hi all
iam trying to build an asp.net webpart site, i donot want to use SQL Server Express for it, rathar than that i planned to use an sql server 2000 database , so far after doing this my pages is getting me this errorAn 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)
where i surprise because i tell it in web.config to use my profile rathar than this default one, can any one tell me the secret behind that
Regards,
I just installed a fresh lab machine with WSS 3.0 and SQL 2005. I registered the RS web parts.
In the home page I added the Reports Explorer and the Report viewer web parts. I set up the Reports Explorer and the list of reports are showed.
When I connect the Report Viewer Web part to get report from the Report Explorer web part I get the maintenance WSS page. I have to delete the Report Viewer web part to have the page working again.
If I use only the Reports Viewer with a report (not connected to Reports Explorer) is working just fine.
Any ideas what could be the problem? Any hints on how to investigate this is also much appreciated.
I'm trying to get webparts working with an sql 2000 database. I managed to get a database up and running using the aspnet_regsql.exe utility, enable forms authentiation, and user registration using asp 2.0 controls. Despite this success I seem to be getting a connection error when I try to display any page that has a web parts control. My thought is I need to specify a connection in the web part manager or some file other then the web.config.
Here's the error I get when I attemp to display a page with a webpart.
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)
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
SQLExpress database file auto-creation error: The connection string specifies a local Sql Server Express instance using a database location within the applications App_Data directory. The provider attempted to automatically create the application services database because the provider determined that the database does not exist. The following configuration requirements are necessary to successfully check for existence of the application services database and automatically create the application services database: If the applications App_Data directory does not already exist, the web server account must have read and write access to the applications directory. This is necessary because the web server account will automatically create the App_Data directory if it does not already exist. If the applications App_Data directory already exists, the web server account only requires read and write access to the applications App_Data directory. This is necessary because the web server account will attempt to verify that the Sql Server Express database already exists within the applications App_Data directory. Revoking read access on the App_Data directory from the web server account will prevent the provider from correctly determining if the Sql Server Express database already exists. This will cause an error when the provider attempts to create a duplicate of an already existing database. Write access is required because the web server accounts credentials are used when creating the new database. Sql Server Express must be installed on the machine. The process identity for the web server account must have a local user profile. See the readme document for details on how to create a local user profile for both machine and domain accounts.

The error message really confuses me. It seems to indicate that I'm trying to use SQL Express when I'm not. My only thought is the webpart manager doesn't know about the sql connection that has been established for the web application.
Since the applicaiton is connection for user authentication / creation using ASP2.0 controls I figured remote connections have been allowed for the server.
If anyone has any links to an example maybe I can mimic thier sample and resolve my problem.
"...Sharepoint sees the Report Viewer Web Part as a single item and will continually rename it sequentially as Report Viewer [x].... This is a limitation of SharePoint..." http://books.google.com/books?id=b0dXlx5aww8C&pg=PA314&lpg=PA314&dq=report+viewer+web+part+title&source=web&ots=U0MVGHySWU&sig=pGBgHh2gXYWcpuZMqttY7S9B65c&hl=en
If this is true then it applies also to the ReportExplorer webpart. Is there a current fix for SharePoint? Or is there a current fix for the webParts?
I can see customers complaining that they would like to see on their SharePoint ReportExplorer WebParts pointing to separate environments (SSRS) and multiple ReportViewer webparts pointing to different reports. Which would result in ReportExplorer [1], ReportExplorer [2],....ReportExplorer [x] and ReportViewer [1], ReportViewer [2],....ReportViewer [x].
Instructing customer's to ignore webpart title's and look at report names is NOT going to be acceptable. Especially since other webparts within Sharepoint behave differently.
Does anyone know the location of Microsoft.ReportingServices.SharePoint.UI.WebParts.dll after you install the web part? I am wondering if I can inherit from this web part to wrap some other functionality into it. I know that i see it in the GAC buyt can't seem to find it so I can look at the assembly using reflector.
