Having problems installing/setting up SQL Server 2008 Express/R2 for ASP.NET user management on deve

I'm a bit new to installing and configuring, well, just about anything regarding databases, so please bear with me. I'm currently building a couple of ASP.NET MVC 2 sites.  I'm following along with the MVCMusicStore tutorial, and am trying to set up user management using ASP.NET's configuration tool.  The problem is that ASP.NET can't 'see' the database. I have SQL Server 2008 installed on my laptop.  It's the version which is available on the Web Platform Installer (I believe it's Express).  When I try running the aspnet_sqlreg.exe program to set up my user management database, it can't tell that I'm running any version of SQL Server at all.  I get an exception about 'named pipes', and some other things I don't understand at the moment. Obviously, this is all a bit over my head.  Is there an idiot proof guide or tutorial available that describes, step-by-step, how to: 1. Install SQL Server 2008 on a development PC 2. How to configure it to be used by Visual Studio 2010 Professional 3. How to properly upload/modify the db on the production server with what's on the development PC Essentially, all the things that the ASP.NET tutorials gloss over.  Any suggestions, links to documentation, or other nudges in the right direction would be immensely appreciated.

Problems installing the Ajax Toolkit


Hi All

Problems installing Ajax toolkit in MS Visual Studio 2005 Framework 2.050727 SP2

 Followed the instructions on this Site:



Was able to build the TemplateVSI in the solution without any problems but the problem I always encounter is the part where I build the SampleWebsite in the solution explorer.


The build fails with 105 errors


 Error    1          The type or namespace name 'Script' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)    C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\AjaxControlToolkit\ExtenderBase\ExtenderControlBase.cs    16         18         AjaxControlToolkit


ThreadPool problems even after installing fix - Threads are created slowly after they are released



I have a net.tcp service hosted under IIS which is being hit concurrently by 300 clients. After doing a lot of configuration (throttling, maxconnections etc) I show that I have a thread pool problem and requests are not served quickly enough, because thread pool creates new threads every half second. There is no error. My problem is that my clients are not served quickly enough. I configured the thread pool using SetMinThreads but nothing (I also configured SetMaxThreads accordingly). Then I discovered that there is a .NET 3.5 bug and I installed the corresponding fix (http://support.microsoft.com/kb/976898). Now the behaviour I get is the following...

When the 300 clients hit the server, the server opens concurrently 300 threads (I see more than 300 threads for w3wp process in task manager) and clients are served very fast. If after this there are 300 more concurrent clients, they are being served by reusing the previous threads. Excellent!!!

However, if I let the server idle for about 10 seconds, the threads are released! w3wp threads in the task manager drop to around 25. If after this again 300 clients hit the server thread pool starts again to create threads slowly (one every half second)! Why is that?

problems installing ssmse for SS 2008 R2 Express


I have successfully installed SS 2008 R2 Express.  I'm having trouble installing the management console for SQL Server 2008 R2 Express Edition.  I've done this with previous version of SS with no problems.  The documentation that I've found isn't very helpful.

I downloaded the SQLManagementStudio_x86_ENU.exe file from http://www.microsoft.com/downloads/en/details.aspx?FamilyID=08e52ac2-1d62-45f6-9a4a-4b76a8564a2b.  I ran this.   The app that ran doesn't look any different than the installer for SS 2008 R2 Express.   I then chose the option under installation for a new install or adding options to an existing installation.  I clicked this thinkg I needed to add the SSMS to my current installation.  I saw no option to install the SSMS though.  It seemed like it was just going to reinstall SS 2008 R2 Express.  I looked at all of the other options but didn't see a way to do this. 

Can someone please tell me what I need to do to install the management console?  I'm extremely dependent on this and need to get it installed to work with SS.  What am I missing?

Installing and Uninstalling Services

Installing and Uninstalling Services.Unlike most projects you create in Visual Studio .NET, Windows Service projects cannot be run directly from the development environment by pressing F5. This is because the service in the project must be installed before the project can run.

You can quickly install your service application by using a command line utility called InstallUtil.exe.

