手把手教你使用VB来创建ASP组件(5) 

5、 IsEof方法

IsEof方法是用来判断是否还有更多的信息

其代码如下

Private Function IsEof() As Boolean

IsEof = RecordSetCD.EOF

End Function

6、 NextCD 方法

NextCD方法的目的是返回当前的CD信息，并将记录集的指针向下移动，这可以通过MoveNext方法和IsEof配合使用来实现

Private Sub NextCD(Id As Variant, Name As Variant, Author As Variant, Price As Variant, Information As Variant)

On Error Resume Next

If IsEof = True Then

Err.Raise vbObject + 1, "CD Information", "End of cursor"

Exit Sub

End If

Id = RecordSetCD.Fields("CD_ID")

Name = RecordSetCD.Fields("CD_Name")

Author = RecordSetCD.Fields("CD_Author")

Price = RecordSetCD.Fields("CD_Price")

Information = RecordSetCD.Fields("CD_Information")

RecordSetCD.MoveNext

End Sub

好，我们已经编写好了组件，把它们编译成CD.dll后，你最好把他们注册一下 方法是在DOS界面下，输入regsvr32 CD.dll
