Retrieves the headers for the specified message from the
server.
Syntax
object.GetHeaders( MessageNumber,
Headers )
Parameters
- MessageNumber
- Number of the message to retrieve from the server. This value
must be greater than zero. The last available message number is
returned by the LastMessage property.
- Headers
- A string or byte array which will contain the data transferred
from the server when the method returns.
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 message 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.
