  printf ("Microsoft Win32s ");
  break;
 }
 return TRUE; 
}
   int main()
{
 DisplaySystemVersion();
}

   3.更改系统日期格式

char buff[]="yyyy-MM-dd";
SetLocaleInfo(LOCALE_SYSTEM_DEFAULT,LOCALE_SSHORTDATE ,buff);

   4.检测电脑最后一次输入
切换到: 纯代码

切换到: 纯代码  
   
#include "stdio.h"
#include "string.h"
#define TBYTE unsigned char
   void FirstLetter(int nCode, char& strRet);
void GetFirstLetter(char* strName, char* strFirstLetter)
{
    TBYTE ucHigh, ucLow;
    int  nCode;
    char strRet;
 memset(strFirstLetter, 0, sizeof(strFirstLetter));
 int i;
 int len = 0;
    for (i=0; i < (int)strlen(strName); i++)
    {
        if ((TBYTE)strName[i] < 0x80)
            continue;
  
        ucHigh = (TBYTE)strName[i];
        ucLow  = (TBYTE)strName[i+1];
        if ( ucHigh < 0xa1 || ucLow < 0xa1)
            continue;
        else
            // Treat code by section-position as an int type parameter,
            // so make following change to nCode.
            nCode = (ucHigh - 0xa0) * 100 + ucLow - 0xa0;
  
        FirstLetter(nCode, strRet);
  strFirstLetter[len] = strRet;
        i++;
  len++;
    }
 strFirstLetter[len] = 0;
}
   void FirstLetter(int nCode, char& strLetter)
{
 if(nCode >= 1601 && nCode < 1637) strLetter = 'A';
 if(nCode >= 1637 && nCode < 1833) strLetter = 'B';
 if(nCode >= 1833 && nCode < 2078) strLetter = 'C';
 if(nCode >= 2078 && nCode < 2274) strLetter = 'D';
 if(nCode >= 2274 && nCode < 2302) strLetter = 'E';
 if(nCode >= 2302 && nCode < 2433) strLetter = 'F';
 if(nCode >= 2433 && nCode < 2594) strLetter = 'G';
 if(nCode >= 2594 && nCode < 2787) strLetter = 'H';
 if(nCode >= 2787 && nCode < 3106) strLetter = 'J';
 if(nCode >= 3106 && nCode < 3212) strLetter = 'K';
 if(nCode >= 3212 && nCode < 3472) strLetter = 'L';
 if(nCode >= 3472 && nCode < 3635) strLetter = 'M';
 if(nCode >= 3635 && nCode < 3722) strLetter = 'N';
 if(nCode >= 3722 && nCode < 3730) strLetter = 'O';
 if(nCode >= 3730 && nCode < 3858) strLetter = 'P';
 if(nCode >= 3858 && nCode < 4027) strLetter = 'Q';
 if(nCode >= 4027 && nCode < 4086) strLetter = 'R';
 if(nCode >= 4086 && nCode < 4390) strLetter = 'S';
 if(nCode >= 4390 && nCode < 4558) strLetter = 'T';
 if(nCode >= 4558 && nCode < 4684) strLetter = 'W';
 if(nCode >= 4684 && nCode < 4925) strLetter = 'X';
 if(nCode >= 4925 && nCode < 5249) strLetter = 'Y';
 if(nCode >= 5249 && nCode < 5590) strLetter = 'Z';
}
   void main()
{
 char strName[10], strRes[5];
    strcpy(strName, "汗!瀑布汗!");
 memset(strRes, 0, sizeof(strRes));
    GetFirstLetter(strName, strRes);
 printf("%s/n", strRes);
}

   6.消除窗口子控件在窗体大小改变时的闪烁
在create窗口的时候类型加上WS_CLIPCHILDREN
   7.读取大于2G的文件
切换到: 纯代码  
   
__int64 myFileSeek (HANDLE hf, __int64 distance, DWORD MoveMethod)
{
   LARGE_INTEGER li;
   li.QuadPart = distance;
   li.LowPart = SetFilePointer (hf, 
                                li.LowPart, 
                                &li.HighPart, 
                                MoveMethod);
   if (li.LowPart == INVALID_SET_FILE_POINTER && GetLastError() 
       != NO_ERROR)
   {
      li.QuadPart = -1;
   }
   return li.QuadPart;
}

   8.操作控制台
GetConsoleScreenBufferInfo 
 返回窗口大小、屏幕缓冲区大小和颜色属性 
 
切换到: 纯代码  
   
SetConsoleWindowInfo 

 改变控制台窗口的大小 
 
SetConsoleScreenBufferSize 
 该表控制台屏幕缓冲区的大小 
 
SetConsoleTextAttribute 
 设置颜色属性 
 
SetConsoleTitle 
 设置控制台窗口的标题 
 
GetConsoleTitle 
 获得控制窗口的标题 

   进程可以使用 FreeConsole 函数来分离继承的控制台或通过 AllocConsole 创建的控制台。
   9.清空回收站
切换到: 纯代码  
   
SHEmptyRecycleBin(NULL, NULL,SHERB_NOCONFIRMATION |SHERB_NOPROGRESSUI | SHERB_NOSOUND);

   10.获得一段时间内cpu的晶振次数
在Intel   Pentium以上级别的CPU中,有一个称为“时间戳(Time   Stamp)”的部件,它以64位无符号整型数的格式,记录了自CPU上电以来所经过的时钟周期数。
切换到: 纯代码  
   
inline   unsigned   __int64   GetCycleCount()   
{   
    __asm   RDTSC   
}

   11.提高应用程序权限
windows应用程序好像不能提高自身的权限,但它有一个未公开的函数:CreateProcessWithLogonW,它可以用administrator身份运行一个进程
CreateProcessWithLogonW API的定义如下:
切换到: 纯代码  
   
BOOL CreateProcessWithLogonW(
LPCWSTR , // 用户乙的账号(Account)
LPCWSTR , //用户乙的域(Domain)
LPCWSTR , // 用户乙的密码(Password)
DWORD , // logon option
LPCWSTR , // executable module name
LPWSTR , // command-line string
DWORD , // creation flags
LPVOID , // new environment block
LPCWSTR , // current directory name
LPSTARTUPINFOW , // startup information
LPPROCESS_INFORMATION // process information

);
另外,你也可用命令行的:runas
如:   
切换到: 纯代码  
   
  runas   /env   /user:user@domain.microsoft.com   "notepad   /"my   file.txt/""

   =================================================================

   12.枚举一个进程中已经打开的文件句柄
调用ntdll.dll的微软没有公布的函数
切换到: 纯代码  
   
DWORD NtQuerySystemInformation( DWORD dwRecordType,

                 PDWORD pdwHandleList,
                 DWORD dwNumBytes,
                 PDWORD pdwNumBytesRet );
   可以返回所有的句柄表,然后根据句柄类型过滤出文件句柄
1 NtQuerySystemInformation
2 NtQueryObject
