Chapter 4 Working with Menus, Toolbars, and Dialog Boxes 115

1. Click the Start Debugging button on the Standard toolbar.

The program runs, and the Clock menu and the toolbar appear at the top of the screen.

2. On the form’s toolbar, click Open.

The Open dialog box opens. It looks great, doesn’t it? (In other words, it looks just like

a regular Windows application .) Notice the Bitmaps (* .bmp) entry in the dialog box. You

defined this entry with the statement

OpenFileDialog1.Filter = "Bitmaps (*.bmp)|*.bmp"

in the OpenToolStripButton_Click event procedure. The first part of the text in quotes—

Bitmaps (* .bmp)—specifies which items are listed in the Files Of Type box. The second

part—* .bmp—specifies the file name extension of the files that are to be listed in the

dialog box.

3. Open a folder on your system that contains bitmap images. I’m using the color toolbar
   button I’ve used in this chapter (located in C:\Vb10sbs\Chap04), but you can display any
   .bmp file on your system.


4. Select the bitmap file in the Open dialog box, and then click the Open button.

A picture of the bitmap appears in the picture box. My form looks like this:

Now you’ll practice using the Clock menu.

5. On the Clock menu, click the Time command.

The current time appears in the label box.
