MAPI inbox checker

rodmcleay · September 9th, 2003, 03:43 AM

I am required to create an application that will check a specified email inbox for email attachements.
This is my first adventure into C# although I have built this app in VB6 previously.
I am rebuilding it to learn C# whilst improving the app.
I am having trouble with even the most simple area of logging in the MAPI session object.
Can anyone point me in the direction of a good article of tutorial on this.
I do not wish to rely on 3rd party tools or outlook, just straight to the Exchange server.

At present I have included the session and message components which are of types AxMSMAPI.AxMAPIMessages and AxMSMAPI.AxMAPISession and have instantiated them (I Think!) with the code:

private void btnCheckMail_Click(object sender, System.EventArgs e)
        {
            MAPISession = new AxMSMAPI.AxMAPISession();
            MAPIMessages = new AxMSMAPI.AxMAPIMessages();

        }

I do not know where to go from here, any advise or redirection would be very much appreciated.

Thankyou for your time.

I have changed direction on this, solving many of my problems but creating new ones.
If you have used CDO 1.2.1 or MAPI and C# please take a look at my code below.
The purpose of the code (at ths stage) is just to list the email attachments in an inbox using their full names.
Later on I will move them arround accordingly.

Solution 1: Using the MAPI Component
This will only provide a truncated(8.3) attachment file name which does not suit my needs

Code:

label1.Text = string.Empty;
axMAPISession1.DownLoadMail = true;
axMAPISession1.SignOn();
axMAPIMessages1.SessionID = axMAPISession1.SessionID;
axMAPIMessages1.Fetch();
for ( int i=0; i< (int) axMAPIMessages1.MsgCount; i++)
{
axMAPIMessages1.MsgIndex = i;    
for (int j=0; j< (int)axMAPIMessages1.AttachmentCount; j++)
{
//List the attachment names
label1.Text += axMAPIMessages1.AttachmentName + "\n";
}            
}
axMAPISession1.SignOff();

Solution 2: Using CDO 1.2.1
This can access the full attachment filename (So I'm Told) but I am unable to get it to log in to an exchange inbox.

Code:

            MAPI.Session objSession;
            MAPI.Folder objFolder ;
            MAPI.Messages objMessageList;
            MAPI.Message objMessage;
            MAPI.Attachments objAttachmentList;
            MAPI.Attachment objAttachment;
            MAPI.MessageFilter objFilter;

            objSession = new MAPI.SessionClass();
            // Logon to the Exchange Server using Internet Mail method and profile
            objSession.Logon("MYADMINPROFILENAME", "MYADMINPASSWORD", false, false, 0, true, "MYMAILSERVER\nMYADMINPROFILENAME");

            objFolder = (MAPI.Folder) objSession.Inbox;
            objMessageList = (MAPI.Messages) objFolder.Messages;
            //Set filter to get all unread mail
            objFilter = (MAPI.MessageFilter) objMessageList.Filter;
            objFilter.Unread = true;
            objMessage = (MAPI.Message) objMessageList.GetFirst(objFilter);



            if((int) objMessageList.Count == 0)//objMessage Is Nothing
            {            
                label2.Text = "No Mail:" + System.DateTime.Now;
            }
            else //Never made it to here
            {
                //("You've got mail")
                //' Loop until all mail are read
                for (int i=0; i<(int)objMessageList.Count; i++)
                {            
                    objAttachmentList = (MAPI.Attachments) objMessage.Attachments;
                    for (int j=0; j<(int)objAttachmentList.Count; j++)
                    {
                        objAttachment = (MAPI.Attachment) objAttachmentList.get_Item(j); 
                        //label2.Text += objAttachment.Fields(CdoPR_ATTACH_LONG_FILENAME) + "\n";                    
                        label2.Text += objAttachment.Name + "\n";                    
                    }
                }

            }

I am new to c# so please point out the obvious.
I feel the main problem with the CDO 1.2.1 is the logging in.
With the MAPI Component I don't think the full file name is available, please tell me if I am wrong.

PS
No errors are occuring in the code.
It just does not do what I want it to.

Thanks for your time to read my problem