Also, how easy is it to pass in parameters to the Report Viewer?
I just installed a fresh lab machine with WSS 3.0 and SQL 2005 SP1. I registered the RS web parts.
In the home page I added the Reports Explorer and the Report viewer web parts. I set up the Reports Explorer and the list of reports are showed.
When I connect the Report Viewer Web part to get report from the Report Explorer web part I get the maintenance WSS page. I have to delete the Report Viewer web part to have the page working again.
If I use only the Reports Viewer with a report (not connected to Reports Explorer) is working just fine.

I have a website with membership system. I've been through a lot implementing the site and I think I'm on the verge of full implementation. I can't get my registration page or my admin page to add, edit or delete users. I'm assuming that asp does not have proper permissions on SQL to do such. I'm running the site on a provider that has a SQL 2000 server. I access the database through VS2005 and SQL Server Management Studio Express. Is there a tutorial out there that could help a newbie to SQL understand how to check and correct my permissions issue (or find out that I'm haveing a different issue entirely. -Bill
Hi all, I`m a .NET desktop-app developer and i`m new to ASP.NET and web development, i start developping a web application with SQL Server database and i want to know if i can put all my tables in ASPNETDB? is any restriction with that? Regards
I am attempting to setup a membership instance for Site Server 3.0 using SQL 7 and try as I might, Site Server Membership will not see the server at all. I can do anything else I want to to that server and it works great (commerce, etc.). It all works OK under SQL 6.5 SP3 or later, just not SQL 7.
I am having problems deploying my web site from my machine to the hosting server.
Does any know of any special configurations that have to be perfomed before copying your web site to a server? All I have is a login in page that loads another page. The login page is launching okay but it does not load the second page.
I am upgrading my site from a VPS with a shared SQL server to a dedicated server and my own sql server 2003 standard. My site is an ecommerce site with about 10,000 users a month with between 10-20 people on the site at one time.
It is better to host both my site and the SQL server on the same system or is it better to have them on separate systems? if they are on the same system is 1 gig of ram enough? is will there really be much better performance with 2 gigs?
Any information on the best way to do this would be greatly appreciated!!!
I am trying access a FTP site present from a different server (remote work station). I am getting "The page cannot be displayed" error. I am able to access from my local machine.
I have setup a Flat File connection manager and set the location of the file as such:
ftp://10.1.1.1/FileName.txt
When I enter this URL into Start | Run on my machine it opens the txt file fine. Working in BIDS, when I create the flat file connection manager, it doesn't give me a message saying this file does not exist, indicating it is correct. When I create a flat file Source that uses the connection manager, the preview comes up blank. When I try to execute the step it gives an error saying it "cannot open datafile ftp://10.1.1.1/FileName.txt"
I need to place some site settings in my Report Manger.But in my Report Manager there is no Site Settings Icon.Is this installation problem please help me.
ive been playing around with encryption, just encrypting a column with a symmetric key, and having that symmetric key encrypted with a cert, and all that , and it works well through the SSMS, but i want to know how that will be used if im using sql server as a back end database for an asp web site, or an application. does the sql server have to be protected with an SSL cert, and once a user has logged in, what would the steps be to view encrypted data?
Hi! My problem is...i gut this errormessage in Web Site Administration Tool: There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store. The following message may help in diagnosing the problem: The database filename can not contain the following 3 characters: [ (open square brace), ] (close square brace) and ' (single quote)

I am wondering how some of you update your database once it is already been in use. So take for example you have a few tables and users can enter data into the site. Now suppose you either add tables to the db or you add fields to an existing table. I am using sql express 2005 and just want to copy the db over with the copy website but it would overwrite any data users entered.Is there any easy solutions or suggestions for this.Thanks
I'm getting the following error: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) Here's the setup: I have a website I've published on my server, but I haven't moved the SQL DB over to the server. For some reason the testing server can't connect with sql express on my computer. I have named pipes, tcp/ip both on, connections string is "Data Source=AMBA-176SQLEXPRESS;Initial Catalog=pubs;Integrated Security=SSPI"When I'm simply testing the site locally in visual studio it can connect just fine.
