SQL Express 2005 Caching?
Oct 27, 2007
Hi..
I have a large database which powers an old ASP website, until I have time to migrate the old ASP pages over to .NET I was wondering if I am able to use any caching settings in SQL Express 2005??
What I mean is, can I long in to SQL using the management interface - And set up some sort of caching for the databases I have in there? I wanted to cache the database for say 10 seconds.. As I get alot of hits on the site and this would help speed things up / save resources.
Any tips / help appreciated...
Thanks
Also I don't want to get into hacking around with the ASP code... As I am in the middle of migrating the pages, hence I was hoping this would be the quickest way if it was possible

I am building a web app using VS2005 and SQL 2005 I would like to use the Caching Application Block to cache objects from my BLL. I was wondering if there is a way of utilizing the build in SQLDependency in SQL 2005 with the Caching Application Block??? Does anybody have tried this, are there any samples on the web???
Thanks,

Do anybody know if Analysis Services 2005 allows cashing (storing) calculated members ?
There is a cube in Analysis Services 2000 with a calculated member based on some running sums. The performance of MDXs is too slow because running summs are being recalculated for each member of time dimension on each call.
I think that caching calculated members might help me and hope that this feature exists in Analysis Services 2005 .
Thanks!

I've heard that the Standard version supports the use of CommandNotification and that the Express version does not. What about the Workgroup edition?
The reason I'm asking is because there is a substantial monthly difference in cost between the two versions if I were to have my site hosted. I've been developing with MS SQL 2005 Express so obviously I have not tested this caching feature. Are command notifications reliable? On paper, it sounds impressive and extremely efficient especially if a site is to have heavy traffic and you can't afford the overhead of heavy database processing that is useless if the data is unchanged.
Does the Workgroup edition support automatic change notifications? Have automatic notifications been proven reliable and vastly more efficient than crude polling methods?
Thanks in advance.

Hi,
I'm trying to learn some VB programming with the VB 2005 Express Absolute Beginner Series video tutorials (which I think is great) and have come across a problem that I can't solve.
When I follow the instructions in Lesson 9 (Databinding Data to User Interface Controls) my application will display the data from the database correctly and I can edit it (and as long as the debugger is running the data remains changed). However, the changes won't propagate back to the database. I don't get any error messages but after I edit the data, save (with the save button on the BindingNavigator toolbar), and end debugging the data in my database remains unchanged. When I use a MessageBox to show how many rows where edited/updated in the
Me.myTableTableAdapter.Update(Me.myDatabaseDataSet.myTable)
I get the correct number back. I'm sure the problem is not due to coding errors since I've also tried running the accompanying Lesson 9 project file that can be downloaded from MSDN and the problem persists.
I'm using Windows XP SP2, SQL Server 2005 Express Edition and VB 2005 Express Edition. I've tried installing SQL Server 2005 Express with a number of different settings, including default settings, but it doesn't make any difference.
Would greatly appreciate any feedback on this as I'm keen to resolve this problem so I can get on with the next tutorial lesson.
Thanks,
Ieyasu

This problem only occurs after deployment, not when debugging. In the table I am having a problem with I have an ID field designated as the primary key with the identity increment set to 1 and the identity seed set to 1. There is no data in the table when deployed. I can add records to the datagridview control but when I try updating the dataset I get this error indicating that the ID field already has a value of 1 present. If I close the application and re-start it, the exception no longer occurrs when I update the dataset. I am including the code to update the tables incase something is wrong there. Any suggestions?
Private Sub UpdateMemberTable()
Me.Validate()
Me.TblMembersBindingSource.EndEdit()
Me.TblMembersTableAdapter.Update(Me.ChurchFamilyDataSet.tblMembers)
Me.TblMemberDependentsBindingSource.EndEdit()
Me.TblMemberDependentsTableAdapter.Update(Me.ChurchFamilyDataSet.tblMemberDependents)
Me.TblMemberContributionsBindingSource.EndEdit()
Me.TblMemberContributionsTableAdapter.Update(Me.ChurchFamilyDataSet.tblMemberContributions)
End Sub

