VS 2010 - Web Page Error When Connecting To Database (permissions)

Dec 9, 2010

My website is [URL] (access there to see error, please) When I was testing in VS2010, it was connecting to the DB because I set permissions READ/WRITE on my computer to ALL. If I put restrictions, VS2010 couldn't just connect to them. Well, I deployed my DB on the server of my website, and I'm not able to access it.

My connection string:

connection = New SqlConnection("Data Source=.SQLEXPRESS; Integrated Security=True;AttachDbFilename=|DataDirectory|Visitas.mdf")

I think I'm getting these errors because my server hasn't permission to access the database.

VS 2010 Connecting To SQL Database From Windows Form Application?

Aug 5, 2010

I had another thread on this problem but I wanted to start this one so no one had to look at the code I posted in the other thread. I have a successful connection but want to display data from the SQL database on my website in my Windows form application. Here's the code I have so far. Used some of the ADONET Tutorial1 here. The table Ray Rover Activation has a number of different columns but to start out I just wanted to see if I could display data for the EmailAddress column.



If I comment out the Sub DoStuff I don't get any errors but neither is anything displayed other than the messagebox message. If I don't comment out DoStuff then I get an error, "Incorrect syntax near the keyword 'FROM'". Maybe someone could enlighten me some on what I need to do get the data in the column EmailAddress to display.

Configuration :: Getting Error Connecting To Database After Upgrading To .net 4.0?

Aug 22, 2010

I upgraded a Website to use ASP.NET 4.0, from 3.5. This involved setting it up on a different server, with the same hosting company. I'm using a shared hosting plan on Windows Server 2008.

Since migrating, it gives an error message when I try to login to the site:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

I'm using the same connection string as I did in the old version, which always worked. I also changed the permissions for the database to allow connections from the redeployed Website, via the host's control panel.

I have searched the web.config, and the source for the site, and I haven't been able to find a connection string that looks incorrect.

I've contacted the host about it, in case it is a configuration issue on their side.

SQL Reporting :: Connecting To Database - Error "Could Not Retrieve Schema Information For Table Or View"

Jun 3, 2010

Well it's finally time to stop ignoring my unit's need for reports. I keep coming to dead ends. I gave up the crystal reports idea, and ssrs seems a little easier. Now the problem is that I'm creating a report locally on my laptop, then will change the connection string, upload it to my server and have it run against an identical database on the server.

I'm using SQL Server Express locally, and when I try to create a dataset (using the wizard), I can see the tables, but when I try to add one, I get an error message "Could not retrieve schema information for table or view". I looked up this error and there isn't much useful info on it. I guess it some bug when trying to use SS Express? Is there a work around for this? Can I create the report programmatically? Should I use a different kind of reporting service?

Adding A Work Item To TFS 2010 From .NET App Fails Due To Permissions?

Feb 16, 2011

I'm working on an ASP.NET webforms app that will serve as a simple intake form to create work items in TFS 2010.The app works correctly when I run it locally in debug mode--the submission completes and the work item is created.

When I publish the form to our dev server, it yellow screens and throws the following error:

[SecurityException: TF50309: The
following account does not have
sufficient permissions to complete the
following permissions are needed to
perform this operation: View
collection-level information.]

In my code, I'm attempting to access TFS using a service account, and from what I can tell the service account is being used correctly when I run in debug mode.Here's what my C# looks like:

string tfsServerUrl = "http://servername:8080/tfs";
string tfsProject = "Web Team Projects"; [code]....

If I set a breakpoint at the tfs.Authenticate() line, the server object shows the service account name as the current user and IsAuthenticated = true.

The line in the exception that mentions SERVERNAME$ is what's stumping me. It's seems like IIS is deciding to try to access TFS with the app pool identity instead of the credentials that I'm explicitly supplying.Our dev server is a Server 2008 box running IIS 7.

Visual Studio :: Connecting Vwd 2010 To Remote Iis 7.5?

Aug 9, 2010

How do I connect to a remote site in IIS 7.5 using vwd 2010? vwd 2010 appears to be looking for deprecated software instead of the IIS 7.5 supported protocol using webdav. My application uses a cookie authentication from a central corporate authority and nothing but a legitimate URL is going to work during debugging. There is almost no information in a google search and the only forums.asp.net post from last year says it isn't possible. If MS is no longer supporting FPSE in the new versions of IIS, then what is vwd 2010 doing looking for it--is there a patch or module of some kind that is available to enable webdav access?

