Object reference not set to an instance of an object

pj
Can anyone help? I getting this error on line 17:

Object reference not set to an instance of an object.

Line 15: Dim UserGUID As Object = User.ProviderUs erKey
Line 16:
Line 17: DataSource.Inse rtParameters.Ad d("UserID",
UserGUID.ToStri ng())
Line 18: DataSource.Inse rt()

Here's my code:

Protected Sub CreateUserWizar d1_CreatedUser( ByVal sender As Object,
ByVal e As System.EventArg s)

Dim UserNameTextBox As TextBox =
CType(CreateUse rWizardStep1.Co ntentTemplateCo ntainer.FindCon trol("UserName" ),
TextBox)
Dim DataSource As SqlDataSource =
CType(CreateUse rWizardStep1.Co ntentTemplateCo ntainer.FindCon trol("InsertExt raInfo"),
SqlDataSource)

Dim User As MembershipUser =
Membership.GetU ser(UserNameTex tBox.Text)
Dim UserGUID As Object = User.ProviderUs erKey

DataSource.Inse rtParameters.Ad d("UserID", UserGUID.ToStri ng())
DataSource.Inse rt()

End Sub

pj,

The User variable likely has the value null. If the specified userid is not
known then Membership.GetU ser(string) will return null.

hi pj,
you are calling a method on a null object, hence the Null reference
exception. User.ProviderUs erKey is null, so you can't call .ToString() on
it.
there must be something you are not initialising correctly with the user
object. i suggest you read the SDK pages for this class to see how to set
it up correctly.

Hello =) I have an object which contains a method that should execute every x ms. I can use setInterval inside the object construct like this - self.setInterval('ObjectName.methodName()', this.pinginterval); - but is there no way to do this without using the literal ObjectName? If I write 'this.methodName()' I get "Line 1 Char 1: Object doesn't support this property or method." in IE, and nothing happens in Firebird.

I'd like to be able to get the name of an object instance from within a call to a method of that same object. Is this at all possible? The example below works by passing in the name of the object instance (in this case 'myDog'). Of course it would be better if I could somehow know from within write() that the name of the object instance was 'myDog' without having to pass it as a parameter. //////////////////////////////// function...

Here are some questions that i am interested about and wanted to here an explanation/discussion: 1. (general) Is the objectness in JavaScript was supported from the very first version of it (in browsers) ? What about the new syntax of creating a object using { 'propName1':'propValue1', 'propName2':'propValue2', 'propName3':{ /* another object */ } } - from what version of JScript/JavaScript it was supported (from what browsers versions) ?...

Hi all, I've got a little hole in my head concerning references. Here's what I'm trying to do: I'm calling a function, passing the reference of a business object for editing. The function clones the object, calls an editor dialog to let the user edit the object, and then - depending on the DialogResult - assigns either the clone/backup copy or the modified object itself to the reference. Maybe I'm thinking too much in pointer references...

A global variable is really just a property of the "Global Object", so what does that make a function defined in the global context? A method of the Global Object? http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Guide:Defining_Functions doesn't actually give any insight.
