You want to include visual styles by adding a manifest dependency to general assembly 6 in the application manifest.
If you are using DevStudio, this should be as simple as adding the #pragma directive from the linked page:
#pragma comment(linker,"\"/manifestdependency:type='win32'
name='Microsoft.Windows.Common-Controls'
version='6.0.0.0' processorArchitecture='*'
publicKeyToken='6595b64144ccf1df' language='*'\"")
