Message Box in Metro Style XP, W7 and W8

Question

Let's get straight to the point, a time'm implementing a Message Box in Metro Style with Windows Forms and C # implementation was cool, but I'm having problems with semi transparent background on windows XP, use the method:

this.BackColor = Color.FromArgb (0x46, 0x69, 0x69, 0x69);

This model worked perfectly on windows 7 and 8 on XP but not also renders simply ignores the parameter Alpha. and beyond it depending on the system model theme he does not respond to Alpha too.

Even after searching I did not find something that really works perfectly in this Annex I developed a model based on other examples, to work on Windows XP, 7 and 8, the background is semi transparent independent of themes but does not render the controls inside the form of message simply ignores all content.

Hope you can give me a help.

Thank you in advance.

Ok, What I want and create a message box in Windows 8 Metro style but the semi transparent background is not compatible with versions of Windows XP, Windows 7 and Windows 8, the transparency is simply ignored, with the example model could reach a standard that maintains the appearance but it ignores the controls within the form.

Only Top-Level windows (Forms) support alpha transparence in Winforms, but not controls. If you want to have semi-transparent controls in Winforms you'll have to implement that feature by yourself.

See this post as an example: Winforms: Making a control transparent

Edit: If you want a transparent / semi-transparent MessageBox, you have to create it yourself. Simply inherit from Form (which supports transparency) and create the look and feel that you want to have. Then you can simply set the opacity of 'your' MessageBox:

myMessageBox.Opacity = .75;

If you want more control over the appearance of your controls you should consider using WPF. Here is a WPF-controll that seems to fit your needs:

Thank you, Not like semi-transparent controls, I would just like the bottom of the form semi-transparent as well as message boxes in windows 8. – Paulo Rodrigo Martins Dec 16 '13 at 11:19
See the examples in the link: http://sdrv.ms/18tQn3X Would the same result in windows XP, 7, 8 – Paulo Rodrigo Martins Dec 16 '13 at 11:23
Regarding the messagebox I have edited my post. Simply create your own with inheriting from Form. But what do you mean with just the bottom of your form semi-transparent? – user1567896 Dec 16 '13 at 11:39
Yes only the background should be semi transparent, as in the example images. thanks for attention. – Paulo Rodrigo Martins Dec 16 '13 at 11:46
You can see an example in (sdrv.ms/18tQn3X) check images and design style. – Paulo Rodrigo Martins Dec 16 '13 at 11:52
I think that would be easy with WPF but very very very tricky with Winforms. I can not think of any good solution. – user1567896 Dec 16 '13 at 11:57
I do not have experience in WPF, you think he will behave perfectly on windows XP? – Paulo Rodrigo Martins Dec 16 '13 at 12:02
WPF is much more flexible with control-configuration than Winforms. Take a look at this: http://www.codeproject.com/Tips/619333/All-Purpose-Message-Box-in-WPF This seem to be what you are looking for. You can also mix Winforms and WPF. But you have to google that yourself as I have no experience with mixing WPF and Winforms myself. – user1567896 Dec 16 '13 at 12:18
Ok thanks for the help, I will continue my fight to solve the problem. – Paulo Rodrigo Martins Dec 16 '13 at 12:32
