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.VisualStyles.VisualStyleInfor mation.IsSupportedByOS

2. Are themes currently enabled within the OS?

System.Windows.Forms.VisualStyles.VisualStyleInfor mation.IsEnabledByUser

3. Are themes currently enabled within the application?

System.Windows.Forms.Application.VisualStyleState

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.VisualStyles.VisualStyleInfor mation.ColorScheme

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.VisualStyles.VisualStyleInfor mation.ColorScheme 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
VisualStyleInformation.ColorScheme 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.UserPreferenceChanged . In the
handler check

If e.Category = Microsoft.Win32.UserPreferenceCategory.VisualStyle

Hello Lance,

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

SystemEvents.UserPreferenceChanged += new
UserPreferenceChangedEventHandler(SystemEvents_Use rPreferenceChanged);

void SystemEvents_UserPreferenceChanged(object sender,
UserPreferenceChangedEventArgs e)
{
if (e.Category == UserPreferenceCategory.VisualStyle)
{
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.UserPreferenceChanged is still
able to capture the change of theme.
