What kind of textbox are you using, as it can contain underlined text?
Line breaks are easy. Store the lines in the database separated by Environment.NewLine. When you read the data to display on the web page, replace the Environment.NewLine occurances with the html code for line break, e.g. <br> or <br/>.

I think its a rich textbox so how should i replace the underlined words. i copy them from word into the rich textbox. But i'd like to make an editor like here on the forum but then in c#. The output should be a string off course that i can put in the database.

Then you will get the text in rtf format.
The rtf format is quite different from html, so there is no simple solution like just replacing some tags.
I don't know of any library that can convert rtf to html, but there probably exists something out there. I can't reach any search engines right now so you have to do the searching yourself.

I found a library who does this but its a trail version and i don't want to pay for this. Maybe an explanation how i can replace simple rtf to html. I already found how to replace new lines and spaces but i want to know how to convert underlined words too.

I am using Excel 11.0 object library. In MSDN I've found this example http://msdn2.microsoft.com/en-us/library/891ydsx9.aspx[^].
Excel opening, but on creating new workbook it fails and on string: 41 returns error:
_Workbook workbook = workbooks.Add(XlWBATemplate.xlWBATWorksheet);
, I receive error message
Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD))
What does this error mean? I am using Excel 2003
p.s. this example was the best what I've found ... so if someone have some links to working examples please write

I'm new to the printing aspects of .Net and have a question.
I have implemented the basic printing capabilities and have been able to direct a RichTextBox to a printer. I figured that when printing occured that same series of "drawing" routines called to display the text in the TextBox would be called again when drawing on the graphics object for the printer. However, what I have found is that my drawing methods are not called again to draw on the printer's graphics object (at least I assume so since the debugger dosen't break on my drawing code when printing).
So my question is how is printing done? Does .Net take the control's output and format it on the graphics object without actually calling my drawing code? If so, is there a way to choose what parts of the TextBox get printed or for that matter reformat the appearance of the text to make it look different than "what you see"?
Thanks,
Eric

Hi,
I'm overriding the RichTextBox class to add syntax-highlighting functionality (HTML, XML, PHP, C).
So far, I've been very successful. I have a working version with just a few bugs.
The only problem that I've run in to is that when the user opens a file, the process is very
slow. This is because to change the color of the text, I am using the RichTextBox's Select method
to select a range of text, and then setting the field SelectionColor. If I open a file with many lines,
this process takes a few seconds to complete. I notice that when I open a similar file in Visual Studio,
the syntax-highlighting is instantaneous.
So, I was wondering if there's a faster way to change the color of many portions of text in the RichTextBox (without selecting it first).
Is this possible using Windows Messages or Win32 Functions?
Thanks in advance.

There are no Win32 or Message functions you can use to speed this up. The problem is that you're using the worst control you can to do this. The RichTextBox does not lend itself well to syntax highlighting. Unfortunately, it's also the easiest to use without writing your own TextBox class to support this.
You may want to do some research by chekcing out these[^] articles to see if you can pick up a faster technique.

Can someone recommend a good resource on resolving thread timing issues?
I'm having an issue with a value that doesn't get set "quickly enough" in the debug version, but the release version works nicely.

You have to make sure that the value really is set before you try to use it. To be more specific is hard without knowing anything about what you are trying to do. The problem has nothing to do with timing, though, but the sharing of data between threads. The code shouldn't rely on one thread being ahead of the other, as that is very unpredictable.
Be most grateful that you found this bug already, though. You say that the release version works nicely, but I'm not so sure of that. Perhaps that also fails, only not so often.

I think I can speak for all of us when I say "Huh?"
What do you "timing issue"?
If you're trying to keep two threads in sync, you'll have to use some kind of synchronization mechinism. You absolutely cannot trust that two threads are going to run at exactly the same speed on every machine, let alone run after run on the same machine, or even under slightly differing conditions, like you've already discovered.
Off the top of my head, I'm guessing you'll have to implement some kind of "checkpoint" system, depending on what these threads are doing, where each checkpoint will only release when both threads make it to the same point. The down side of this is a lock condition where a thread waits forever for the other thread to get to the checkpoint, but the other thread has failed and aborted for some reason.

Never mind the unanswered question; I've solved the issue.

Hits the spot exactly... 
You know where this originates from? To my knowledge it's actually a quote from a Buffy the vampire slayer episode...

Hi all,
I have a form which is "heavy" , it have some pics and rich texts and stuff.
when i run the code "this.Show()" to display it starts drawing the form and the user can see the parts of the form being built.
i try to created it long time before showing it it still dont work.
the form is Borderless and it have a big picture on him with transperent color.
any ideas how to show it quick?
Ran.

There's usually no way to speed things up. Most people who have "heavy" forms are using 100's++ of controls and don't realize that creating a control is an expensive operation. Drawing all of them is also not cheap. The form is not compiled into an .EXE prebuilt with all the controls in place, ready to go. They are created added to the form's Controls collection when the instance of the form is created (calling the its constructor) and the constructor calls the form's InitializeComponents method.
I think the next most common problem is using images that are FAR bigger than they need to be for displaying at a normal resolution. For example, loading a 2,000x2,000 pixel image at 32bbp into a PictureBox that is only sized to 200x200. That's 10 times the image detail being put in a box that will never show it. Reduce the image size, if at all possible, to what is actually going to be shown.

hi
well that aint the case.
i do not have over resolution at all. i am using 3 smallpics and 1 piger one and another picture which is all over the form.
but the resolution is normal and i create it long time before showing it.
isnt there some way to tell him to praper the form as picture or something and show it all together..?
Ran.

Nope. You'd be going through the same problem just to get a snapshot of the form. You'd also have to wait until the thing draw the REAL form to get usable controls.
If you're only using a few controls and pics, then what's taking so long? Perhaps a code profile would be in order.
