Murach’s Visual Basic 2008, C1 © 2008, Mike Murach & Associates, Inc. Slide 12 4 8/26/2008 Project and solution concepts
· Every Visual Basic project has a project file with an extension of vbproj that keeps track of the files that make up the project and records various settings for the project.
· Every solution has a solution file with an extension of sln that keeps track of the projects that make up the solution.
· When you open a project file, Visual Studio opens the solution that contains the project. And when you open a solution file, Visual Studio automatically opens all the projects contained in the solution.
· The project file can be stored in the same directory as the solution file or in one of its subdirectories. Murach’s Visual Basic 2008, C1 © 2008, Mike Murach & Associates, Inc.

· The Solution Explorer uses different icons to distinguish between source code files that define forms and those that don’t.
· Each form is defined by two Visual Basic source files where each file contains a partial class. The file with the vb extension contains the code that’s entered by the programmer; the file with the Designer.vb extension contains the code that’s generated when the programmer works with the Form Designer. When the project is compiled, these partial classes are combined into a single class that determines the appearance and operation of the form.
· A source code file that doesn’t define a form is usually stored in a single Visual Basic source file that contains a single class.
· The References folder contains references to the assemblies for the namespaces that the application can use. These namespaces contain the classes that the project requires. In most cases, all the references that you need are included when the project is created. Murach’s Visual Basic 2008, C1 © 2008, Mike Murach & Associates, Inc.

Murach’s Visual Basic 2008, C1 © 2008, Mike Murach & Associates, Inc. Slide 18 6 8/26/2008 How to rearrange windows
· To undock a docked window so it floats on the screen, drag it by its title bar away from the edge of the application window or double­click its title bar.
· To dock a floating window, drag it by its title bar onto one of the positioning arrows that become available. Or, double­click its title bar to return it to its default location.
· To hide a docked window, click its Auto Hide button. Then, the window is displayed as a tab at the edge of the screen, and you can display it by placing the mouse pointer over the tab.
· If two or more windows are grouped into tabbed windows, you can display any window in the group by clicking on its tab.
· If you dock, undock, hide, or unhide a tabbed window, all the windows in the group are docked, undocked, hidden, or unhidden. Murach’s Visual Basic 2008, C1 © 2008, Mike Murach & Associates, Inc. Slide 19 The form that’s displayed when the Financial Calculations project is run Murach’s Visual Basic 2008, C1 © 2008, Mike Murach & Associates, Inc. Slide 20 How to build a project without running it
· Use the BuildàBuild Solution command. Or, right­click the project in the Solution Explorer and select the Build command from the shortcut menu. This builds the Intermediate Language for the project and saves it in an assembly. How to run a project
· You can run a project by clicking on the Start Debugging button in the Standard toolbar or by pressing F5. Then, the first form of the project is displayed on top of the Visual Studio window.
· If the project hasn’t already been built, the project is first built and then run. As a result, it isn’t necessary to use the Build command before you run the program.

· Click the Close button in the upper right corner of the startup form.
· Click the button control that’s designed for exiting from the application. This is typically a button that is labeled Exit, Close, or Cancel.
