Yes the Cloud was a disruptive technology, but is it really a revolutionary concept or an evolutionary concept.
Many would believe it to be a revolutionary concept, but I differ, sorry Mr Benioff. It is evolutionary because really all that happens in the Cloud is that a computer has been picked up from 1 building and put in another. Yes, there is a little more to it than that, yes it provides SaaS and PaaS etc. But to consider it to be revolutionary it is not. It's not like moving from gas burning lights to electric ones, which is truly revolutionary.
Don't get me wrong I'm a massive advocate of the Cloud and wholly believe in it. Actually its massive success is partly due to it being an evolutionary concept rather than a revolutionary one, because it is easier to adopt evolutionary concepts.
But how will the Cloud develop. Well we are already seeing multiple types of Clouds springing up, Salesforce, Cordys, Azure, Sugar CRM, Google, Citrix, Redhat etc. Organisations are now not just licensing multiple instances of Clouds, such as 2 Salesforce Clouds dealing with 2 separate sides of a business ( Finance / Customers / Suppliers etc ), or Salesforce Clouds in partnered organisations connecting and sharing information, but also different types of Clouds, Salesforce, Sugar, Google etc communicating together in a thunderstorm of Clouds.
But I believe the real advantage of the Clouds like Salesforce and how it will leverage new technologies is the fact that Salesforce enforces a uniform foundation and language, so communication and crowd sourcing is far easier. Because of this although technologies like Salesforce is not OpenSource I believe cross-Cloud communication and crowd sourcing will exponentially increase bringing new and amazing capabilities to the Cloud.

Able To Run As Another User
There are times that you don't want to give permissions to specific users permanently, so it would be useful if you could temporarily turn on and off running code under a certain user.
Eg: to allow users to create data in Custom Settings requires to either turn on Customize Applications permissions or to give Delegated System Admin privileges to Non System Admin users.
The only problem with Customize Applications and Delegated System Admin privileges is that it opens the door to greater permissions for those users.
The answer will be to temporarily give permissions in code using System.runas() but this is only allowed in testmethods
If it was possible to run code like below in normal code
Profile prID = [Select id From Profile where Name Like 'System Administrator' LIMIT 1];
list<User> usr = [Select id From User where ProfileID=:prID.id and IsActive=true limit 1];//take 1 user which will always exist
if (usr.size() > 0){
system.runas(usr[0]){
object1__c newobject1 = new object1__c ();
}
}
else{
...
}

Create Drop Down List From Picklists
Sometimes its not possible to use <apex:inputfield /> or
<apex:selectList size="1" id="dependentField" required="false" value="{!aTask.1stfield}" .>
to display values from a picklist.
So I wondered how do I find the values in a picklist through code and display them on the page.
The code below shows a function getTaskStatus() which uses the functions getTheseSelectOptions() and getThePicklists() which find values from any picklist field and exclude any values which you want to exclude.
<apex:selectList size="1" required="false" value="{!aTask.2ndfield}">
<apex:selectOptions value="{!TaskStatus}" />
</apex:selectList>
public Task aTask {get;set;}
public List<SelectOption> getTaskStatus() {
//gets the picklists
List<SelectOption> options = new List<SelectOption>();
String[] excluded = new String[]{''};
options = getTheseSelectOptions('<<object>>','<<picklist field>>',excluded,false);
return options;
}
public static List<SelectOption> getTheseSelectOptions(String thisObject, String thisField, List<String> excluded, Boolean optionalBlank) {
List<SelectOption> options = new List<SelectOption>();
if (optionalBlank)
options.add(new SelectOption('' ,'' ));
try{
List<Schema.PicklistEntry> returnPicks = getThePicklists(thisObject, thisField);
if (returnPicks == null)
return null;
String thisPickValue;
Boolean ExclusionExists;
for (Schema.PicklistEntry EachVal: returnPicks){
thisPickValue = String.valueof(EachVal.getValue());
//search each Exclusion for this thisPickValue
for (String EachExclusion: excluded){
if (thisPickValue != EachExclusion)
options.add(new SelectOption(thisPickValue,thisPickValue)); //add thisPickValue if it is not in the Exclusion
}
}
}
catch(Exception e){}
return options;
}
public static List<Schema.PicklistEntry> getThePicklists(String thisobject,String thisFieldName){
List<Schema.PicklistEntry> picklists;
try{
Map<String, Schema.SObjectType> thisPickListMap = Schema.getGlobalDescribe();
Schema.SObjectType myObjectType = thisPickListMap.get(thisobject) ;
Schema.DescribeSObjectResult objResult = myObjectType.getDescribe() ;

