startDocument Method
Receives notification of the beginning of a document. The reader invokes the startDocument
method only once.
The startDocument
method is invoked before any other methods in the IVBSAXContentHandler
interface or in the IVBSAXDTDHandler
interface. Only the documentLocator
property is invoked before the startDocument
method.
Implementation Syntax
Sub startDocument()
Usage Syntax
oContentHandler.startDocument
Return Values
If failed, the ContentHandler
raises a trappable error.
Example
The following example uses the startDocument
method to set the text property for a text box (Text1) on the main application form (Form1). The new text indicates that the reader has begun reading the document.
Private Sub IVBSAXContentHandler_startDocument() Form1.Text1.Text = "Starting document." & vbCrLf End Sub
The startDocument
method is invoked before any other methods in the ISAXContentHandler
interface or in the ISAXDTDHandler
interface, with the exception of the putDocumentLocator
method.

HRESULT startDocument();
