Application performance should be good and also easy manageable.


Please suggest me in which way I will build the application either using resource or folder. If there is any other better solution then please share.

Background process and SINGLE_USER


We have a critical heavy loaded task which is running through all user databases of our SQL-Server 2005 (SP3). This operation on each database consists in rebuilding indexes, data changes, updating stored procs....
To be sure that no one is working on a db we are setting each database to SINGLE_USER, when the operation finished with one db, MULTI_USER is set, then the next db and so on. This works well for all normal cases, except sometimes an error occurs in our app:

"This database is already open and can only have one user at a time..."

The application didn't left its connection and nobody else is working on the server! We did some research and found out that a CHECKPOINT background process is swiping the control over our SINGLE_USER connection.

Is there a way to disable or delay the background task? As the Checkpoint writes data from memory to disk, is it possible to manually force a Checkpoint without losing data ?

controllable background process


At Windows startup I need to run a process in background which might take several minutes to complete. When running another application (which I'm developing) and performing a certain task via GUI, I need to pause the background process and access it's data. The big questionmark is: how am I going to create this process and make it accessible to the GUI?

Maybe this info will add further useful info to the case: the GUI should only be able to be started once.

I have no starting point on how to take on this problem, but I do have .NET experience, and I guessed that it's about remoting. Anything to point me in the right direction is appreciated.

ASP.NET Architecture - ASP.NET Worker Process - HTTP Pipleline - Http Modules and Handlers

"ASP.NET is a powerful platform for building Web applications, that provides a tremendous amount of flexibility and power for building just about any kind of Web application. Most people are familiar only with the high level frameworks like WebForms and WebServices which sit at the very top level of the ASP.NET hierarchy. In this article I'll describe the lower level aspects of ASP.NET and explain how requests move from Web Server to the ASP.NET runtime and then through the ASP.NET Http Pipeline to process requests.

Alternating row background for first column of a report


is there a way to make the first column of a report use the an alternating background color? 

I have the background color set for the entire row however it does not work for the first column if the color is set to an expression.  If I just set it to a color i.e. red it works just fine. If I insert a dummy column to the left it works just fine (but the dummy column does not work, presumably because it is first??).

In the file below only the textbox for part number does not show an alternating background.  All others work correctly.

Resources for soup-to-nuts of website development lifecycle



 I'm looking for a website, or book, or some resource that can lead me down the path from website design to implementation/deployment. I know that covers a ton of material, but I am really looking for the bullet points, or high-lights, to make sure that I think of everything. I am mostly fuzzy on security measures and deployment since I haven't been involved in those aspects before.

Background:  I have been a programmer for many years, and with a little over 3 years' experience coding websites in vb.net/asp.net with sql server. Due to recent restructuring/layoffs at our firm, I find myself in the position of lead IT person - I'm feeling a bit underqualified but I feel this is my chance to work hard and step up to it. I'm very good at vb.net, master pages, css, asp.net, sql server. I'm worried that the person who was the lead before was doing a bunch of stuff that I'm not aware of...so I need to start learning more than just the code. I don't need lessons on how to code anything...I need to learn how it all gets put together - the next step up.

thanks for any suggestions!

Why isn't my Views/Home/Home.Master file published when I publish my website?


Hi All,

I spent the better part of today hunting down an elusive error.  I was getting a message saying that it couldn't find the Index view for the Home controller, and it gave a list of locations it searched, e.g., ~/Views/Home/Index.aspx.  This was really confusing as the file definitely existing and was at ~/Views/Home/Index.aspx, the first place in the list of locations it searched for the view!

What I eventually discovered was that there was a file that did not get published when I used Visual Studio's "Publish" feature (this is on the "Build" menu).  That file was Views/Home/Home.master, and (as you can probably guess) is the master file used by Views/Home/Index.aspx.

Once I copied that file into place manually, it started working.  But I am left wondering--why???  Why does this file not get published?  It's a part of my project, I can see it in the solution explorer, and it's obviously a critical file that's necessary for the MVC app to run.  It has the same permissions as every other file in my project.  So why wouldn't it get copied?  And how can I fix it so it does get copied?

Thanks for any suggestions on this!

VS2010 Professional .NET 4.0 Remote Debugging ASP Website Project


Trying to remote debug ASP website from VS2010 Pro to Windows Server 2003 machine.  Specifically, trying to debug a Web Service, but breakpoint says, "The breakpoint will not currently be hit. No symbols have been loaded for this document."  This happens for all compiled code though.  I have read this is due to missing PDB files and the work around is to manually copy them, as noted here.  Problem is, I cannot find any PDB files for my project, except referenced libraries, which I can remote debug.


  • web.config has <compilation debug="true">
  • Debugger is attached to wewp.exe process on remote server
  • Installed VS2010 remote debugger from DVD (as I can remote debug referenced libraries)

This is beyond frustrating.  I migrated my code from VS2008 .Net3.5 to VS2010 .Net4.0 to take advantage of the inherent multithreading framework.  Debugging works when using local host and was stable until deployment to test server.

Thanks in advance,

Citrix server slowing down due to ASP.NET Website



I have created an ASP.NET website using Visual Studio 2008. It is deployed to a local server in my office running Windows Server 2003. This intranet website is accessed by about 200 employees at a given time from 3 different corners of the world.

It runs fine on a local browser. But it is terribly hogging about 25% of the CPU memory when run in a Citrix environment. It runs in the IE 8 with IE 7 compatibility mode.

Many users open two browsers at a time to run different pages of this website.

The webpage has AJAX toolkit controls and lots of CSS defined.

Does anyone have any idea or experience regarding this?
