opacity of program

[cdoverlaw]

Hi, i started off in Visual Basic 6 in september at college and i have progressed fast and have moved onto visual basic .net, anyway i want some sample code to look at which changes the opacity of the program.

I want it to use a combo box with different default opacity values and the option to enter other value, i then want the user to then click apply,

I know i may sound thick asking this question but i am only new so dont be to harsh on me

Set the Opacity property of the form to do it. Only works in Windows 2000 and up.

I know that but i cant get my subroutine to work so can someone send me a project to jon@rawserve.com which does what i want it to so that i can look at the code and see where i am going wrong

You need to make sure the value is between 0 and 1. For example, 0.5 is 50% opacity.

OK here is my code for the subroutine i have at the moment

 

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Form1.Opacity = 0.5

End Sub

 

I get the build task error of

C:\Documents and Settings\Jonathan.N-FORCE\My Documents\Visual Studio Projects\Opacity\Form1.vb(59): Reference to a non-shared member requires an object reference.

You can't call a form like that. You need to reference the class instance, not the class itself. Do it like this:

Me.Opacity = 0.5

I dont understand, please can you explain what i need to do, i am only new to visual basic.net and am a fast learner,

[Volte]

I just told you. Use

Me.Opacity = 0.5

You had the right idea before, you just weren't referencing the form correctly.

cool, thanks, also how do i execute another program from within a visual basic program

[mutant]

System.Diagnostics.Process.Start("path to the exe")

The process class will let you start and control processes. If you want more options then create a new Process object instead of using the shared method to start the app.

also how how do i make a trackbar control the opacity, what code is required, (i have never used a trackbar before)
