Stopping a Label from going below 0 (Goes with my latest post)

[gottygolly]

Hello, Melba23 if you're reading this you might be able to answer this a little better than someone else because this is your code.

Heres the code.

#include <GUIConstantsEx.au3>

$hGUI = GUICreate("Test", 500, 500)

$cLabel = GUICtrlCreateLabel("100", 10, 10, 400, 40)
GUICtrlSetFont($cLabel, 24)

$cButton_Add5 = GUICtrlCreateButton("Add 5", 10, 100, 80, 30)
$cButton_Min10 = GUICtrlCreateButton("Minus 10", 110, 100, 80, 30)

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cButton_Add5
            GUICtrlSetData($cLabel, Number(GUICtrlRead($cLabel)) + 5)
        Case $cButton_Min10
            GUICtrlSetData($cLabel, Number(GUICtrlRead($cLabel)) - 10)
    EndSwitch
WEnd

Now when you hit 0 you can keep going below 0, such as -10, -20, -30, -40, -50.

Is there a way to prevent this?

In my code I managed to make it popup a msgbox when you hit 0 or below and it exits the scripts but you can keep going below 0 if you don't click the button to set off the msgbox function.

Any help would be amazing (It's probably something stupid)

Why not just add an If statement to keep it above 0?

#include <GUIConstantsEx.au3>

$hGUI = GUICreate("Test", 500, 500)

$cLabel = GUICtrlCreateLabel("100", 10, 10, 400, 40)
GUICtrlSetFont($cLabel, 24)

$cButton_Add5 = GUICtrlCreateButton("Add 5", 10, 100, 80, 30)
$cButton_Min10 = GUICtrlCreateButton("Minus 10", 110, 100, 80, 30)

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cButton_Add5
            GUICtrlSetData($cLabel, Number(GUICtrlRead($cLabel)) + 5)
        Case $cButton_Min10
            If GUICtrlRead($cLabel) > 10 Then
                GUICtrlSetData($cLabel, Number(GUICtrlRead($cLabel)) - 10)
            Else
                GUICtrlSetData($cLabel, Number(0))
            EndIf
    EndSwitch
WEnd

Thought it was something dumb

Thanks.

Sorry for posting here again I figured it's better just to repost on here instead of making a whole new one.

with this code

expandcollapse popup

#include <GUIConstantsEx.au3>

 

$hGUI = GUICreate("Test", 500, 500)

 $amount = "100"

$cLabel = GUICtrlCreateLabel("%" & $amount, 10, 10, 400, 40)

GUICtrlSetFont($cLabel, 24)

 

$cButton_Add5 = GUICtrlCreateButton("Add 5", 10, 100, 80, 30)

$cButton_Min10 = GUICtrlCreateButton("Minus 10", 110, 100, 80, 30)

 

GUISetState()

 

While 1

    Switch GUIGetMsg()

        Case $GUI_EVENT_CLOSE

            Exit

        Case $cButton_Add5

            GUICtrlSetData($cLabel, Number(GUICtrlRead($cLabel)) + 5)

        Case $cButton_Min10

            If GUICtrlRead($cLabel) > 10 Then

                GUICtrlSetData($cLabel, Number(GUICtrlRead($cLabel)) - 10)

            Else

                GUICtrlSetData($cLabel, Number(0))

            EndIf

    EndSwitch

WEnd

If I were to change the "100" in the label to ("%" & $amount) why doe it change it back to "0" without the "%"?

I don't care about how it changes back to 0, I just want to be able to change the variable $amount without deleting the "%" in front of it.

Any ideas?

Because GUICtrlSetData on a label erases the previous contents with what you're writing to the label. If you want it formatted the same, you have to write it in exactly the same format every time you update the label.
