setting 'AllDayEvent' causes an exception ?

[Mark Beiley]

I have an add-in that is modifying the properties of a calendar event. When
it gets here:

olAppt->AllDayEvent = 0;

Outlook is throwing an exception. This code works fine on most events, but
on some events this will fail. Any ideas why this would fail? Is there
some other property I need to make sure to set first or something?

Thanks,
Mark

And what is the exact error message?

Hi Dmitry,

I don't see any error message... I have this in a try/catch block and
Outlook throws an exception when I try and set AllDayEvent. My code looks
like this:

try
{
olAppt->AllDayEvent = 0;
}
catch(...)
{
// do some error logging...
}

I'm writing my add-in in C++. Is there some way I can get some sort of
error message from Outlook? I really have no indication of 'why' it is
failing, I just know where it fails.


Thanks,
Mark

Do you log the exception details in your catch() block? Does the error get
raised immediately or only after you process a few items? Where does olAppt
come from? Are you sure it is an AppointmentItem object and not something
else?

Hi Dmitry,

I don't log any exception details in the catch block. Honestly, I'm not
sure how, but I can probably research it and figure out how. What sort of
details are available that would be helpful for logging in the catch block?
Do you know if there is some error message or code set somewhere when
Outlook throws an exception?

It gets raised immediately. I only have this one line of code in the try
block.

I'm pretty sure the olAppt is valid and an appointment item. I'm
enumerating through items in the calendar folder. I successfully use it
right before this to set other properties like Body and Location.


Thanks,
Mark

Hi Dmitry,

I found a class '_com_error', which will capture information thrown
by Outlook. It has both an error number and a description.

I've added this into my catch block, and hopefully this will give more
information on what the problem is. (I have to wait for my customer who is
experiencing this problem, I can't reproduce it here...)
I'll post the results once I get them.

Thanks,

information on what the problem is. (I have to wait for my customer who

experiencing this problem, I can't reproduce it here...)
I'll post the results once I get them.

That error message will include the phrase, "invalid property assignment."

Assigning the AllDayEvent property will throw an error if a recurrence
pattern has been defined for the AppointmentItem, you can test the
IsRecurring property to check for this. (The same applies to the Start and
End properties, assignments to them are invalid if the item is recurring.)

Correspondingly, the AllDayEvent flag is ignored for recurring items, the
duration is set for 24 hours, but the event starts (according to Outlook) at
midnight in the system-configured time zone, when recurrence is defined.
Example: while living on the east coast, you create a recurrent event for
your wife's birthday; you then move to the west coast, and change your
system's time zone accordingly; the event for your wife's birthday now
starts at 9:00 PM on the day prior.

Conversely, a non-recurring item flagged as as AllDayEvent starts at
midnight in the system's time zone, no matter what that time zone is, and it
does not change if the timezone changes.

(Technically, the underlying value [stored as UTC] does not change for
recurrent items, it's just the displayed value that adjusts. For
non-recurring AllDayEvents, Outlook *might* actually change the underlying
UTC value to adjust it to display as midnight in the new time zone, but if
it does, it does so without changing LastModificationTime. I'd have to go
underneath OOM, and read the value [before and after changing time zones]
using Redemption to know for sure... too lazy to do that at the moment.)

When trying to set the AllDayEvent to 0, Outlook throws this exception:

Exception 0xc6204005 from Microsoft Office Outlook
Error Desc: You don't have the permission to move this item.

They are using a local .pst file, so they should have permission. The error
always seems to happen on the same specific event. Any ideas?

Are you really trying to change AllDayEvent for an instance of a recurring
activity, not the master appointment??

Hi Dmitry,

This should be either a master or non-recurring appointment. I will add
some code in my catch block to query 'RecurrenceState' to make sure. I'll

Hi Mark,

No, I haven't tested IsRecurring. Is there some required relationship
between this and AllDayEvent? I am under the impression that you can set
AllDayEvent on either a one time or a recurring master appointment...

Check the value of the RecurrenceState property, and if it is
olApptOccurrence or olApptException, use the master appointment instead
(will be returned by AppointmentItem.Parent)

(Technically, the underlying value [stored as UTC] does not change for
recurrent items, it's just the displayed value that adjusts. For
non-recurring AllDayEvents, Outlook *might* actually change the
underlying UTC value to adjust it to display as midnight in the new
time zone, but if it does, it does so without changing
LastModificationTime. I'd have to go underneath OOM, and read the value
[before and after changing time zones] using Redemption to know for
sure... too lazy to do that at the moment.)

Hi Dmitry,

I don't log any exception details in the catch block. Honestly, I'm
not
sure how, but I can probably research it and figure out how. What
sort of
details are available that would be helpful for logging in the catch
block? Do you know if there is some error message or code set
somewhere
when Outlook throws an exception?

It gets raised immediately. I only have this one line of code in the
try
block.

I'm pretty sure the olAppt is valid and an appointment item. I'm
enumerating through items in the calendar folder. I successfully use
it
right before this to set other properties like Body and Location.

Do you log the exception details in your catch() block? Does the
error
get raised immediately or only after you process a few items? Where
does
olAppt come from? Are you sure it is an AppointmentItem object and
not
something else?

Hi Dmitry,

The RecurrenceState property is: olApptMaster (1).

The other Mark gave me a good tip, in that I believe it has to do with being
a recurring appointment. It seems you cannot set AllDayEvent/Start/End on
an appointment that is recurring. Instead, you must set StartTime/EndTime
on the recurrence pattern of that appointment. This seems to have fixed my
problem. Does that seem right?

Thanks,
Mark

Check the value of the RecurrenceState property, and if it is
olApptOccurrence or olApptException, use the master appointment instead
(will be returned by AppointmentItem.Parent)

Hi Dmitry,

This should be either a master or non-recurring appointment. I will add
some code in my catch block to query 'RecurrenceState' to make sure.
I'll post the results once I get them (I have to wait for my customer to
reproduce this for me...).

Hi Dmitry,

I found a class '_com_error', which will capture information thrown
by Outlook. It has both an error number and a description.

I've added this into my catch block, and hopefully this will give
more
information on what the problem is. (I have to wait for my customer
who is
experiencing this problem, I can't reproduce it here...)
I'll post the results once I get them.

That error message will include the phrase, "invalid property
assignment."

Assigning the AllDayEvent property will throw an error if a recurrence
pattern has been defined for the AppointmentItem, you can test the
IsRecurring property to check for this. (The same applies to the
Start and End properties, assignments to them are invalid if the item
is recurring.)

Correspondingly, the AllDayEvent flag is ignored for recurring items,
the duration is set for 24 hours, but the event starts (according to
Outlook) at midnight in the system-configured time zone, when
recurrence is defined. Example: while living on the east coast, you
create a recurrent event for your wife's birthday; you then move to
the west coast, and change your system's time zone accordingly; the
event for your wife's birthday now starts at 9:00 PM on the day prior.

Conversely, a non-recurring item flagged as as AllDayEvent starts at
midnight in the system's time zone, no matter what that time zone is,
and it does not change if the timezone changes.
