Network Problem Overview snouto4-Feb-06 0:45 snouto 4-Feb-06 0:45  hello folks. if my user is behind a firewall that only allows connection through port 80 how can i make my application get binary data and respond to the outside world also in binary data through port 80 . How can my application distinguish the binary content coming from http request from internet explorer (suppose the user is currently browsing the internet and opening my client application). How can i distinguish between the data comes from my server and the data comes from any webserver during browsing through port 80. Thanks Everybody.

RFC[^] for HTTP defines the format of a HTTP header, so you can look for it to identify requests from a web browser.

I have build a structure up where the ContectMenu is static and where i hoped to use a database with ToolStripMenuItem, and it works quite ok to add an item with ToolStripMenuItem.DropDownItems.Add(readdba.GetString(1) but do any have an idea on how to get either an index or the name of the Contextmenu field that comes from the database when it is selected? Cheers, Marker string to html stijnbe3-Feb-06 23:49 stijnbe 3-Feb-06 23:49  I made a website in asp.net. but now i want to make a program in c# to add news,... in the database but this should be in html format. Does anybody now how i can format a textbox to html. gtz stijn Re: string to html Guffa4-Feb-06 0:31 Guffa 4-Feb-06 0:31  What is it in the text that you need in html format? If the string just has to be html encoded, don't do that before you put it in the database. Do that when you read the data and display it in the web page. Use the Server.HtmlEncode method to encode the string. --- b { font-weight: normal; } Re: string to html stijnbe4-Feb-06 1:15 stijnbe 4-Feb-06 1:15  The problem is when something is underlined or there is a new line in the textbox the asp page should also display this. gtz stijn Re: string to html Guffa4-Feb-06 2:06 Guffa 4-Feb-06 2:06  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/>. --- b { font-weight: normal; } Re: string to html stijnbe4-Feb-06 4:29 stijnbe 4-Feb-06 4:29  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. gtz stijn Re: string to html Guffa4-Feb-06 6:33 Guffa 4-Feb-06 6:33  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. --- b { font-weight: normal; } Re: string to html stijnbe4-Feb-06 21:50 stijnbe 4-Feb-06 21:50  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. gtz stijnbe Excel, how to add workbook? tray_gator3-Feb-06 23:26 tray_gator 3-Feb-06 23:26  I am using Excel 11.0 object library.

It contain an image, a label and sometime a linklabel. On the right side there is a scrollbar. So how can i create controlls like that? Is it overloaded a simple multiline textbox or what? thanks if someone try with me to get an answer Re: How to create registry object like Skype Guffa3-Feb-06 22:53 Guffa 3-Feb-06 22:53  You asked the exact same question yesterday. Don't spam the forum. --- b { font-weight: normal; } Printing question Beringer3-Feb-06 19:04 Beringer 3-Feb-06 19:04  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"?

Syntax-Hilighting DigitalKing3-Feb-06 15:24 DigitalKing 3-Feb-06 15:24  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. DigitalKing Re: Syntax-Hilighting Dave Kreskowiak3-Feb-06 16:03 Dave Kreskowiak 3-Feb-06 16:03  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.

Everybody Human Knowledge belongs to the world. Re: Proxy Problem Please help Dave Kreskowiak3-Feb-06 13:43 Dave Kreskowiak 3-Feb-06 13:43  Well, you can start by reading Proxy Detection - Take the Burden Off Users with Automatic Configuration in .NET[^] on MSDN. You can also check into implementing your own discovery mechanism by reading the Web Proxy Auto-Discovery Protocol[^] draft document. This will NOT be easy to implement on your own and your proxy might not even support this.

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. -- I've killed again, haven't I? Re: Thread Timing Issues (Debug/Release) Guffa3-Feb-06 13:16 Guffa 3-Feb-06 13:16  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. --- b { font-weight: normal; } Re: Thread Timing Issues (Debug/Release) Dave Kreskowiak3-Feb-06 13:18 Dave Kreskowiak 3-Feb-06 13:18  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.
