My input text is:
"the quick ${var1:a=b,c=d,e=f} brown fox ${var2:g=h,i=j,k=l}"
var1,var2 is a "variable"
a=b is considered a "parameter".
I can have any number of variables in the input string
I can have from 0 to any parameters (i.e. ${var1} is allowed)
My end result is I want to split as:
var1|a|b|c|d|e|f for the first match
var2|g|h|i|j|k|l for the 2nd match
The regex I'm using is:
\${([A-Za-z]+)(: ([A-Za-z]+)=([A-Za-z0-9]+)(,([A-Za-z]+)=([A-Za-z0-9]+))*)*} <=== NO SPACE after the colon (preventing smiley)
Right now I'm getting:
var1|a|b|e|f (and a few other groups I don't care about), but for discussion, the full split is: |var1|:a=b,c=d,e=f|a|b|,e=f|e|f
The problem is, it's grouping a&b and e&f, but its skipping c&d for some reason... if I add a 4th parameter, now it skips e&f too. I.e. it only shows the FIRST and LAST param.
What's going on?

You may be trying to do too much at once. I'd either make it multiple pass or use code.
One other thing I'll mention, is that often with this sort of thing you need to scan right-to-left.

Hmm... apparently, what I'm seeing is "expected" behavior. Standard regex behavior is to only keep the last group. I think that's insane and apparently so did the .Net folks as they have the only regex engine which keeps all capture groups. Thanks!

When looking at another Regex question today, Regular Expression, specific seq[^] , I learned something new.
A pattern like (aB)* may match multiple times and only the final match will be captured, but you can capture the whole thing too ((aB)*).

The .Net regex engine is "special" as it's the only regex engine in the known universe that doesn't throw away intermediate captures. If you look at the Group object that captured the last occurrence of the group in question, there is a Captures property. They give you the intermediate captures in that collection.
(aB)* will match aBaB, but it will only give you 1 aB. If you look in the Captures property, it'll give you the 2 you are after.
((aB)*) will match aBaB, but it will still only give you 1 aB. It will also give you aBaB which is not what you really want.

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.

Is it an Int32 in the table-definition? Or did you mean an Int32-column in the DGV?
What does your query look like? Can you run a "SHOW CREATE TABLE" query on the table and dump the result here?

If you can't read my code, try converting it here[^]

I'm uncertain what you mean by your question.
Are you saying it is displaying as byte[] and you don't want it to?
Or you want it to display as byte[] and it isn't?

Is this from an article? If it is, you should really post this request on the article itself. The chances of the author happening on by this post and seeing your question is very small.

Did you try typing that into Google first? It's amazing what you'll find by using a search engine.

Steady on there!
That's pretty damn close to the OP actually doing some work for himself!

That made no sense at all. I have no idea what you're trying to say.
