各位老大，我刚刚接触D语言没多久，DMD自带例子中有一个winsamp.d的程序，编译后能够正常运行，想让界面看起来跟XP一样，就创建了一个winsamp.exe.manifest文件，再次运行这个示例程序，按钮就不见了，各位前辈们能帮忙看看是什么问题么？

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