选择Win32 LIB Release 按F7编绎生成zlib.lib

首先到www.zlib.net 下载个ZLIB,解压缩后打开zlib-1.2.3\projects\visualc6\zlib.dsw

选择Win32 LIB Release 按F7编绎生成zlib.lib

工程中使用时把

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

拷贝到所在工程目录下

然后

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

void CZlibTestDlg::OnButton1()
{
const unsigned char strSrc[]="hello world!\n\
aaaaa bbbbb ccccc ddddd aaaaa bbbbb ccccc ddddd中文测试 中文测试\
aaaaa bbbbb ccccc ddddd aaaaa bbbbb ccccc ddddd中文测试 中文测试\
aaaaa bbbbb ccccc ddddd aaaaa bbbbb ccccc ddddd中文测试 中文测试\
aaaaa bbbbb ccccc ddddd aaaaa bbbbb ccccc ddddd中文测试 中文测试";

     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);
     //压缩
      compress(buff,&bufLen,strSrc,srcLen);
      strc2.Format("\nAfter Compressed Length:%d\nCompressed String:%s\n==============\n",bufLen,buff);
        
     //解压缩
      uncompress(strDst,&dstLen,buff,bufLen);
      strc3.Format("\nAfter UnCompressed Length:%d\nUnCompressed String:%s\n",dstLen,strDst);
     
   AfxMessageBox(strc+strc2+strc3);
}