How To SOQL On ActivityHistory
ActivityHistory is one of those rare objects that you cannot directly run a soql statement on.
eg: Select WhatId,CreatedDate From ActivityHistory]; is not allowed
So the trick is to place the soql within a nested soql. The Account object has a direct lookup field in the Task object, so the outer part of the soql can query the Account object first.
But say for instance you are interested on information in the history for Tasks related to another object, such as the Opportunity object. To get this information the following code could be used to grab this information.
Set<Id> opportunityIDsSet = new Set<Id>();
opportunityIDsSet.add(<<populate set with Opportunity IDs);
Map<ID,Datetime> oppMap = new Map<ID,Datetime>();
for (Account eachtaskhist: [Select id, (Select WhatId,CreatedDate From ActivityHistories where WhatId In :opportunityIDsSet << YOU COULD SET MORE SPECIFIC WHERE CRITERION AS YOU REQUIRE >>) From Account])
oppMap.put(eachtaskhist.ActivityHistories[0].WhatId,eachtaskhist.ActivityHistories[0].
CreatedDate);
oppMap will contain a Map of (<<Opportunity IDs>>, <<Date of ActivityHistory Was Created>> )
Just a note on this however, there are certain objects in Salesforce that cannot be soqled on by users other than by System Administrator users, ActivityHistory is one of those objects. So make sure you remove with Sharing in your classes.
Nice!!

Correct Way For Creating Unit Tests
When you deploy code to live your unit tests may work because there is data in the live environment. But, lets say a load of data is archived away, or as the status’s of data can change from say Pending to Active for example etc, maybe your soql in your unit tests which normally would return data it now doesn’t. So if the data is not there and your unit tests don’t create data then your units tests will fail and you won’t be able to deploy anything to live until its fixed.
Also if you refresh a sandbox, something you should do frequently; not all the data from live will populate your sandbox. So there is likely to be missing data. When you then start working on an existing class and you want to see if the unit tests pass, but they fail, because there’s no data in the sandbox and your test classes haven’t created test data. So you either have to find which data needs to be inserted and add the data to the sandbox, which you will have to remember to do this every time you refresh your sandboxes, or change the unit tests so that they create test data, the latter being the best option.
So as you develop you must deploy your code to an empty Sandbox where there is no data and run all your unit tests to prove that your unit tests create test data correctly.
So your unit tests must search for existing data and if it doesn’t find the data it must create the test data. So you might have something like this:
Function void createdata(){
list<Testdata__c> defaultEmail = new list<Testdata__c>();
defaultEmail = [Select ID__c,DefaultValue__c From Testdata__c Where ID__c='Default'];
//if soql returns nothing then create otherwise update
if (defaultEmail.size() == 0){
//data doesn’t exist so create new data
Testdata__c newTestdata = new Testdata__c(ID__c='DefaultVal',DefaultValue__c='test@aol.com');
insert newTestdata;
}
else{
//data exists so update it
defaultEmail[0].DefaultValue__c = 'test@aol.com';
update defaultEmail;
}
}
This code will not go in the unit test class, but in a separate class dedicated to creating test data so that this class can be used and shared by multiple test classes, lets call this class TestDatasCreation class. The only problem with this TestDatasCreation class is that it must also have unit test coverage. This is because the data will either exist or not exist in live, so without the TestDatasCreation class having its own unit test you will only test 1 part of the if statement block in the code above, where data exists or doesn’t.
To make sure that both if statement blocks are tested you could delete the data in the Testdata__c first to ensure that the 1st part of the if statement block is tested.
Delete defaultEmail; ( remove the data )
However in some objects deleting all the data in live this could break governor limits and also could cause your unit tests to take longer to run. Remember all unit tests are run when deploying code so delete statements like that will slow down deployments.
Instead if we change how the function is setup:
Function void createdata(String searchValue){
list<Testdata__c> defaultEmail = new list<Testdata__c>();
defaultEmail = [Select ID__c,DefaultValue__c From Testdata__c Where ID__c=: searchValue];
…..
}
Now if we assume that normally the 2nd part of the if statement block is tested by unit tests already created. To ensure that the TestDatasCreation class has also full unit test coverage:
//delete data first
list<Testdata__c> defaultEmail = new list<Testdata__c>();
defaultEmail = [Select ID__c,DefaultValue__c From Testdata__c Where ID__c='Default'];
Delete defaultEmail;
//1st part if statement block runs
Createdata(‘default’);
defaultEmail = new list<Testdata__c>();
defaultEmail = [Select ID__c,DefaultValue__c From Testdata__c Where ID__c='Default' limit 1];
//test created data
system.assert(defaultEmail[0].ID__c,'DefaultVal');
Of course the unit test for the TestDatasCreation class could be created to test both parts of the if statement block.
This will now give 100% test coverage for the TestDatasCreation class.
Also if you refresh a sandbox, something you should do frequently; not all the data from live will populate your sandbox. So there is likely to be missing data. When you then start working on an existing class and you want to see if the unit tests pass, but they fail, because there’s no data in the sandbox and your test classes haven’t created test data.

