More on UserProperties

[Steve]

1) I have seen other MVP's say that when a UserProperty is added the item
should be saved , can you safely add many items (like many user properties)
before actually saving the item?

2) I am working on an Outlook addin that works great on my dev machine but
appearantly doesn't save/read userproperties for appointment items but task
items appearantly read/save fine on most systems.

 

[Dmitry Streblechenko]

1.Yes, you can set any number of properties before calling Save
2. Provide the relevant snippets of your code and indicate what exactly does
not work.

Please use my comment for your product OutlookSpy: WOW! It does what it
says!

As hard as it was to articulate the differences between two systems with
your tool I think I may have found something, finally.

Dmitry although it does require some explaination - looking at the IMessage
GetProps tab I see lots of differences in number of properties with each
Appointment item and values. As I suspected my userproperties have no values
in the system/version that doesn't work. one property that is interesting is
http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/urn:schemas:calendar:version.
BTW the value is 2.0. I don't see this one on systems that do work for my
Outlook Addin. Do you know what its for?
Can you offer an explanation why aren't my properties storing values? Is it
possible my properties somehow depend on the property offset?

Ok here's what I got:

Microsoft.Office.Interop.Outlook.AppointmentItem appt;
string propertyName = "MyProp";

// if the property doesn't exist
if(!appt.UserProperties.Find(propertyName,Type.Missing))
{

appt.UserProperties.Add(propertyName,Microsoft.Office.Interop.Outlook.OlUserPropertyType.olText, Type.Missing, Type.Missing);
}
appt.UserProperties[propertyName].Value = value;
appt.Save();

Steve

 

[Dmitry Streblechenko]

Try the following instead:

UserProperty prop = appt.UserProperties.Find(propertyName,Type.Missing);
if (prop == null) prop = appt.UserProperties.Add(propertyName,
OlUserPropertyType.olText, Type.Missing, Type.Missing);
prop.Value = value;
appt.Save;

Thank you for the reply unfortunately it still doesn't work on all machines.
However the changes didn't break anything on previously working machines.
First let me apologize for double posting Ken Slovak politely yelled at me
for also posting in the VSTO newsgroup. Ken my apologies. Dmitry - I
noticed your app which works perfectly well on several machines I'm working
with for testing uses a different interface. Some sample code also on
outlookcode.com by Helmut Obertanner that was inspired by yourself that
doesn't use the Outlook Object Model. Is this another potentially better
more generic approach?

That's exactly what I see on machines that my addin is running but is unable
to set and retrieve property values on. OutlookSpy shows empty properties
with the right name but no value when I click IMessage. On other machines
my code works great, it sets and retrieves properties using the code you

I have saved the IMessage to text files via OutlookSpy. I can provide them

There is nothing special about the machines where the get/set property
methods not appearantly work. The items are in the primary mailbox store
under the calendar folder these are appointment items. My app also works
with task items in the primary mailbox store. The get/set methods of the OOM
appearantly work on task items even when the same code fails on calendar
items. The machines are just running patched up-to-date XP with Office 2k3
Professional sp3. Outlook is running in an exchange env with Exchange Server
2k3. My test env involves my physical notebook running the same as above and
a development vm running Server 2k3 patched with Office 2k3 Pro sp3 and
vs.net 2003 with install shield. Outlook in the vm is also running connected
to exchange 2k3. This is why I don't understand the differences in the
number of properties for each calendar item between machines.

2. Provide the relevant snippets of your code and indicate
what
exactly
does
not work.

1) I have seen other MVP's say that when a UserProperty is
added
the
item
should be saved , can you safely add many items (like many
user
properties)
before actually saving the item?

2) I am working on an Outlook addin that works great on my
dev
machine
but
appearantly doesn't save/read userproperties for
appointment
items
but
task
items appearantly read/save fine on most systems.

 

[Steve]

Yes. And the script works just fine. I viewed the IMessage afterwards and
the property test is there with its value of whatever

Can you edit these properties form OutlookSpy?
Can you run the following code from OutlookSpy (click Script Editor button
when the item in question is selected)?

set Item = Application.ActiveExplorer.Selection(1)
set prop = Item.UserProperties.Find("test")
if (prop Is Nothing) Then
set prop = Item.UserProperties.Add("test", olText)
End If
prop.Value = "whatever"
Item.Save

There is nothing special about the machines where the get/set property
methods not appearantly work. The items are in the primary mailbox store
under the calendar folder these are appointment items. My app also works
with task items in the primary mailbox store. The get/set methods of the
OOM
appearantly work on task items even when the same code fails on calendar
items. The machines are just running patched up-to-date XP with Office
2k3
Professional sp3. Outlook is running in an exchange env with Exchange
Server
2k3. My test env involves my physical notebook running the same as above
and
a development vm running Server 2k3 patched with Office 2k3 Pro sp3 and
vs.net 2003 with install shield. Outlook in the vm is also running
connected
to exchange 2k3. This is why I don't understand the differences in the
number of properties for each calendar item between machines.

Any there anythign special about thee machines where the code does nto
work?
Where does tehe item come from? Is it is primary mailbox store, delegated
store, Public Folder, etc?

That's exactly what I see on machines that my addin is running but is
unable
to set and retrieve property values on. OutlookSpy shows empty
properties
with the right name but no value when I click IMessage. On other
machines
my code works great, it sets and retrieves properties using the code
you
suggested just as well as it did before with the code I submitted
previously.
I have saved the IMessage to text files via OutlookSpy. I can provide
them
if you think it would be helpful. Did I say I appreciate the help, I
do.

So what exactly happens when you run that code? Do you see an empty
property
with the right name but no value in OutlookSpy when you click
IMessage?

Thank you for the reply unfortunately it still doesn't work on all
machines.
However the changes didn't break anything on previously working
machines.
First let me apologize for double posting Ken Slovak politely yelled
at
me
for also posting in the VSTO newsgroup. Ken my apologies. Dmitry -
I
noticed your app which works perfectly well on several machines I'm
working
with for testing uses a different interface. Some sample code also
on
outlookcode.com by Helmut Obertanner that was inspired by yourself
that
doesn't use the Outlook Object Model. Is this another potentially
better
more generic approach?

Thanks
Steve

Try the following instead:

UserProperty prop =
appt.UserProperties.Find(propertyName,Type.Missing);
if (prop == null) prop = appt.UserProperties.Add(propertyName,
OlUserPropertyType.olText, Type.Missing, Type.Missing);
prop.Value = value;
appt.Save;

Ok here's what I got:

Microsoft.Office.Interop.Outlook.AppointmentItem appt;
string propertyName = "MyProp";

// if the property doesn't exist
if(!appt.UserProperties.Find(propertyName,Type.Missing))
{

appt.UserProperties.Add(propertyName,Microsoft.Office.Interop.Outlook.OlUserPropertyType.olText,
Type.Missing, Type.Missing);
}
appt.UserProperties[propertyName].Value = value;
appt.Save();

What is your code that sets the propeties and saves the item?

Dmitry
Please use my comment for your product OutlookSpy: WOW! It
does
what
it
says!

As hard as it was to articulate the differences between two
systems
with
your tool I think I may have found something, finally.

Dmitry although it does require some explaination - looking at
the
IMessage
GetProps tab I see lots of differences in number of properties
with
each
Appointment item and values. As I suspected my userproperties
have
no
values
in the system/version that doesn't work. one property that is
interesting
is
http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/urn:schemas:calendar:version.
BTW the value is 2.0. I don't see this one on systems that do
work
for
my
Outlook Addin. Do you know what its for?
Can you offer an explanation why aren't my properties storing
values?
Is
it
possible my properties somehow depend on the property offset?

I just realized an oddity on the test machine: Office Communicator 2007 is
installed with Live Communication Server 2007. So I thought I would perform
a detect and repair for the heck of it removing all customization returning
to default settings... It resolved the get/set property problem using the
OOM. But this doesn't explain why. Undoubtly I will have to supoprt systems
without modification. I assume I'll have to use MAPI or extended MAPI in a
mixed 2003/2007 env.

Thoughts?
