Windows forms mnemonics

The buttons you see in most commercially available applications usually use Mnemonics and have short cut keys, so this will hit close to home and should be pretty easily understood by all, from the rookie programmer to some of the more experienced developers out there.

Make sure to add a reference to the System. Imports System. Public Class MyBasicButton. Inherits System. PaintBorderAndText g. OnPaint e. End Sub. Dim rect as New Rectangle 0, 0, Me. Width — 1, Me. Height — 1. Dim rectf as New RectangleF 0, 0, Me. Width, Me.

The following code example demonstrates an extension of the button class that overrides the ProcessMnemonic method to exhibit custom behavior. The example also demonstrates the use of the CanSelect and IsMnemonic properties. To run this example, paste the following code after a form class, in the same file. The control also has a caption with a mnemonic character specified. The example code uses the PreferredHeight and PreferredWidth properties to properly size the Label control on the form on which it is displayed.

This example requires that an ImageList has been created and named imageList1 and that it has loaded two images. The example also requires that the code is within a form that has the System. Drawing namespace added to its code.

It worked but just for one time. The mnemonic only applies to the control it is set on - so Alt-r will only move you from the "Reset" label to the "nothing" label assuming you made it a SelectableLabel - after pressing alt-r, pressing alt-r multiple times will appear to have no effect because you keep moving to the "nothing" label where you already are.

The mnemonics work slightly differently for the different types of control - see Hans Passant's comment above that the Label mnemonic was designed to be paired with another selectable control immediately following so if you had a label next to a textbox in tab index order the mnemonic would move you to that control.

With the button, the effect of the mnemonic is to cause a Click event - BUT the focus does not move from where it currently is. Ok I can fix that with a button. Focus ; after the textbox.
