Hi all,

i have 3 projects in my solution suppose Project1, Project2...
and in the startup project i.e. in Project1 i have an XML file which
i want to access in another project i.e. Project3.
i can access it using the physical path for now, but
i want to use the virtual path for accessing that because on
the clients end the file may be stored on any partition of the System which is unknown.

can anyone tell me what should i use to access the file?

Thanks,
Pramod

Links in RichTextBox

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

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);
}
