Alternative ways to detect spaces in Inputs, combos, etc.

[billthecreator]

I have a search bar that doesn't proceed unless it has text.

If $SearchRead<> "" Or StringRegExp($SearchRead, '[:blank:]') = 0 Then

I've tried StringInString, and that doesn't work either.

Am I missing something?

Thanks

If $SearchRead And Not StringIsSpace($SearchRead) Then

Hi,

although the snippet ripdad posted using StringIsSpace is correct I prefer to use StringStripWS which is a little bit faster, and while we are being overzealous, the snippet can also be used without the "$SearchRead And" part.

If StringStripWS($SearchRead, 8) Then ...

Edit: fixed AutoIt tags

Thank you!

Just what I needed.

Robjong, nice

Hi Robjong,

Regarding this snippet:

If StringStripWS($SearchRead, 8) Then ...

What if remaining contents of string ... is the number zero?

I don't know if you'd change anything - but this function is my shot at it:

If StringExists('0') Then MsgBox(0, "StringExists('0')", 1)
If StringExists(0) Then MsgBox(0, "StringExists(0)", 1)
;
Func StringExists($s_String, $iChars = 10);<-- number of characters to grab (including WS)
    Return StringLen(StringStripWS(StringLeft($s_String, $iChars), 8))
EndFunc

breakdown:

StringLeft - grabs a small sample to be tested. No need to test all of it.

StringStripWS - (same as intended)

StringLen - mainly determines if a zero exist.

thanks and take care!

--EDIT

I gave it some more thought for those that have to KNOW if it's a zero.

Somebody let me know if there's anything you'd change or do different or better. Thanks.

If StringExists('0') Then MsgBox(0, "StringExists('0')", '@extended=' & @extended & ', Return=1')
If StringExists(0) Then MsgBox(0, "StringExists(0)", '@extended=' & @extended & ', Return=1')
;
Func StringExists($s_String, $iChars = 10);<-- number of characters to grab (including WS)
    $s_String = StringStripWS(StringLeft($s_String, $iChars), 8)
    If StringLen($s_String) Then
        If $s_String = 0 Then
            Return SetError(0, 1, 1); string is a 0 - @extended=1, return=1
        Else
            Return SetError(0, 0, 1); is string - @extended=0, return=1
        EndIf
    EndIf
    Return SetError(0, 0, 0); no string - @extended=0, return=0
EndFunc
