unable to write to file

Hi..
I am trying to create a xml file and write some information into the xml file but when i open the xml file i don't have any information.
Even if i try to create a txt file and do the same thing but it is still the same.
i am not sure why..
can someone help me...

VB Code:

Dim path As String = "School"
        Dim target As String = "School/latcomers.txt"
 
        Try
            If Directory.Exists(path) = False Then
                Directory.CreateDirectory(path)
                Dim sw As StreamWriter = File.CreateText(target)
                sw.Write(("<info class=""1A"" indexno=""01"" date=""10/10/2005"" time=""10:18:00""/>"))
 
            ElseIf Directory.Exists(path) = True Then
                Dim sw As StreamWriter = File.CreateText(target)
                sw.Write("<info class=""1A"" indexno=""01"" date=""10/10/2005"" time=""10:18:00""/>")
            End If
 
        Catch ex As Exception
            MsgBox("unable to create")
        End Try

:) Thanxs......

Why are you creating XML file with the streamwriter.
Have you looked at System.XML and the XMLWriter???? this is really what you should use for creating xml files



however to create and write to file:

VB Code:

Dim l_sWriter As New StreamWriter(target)
Dim l_writeLine As String
l_writeLine = "<info class=""1A"" indexno=""01"" date=""10/10/2005"" time=""10:18:00""/>"
 
l_sWriter.WriteLine(l_writeLine)
l_sWriter.Close()

ya.
I tried using the xmltextwriter, but i am very cofused because when I add the codes:

Dim w As XmlTextWriter = New XmlTextWriter(target, )

in the brackets (target is my filename, after the commer as stated in the constructor there shlould be (encoding As System.text.Encoding) but i don't need that)
So, i am not sure how to place the codes such that it will write to my xml file using the xmlwriter or xmltextwriter.... :cry:

Thanxs 4 helping...
:)

there is no need for encoding, all you need to do is pass "Nothing" into it.

here is a sample

VB Code:

Try
            Dim l_xmlWriter As New XmlTextWriter(p_file, Nothing)
 
            l_xmlWriter.Indentation = 1
            l_xmlWriter.Formatting = Formatting.Indented
            l_xmlWriter.WriteStartDocument(True)
            l_xmlWriter.WriteComment("Created: " & Date.Now.ToString)
 
            l_xmlWriter.WriteStartElement("Config")
 
            l_xmlWriter.WriteStartElement("DeviceLocations")
            l_xmlWriter.WriteStartElement("HHImport")
            l_xmlWriter.WriteAttributeString("Value", p_settings.HandheldImportDirectory)
            l_xmlWriter.WriteEndElement()
 
            l_xmlWriter.WriteStartElement("HHExport")
            l_xmlWriter.WriteAttributeString("Value", p_settings.HandheldExportDirectory)
            l_xmlWriter.WriteEndElement()
 
            l_xmlWriter.WriteEndElement() 'End Device Locations
 
            l_xmlWriter.WriteStartElement("ServerLocations")
            l_xmlWriter.WriteStartElement("PCImport")
            l_xmlWriter.WriteAttributeString("Value", p_settings.PCImportDirectory)
            l_xmlWriter.WriteEndElement()
 
            l_xmlWriter.WriteStartElement("PCExport")
            l_xmlWriter.WriteAttributeString("Value", p_settings.PCExportDirectory)
            l_xmlWriter.WriteEndElement()
 
            l_xmlWriter.WriteEndElement() 'End Server Locations
 
           
            l_xmlWriter.WriteEndDocument() 'end node
 
            l_xmlWriter.Close()
        Catch ex As IO.IOException
            Throw New Exception(ex.Message)
        Catch ex As XmlException
            Throw New Exception(ex.Message)
        Catch ex As Exception
            Throw New Exception(ex.Message)
        End Try

Why have you got so many catch in there?

sorry dude, must have got carried away

its a bit of overdosing on catches alright

lol....

anyway.....isn't try and catch strongly discouraged because it uses up alot of resources?

never knew that is used up so much resources i've seen how something it can take a while for it to throw the exception alright


i generally use then a lot with files because i always find that there is always some error with some data in them

really there should only be one catch in the code above....