I've changed permissions several time on the server (2008/IIS 7) and still the problem persists. I have other directories that have javascripts and when I put the path into the browser for them I get the source.

Configuration :: Sending Email & IIS 7 Permissions Error?

Aug 21, 2010

I'm trying to send an email. My code is fine, but I'm getting a permissions error:

This is a server I'm administering myself, so I have access to the IIS 7 panel. The trouble is I don't know what to set to get mail working. Anyone got any experience of this?

My permissions error:

Access to the path 'c:7c5658db-d4cd-40cf-a686-6e9630e287f9.eml' is denied.

Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access to the path 'c:7c5658db-d4cd-40cf-a686-6e9630e287f9.eml' is denied.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access._______________________________

ADO.NET :: Connecting To A Database With .NET ?

Jan 17, 2011

I come from a coldfusion background, where setting up a connection to a database (Oracle, MYSQL SQL Server etc) was was easy as filling in a few fields in the datasource screen in the Coldfusion Administrator web app.

Then in the web application to connect to the database I would use <CFQUERY datasource="oracledb" name="test"> and in the body of the application I would write my SQL query and display the results of this query in a <CFOUTPUT>#variablename#</cfoutput> block of code, or to insert data into a db table I would use the

<CFQUERY datasource="oracledb" name="insertdata">
INSERT INTO table (columnname, columnname2, columnname3)
<cfqueryparam cfsqltype="cf_sql_number" value="#columnname#">,
<cfqueryparam cfsqltype="cf_sql_varchar" value="#columnname2#">,
<cfif isdefined("file.serverFile")>'#file.serverFile#'<cfelse>NULL</cfif>,

How does this process work in .NET? as I have to create a simple web application/form where on submission of the form the data would be stored in a MYSQL database.

what I have seen so far it seems a far more long winded and complicated process with .NET over Coldfusion with ultimately the same result, and I am desperately trying to understand how it works in .NET as surely it must be a similar process to that of Coldfusion?

Security :: Impersonation Error / .NET User Account Has To Be Given Permissions To Access The Folder

Jun 18, 2010

I wrote an asp.net application that I'm trying to run on a godaddy domain I bought. I need to read a file in a folder that I did not give read access to so that your average user cannot see in the informaion in that folder. I assumed that the asp.net program would have the same credentials as myself because server-side code. Turns out I am wrong. When I go to use the asp.net application it throws an access denied error saying that the ASP.NET user account has to be given permissions to access the folder.

After talking to two different tech support people at godaddy I've come to the realization that they are either dumb or lazy (or a combo of the two).I came across some code that you can put into the web.config file that would allow the asp.net application to impersonate a user, which would work great to use myself as the impersonated user. However it seems that godaddy cannot give me the name of the server that my domain is on (that's understandable) so I don't know what to put in the identity tag to get this to work.

Here is the code I found:


(of course I filled in the username and password with the correct info)

When I went to use it again it threw this error:

System.Web.HttpException: The current identity (PHX3username) does not have write access to 'C:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files'.

Connecting To Database - Can't Upload

Jun 12, 2010

I'm trying to learn how to do both of them at the same time on my own, while working on a project. All the examples in the MSDN are using databases that are a local SQL Server (Express) file. I am not going to be able to just upload the project (including the file) and have it work, am I? The thing is - I want to be able to write code vs. a database that is actually going to work online so I can start putting a project together and know that it is going to work online.

I don't want to get everything done, and then discover it breaks as soon as I upload everything. Assuming I can't just upload the database file and have it work - I have a hosting account that I am using for something else and I would like to set up a database to use (preferably MySQL because my SQL Server database quota is used up and I'd have to pay extra for another, but I will if I have to because it's not that much). I can do that, correct?

SQL Reporting :: Connecting To A Database

I have never used reporting services before. My boss just started teaching me how to use them. I was told something by my boss that I find hard to believe. In our environment we have 3 databases: Development Beta Production According to my boss, the connection string has to be hard coded in the reports. Therefore every time you move a report from one environment to another you have to manually change the connection string so that it points to the correct database.
