... wish all of you are having a nice Valentine's Day .. For me, I am stack at work finishing my program.
I have a piece of code to write an xml file.
Dim ds As New DataSet
Dim dt As DataTable = GetDtable()
ds.Tables.Add(dt)
Dim filename As String = Server.MapPath("XmlDoc.xml")
Dim writer As New System.IO.StringWriter
dt.WriteXml(filename, True)
That work will write an XML file whatever I put in the datatable (or dataset). It is just a simple code and it works fine.
The problem is it will replace the old file everytime the new file is created. I really don't want that to happen.
I also want to include 2 variables (username, sessionID) also time of the file created in the file name.
So file name will be Username_sessionID_time.xml rathen than a fixed name.
Can anyone tell me how can i do that ?
thanksssssssss so much.
Assuming Username and SessionID are strings with no illegal file name characters, you can simply concatenate them when you define the value for the filename variable...
Dim filename As String = Server.MapPath(username & "_" & sessionID & "_" & Replace(DateTime.Now.ToString(), "/", "-") & ".xml")