//data doesn’t exist so create new data
Testdata__c newTestdata = new Testdata__c(ID__c='DefaultVal',DefaultValue__c='test@aol.com');
insert newTestdata;
}
else{
//data exists so update it
defaultEmail[0].DefaultValue__c = 'test@aol.com';
update defaultEmail;
}

Of course the unit test for the TestDatasCreation class could be created to test both parts of the if statement block.
This will now give 100% test coverage for the TestDatasCreation class.
Using ObjectType
You can use ObjectType to easily display certain information on VF pages
The general format is
{!$ObjectType.<<object>>.<<field>>.<<property>>}
Display the plural text of an object
{!$ObjectType.Task.LabelPlural}
Display the 1st part of an object records id
{!$ObjectType.Task.KeyPrefix}
Display the length of a field
{!$ObjectType.Task.Fields.Await_Call_Back_Time__c.Length}
Display the help text of a field
{!$ObjectType.Task.Fields.Await_Call_Back_Time__c.InlineHelpText}
Display the data type of a field
{!$ObjectType.Task.Fields.Await_Call_Back_Time__c.Type}
Display the label of a field
{!$ObjectType.Task.Fields.Await_Call_Back_Time__c.Label}
Also for field sets

Salesforce Dependent Picklists
Salesforce has forgot to allow dependent picklists to be interrogatible by Apex.
If you are wanting to display dependent picklists on a VF page using a standardcontroller it easy, just use inputFields:
<apex:page standardController="Account">
<apex:form >
<apex:pageBlock mode="edit">
<apex:pageBlockButtons >
<apex:commandButton action="{!save}" value="Save"/>
</apex:pageBlockButtons>
<apex:pageBlockSection title="Dependent Picklists" columns="2">
<apex:inputField value="{!account.industry}"/>
<apex:inputField value="{!account.subcategories__c}"/>
</apex:pageBlockSection>
</apex:pageBlock>
</apex:form>
</apex:page>
However it becomes almost impossible when you use a custom controller
Options I considered was to use a javascript hack ( attached ), which although works on most pages the javascript reacts badly with the rendered visualforce elements especially when using rerenders etc
Code on VF page
<apex:includeScript value="{!$Resource.Prototype}"/>
<apex:includeScript value="/soap/ajax/15.0/connection.js"/>
<apex:includeScript value="{!$Resource.DependentPicklists}"/>
<apex:outputLabel styleClass="RightBold">Status</apex:outputLabel>
<apex:inputField onclick="helper.handleControllerChange()" styleClass="LeftAlign" id="controllingField" value="{!aTask.Status}"/>
<p></p>
<apex:outputLabel styleClass="RightBold">ControlledField</apex:outputLabel><br />
<apex:selectList id="dependentField" styleClass="LeftAlign" value="{!aTask.ControlledField__c}">
<apex:selectOption itemValue="None" />
</apex:selectList>
<script>
var dependentField = '{!$Component.dependentField}';
//alert(dependentField);
var controllingField = '{!$Component.controllingField}';
</script>
<script type="text/javascript">
var helper;
document.observe("dom:loaded", function(){
helper = new DependentPicklistHelper(
"{!$Api.Session_ID}","Task",
"Status","ControlledField__c",
controllingField ,dependentField
);
});
</script>
I also looked at apex interrogating the dependent picklists to produce selectlists on the VF page, but Salesforce has just forgot to provide this capability. Hence, this is where the problem begins.
So I considered adding an apex iframe which embeds another VF page and the controller to this page sets static variables in another class. The controller of the page that has the embedded iframe then uses the same static variables
which would hold the same value already set. This option could well be a valid workaround in some scenarios.
However I opted for a slick solution using static resources. I upload a csv file containing the values for the dependent picklists. I created a function to read the static resource and create a Map of the values. So now I have a Map representing the
exact values of the dependent picklists. All I needed to do now is display the values on the VF page and make the selectlist for the controlling picklist and dependent picklist to be linked.
To see this in action have a look at the following functions
getTheseMappedProperties()
getTheseTaskStatus()
getControlFieldVals()
//Note you need to create a csv file with matrix for the dependent picklist values and upload to Static Resources
public List<SelectOption> ControlledFieldValues{get;set;}

