Im using VS2010 professional and am trying to teach myself how to use an XML file to store information.

I have added an XSD file to the project with the following code:
Code:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="Study_Aid_Schema"
    targetNamespace="http://tempuri.org/XMLSchema1.xsd"
    elementFormDefault="qualified"
    xmlns="http://tempuri.org/XMLSchema1.xsd"
    xmlns:mstns="http://tempuri.org/XMLSchema1.xsd"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
>
  <xs:element name="Study">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="Subject" minOccurs="1" maxOccurs="unbounded">
          <xs:complexType>
            <xs:sequence>
              <xs:element name="Title" type="xs:string" minOccurs="1" maxOccurs="1"></xs:element>
              <xs:element name="Topic" minOccurs="1" maxOccurs="unbounded">
                <xs:complexType>
                  <xs:sequence>
                    <xs:element name="Title" type="xs:string" minOccurs="1" maxOccurs="1"></xs:element>
                    <xs:element name="StudyAid" minOccurs="1" maxOccurs="unbounded">
                      <xs:complexType>
                        <xs:sequence>
                          <xs:element name="Box" type="xs:integer" minOccurs="1" maxOccurs="1"></xs:element>
                          <xs:element name="LastLearned" type="xs:date" minOccurs="1" maxOccurs="1"></xs:element>
                          <xs:element name="TimesLearned" type="xs:integer" minOccurs="1" maxOccurs="1"></xs:element>
                          <xs:element name="CorrectAnswer" type="xs:string" minOccurs="1" maxOccurs="1"></xs:element>
                          <xs:element name="Field1" type="xs:string" minOccurs="1" maxOccurs="1"></xs:element>
                          <xs:element name="Field2" type="xs:string" minOccurs="1" maxOccurs="1"></xs:element>
                          <xs:element name="Field3" type="xs:string" minOccurs="1" maxOccurs="1"></xs:element>
                          <xs:element name="Field4" type="xs:string" minOccurs="1" maxOccurs="1"></xs:element>
                          <xs:element name="Field5" type="xs:string" minOccurs="1" maxOccurs="1"></xs:element>
                        </xs:sequence>
                      </xs:complexType>
                    </xs:element>
                  </xs:sequence>
                </xs:complexType>
              </xs:element>
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>
I've also added an XML file to the project and set the schema to Study_Aid_Schema.xsd in the properties pane. The XML file contains the following code.
Code:
<?xml version="1.0" encoding="utf-8" ?>

<Study>
  <Subject>
    <Title>SampleSubject</Title>
    <Topic>
      <Title>SampleTopic</Title>
      <StudyAid>
        <Box>0</Box>
        <LastLearned>2011\03\02</LastLearned>
        <TimesLearned>0</TimesLearned>
        <CorrectAnswer>A</CorrectAnswer>
        <Field1>This is the sample questions for sample 1</Field1>
        <Field2>This is the Sample A answer</Field2>
        <Field3>This is the Sample B answer</Field3>
        <Field4>This is the Sample C answer</Field4>
        <Field5>This is the Sample D answer</Field5>
      </StudyAid>
    </Topic>
  </Subject>
 </Study>
But when I try to access the information in the XML file with a data set I get the schema information for element not found error for every element in the XML file. This is the code I am using to try and access the data.
Code:
Public Class Form2
    Private DS_Aids As New DataSet

    Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoad.Click
        DS_Aids.ReadXmlSchema("Study_Aid_Schema.xsd")
        DS_Aids.ReadXml("Study_Aid.xml")
        For Each Subject In DS_Aids.Tables("Subject")
            lbSubjectBox.Items.Add(Subject.ToString)
        Next Subject
 End Sub
End Class
Anyone have any idea where I am going wrong?
