Function InputBox options.

Recommended Posts

Hi All,

I use an InputBox to set a variable in one of my scripts, but I have some trouble figuring out how to make it return want I need, or if it’s even possible to do it?

I need the InputBox to return a number to a variable:

$Value = InputBox("Drop Amount.", "Enter the quantity you want to drop.", "", " M2", "200", "140")

But, there are a few things I’d like to change from the default output:

1. I only want numbers to be allowed in the input field. (Not letters, blanks or special signs)

2. Only numbers between 1 and 40 should be allowed.

3. And fi I press the [Cancel] button, the return value should not be blank, but 0 (Zero).

Is any of this possible when using the InputBox function? Or is there another function I can use for this?

The Function Reference in the AutoIt Help file doesn’t seem to clarify this.

And just for curiosity, what does the hwnd parameter do?

Welcome to the AutoIt forums. :)

You cannot modify the InputBox function directly to do what you want - but you can run the returned value through a number of checks to determine if it meets your requirements:

#include <MsgBoxConstants.au3>

Global $iFinal

While 1

    $sRet = InputBox("Drop Amount.", "Enter the quantity you want to drop.", "", " M2", "200", "140")
    ; Check if Cancel pressed
    If @error Then
        $iFinal = 0
    ; Convert input into integer
    $iRet = Int($sRet)
    Switch $iRet
        Case 1 To 40
            $iFinal = $iRet

MsgBox($MB_SYSTEMMODAL, "Return", $iFinal)
If you want to limit the input to digits only, you will need to use a custom dialog with an input using the $ES_NUMBER style. This thread gives you a good steer - do come back if you need more advice. :)

Thank you Melba23,

Yeah, I had a feeling that it wasn't possible to configure the InputBox function to do that, and I needed to do some return value checks instead. I just had to ask, since it would have been a lot easier.. :)

I'll try to look at your code and link.

Thanks again for a fast and accurate answer.
