FBA : Change Password

From my Earlier blog stating Form Based Authentication in SharePoint (MOSS 2007).
 ( Click Here )

Many were interested in password management for the users. A complete package ready to use is uploaded on codeplex.
However here I’m attaching a custom strip down to users change Password code snippet for the same.

There are two options while password management
1. Just to change Password
2. to provide Question & Answer along with Password change
Note : for Option (2) please add/updated web.Config file within Membership provider
------------------------------------------------------------------

///save button functionlity 
void btnChangePassword_Click(object sender, EventArgs e) 
{ 
if (Validate(true)) 
{ 
try 
{ 
string AppName = Membership.ApplicationName; 
if (.Text.Trim().ToString() != .Text.Trim().ToString()) 
{ .Text = " New and Confirm password Mismatch ! " ; } 
else 
{ 
if (Membership.Provider.ChangePassword(.Text, .Text, .Text)) 
{ //membership provider has Change Password checked in Web.Config
if (Membership.Provider.ChangePasswordQuestionAndAnswer(.Text, .Text, .Text, .Text)) 
{ 
//Message: " Your Password Has Been Sucessfully Changed.." 
return; 
} 
} 
catch (MembershipPasswordException ee) 
{//Exception Message} 
            }
}
