Database Connectivity Using SQL Server And ASP.NET In Visual Studio
Oct 19, 2005
Dear all,I am having trouble connecting my asp.net pages to a sql server database.I have the database running in visual studio and i can query it using the sql pane.My problem is that i don't know where to put the ADO.net query string or what it should look like.Does visual studio provide a wizard for doing this?Also is it possible to use CSS to change ASP.NET tags, i.e. asp:LabelAny help would be appreciated.Cheers

Hello
I'm having a problem with the server connection and my C# code. The code executes alright but no data is entered into the database behind it. I'm pasting the connection code over here as well. The sql commands are used in the code. I think I used the sql server mobile edition which is installed along with visual studio.net 2005. Anyone know what's wrong, and can help me out? Thanks in advance.public static void storeInDb(string trackName, string artist, string albumTitle, string year, string path, uint[] fp)
{
string connStr="Data Source=.\SQLEXPRESS;AttachDbFilename='"+path+"\Data\ACI.mdf';Integrated Security=True;User Instance=True";SqlConnection conn = new SqlConnection(connStr);
conn.Open();string sql = "INSERT INTO Clip(Song, Artist, Album, Year) VALUES('" + trackName;sql = sql + "','" + artist + "','" + albumTitle + "','" + year + "')";
SqlCommand cmd = new SqlCommand(sql, conn);
cmd.ExecuteNonQuery();
sql="SELECT max(ClipID) FROM Clip";
cmd = new SqlCommand(sql, conn);int id = Int32.Parse(cmd.ExecuteScalar().ToString());for (int i = 0; i < fp.Length; i++)
{
sql="INSERT INTO Hash VALUES ("+id+","+(i+1)+","+(int)fp[i]+")";cmd = new SqlCommand(sql, conn);
cmd.ExecuteNonQuery();
}
conn.Close();
}

I have a database in my "App_Data" folder of my visual studio project. I can view it fine in Visual Studio's built-in tools for managing a database attached to a solution. However i recently started playing around with the SQL Server Management Studio Express program. When i attach my database to Management Studio, and try to run my program it crashes. I think it might be a permissions error?!? When i detatch it and reattach it in visual studio it runs fine again. Any suggestions? ThanksJason

i need a regex support in SQL 2005 server.
i've downloaded SQL regex support project from http://msdn.microsoft.com/msdnmag/issues/07/02/SQLRegex/default.aspx?loc=en.
but in order to enable regex support i needed to open VS 2005. compile the project and deploy it to SQL server. now i can use Regexp-s in SQL queries.
However this is not elegant way to deploy everytime SQL Database project via Visual Studio to every MS SQL server i want.
my question is : how can i deploy without using Visual Studio?

Hi
I keep reading it's possible to add, amend ,etc. tables in visual studio but to do so I need access to the features that allow this.
I can connect to the database but I haven't been able to use any of these database features since they are "blanked" out.
Obviously, I can do all this at the server but ideally I would like to do it remotely.
Any suggestions?
Thanks in advance.

Hello,
I have visual studio 2005 installed on my PC. I want to create a new website and I want the site to be connected to a MS SQL 2005 database that resides on my hosting account. I am thinking this can be done but I have watched videos, spent time looking for a site to help and I have hit a brick wall.
I have no idea how to do this.
Can anyone please help me with some instructions or a webpage that shows you how to do this.
Thank You

I have created a database in Visual Studio 2005 by adding a new "SQL Database" item to my project, and then designing the tables with Server Explorer.
How can I add this database to my local instance of SQL Server Express, and to my SQL Server 2000 database engine?

