Retrieves the headers for the specified article from the
server.
Syntax
object.GetHeaders( Article, Headers )
Parameters
- Article
- Number of article to retrieve from the server, or a string that
specifies the message ID of the article header to retrieve. If an
article number is specified, this value must be greater than zero.
The first available article in the newsgroup can be determined by
checking the value of the FirstArticle property. The last
available article in the newsgroup is returned by the
LastArticle property.
- Headers
- A string or byte array which will contain the data transferred
from the server when the method returns. This parameter must be
passed by reference.
Return Value
A value of zero is returned if the method succeeds.
Otherwise, a non-zero error code is returned which indicates the
cause of the failure.
Remarks
The GetHeaders method is used to retrieve an article header
block from the server and copy it into a local buffer. This method
will cause the current thread to block until the article transfer
completes, a timeout occurs or the transfer is canceled. During the
transfer, the OnProgress event will fire periodically,
enabling the application to update any user interface objects such as
a progress bar.