Rank newbie to ASP.NET here, so I'm totally "at sea" as to finding a "cookbook" for "how to deploy" a slightly customized version of the "Personal Web Site" project. My hosting service has an ASP.NET database installed. I can verify from their "SQL Server Web Admin" package that there are 11 "aspnet_" table names present. I have run the "personal-add.sql" script which has defined two (empty) tables -- "Albums" and "Photos". CONFUSION 1: The hosting service includes a Help fille for "Connecting to a SQL Server Database Using ASP.NET 2.0" which details the way to add 'connectionStrings' for "Personal" and "LocalSqlServer". I have made a "remote" copy of the "web.config" file and supplied the ostensively correct info for my Server, Database, User ID and Password. QUESTION: Why are there TWO names -- "Personal" and "LocalSqlServer"? Since all of the tables are contained now within the ASP.NET database are the details for both of these to be the same? CONFUSION 2: Error handling. I'm getting "An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine." Huh!? That page then goes on to mention "<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>". I've not a clue as to what "mycustompage.htm" should contain in order to field the error[s] erupting. POINTERS, anyone? Have I missed some basic part of the manual[s] someplace? I was sort of hoping that there would be a simple "cookbook" around someplace for how to "deploy" a relatively tested group of pages (application) in a relatively idiot-proof manner. I'm not finding it, so ANY pointers, hints, URLs will be greatly appreciated. Color me "confused in Kauai" ... :) KevInKauai
I'm interested in using the NEW security that 2.0 has. I had a table that has users, passwords stuff like that. But I wanted to try this new option. I ran "aspnet_regsql.exe" wizard, which updated the schema on my db. But when I go to Web site admin, and click on security tab, it states unable to connect to database. I have no database in my AppData folder. Do I need to just make my own connection with a data source, like I have done for everything elses, or is there a diffrent way?
Hi:I have a site that is getting close to production. I am using SQL Server 2005 express and VWD express. Up to this point, I have been updating the live server by deleting the file and copying the MDF file from my development machine in its place. This clearly won't work once the site goes live - but I still expect to be doing a lot of upgrading of stored procedures etc. Can someone point me to a resource or make any suggestions that would help me in this regard?Thanks,Roger Swetnam
I am developing a web site with asp.net 2.0 and c#, using Visual Studio 2005 and Microsoft SQL Server 2005 ( I am still learning about these technologies and languages ). I transferred my web site files to a new computer. I created a empty SQL database called "SiteData.mdf", I stopped the SQL server and then I replaced this database with a previous one with the same name and already populated with data. I used this maneuver in order to avoid having to insert all data again. The web site works fine when running inside Visual Studio, however when I try to run it in its published format it gives this error message: Server Error in '/MA' Application. Cannot open database "SiteData" requested by the login. The login failed.Login failed for user 'CENTAURUSASPNET'. I also observed that inside the SQL Server Management Studio, in the database properties, it shows "ETHERASPNET" as User or Roles ( however "ETHERASPNET" was created using the old computer's name [ or should I say domain ? ]) but the permissions list correctly displays the new name "CENTAURUSASPNET". I think that I, probably, should create a new user using the name "CENTAURUSASPNET" because it would use the name of the new computer ( or domain ) and then I should delete the old user name. Actually I tried to do that but I get the message "An object named ‘CENTAURUSASPNET' cannot be found". So, 1) What should I do to get the database being connected with the published web site ( note: I am publishing it in my own computer for awhile ) ? 2) How do I create the new user name "CENTAURUSASPNET" ? 3) I also would like to know why the name of the database in the Server Explorer panel of VS appears as "centaurus.SiteData.dbo" -while- inside the Object Explorer panel of the SQL Server Management Studio it appears simply as "SiteData" ?
