Hi all,
I have 512 on my machine at home 500Mhz and a 512 on my workstation at work
which is a 1.8Ghz machine.
Actually, the worst is the XML to Datagrid. I would think this would be
pretty fast.
For example:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button2.Click
Dim oAuthors As New Authors()
Dim oDS As DataSet = oAuthors.FillGrid()
With Me.DataGrid1
.DataSource = oDS
.DataMember = "authors"
End With
End Sub
Public Function FillGrid() As DataSet
Dim dsAuthors As New DataSet("authors")
Dim filePath As String
filePath = "C:\temp\xml\authors.xml"
Dim fsReadXml As New System.IO.FileStream(filePath,
System.IO.FileMode.Open)
' Create an XmlTextReader to read the file.
Dim xmlReader As New System.Xml.XmlTextReader(fsReadXml)
dsAuthors.ReadXml(xmlReader)
Return dsAuthors
End Function
There is a significant pause at the XmlTextReader(fsReadXml) line above.
This is an xml file with about 10 simple records in it.
1. Shouldn't this be pretty quick?
2. Given the code above, is there something I'm doing which is imparing the
speed?
Thanks,