Multiple Object Pagination on 1 VF Page
In Salesforce you can easily paginate records on a single object
<apex:page standardController="Account" recordSetvar = "accounts" >
<apex:pageBlock title="ViewingAccounts">
<apex:form id="theForm">
<apex:pageBlockSection>
<apex:dataList var="a" value="{!accounts}" type="1">
{!a.name}
</apex:dataList>
</apex:pageBlockSection>
<apex:panelGrid columns="2">
<apex:commandLink action="{!previous}">Previous</apex:commandlink>
<apex:commandLink action="{!next}">Next</apex:commandlink>
</apex:panelGrid>
</apex:form>
</apex:pageBlock>
</apex:page>
I've highlighted the new bits in bold:
You can easily control the number of records displayed in each page (it defaults to 25), by writing an extension:
VF Page
<apex:page standardController="Account" extensions="tenPageSizeExt" recordSetvar
= "accounts" >
public class tenPageSizeExt {
public tenPageSizeExt(ApexPages.StandardSetControllercontroller){
controller.setPageSize(10);
}
}
But the problem occurs when you want to include multiple objects on a single page and paginate each object independent of each other
To demonstrate this I've created a VF page called GeneralSearch and Controller called GeneralSearchController.
The key thing is to use multiple ApexPages.StandardSetController and to use Database.getQueryLocator to iterate through the records
String qry = 'select Id,Name from Account where ....';
ApexPages.StandardSetController acct = new ApexPages.StandardSetController(Database.getQueryLocator(qry));
Here is some example code
public class EnumeratedValues {
public enum OpportunityEnum {Object1, Object2}
}
public with sharing class OppReporting {
//iterators
public ApexPages.StandardSetController object1{get; set;}
public ApexPages.StandardSetController object2{get; set;}
//the current page number for each object
public integer object1Pg{get; set;}
public integer object2Pg{get; set;}
//display results
public List<Opportunity> object1Return {get;set;}
public List<Opportunity> object2Return {get;set;}
//number of records to display comes from a custom setting
public integer numberRecordsToDisplay{get;set;}
public string setRecordsToDisplay{get;set;}
//pages to display for Task
public list<integer> object1StatusPagesToDisplay{get;set;}
public integer selectedPageObject1{get;set;}
//pages to display for object2 summary
public list<integer> object2PagesToDisplay{get;set;}
public integer selectedPageObject2{get;set;}
private Set<Id> newIDsSet;
public Map<ID,ID> object1IdToTaskID{get; set;}
public ID selectedObject1{get; set;}
//public Set<String> subjects;
public list<Opportunity> opps{get; set;}
//max pages to dislay
public long numberOfPagesToDisplayObject1{get; set;}
public long numberOfPagesToDisplayObject2{get; set;}
public list<object1List> allObject1List{get;set;}{allObject1List = new list<object1List>();}
public list<object2List> allObject2List{get;set;}{allObject2List = new list<object2List>();}
public OppReporting(){
//get the number of records to display on each page
