Get Flag's value

Hi

I'm using C#. And I haven't found method message.Flag(). There are message.get_flag() & message.set_flag().
They work fine. there is another problem:
I'm try to flagged unread messages:

Code:

Message mes = accountHelper.Messages.get_ItemByDBID(Id);
            bool b = mes.get_Flag(eMessageFlag.eMFSeen);
            if (hasSeen && !b)
            {
                mes.set_Flag(eMessageFlag.eMFSeen, hasSeen);
                mes.Save();
            }

This also works fine, I check it in DB and when call Messages.get_ItemByDBID(Id) it shows correct data.
But when I call accountHelper.IMAPFolders.get_ItemByDBID(folderId).Messages, changes that I've done before, hadn't considered I mean mes.set_Flag (other datas are correct). After restarting computer, accountHelper.IMAPFolders.get_ItemByDBID(folderId).Messages get datas from DB. But again after changing message's flag Messages.get_ItemByDBID(Id) get changed data and accountHelper.IMAPFolders.get_ItemByDBID(folderId) doesn't see the changes.
Why?

Thanks. Sorry for English

After restarting hMailServer accountHelper.IMAPFolders.get_ItemByDBID(folderId).Messages see the changes. Also make message.RefreshContent(), but it doesn't give results.

Did you message.save first?

Thanks for reply!
In code that I post I have mes.Save()
or what do you mean?

mes.set_Flag(eMessageFlag.eMFSeen, hasSeen); works fine I check it in DB.
And if call after setting flag this code
Message mes = accountHelper.Messages.get_ItemByDBID(Id);
bool b = mes.get_Flag(eMessageFlag.eMFSeen);
the result b=true.
But if I call
Messages msgs = accountHelper.IMAPFolders.get_ItemByDBID(folderId).Messages
bool b = msgs[index].get_Flag(eMessageFlag.eMFSeen);
the result b=false.
But in debugger I see that msgs[index]=mes.ID

I've wrote also this code

Code:

            row.ID = message.ID;
            row.HasSeen = message.get_Flag(eMessageFlag.eMFSeen);
            bool b = this.accountHelper.Messages.get_ItemByDBID(message.ID).get_Flag(eMessageFlag.eMFSeen);

And there is a case then row.HasSeen != b, but as you can see they must have equal values.

message is one of return messages of code
accountHelper.IMAPFolders.get_ItemByDBID(folderId).Messages

Can you post the whole script and detail what exactly you are trying to do please...

I suspect that you aren't properly selecting the correct IMAP sub-folder

I want to count unread messages.
If I've open unread message, executes this code

Code:

public MailDataSet.MailDataSet GetMessageById(int Id, bool hasSeen)
        {
            
            Message mes = accountHelper.Messages.get_ItemByDBID(Id);
            bool b = mes.get_Flag(eMessageFlag.eMFSeen);
            //if opened unread message
            if (hasSeen && !b)
            {
                //set flag. It realy set I check its in DB
                mes.set_Flag(eMessageFlag.eMFSeen, hasSeen);
                mes.Save();
            }
            return Converter.ToMessageDataTable(accountHelper.Messages.get_ItemByDBID(Id), this._attachmentPath);
        }

ToMessageDataTable - converts messages/message to my typedDataSet
After I need to get messages from INBOX folder(I have only INBOX, SENT, DELETED, SPAM folder, no subfolders)

Code:

public MailDataSet.MailDataSet GetMessagesByIMAPFolder(int folderId)
        {
            return ToMessageDataTable(accountHelper.IMAPFolders.get_ItemByDBID(folderId).Messages);
        }

//copy all properties from message to MailDataSet.MailDataSet.MessageRow row
public  MailDataSet.MailDataSet.MessageRow ToMessageRow(Message message,         MailDataSet.MailDataSet.MessageRow row)
        {
            
            //here copy props. don't show all because it doesn't matter
            row.ID = message.ID;
            row.HasSeen = message.get_Flag(eMessageFlag.eMFSeen);         
            bool b = this.accountHelper.Messages.get_ItemByDBID(message.ID).get_Flag(eMessageFlag.eMFSeen);
            //here in case when it's before updated message b=true, row.HasSeen = false;
            //In DB mesageflag = 1;
            row.Headers = message.Headers.ToString();
            row.HTMLBody = message.HTMLBody;
            row.FromAddress = message.FromAddress;
            row.To = message.To;
            return row;
        }

        public  MailDataSet.MailDataSet ToMessageDataTable(Messages messages)
        {
            MailDataSet.MailDataSet dataSet = new MailDataSet.MailDataSet();
            MailDataSet.MailDataSet.MessageDataTable tbl = dataSet.Message;
            for (int i = 0; i < messages.Count; i++)
            {
                //just add new row
                tbl.AddMessageRow(ToMessageRow(messages[i], tbl.NewMessageRow()));
            }
            return dataSet;
        }

I don't understand why I get difference values from identic messages?
I check it every time after setting flag.
After restarting hMailServer, I get identical values in both cases. But after setting flag situation repeated

When accessing messages, you must use the Messages property of the IMAPFolder object to do so.

The Messages property on the Account object returns a raw list of messages from the database. Changing the items in this list doesn't affect the in-memory cache which the IMAPFolder.Messages property works against.

Thanks greate for reply.

If I understand you, I should write something like this

Code:

IMAPFolder folder = accountHelper.IMAPFolders.get_ItemByDBID(folderId);
return ToMessageDataTable(folder.Messages);

not

Code:

return ToMessageDataTable(accountHelper.IMAPFolders.get_ItemByDBID(folderId).Messages);

but this changes didn't change the situation. It still returns wrong datas

What's the difference between those two, except for you using a variable? I don't see those two would be any different.

In your old code, you used

Code:

accountHelper.Messages

es.get_ItemByDBID(Id);
when you should use

Code:

accountHelper.IMAPFolders.get_ItemByDBID(folderId).Messages