When I installed VS 2005, it installed the default version of SQL Server 2005 Express that ships with Visual Studio 2005 installer media.
How can apply SQL Server 2005 Express SP1 to update this existing instance?
Currently, if I run this query:
SELECT @@version
I get the following:
Microsoft SQL Server 2005 - 9.00.1399.06 (Intel X86) Oct 14 2005 00:33:37 Copyright (c) 1988-2005 Microsoft Corporation Express Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
After applying SP1, I should get 9.00.2047.00.
Should I just go to this link and download & install the SQL Server 2005 Express Edition SP1:
http://msdn.microsoft.com/vstudio/express/sql/download/
Thank you,
Bashman

This is what I have done.
1. Installed VB.NET IDE 2008 and SQL Server Compact 2005. IDE requires upgrade of database to 3.0 version which I allowed it to do. After the database was upgraded, I did an amount of coding work in the IDE and then tried to go back to do more database work in SQL. However the database then could not be opened in SQL Server Compact 2005. An error said that because it had been upgraded, it could not be read. It was requiring me to run 'upgrade.exe'. I had no idea what this meant and could find no upgrade available online.
2. Removed VB.NET IDE 2008 and installed 2005 instead. However, the file extension on the SQL Server Compact database is .sdf, but the IDE is requiring a .mdf extension. I have tried everything I can think of to get it to save or to have the desired extension, but I cannot.
Questions:
1. Do SQL Express 2005 and VB Studio Express 2008 work together?
2. If so, how?
It seems as though application each requires a different version of the database. If the database is usable in one, it is not usable in another.
Thanks for the help.

I have a 2005 Express DB I wish to attach to using the 2005 Mgt Studio Client (Not the express version, but the full blown 2005 Mgt Studio Client from the SQL 2005 Standard Edition Install disk). Can this be done, or can I only use the 2005 Mgt Studio Express Edition Client?
Thanks in advance.

Hi all,Just wondering if SQL 2005 express edition can be connected remotely. I've set up SQL 2005 Express on a separate machine and am having trouble connecting to it from VWD when creating the websites. Currently I've set up ASP.NET 2.0 Framework on the remote machine with IIS6 using Windows Server 2003 Web Edition. And I am directly editing the website remotely on the server machine from my PC. Could someone please help me in setting up a remote connection from VWD to the SQL Server?I've enabled TCP/IP setting in the SQL Configuration Manager but still getting errors. Could this be an issue with Express Edition? Because if it is I also have a copy of SQL Server 2005 to install. Any direction to resolve in this issue would be greatly appreciated.PS. I'm new to this so pls bear with me. Thanks.

This is a question about the movie collection starter So here it is:
I am running Vista RC1 (Build 5600) and vb express 2005
I downloaded and install SQL Server Express 2005 Edition SP2 - Since SQL Server Express 2005 Edition SP1 does not work with Vista
But when I try to run the collection app or if I try to download and install the Amazon version I get the following error message:
There was a problem loading data: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be cause by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I need any advice you can give me to solve this problem, how to change the default settings, because I do not know where to start.
Thanks

Hi,
I want to make a component library in Visual Basic.NET and connect to a remote Sql Server. When I create a new DataSet with the wizard, I can only connect to a .mdf file, but not to a Sql Server. With Visual Web Developer I can connect to a Sql server. What is the difference between these enviroments ? How can I do the same with Visual Basic.NET ?
Thanks in advance.

I've downloaded and installed both of these (VWD installs both) and have been trying to run through the walkthrough of setting up a web application which supports membership. However, no matter what I do I invariably get errors like the following:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
I'm concerned why VWD and VSQL express versions don't run correctly out of the box (so to speak). I'm not an expert on configuring these services -- but that's the point of offering these tools to hobbyists: So we can learn about how to make some of these great applications using MS tools.
My configuration::
Windows XP SP2 -- clean machine as of about a month ago, never had any dev tools, web servers, or the like on it.
IIS is installed and the service says its running
VSQL and VWD express versions installed (no errors on installation)
SQL server service indicates it is running
.Net 2.0 framework installed (no errors on installation)
Note: I've tried installing on two separate machines. Obviously I'm missing something fundamental.
Would someone please help me go through the million things I [apparently] need to do to configure all these tools so I can get on to actually coding up my first web application? If this is documented somewhere, all I can say is I tried to find it but it certainly wasn't obvious.

