               List<Database.SaveResult> Result=srList;
                //Failed Records
                failedconlist=new List<contact>();
                for (Integer i = 0; i<srList.size(); i++) {

Hello Experts ,

Description :
i have a visualforcepage called 'generate_records' and 'schedulebatch' custom controller .From Controller i am calling batch class(MyBatchclass) and which process the large number of records .

Help Needed :
When user clicks on button that bacth starts running in the backgroud .so till the process is completed user should wait .Can you please help me how to show user something like"Loading plese wait" till the process is completed and then redirecing to some other page.

Hello All ,
We have VisualForce page which includes button called 'Generate'  so when we click on that button apex class( 'createRecord' ) will be called and which will create two types of objects records .

Issue :Now the problem is the apex class is creating more number of records which is hitting governor limt(Error :CPU Limit Exceeded) .

So we are planning to conver apex class to Batch apex class to avoid hitting governor limits .

Help Needed :
Since apex class is undergoing with many Lists ,Maps and validations in apex class before preparing final records list to insert ..

So is it possible to call batch class from current apex class by passing two final list of records to insert to the batch class and do the insertion in excute method ?

If above is not possible then can we include all complex list ,maps and validation to get final insert list of records in batch class .if yes please give me an idea .

i am getting this error while logging through username and password through login.salesforce.com.But iam able to login into the application through SSO .

when data is coming into salesforce from some other database through integration how can we make particular field as required .Kindly give me the all possible ways.

i have below Trigger:

trigger AccountTrigger on Account (before update) {
    List<account> acclist=new List<account>();
    for(account acc:trigger.new){
        acclist.add(acc);
    }
    AccountTriggerHandler.updateaccount(acclist);
}

Class:

public class AccountTriggerHandler {
 Public static void updateaccount(List<account> acclist){
        List<account> updatelist=new List<account>();
        for(Account acc:acclist){
            acc.phone='90000324902';
                updatelist.add(acc);
        }}

So when iam triying updating records through Workbench  with account Name field as null also it is running fine.Ideally Account​ Name is RequiredField so we shoud get error while updating.iam confused weather it is due to order of execution or any other reason kindly help me out with this.

i have a site called abc contains a form . after user fills the form and submit he will enter into the new page with success message.
Now the problem is if he press back button in the browser it will move to the form again with all enterd values.if he re submite the page Duplicate record is getting created. Please help me out how to avoid entry through back button.

Hi,
 
I have a strange problem..
 
I have a class where I'm inserting the records to an object from that class.
Lets say the object is Data__c..
 
I have all records in one list variable. Suppose i have 5 records in that list..
 
so., if i wrote
 insert data;(data is a list variable) all 5 records are inserted successfuly.. But I have a trigger on that object(before insert)..
 
For five records trigger is firing only once.. That trigger is firing only for the last record..
 
How to do an insert in which for all the records trigger will fire one by one..
 
Thanks
Raj

Hello

Can someone explain when to use different collection types in Apex with some real-life scenarios? 

Some explanation why a certain collection is used would be awesome. (Especially on maps!)

Additionally, are there any collection-specific limitations or best practises which would be good to know?

Thank you!

Hello All,
   i have gone through list and map, would any one share same example using LIST and MAP using 2 object. i am still confused when do i use list and when do i use map? please give me one common example , how MAP reduces code over LIST ?

Thanks,
 

Hi  All, I would like to know what is the Difference between Apex sharing and and sharing rules. If anybody know the difference please share to me.

Can any one please let me know when do we use list? when do we use map? when do we use set?

 

I'm bit confused regarding their usage.

I am new to programming in apex am studding from apex code developer guide.

 

I need some assignments so that I can practices some body provide me some link on a PDF so that I cold get some help.

Hi,

 

I have read the Apex concepts but I am not getting enough confidence in Apex coding, probably I need to practice more.

I was looking for Apex code examples/samples and use cases in google, but couldnt get any.

Can you please let me know if you have links to the Apex code examples/samples and use cases for Apex to try practicing.

 

Also for Apex classes and triggers, please let me know the following:

 

1. On which parts of Apex, I need to start for code practice and how to proceed further.

2. While practicing, what should be the areas that I need to practice more

3. What areas of Apex are commonly used

4. What areas of Apex are complex which needs more practice

5. How to frame the use cases myself for Apex code practice.

 

 

Thanks,

Priya.
