Why do I get this error write I write OPTION STRICT ON? with this code

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
XmlSchema11.ReadXml(Application.StartupPath & "\..\Data\GRID.XML", FileMode.Open)
End Sub

Private Sub Form1_Closed(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Closed
XmlSchema11.WriteXml(Application.StartupPath & "\..\Data\GRID.XML", FileMode.Open)
End Sub

I get this error:

C:\Documents and Settings\Telemetrika.Com\Desktop\XMLGrid\Form1.vb(111): Overload resolution failed because no accessible 'ReadXml' can be called with these arguments:

It tells you exactly why.

'Public Function ReadXml(fileName As String, mode As System.Data.XmlReadMode) As System.Data.XmlReadMode': Option Strict On disallows implicit conversions from 'System.IO.FileMode' to 'System.Data.XmlReadMode'.

There is no ReadXML that takes System.IO.Filemode as a paremeter. It uses Syste.Data.XmlreadMode

Because Option Strict On doesn't allow any implicit conversions. That means that it won't be able to look at "FileMode.Open",which is actually "System.IO.FileMode.Open" which has a value of 3, and convert it to a "System.Data.XMLReadMode". The equivelant "System.Data.XMLReadMode" value to "FileMode.Open" is "System.Data.XmlReadMode.InferSchema".

HTH.

LOL Cander. You beat me to the punch. ;)

:D

How should I re-write the Load Form event then?

Turn OPTION STRICT off and try , Or there's nothing wrong with your sub , you should pass the right data type .

Pirate:


The sub works just fine When I turn Option Strict Off.

I need Option Strict to be ON so what can I do to make this sub work.

Should I attach a small example?

We already answered the question. Sheppe in particular.

What SUB are you getting problems with (your code is unreadable without vb tags)? again if the program is working well , keep OPTION STRICT off .

Do what pirate said. Pass in the right data type.
