Sue,
thanks for the reply. Here it goes..
Outlook.Application app = new Application();
TaskItem item = null;
item = (TaskItem)app.CreateItem(OlItemType.olTaskItem);
item.subject = ...
item.MessageClass = "IPM.Task.MyCustomForm";
item.Save();
this code adds the item correctly but when i open the task for view my
custom form it just opens the default form. If i close and open outlook
applicaiton, the tasks now open in the intended "MyCustomForm".
Right now i've saved the form as a Outlook template and use the following
code.
Outlook.ApplicationClass appClass = new ApplicaitonClass():
Outlook.NameSpace ns = appClass.GetNameSpace("MAPI);
Outlook.MAPIFolder oTaskItems =
ns.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderTasks);
item =
(TaskItem)app.CreateItemFromTemplate("C:\myformTemplate.oft",oTaskItems);
item.subject = ...
item.MessageClass = "IPM.Task.MyCustomForm";
item.Save();
Using this code and adding the AllowActivexOneOffForms registry entry seems
to be working correctly. But i wanted to have the code piece #1 to be working
correctly. The forms are obviously published.
hope this helps
thanks
