VC++中使用Zlib的一个例子

来源：互联网发布：错生网络剧在线播放编辑：程序博客网时间：2024/05/08 15:18

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);
}
