Remove a meeting in lotus notes using Visual Basic code
I am trying to create an application that will remove a meeting from the calendar in Lotus Notes. So far i managed to write the code for the creation of the meeting but not the removal part,would appreciate if someone can help me. The code i used to create the meeting is this :
Private Sub Meeting(ByVal reser_type As String, ByVal reser_id As String, ByVal reser_by_mail As String, ByVal reser_by_name As String, ByVal usr_mail As String, ByVal usr_name As String, ByVal tb_op_mail As String, ByVal tb_op_name As String, ByVal tb_n As String, ByVal tb_r As String, ByVal reser_start As String, ByVal reser_end As String, ByVal project As String, ByVal req_project_cnf As String, ByVal reser_req_conf As String, ByVal tb_dec_n As String, ByVal stat As String, ByVal erase_in_file As String, ByVal com As String)

How do you intend to identify the meeting?
And then there was silence... Ok, I'll explain my question. To be able to delete a meeting, you have to identify it, in order to grab it in the database or a view, and then delete it. Usually, it is not correct to delete someone's meeting. It would be better to send the person a message that the meeting is cancelled. To do that, you need to adhere to the meeting planning protocol.

sorry about that,i was out of the office and i just got back,i don't actually know how to identify it i was just asked to create an application that deletes a meeting,similar to the code i wrote above.
Then you're missing some specifications, I'd say... Is it a function or subroutine they require, is it an interactive process, or what exactly do they want?
ASKER
it wasn't specified,when i asked they told me they need only the application ,as far as i understood they want to cancel appointments since the program i designed already does that
"Write a book and store it". That's doable.
They: "Remove a book".
You: "Any book?".
They: "No, a specific one".
You: "Ah, then I need to know which one?"
Seems logical to me...
In any case, you'll need to identify a Meeting, i.e. a Notes document in the user's mail database. What do you know about it? Date/time/place? Maybe its name? Or did you leave some id when you created the meeting? Do you also have to remove meetings your application didn't create, i.e. one of those created by the user?

ASKER
Yes,i should be able to remove meetings the application didn't make based on a given subject,start time and end time
Ah, subject, start time, end time... Good! But is that enough? Probably it is, in 99.5% of all cases, but should you be prepared also for meetings that were altered by the user in any way, which would make it impossible to find the meeting? Hence my question: when you created the meeting, did you leave some unique key in it that you store in your own database somewhere, which would make identification a 100% certainty?
Okay, finding back a meeting based on start time shouldn't be that hard. Basically it requires you to open the Calendar view and search the view based on the start time. In LotusScript:
Dim view As NotesView
Set view= db.GetView("Calendar")
Dim keys(0) as Variant
Dim keydate As NotesDateTime
Set keydate = New NotesDateTime("01/15/2000 13:30:00")
Set keys(0) = keydate
Dim doc as NotesDocument
Set doc= view.GetDocumentByKey(keys
There could be multiple events at the same time. Check the Subject, or if you have it, the unique key you stored in it.

ASKER
Thank you, i will look it up
ASKER
I tried to use the code that you provided but i get a COM cast error and can't figure it out
I assume you have to declare every object as Object, instead of NotesXxxx. Plus, in VB there is no New NotesDateTime, that has to be session.CreateDateTime.
Could you give that a try?
Could you give that a try?
ASKER
yeah,i did it already but the doc is always empty even though i have the meeting in my calendar set up with the proper hours
What's your current code; the part that searches the meeting document?
Can you run it in debugging mode? I assume doc is Nothing, which means that the document isn't found.

And does your document have a field names CalendarDateTime? That field is indispensable, it should be set the same as StartDateTime.
ASKER
By document do you mean the meeting or? Sorry i'm quite new to Lotus just started using it 1-2 weeks ago.

ASKER
Yes,it's type 3 (Meeting)
And the item CalendarDateTime? If there is one, what type is it?
ASKER
There isn't one, there is only start date where you type the hour,local time and date

I checked and both CalendarDateTime and StartDateTime have the same type and the same hour stored

Then, according to all theory, you should be able to find the meeting document. Let me do some tests here, to see if I can find a meeting using the Calendar view. I'll be back... ;-)
Ah yes, the meeting still exists because the Remove only moves it to the Trash folder, when activated. Good that you found the missing element!
Just a warning: watch out when you search for a meeting that's supposed to have a start time of 1600 but was rescheduled somehow to 1700 and a new meeting was scheduled at 1600. The date/time key is not enough and also not necessarily unique, so better do some checks!

Suits me fine, thanks!
