SQLCommand Insert Netstat Results
Feb 8, 2012
I have a VB.net script that runs a simulation on several machines within the domain. During this simulation, a login is initiated to an application via a web portal. After the login, the connection to a specific Citrix server (whichever is least busy) is established. At this point, I want to run a Netstat -r | find (IP Range of server farm) in command line. From what I have deduced, I probably won't be able to do what I want from the command line and everything will have to be with in the VB.net module using System.Net.NetworkInformation. I am a Citrix Administrator with a decent level of .net experience but I am having trouble with this.

I have a datalist that returns multiple entries and I need to insert values via an OnClick command for a button I have with each entry. Problem is it's saying that a label I have in the datalist is not declared, in particular the MyLabel.Text from my Insert statement below.Can someone show me with code how I can declare this label or is it even possible? When I put the label outside of the datalist, everything works fine but when it's inside it says it's not declared. [code]...

OVERVIEW:I am currently having an issue loading a large number of rows into Excel. I say large because the attached code in fact correctly inserts 50 rows into an Excel worksheet, however, as the number of rows increases to no more than500 rows the data is not inserted into the worksheet. No error is thrown by .net and the .xls filesize actually shows an increase in size, however, when the file is opened there are no rows in the spreadsheet..... Then, when the .xls file is closed the filesize is once again reduced.
Again, the code works for a small number of rows. Are there any known bugs with the OleDB driver for Excel?ADDITIONAL THOUGHTS:I have tried inserting rows to both Excel 2003 and 2007, same issue.I have tried closing the connection after each insert.... performance if horrible and it does not fix the problem.I have wrapped the ExecuteNonQuery in a transaction.... no go....

I have an SqlCommand with parameters. Due to some external requirement (see PS), I need one T-SQL string instead, i.e., I need ... @parameter ... replaced by ... the-value-of-@parameter-encoded-correctly ... (e.g. O'Brien --> 'O''Brien', 02 Mar 2010 --> '20100302', 3.5 --> 3.5).
I know that I could home-brew such a solution quite easily, but correct escaping is tricky (make sure you get the right date and number formats, watch for quote signs in strings, etc.), and I guess that I'm not the only one needing this, so my question is:

Below is an UpDate Statement I am practising with David Sceppa's book ADO .NET 2.0 Core Reference pages 467 - 468. I can supply the parameter values for "parameter_New" by doing something like:
da.UpDateCommand.Parameters("@OrderID_New").Value = myTextBox.Text
And so on...My problem is how to supply the value of "paramete_Old" to be able to compare before update. I gues it has to do with obtaining the Original values of the rows based on RowVersion but I don't know how to effect it.
strSQL = "UPDATE [Order Details] " & _
"SET OrderID = @OrderID_New, ProductID = @ProductID_New, " & _
"Quantity = @Quantity_New, UnitPrice = @UnitPrice_New " & _

I fear that all of my code is a general mess, and I am sure there is a much better way to go about it.
Dim clsCmd As New SqlClient.SqlCommand
Dim clsCMAdapter = New SqlClient.SqlDataAdapter("SELECT * FROM CatalogMaster WHERE Processed <>-1", clsCnn)

I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?

I have a Stored Procedure which returns 10 columns of data. Using cmd.ExecuteScalar() returns the value of the 1st column from the 1st record. How can I change this so that I can return different columns, by specifying their alias/dataitem name?
I want to be able to do something like: Dim FirstName as String = cmd.ExecuteScalar("FirstName")

If there an easy way to get a completed SQL statement back after parameter substitution? I.e., I want to keep a logfile of all the SQL this program runs. Or if I want to do this, will I just want to get rid of Parameters, and do the whole query the old school way, in one big string? Simple Example: I want to capture the output:

I am almost finished building my application. All the data need is being inputted from various locations. I have a form that is suppose to consolidate all this data into a specific format. There are 47 fields that have to be populated and/or calculated based on two fields, the Username and a date range (this part is done). I was trying to set each of the TextBoxes equal to the SQLCommand that would return the proper value, but i am not calling it correctly. Would somebody please take look, is there something i am missing, do i need to write it in a function? I have had to use the Select statement itself in a couple of filters so I'm pretty sure that is correct, but i need help getting it to run the sqlcommand.[code]

In a for each loop I am adding rows to a table for a cross reference. Using the following code:
For Each cp In pCheckPoints
If cp <> String.Empty Then
Dim insertSQL As New StringBuilder
With insertSQL
.Append("INSERT INTO [CheckpointMessage] ( ")
Without the objCommand.CommandText = String.Empty line the CommandText is appending the insertSQL but that doesn't make any sense to me because I would expect the objCommand's commandText to be empty since it is in a using block.

