Read Data Matrix ECC200 in Java Value Image ImageAndText None Text

Description The ToolStripItem may display only an image, which is the default The ToolStripItem may display both an image and text The ToolStripItem may not display either an image or text The ToolStripItem may display only text

Using the Items Collection Editor, go to the Image property of a button Here, you can see the Image property of the Cut button, which currently is set to System DrawingBitmap and shows the default image

Click the ellipsis ( ) next to SystemDrawingBitmap This will display the Select Resource dialog box shown here You use this dialog box to assign an image to a form or control in a Windows application

Choose the Local Resource radio button and then click the Import button associated with it This displays the Open dialog box shown next, which you use to browse to and select an image file to be displayed on the button

Visual Studio 2005 includes bitmap files you can use as toolbar images These files are located by default within the directory C:\Program Files\Microsoft Visual Studio 8 \Common7\VS2005ImageLibrary From there I went to the folder bitmaps\ commands\highcolor, shown here As you can see, there are bitmap files (bmp extensions) for Cut, Copy, and (if you scroll further in the dialog box depicted in this screenshot) Paste

N OTE You may not have these bitmap files installed, or they may be installed at a different location, depending on the particular edition you purchased or your installation options Choose the Cut bitmap file for the Cut toolbar button and then click the Open button As shown here, the Select Resource dialog box now contains the image for Cut

Click OK in the Select Resource dialog box As shown here, the Items Collection Editor now shows an image for the Image property of the Cut button

Repeat the same process for the Copy and Paste buttons, except of course choose Copybmp for the Copy button and Pastebmp for the Paste button When you re done, click OK to close the Items Collection Editor Figure 12-6 shows the toolbar, with images for Cut, Copy, and Paste

Figure 12-6

N OTE The size of the bitmap and the size of the toolbar button may be different You can set the ImageScaling property to SizeToFit so the image will size to fit on the toolbar button

The toolbar buttons look prettier now that each has an image on it, but they still don t do anything when they re clicked In this section, we ll write code so the Cut toolbar button provides the same cut action as the Cut menu item and context menu item we worked on in 11 Similarly, when you re finished with this section, the Copy toolbar button will provide the same copy action as the Copy menu item and context menu item, and the Paste toolbar button will provide the same paste action as the Paste menu item and context menu item The Cut, Copy, and Paste methods of the TextBox class also could be called in the Click event procedures of the corresponding toolbar buttons However, as discussed in 11 in connection with context menu items, this would be a duplication of code Here, the duplication is short, but in other circumstances it may not be Therefore, it is useful instead to have each toolbar button s functionality handled by the corresponding Edit main menu item 11, in the section Adding Functionality to Context Menu Items, discussed three different alternatives for having a context menu item s functionality handled by the corresponding main menu item The same discussion applies here to having a toolbar button s functionality handled by the corresponding main menu item To illustrate the use of all three alternatives, the AddHandler alternative is used for the Cut toolbar button, the Handles alternative is used for the Copy toolbar button, and the alternative of calling another event procedure is used for the Paste toolbar button Add the following line of code to the Load event procedure for the form so the Click event procedure of the Edit | Cut menu item handles the Click event of the Cut toolbar button:
