User Properties RRS feed

  • Question

  • It is my understanding that code will error if you try to access a user property that doesn't exist i.e

    app.UserProperties.Find("oGID", true).Value

    so I have the relevent code

                        if (app.UserProperties.Find("oGID", true) == null)
                            app.UserProperties.Add("oGID", Outlook.OlUserPropertyType.olText, true, Outlook.OlUserPropertyType.olText);
                        app.UserProperties.Find("oGID", true).Value = app.GlobalAppointmentID;

    to create the relevent property if it doesn't exist before assigning a value to it, is there a better way to do this?

  • Keep in mind that Add returns UserProperty object. Your code ignores the returned value.

    Alos note that you can call UserProperties.Add even if the property already exists and you won't get a duplicate:

    UserProperty prop = app.UserProperties.Add(...);

    prop.Value = app.GlobalAppointmentID;