Hi, I'm using SQL Express to run DotNetNuke on my own Windows 2003 server. DotNetNuke(DNN) copies a database on to the server from it's installation files and during the installtion process it fills the database with starter data. That process works fine.
But the minute I attach to the database in SQL Server Management Studio Express (MSE), my web app loses connectivity to the database. When browsing to the default.aspx, I see the following message:
Error Installing DotNetNuke
Current Assembly Version: 04.03.05
ERROR: Could not connect to database specified in connectionString for SqlDataProvider
__________________________________________________________________
(don't be fooled by the error message, Dot Net Nuke was fully installed and working before I attached to it with Management Studio Express)
Does anyone know the trick to getting the asp.net app talking to the database again? I'm using Windows Authentication. I have verified that Management Studio Express is what is messing up my connection. Any help is appreciated.
I have already become aware that I must disconnect from the database (in Management Studio Express) for the web app to connect properly. I have already tried that. Same error. So far for me, it seems that simply attaching to the database with Management Studio Express breaks my database connectivity.

I recently installed the Evaluation Edition of SQL Server 2005 x64 and it appears that MS Visual Studio 2005 is installed in stead of SQL Server Business Intelligence Development Studio. When I choose new project the only template available is "Blank Solution". How do I get all the templates (i.e. Analysis Server Project, Integration Services Project, Report Model Project, Report Server Wizard project, etc.)?
Or would it be better to uninstall MS Visual Studio 2005 and attempt to reinstall BIDS?

I am new to visual studio and I am still not sure of all its components and features.
I installed visual studio 2005 standard edition but cannot find SQL Server Management Studio?
I guess this must be because it is not included with Visual studio 2005 standard. Is it included with VS 2005 professional?
I want to add pictures of products to my shopping site using an SQL database and I’ve been told that SQL Server Management studio is required as it is a graphical tool.
How would I go about obtaining the SQL server management studio. There seems to be different versions of SQL server that it is confusing to know which one to purchase.
Will the SQL server 2005 version that comes with Visual studio standard be sufficient for me now right? I want to create a shopping site with hundreds, perhaps even thousands of products. I want to use an SQL server 2005 database. The database will include ‘dynamically generated’ product images if that is the correct terminology.
My goodness, it seems I still have so much to learn.
Thanks

When I try to create a database that will have fields for a date and a time the only data type option in visual studio is datetime. This stores data as dd/mm/yyyy-00.00.
how can I set it to store either a date dd/mm/yyy or a time 00.00 but not both.
As it is now I cant seem to store a time.

When I downloaded/started using Visual Web Developer I was under the impression that I needed to install SQL Server Management Studio Express in order to create/manage databases, and to provide the engine to access the data.
Since then I have found tutorials and have successfully created/used databases solely from within Visual Web Developer. I'm assuming that Visual Web Developer includes a database engine, much like the webserver that is included. (This is an awesome thing).
When I tried to upload my web application with database to my production server, the database would not work, it started working after I installed SQL Server Management Studio Express on the server.
Is it my understanding that you need SQL Server Management Studio Express if you do not have Visual Web Developer Express installed in order to provide the data access engine?
Also, I am unable to "attach" my Visual Web Developer Express created database to SQL Server Management Studio Express. Are there any posts that provide more information about this topic?
The only reason I'm asking is that I have extra whitespace on the end of my text fields, and I thought ANSI_PADDING was turned on. I do not see the option in Visual Web Developer Express, but have found it in SQL Server Management Studio Express.

I'm using Visual Studio 2005 Standard. I have an .mdf database inside my Visual Studio "Server Explorer" under "Data Connections."
How do I script out this database, including the stored procedures in it? In other words, I want to export a SQL script that will create this database.
I'm very much a newbie when it comes to working with database management. I thought I created this .mdf inside my local install of SQL Server 2005 Express, but maybe I did it somehow inside Visual Studio in the Server Explorer. When I open up SQL Server Management Studio Express I don't see this database. I did locate the .mdf on my local C drive but I haven't been able to get Mgt Studio to open it.

I can't connect to a SQL Server 2000 database using Visual Studio 2008. When I try to create a SqlDataSource in Visual Studio the db server isn't in the dialog box. When I manually create a connection string it doesn't connect.
When I go to the server, the db is running and apps that use it work fine. I can ping the server, and I can map a drive to it, but I just can't connect to the database. I tried using servername,port - didn't work.
I open SQL Server 2005 Management Studio and try to connect. In the Connect to Server dialog box, when I go to the Server Name dropdown and browse for my database server on the network, the server is not in the list. I tried entering the server name (and password, etc) but it doesn't connect. A different SQL Server 2000 database server does show up there.

I created an SQL database in Visual Studio 2005 Express Edition and would like to edit it in SQL Server Management Studio Express. The only databases listed in the Object Explorer of SQL Server MSE are the system databases (ones that are part of the SQL Server MSE).
If I dig through the directories, I can locate my database under the Visual Studio directory, but I am unable to open it. I get an error message stating, "There is no editor available for [my database]... Make sure the application for the file type (.mdf) is installed."
I'm sure that this is a ridiculously simple rookie mistake that I'm committing somehow, but I'm stumped. Any idea what I'm doing wrong?

string strCnn = "";SqlDataReader myDataReader = null;
mySqlQuery = "SELECT c_name FROM database WHERE c_user='demo'";
//connect to the databasestrCnn = "Data Source=" + connectionServer + "; Initial Catalog=" + connectionDatabase + "; user id=" + connectionUserID + "; password=" + connectionPassword + "; Integrated Security=false";cnn = new SqlConnection(strCnn);
try
{
cnn.Open();MessageBox.Show("Success Opening the Database");
}
catch
{MessageBox.Show("Problems with the database");
}SqlCommand sqlSelectCommand = new SqlCommand(mySqlQuery, cnn);
tbName.Text = "me";
cnn.Close();
This works, I just need to retrieve the value of c_name. Any help, thanks

I'd like to have the benefits of a VS 2005 Data Project (deployment, code snippets, etc.) but I can't figure out how to take an existing C# project and allow it to also be a Database project (there should be the extra "Data" tabe in the project's properties).
Any tips?

I receive the following error when trying to add a local database to my project.
"The data provider required to connect to the local data file could not found. The file will be added to the project but the typed DataSet associated with the file will not be generated."
I've reinstalled VS2k8, SQL Compact 3.1 and SQL Compact 3.5 on my machine and still receive the error.
Does anyone have any suggestions? I saw another similar thread about this in the VB2k8Express forum, but there were no helpful answers there. (for the curious: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2769854&SiteID=1)
I haven't used the SSCE before and so it's possible I've mistakenly omitted some required items.
Any help is greatly appreciated.

I use visual studio 2008 to design a database application.
I am in the peak of finalising the program but I have a snag with updating data in the database.
I could create new rows, add rows and new rows of data to the table but whenever i try to change the data in a cell
it returns an error "Update requires a valid UpdateCommand when passed DataRow collection with modified rows."
I have tried all possible solutions, using table adapter, commands etc but wont get it.
This situation also applies to changes made directly on the data grid and also when using the binding navigator buttons
to edit and save data.
please help me.

