variable scope inside a method

Hi,

I'm having trouble with variable scope inside procedures.
this is pseudocode

LDAP NewUser;

if (something = true)
{
NewUser = LDAP.FindUser(u se emailaddress)
this.textbox1 = NewUser.name
}
else
{
NewUser = LDAP.FindUser(u se employeeID)
this.textbox1 = NewUser.name
}

I'd rather have this:

if (something = true)
{
NewUser = LDAP.FindUser(u se emailaddress)
}
else
{
NewUser = LDAP.FindUser(u se employeeID)
}

this.textbox1 = NewUser.name

however: i get the error unassigned use of NewUser. How do I declare NewUser
so that I can have access to its members outside of the if..else statement?

my real code has dozens of textboxes to fill and I don't want to duplicate
the same
statments twice.

thanks

chris

Chris,

You would do this:

LDAP NewUser = null;

And then the rest of your code.

Hope this helps.

Hi,

There is no need to set the variable to null , as it';s assigned in both
branches of the IF statement the compiler will not complain about it.

So the "use of unassigned variable" is not for that reason.

cheers,

Is there any difference between declaring a variable at the top of a method versus in the code of the method? Is there a performance impact for either choice? What about if the method will return before the variable is used?

Hello, I think I've had JavaScript variable scope figured out, can you please see if I've got it correctly? * Variables can be local or global * When a variable is declared outside any function, it is global regardless of whether it's declared with or without "var" * When it is declared inside a function, if declared with "var", it's local, if not, it's global
