An example in a book using that method checked the return against Nothing. Is Nothing the VB equivalent of null?If the book is written for C#, yes. But ''Nothing'' will work for valuetypes too.--Herfried K.

But ''Nothing'' will work for value types too.Not sure what that means. Is the following correct?Does it mean I can set an object variable to null or to Nothing,while an integer variable can be set to Nothing but not to nullIs setting an integer variable to nothing the same as setting it to zero?Setting an object variable to null means it does not reference an object? -- Herfried K.
