New Post: Move Message to Another Folder

ramreddy — Wed, 19 Nov 2008 07:01:45 GMT

In GMail, When I am trying to move the message to another folder, through the method, MoveMessageToFolder() its not working.

when i check the implementation of that method, it's divide into 2 parts.
1. Copy message to another folder
2. Delete that Message

But irrespective of the result of the first part second part is happening.
Here i am getting problem in first part. but second part is completing successfully. that means message is deleting not moving.

and in that method CopyMessageToFolder() method, i am getting the Response from IMAP server to the following command

command : UID copy 19025 "foldername"
Response : "NO No MEssage MAtch (failure.)"

why this happening? why IMAP server not recongnizing message.
when i tried in google, in some groups, some advised, have to refresh the summary/index.
But in this case how to refresh?

            while (msgCount.Length == 0)// msgCount is null; will hit an exception :)
            {

Created Issue: CreateFolder - _client not instantiated

Darknesss — Wed, 27 Aug 2008 07:54:32 GMT

Trying to do some more advanced InterIMAP stuff, I ran into the following issue:

I create a new folder (folderX) using client.CreateFolder.

Then I want to add 2 subfolders to that but I get an error:

IMAPClient client = new IMAPClient(config, null, 5);
client.CreateFolder("FolderX");
//this fails because IMAPFolder._client is not instantiated:
client.Folders["FolderX"].CreateFolder("Processed", false);
client.Folders["FolderX"].CreateFolder("Unknown", false);

it fails because the _client property of the new folder FolderX is null while it should point to client (as fas as I could figure out)

I updated the code in IMAPClient to this and now it works for me:

public void CreateFolder(string name)
{
if (OfflineMode)
{
Log(IMAPBase.LogTypeEnum.WARN, "Cannot create folders in offline mode.");
return;
}

string cmd = "CREATE \"{0}\"\r\n";
ArrayList result = new ArrayList();
string newFolder = String.Format("{0}", name);
_imap.SendAndReceive(String.Format(cmd, newFolder), ref result);
if (result[0].ToString().Contains("OK"))
{
IMAPFolder oNewFolder = new IMAPFolder();
oNewFolder.FolderName = name;
oNewFolder.FolderPath = newFolder;
oNewFolder.ParentFolder = null;
oNewFolder.ParentFolderName = String.Empty;

//MODIFIED:
oNewFolder.SetClient(this);
//END MODIFICATION

_folders.Add(oNewFolder);
UpdateCache(true);
Log(IMAPBase.LogTypeEnum.INFO, String.Format("Folder {0} created successfully.", name));
}
else
{
_imap.Log(IMAPBase.LogTypeEnum.ERROR, "Folder could not be created (" + result[0].ToString()+")");
}

}

and in the IMAPFolder.CreateFolder version:

if (this._client != null)
oNewFolder.SetClient(this._client);

Is this a real bug or did I use the library in a way I shouldn't use it?

Darknesss — Mon, 25 Aug 2008 15:03:19 GMT

this is probably a little better:

oNewFolder.SetClient(this);

and in the IMAPFolder.CreateFolder version:

if (this._client != null)
oNewFolder.SetClient(this._client);

New Post: EML to MSG

Does your library provide support for converting eml files to msg files? Is there a work around perhaps?

Thanks!

New Post: MarkAsRead

Darknesss — Mon, 04 Aug 2008 14:55:29 GMT

made somewhat progress...

I do a search, then
IMAPMessage msg = f.GetMessageByID(id);
for each message id that was returned by the search.
I mark each message as read and that seems to work except for the last one being examined (I'm parsing the attachment).

I have the impression that I need to trigger something after that last message to make sure it gets set on the server.
This impression comes from the fact that I need to call RefreshData to make sure all attachments show up.

Any suggestion or anything I didn't see?

I am having the same issue, also with an exhange server.

I stepped through it but the command seems to succeed. However, the message is still marked unseen.

New Post: Config file encryption

Darknesss — Fri, 18 Jul 2008 08:57:10 GMT

I have just a little remark about the config files...

Would it be possible to somehow encrypt the password a little or hash it in the the configfile?

Now you can just see the password in plain text if you open such a configfile in notepad. This could be a security risk.

ctbrewski — Mon, 07 Jul 2008 21:41:20 GMT

Jason,

When I call msg.MarkAsRead() do I need to do anything else, like a refresh? For some reason, this does not seem to flag the message as seen (I am using Exchange server) and I was wondering if I was missing something.

