I'm trying to deploy something like this: 

public class Send {
    
    public Send(){ 
    }

    public static Messaging.SingleEmailMessage createEmail(
                         String SenderName, Id TemplateId, Id ObjectId, Id WhatId) 
    {
        Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();
        email.setTargetObjectId(ObjectId);
        email.setTemplateId(TemplateId);
        email.setWhatId(WhatId);
        email.setSenderDisplayName(SenderName);
        return email;
    }
    
    public static void MessageSent() {
        
        /* Create a list of email objects */
        Messaging.SingleEmailMessage [] emails = new Messaging.SingleEmailMessage[]{};
            
       /* Get a list of contacts */
        List<Contact> c = [SELECT Name, Id, AccountId
                           FROM Contact
                           WHERE Email != null AND Email != '' ];

        /* Find the size of all the contacts */
        Integer ContactSize = c.size();
        
        /* Locate the email template being used */
        EmailTemplate et = [SELECT id
                                    FROM EmailTemplate
                                    WHERE Name = 'CAF VF'];

/* Iterate through the list of contacts and send email to each */
        for (Integer i = 0; i < ContactSize; i++){
                
                Messaging.SingleEmailMessage temp = createEmail('Report', et.id, c[i].Id, c[i].AccountId);
                emails.add(temp);
            }
        
            try{
                Messaging.sendEmail(emails);
            } catch (Exception e) {
                System.debug('The following exception has occured: ' + e.getMessage());
            }         
    }
}

I get the following errors: 
 - System.NullPointerException: Attempt to de-reference a null object, Stack Trace: Class.MassUpdateSimpleControllerTest.testOpportunityInRelatedList: line 148, column 1
- System.AssertException: Assertion Failed, Stack Trace: Class.Milestone1_GettingStartedController.testGettingStartedProject: line 239, column 1

I have no idea how to fix this. Help me, please!

I have a Visual force page and I want the user to be able to go to that page on click of a button on the homepage. How can I add such a button to the homepage? Thanks!

I have a list of accounts and I want to display all the partners for one particular account in an email sent to that account. I'm using a Visual Force email template but I don't know how to fetch all the account-related partners in the email template. Can someone please help? Thank you!

I want to display all the account-related partners in a Visualforce email template:

relatedToType="Account"
<apex:repeat var="op" value=?>
...
I want value to be a list of all the partners related to the current account. I tried inserting a query: value="{!SELECT Name FROM Account WHERE Id IN (SELECT AccountToId FROM Partner WHERE AccountFromId = relatedTo.Id)}"

The code fails. Can someone help me with this?

I'm having trouble understanding the relationship between Partner and Opportunity. I want to access the data of the partner related to an opportunity. Opportunity has a field called PartnerAccount:

However when I use this code: SELECT PartnerAccount.Name FROM Opportunity
There is an error: No such relation 'PartnerAccount' on entity 'Opportunity'

Can anyone tell me why? And how could I access the information in partner when I'm querying opportunity? Thanks!
 

This is what I want to do: 
SELECT Account.Name FROM Account WHERE Business_Type__c like '%Manufacturer/Supplier%'

However I'm getting this error: invalid operator on multipicklist field. Could you tell me what it means and how to fix it?

Hi, I created a custom lookup relationship so that I can access Opportunity when I'm querying Contact:


What I want is something like this:

SELECT Email, Look_Opportunity__r.Stage FROM Contact WHERE Oppportunity.Stage != "Not Ready" AND Email != null

However, when I call this the query it returns null for Look_Opportunity: 

What's wrong with my code? Many thanks for the help!

Hi, I want to select from Contacts all of the contacts that have opportunities. I used the code below but it's not working:

SELECT Name, (SELECT Name FROM Opportunities) FROM Contact WHERE AccountId in (SELECT AccountId FROM Opportunity)

I know how to select through Account, but I want to know how to do it this way. Thank you!

Hi everyone, I'm a complete newbie to Apex and I'm recently writing an email template that sends out all of the opportunities related to a specific account name. However I don't fully understand what <apex:repeat> does.

In <apex:repeat var="op" value="{!relatedTo.Name}">, what does "var" refer to and what does "value" refer to? Does this create a loop that iterates through all of the records in relatedTo that have Name equal to value? 

Please help me with this! Thank you so much!
