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

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);

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)

Re: ArrayList Problem

AB77716-Mar-06 19:11

6-Mar-06 19:11

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?
