An element declared within a class is not global, but if declared as public can be accessed outside of the class. In order to do that you must reference the class. For example: You have a global variable declared in your project: Public Var1 As Integer 'Global, accessable anywhere in the program Then you have a class that can use that variable: Public Class TestClass1 Public Var2 As Integer 'Accessable from outside the class Private Var3 As Integer 'Accessable only in the class Public Sub MyProc() Dim Var4 As Integer 'Accessable only in this method Var4 = Var3 'This is OK because Var3 can be accessed anywhere in the class End Sub Private Sub MyProc2() Dim Var5 As Integer 'Accessable only in this method Var5 = Var1 'This is OK because Var1 can be accessed from anywhere. End Sub End Class If you have a global instance of that class: Public TestClassObj as TestClass1 Then you can access public data inside that class: Public Class TestClass2 Private Var6 As Integer Public Sub DoSomething() Var6 = TestClass1Obj.Var2 'This is OK because TestClass2 has indentified where Var2 can be found End Sub End Class So, the VB doc you mentioned was correct, but you have be carefull where you declare your elements and always mind program scope.

Thanks for the reply. But I'm new to .NET. If you mean, have the main form inherit from System.Windows.Form.IContainerControl it doesn't work. At least I get an error that says classes can inherit only from classes.

Have a look at my article http://www.codeproject.com/useritems/nBASS.asp[^]. That is one feature I havent tested yet, but the BASS API can do that. (just had a look, and I havent done that yet :( havent had a need really, but you can load from a short[](16-bit) and play that. It is something I have been playing with recently, so it mite not be in the version on CP. Give me shout if its not there. Look for these functions: nBASS.BASS.LoadStream that takes a short[] as a parameter. Cheers :) PS: If you can mail me a "RAW" audio file, I will try make it work. :) Before you criticize a man, walk a mile in his shoes. That way, when you do criticize him, you'll be a mile away and have his shoes.

I have big problem for making class deriving from FileStream or BinaryReader I need to read a binary file into a some struct. Pleas help.
