Hi all,
I want to insert a folder path as a link in the RIchtextbox,
so when the user clicks on that link the folder should be opened.
I have set this using the "file" protocol but
the folder path is c:\Documents and settings\
here when i handle the linkclicked event
and try to get the path from the e.linktext property
i only displays "c:\Documents"
i.e. only upto the first space character.
How do i get rid of this?
Thanks & Regards,

Hello
AFAIK URLs don't support actual spaces. You'd have to substitute spaces with "%20".
eg.
Documents and settings => file:///C:\Documents%20and%20Settings
If you can change the text -not the link- it won't matter as long as the link itself goes without spaces.

Thanks for the quick reply,
When i use the "%20" to replace with the spaces in the path,
The following is displayed "file:///c:\Documents%20and%20settings\foldername"
and the link does not open, it gives and error.
i don't want the word "file" to be displayed as well
the link should look like
C:\Documents and settings\foldername
how do i do that?
Thanks & Regards,

What is the error message?

It's possible, but I don't think it's worth it!! It will take some effort.
1- Make a LinkLabel object and initialize it.
2- Add it to MyRichTextBox object.
3- Set it's location according to your text -don't worry about scrolling-.
4- Handle the LinkLabel's own click event rather than the RichTextBox's event.
Sample code:
LinkLabel MyLink;
private void Form1_Load(object sender, EventArgs e)
{
MyLink = new LinkLabel();
MyLink.Text = "This is a link";
MyLink.Links.Add(0, MyLink.Text.Length, @"file:///C:\Documents%20and%20Settings");
MyLink.Click += new EventHandler(MyLink_Click);
MyRichTextBox.Controls.Add(MyLink);
}
void MyLink_Click(object sender, EventArgs e)
{
Process.Start(MyLink.Links[0].LinkData.ToString());
}
I hope this helps!!
Regards

Thanks, but i have used a "_" (underscore) character.
and later replaced it with a space while opening the link,
BUt how do i remove the file keyword?

Hello
Your title was quite clear in stating that you are facing a problem with images -and this is the C# forum BTW. Welcome -
Yet, your post itself didn't specify what exactly are you stuck with??

plz help in converting code from matlab to C#, i m sending u code as i told im working in image processing , ihave done all work in matlab but now i hve convert it in to C# Code is below
%Reading image file and storing it in a variable.

Hello
I've never worked in Matlab -I'm a C++, C# developer-, so the code above is very unfamiliar. Yet I can get a grasp of what you are trying to do.
One Question:
Did you ever program in C#??
If you're asking someone to build your program from the scratch!! It's highly unlikely to find him here!! Sorry!

Hello,
I am aware of that I can open a website using the following snippet using MS IE,
System.Diagnostics.Process.Start("iexplore", "http://www.google.com");
But I dont want to specify Internet Explorer, I want to open the link using any installed default website explorer of the user.
Would anyone please give me an idea.
Thanks

In .NET 2.0 you can do this....
Help.ShowHelp(this, "http://www.google.com");

Hello
You can also do that in .Net 1.0 and 1.1 frameworks. Simply don't specify your application:
Process.Start("http://www.google.com.eg");
This way you are telling the "Windows Explorer" to open this "Document" -whether it's a website, pdf, image, etc...-. Windows Explorer doesn't open anything by itslef, rather it opens the default viewer associated with this type of "Document". In our case it will open the default web browser.
BTW: I use FireFox. And it works!

Hi Nader,

Hi, folks!
I've made a sub-class of the System.Windows.Forms.RichTextBox called "MyRtfBox". Within my rtf box, I want to add a few properties which allow me to directly access some of the advanced properties of the rtf textbox, such as line count, getting the scrollbar thumb's position, etc. I'm glad to say that I've figured all of that out, EXCEPT for how to get and set the display rectangle using Windows Forms Messages!
I've looked all over the web and can't find any articles anywhere in C# that show how to use these two Messages. The examples I've seen in C++ and VB don't seem to translate well to C#. Does anyone have a clue?
When it's all set and done, I'd like to have a sub-classed RTF box with this public property...
//Taken from the Windows constants list.
private const int EM_GETRECT = 0x00b2;
private const int EM_SETRECT = 0x00b3;
public Rectangle DisplayRect
{
get
{
Rectangle rect = new Rectangle();
//Send a message to Windows somehow!
return rect;
}
set
{
//Send a message to Windows using the given Rectangle parameter.
}
}
Many thanks!!
Anthony

Okay, don't get hung up on the fact that I called the public property, "DisplayRect". I know there's already a public property on RTF boxes called DisplayRectangle.
The point of this exercise is to understand how to use the 2 Windows constants in sending messages to Windows asking for this info, and then setting a new value. Since there doesn't seem to be any other C#-specific examples out there in the world, this would be *really* useful!
Thanks!
Anthony

Hi!
I'd suppose you can use EM_GETRECT and EM_SETRECT just like any other windows message sent to your RTB.
The declaration of SendMessage is something like this:
[DllImport("user32.dll")]
private static extern int SendMessage(IntPtr hWnd, int msg, IntPtr wPar, IntPtr lPar);Then you can use this function to send the messages to your RTB. The last parameter (lPar) is used for the rectangle. You can use the Marshal.StructureToPtr() and Marshal.PtrToStructure() methods to transfer the rectangle data to your working structures.
That should do the trick...
Regards,
mav

I got an app where I use the backgroundworker and when it's done it fires off the BackgroundWorkerCompleted event. Which is all good. but I need to reused the object later on. I get an exception that the BackgroundWorker has already completed.
So I tried myBackgroundWorker = new BackgroundWorker(); but none of the events are hooked up any more and it just sits there.
Is there anyway to reset it? or do I have to set all the properties each time I use it?

You must reconnect the events, this is a new instance of BackgroundWorker. You can't rest the original because the thread has already completed its work and has been returned to the pool.
only two letters away from being an asset

If you're re-starting the worker with RunWorkerAsync() the only exception would be InvalidOperationException, which means the worker is still running (IsBusy is true).
What exception are you getting?
