在VC程序中改变当前目录

类别:编程语言 点击:0 评论:0 推荐:

PSDK中使用GetCurrentDirectory()SetCurrentDirectory()来改变当前目录,示例如下:
#include <windows.h>
#include <stdio.h>
#include <conio.h>
#include <tchar.h>

#define BUFSIZE MAX_PATH
 
int _tmain(int argc, TCHAR **argv, TCHAR **envp)
{
   TCHAR Buffer[BUFSIZE];
   DWORD dwRet;

   if(argc != 2)
   {
      _tprintf(TEXT("Usage: Test <dir>\n"));
      return 0;
   }

   dwRet = GetCurrentDirectory(BUFSIZE, Buffer);

   if( dwRet == 0 )
   {
      _tprintf(TEXT("GetCurrentDirectory failed (%d)\n"), GetLastError());
      return 0;
   }
   if(dwRet > BUFSIZE)
   {
      _tprintf(TEXT("GetCurrentDirectory failed (buffer too small;need %d chars)\n"), dwRet);
      return 0;
   }
   if( !SetCurrentDirectory(argv[1]))
   {
      _tprintf(TEXT("SetCurrentDirectory failed (%d)\n"),  GetLastError());
      return 0;
   }
   _tprintf(TEXT("Set current directory to %s\n"), argv[1]);

   if( !SetCurrentDirectory(Buffer) )
   {
      _tprintf(TEXT("SetCurrentDirectory failed (%d)\n"),  GetLastError());
      return 0;
   }
   _tprintf(TEXT("Restored previous directory (%s).\n"), Buffer);

   return 1;    
}

本示例用vc6编译连接可行。
