Hi David,

Okay, I have an app I'm developing in rather a convoluted setup: I'm
using VPC to develop it on a Windows 2003 machine from my XP laptop.

So far so good. But when I try to run the application on XP or Vista, my
listview headers still appear in the same old gray, 3D look.

I assume this is related to the manifest, and that there are manifests
for XP and Vista, but how do I make it look current on Windows 2003, XP,
Vista, Windows 7, and beyond? (And why isn't that the default?)

Do I need to create the manifest by hand? Does anyone have a good
understanding of this?

When you create a new MFC project in VC2005, it generates stdafx.h with
these lines at the bottom of it:

Okay, this is actually a Win32 app and not MFC. My stdafx.h file has nothing
below the includes. I'm really not clear on why it was assumed this was
needed for MFC apps but not Win32 apps.

The other thing you must make sure of doing is in your
CDerivedApp::InitInstance():

I'll have to dig through that and see what it does I suppose.

// InitCommonControlsEx() is required on Windows XP if an application
// manifest specifies use of ComCtl32.dll version 6 or later to enable
// visual styles. Otherwise, any window creation will fail.
INITCOMMONCONTROLSEX InitCtrls;
InitCtrls.dwSize = sizeof(InitCtrls);
// Set this to include all the common control classes you want to use
// in your application.
InitCtrls.dwICC = ICC_WIN95_CLASSES;
InitCommonControlsEx(&InitCtrls);

Visual Studio included this code automatically when I created the project.

I guess I'll study CWinApp::InitInstance() and the stuff placed in stdafx.h
in an MFC app.

Thanks.

Jonathan
