<p>비주얼 베이직을 공부하며 작성한 프로그램 코드들을 설명을 덧붙여서 올릴 계획입니다. Visual Studio 6로 오래 전에 짜보고는 간만에 Visual Studio 2015로 넘어와서 해보는데 좀 바뀐점이 있어서 헷갈리는 군요.</p>



<p>2016. 8. 20.&nbsp; 최초작성</p>







<p>Visual Studio를 실행시킨 후 메뉴에서 파일 – 새로 만들기 – 프로젝트를 선택합니다.</p>



<p>왼쪽 창에서 Visual Basic – 창을 선택하고 오른쪽 창에서 Windows Forms 응용 프로그램을 선택합니다. 프로젝트의 이름으로 HelloWorld를 입력하고 위치는 나중에 찾기 쉬운 위치로 변경하도록 합니다.</p>

<p>이제 버튼을 누르면 라벨의 내용이 바뀌도록 해보겠습니다.&nbsp;버튼을 더블클릭하면 코드를 입력할 수 있는 창이 보입니다. 다음 코드를&nbsp;입력합니다.</p>



<pre><code>Public Class Form1
