I am new to cloud computing, so please bear with me here. I have an existing ASP.NET application with SQL Server 2008 hosted on a Virtual Private Server. Here's what it briefly does:The front end accepts user's requests and adds them to a DB tableA Windows Service running in the background picks up the request, processes it and sets a flag.The Windows Services also creates a file for the user to download
View 1 RepliesI am currently building a web application that will involve many servers to get it to run efficiently. I am trying to test this web site at home and I have a few computers running the website. To connect to the website I would type this into the address bar http://192.168.0.200:8080 or I would typehttp://192.168.0.201:8080. However when I transfer my site from one computer to another the web browser can no longer read the cookies. I would like to set up a home DNS server and have the computers in my house access the site like this w1.MySite.com and w2.MySite.com instead of http://192.168.0.200:8080 or I would type http://192.168.0.201:8080 so I can test if my cookies are working accross subdomains. how to set up a local DNS server so I can do this?

I am having a simple Azure cloud app(WebRole=ASP.Net MVC) which draws charts using ASP.Net Charting control. Chart RenderType = ImageMap Chart ImageLocation = "/Images/Chart_#SEQ(1000,1)" Number of app instances deployed on Windows Azure = 5 App contains a button which draws charts as per users parameters. When user clicks on this button, MVC action is called which provides necessary ViewData for drawing chart and returns a partial view which after getting rendered sends ImageMap and Image location to client.
When I try to draw charts from IE8 I always get the charts as per my parameters but when I simulataneously try to draw charts on FireFox sometimes I get wrong charts(wrong images). Is is due to roundrobin used - #SEQ(1000,1) or due to mutiple instances of my cloud app?
I have an ASP .net Web Application already deployed on my local machine (virtual directory/IIS are configured). I used the Publish tool from Visual Studio. Now I want to move it to our Webserver (I have the IP adress and the appropriate credentials).
EDIT By the way, I'm asking because I don't know if there is a specific way to do this? I can do it manually by moving the files to the remote computer and configure IIS approriately.
On Button Click how to move the mousecursor position in web application???
In case of windows application on button_click i have written the following code:
Point p = new Point();
p.X = 41;
p.Y = 400;
Cursor.Position = p;
This works fine & cursors position also change.
but how to do that on aspx page or in web application?
In my case also on button click i have to move the cursors position.
I am rather new to asp.net but I have built a couple of apps that do not require users to login. am having some problems moving my secure .net application from my laptop to a production server, however, and I am hoping someone can help me. On my laptop my application's user authentication functions as it should, but when I move my application to a webserver I get an assortment of errors. Forgive me if these questions are a little basic. My first question is this. In a production environment do I move the ASPNETDB.MDF file in the App_Data folder to my SQL server? Is it OK to rename it to something more descriptive?
View 4 RepliesI need to move all requests from one domain to another. I want to change part of URL, like subdomain.olddomain/url -> subdomain.newdomain/url.
I was sure that this is piece of cake and wrote Application_Begin request as:
void Application_BeginRequest(object sender, EventArgs e)
{
string url = Request.Url.ToString().ToLower();
string from = ConfigurationSettings.AppSettings["from"];
if (url.IndexOf(from) >= 0)
{
url = url.Replace(from, ConfigurationSettings.AppSettings["to"]);
Response.Redirect(url);
}
else
{
if (url.IndexOf("error.aspx") < 0)
{
Response.Redirect("Error.aspx?url=" + Server.UrlEncode(url));
}
}
}
So far, I forget, that BeginRequest started only when file physically exist. how I can make such redirect in asp.net without creating hundreds of old pages?

We have an already existing project on IIS and we want to move to Apache (windows) with mod_aspdotnet. What things could not work? If we use 3rd party DLLs?

View 2 RepliesI am planning to build a news publication website that should be automatically scalable when traffic is increasing. I have good experience in developing web applications using ASP.NET and PHP. To move forward on selection of specific technology here are some questions for which I need some clarifications.
My primary intention is to reduce the hosting charges. If we choose LAMP this will cost lower than ASP.NET on Windows. As my intention is to host web application on cloud service, will this make any difference? Means, for dedicated servers we need to pay extra cost for Windows O/S if you compare it with Linux. If we go for cloud servers, will they charge anything for O/S for each instance or will they just charge on computation hours irrespective of Operating System?
Do we have complete control (like dedicated server) on cloud instance to install any other softwares?
Do we need to host web server and and database server on multiple instances when traffic is increasing or will a big size instance can handle huge traffic?
In my C# asp.net 3.5 application I am using RSS Feed to get current updates of my website. Its working fine and when we subscribe the feed also its updating the data as needed.

But When I say Subscribe to this feed Its giving diagnose error page saying Normailization error occured and can not display the page. Let me know how to work with RSS feed in cloud environment.

I was not able to do unit testing for our existing web site project. I converted the web site project to a web application project. I did some unit testing and changes on the converted web application project. However, my co-worker was doing UI testing on the web site project. We need put UI testing and unit testing to the web application project. Is it possible to move the UI testing code that my co-worker did to the web application project I am working? If so, how do you do it?

Rackspace will not install the MSChart.exe package on the Rackspace Cloud Sites servers.
I installed VS2010. Then The Azure toolkit. I created a new solution, with one webrole in it. I added 'HelloAzure' to the default.aspx, and then pressed f5 to run it.
It runs! I see my text 'HelloAzure' in IE8. Yeah!
Now, when I close IE8, it seems that VS2010 simply hangs, is frozen. It accepts no input from mouse/keyb. Nothing moves ... you know ... it hangs.
Taskmanager is required to get out if this state.
A picture is supposed to be worth a 1000 words, so let's see if that can shorten this post up a bit... Essentially, I'm looking into "how" to code a solution that runs on the web server within the cloud that will send a print command to a printer within office 1 (label printer).
The print job is really part of work flow within the ASP.NET web application and I would like to keep all of the code within a single application if possible. How can I go about doing this?
Due to security, I should avoid creating a new application within Office 1 that pulls data from the "cloud" and have the "cloud" be used to push the command downward. I'm really looking at this from a code standpoint within the ASP.NET app and also potentially transcending into more of a serverfault/superuser question on the printer. I'll save that for a future question there though.
see this [URL]The double headed white arrows is my illustration of how I did this I have a bunch of labels from the left, then I need a measured space to the right hand side. All I could do was this
<a href="http://www.twitter.com/xxxxxxxxx"><img src="http://twitter-badges.s3.amazonaws.com/twitter-b.png" style="border:solid 0px white;" alt="Follow xxxxxxx on Twitter"/></a>
Is there a better way to have the twitter image parked always on the right hand side after menu labels.??
so if I have a new project.. and throw a list view on there I can make the position absolute and move it all over..
if I try to add a new listview to an existing project it throws it to the left edge all the time..I have other controls already there and I can move them... just not a new list view...
if I add a new label I can move it.. just not a new listview.. is there something I'm missing ?
I have my check box set in options to be able to move controls so I know that's not it..
