UAC权限问题

[fengqing-maker]

现象:在配置属性->连接器->清单文件->UAC执行级别->修改为requireAdministrator;然后编译生成exe,这时候打开exe是不会提示使用管理员权限。
修改方案:在HexCtrl.h里面注释掉#pragma comment(linker,"/manifestdependency:....),然后重新生成exe,这时候打开exe是会提示使用管理员权限。
问题:1.#pragma comment(linker,"/manifestdependency:...)这行代码是干嘛的?(猜测是控件的style之类的)
2.请问下能否去掉？去掉后有什么影响
3.您当时为什么要加载这一行代码?

Please use English if possible.
If your question was about this line of code: #pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\""), it's a standard Microsoft manifest for modern visual styles.
See here for details.

Thank you for your answer.
What i mean is that it doesn't work when i build project with requireAdministrator.
you can see the picture.

Hmm, frankly saying I don't have an answer to this.
I've tried to set requireAdministrator and it worked fine on my machine. But I have UAC totally disabled, because it's causing more inconvenience than help.
I think it might be a more general Windows related question, and how it correlates with compiler/linker options, than the HexCtrl question.

Basically, if you ask Visual Studio to generate default MFC Dialog based project, you immediately find these lines in yourstdafx.h, or framework.h:

#ifdef _UNICODE
#if defined _M_IX86
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*'\"")
#elif defined _M_X64
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='amd64' publicKeyToken='6595b64144ccf1df' language='*'\"")
#else
#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")
#endif
#endif

So, it's all standard, HexCtrl has nothing special here.