Hello..
I've installed Visual Basic 2005 express edition & tried to connect to SQL Server 2005 express edition. I noticed that VB2005 Express Edition doesn't have any OLEDB provider for SQL Server. The only OLEDB Provider is for M.Access. Is this correct? if so, what should i do if i want to connect SQL Server 2005 express edition with VB2005 express edition by using OLEDB connection type?
I really appreciate any respond from you guys.. Thank's and waiting for the good news..

Hi all,
For the first time, I want to set up the configuration of my SQL Server Management Studio Express (SSMSE) to allow me in doing the non-User-Instance/ADO.NET 2.0 programming from my VB 2005 Express. The SSMSE and VB 2005 Express are in my Windows XP Pro PC that is part of our NT 4 LAN System in our office. I read the article "How to configure SQL Server 2005 to allow remotre connections" in http://support.microsoft.com/kb/914277/ about (i) "Enable remote connections for SQL Server 2005 Express", (ii) Enable the SQL Server Browser service", (iii) Create exception in Windows Firewall, and (iv) Create an exception for the SQL Server Browser service in Windows Firewall. I entered the SQL Server Surface Area Configuration and I could not decide what options I should take for doing the non-User-Instance/ADO.NET 2.0 programming from my VB 2005 Express. I have the following questions on the page of "Minimize SQL Server 2005 Surface Area":
(1) I saw "Configure Surface Area for localhost [change computer]". I clicked on [change computer] and I saw the
following: Select Computer
The Surface Area Configuration of this surface area of this computer or a remote computer.
Specify a computer to configure: O Local computer
O Remote computer
Should I choose the "Local computer" or the "Remote computer" option?
(2) Below the "Configure Surface Area for localhost [change computer]",
I clicked on "Surface Area Configuration for Service and Connections", Select a component and then configure its services and connections: |-| SQLEXPRESS
|-| Database Engine
Service
I picked => Remote Connection
On the right-hand side, there are: O Local connections only
O Local and remorte connections
O Using TCP/IP
O Using named pipes only
O Using both TCP/IP and named pipes
Should I choose O Local and remorte connections and O Using named pipes only?
Please help and tell me what options I should choose in (1) and (2).
Thanks in advance,
Scott Chang

Then I went to microsoft website: http://msdn.microsoft.com/vstudio/express/sql/register/default.aspx and downloaded and installed the so called Microsoft SQL Server 2005 Express Edition and I got the messages Error that you read below. Then I Uninstalled Microsoft SQL Server 2005 Express Edition and went again to msdn website and downloaded Microsoft SQL Server 2005 Express Edition Advanced Services SP1 and installed it. I got again the same message as below.
MESSAGE:
1. First comes a window with the title: €œsetup.exe €“ Unable to Locate Component€?
And it displays a message:

Everything was working fine. I have been able to connect using windows authentication. Then, I went into the ODBC manager to add a data source and it failed to connect so I went back into the Server management studio to modify users. After doing this I now get an error when I try to conenct the management studio to the SQL server.
I wasn't modifying the login for my windows account that I normally use, I was modifying a different one, however I now get the message "An error has occured while establishing a connection to the SQL server. This kind of problem can ocure because the default behavior of the server does not support all connection methods" blah blah.
Does anyone know how I can attach to the server? Or, do I need to somehow remove the server and create a new one? How would I do that?
Thanks in advance for any input.

I get an error dialog when I try to create a new SQL database, both via the Add New Item dialog and the property wizard of a new SqlDataSource control. The error is:
Local Database File:
User does not have permission to perform this action.
I've searched for help with this.
I ensured the App_Data folder exists and I added the local ASP.NET account to the group that have R/W access to it (although the RO flag is in an unchangeable tri-state on the folder).
The SQL Server Express error log is clean and indicates full functionality.
Everything is running locally.
No VWD installation errors.
Any ideas?
Thank you!

Hi. I'm trying to get full-text search working on my SQL 2005 Express with Advanced Services and am having problems. I thought that I installed it correctly, and when I look in the services running, I see it SQL Server Fulltext Search(MSSQLSERVER). Also note that I have SQL Server 2005 Standard installed on this same laptop. I don't know if that Full text Search applies to the Standard, Express or both.
What I do see is that if I connect to the database engine named <mylaptop>, I can see the version is 9.0.1399 and I can see the check box to enable full-text indexing in a particular databases properties. When I run SELECT FULLTEXTSERVICEPROPERTY('IsFullTextInstalled'), I get a 1.
However, when I connect to the engine name <mylaptop>SQLExpress, I se the version is 9.0.3042, and I don't see the same check-box to enable full-text indexing. When I run SELECT FULLTEXTSERVICEPROPERTY('IsFullTextInstalled'), I get a 0.
I've never tried this before so I know I'm probably missing something basic. But, I have searched quite a bit and not found my answer. So, I'm looking to you for help.
Thanks in advance.
John.

