And the rest of my application *does* "look like Windows XP" (so I am using the Windows XP Qt style).

Off-list, 程梁 found two problems with my suggestion.  Correcting them
let him get the new dialog style in his program..

1. The MSDN page I linked to doesn't show a complete example of the
needed XML file, just a partial one.

2. I used a sample file name of example.com.manifest.  But it should
have been example.exe.manifest.

Instead of looking at the MSDN page for an example manifest file, you
can use the mt.exe tool (from Microsoft's free Windows SDK) to extract a
working manifest file from an existing program.  For example, you can
extract the manifest from notepad.exe with

    mt.exe -inputresource:\windows\notepad.exe;#1 -out:extracted.manifest

The result is this manifest file:


    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <assembly xmlns="urn:schemas-microsoft-com:asm.v1"
    manifestVersion="1.0">
    <assemblyIdentity name="Microsoft.Windows.Shell.notepad"
    processorArchitecture="x86" version="5.1.0.0"
    type="win32"></assemblyIdentity>
    <description>Windows Shell</description>
    <dependency>
        <dependentAssembly>
            <assemblyIdentity type="win32"
    name="Microsoft.Windows.Common-Controls" version="6.0.0.0"
    processorArchitecture="x86" publicKeyToken="6595b64144ccf1df"
    language="*"></assemblyIdentity>
        </dependentAssembly>
    </dependency>
    </assembly>

Change "Microsoft.Windows.Shell.notepad" to your program's name, and
"Windows Shell" to its description, then rename the file to match your
executable, and you should get a matching common dialog style when you
run it.
