VC++中使用Zlib的一個例子

首先到www.zlib.net
下載個ZLIB,解壓縮後開啟zlib-1.2.3/projects/visualc6/zlib.dsw

選擇Win32 LIB Release 按F7編繹產生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

然後

#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中文測試 中文測試/
aaaaa bbbbb ccccc ddddd aaaaa bbbbb ccccc ddddd中文測試 中文測試/
aaaaa bbbbb ccccc ddddd aaaaa bbbbb ccccc ddddd中文測試 中文測試/
aaaaa bbbbb ccccc ddddd aaaaa bbbbb ccccc ddddd中文測試 中文測試";

     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);
}