Hi All,I have an application that reads data from a very slow database link(like 10 seconds per call) though what I am looking for would be ofgeneric use for anyone who has long-running queries that arefrequently repeated.I would like to be able to cache the results of a query so that I donot have to re-execute that query if it is reissued. Ideally Ibelieve that this could be implemented by hiding the query inside aUDF and exposing the UDF through a view. The UDF could then "Checkthe cache" and only run the slow query if there wasn't a match (or ifthe match was too old). From what I understand the best way to dothis would be for the cache to be an extended stored procedure.Has anyone done or seen this? Has someone written a copy that Icould purchase? Does anyone care to offer their opinnion of how or ifthis could work?Thanks in Advance,Steven

Hi all,
In my office computer network system (LAN), my Windows XP Pro PC has SQL Server Express and VB 2005 Express installed and I was granted to have the Administrator priviledge to access SQL Server Express. I tried to create a SQLCLR project in my terminal PC.
1) I tried to set up a remote connection to SQL Server Express in the following way: SQL Server EXpress => SQL Server Surface Area Configuration. In the Surface Area Configuration for Service and Connection - local, I clicked on Remote Connection of Database Engine, SQLEXPRESS and I had a "dot" on "Local and remote connections" and "Using TCP/IP only". Then I clicked on "Apply" and "OK" buttons. Then I went to restart my database engine in SQL Server Management. When I went to check SQL Server 2005 Surface Area Configuration, I saw the arrow is pointing to "Service", not to "Remote Connections"!!!??? Is it right/normal? Please comment on this matter and tell me how I can have "Remote Connecton" on after I selected it.
2) After I restarted the database engine (I guess!!), I executed the following project code (copied from a book) in my VB 2005 Express:
//////////////--Form9.vb---/////////////////
mports System.Data.SqlClient
Imports System.Data
Public Class Form9
Dim cnn1 As New SqlConnection
Private Sub Form5_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'Compute top-level project folder and use it as a prefix for
'the primary data file
Dim int1 As Integer = InStr(My.Application.Info.DirectoryPath, "bin")
Dim strPath As String = Microsoft.VisualBasic.Left(My.Application.Info.DirectoryPath, int1 - 1)
Dim pdbfph As String = strPath & "northwnd.mdf"
Dim cst As String = "Data Source=.sqlexpress;" & _
"Integrated Security=SSPI;" & _
"AttachDBFileName=" & pdbfph
cnn1.ConnectionString = cst
End Sub

I got the following error messages:
SecurityException was unhandled
Request for the permission of type 'System. Security. Permissions.FileIOPermission,mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'failed that is pointing to the code statement "Dim int1 As Integer = InStr (My.Application.Info.DirectoryPath, "bin")."
Troubleshooting tips:
Store application data in isolated storage.
When deploying an Office solution, check to make sure you have fulfilled all necessary requirments.
Use a certificate to obtain the required permission(s).
If an assembly implementing the custom security references other assemblies, add the referenced assemblies to the full trust assembly list.
Get general help for the exception.
I am a new Microsoft VS.NET Express user to do the SQL Server 2005 Express and VB 2005 Express programming by using the example of a tutorial book. Please help and tell me what is wrong in my SQLCLR sep-up and project coding and how to correct the problems.
Many Thanks in advance,

Downloading and installing VS 2008 Express also created a Miscrosoft SQL Server folder. How do I install the SQL Server 2005 Express?The following is what I found from the HELP menu bar of the VS 2008 Express. Where can I find the sqlexpr.exe?
TIA,Jeffrey
To install SQL Server Express To begin installation, double-click sqlexpr.exe. Note: SQL Server Express is available as a self-extracting executable file (sqlexpr.exe) from both the Visual Studio 2005 CD and the SQL Server Express Web site. SQLEXPR.EXE installs on x86-based computers and to the 32-bit subsystem (WOW64). For more information, see Hardware and Software Requirements (SQL Server Express)
