Determine color scheme used by app

[=?Utf-8?B?bGpsZXZlbmQy?=]

I want to determine the Windows color scheme that is being used by my app.
This means that I need to determine the following:

1. Does the OS support themes?
2. Are themes currently enabled within the OS?
3. Are themes currently enabled within the application?
4. If all of the above are true, then what color scheme is being used (e.g.,
Default (blue), Olive Green or Silver if the OS is Windows XP)?

Also, I have not used Windows Vista so any help with the possible color
schemes with that OS would be greatly appreciated.

Thanks for any help!

I want to determine the Windows color scheme that is being used by
my app. This means that I need to determine the following:

1. Does the OS support themes?

System.Windows. Forms.VisualSty les.VisualStyle Information.IsS upportedByOS

2. Are themes currently enabled within the OS?

System.Windows. Forms.VisualSty les.VisualStyle Information.IsE nabledByUser

3. Are themes currently enabled within the application?

System.Windows. Forms.Applicati on.VisualStyleS tate

4. If all of the above are true, then what color scheme is being used
(e.g.,
Default (blue), Olive Green or Silver if the OS is Windows XP)?

System.Windows. Forms.VisualSty les.VisualStyle Information.Col orScheme

Also, I have not used Windows Vista so any help with the possible color
schemes with that OS would be greatly appreciated.

Can't help you with that.

Wow, thank you both so much for the info. That was quick and a lot easier
than I expected.

Just one more question ... is there an event (or some other notification)
when the value of
System.Windows. Forms.VisualSty les.VisualStyle Information.Col orScheme changes?
Of course I could just test the value during a timer's tick event, but I
wanted to see if there is a more efficient technique. I need to know when
VisualStyleInfo rmation.ColorSc heme changes so that I update my custom drawn
controls if the user changes the Windows Color Scheme while my app is running.

Thanks again!

Untested:
Subscribe to Microsoft.Win32 .SystemEvents.U serPreferenceCh anged. In the
handler check

If e.Category = Microsoft.Win32 .UserPreference Category.Visual Style

Hello Lance,

Armin's suggestion is right. UserPreferenceC hanged event is able to capture
the change of system Theme. I did a test for it:

SystemEvents.Us erPreferenceCha nged += new
UserPreferenceC hangedEventHand ler(SystemEvent s_UserPreferenc eChanged);

void SystemEvents_Us erPreferenceCha nged(object sender,
UserPreferenceC hangedEventArgs e)
{
if (e.Category == UserPreferenceC ategory.VisualS tyle)
{
MessageBox.Show ("Changed");
}
}

Then when I change my system's theme from Windows Vista to Windows Classic,
the message box "Changed" is shown.

Thank you, Armin.

Lance, if you have any other concen or need anything else, please feel free
to let us know.

What if the scheme is changed to another theme that the user downloaded?

Hello Rinze,

I did a test on it. The event SystemEvents.Us erPreferenceCha nged is still
able to capture the change of theme.
