C#43;#43;Builder6操作Zlib进行数据压缩

CHUNK， stderr); break; case Z_STREAM_ERROR: fputs(invalid compression level\n，因为是DLL的Zlib貌似不能直接在CB里修改这个利用txt文本打开修改保存再在Cb里运行 8、添加一个button空间输入代码最后出问题问题是 [Linker Error] Unresolved external _deflateInit_ referenced from E:\CBUILDER\SS\UNIT1.OBJ [Linker Error] Unresolved external _deflate referenced from E:\CBUILDER\SS\UNIT1.OBJ [Linker Error] Unresolved external _deflateEnd referenced from E:\CBUILDER\SS\UNIT1.OBJ 我不知道怎么修改了~~~郁闷， 1。

stderr); break; case Z_VERSION_ERROR: fputs(zlib version mismatch!\n， stderr); switch (ret) { case Z_ERRNO: if (ferror(stdin)) fputs(error reading stdin\n， int level) { int ret， Z_DEFAULT_COMPRESSION); // inf(); // int ret; // // /* do compression if no arguments */ // if (argc 1) { //ret def(stdin， MD5 checksum cc7fa97f9c19386bb701acc79d0abbca)” 2、解压缩得到文件夹及文件为include文件夹包括zconf.hzlib.h文件lib文件夹包括zdll.expzdll.libzlib.def文件test文件夹包括example_d.exeminigzip_exetestzlib_d.exeuntgz_d.exe文件以及四个文件DLL_FAQ.txtREADME.txtUSAGE.txt和zlib1.dll文件， 整个Unit1.cpp的源代码如下 //--------------------------------------------------------------------------- #include vcl.h #pragma hdrstop #include Unit1.h #include stdio.h #include string.h #include assert.h #include zlib.h #define CHUNK 16384 //--------------------------------------------------------------------------- #pragma package(smart_init) #pragma resource *.dfm TForm1 *Form1; //--------------------------------------------------------------------------- __fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner) { } //--------------------------------------------------------------------------- /* Compress from file source to file dest until EOF on source. def() returns Z_OK on success， Z_DATA_ERROR if the deflate data is invalid or incomplete。

have， 6、利用Project-Add to Project将“..\Borland\CBuilder6\Lib\Zlib\zlib.lib”文件添加到当前工程中， Z_NO_FLUSH); assert(ret ! Z_STREAM_ERROR); /* state not clobbered */ switch (ret) { case Z_NEED_DICT: ret Z_DATA_ERROR;/* and fall through */ case Z_DATA_ERROR: case Z_MEM_ERROR: (void)inflateEnd(strm); return ret; } have CHUNK - strm.avail_out; if (fwrite(out， have。

zipfile format (79K。

3、利用CBuilder6的implib.exe将步骤2中的zlib1.dll转换为zlib.lib 4、将步骤2中的include文件夹中的zconf.hzlib.h文件放到CB的安装目录“..\CBuilder6\Include\”下自己建立了一个Zlib文件夹存放便于查找即最后的存放目录为“..\CBuilder6\Include\Zlib\zconf.h”以及“..\CBuilder6\Include\Zlib\zlib.h”， source); if (ferror(source)) { (void)inflateEnd(strm); return Z_ERRNO; } if (strm.avail_in 0) break; strm.next_in in; /* run inflate() on input until output buffer not full */ do { strm.avail_out CHUNK; strm.next_out out; ret inflate(strm， Z_STREAM_ERROR if an invalid compression level is supplied， or Z_ERRNO if there is an error reading or writing the files. */ int inf(FILE *source， ， -d) 0) { //ret inf(stdin。

source); if (ferror(source)) { (void)deflateEnd(strm); return Z_ERRNO; } flush feof(source) ? Z_FINISH : Z_NO_FLUSH; strm.next_in in; /* run deflate() on input until output buffer not full， flush); /* no bad return value */ assert(ret ! Z_STREAM_ERROR); /* state not clobbered */ have CHUNK - strm.avail_out; if (fwrite(out， stdout); //if (ret ! Z_OK) //zerr(ret); //return ret; // } // // /* otherwise， Z_MEM_ERROR if memory could not be allocated for processing， stdout， Z_MEM_ERROR if memory could not be allocated for processing， 1， stderr); if (ferror(stdout)) fputs(error writing stdout\n。

将详细步骤贴在下面帖子较长给各位添麻烦了~~~不好意思 1、在网站中下载了Zlib.dll上面提供了四个我下载的是 “zlib compiled DLL， 1， stderr); break; case Z_DATA_ERROR: fputs(invalid or incomplete deflate data\n，同理将步骤3中生成的zlib.lib存放为“..\Borland\CBuilder6\Lib\Zlib\zlib.lib”下。
