Hi All, in my custom object I am having a cutom button"convert" when i click this button"convert"it will  create new Account,Contact and Opportunity. But I need to do same as Lead(Ie,. in Lead if click "convert" button it will go to an other page where we can existing Account for that or we can create a new Account. For creating Opportunity it will have a checkbox which will ask us whether we have to new opportunity for that record, after we made all this we again  "convert")

Like that when i click my custom button"convert" on my custom tab, it must go to another window from that page we have select Account for that(existing or new) if i select existing account means all Account must be displayed in the listbox, we have to select any from that and we have to  create a new opportunity for that record.

Here i have attached my Apex code to create Account, contact and opportunity.Also VF page code.

Apex code:

public class Convert
{

public PageReference RedirecttoSite()
{
String currentLead = '/' + siteObj.Id;
PageReference pageRef = new PageReference(currentLead);
return pageRef;
}

private Site__c siteObj;
//public ID Cus_Account_ID, Cus_obj_Record_ID;
// The extension constructor initializes the private member
// variable acct by using the getRecord method from the standard
// controller.
public Convert(ApexPages.StandardController stdController)
{
System.debug('******sai******');
siteObj = (Site__c)stdController.getRecord();
// Cus_obj_Record_ID=siteObj.Id;
}
List<Account> acctList = new List<account>();
public void convertbutton()
{

Account acc = new Account();
acc.Name = siteObj.Company_Name__c;
acctList = [select id from Account where Name = :acc.Name];
if (acctList.size() > 0)
{

ApexPages.Message errormsg = new ApexPages.Message(ApexPages.severity.ERROR,'Account Name ' + acc.Name + ' already exists,Duplicate Account Name not allowed');
ApexPages.addMessage(errormsg);
return;
}
acc.BillingStreet = siteObj.Company_Address__c;
acc.BillingCity = siteObj.Company_City__c;
acc.BillingState= siteObj.Company_State__c;
acc.BillingPostalCode = siteObj.Company_Postal_Code__c;
acc.Phone = siteObj.Company_Phone__c;
acc.Website = siteObj.Company_Email__c;
acc.Fax = siteObj.Company_Fax__c;
// acc.CurrencyIsoCode = siteObj.CurrencyIsoCode;

try
{
insert acc;
ApexPages.Message successmsg = new ApexPages.Message(ApexPages.severity.confirm,'New Account ' + acc.Name + ' is created, Related Contact and Opporunity also created' );
ApexPages.addMessage(successmsg);
}
Catch (Exception ex1)
{
ex1.getmessage();
}
Contact cc = new Contact();
cc.LastName = siteObj.Contact_Name__c;
cc.Email = siteObj.Contact_Email__c;
cc.Phone = siteObj.Contact_Mobile__c;
cc.AccountId = acc.Id;

try
{
insert cc;
}
Catch (Exception ex2)
{

ex2.getmessage();
}

Opportunity opp = new Opportunity();
opp.Name = siteObj.Opp_Name__c;
opp.AccountId= acc.Id;
opp.CloseDate = siteObj.Opp_CloseDate__c;
opp.StageName = siteObj.Opp_stage__c;
if(opp.StageName == 'Needs Analysis')
opp.Probability= 20;
else if(opp.StageName == 'Prospecting')
opp.Probability= 10;
else if(opp.StageName == 'Negotiation/Review')
opp.Probability= 90;
else if(opp.StageName == 'Closed Won')
opp.Probability= 100;
else if(opp.StageName == 'Closed Lost')
opp.Probability= 0;

try
{
insert opp;
}
Catch (Exception ex3)
{
 ex3.getmessage();
}

}
 }
