Visual Basic | Menus and toolbars exercise | Create a toolbar and menu system
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.
The answer to the exercise will be included and explained if you attend the relevant Wise Owl course (sadly, only in the UK for now).
You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
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):
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):
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):
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.
