Reqex leading white spaces

[three57m]

I am working on a project using richtextbox as usual.

I am trying to figure out a regex pattern to match the leading white spaces on each line of text.
I have messed with different variations of
the white space pattern with no success.

Tried:
.pattern = "\s" 'matches all white spaces so no good
.pattern = "\s\S" 'matches until hits non white space
which is better but still finds all white space between
each word in line and so no good.

and many others which I no longer remember.

Thanks in advance to any helpers.

[tt].pattern = "^\s*"[/tt]

I tried that one too but the result is only the first match in a line. so for example

line 1 = space space tab words
the pattern ^\s* only matches the first space
even with .global set to true

and that seems to be what i run into with every variation.

so to be clear, the needed result for

line 1 = space space tab word space word space ' would be
match = space space tab 'excluding the mathes between words
and at the end of the line.
and if possible continue to next line and do it all
again.

The closest I have come so far is pattern "\s(\S){1}"
with global set to false, and using the firstindex value
as the indicator of number of spaces or tabs. might need to go API on this one.

.Pattern = "(?:^|^\r)\s+"
.Global = True
.MultiLine = True
