Yes, that's what I was thinking. I usually create the object in code, but I think you should be able to do something like this.

In your child form, add this function:

    Public Sub New(ByVal myDataset As DataSet)

        Me.New()

        MyFormDataset1 = myDataset

    End Sub

Now, where you declare the child form in your parent form's code, use the new constructor and pass in your datset as the parameter.
