i have notice that when i try to view the Image used in the Home Page of this site, specifically to the "ASP.NET: Power, Productivity and Speed" Menu part, it has many Images in one file.
Usually when i make such design i have a single Image in a Single file. so how does you people do such re-using of multiple images in one file?
i have an asp.net application, i want to incorporate init the functionality of having the user select from a dropdown list a name, select multiple files (images), upload those images to a physical path on a server, save the image paths to a database on the said server.
If the user fails to select a name from the dropdown list then the user would receive an alert message stating that a name must be selected.
In addition once the files have been successfully saved to the server's physical location, then and only then should the path be uploaded to a table in the database.

I can't use NullImageUrl as the Images are not stored in the database. I can't use the solution found on [URL] as an ImageField does not accept an ID attribute.

I was in need of exporting multiple tables in a DataSet to an Excel file with multiple sheets. I found a very good article in [URL].[URL] was able to successfully export each of my datatables in the dataset to excel worksheets. This solution worked for small number of rows. But when the data got larger I am consistently getting the system.outofmemoryexception. THis is because the code is using up the memory when creating excel.
Does anyone have another option to do the above?

View 2 RepliesI'm using a slightly modified version of Valum's upload [github link], I've modified it to upload to a database but haven't modified the javascript that it is using to get the file into the Request as an InputStream. The following line of code is failing in IE 8 but is confirmed to work in Chrome. using (Image imgInput = Image.FromStream(Request.InputStream)) The error received is "Parameter not valid". It appears to be having an issue with the Input Stream being used but it exists/has data (not sure how to validate if the data is good or not).

I need displaying my image file stored from my database into the image control. I've had read some articles and watch video tutorial which there were perfectly working and I followed it but I wasn't able to make it work. The image control just displayed blank. I used Generic Handler to retrieve the image file from my database based on the articles and tutorials I've got. here are my codes below:
Generic Handler:
Code:
<%@ WebHandler Language="C#" Class="ShowImage" %>
using System;
using System.Configuration;
using System.Drawing;
using System.Drawing.Imaging;
[Code] ....
Asp.Net Code for the Image control:
HTML Code:
<asp:Image ID="Image1" runat="server" ImageUrl='<%# "ShowImage.ashx?ID=" + Eval("ID") %>' Height="128px" />
I want to make a textbox with a specific style, within this style a set of images as background parts, how can i attach these images to the custom control as whenever i take the .dll file and add it to the toolbar the images do not appear. So i tried to make them as resource files and their property as embedded in .resx file, so how to make the css style background image url to be linked to any of those image.
