Apex code for Alerts and Reminders

Hey all

 

I am looking to write some Apex code for a task manager app that I am building that allows the user to set a reminder and alert for the completiion of their task.  I understand I want to use:

 

IsReminderSet

ReminderDateTime

 

I'm not very good at code though and not sure how I would write the code to do what I want to do, can anyone help please?!

 

Many thanks

 

Andy

Hi,

 

here is the code example,

 

<apex:page controller="testtask">
<apex:form >
<apex:commandButton value="Create Task" action="{!createTask}"/>
</apex:form>
</apex:page>

 

public class testtask {

public PageReference createTask() {

Task newTask = new Task(Description = 'Survey Transaction111',
Priority = 'Normal',
Status = 'Inbound Email',
Subject = 'Other',
IsReminderSet = true,
ReminderDateTime = System.now()+1,
WhoId = 'UserIdHere'
);
insert newTask
return null;
}

}

 Please set a user Id in WhoId.

This is kind of old... but the error above is due to the fact that you can only Ids to lookup fields that are actually a part of the lookup... WhoId is limited to Contacts and Leads, and you are trying to pass a UserId to it. Same goes for WhatId, or any lookup field.
