The Sample Program

Visual Basic User's Guide > XML Basics

The sample program has only one menu item, which is Open File. Looking at the source code reveals nothing unusual: The main difference to the Open File routine in other Text Control sample programs is the Load method's Format parameter. It has a value of 10 to indicate that we want to laod an XML file:

[Visual Basic 6]
With CommonDialog1
   .Filter = "*.xml"
   .Flags = cdlOFNFileMustExist Or cdlOFNHideReadOnly
   .CancelError = True
   .ShowOpen
   If .FileName <> "" Then
      TXTextControl1.Load .FileName, , 10
   End If
End With

There is quite a bit happeing behind the scenes, however. If you load the TestFile.xml sample file, Text Control will not only load the xml file, but will

• automatically validate it using the enclosed DTD, and
• format it according to the CSS stylesheet provided.

Let us take a closer look at the 3 files involved.
