The GOTO statement in T-SQL allows you to transfer control to a labeled line of code within a stored procedure or a batch. The labeled line is identified by a unique label name followed by a colon (:). Here is an example of how you can use the GOTO statement in T-SQL:
DECLARE @Value INT = 1
IF @Value = 1
BEGIN
PRINT ‘Value is 1’
GOTO EndOfCode
END
PRINT ‘Value is not 1’
EndOfCode:
PRINT ‘End of code’
In this example, the IF statement checks if the value of the @Value variable is equal to 1. If the value is 1, the PRINT statement outputs “Value is 1” and control is transferred to the labeled line of code identified by EndOfCode using the GOTO statement. The execution continues from that line and the PRINT statement outputs “End of code”.
It is important to note that the use of the GOTO statement is generally discouraged in T-SQL programming as it can make the code difficult to understand and maintain. It is recommended to use structured control flow statements such as IF, WHILE, and FOR instead of GOTO.
Clean the solution: Sometimes, cleaning the solution can resolve performance issues in Visual Studio. To do this, go to Build > Clean Solution.
Reset Visual Studio settings: If your Visual Studio settings have become corrupted, you can reset them to the default settings. To do this, go to Tools > Import and Export Settings > Reset all settings.
Delete the suo file: The suo file is a hidden file that stores Visual Studio settings. Deleting the suo file can help resolve performance issues in Visual Studio. To do this, close Visual Studio, locate the suo file in the solution folder, and delete it.

To load an XML string into a DataSet in VB.NET, you can use the following code:
Dim ds As New DataSet()
Dim xmlString As String = “” & _
“” & _
“Nava” & _
“FP0100001” & _
“2022-12-17” & _
“” & _
“” & _
“”
Dim sr As New StringReader(xmlString)
ds.ReadXml(sr)
The StringReader class allows you to read data from a string as if it were a stream of characters. After reading the XML data into a DataSet, you can set it as the data source for a DataGridView control
The error message “Illegal characters in path” usually occurs when the path to a file contains invalid characters.
In this case, it could mean that the path to the XML file contains characters that are not allowed in a file path. For example, the following characters are not allowed in a file path: \ / : * ? ” < > |
To resolve this issue, you can modify the file path to remove the invalid characters. Additionally, you can encode the file path as a URL and then decode it back to a file path to ensure that all characters are valid.
Here’s an example of how to encode and decode a file path in VB.NET:
Dim xmlFilePath As String = “C:\Example\File.xml”
Dim encodedFilePath As String = Uri.EscapeDataString(xmlFilePath)
Dim decodedFilePath As String = Uri.UnescapeDataString(encodedFilePath)
Convert Object To Datatable
Private Sub LoadDataGridView()
Dim recordList As List(Of Record) = GetRecordList() ‘Get a list of Record objects
Dim dt As New DataTable()
‘Populate the DataTable with data from the Record objects
For Each rec As Record In recordList
Dim row As DataRow = dt.NewRow()
row(“POSName”) = rec.POSName
row(“BillNo”) = rec.BillNo
row(“Date”) = rec.Date
row(“Time”) = rec.Time
row(“SubTotal”) = rec.SubTotal
row(“DiscountAmount”) = rec.DiscountAmount
row(“GrandTotalAmount”) = rec.GrandTotalAmount
row(“Taxes”) = rec.Taxes
row(“SettelementMode”) = rec.SettelementMode
row(“TransactionStatus”) = rec.TransactionStatus
dt.Rows.Add(row)
Next
‘Set the DataTable as the data source for the DataGridView control
DataGridView1.DataSource = dt
End Sub
Console.WriteLine(“Press enter to exit”);
Console.ReadLine();
}
}
}
This example creates a simple math service that can perform addition and subtraction operations, and makes it available over the network using the TCP protocol. The MathService class is decorated with the MarshalByRefObject attribute, which makes it possible to call its methods from a remote client.
The RPCServer project contains the code for the server, which registers the MathService class with the .NET remoting framework and makes it available over the network. The RPCCLient project contains the code for the client, which uses the .NET remoting framework to call methods on the remote MathService instance.
