Demonstration of opacity and transparency key for making non rectangular forms

Sample Image - notepad.jpg


This is the sample code to demonstrate the two properties which are provided by visual studio. This project is made using visual studio 2005 that uses dot net framework you should have to download dot net frame work 2 to run this project. In order to use the transparency effect there is a property in visual studio named opacity we can use this property to give the fade out and fade in effect. For making this we use the following code snippet .this code is inserted in form_load.


Dim i As Double

        For i = 0 To 1 Step 0.1


            Me.Opacity = i

            Me.Visible = True



By increasing the sleep value we can increase the delay in the fade effect.


To change the shape of the form we have to change the transparency key to a color which will not match with the color of the image form which we can make by using any graphics tool. I have used adobe CS for this purpose and made a background image for the form.
