VB.NET透明面板

Question

I'm trying to use a transparent panel. I want add a panel to the center of a form. This panel should result in darkness.

How can I add a transparent panel to my form without a background picture?

Answer 1

1)Set the background image of the form to the picture you want as a background and set the background image layout to 'stretch' as shown below.

2)Add a panel control.

3)Size the panel control to cover most of the form.

4)Add the code below to the form load event.

Panel1.BackColor = Color.FromArgb(185, 0, 0, 0)

5)Set form border style to 'none'

6)Add a button to the panel

7)Set the buttons Flat Style, Border Size and Forecolor as shown below.

8)Add the following code to the form load event.

Button1.BackColor = Color.FromArgb(75, 240, 240, 240)

9)Compile and there you go

Note:You can use the same method for other controls on the form but remember that it will only be the background image of the form that shows in any control. In other words, you can't stack controls on top of each other and see the bottom control because the background of the foremost control will be the background image of the form not the control immediately behind it.
