Regex question

[rcmaehl]

Currently I have

Switch StringLen($Serial)
        Case 0
            Return "Please Enter a Serial #"
        Case 1 To 6
            Return "UNKNOWN or INCORRECT"
        Case 7
            Select
                Case StringLeft($Serial, 2) = "79"
                    $Valid = "Device 1"
                Case StringLeft($Serial, 3) = "350"
                    $Valid = "Device 2"
                Case StringRegExp($Serial, "72[HR](.*)") ; Match 72H and 72R
                    $Valid = "Device 3"
                Case Else
                    $Valid = "UNKNOWN or INCORRECT"
            EndSelect
        Case 8
            Select
                Case StringRegExp($Serial, "\d[A-Z](.*)") ; Match a Digit (0-9), then a letter
                    $Valid = "Device 4 short format"
                Case Else
                    $Valid = "UNKNOWN or INCORRECT"
            EndSelect
    EndSwitch

Which I'm using to match a number followed by a letter then any number of digits up to a string length of 8 characters.

However I don't want it to match strings such as 1234A123 only 1D123456

Is there anyway to do this using a flag or am I limited to having to use StringLeft()?

Looks like a contradiction here: 1D123456 matches the first sentence. 1234A123 would also match if one interprets "a number" literally, whereas I believe you meant "a digit".

What about "^\d[A-Z]\d{0,6}" assuming "any number" really means what it says.

That works too, I was just hoping that there was a simple way to do "If Entire String Matches Regex Return True, Otherwise Return False"

I don't get it. The contradiction is still there.

You speak of case 8, correct?

Then what do you allow after the digit followed by the letter followed by any number of digits? Isn't that also contradictory with length = 8?

Found what I was looking for

StringRegExp($Serial, "\A\d[A-Z]\d{0,6}$")

Case 8 doesn't matter I just needed it to Return True if the above was met. I realize now that what I posted was confusing as I said any number of digits but the code contradicted me.
