by default, public or private?I'm trying to find on MSDN, or someplace, that speaks to variables being
public or private by default. Anyone know where? Thanks. Hi all,
"If the Dim statement is used (in Visual Basic .NET) or no access modifier is used (in Visual C#), the variable is considered private in Visual C# and Visual Basic .NET classes, Public in Visual Basic .NET structures, and private in Visual C# structures. Methods do not require an access modifier. If no access modifier is specified, the method is Private by default if in a class or structure in C#, and Public if in a class or structure in Visual Basic .NET." --- MCAD/MCSD Training Kit Windows Apps.

The definition of a private variable is one that is not visible *outside* of the type to which it belongs (Class or struct). "Private" is the most you can limit the access level, and even all Private variables can be freely accessed within the class they are declared. > I believe it depends more on where the variable is declared. Yes, you are right about that. As above, variables in VB.NET structures areby default Public.

Since we're in the VB newsgroup, the posts about other languages don't apply.

Module Module1 Dim x As String Sub Main() x = "This is a string" Debug.WriteLine(x) End Sub End Module The variable is private to the module BUT public within the module. I believe it depends more on where the variable is declared. Joe -- Show quoteHide quote"Carlos J.

What are you talking about here? The scope of a class/module variable refers to its visibility outside the class/module where they are declared. Of course that a class or module-level variable is reachable within the class/module, how could it be otherwise? -- Show quoteHide quoteBest regards, Carlos J.

We can forget the DIM keyword because that adds nothing (and therefore the same as not used in C#). A value delclared inside a method can only be private to that method. A value on Class level can have other access rights. (See for that the message from Randy). A module is nothing more than a Class which has all his members shared global to the application (main class). Cor For all intents and purposes DIM and Private are equal.
There are three levels of scope. All variables declared within a procedure are private. Variables declared within a module are private to that module using either Dim or Private. Variables declared within a module as Public are accessible to any procedure inside or outside of that module. Again, my original statement stands, it depends on where you declare the variable. Not declaring it properly is just wrong!

Try: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcn7/html/vbconaccessibility.asp Or search help for "scope". But, the fact there is discussion about this means many people are in doubt about it. May I humbly suggest that you always declare your names explicitly.
