

$iB = 14

$iPercentage = 50

$iRet = _Rony($iA, $iB, $iPercentage)

ConsoleWrite($iRet & @CRLF)

Func _Rony($iMin, $iMax, $iPer)

    ; Get the difference between the maximum and minimum values
    $iDiff = $iMax - $iMin
    ; Calculate the required percentage of that difference
    $iValue = Round($iDiff * $iPer / 100)
    ; And add it to the minimum value
    Return $iMin + $iValue

EndFunc

Am I right?

Sorry i think i didnt explained correctly. 

Let me give another example: 

I have a slider, minimum value return by slider is 0 and maximum value returned by slider is 100.

I have a car that have a speed between 20 km/h (minimum) and 120 km/h maximum. 

In my function I will input 20 as min and 120 as max (considering that 0 and 100 are always standard).

Now I will move my slider at a value of 64 (as I said, slider can go from 0 to 100), and I want to have the speed of my car. How I can calculate this?

rony2006,

That sounds as if my function is exactly what you want. Please ask if you have any questions.

$iMin = 20

$hGUI = GUICreate('', 200, 200)

GUICtrlSetLimit($iSlider, $iMax, $iMin)

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE

        Case $iSlider
            $iSpeed = GUICtrlRead($iSlider)
            ConsoleWrite('Speed: ' & $iSpeed & @CRLF)
    EndSwitch
WEnd

Or using Melba23's function:

expandcollapse popup

#include <GUIConstantsEx.au3>

$iMin = 20
$iMax = 120

$hGUI = GUICreate('', 200, 200)

$iSlider = GUICtrlCreateSlider(10, 20, 180, 20)

GUICtrlCreateLabel('Slider Pos:', 20, 60, 80, 20)
GUICtrlCreateLabel('Speed:', 20, 80, 80, 20)
$iSliderPos_Lbl = GUICtrlCreateLabel('', 100, 60, 40, 20)
$iSpeed_Lbl = GUICtrlCreateLabel('', 100, 80, 40, 20)

GUISetState(@SW_SHOW, $hGUI)

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $iSlider
            $iPos = GUICtrlRead($iSlider)
            $iSpeed = _MinMax($iMin, $iMax, $iPos)
            
            GUICtrlSetData($iSliderPos_Lbl, $iPos)
            GUICtrlSetData($iSpeed_Lbl, $iSpeed)
    EndSwitch
WEnd

Func _MinMax($iMin, $iMax, $iPer)
    ; Get the difference between the maximum and minimum values
    Local $iDiff = $iMax - $iMin
    ; Calculate the required percentage of that difference
    Local $iValue = Round($iDiff * $iPer / 100)
    ; And add it to the minimum value
    Return $iMin + $iValue
EndFunc
