now I use java gzip to compress a file. and I want to use gunzip of Crptlib to decompress it. but when I use like below ,there are some errors in funcion processheader(), DecodeHeader();,etc. But I use winrar tool to decompress it correctly . the file is binary file. thanks
decText contains the file (to be decompressed)'s all bytes. I use CFile's Read method to read.
1 CFile myfile("F:\\aa.000.zip", CFile::modeRead);
2 int length = myfile.getLength();
3 byte * decText = new byte[length];
4 myfile.Read(decText,length);
5 Gunzip unzipper;
6 unzipper.Put((const unsigned char*)decText,length);
7 unzipper.Close();
8 long uLen1 = unzipper.MaxRetrieveable();
9 byte* pUncompressed1 = new byte[(int)uLen1];
10 unzipper.Get(pUncompressed1, uLen1);
6 unzipper.Put((const unsigned char*)decText,length);
7 unzipper.Close();
8 long uLen1 = unzipper.MaxRetrieveable();
9 byte* pUncompressed1 = new byte[(int)uLen1];
10 unzipper.Get(pUncompressed1, uLen1);
when run the line 6. there will be errors . kenerl.dll etc. I want to know that is why . thanks how to use it correctly ? but when I use gzip to compress a string ,then use gunzip to decompress it . It is ok .when use it to a file. it is wrong . I am looking forward to your reply. thanks .
