If IsNumber($Num) Then

[totoymola]

Hi. This is my first post

I'm having a problem with my script. I want to make an inputbox that will check if the input is a number. I spent several hours to make this work, and I finally figured out a solution. However, it is NOT perfect.. This is my current working script so far.

#CS#=#=#=#=#=#=#=#=#=#=#=#=#=#=#

    PURPOSE : NUMBER CHECKER

#CE#=#=#=#=#=#=#=#=#=#=#=#=#=#=#


While 1

$Num = InputBox("Number Checker", "Please enter a VALID number greater than or equal to zero.", "0")

If @error = 0 Then

    If $Num >= 1 Or $Num = "0" Then
        MsgBox(0, "Result", "VALID")
    Else
        MsgBox(0, "Result", "NOT VALID")
    EndIf

Else
    Exit
    
EndIf

WEnd

Before this, I tried using If $Num >= 0 Then instead of If $Num >= 1 Or $Num = "0" Then, but it didn't work. It always return "VALID".

Then I thought of using the IsNumber function, and it didn't work too. It always returns "NOT VALID" Here is the code with the IsNumber:

#CS#=#=#=#=#=#=#=#=#=#=#=#=#=#=#

    PURPOSE : NUMBER CHECKER

#CE#=#=#=#=#=#=#=#=#=#=#=#=#=#=#


While 1

$Num = InputBox("Number Checker", "Please enter a VALID number greater than or equal to zero.", "0")

If @error = 0 Then

    If IsNumber($Num) Then
        MsgBox(0, "Result", "VALID")
    Else
        MsgBox(0, "Result", "NOT VALID")
    EndIf

Else
    Exit
    
EndIf

WEnd

Please tell me what is wrong with this.

Thanks!

$Num = InputBox("Number Checker", "Please enter a VALID number greater than or equal to zero.","0")
If $Num >= 0 Then
MsgBox(0, "Result", "VALID")
Else
MsgBox(0, "Result", "NOT VALID")
EndIf

works for me

[totoymola]

$Num = InputBox("Number Checker", "Please enter a VALID number greater than or equal to zero.","0")
If $Num >= 0 Then
MsgBox(0, "Result", "VALID")
Else
MsgBox(0, "Result", "NOT VALID")
EndIf

works for me

Thanks!

Actually, I tried that before. It is not 100% working for me, because if I enter other characters (not numbers), it will still return "VALID"

This is what I have in mind, but it doesn't work!

$Num = InputBox("Number Checker", "Please enter a VALID number greater than or equal to zero.","0")
If IsNumber($Num) And $Num >= 0 Then
MsgBox(0, "Result", "VALID")
Else
MsgBox(0, "Result", "NOT VALID")
EndIf

Could you please tell me how to implement the IsNumber? Because that code above always return "NOT VALID".

Thanks again!

what you need is StringIsInt().

$Num = InputBox("Number Checker", "Please enter a VALID number greater than or equal to zero.","0")
If StringIsInt($Num) And $Num >= 0 Then
   MsgBox(0, "Result", "VALID")
Else
   MsgBox(0, "Result", "NOT VALID")
EndIf

Wow!! That solved my problem! Thanks a lot Kurt and B3TA_SCR1PT3R!

I'm a total n00b that's why I don't know how to use that function (yet).

By the way, if it's not too much to ask, can you give me examples of using the IsNumber function? The help file doesn't give much info about it.

Thanks!

From help file: IsNumber() checks if a variable's base type is numeric. As InputBox() allways returns a string, your if clause failed (IsNumber($Num) is allways 0 then!).

Brilliant! I didn't even know that inputboxes always return strings. Now I know.

Thanks once again.

Thanks fro all your help.

This is my final working code (I hope).

$Num = InputBox("Number Checker", "Please enter a VALID number greater than or equal to zero.", "0")
If (StringIsInt($Num) Or StringIsFloat($Num)) And $Num >= 0 Then
    MsgBox(0, "Result", "VALID")
Else
    MsgBox(0, "Result", "NOT VALID")
EndIf

I added the StringIsFloat() so it will accept numbers with decimals as well. Everything is working fine so far, but I'm curious to know the other methods of doing this too.
