call apex method on keypress event

Hello
I having a custom object C1 with fields like name,email and mobile number.On an visualforce page I will enter the values and save the data.This part is fine with me.
Now my requirement is when I enter email in <apex:inputfield> say on keypress event I should be able to call an server side method in apex controller.
This method will check if the email already exists in object. If it exists then some action needs to be taken.

Please anybody any help will be greatly appreciated

jquery range slider problm

In opportunitylineitems object, I have field amount and three radio buttons i.e monthly , quarterly and yearly. I have a jquery slider in visualforce page , when I move the slider if I select radio button monthly then it should show the amount to be paid in a month, similarly, if radio button quarterly is selected then it will display amount to be paid in a quarter and so on. I picked up brief idea from the url http://blogforce9.blogspot.in/2012/02/jquery-slider-for-visualforce-pages.html about query slider but I am not sure as how to handle the apex class required for this.

when to use after trigger

Hello friends
I have a scenario where when a account field is udpated corresponding contact field descriptions also gets updated.
pls see code as follows , its working.

public class Account_ContactDescription
{
      public void Update_ContactDescription(Set<ID> accountIDs)
   {
      List<Contact> contactsToUpdate=new List<Contact>();
      
      List<Contact> conaccountIDs=[select Id,FirstName,LastName from contact where accountID IN :accountIDs];
      
      if (conaccountIDs.size() > 0 && conaccountIDs != NULL)
      {
         for(Contact con:conaccountIDs)
         {
         contactsToUpdate.add(new Contact(ID=con.ID, Description=con.FirstName+' '+con.LastName));
            
         }
      }
      
      Database.Update(contactsToUpdate,false);
   }
}

trigger trg_updateContactDescripton on Account (before Update) 
{
  
  if (trigger.IsUpdate)
  {
    Account_ContactDescription obj = new Account_ContactDescription();
    obj.Update_ContactDescription(Trigger.NewMap.Keyset());
  }
}

If I use after Update event also it works, then my question is what is the specific case scenario where a user is forced to use after trigger.
pls elaborate

search for a value in 2 million records

Hi
I am trying to understand how to go about below issue.
I have 2 million historical records in account object.
I have as follows:

public class somecontroller
{
    public String searchstring{get;set;}
    
    public list<Account> acc{get;set;}
    
    public somecontroller(ApexPages.StandardController controller) {}
    public PageReference Search()
    {
      string searchquery='select ID,Name from Account where name like \'%'+String.escapeSingleQuotes(searchstring)+'%\' ';   

      acc= Database.query(searchquery);   

      return null;
    }  
}
<apex:page standardController="Account"
           extensions="SomeController">
<apex:form>
     <apex:inputText value="{!SearchString}"
                                  label="Enter Account Name"/>
                   
     <apex:commandButton value="Search records" action="{!search}"/>  
 
     <apex:commandButton value="Clear records" action="{!search}"/>  
       
       <apex:pageBlock title="Search Result">  

     <apex:pageblockTable value="{!acc}" 
                          var="a">  
     <apex:column>  
     <apex:outputlink value="/{!a.id}">{!a.Name}</apex:outputlink>  
 
     </apex:column>  
 
     <apex:column value="{!a.id}"/>  

    </apex:pageBlockTable>     

   </apex:pageBlock>

If the number of rows is less than or equal to 50000 then its fine but if number of rows is more than 50000 then I will have to use a batch apex.
Now assuming 1 lakh rows are returned then how can I hold this result information in batch apex?
I may want to show these records in a PDF or excel.

I really hope I am very clear.
Please let me know.

User Mode and system Mode

Hello
I have some difficulty in understanding the following

a) Normally apex code & trigger run in system.context
But How to make the apex code execute in USER Mode?
if the apex code executing in USER Mode is called by a trigger, will the trigger also execute in USER Mode?

b) Can a visual force page run in USER Mode instead of system.context , again what changes need to be done and why?

c) By default webservice classes written in apex , rest api execute in what Mode?

d) what is the use of system.RunAs with respect to the above.

I hope I am clear

INSUFFICIENT_ACCESS_OR_READONLY

Hello friends
I am getting the error " INSUFFICIENT_ACCESS_OR_READONLY" when I execute apex code from trigger and the logic performs an DML operation.
I went through several posts to understand this error I understood that in the context of current user not having permission to perform edit on the object is resulting in this error.

The code was written by another user with 'WITH SHARING" keyword and also he has written as test class.
I checked with sysadmin so I do not have permissions to perform any edit on the said object.

My question is how do I resolve this error.

A) Can I actually remove the "WITH SHARING" keyword and then run the code from my login ?
B) In test class can I remove the option of 'WITHOUT SHARING"?
C) Also Pls lt me know how system.RunAs() works in the above context.
D) as of now this code is not deployed, so once it is deployed if this error occurs pls explain how to to resolve

I really hope I am clear.
