I know this might be a stretch but I'm trying to insert an image into a RichTextBox and make it a link.
I currently insert an image using the methods presented by, Khendys Gordon: www.codeproject.com/cs/miscctrl/csexrichtextbox.asp
and am successful in doing so. But when I actually go to set the inserted image string as a link, the image isn't displayed.
So I'm begining to think it isn't possible but thought I would ask others.
Thanks,
Eric

if u can write event handlers for that image it would be easy
u can write the Mouse Hover event and change the cursor to Hand in this event
and in the click event of the image u can redirect to the link that u want

for this u need to create a windows form of that size,
remove the title bar of the form
use a timer control
get the work area of the screen by using the screen.GetWorkingArea
and on every tick of the timer u can change the location of the form to appear as if it is poping up and after some time again change the form location so that the popup window goes down and hides
Regards,
Pramod

as u have written i have done all the things. i am getting problem in redrawing the form . at every tick the i m changing the position of the form.but form is not gettin drawn properly. i refer the code given in the link which i have send eailier. i use the following code for redraw the form
protected override void OnPaintBackground(PaintEventArgs pea)
{
Graphics grfx = pea.Graphics;
grfx.PageUnit = GraphicsUnit.Pixel;
Graphics offScreenGraphics;
Bitmap offscreenBitmap;
offscreenBitmap = new Bitmap(BackgroundBitmap.Width, BackgroundBitmap.Height);
offScreenGraphics = Graphics.FromImage(offscreenBitmap);
if (BackgroundBitmap != null)
{
/* problem is here actually i don'nt know which method i have to
used here in this example they are using DrawImage method.which is basically for an Image.for form i didn't understand which method i should use */
offScreenGraphics.DrawImage(BackgroundBitmap, 0, 0, BackgroundBitmap.Width, BackgroundBitmap.Height);
}
grfx.DrawImage(offscreenBitmap, 0, 0);
}

When I want my file to be hidden, I simply use this System.IO.File.SetAttributes(str filepath, FileAttributes.Hidden) .
But what about Directory, How can I set my directory to be hidden, I dont find any SetAttributes method for directory !
Any helps ???
|
|
|
|
|
DirectoryInfo d = new DirectoryInfo(@"path\to\your\directory");
d.Attributes |= FileAttributes.Hidden;
|
|
|
|
|
Great ... It works ! Thank you !
|
|
|
|
|
Hello,
Use DirectoryInfo class's Attributes property.

Hi all,
i am using Arraylist to store some values
i add the values using the list.Add() method
but when i try to access the values from the list
it gives me exception saying that
object Reference not set to an instance of an object
i try to retrieve the value in the following form
string ss = urls[x].ToString();
i have even tried
string ss = (string) urls[x];
Can anyone help me out of this?
Thanks,
Pramod

This error means one of two things. Either:
You have not initilized the ArrayList
or
You are trying to access an element of the list that does not exist (the index is less than 0 or greater than the number of elements in the list minus one)
|
|
|
|
|
sorry that's not the case
i have initialized the Arraylist
also this exceptions comes sometimes
Actually it is in a thread and the values are retrieved for
the first 2 threads but when some thread tries to access the exception occurs
i have even checked the index, it is within the bounds and the values exist
the values are displayed in the watch window
don't actually know wht's happening?
Thanks,
Pramod
