Main advice: Don't use a RichTextBox for syntax highlighting.
For each SelectionColor = ... call, the whole content of the RTB is streamed out to RTF, modified and then streamed back in => enormous overhead.
Recently there have been 2 articles here on syntax highlighting (try the search function). I think you should read them and the readers' comments. I'm quite sure that'll help you.

I've downloaded a source project by http://www.codeproject.com/cs/media/CsTranspTutorial3.asp
i've tried to build the project and it create automatically a .dll file.
I don't know looking all the code where it is specified to create that .dll
Where is specified, if does someone know?
How does it need?
Thanks.

It's specified by the project type. You can import the dll to use it in your own code.
If you're this lost, you may do well to stop and understand the code you're using, before using it.

Hi, please i have a little problem in doing this sequence of image processing:
1- Gray scale an image
2- selecting a region of intensities e.g.(form 75 to 150)
3- then, i want to split this region in a new bitmap image.
4- finally, assigning a new color for this new region like red only....(my target)
thanks

What part are you stuck on ? My image processing articles show how to make greyscale, if you want to do it manually. The code also shows how to modify pixels directly. However, how will you do this unless your region is square ? Surely these intensities will be scattered throughout the image, in an irregular pattern ?

Hi, thanks. But my target is to split some selected pixels from the image and put it in a new one, then, assigning a new color to them.
i don't know how to assign a new pixel color, or how to split them.

OK, so you need to take the portion of the image you want, and create a new one with those values. That's bog easy - you just create a new Image, and draw the part of the image you want from the old onto the new. The hard bit is if your desired area is not a rectangle, you'll get some bits you didn't want.

What do you mean by split ? What is this application doing ? You can change the colour a number of ways.
1. SetPixel. This is slow
2. Draw onto the image. That's what the brushes and pens are for. Probably also too slow
3. Direct pixel access, which again means you should read my image processing articles.

Hey there,
I have an application which lists the following menu options "File" " View" "Help" etc.
And ofcourse within each of these is a further list of options. I want to write an application which will automatically nagivate through this menu ... As an example...suppose I want to go to View->Text Size -> Normal, I can do so through my application at the click of a button.
Is anyone aware of the kind of messages I could send or provide an example of any such code you may have.
Regards,
Abhishek

hey,
thanks for the reply however I am trying to navigate through a different programs menu using my application.

I dont have the SDK but I could use Microsoft Depends to get a idea of the function being called.

Your looking for SendKeys[^]. Which, BTW, is a problematic way to control another application. Since the focus can shift from one window to another without any warning, your keystrokes could end up going to the wrong application. Also, I hope your VB app that your controlling has keyboard shortcuts define for all the menu choices...

How would I do this?
I have 3 files that have to be put in certian places on a harddrive. I want to make a program that will do this automatically.
Is there something out there that I could use already? I was thinking maybe a install wizard or something like that, but i can find one that I like.
Thanks
Chad

Can you explain a bit more? what are the files? exactly at what places? hardcoded? or depend on the specific machine configuration? Windows special folders?
We need more information in order to help you. If you have the specific folders and filenames, FileInfo.MoveTo[^] might help you.

I know how to use the System.Web.Mail class to send mail through smtp but I want to use this for error reporting for one of my programs and I don't have a public smtp server. Are there free smtp servers that I can relay this through or is there a better way to report errors to me?
Thanks,
Rob Tomson

what about your ISP's, you would probably need SMTP auth though if the ppl running your app are not on your ISP's domain. this would be a maintenance nightmare if you hade more than a few apps distributed and you changed ISP's
Im sure there *are not* public SMTP's as the internet has more than enough spam already.
what about just ftp'ing it to you from the remote site, or http tunnelling ?

thanks for the reply. what http commands would I use to send the mail? I tried quickly searching google but it was talking about ssh tunneling, is this what you're talking about?

I've created a program to track my tasks I have to do at work. I use a listview to display the tasks. Some of my tasks require certain steps be followed before I can complete them.
I plan on adding the ability to add requirements to a task. But, here's my idea! I would like to somehow be able to have a ProgressBar that is somewhat transparent across the entire row of each task that shows the progress of that task. I'm trying to figure out if it's possible to have a 1/2 transparent progressbar display on top of each of my tasks. Is it possible? How can I do this?

Howdy,
Sorry for the basic question...moving over to C# and having trouble finding an alternate to the following...
//constructor
public foo(int, string[])
{
//blah
}
...
foo bar = new foo(1,{"1","2","3","4"});
Any help &/or suggestion would be greatly appreciated. Thanks!

Sorry, jumped the gun there a little bit...
The issue I am having is that C# doesn't seem to like this syntax. I could easily get around it by defining my own string[] w/ values prior to creating a new foo object. But I'm hoping to just be able to define the string[] on the fly as indicated in the bold, italicized text above...thanks!
~rcurrie

Try this:
foo bar = new foo(1, new string[] {"1", "2", "3", "4"});

Much appreciated Robert, thanks so much!

hi all.
I just need to ask one question !
how can split the incoming string into string array by finite small string i know that split method for normal string can split the string into string array but with specific character not exceed one character like the following
--------------------------------------
<br />
using System;<br />
namespace snouto<br />
{<br />
class stringargs<br />
{<br />
static void Main(string[] args)<br />
{<br />
string string1 = "hi#thatisme#yeah";<br />
char[] splitters = {'#'};<br />
string[] separated = string1.split(splitters);<br />
}<br />
In the above code i split my string into string array using # character format but if i want to split my string by using another string like "snouto" in tha above string
<br />
string string1 = "hisnoutoThatismesnoutoYeah";<br />
how can i split the above string using snouto which repeated inside the string
Please help
