From MSDN:
RichTextBox.LoadFile Method (String)
Loads a Rich Text Format (RTF) or standard ASCII text file into the RichTextBox control.
public void LoadFile(
string path
);
Parameters
path
The name and location of the file to load into the control.
Why not use this method? I'm pretty sure MS would have implemented the "best" way for this. Have you tried it maybe? What speed are you getting?
Cheers

well im more concerned with memory then speed actually.. my program standsat about 14mb of memory when all its embeded images are loaded (.exe size is 600kb) but when i open this 7.83mb file of just text... all of a sudden the program is taking 50mb of memory... i know that before i close the stream reader i use the StreamReader.Flush() too clear its buffer.....anyways thats my concern... any ideas? there are no other codes be excuted when it opens... if you want the full source too look at ill send it k leppie ? (1150 lines)

There are some overloads to that function that can take a stream as a parameter. That mite help.

how can i apply that to this leppie ?
(LoadFileOnStart Comes from command line args via drag and drop (like notepad does when you click on a .Txt file)
<br />
if(LoadFileOnStart.ToLower().EndsWith("rtf")|LoadFileOnStart.ToLower().EndsWith("doc")){<br />
using (StreamReader r = new StreamReader(LoadFileOnStart,System.Text.Encoding.Default)){<br />
MainTextArea.Rtf = r.ReadToEnd();<br />
r.Close();<br />
}<br />
}<br />
i have been reading about memory optimization on msdn and i think i can rewrite this program agian and get better performance....i just wrote it so i could figure out command line args (i can now replace this program with notepad and it loads the file on startup through command args) i also wrote it too use reflection...which i figured out...anyways the point is it has no clear direction allthough the save function is actually really cool anyways.....

Can anyone recommend a fast way to send large files to a webservice?
To my knowledge DIME does support chunking, but proxy service and SOAP do
not automatically. I think the solution here is to chunk files into
DIME records and then modify each SOAP message to append the record as an
attachment. I couldnt find any sample code, but the article below
discusses the modifying the soap envelope to add the dime record.
Is there other ways for the WSDK or SOAP3.0 make multiple HTTP calls for each record within a single DIME message?
Id be interested in any other comments on this ..

I've just started playing with c# and created a simple control which inherits the textbox control.
I can hide all properties relating to multilines as the control will never do this, by overriding the property and setting [Browsable(false)].
My question is, is there a way to also stop intellisense picking up these hidden properties, eg
usrTextBox.AcceptsTab cannot be seen on the properties page but can be pickup up within the body of the code using usrTextBox.?????
Thanks

Is it possible to tell if a control is being designed by the windows form designer? As i will need to render it differently in that situation.

Hello,
I'm new to C#.NET programming and I have little knowledge on C++. I'm trying to write a project which will convert a decimal number to hex and hex to decimal. I tried "Convert.ToInt" but couldn't get the result.
If anyone would help me about this problem, I would be appreciate it very much.
Thanks!

This should work:
string ToHex(int number)
{
return number.ToString("X");
}
int FromHex(string number)
{
return int.Parse(number,
System.Globalization.NumberStyles.HexNumber);
}

I've got one that I wrote a while ago using straight C++ so I was thinking of porting either it or Tidy - but was hoping someone else had done the legwork before me.

Hi , ive asked this before , but does ANYONE know how to make a borderless window behave like a tooltip?
meaning , it should not steal focus from the app that shows it (grayout the apps caption)
i need to be able to place controls on the 'tooltip' but they dont need to be able to hold focus , just as long as i can click them and the click events work...
currently im doing some nasty wndproc hack , scanning for the wm_ncactivate message , and setting focus back to the parent window... but this causes the parents caption to redraw , so there is some minor flicker (but still annoying)
any idea?
//Roger

If you're using Windows 2000 or higher, you can override the CreateParams property, and add WS_EX_NOACTIVATE to the ExStyle property:
class TooltipForm : Form
{
...
protected const int WS_EX_NOACTIVATE = 0x08000000;
protected override CreateParams CreateParams
{
get
{
CreateParams cp = base.CreateParams;
cp.ExStyle |= WS_EX_NOACTIVATE;
return cp;
}
}
}

using win2k and c# , setting the window to "Topmost=true"
it still steal focus..

Excuse-me for my stupid question, In WebForm, I would like to create a button that allow to open html page.(link with parameter ex: qsdf.asp?Text=tete) in the same browser (and other browser). How can I do that?

In your event handler for your Button you can Response.Write your javascript code to load a new window and change the location of your current browser. This gives you a dynamic effect.
js references
window.open, href.location
example:
public void OnClickButton1(object sender, EventArgs e){<br />
Response.Write("<javascript>window.open("www.codeproject.com");</javascript> );<br />
<br />
}
