Re: Problem with MAPISendMail without outlook running

11-Jan-09 23:31

I've just looked at (and run) some MAPI wrapper code that I wrote several years ago. I found the following differences:

I call OleInitialize and MapiInitialize before opening a session
I opened my session with MapiLogonEx, using these flags: MAPI_NO_MAIL|MAPI_EXTENDED|MAPI_USE_DEFAULT|MAPI_ALLOW_OTHERS. I don't use MAPISendMail either - I construct the message in my Exchange Server outbox and send it from there using IMessage::SubmitMessage. It works with or without Outlook running.
I added your MAPILogon and MAPISendMail code and added message creation - that worked fine with or without Outlook running.

So, to summarise - I presume you're calling the relevant initialisation functions?

PS - what status code is returned from MAPILogon and MAPISendMail? These could help diagnose your problem.

Hi Stuart Dootson,

Thanks for the immediate response.

I am sorry that I forgot to mention the return values.
Both "MAPILogon" and "MAPISendMail" calls returns SUCCESS_SUCCESS.

I am not getting where is the problem!

Could you please expalin in detail the code snippet which is working for you with my functions as well?

Thanks and regards,
KJ

Hi Stuart Dootson,

I even tried using the initialization calls you mentioned as below, but still the result is same.

LPMAPIINITIALIZE lpfnMAPIInitialize;
lpfnMAPIInitialize = (LPMAPIINITIALIZE) GetProcAddress (hlibMAPI, "MAPIInitialize");

MAPIINIT_0 mapiInitObj;
mapiInitObj.ulVersion = MAPI_INIT_VERSION;
mapiInitObj.ulFlags = MAPI_MULTITHREAD_NOTIFICATIONS;

if(OleInitialize(NULL) == S_OK)
MessageBox("SUCCESS", "OleInitialize");

if(lpfnMAPIInitialize(&mapiInitObj) == S_OK );
MessageBox("SUCCESS", "MAPIInitialize");

All the function returns success but the mail is not getting sent.
Please help me.

Thanks,
KJ

Here's the code I've used (note - I've #included mapi.h before this) - obviously, my e-mail address isn't "my e-mail address". This works whether Outlook is running or not. If Outlook isn't running, I get a dialog that prompts me to choose the Outlook profile to use.

This would seem to be because the MAPILogon returns MAPI_E_LOGON_FAILURE whether or not Outlook is running when MAPI_NEW_SESSION is set. This is because a) when Outlook is running, it can't create a new session, and b) when Outlook isn't running, it doesn't know what profile to open (I have no default profile). The MAPISendMail will logon, as the flags allow it to display the logon UI.

Changing the MAPILogon flag to MAPI_LOGON_UI allows the logon UI to be displayed and so we can logon if Outlook isn't running. ANd if Outlook is running, we can logon because we've said we're willing to share an existing session.

Hi Stuart,

Thanks for the suggestions.

I tried using the exact way what you have done, but still the same problem occurs. After running this code, if I open my outlook, all the mails will be held in the outbox and will get sent only when I do Send/Receive in outlook window.

Could you please suggest any more ideas on this?

Can you explain how is your original code that doesn't make use of MAPISendMail function, but you are constructing the message in the Exchange Server outbox and send it from there using IMessage::SubmitMessage?

Thanks and regards,
KJ

Re: Problem with MAPISendMail without outlook running

The rough procedure is this:

Open a MAPI session with MAPILogonEx and get an IMAPISession interface pointer
Open your message store with IMAPISession::GetMsgStoresTable and then IMAPISession::OpenMsgStore. This gets you an IMsgStore interface pointer.
Open your address book with IMAPISession::OpenAddressBook. This gets you an IAddrBook interface pointer.
Open your outbox with IMsgStore::OpenEntry to get an IMAPIFolder pointer on your Outbox.
Create the new message with IMAPIFolder::CreateMessage. This returns an IMessage interface pointer.
Set the message attributes:
- IMessage::ModifyRecipients to add recipients
- The message body is either RTF (complex) or plain text (easy). For plain text, set the PR_BODY_W property of the message
- Set the 'Sent Items' folder for the message by setting the message's PR_SENTMAIL_ENTRYID property
- Set the message's subject by setting the PR_SUBJECT_W property
- Set the message type by setting the PR_MESSAGE_CLASS_W to the correct string (I used "IPM.Note")
Send the message with IMessage::SubmitMessage
Then release all the interface pointers correctly

Hi Stuart Dootson,

I am really new to MAPI functions. I am trying to use the interface functions you suggested, but facing some difficulty in using them. Is it possible to put your source code here so that I can better understand how to use those functions and succeed.

Thanks and regards,
KJ

Can I suggest you download the Microsoft MFCMAPI[^] sample - that's got pretty much all the code that I mentioned and it's publicly available - I don't think my employers would be too happy if I were to post some of our application code Blush | :O

cPtr = (unsigned char *) &Float1 ;
cPtr += 3;
for (k = 0; k<=4; 4; k++)
{
*cPtr = sBuffer [BufPtr++];
cPtr--;
}

What the equivalent of pointer and address in C++ and C#. How to convert above code into C#?
Thanks

Hi,

pointers are available in C# although you often don't need them.

When used, you will need to turn on the "allow unsafe code" switch of the compiler,
and the "unsafe" keyword, possibly the "fixed" keyword too. I suggest you read up on those
if you can't live without pointers.

[C] IRC client check if he is still operative

ogn0s11-Jan-09 10:59

11-Jan-09 10:59

Hello,
I have written irc client. He stays on server because he answers to PING from server. But... when IRC server is reboot'ed or internet connection is disconected client can't see this happen and is inoperative till client is restarted again.

I want make some detection from client side to check if client is still online or IRC server died/client internet connection died.

How to do this simpliest way?

Help,
Regards

If you don't receive any pings from the server anymore for 5 minutes, it is probably gone.

11-Jan-09 13:11

Yes i was thinking about it but wasnt sure if it is good solution, thanks a lot for answer.

So maybe like this:

DWORD timestamp = GetTickCount();

then in endless loop

if (timestamp < (GetTickCount() - 300000) ){
main(); //restart
}

if (Ping){
answer_pong;
timestamp = GetTickCount();
}

Hope it will work Smile | :)

thanks again

ogn0s11-Jan-09 13:35

11-Jan-09 13:35

yup it works good Smile | :)

ping freq on ircd is 90 sec. so im checking now 110 sec. if client should reconnect.

Im curious how doing it mIRC client because its instant after disconnect from ircd but it isn't known by client ( ircd dont send any message ).
If they use same method as we above, optimally it would be 91 sec. between disconnect and reconnect but its instant.

Well, if the server (or maybe someone inbetween, like a proxy or such) closes the connection the TCP way (like, the server (the ircd) gets shut down normally), your client will know "rightaway" that the other side is "gone", however, if there is for example a power outage and the server just disappears all of a sudden without a word, your client can't know what happened, it can only guess that since the server doesn't say anything for a while, it's probably gone.
This is probably what happens when there is a split and what you see is that for a while, noone seems to answer you anymore, and after a few minutes you get the flood of people quitting. Something happens between two irc servers and they can't talk to each other anymore, and after a while they consider each other to be gone and generate the split event.
