What kind of validation are you performing? Are you working with VB6/VB.NET?

Hi,
Im trying to search through an XML file. When it finds the record it needs it then updates a specific field in that record. I have made it find the specified record but do not know how to update it and write it back to file. I am new to XML coding. Any help would be most appreciated.
Dim xpathDoc As XPathDocument
Dim xmlNav As XPathNavigator
Dim xmlNI As XPathNodeIterator
Dim filePath As New OpenFileDialog
filePath.ShowDialog()
xpathDoc = New XPathDocument(filePath.FileName)
xmlNav = xpathDoc.CreateNavigator()
xmlNI = xmlNav.Select("/Message/Pupils/PupilCode")
While (xmlNI.MoveNext())
System.Console.WriteLine(xmlNI.Current.Name + " : " + xmlNI.Current.Value)
If (xmlNI.Current.Value) = "A123981456002" Then
'ONCE ITS FOUND THE RECORD - DISPLAY A MESSAGE
'SELECT THE DIFFERENT FIELD WITHIN THE RECORD
MsgBox("Found")
xmlNav.Select("/Message/Pupils/PupilAge")
'THIS IS WHERE IT NEEDS TO UPDATE IT. NO IDEA HOW TO DO THIS BIT
End If
End While
This may be the wrong way to do it - I'm not sure. I just need it to search for a specific pupil ID and update their age with a specified value. After that it has to write the entire XML file to a new file.
Many thanks.

I developed a project that generates a xml file form a database and upload it to a webserver. I think it is possible to check the generated xml file having virus or any harmful threat. So i want to trigger the anti virus software to scan that xml file and if no threat was found then upload that file or inform that the file has a virus.
Please any of one help me to accomplish this task, the main thing is the source must be in VB 6.0 :(code.

You don't have to. With most antivirus software, the file is scanned when written to the hard drive.
Besides, with all the different versions out there, and all the different API's they MIGHT expose, your idea will be a nightmare to implement. There is no generic interface to launch a scan of a file without having to know what anitivirus software is installed.

Virii in XML files? That's strange. XML is a text format, how would it be possible to write virii using it?

Hi everyone!
I'm using this great code above (that I downloaded here) but it's returning the HTML code with one "?" for each "," "ç" "ã" "ô" etc... I think it's related with unicode, but I don't know what to change. 
Function GetHTML(ByVal strPage As String) As String
Dim oReq As System.Net.HttpWebRequest
Dim oResp As System.Net.HttpWebResponse
oReq = System.Net.HttpWebRequest.Create(strPage)
oResp = oReq.GetResponse
Dim sr As New IO.StreamReader(oResp.GetResponseStream)
Return sr.ReadToEnd()
end function
Thanks in advance!

I usually set my DataSource to a DataTable in the DataSet (lst.DataSource = ds.Tables("MyTable")) or to a DataView. Then the binding code is:
<%# DataBinder.Eval(Container, "DataItem(""MyFieldName"")") %>

I believe, that you must provide information about the database location, user name, and password. '

Where did you create the rpt?

im sure its possible to open up a dll during runtime so you can somewhat explore what objects are in it, but how do you do it? ive tried messing around with things in the System.Reflection, mostly with the Assembly object in that, but cant seem to figure it out.
any ideas?
thanks

It's fairly straightforward, look for the System.Runtime.Reflection namespace. You'll find Assembly.LoadXXX methods to load an assembly. Those methods return an Assembly reference, on which you can call GetTypes(). You can then iterate through the Type array returned by it and display whatever information you want to.

PeriodAdapter.Fill(DataSet11, "period")
Dim datatable As DataTable = DataSet11.Tables("Period")
Dim dr As DataRow = datatable.NewRow
Dim r() As DataRow = datatable.Select("periodno= max(periodno)")
Dim i As Integer
For i = 0 To r.Length - 1
dr("periodno") = CInt(r(i)("periodno")) + 1
dr("begindate") = DateTimePicker1.Value.Date
dr("enddate") = DateTimePicker2.Value.Date
datatable.Rows.Add(dr)
Next
MsgBox("New period has been saved", MsgBoxStyle.Information, "New Period")
PeriodAdapter.Update(DataSet11, "period")
--------------------------
Well i havent search from internet about this fucntion yet and above code is just what i modify a bit and use for generate new id or number to my record by adding 1. The problem is if there are not records at database, above code cannot add the first record let said periodno =1 ........... and keep giving blank record when i see at my database. if i manually insert periodno=1 then above code can give the next periodno=2.
How to make condition if my database is empty, i tried use Nothing syntax also cannot. What should i do....

Hi,
first of all: If your periodno is unique you won't need the loop.
To your question: If you don't have any entries in the Period table the Select function will return an empty array:
PeriodAdapter.Fill(DataSet11, "period")
Dim datatable As DataTable = DataSet11.Tables("Period")
Dim dr As DataRow = datatable.NewRow
Dim r() As DataRow = datatable.Select("periodno= max(periodno)")
Dim nextPeriodNo as Integer
If (r.Length == 0) Then
nextPeriodNo = 1
Else
nextPeriodNo = CInt(r(i)("periodno")) + 1
End If
Dim i As Integer
dr("periodno") = nextPeriodNo
dr("begindate") = DateTimePicker1.Value.Date
dr("enddate") = DateTimePicker2.Value.Date
datatable.Rows.Add(dr)
MsgBox("New period has been saved", MsgBoxStyle.Information, "New Period")
PeriodAdapter.Update(DataSet11, "period")

Hello there
I am creating a folder(s) on the server through my application and want no one to access that folder without providing a password on it. even administrator has to provide the folder(s) password before accessing it.

It is possbile but requires your to write a file system extension. This is NOT easy and requires a deep understand of the internals of NTFS and COM.
Your first step is to order the Windows Device Driver Development kit.
