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 NextIf IsEof = True ThenErr.Raise vbObject + 1, "CD Information", "End of cursor"Exit SubEnd IfId = 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.MoveNextEnd 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;
