首先到www.zlib.net下載個ZLIB,解壓縮后打開zlib-1.2.3\projects\visualc6\zlib.dsw

選擇Win32 LIB Release 按F7編繹生成zlib.lib

工程中使用時把

D:\zlib-1.2.3\projects\visualc6\Win32_LIB_Release\zlib.lib

D:\zlib-1.2.3\zlib.h

D:\zlib-1.2.3\zconf.h

拷貝到所在工程目錄下

然后

#include "zlib.h"
#pragma comment(lib,"zlib.lib")

     unsigned char buff[1024]={0},strDst[1024]={0};
     unsigned long srcLen=sizeof(strSrc),bufLen=sizeof(buff),dstLen=sizeof(strDst);
CString strc,strc2,strc3;
     strc.Format("Src string:%s\nLength:%d\n===================\n",strSrc,srcLen);
     //壓縮
      compress(buff,&bufLen,strSrc,srcLen);
      strc2.Format("\nAfter Compressed Length:%d\nCompressed String:%s\n==============\n",bufLen,buff);
     //解壓縮
      uncompress(strDst,&dstLen,buff,bufLen);
      strc3.Format("\nAfter UnCompressed Length:%d\nUnCompressed String:%s\n",dstLen,strDst);
   AfxMessageBox(strc+strc2+strc3);