Thanks,

Todd

Sorry, my bad.
I'm using lumisoft mail server, and new message has only unseen flag.
How can i find/count new messages?

New Post: QuickSearchNew Problem

JasonMiesionczek — Mon, 07 Jul 2008 19:51:40 GMT

the NEW term is not a flag, its a parameter to the SEARCH command that is equivalent to (RECENT UNSEEN)

See ftp://ftp.rfc-editor.org/in-notes/rfc3501.txt
Section 6.4.4 for the definition of the SEARCH command

New Post: QuickSearchNew Problem

yuri99 — Mon, 07 Jul 2008 07:14:30 GMT

Problem with public IMAPSearchResult Search(IMAPSearchQuery query)

Line: if (query.New) searchTerms.Add("NEW");

Why you use flag "NEW"?
Right IMAP Flag is "UNSEEN".
Imap flags are \Answered \Flagged \Deleted \Seen \Draft \Unseen...

New Post: Examples?

JasonMiesionczek — Tue, 01 Jul 2008 20:10:17 GMT

Hey Todd,

Check out my latest post to Haser's discussion, Checking for new messages. I checked-in an update to the source which incorporates specific functionality to check for new messages, without having to process the rest of the messages in the folder. So check out that post, and check out the new code and let me know if that is helpful to you.

Jason

New Post: Examples?

ctbrewski — Tue, 01 Jul 2008 17:59:28 GMT

Jason

Thanks for your reply. I made the changes and it looks like I am back to square one. When you run a search, the search returns a list of UIDS, which are then compared with the folder's message list, returning the found messages. This means that if you don't have the folder's messages loaded, search will not return any results, even if matches are found from the server call.

By the way, if you have AutoGetMsgID = true, it will load all messages recursively through all the folders, so I couldn't use this if I moved messages into sub-folders. You may consider changing the autoload to load the folder messages only if/when you access the folder.

The solution I will use is to change the GetSelectedFolderMessageIDs to pull UNSEEN rather than ALL messages.

One request for a future enhancement though: Add a QuickSearchUnseen() in addition to QuickSearchNew(). I added this to my code and it returns a different result than the New does (this may have something to do with how Outlook flags messages as seen/unseen).

Thanks for all your help. You've really improved the IMAP library.

In your IMAPConfig instance, if you set AutoGetMsgID = false, the msg UIDs will not be downloaded until requested.

Additionally, you can modify IMAPFolderCollection to look like this:

if (f._client.Config.AutoGetMsgID)
f.GetMessageIDs();

This will further ensure that the UIDs are not downloaded automatically. So this should enable you to connect to the server, select the desired folder, and search for new messages without having to download all the messge ids of that folder.

Question, without knowing the application that you are building, would it be possible to move opened messages to another folder once they've been processed? That could improve performance as well as there would only be new messages in the inbox.. just a thought.

New Post: Check for new messages

JasonMiesionczek — Tue, 01 Jul 2008 13:31:34 GMT

Hello,

I just checked in new code to facilitate the checking of new messages in a folder. It looks like this:

IMAPFolder f = client.Folders["INBOX"];

            int[] msgCount = null;

            while (msgCount.Length == 0)
            {
                msgCount = f.CheckForNewMessages();
                Thread.Sleep(1000);
            }

            foreach (int id in msgCount)
            {
                IMAPMessage msg = f.GetMessageByID(id);
                // do some logic here
                msg.MarkAsRead();
            }

As i mentioned in the changeset comments, the library now obeys the AutoGetMsgUIDs flag in the config, and will not automatically download all the UIDs in the selected folder. This should allow you to connect to the server, select a folder and check for new messages without the need to touch any existing messages. As the example above shows, the CheckForNewMessages returns an array of ints which are the UIDs of the new messages. To process these new messages you can use the GetMessageByID method to download them individually.

If you attempt to access the Messages collection of the folder, it will force ALL of the UIDs to be downloaded which may not be desired.

Hope this addresses the problem you were having,
Jason

Source code checked in, #11206

JasonMiesionczek — Tue, 01 Jul 2008 13:29:09 GMT

Updated CheckForNewMessages to return an array of UIDs instead of just the count. This way, once you have the array of IDs you can use the GetMessageByID method in IMAPFolder to get the data for only the new messages.
