Using .NET 1.1, I need to be able to detect if Themes are enabled or
disabled, not for a specific application, but for the system as a whole (ie.
the current user). The reason I need to be able to do this is because of
this bug in MFC http://support.microsoft.com/?kbid=319740, which is used to
build a component I am in turn making use of. So, I need to detect if
Themes are running and if so, see if the correct version of uxtheme.dll is
installed, else disallow a certain operation.
Any hints? 6  1973 
I solved this using the code below, I hope it's more or less correct:
Dim myVersion As Version =
OSFeature.Featu re.GetVersionPr esent(OSFeature .Themes)
If not myVersion Is Nothing Then
Return True
Else
Return False
End If

Fred,
That is a good method.

Hi Fred,
You can use UxTheme's IsThemActive() API, available in Windows XP (NT 5.1)
and later.
<System.Runtime .InteropService s.DllImport("Ux Theme")> _
Public Shared Function IsThemeActive() as Boolean
End Function
After the P/Invoke function is defined in the appropriate scope, you can
call it provided that the Operating System's version is at least Windows XP:
Dim fThemesActive As Boolean = False
If Environment.OSV ersion.Version >= New Version(5, 1) Then
fThemesActive = IsThemeActive()
End If

To continue this conversation with myself, the above didn't work, because it
checks to see if the feature is present, not whether or not it is currently
switched on/off. I am still looking for a way to see if the user is using a
Theme (other than the stock "Classic Windows", which isn't really a Theme,
it's more the way things were before MS botched up it's themes
implementation) .

Hi,
I'm trying to detect if XP themes are enabled or not in code. This not as
easy as it seams, however. I thought Application.VisualStyleState would be
of a lot of help, but unfortunately, it was not.
Basically, I need something similar to this:
If LegacyOS Then 'W2K, W98, WME
return False

Hi,
I searched around everywhere on the net, but could not find a simple example
of detecting if cookies are enabled - on server side, and without moving
from one page to another.
This should be a very basic functionality, so I am reluctant to believe that
there's no way to simply test it in a server-side script.
Anyone?
Thx,
Agoston

Hi,
I was going to ask a question, but I think I've answered it so now I am
going to rant about how crappy ASP.NET themes are instead.
As I've indicated above, my problem today is with themes. Per
microsoft "Only one theme can be applied to each page. You cannot apply
multiple themes to a page, unlike style sheets where multiple style
sheets can be applied."

I have theming enabled and have two themes for my web site (hence two

But I need the styles to be applied whilst developing in the IDE.
I cannot see the styles (styles not applied to the HTML) in the page unless
and untill I set the styleSheetTheme attribute in the page directive.
I.e. if I set the styleSheetTheme in the web.config, this doesn't make any
difference in the IDE, but is applied...

What I would like to do is verify that they have it enabled, if they do not, then send them to another page that would walk them through how to enable it.
I'm already doing this to verify their browser, if...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
