Generate strong random password in Apex

Hi Coders,

I thought this might be handy so thought of sharing this .

It will create a random password with specified length  

public String generateRandomString(Integer len){
        String randStr = '';
        final String upperChars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
        final String numChars = '0123456789';
        final String LowerChars = 'abcdefghijklmnopqrstuvwxyz';
        final String specialChars = '!#$%-_=+<>';
        while (randStr.length() < len) {
           Integer idx = Math.mod(Math.abs(Crypto.getRandomInteger()), upperChars.length());
           randStr += upperChars.substring(idx, idx+1);
           idx = Math.mod(Math.abs(Crypto.getRandomInteger()), numChars.length());
           randStr += numChars.substring(idx, idx+1);
           idx = Math.mod(Math.abs(Crypto.getRandomInteger()), LowerChars.length());
           randStr += LowerChars.substring(idx, idx+1);
           idx = Math.mod(Math.abs(Crypto.getRandomInteger()), specialChars.length());
           randStr += specialChars.substring(idx, idx+1);
        }
        return randStr; 
    }

Happy Coding !!!!!!!!!!!!!!!

How to terminate AsyncApexJob [EXCEPTION: System.StringException: You can't abort scheduled apex ]

I thought this might be useful to developers. 

EXCEPTION: System.StringException: You can't abort scheduled apex : This exception may happen for 2 reasons

1. It is not a CronTrigger ID (parent Id) for the Async Apex job 
2. You are trying to delete a orphan Async Apex job, that is no parent Id.

Second situation is rare but it can happen. In that case you might face problem while deploying  the batch class again. The deployment will fail as the batch is already executing (queued )  for a long time.

If this happens you need to call saleesforce support to clear this. BUT before you call salesforce support please tray this which might help .

1.  login to "https://workbench.developerforce.com/login.php" 
2. On right corner, it will be showing your name and API version. Click on that link
3. There you will find change API version, change it to 32
4. Go to Utilities >> Apex Execute
5. There run this command System.abortjob() with job Id

Please note the API version is very important we can't do this from developer console because we can't change the API version there, alternatively you may choose the version during login as well while logging -in to workbench. I believe this would help you. Please let me know if you have any other questions, I would love to help you in that as well.

Have a Great Day! 

Get Salesforce record ID from lookup field in Visualforce page

Hello Friends,

Recently I was working on a requirement where I have to validate some lookup field on visualforce page itself not in apex without submitting form to server. 

I did lots of research and after having a lots of dig down of salesforce source code I identified each lookup field is associated with one hidden field with a "_lkid" appended to the id this help me to identify the record uniquely 

<apex:page standardController="Contact">
   <apex:form>
      <apex:inputField value="{!Contact.AccountId}" id="accountId onchange="getAccountSFId();">
          <script>
                  var accountId = "{!$Component.accountId}";
          </script>
   </apex:form>
   <script>
           function getAccountSFId(){
              var accId =  accountId + '_lkid';  
              // This will give you the 18 digit SF id of the account and you can do what ever you want with this 
              console.log(document.getElementById(accId ).value);
           }
   </script> 
</apex:page>

Dealing with multiple JQUERY load and avoiding conflict with bootstrap

Hello Everyone.

Today I faced CSS and JQUERY confident issue very badly. I have to use JQUERY week calender which run under jquery 1.4 and have to use bootstrap3 now the catch is bootstrap need a higher version of jquery to run .

How i resoled the above problem . after doing lots of research and search in stack overflow I found the solution

1) For JQUERY CONFLICT :

<script src="jquery1" />
<script src="jquery2" />
<script>
jQuery.noConflict();
</script>

Now where ever you are using bootstrap use 

<script>
jQuery(".class").fun();
</scrirt>

2) The CSS conflict . 

Wrap bootstrap CSS with name space .

Reset user password from APEX in case of user lockout

With winter 16 we have issue with password lockout when we have two factor enabled

Click here to see the issue

We are experiencing so many lockouts so I came up with this 

global class scheduledPasswordReset implements Schedulable {

 global void execute(SchedulableContext SC) {
Set<String> Ids = new Set<String>();
Set<String> LockIds = new Set<String>();
for (LoginHistory l : [SELECT UserId,LoginTime, status FROM LoginHistory WHERE LoginTime = TODAY ORDER BY LoginTime DESC  ]){
if(!Ids.contains(l.userId)){
Ids.add(l.userId);
if(l.status == 'Password Lockout'){
LockIds.add(l.userId);
}
}
}
system.debug('### '+LockIds);
for(String uId : LockIds){
 System.resetPassword(uId, true);
}

   }

}

@chatter Mention user

Hello everyone after the version 31 below methods are no longer available 

ConnectApi.ChatterFeeds.getFeedItemsFromFeed(null, ConnectApi.FeedType.News, userId);

So how we can do @mention now . see sample code below how to do that .

// Method that takes the list sobject as  parameter and post 

    public static void postOnChatter(List<Sobject> Items){
        List<ConnectApi.BatchInput> batchInputs = new                      List<ConnectApi.BatchInput>();
Integer MAXSIZE = 10 ;// Select Your size
        for (Sobject item : Items) {
            //  initialize the FeedItemInput
            ConnectApi.FeedItemInput input = new ConnectApi.FeedItemInput();
            input.subjectId = item.Id;
            
            // initialize the body of the chatter post
            ConnectApi.MessageBodyInput body = new ConnectApi.MessageBodyInput();
            body.messageSegments = new List<ConnectApi.MessageSegmentInput>();
            
            // add the mention to the post
            ConnectApi.MentionSegmentInput mentionSegment = new ConnectApi.MentionSegmentInput();
            mentionSegment.id = item.OwnerId;
            body.messageSegments.add(mentionSegment);
            
            // add the text containing the Product Name and the tracking information
            ConnectApi.TextSegmentInput textSegment = new ConnectApi.TextSegmentInput();
            textSegment.text = 'Sample Text';
            body.messageSegments.add(textSegment);
            
            input.body = body;
            ConnectApi.BatchInput batchInput = new ConnectApi.BatchInput(input);
            
            // add the FeedItemInput instances to a list
            batchInputs.add(batchInput);
            
            // postFeedElementBatch() method can process maximum of 500 feeds at a time
            // if the feeds are 500, post them and re-instantiate the list
            if(batchInputs.size() == MAXSIZE){
                ConnectApi.ChatterFeeds.postFeedElementBatch(Network.getNetworkId(), batchInputs);
                batchInputs = new List<ConnectApi.BatchInput>();
            }
        }
        // post the feeds  in the list
        if(batchInputs.size() > 0)
            ConnectApi.ChatterFeeds.postFeedElementBatch(Network.getNetworkId(), batchInputs);
    }