Top .NET Performance Problems and how to avoid them

Problems with Forms Authentication in DD 4 site


Hello,  I am seeing a strange problem with Forms Authentication in my DD site.   A user logs into and can view/edit/delete data all day, but when they execute a Custom Filter against data (for example , a control DynamicData/Filters/CustomerLastNameSearch.ascx ) then the site auth fails, and redirects to the log in screen.

in web.config I have

     <authentication mode="Forms">
            <forms name=".Star" loginUrl="~/Login.aspx" protection="All" defaultUrl="~/Default.aspx" path="/" timeout="43200" cookieless="UseCookies" />     

Offhand, I am thinking two things : that DynamicData/Filters path requires some special handling for some reason, or the control extension ascx is causing auth to get confused.   Has anyone else experienced this or have any suggestions?  Thanks!

Installing both VS Pro 2008 and VWD2008


I work at an educational institution and in our computing labs we have Visual Studio Professional 2008 installed already. One of our academics has requested me to install Visual Web Developer 2008 Express Edition as they think it's easier for their beginner students to learn, but I've noticed it wants to install it in the same folder as our Visual Studio Professional install.

Can both be installed without the limited VWD interfering with the Professional version?

Problems posting to a package


Hey Y'all

I'm currently creating a program that accesses a mysql package to add data to a few tables.  I'm currently getting an error that says  "

ORA-01403: no data found
ORA-06512: at "JESSE.PKG_WORKPLAN", line 42
ORA-06512: at "JESSE.PKG_WORKPLAN", line 177
ORA-06512: at line 1


These lines are


and 177:add_team_members(V_PROJECT_ID, V_START_DATE, v_FISC_YEAR, V_MEMBERS ,V_NUM_MEMBERS,'add');

Checking these variables in my asp.net page they are all receiving parameters.

Is there a  way to see what the database is actually receiving from the asp.net page?

Or is there another thing to be looking at?


URL Routing and Existing HttpHandler problems


Hello everyone,

I have a problem:

I am currently using 2 features: 

1. HttpHandler

Registering the path="res.aspx" verb="*"

2. URL Routing:

Registering with this pattern: "Company/Edit/{*companyId}","~/CompanyEdit.aspx"

In my CompanyEdit.aspx page, I used httphandler res.aspx to generate some images at client.

  • res.aspx?img=1
  • res.aspx?img=3

Now the problem is here, the page is load success with companyId = "12345", but when the images was loaded at client, it loaded the CompanyEdit.aspx again and show error with wrong id.  

I have debug and find the problem that because when image's urls were generated to client with url=res.aspx?img=1, url=res.aspx?img=3, the asp.net will understand that they are Company/Edit/res.aspx?img=1, Company/Edit/res.aspx?img=3 when it maps with URL Routing pattern.

=> So the CompanyEdit.aspx was load again with wrong id (id now is "res.aspx"). 

So, do you have any ideas to solve this problem, or other design.

Thanks, and best regard

ASP.NET 4 precompilation problems



We used ASP.NET precompilation (first manually, then with VS2008 WDP) with .NET 3.5 almost (see below) successfully.

After we moved to 4.0, the precompilation no longer works properly. The precompilation process itself succeeds, and the website works, but it consumes about twice the CPU it does without any precompilation. We use non-updatable precompilation (so webpages get compiled completely).

Our internal profiling tells us that most of the threads spend their time within variations of the following stack:


  System.Web.dll!System.Web.Compilation.BuildManager.GetVPathBuildResultFromCacheInternal(System.Web.VirtualPath virtualPath, bool ensureIsUpToDate) + 0xa2 bytes 
  System.Web.dll!System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(System.Web.VirtualPath virtualPath, bool noBuild, bool allowCrossApp, bool allowBuildInPrecompile, bool throwIfNotFound, bool ensureIsUpToDate) + 0x5b bytes 
  System.Web.dll!System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(System.Web.HttpContext context, System.Web.VirtualPath virtualPath, bool noBuild, bool allowCrossApp, bool allowBuildInPrecompile, bool throwIfNotFound, bool ensureIsUpToDate) + 0xcb bytes
