EntryID

[Matt]

Hi,

Does anyone have details on the EntryID value for a Task. I need a unique
number for every task. EntryID gives it to me, but it is a very long hex
string. Anyone have a hash function that gives me a unique but more
reasonable number from it? Alternately another way to generate a unique
number would be appreciated.

Thanks,

Matt

EntryID is unique, but not necessarily persistent. If the item is
moved to a different folder or different InfoStore the EntryID
changes.

I usually use a CDO method of the Session object,
Session.CreateConversationIndex to create GUID's in my Outlook code,
but they are also long and you have to have CDO installed for that.
Using the Windows API you can use CoCreateGUID to create a unique tag
but that is also long. How about just getting the time and date and
making that a GUID string?

Hi Ken,

Thanks for the response. What I have done is create a task for filling an
order. I want to be able to provide an order number to the customer and
have focused on EntryID because Outlook ensures it uniqueness. Time and
Date will run me into concurrency problems (two people pressing submit at
the same instance). I can't be the only one wanting this so am I doing
something wrong?

Thanks,

Matt

In a small office, appending the user's initials should get around the
concurrency issue.

You can do as Sue suggests and use the initials appended to the
date/time or use one of my other suggestions. It's not at all unusual,
but EntryID is not the best thing to use since it may change for an
item.

Hi Ken and Sue,

I think between the two of you I am heading for a solution. Sue how would I
retrieve the initials? CurrentUser seems to be dependent on how the user
setup their preferences. Also is possible to extend CurrentUser? That
would solve alot of problems for me.

Thanks,

Matt

Depends. If you're using Exchange, I'd walk up the folder tree to the
mailbox root and get the name from there. (CurrentUser triggers security
prompts.)

Here's a VBA snippet that gets it from an environment variable:

Function WSHUserName() As String

Set objWSHShell = CreateObject("WScript.Shell")

WSHUserName = _

objWSHShell.ExpandEnvironmentStrings("%username%")

Set objWSHShell = Nothing

End Function
