Hello friends
in my windows form , there is a listbox which gets filled on the form load event.
on the button click event, the item selected in the listbox is deleted from the database and message box appears telling that the this item has been removed from the database
the problem is that I want that after the messagebox is closed, the list box should be refreshed now holding the items that are now currently in the databse and the item I have just deleted should not appear in the listbox.
How will I achieve this?
Looking forward for ur kind suggestions on the problem.
Thanks
Sadaf

Clear the contents of the listbox and fill it again. You can also just remove the item you have just deleted but in that case listbox won't contain any items that have been added after your programs startup and will contain items that have been deleted by other users.

as for my point of view first you should look into the mechanism of how to take a screen shot on your local machine. If you're successful in that you can then think of using Sockets and all that stuff to get the screen shot of a machine over LAN.

JPEGs are never indexed, so you really can't. A jpeg is lossy and no matter what colors you start with, it will go to 24 bit and the lossy compression will add colors.
If you were to save back out as a tiff, then I guess you could find the colors you want my looking through the pallette. I never use 256 color tho, nor do many other people, it's a shame you need to.

You can't do that without setting up a merchant account with a bank, unless you use paypal or something.

Look here[^].
You seem to be asking a lot of entry level questions, do you own a C# book / I hope no-one is paying for you to write code at this time ?
1 does not create an object, it creates space for an object. obj remains null in example 1.
Please buy a book.

I am trying to watermark an image with Embossed text & with opacity of color. Here is code which i am using.
Problem Description: Watermark & embossed look works K , but i want same color of text (little darker), as the source image have, any idea how to use color pellete of indexed image to draw text with its colors or any other solution, any tip will be highly appreciated.
Image watermarkImage = null;
using (watermarkImage = Image.FromFile(@"C:\NYDN 2008-02-18E\ENV13614\ENV13614 002P.tif"))
{
System.Drawing.Font myFont = new Font("Arial", 58, FontStyle.Bold);
System.Drawing.Color myWatermarkColor = Color.FromArgb(120, 120, 120);
Bitmap btmImage = new Bitmap(watermarkImage.Width, watermarkImage.Height);
// Get a graphics context
Graphics g = Graphics.FromImage(btmImage);
g.DrawImage(watermarkImage, new Rectangle(0, 0, btmImage.Width, btmImage.Height), 0, 0, watermarkImage.Width, watermarkImage.Height, GraphicsUnit.Pixel);
watermarkImage = btmImage;
// Create a solid brush to write the watermark text on the image
Brush blackBursh = new SolidBrush(Color.FromArgb(58, Color.Gray));
Brush whiteBursh=new SolidBrush(Color.FromArgb(58,Color.Black));
//Brush shadowBursh = new SolidBrush(Color.FromArgb(45, Color.Black));
int numofLayers = (int)(watermarkImage.Height / 100);
int lineHeight = 0;
for (int i = 0; i < numofLayers; i++)
{
g.DrawString("© Property of the New York Daily News.© Property of the New York Daily News.© Property of the New York Daily News..© Property of the New York Daily News.", myFont, blackBursh, 1, lineHeight+1);
g.DrawString("© Property of the New York Daily News.© Property of the New York Daily News.© Property of the New York Daily News..© Property of the New York Daily News.", myFont, whiteBursh, 0, lineHeight);
lineHeight += 100;
}
watermarkImage.Save(@"C:\temp.jpg");

Hi,
I have a requirement to remove some data from the Excel sheet which is located on a remote computer. Afer removing the data, the Excel should be saved on same name only. The problem here is I'm not able to delete the data. It is giving me the error message that "could not access the remote computer....". I have mapped the network drive correctly which gives the access. Please any body help me where I'm going wrong. Do I need to do anything more? Thanks.

How can i generate a automatic number each time in c#

I recommend you read this[^], and the guide on asking questions. I *think* your question is easily answered by google, but it's hard to know for sure, because I'm not entirely sure what you're asking. You want to generate what sort of number ? How does it change ? How long does the sequence maintain state ? What for ?
