Note also: public mutable fields are a very bad idea on a value-type. If I translate that to C#, the compiler error is: Inconsistent accessibility: property type 'SklepPobieranieDanych.Transakcje' is less accessible than property 'SklepPobieranieDanych.TestTransakcje' which makes the problem pretty clear. share|improve this answer edited Sep 8 '14 at 6:55 answered Sep 8 '14 at 6:50 Marc Gravell♦ 628k14617532224 Thank y

Accessing the element is not a problem. visual basic structure However, when I try to update the value, the compiler complains: "Expression is a value and therefore cannot be the target of the assignment" For example: Public Structure Person Dim first as String Dim last as String Dim age as Integer End Structure _ Public Sub ListTest() Dim newPerson as Person Dim records as List (Of Person) records = new List (Of Person) person.first = "Yogi" person.last = "bear" person.age = 35 records.Add(person) records(0).first = "Papa" ' <<== Causes the error End Sub vb.net data-structures share|improve this question edited May 18 '15 at 15:01 Peter Mortensen 10.2k1369107 asked Aug 19 '11 at 19:15 hydroparadise 1,39721734 8 Every .NET programmer makes this mistake once. A Structure is a value type, records(0) returns a copy. Updating the "first" member of the copy doesn't accomplish anything. Person needs to be a Class. –Hans Passant Aug 19 '11 at 19:18 Darn carry-over assumptions from c++ ;). Thanks for the tip. –hydroparadise Aug 19 '11 at 19:22 @Hans: yeah, it is easy to forget that even records(0) will
Passing a Variable Number of Arguments Preserving Data Between Procedure Calls Understanding Scope Handling Runtime Errors Unstructured Exception Handling Structured Exception Handling Introducing Classes and Objects Summary Q&A Workshop ⎙ Print + Share This Page 1 of 13 Next > Master the concepts behind procedures, error handling, classes, and objects to create your foundation of Visual Basic .NET knowledge. From here, you will be able to get on your way to ascertaining full understanding of the language. This chapter is from the book This chapter is from the book Sams Teach Yourself Microsoft Visual Basic .NET 2003 in 21 Days, 2nd Edition Learn More Buy This chapter is from the book This chapter is from the book Sams Teach Yourself Microsoft Visual Basic .NET 2003 in 21 Days, 2nd Edition Learn More Buy Today, we're going to look at some crucial aspects of the Visual Basic language: procedures such as Sub procedures and functions, procedure scope, and exception (runtime error) handling. We'll also get an introduction to a topic that's become central to Visual Basic: classes and objects. Now that our code is growing larger, it's good to know about procedures, which allow us to break up our code into manageable chunks. In fact, in Visual Basic, all executable code must be in procedures. There are two types of procedures: Sub procedures and functions. In Visual Basic, Sub procedures do not return values when they terminate, but functions do. If you declare variables in your new procedures, those variables might not be accessible from outside the procedure, and that fact is new also. The area of your program in which a data item is visible and can be accessed in code is called scope, and we'll try to understand scopea crucial aspect of object-oriented programmingin this chapter. We'll also look at handling runtime erro
