CNntpClient::GetNextGroup Method  
 
BOOL GetNextGroup(
  LPNEWSGROUP lpGroup  
);
BOOL GetNextGroup(
  LPNEWSGROUPEX lpGroup  
);

The GetNextGroup method returns information about the next available newsgroup.

Parameters

lpGroup
A pointer to a NEWSGROUP or NEWSGROUPEX structure which will contain information about the next available newsgroup. If the server can potentially return very large article IDs, it is recommended that you use the NEWSGROUPEX structure.

Return Value

If the method succeeds, the return value is non-zero. If there are no more newsgroups available, or the method fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

The GetNextGroup method returns information about the next newsgroup on the server. This method is used in conjunction with the GetFirstGroup method to enumerate all of the available newsgroups. Typically this is used to provide the user with a list of newsgroups to select.

While the the newsgroups are being listed, the client cannot select a newsgroup or retrieve the contents of a specific article. The client should store those newsgroups which it wants to retrieve articles from, and then once all of the newsgroups have been listed, it can then select each newsgroup and retrieve the available articles from that group.

Example

// List all available newsgroups
if (pClient->ListGroups() == NNTP_ERROR)
    pClient->ShowError();
else
{
    NEWSGROUP newsGroup;
    BOOL bResult;

    // Get each newsgroup, printing the article range and
    // the name of the group
    bResult = pClient->GetFirstGroup(&newsGroup);
    while (bResult)
    {
        printf("%ld %ld %s\n", newsGroup.nFirstArticle,
                               newsGroup.nLastArticle,
                               newsGroup.szName);
        bResult = pClient->GetNextGroup(&newsGroup);
    }
}
