Create colorful Command Buttons

Create colorful Command Buttons

The VB CommandButton control supports neither the ForeColor nor the BackColor properties. If you want to create colorful buttons without resorting to 3rd party controls, you can use an OptionButton control with the Style property set to 1-Graphical. Such OptionButton controls appear to be very similar to regular CommandButton controls, but they let you modify their foreground and background colors. To have them behave as CommandButton controls you only have to add the following line of code in their Click event procedure:

Private Sub Option1_Click()    ' reset the value to False, so that the    ' control doesn't appear to be depressed    Option1.Value = False    ' here you insert the code that you want    ' to execute when the button is clicked    ' ....End Sub

One problem with this simple approach is that the border of this “fake” CommandButton control doesn’t change its appearance when the control has the focus. Another problem is that you can’t easily make this button the default button on the form, unless you trap the Enter key with a form-level keyboard handler (that is, you set KeyPreview = True).

You can solve both problems using a real CommandButton control and place it “behind” the colorful OptionButton control. This will provide the desidered border (without having to draw it yourself) and if the Default property of such a button is set to Default, it will work as expected.

The following code excerpt shows how you can do the trick. It assumes that Option1 is the colorful OptionButton control, and Command1 is the hidden CommandButton control:
