Hello,
I want to write a _very_ simple text parser that would replace a
string like:
"This is text with /italics/, *bold* and _underline_."
and generate automatically something like this:
"This is text with <i>italics</i>, <b>bold</b> and <span
class="underlin e">underline </span>."
I've found a lot of code snippets explaining how to do BBCode, but
BBCode has different opening and closing pseudo-tags. In my example,
the opening and closing tags are the same (either /, * or _). So I
need something slightly more intelligent that would count the number
of /, * or _ tags, see if that number is even or odd and decide
accordingly if it must replace the char with an opening or closing
tag. (I hope my wording makes sense. It's very clear in my head :-D)
How would you implement that? I reckon it can't be hard, but I just
can't figure how to do it right now!
Thanks for any insight! 3 3948

WOW those perl regex are powerful! Every now and then I tell me I
should dig deeper and really understand them (beyond the basic stuff I
already know). This is pure and deep beauty! Now I want to learn them

Thanks, thanks and thanks again.

Hi,
What I try to do is to search a text for html tags.
Why. Because I want to use nl2br on the text, but since this command add
br instead of all /n it is not a nice thing to add t.x. a html list inside
the text. Of course it is possible to add the list and remove all space
between li tags, but this is not so readable to the writer.
What I try to do is also to add nl only in the plain text and inside li

Can I create an array of tags by assigning same name to these tags?
For example, I have two <p> tags with the same name t1. But

I could use some regular expression help. I'm trying to create a

then will insert html tags accordingly.
So, the user writes up a document in word that contains instances of

Okay,
Assinging the font and its style (bold, italic etc.) using the font dialog
is easy such as:
FontDialog1.ShowDialog()
txtEmailBody.SelectionFont = FontDialog1.Font
But how does one change the selected text to bold, italic or underlined
without using the font dialog?

Ok, I am creating a string to go into a RTB. Is there any code or tags I can create within the string so that I can Bolden or Italicize certain words?
I would normally assume no way until I saw that VStudio automatically changes my URL addresses into real links. Sure would be nice to be able to tag certain words as bold or italics.....
ANY easy way to do this?

Im a little bit stuck on how to change a cell in a datagridview to bold without affecting any of the other attributes of the cell, such as underline, italic etc.
This is what I thought would work but doesn't
foreach (DataGridViewCell cell in grid.SelectedCells)
{
cell.Style.Font = new Font(cell.Style.Font, FontStyle.Bold);
}
This does change it to bold but takes out italics and underline.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
