based on a recent article on MySpace blaming the microsoft stack not being able to easily scale here.Is this true? Is scaling an app built on the microsoft stack (asp.net mvc here) nearly impossible? does php/LAMP really scale better than microsoft?
View 1 RepliesLet's say I asked Microsoft to describe the perfect, modern, Microsoft-based technology stack to power a standard e-commerce web site, which perhaps has a simple 2-tier web/database architecture. What would it be like? Yes, I'm just looking for a list of product / technology names.
For example, in the J2EE world, I might describe a stack that includes:
J2EE 6 standard
JavaServer Faces
Glassfish 3
MySQL 5.1.x
I'm guessing this stack includes some combination of .NET, SQL Server, ASP.NET, IIS, etc. but I am not familiar with this world. Looking for ideas on the equivalent in Microsoft-land.
I'm looking for suggestions for the following issue, and I realize there is really not going to be a perfect answer to my question:I have a UI built in WinForms.NET (v4.0 framework) with WCF back-end and EF4 model objects, that I am looking to port to the web. UI is not huge and is not super complex and is structured well. But it is not a super simple system either. I am looking to pick a technology stack for the web-frontend that will target desktop & partially mobile platforms, provide a good development platform to build on, and facilitate code reuse across UI and back-end tiers...

I maintain a web application (ASP.NET/IIS7/SQL2K8/Win2K8) that needs to access documents, actually hundreds of thousands of documents, and growing. Currently, they are all on a Windows 2K8 Server fileshare, being accessed by UNC path (SMB). The files are in a single flat directory and I'm trying to plan how to best improve this solution. I don't want to use the SQL Filestream attribute as it would be significant effort to migrate it all into that, and would really lock in to SQL Server. I also need to find a way to replicate the data for disaster recovery, so perhaps a solution can help with that too. Options could be: Segment files into multiple directories? application would add metadata for which directory it's on (or segment by other means) Segment files into separate servers? (virtualize)Backup becomes more complicated. Application would add metadata for which server it's on
NAS Storage
SAN Storage
Put a service (WCF) in front of the files and have the app talk to the service bonus of being reusable across many applications Assuming I'm going to store on filesystem and not in database (I've read those disccusions here), which would be a more scalable solution?
I'm thinking of using ASP.NET and MySQL together on a large project. Does anyone have any experience in using these two on a large scale and are there any aspects I should be wary of? If there is a chance that there could be compatibility issues, then I may be prepared to purchase an MSSQL license, but I'd rather go the free route right now. In theory it's possible, but how easy is it to transfer a MySQL database to and MSSQL database in the future?(I'll make this a CW if requested).
View 2 RepliesOkay in my WebApplication i have a webform showing some pictures.The pictures - or better - the picturepath i get from a database.
With this paths i am loding the pictures into my webform.
Now i want to render a scale into these pictures. For example lets say 1px = 1cm.It should look something like in this sample picture:
Is it possible to realize somethin like that and how?!
I tryied to google something but i could not find anything!
I am using abcPdf to convert an HTML report into a pdf file. The pdf has to be a single landscape A4 page.Do you know if there is any way to tell abcPdf to scale the HTML page to fit on a single page in the pdf? I tried using the Magnify() method, and it scales the content but still breaks it into pages, even though it would fit on one page. I've been scratching my head on this for a while now

View 1 RepliesI have to do the following.
There is a database (SQL Server) with locations (longitude and latitude values). I need to plot the route on the map (Google or otherwise) based on those locations extracted from database. Plotting lines and map are on ASP.NET webpage.
What would be the most and cost-effective way to accomplish the task above?
I am working on a site where I will need to be able to track ad impressions. My environment is ASP.Net with IIS using a SQL Server DMBS and potentially Memcached so that there are not as many trips to the database. I must also think about scalability as I am hoping that this application becoming a global phenom (keeping my fingers crossed and working my ass off)! So here is the situation:
My Customers will pay X amount for Y Ad impressions These ad impressions (right now, only text ads) will then be shown on a specific page.The page is served from Memcached, lessening the trips to the DB When the ad is shown, there needs to be a "+1" tick added to the impression count for the database
So the dilemma is this: I need to be able to add that "+1" tick mark to each ad impression counter BUT I cannot run that SQL statement every time that ad is loaded. I need to somehow store that "+1" impression count in the session (or elsewhere) and then run a batch every X minutes, hours, or day.
Please keep in mind that scalability is a huge factor here.
On my X Axis, I have months. The chart shows up to 11 points, i.e. Jan - Nov of the same year, but when I add 12 points (Jan - Dec), it will do an auto label thing and change the interval for every 4 months.
How can I change the graph so that it shows 12 months before it does the auto labels?

And the stack trace is as follows[Code]....I am not able to get what is the problem here?
we are getting a stack overflow in production ~ 2-4 times / dayWe cannot reproduce this is in dev environment, nad given this is a web app with probably ~100 concurrent users at any one time, I'm struggling to work out how best to track this down.Is there anyway to get any more info from event viewer - happy to install some form of listener tool - even if i can just get teh thread identity (set to the current user) that'll help - although the dll + class / function woudl be great!

View 7 RepliesI'm using ASP.NET for a search app web site.My search retrieves exactly one result per fetch. Once the search is complete and the user selects "Update", a new result is fetched and the old result is written to the ViewState as a generic List. The new result replaces the old one.I am trying to get the page to update (via partial post-back), so that the old result drops down the screen and the new result sits on top of it. Much like the concept of a stack.

How can i solve this problem.
How would you implement a user message stack in ASP.Net MVC? (you set messages for the user in any place inside your app. and they are shown as hints of your app to the user anywhere inside the app)

View 2 RepliesI have a remoting-type set up within my application where I avoid TargetInvocationExceptions and grab the inner exception. I invoke the internal PrepForRemoting method on the Exception class to preserve the stack trace from the invoked method.
This appears to construct the stack trace property correctly:

Calling Server.GetLastError(); on Application_Error in Global.asax shows the correct stack trace. Where is the yellow screen stack trace coming from?

at System.Web.UI.WebControls.Repeater.CreateControlHierarchy(Boolean useDataSource)
at System.Web.UI.WebControls.Repeater.OnDataBinding(EventArgs e)
at _Default.up1_Load()

is it happening in the Repeater1_ItemDataBound sub routine, or in the Timer1_Tick sub routine? Is the last thing that happened before the error occured at the top or bottom of the trace?