I'm using the following select statement and it works fine but I need it to AutoComplete the results that contain the term as well and not just the results that start with the term. To clarify, if I type in "phrase" it won't AutoComplete the result "my phrase" but if I type in "my" it will. Anyone have a clue what I'm doing wrong? I've tried to use "contains @term" instead of "like @term" but

retrieve the actual T-SQL that is to be executed by a SqlCommand object (with a CommandType of StoredProcedure) before it executes...My scenario involves optionally saving DB operations to a file or MSMQ before the command is actually executed. My assumption is that if you create a SqlCommand like the following:
Using oCommand As New SqlCommand("sp_Foo")
oCommand.CommandType = CommandType.StoredProcedure
oCommand.Parameters.Add(New SqlParameter("@Param1", "value1"))
oCommand.ExecuteNonQuery()
End Using
It winds up executing some T-SQL like:
EXEC sp_Foo @Param1 = 'value1'
Is that assumption correct? If so, is it possible to retrieve that actual T-SQL somehow? My goal here is to get the parsing, validation, etc. benefits of using the SqlCommand class since I'm going to be using it anyway.

I have a stored procedure that repeats a block of T-SQL statements using WHILE logic until it finds a matching record in a table. When I execute the procedure directly from the SQL Management Studio, it works and returns a record, even when the statements within the WHILE logic have to be repeated over and over again before a matching record is found.
However, when I use the same stored procedure as the commandtext property of an sqlcommand object in Visual Studion 2008 (VB) and call the executereader method of the sqlcommand, the resulting SqlDataReader will only return a row if the T-SQL statements within the WHILE logic find a matching record after a single pass. If it takes more than one pass to find a matching record the SqlDataReader does not return a row. It's like it abandons the execution of the stored procedure after the first pass of the statements within the While logic, disregarding the repetition.

I've got a conversion utility that basically copies values from one table to another. It's worked great for a while, but I've run into a strange issue with one customer. They got through 1.5 million records with the utility but now it is completely halted.When calling a stored procedure from VB.Net, it just hangs until the SqlCommand times out.Calling the same sproc from Management Studio executes instantly. My VB.Net code for the SqlCommand is below (insertConn is defined and opened earlier, dr is a SqlDataReader that has been populated in a previous step from completely different SqlConnection and SqlCommand instances):
Dim conn As New SqlConnection("connection string here")
Dim insertConn As New SqlConnection("connection string here")
Dim dr As SqlDataReader = Nothing

I'm calling Sqlcommand.ExecScalar() - stepping through the stored proc works fine, right under
RETURN @RecordNum
@RecordNum correctly contains a bigint, as scoped. When I step into the RETURN.. I get an exception thrown, that visual studio does not seem to be able to capture.
The stored procedure works fine when executed directly, and returns a value without problem, and it seems like all is well, stepping through it from my code.
But as soon as I step into 'RETURN @RecordNum' (and recordnum contains a valid number..) BOOM! EXCEPTION! (and no details in the exception either back in visual studio.
I'm blaming a glitch in the matrix.
I've turned off even assigned the return from the ExecScalar to anything, same result.. I've tried ExecReader(), same result. I have turned NO COUNT on and off, same result. If I wasn't already bald, I would be now!

I have three ways of adding parameters to my query commented out above. The all seem to return 1781 records (which is all of the records) and will not filter out to what the UserName variable equals which should reduce it to 32 rows.
I use a Console.WriteLine to show that the UserName is indeed my username. But it seems to not be getting passed to the query properly. I tested the Stored Procedure before even starting in on the program, so I know it functions properly. I just don't know what I'm missing from a VB.NET perspective to get the same results into my DataTable.
