Converting to XP Common Controls

How do I give my app the new XP look but still keep it 100% backwards compatible back to Windows 95?

I believe there is a new COMCTL DLL that needs to be linked to - any info or links to articles on this would be appreciated.

How do I make sure that the app doesn't meltdown if the new DLL is not available (ie for pre-XP versions) ?

In summary, to enable visual styles you must:
1) Link to comctl32.lib/dll and call InitCommonControls[Ex]()
2) Add a "manifest" (either as a file called "filename.exe.manifest" or better still as a resource ID=1 TYPE=24.

To help you add a manifest heres is my resource template I use with VisualC6
http://www.brightnova.com/downloads/misc/Manifest.rct
save this file to C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Template
Now restart VC6, load a project and choose Insert | Resource... select the item [24]->[1] as the resource type and click New.

This will create a default "manifest.XML" file in your project directory that gets compiled into your EXE. (For some strange reason VC shows it as binary, but its really plain XML text.)

Thats it!

Just tried it and it works a treat - thanks again.

The only thing I've noticed is that it doesn't affect buttons with the BS_ICON style set, these still appear as in Win 95 -> 2K.  Any ideas?

Its a known limitation.

For non plain text buttons you need to do much of the drawing yourself using functions like OpenThemeData/DrawThemeEdge etc
E.g.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/CommCtls/Userex/functions/closethemedata.asp

Of course you need to be careful how you link to such functions because they don't exist on anything but WinXP!
