AJAX :: Displaying Live Data In Text Box On Webpage?
Mar 10, 2011
I am trying to display the data in text box on web page that is coming from the live control machine, I am able to display these data in console application by using the 'do while' infinite loop and it works fine, now the same thing I want to display the data on the web page, so when data came in it should display on web-page in textbox.
Problem :
I want to write a program by using loop which will display the continuous data for two mins. period on the web page, and after the period it will stop the loop, meanwhile it also display the data on the webpage for the 2 mins. period.
I developed an application form which includes some textboxes for input. When the user click on the button the following tasks has to be done.
1) If page is valid all data should be stored in database
2) A new webform should appear on the same window and the some content of the application form should be displayed in it.
3) When clicking on browser back button it should not post back to previous page.....
I did the first task..and i don't know the code for the remaining tasks. Here is some information
.aspx button control code
[code]....
I opened new webform by using Response.Redirect ("submit.aspx"). Where submit.aspx is the form to be opened after data stored upon the button click in application form.
I have to display images from a video camera in my web page.
What I am already done is, I created a folder in my severer side and continuously check for latest image in that folder.
whenever anew image arrived in that folder I display that image in my web page.
It was working when I am testing the code by dragging images in to that folder one by one.
But, when my application connected to the camera, images was coming in to that folder but my application don't have permission to take those images to display
I am using a generic handler (indicator.ashx) to create a graphic that is overlayed from information from a table (called LIVE) from our SQL database. This is working very well and I am very happy with the results.
However I am having an undesirable issue where the query string that is used for this is also being accessed by another page (called ReceiveLive.aspx) which is populating our LIVE table with data when we don't want this. I have been able to track this issue down to our generic handler that seems to populate this table with data whenever the handler is accessed.
The query string that is used to access our graphic through our generic handler is http://mydomain.com/indicator.ashx?ID=ABC001.
Our other page that writes data to our LIVE database used the query string http://mydomain.com/live.aspx?ID=ABC001 which is normally only accessed by a small piece of software that sits on the users PC and sends the data when necessary.
My question is this: How do I prevent data from being written to our LIVE table via the Live.aspx page everytime a query string is processed by my indicator.ashx is accessed?
I am generating a pdf using iTextSharp. I would like to display it on the webpage and let the user save it from the online pdf viewer. dynamicpdf has a drawtoweb() method, but it is not free to use and I cannot find the same functionality using iTextSharp. How can I display the pdf?
string newFile = "Pdf Document.pdf"; Document doc = new Document(); PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(newFile, FileMode.Create)); doc.AddCreator("Myself"); doc.AddTitle("Sample PDF Document"); doc.Open(); doc.Add(new Paragraph("Hello, World!")); doc.Close();
I have a Label1 (Which displays the userName on a page fetched from the c sharp). Now how do I display this Label1 on a text box(UserId), that's already binded, on the same page?

In my application, in a single page i need to display small images(say some 10, i.e category wise) and if the user selects any one image then it needs to be maximized (like photo album). How I need to do this. Pls any Idea. maximized image will be displayed in the same page or another new page?
I can do the above by placing the relevant .jpg into the VWD project.
However, I would like to be able to to do this without adding the image file to the project.
e.g. In code, get the image from C:/images/NameOfImage.jpg
The reason I am trying to do this is the website will allow the user to upload as many images as they like. Each one's details will be stored in a database, including details of which location they have uploaded the image to. On retrieval, I will get the location of a specific image from the database, and display it on the page.
I needed to display data from a table in this style:
Hotel: hotel1 Destination: United States
From: UK
Hotel: hotel2 Destination: United States
From: UK
Hotel: hotel3 Destination: United States
From: UK
This would all go in a box or table, the bold text is the column names from the table, but id be quite Happy to just have them as text and not display the coloumn headers. whats the best control to display data in this way, ive messing about with different controls but cant get this layout
Live Chat is a very famous tool on websites, and the operators use a special web/windows interface to talk to the clients.What I want to implement is to specify some email accounts, and when the client click's the live chat and starts typing, his/her instant messages are delivered to the available email account. My operators can talk back to them as if they are on their friends list.I don't need to require any login or registration for clients to use this Live Chat.So are there any ideas about how to implement such a thing? Are there any good third-party-modules that already do that?
I have a form where users enter information in a multi-line text box. This could be anything, such as bullets, carriage return line feeds, etc. Think of anything that you might copy and paste into a multi-line text box from Word Pad, or Word. I then store this information into a SQL Server NText field.When I retreive this information, I need to display it as the user entered it into the text box field into a Literal or Label control (or something else if there is a better alternative) to display it. Problem is that when I display this text into the Text property of a Literal control everything is jumbled and all characters (bullets) are lost, no carriage returns, etc. One big mush of stuff. If I display this information in the Text property of Label control, I get the bullet characters, but no carriage returns
I have a program that reads a word document and displays it on the webpage. I am storing all the paragraphs in the word document in an arraylist. Now I want to use arraylist.contains method to search for a particular word and then display the next 8-10 paragraphs after the string match. Here is the code so far.
using System; using System.IO; using Microsoft.Office.Interop.Word;
I have a section of a page with a repeater control on it, taking information from a database, to display the latest information available to users. However it would be preferable to be able to format this information, so that it can have line returns, bold and underline in it. Rather than just single line plain text.
What is the best way to accomplish this? At the moment this is what I have: [Code]....
I have a byteArray which I can only convert into an Image (Drawing.Image) I was wondering how I can display it a webpage. I used memoryStream as I dont want to user to have to download the image. Eventually I will use this to display images in google maps.. I can convert it into a graphic but once again not sure what I will do with it. The Error I have been getting lately is Cannot implicitly convert type 'System.Drawing.Image' to 'System.Web.UI.WebControls.ImageField'
