Enhance Perfromance Of An ASP.NET Website
Feb 13, 2009
I'm developing an Auction website using ASP.NET (with VB.NET as code behind) and SQL server. I'm using a timer to refresh the page every second (using AJAX) to get the latest bids and time left to bid. These data come from the DB. I have written 2 Stored Procedures. One will return the Time Left and other will return the Quotes. The reason behind calculating time thru SP is, the time can extend to 10 mins when a participant submits the bid within 2 mins of the closure of event. The problem is the site is very slow and gets hanged in between. Is there any way to change the design to enhance the performance. Any method to avoid frequent round trips to DB? How will i get the latest quotes and remaining time without going to DB?

So here I am asking you out there again for some help. I want each user that logs in to have a different color font for there messages. I believe it would have to go in the recieve messages from server part of the code. Can you please assist with the code and where exactly I would put it. The code below is for the client side there is also a sever side code not provided unless you need it for this project. [code]

I have the following problem: I have a combobox in my application. Sometimes the data inside are too wide to be displayed (see here). Is it possible to use tooltiptext to display the whole data line if the user stands on this line? Or perhaps sending the whole data to a right-click context menu? If so - how?

I had to "Enhance" the small tool tip, as when you press ctrl or alt it fades, so the screen shot only showed it lightly.
I Should mention it works, some of the time. I am Passing strings in this format:

What Im making is like a face book and tagged login from my app
1. I have Combobox with 3 urls in there ( Facebook.com Tagged.com and Bebo.com )
2. I have a Form2 with webbrowser
3. I have a Button when clicked it should open up my form 2 and preview of the website which I selected in my combobox in form1
All I'm trying to do is when I select lets say facebook in my form 1 and click load it should open up my form 2 with facebook website in it.[code]Now when I click my button in form 1 it will load Form2 ( named Explorer1) but my form2 is not showing me facebook or tagged page for some reason

What I want is: To scan a website every 15 mins or so, (craigslist in this case), and email myself any new posts that come up. I know I need to use WebClient, but I never used that before. Another question would be how to only email when a new post is up and not receive the same email every 15 mins.

I have a ASP.NET 2.0 website created in C# that acts as a completely independent site and I am looking to integrate this into an existing ASP.NET 2.0 website created in VB.NET. Unfortunately I just don't know much about the server management side of ASP.NET yet so too much I'm unaware of when it comes to IIS configuration etc. Does anyone have any advice as to how I can go about integrating this? Basically I want to host it in a subdirectory from root so when you hit example.com/myindependantsite/ it will pull up my C# site.
One possible solution I came across mentioned just dropping the project folder into the root directory and setting up that directory as an application virtual directory in IIS? A few other random questions were small things like would my application relative links (~/for-example.aspx) stay relative to my root subdirectory if it's made into an application virtual directory? Just trying to get this running on their site but like I said it's completely independent so want to preserve my websites environment.

I want to create a program to fetch information from a website (that's fine). However, you need to be logged in to get this information. I just want two simple textbox controls that I would type my username and password into and hit submit and the information would be returned to me so I can use it. (I don't want to use a webbrowser control)

So right now, im working on a "log in" app, that logs into facebook.com
I have a
username textbox1
password textbox2
However I dont know how to click the "Login" on facebook.com
I can go to facebook.com/login.php and get that to work...
A few questions, how can i check to make a user is not logged in, and if they are, to press the "logout" option, and clear any cookies from facebook?
Here is what i had so far. just unsure how to check cookies or if someone is logged in.
If InStr(WebBrowser1.DocumentText.ToString(), "Not you? Click here.") > 0 Then
WebBrowser1.Navigate("http://facebook.com/login.php")
End If

I learned I can log into websites using the web browser control provided in VBE 2008 and have done so successfully on several different sites that I use daily at my job. I came across 1 site that uses a lot of pop up windows to navigate through it. The problem is, when I log in using the my web browser control, the pop up (which pulls up the internet explorer) brings up the login screen, I assume because of the site uses sessions. My work around is to attempt to login using the internet explorer. I'm having trouble getting it to work and unable to find answers in the forum (hope I looked in the right place). The app is not doing anything, can someone assist? Here is what I have:

I originally posted this in the ASP.NET forum because I wasn't sure if this would be more of an ASP.NET thing or VB.NET thing. But, since I haven't received any responses, I thought to take my chances here.
I have an app that, among other things, utilizes a bunch of different portable command line apps. My app is downloaded by the user and then they choose to download whichever command line apps they'd like.
The problem, is that this can be anywhere from 70MBs of data to 900MBs. So that the users won't have to download additional files and to eliminate an additional step to use the app, I'd like to run the portable CLIs directly from my website.

I am new to creating websites for people on a money-earning basis.. I created my Dads website for my final year project, and he will pay me eventually but obviously I cant charge him as much as anyone else.I have just been to a trade show where I picked up 1 definite and 2 possible sites to do. The definite one is as follows:They want a site which:Has a catalogue for the customer to view, as well as being able to order products at a retail price.Has an administrative section with order tracking, catalogue management and page view stats.Has other basic pages such as Contact Us, Terms etc (all the usual).Enables customers to post comments about items, as well as manage their accounts (addresses, payment details etc).Is linked up to sage pay or paypal (or something similar).My task is to design this site from scratch and launch it for them. They already have the hosting sorted out, so no need to worry about that in the quote. I am planning on using .net and SQL Server, if this makes any difference.Basically what I would like is to get some quotes for what other people would charge if they were given the task.

I'm getting desperate here trying to find the problem, and I don't know where to start looking for it.
Here are the symptoms:I've noticed, that when a user logs on in the morning, he is then immediately logged off, then when he logs on again, everything is fine and he can work on the site.
Every once in a while, when the user clicks a link, the page takes a lot of time to load, but it never actually loads, and the user is thrown to the login page.Also, after an Exception has occurred in the website, the user is then thrown to the login page. It's as if the exception clears somehow the session.

I have an XML with following structure[code]...
What will be easiest way using vb.net to get description for each SIC from the website? I can not modify this XML file. Do I need to create a collection with SIC code and description manually copied to it and then get description of SIC code in XMl by matching SIC code with collection ? Final collection will be used to populate a repeater with each item/row having SIC code and Industry Name.

Recently we decided to make a web based game that I would like to see on a web page. Prblem is I have no idea how I would get my website to see the program and run it. I'm fairly decent with Vb its self but ASP is completely new to so Im ultra newb. My understanding about using ASP is since its Microsoft based you can't use any tools like WAMP or PHP Admin or anythign I currently have to get ASP programs to run but I could be wrong. I barely know how to setup a webpage so I'm 100% newb on my venture into webpage building but I want to learn more about it.
