SDK程序问题

一个SDK关机程序，但是显示一直不对，请高手赐教。

//关机.cpp
#include <windows.h>
#include <iostream>
#include "resource.h"
#include <commctrl.h>//注意这个头文件，要想使用扩展的一些控件就要用这个头文件
#pragma comment(lib,"comctl32.lib")//编译时增加comctl32.lib，里面有扩展控件的接口。

// Get a token for this process.

if (!OpenProcessToken(GetCurrentProcess(),
TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
return( FALSE );

// Get the LUID for the shutdown privilege.

LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,
&tkp.Privileges[0].Luid);

tkp.PrivilegeCount = 1; // one privilege to set
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

// Get the shutdown privilege for this process.

AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,
(PTOKEN_PRIVILEGES)NULL, 0);

if (GetLastError() != ERROR_SUCCESS)
return FALSE;

}

想问一下显示当前时间的静态框为何不会显示了，还请高手能把程序改对，还有为什么对话框左上角的图标一直不显示。请高手详细解答一下。谢谢了。
