Regex: how do I replace just a part of the pattern I'm matching?

Question

What I'm thinking of is something like matching a lower-case character followed by a full stop, then just replacing the full stop with a comma. So something like

[a-z]\.

to

[a-z],

But I can't figure out how to get the regex to 'ignore' the lower-case character. I'm working in VB 6, if that matters.

Anyone?

Sorry, I was unclear. Currently what I have will replace e.g.

h.

with literally

[a-z],

I need to keep the h, or whatever other lower-case character is there, the same.

Answer 1

In Perl, you would write
$line =~ s/([a-z])\./$1,/g;
$1 refers to whatever was matched in the parentheses. I'm not familiar with with what's available in VB6.

Oops, forgot about lookbehind:
(?<=[a-z])\. matches a "." preceded by a lower case letter, without making the letter part of the match. Again, works in Perl, not sure about VB.

Answer 2

Er...

Why would you be wishing to ignore the lower case
character, when that is exactly what you are trying
to match??

What you have written,

[a-z]\.

will match *any* lower case character which is
followed by a full stop.

All you need do is specify the format for the replacement text, as in,

[a-z]\,

Since I've never used Visual Basic, I can't tell you
what the command syntax would be for replacement
rather than match. Over to you there.

You can have the expression in Perl if you like? But,
its a pretty straightforward swap, really. ;o)

Anyway, HTH.

India had a distinctive to suitable journey after Australia's first innings batting,i presumed it replaced into solid first innings from Aussies yet India scored so quickly attributable to Dhawan and co and Australia's 2d innings capitulation that befell so without postpone on the final day won't be able to be defined even with the help of Ian Chappell.Batting for India clicked so properly in this sequence,that they had a distinctive to suitable journey.Australia could desire to've drawn this journey yet they ended up dropping on the final day attributable to a pair poor batting in 2d innings.

Answer 4

if you have a string in VB6 use the LCase function
Ex

dim s1 as string
s1="AbCdE"
dim s2 as string
s2="ABCDE"
if LCase(s1)=LCase(s2) then
msgbox (s1 & " = " & s2)
else
msgbox "You Fail at Life."
end if

vI have been searching for a long time to try to find a calendar application like the one on a now-abandoned site that a local ministry group had put up a couple of years ago. The calendar consisted of hour-long blocks of time around the clock and people would sign up to commit to pray for local churches during the period for which they were signed up, and they would receive notification e-mails as reminders before the time for which they signed up. I've tried to reach the programmer who put the site together, but he doesn't live in this area, and the people who worked with him to set up the site aren't sure where the application came from. If any of you could tell me where I might find an application like the one at this link, I would be very grateful:
