Add Outlook task item

I am using ms outlook 2003. I want my application to create outlook tasks automatically, based on the dates in my database and assign tasks to contact in my contacts folder. How can I achieve this?

Thanks

Adding the task request is a pretty simple deal, eg (include ComObj, ActiveX in uses):

var  ovOutlook:     OleVariant;
     ovItem:        OleVariant;
begin

  ovOutlook:=CreateOleObject('Outlook.Application');
  try
     ovItem:=ovOutlook.CreateItem(3);
     try
        ovItem.Recipients.Add('foo@bar.net');
        ovItem.Subject:='Prepare Agenda For Meeting';
        ovItem.DueDate:='7/22/2006';
        ovItem.Assign;
        ovItem.Send;
     finally
        ovItem:=Unassigned;
     end;
  finally
     ovOutlook.Quit;
     ovOutlook:=Unassigned;
  end;

end;

The problem comes from Outlooks security model kicking in. As soon as you set do anything related to emailing (and no UI is being displayed), then Outlook kicks up dialogs to the user indicating that a script is trying to automate such and such. If your ok with that, then the task should be straightforward.

If this isn't ok, I can tell you what needs to be done, but without all the tools (difficult to come by) it will be a headache.

- If an application has been digitally signed (even self signed), then Outlook can import the certificate, allowing the application to automate Outlook without the security warnings. In the "C:\Program Files\Microsoft Office\OFFICE11" folder a program called selfcert.exe can be found, which will allow you to create a self signed cert. I know on my old Delphi 3 Ent, I had the signcode.exe program that you will need to get hold of in order to digitially "sign" your exe application. For VB, the task seems much easier as they the tools readily available.

Anyways, once signed, the private cert can be imported into Outlook, which will then let your program run unhindered.

There you can purchase a component set that should help you to include task items into Outlook. They also offer you a solution to bypass the Outlook security, which you will need when using Outlook 2003.

I am not trying to develop an add in, but rather automate outlook to add a new task via my program.

Russel,
Your example works fine. One little thing though:

When I use

ovItem.Reminderdate := '7/23/2006'

I get error message Method 'ReminderDate' not allowed?
Any way I can add a reminder date to the task?

There seems to be a little confusion...
First, the ReminderTime (eg '7/28/2006 08:00AM') is the property that needs to be set, along with ReminderSet:=True. But this is only supported if you are creating a task for yourself. (eg, no recipients / no Assign). Its an either / or situation. If you wish to visually see the logic, go into Outlook and create a new task. You will notice that you can set the reminder date/time, but notice what happens when you click the assign button.

Russell
