Code an application to allow you to change text box colours, including a menu, toolbar and short-cut menus

This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.

Before you can do this exercise, you'll need to download and unzip this file .

Add the existing form frmNewHeart into your project from the folder shown above (or use one you already have).

Allow a user to change the colour of each text box, by adding MenuStrip, ToolStrip, StatusStrip and ContextMenu controls (you may find the property shown below useful):

Visual Basic 2010 exercise - Menus and toolbars (image 1)

You can change the colour of a textbox using the menu, toolbar or short-cut menu

Here's what the Colour menu would look like for this example (the Red option is disabled, as this is the colour selected):

Visual Basic 2010 exercise - Menus and toolbars (image 2)

The chosen menu option is checked, but not enabled

You may find it useful to write the following property of the form, so that you can find out which the currently selected textbox is (note that if the user is not on a text box, this routine will return Nothing - which you can test for):

Visual Basic 2010 exercise - Menus and toolbars (image 3)

The TRYCAST function will attempt to convert the control into a textbox, and return NOTHING if this is not possible

Test that your application works, then close the form down.

You can unzip this file to see the answers to this exercise, although please remember this is for your personal use only.