"Short" Story Version:
I have a VS 2005 Web Appplication solution that uses SQL Server Reporting Services 2005. One of the projects is a Report Server Project. In this project I have an RDL file that has:
1.)a non-shared XML DataSource (no credentials),
2.)a DataSet with a Command Type of Text and a Query String that is as follows:
<Query>
<XmlData>
<Root>
<LOAD LOAD_ID_PREFIX="" LOAD_ID="" TRUCK="" DIAGRAM=""/>
</Root>
</XmlData>
</Query>
3.)a field that comes from the Database that is of VarBinary(Max) that is a JPEG Image
What happens is, is that by doing #2 above, at design time I can create tables and hook into my datasets and get the report all designed out the way I want. Then at runtime, I have a Stored Procedure that uses the "FOR XML AUTO" option so that I can represent my results from the database in an XML fashion which will allow me to replace the XML Schema in between the Root tags above (in #2) with my actual data (which still has the same schema). I then save the modified RDL to a database table field and move on to happily ever after......in this case, not. In this case, since an VarBinary is involved, unless I want to get a pointer back for the Diagram Column, I have to use the "FOR XML AUTO, BINARY BASE64" option. This returns an Encoded string to represent the Binary value that was in the Database....and this is the partial source of my angst....read on.
My approach that I described above worked flawlessly in all cases where an image wasn't involved. This report is the only report in the whole system I am working on that will have an image and it is the last one being done, so that's why I didn't run into this earlier.
I have tried all kinds of things at different levels, but the thing that I have tried that seemed to me to have the most potential was to use Embedded Code to take the Encoded ASCII Value and convert into something binary that the SSRS Reporting Engine likes (so my image will show), but I have been unsuccessful thus far. The error message I keep getting now from my Embedded Function is: "Invalid length for a Base-64 char array", which I have not been able to resolve thus far....and I do know that the Binary value in the database is good becuase I can see it in pages in my application otherwise.
This aside, is there anyone out there that knows how to take the value of a VarBinary(Max) field and insert it into the Text (XML) DataSet in the markup of an RDL file....and have it appear correctly when the report is rendered in something like the standard Report Viewer Control (or even when being previewed at design time inside of Visual Studio for that matter)?
Just to be clear, the root of my problem, as I see and understand it, is that I have a VarBinary value in a database that is being converted to a string (ASCII...I am presuming) due to how I am writing my stored procedure and then needs to go back to something else binary that the SSRS Engine will accept so that I can see my Image in the report when I render it.
I am wishful that someone out there understands my problem and has run into this and has a solution......but I am wishful of winning the lottery, too, and that hasn't happened yet...............
Thanks.

Code Snippet
Hi there,
I'm struggeling for more than a week now with this problem, without a finding the solution.
I have two databases, MS Access and SQL Server 2005 Express Edition
Using a procedure in Visual Studio i would like to copy all the records from one table in MS Access into an existing table in SQL Server (the tables have the same name and the same layout)
I tried to prepare one Dataset to copy from Access into SQL Server but when i run the command 'DaSQL.Update(DsSQL, "Tabella") nothing happens (not even an exeption has been raised), looking during debug, the DataSet seems filled though...
Please could anyone explain what's wrong and / or is there a more quicker way to copy data from a table to another?
Note i woul have as a final goal to get data from an AS400 database by ODBC, manage it, and put it on SQL Server for a 'data mining' scope (eliminating the use of MS Access, not suited for FE-BE).
the procedure goes like this;
' Create a connection to the MS Access Database
Dim connectionToAccess As New OleDbConnection(DBConnectionAccString)
strsql = "SELECT * FROM [TABELLA]"
connectionToAccess.Open()
Dim DaAccess As New OleDbDataAdapter(strsql, connectionToAccess)
Dim DsAccess As New DataSet("ACCESS")
DaAccess.FillSchema(DsAccess, SchemaType.Source, "Tabella")
DaAccess.Fill(DsAccess, "Tabella")
' Create a connection to the SQL Database
Dim connectionToSQL As New SqlConnection(DBConnectionSQLString)
connectionToSQL.Open()
Dim DaSQL As New SqlDataAdapter(strsql, connectionToSQL)
Dim DsSQL As New DataSet("SQL")
DaSQL.FillSchema(DsSQL, SchemaType.Source, "Tabella")
DaSQL.Fill(DsAccess, "Tabella")
DaSQL.Update(DsSQL, "Tabella")
Note I tried also the following, withou a result;
DsSQL = DsAccess.Copy
DaSQL.Update(DsSQL, "Tabella")
Please is there someone who could respond !!???

Hi,
I have visual studio 2005 with the sql server express edition that is installed by default when installing vs2005.
I am used to work from within vs when I want to create and work with databases for my web sites (I dont have visual manager installed).
I would like to enable full text search on a table's column.
Is there an easy way to do that from within vs or is it necessary to install another copy of sql server express with advanced services as well as sql server managment studio express?
How can I know if full text search is enabled?
Thanx in advance!
