I have not hardly cut my teeth on RegEx yet. What I am trying to figure out is a way to replace line feeds with < BR >'s but not between of < PRE > and < /PRE > tags. Any easy answer to do with with RegEx?
This is possible using regex with a multi-line expression, but if you're working with HTML you probably shouldn't do this. What if an element spans multiple lines and you replace the new line with <BR>? You cause HTML errors that browsers will choke on. Putting breaks after inline images would also be bad, since it would screw up the flow of the image with the paragraph that surrounds it. There are several other cases where this would be bad, too.
To better help you solve this problem, let me ask why you want to do this? If you're generating the HTML files, it would be better to do this in the first place, or if you want to modify the files you should use a good HTML reader (unfortunately there isn't a specific reader in the base class library for HTML, though there is the HtmlTextWriter).
I have text input via a multipe line TextBox and onces I Server.HTMLEncode it, I need to add the <BR>s for linefeeds. In a specially flagged section though I will be using a < Pre > tag and it requires linefeeds instead of the <BR>s. There are no HTML tags in any of the text entered, just a special tag which I will replace with < Pre > section.
This is for my HintsAndTips.com site that I will FINALLY be launching tonight (and hopefully, people will like posting tips to share since there are only a couple at the moment ). When they post their tips I have to have a special section for things such as code that you do not want text wraping and handle this through a special tag people can use to enclose that section. It is replaced with a scrollable div and a pre tag (to be more compatible with old IEs or would just use the "white-space" css feature).
At the moment I have it replacing all the linefeeds with <BR>s and they look okay in the browser, but the < Pre > does not handle blank lines and stacks the lines on top of each other.
I will be providing a better method of composing tips in the near future, but just needed something to allow people to display text that is much wider then the area provided and a scrollable div works great for that. Kind of like on CP when someone does not format an article good and it takes three monitors to view it horizonally Did not want that happening
Here is an example of tip with the Pre section I was referring to:
The think that I can see is BinaryReader is for reading but you create FileStream in ReadWrite mode,change it to Read mode,and for writng into create another stream. If it didn't solved then tell what error you encounter. Also in msdn there are some samples for writing into and reading from file in BinaryReader page,you can check it.
This time, click the "Do not treat <'s as HTML tags" checkbox.
I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf.

There are some shortcuts, too. If a param takes an address of a struct, rather than make several unsafe calls from the System.Runtime.InteropServices namespace, you can instead overload SendMessage. For instance, the TVM_SETITEM message for a TreeView Common Control (which System.Windows.Forms.TreeView encapsulates) requires the address of an <code>LPTVITEM for the lParam. You could overload SendMessage like so:
Thank you very much, but in the article you posted I only found how to get running processes, I need to get the applications, like in the first Window in Windows Task Manager.
I searched a lot in CodeProject, but I didn't find nothing really usefull.
Thanks anyway, the article is very interesting
