FileRead Case sensitive

[david1337]

Hi guys

I hope you can help me out

I have a script that checks for the current user's loginname in different txt files.
If the current user's loginname is found in one of the txt files, the script reacts based on that.

The text files look something like this:

dle
oej
zaq
oei

 

(different usernames)

 

This is an example of the script:

$username = @UserName    ;pulls username that is logged in

$Dir = "C:\Test\"

Global $Custom[] = ["text01", "text02", "text03", "text04"]


;CHECK LISTS
For $i = 0 To UBound($Custom) - 1

$CustomFile = FileOpen($Dir & $Custom[$i] & ".txt", 0)
$Readtxt = FileRead($CustomFile)
FileClose($CustomFile)

If StringRegExp($Readtxt, $username) Then

do this and that...

EndIf
Next

It works perfectly if the user logs in as xxxx or XXXX (Both lower and upper case characters)
So the FileRead function doesn't seem to be case sensitive.
But if the user logs in as xxXx (mix of lower and upper case characters), then the username is not recognized in the txt file.

 

Does anyone have a suggestion on how I can fix this?

Thanks in advance!

david1337,

Use StringUpper/Lower on both the file content and the user name - or use the case insensitive flag "(?i)" in your RegEx  pattern.

Improved visiblity of RegEx flag

[Exit]

If StringRegExp(StringLower($Readtxt), StringLower($username)) Then

 

Edit: Melba23 had the better answer.

Hi guys

Thanks for your answer!

Exit's soloution --> "If StringRegExp(StringLower($Readtxt), StringLower($username))"  seems to have done the trick, which confuses me :)?

Melba you tell me in your post that I should also include a StringUpper - why does it work without that?

david1337,

You can use either StringUpper or StringLower - just as long as you use the same one on both elements. But making the RegEx case-insensitive as I suggested would be much the better solution.

Melba23,

Ahh okay I get it That's why it works.

 

Anyway, I will try to figure out to how to make the RegEx case-insensitive instead then, when Melba himself recommends it!

As always, thank you for taking your time to explain things!

I showed you above - add (?i) at the start of the pattern.

Hint...$readtxt is your patern.  Concatenate the case modifier in front of it...

[Melba23]

kylomas,

The pattern is "$username".
