I have a database table called Qlinks, with two columns, URL and Name. This table is displayed on a form also called qlinks, in a details view. When I try to save data after i've deleted a row of the table, O get a yellow po-up telling me that the InvalidOperationException was unhandled. The error is "Update requires a valid DeleteCommand when passed DataRow collection with deleted rows." Please try to help, I am just a beginning programmer who doesn't know much. Code samples greatly appreciated. Thanks in advance.

I wrote code that connects to a SQL Server database in VB .NET The program connects to the server and works fine.
dConnection = New SqlConnection(getCfgProperty(fPropDBConnection)) dConnection.Open()
However when I put my code on to a different machine (test server) the program can not open the connection. It gives an exception in the dConnection.Open() line:
System.InvalidOperationException: The ConnectionString property has not been initialized. at System.Data.SqlClient.SqlConnection.Open() at Project4.HowTo.Samples.ADONET.ReportDistributor.di stributeReports()
Connection string is correct.
Is there something that has to be configured on test server environment?
I€™m developing a smart device application using VB.net 2005
First I created a class project containing a simple function
I built the project and added it as a reference in a smart device project (as a dll file)
The problem is when trying to use this dll reference I get this message (in a message box):
There is no source code available for the current location
Then I get this error message:
System.MissingMethodException was unhandled Message="File or assembly name 'System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089', or one of its dependencies, was not found."

I am using VWD2005 and SQLExpress 2005. In web.config I define the connection:<connectionStrings> <add name="ProFeeRevenueUser" connectionString="Data Source=.SQLEXPRESS;AttachDBFilename=|DataDirectory|ProFeeRevenue.mdf; Initial Catalog=ProFeeRevenue;User Id=whomever;Password=whatever" providerName="System.Data.SqlClient"/> When I try this code in a class (util.cs), I get an error on trying to open the connection:System.Data.SqlClient.SqlConnection cn = new System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings["ProFeeRevenueUser"].ConnectionString); System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand("usp_UserSystemRolesListByUser", cn);System.Data.SqlClient.SqlDataReader dr; try {cmd.CommandType = System.Data.CommandType.StoredProcedure; System.Data.SqlClient.SqlParameter retValParm = cmd.Parameters.Add("@RowCount", System.Data.SqlDbType.Int);retValParm.Direction = System.Data.ParameterDirection.ReturnValue;cmd.Parameters.AddWithValue("@UserLogin", userLogin); cn.Open(); // error occurs here <<---------------------------- dr = cmd.ExecuteReader();if (dr.HasRows) {while (dr.Read() == true) {string MyRole = dr[1].ToString().Trim(); SystemRoles.Add(MyRole); } dr.Close(); } It works fine if I point to a SQL server database on my server, but not with SQLExpress, so I assume I have done something wrong with the connection string or the SQL Express database. Any ideas?

My SqlConnection is causing an error "sqlConn.ServerVersion threw an exception of type System.InvalidOperationException". Everything I have read seems to suggest that there is a problem with my SQLConnection parameters but as you can see from the commeted code below I have tried three different servers with four different configurations. I am out of ideas on what is causing the error. Thanks - Amy Here is a section of my code: String sqlStmt = "Select [UserName], [Password], [Last], [First] from Contacts Where Login=@Uid AND Password=@Pwd"; SqlConnection sqlConn = new SqlConnection("Data Source=localhost;Initial Catalog=test;Integrated Security=SSPI;");//SqlConnection sqlConn = new SqlConnection("Data Source=pe2800;Initial Catalog=test;Integrated Security=SSPI;");//SqlConnection sqlConn = new SqlConnection("Data Source=HorizonDC02;Initial Catalog=test;Integrated Security=SSPI;");//SqlConnection sqlConn = new SqlConnection("Data Source=HorizonDC02;Initial Catalog=test;User ID=username;Password=password;"); SqlCommand sqlCmd = new SqlCommand(sqlStmt, sqlConn);sqlCmd.Parameters.Add("@Uid", SqlDbType.VarChar, 30).Value = uid;sqlCmd.Parameters.Add("@Pwd", SqlDbType.VarChar, 30).Value = pwd;sqlCmd.Connection.Open();
I've been looking around for some kind of known issue or something, but can't find anything. Here's what I'm experiencing:
I have a table with about 50,000 rows. I open several connections and use a command to ExecuteResultSet against each command, with CommandType.TableDirect, CommandText set to the name of the table, and IndexName set to various indexes. In the end, I have several SqlCeResultSet instances which are then maintained for the life of the AppDomain.
In a loop, I call SqlCeResultSet.Read() on one of the instances, and if it returns false, I call SqlCeResultSet.ReadFirst() - essentially creating a circular pass through the result set.
In a Visual Studio debug session, this approach goes swimmingly for a short time, and then after a successful Read(), I'm pegged with an InvalidOperationException (text: "No data exists for the row/column") for a column which was succesfully read on the previous Read(). If, in the immediate window, I call SqlCeResultSet.Read() again on the result set instance, the Get___ methods work as they had been in the previous reads.
It seems like the internal state of the ResultSet is getting corrupted somehow, but it is opaque to me. Any insights on why this suddenly throws this exception?
I have written a CLR Function in C#. The function works as expected except that I am trying to read data some data during the function call and get the following error:
Msg 6522, Level 16, State 1, Line 1

////////////////////////////////////////////////////////////////////////////////////////////////////////////// I executed the above project in my local PC (with Adiministrator previlidge/use) that is in our LAN/Network system and I got an error: SecurityException was unhandled - Request for permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'failed. First, I have a question: is this problem related to the remote connection to SQLEXPRESS? Second, I do not know how to solve this problem. Please help and answer my first question and tell me how to solve this problem.
I am trying to write a short application within which I would like to embed a SQL Server Express database, all of which would be deployed via ClickOnce through a web site. The installation process seems to be working without trouble, including installation of the .NET Framework 2.0 and SQL Server Express 2005.
When the application launches on the new machine, however, I get a big Microsoft .NET Framework "Unhandled exception" error dialog box that indicates the database already exists and that the database file could not be attached. I am working with a clean virtual machine that I know has never had the database installed on it.
I fear I am overlooking something quite straightforward, but since this is the first time I have ever attempted to build a data-bound application, I am not sure where I am going wrong.
Perhaps the source of the problem, or a related problem, might be revealed even when I run the application in debug mode from within Visual Studio. I can run the application once, but if I try to run it again, I get an error when I try to open the database connection that is similar in content (database already exists...could not attach). I can run the SSEUtil and detach the database and then run the application again in debug mode and it works no problem (the first time!).
Lastly, if I install the application on the machine on which it was developed and make sure the database is detached, it will run without any trouble (even repeatedly). But, on a new blank machine, there is no database listed that matches my database name, so I cannot try to detach anything!?
This could be a simple C++ issue as I am not that familiar with the language. I am trying to prototype a small program to test the performance of inserting data using the BCP interface. I want to BCP data that my program generates and passes via program variables.
I have narrowed the issue down to a sprintf call. Following are two variations of the code - one that works and one that does not. The error happens when I try to execute the bcp_sendrow() call.
What is the appropriate way to create / send string data to the BCP interface. Any good examples available? I have created the following from the BulkCopyFromVariables example on the Microsoft SQL Server downloads site.
While making a connection to a SQL server Enterprise Database using ASP.Net(C#), during execution of .aspx file i got the following error :-
Kindly help me if anybody knows the solution .
Thanks in advance

Found a similar problem in a different thread, but couldn't find any solution. I was wondering if there is an open case for this issue?
