我正在尝试使用XZip库压缩文件夹。我有一个TCHAR
变量数组,filename
,它包含我想要压缩的文件夹的目录,其中filename
被设置为L"C:\Users\ttyler\Desktop\Software\Folder2\NewFolder\"
。
XZip库说要将XZip.h
文件和XZip.cpp
文件添加到项目中,所以我这样做了。我将#include "XZip.h"
添加到我的项目文件中,然后使用XZip库中的CreateZipZ()
函数,该函数用于创建zip归档文件(按名称):Ex:
CreateZipZ("c:\test.zip", 0, ZIP_FILENAME)
但是我得到这些错误:
'initializing':无法从'initializer list'转换为'HZIP'
我的代码如下所示:参数类型为" char *"与"DWORD">
类型的参数不兼容
#include "XZip.h"
HZIP CreateZipZ(void* z, unsigned int len, DWORD flags);
TCHAR filename[200]; // The directory is saved in this array: "C:\Users\ttyler\Desktop\Software\Folder2\NewFolder\"
CreateZipZ(L"C:\Users\ttyler\Desktop\Folder2", 0, filename_buff5);
示例来自XZip库:
CreateZipZ("c:\test.zip", 0, ZIP_FILENAME)
为什么要在代码中重新声明CreateZipZ()
?它已经在XZip.h
中为您声明了。
关于第一个错误-没有"初始化列表";在代码中显示。显示的代码是在函数内执行,还是在全局范围内执行?我怀疑是后者,这行不通。
关于第二个错误- CreateZipZ()
的第三个参数是DWORD flags
,它描述了如何解释第一个参数void *z
(其中ZIP_FILENAME
在XZip.h
中被声明为2
)。那么,为什么你试图传递一个文件名缓冲区,其中一个数字是预期的?
我认为你没有阅读XZip.h
中的文档。如果您有,您将看到在您的任务中使用此库的正确方法是在第一个参数中使用destination zip文件名调用CreateZip()
(没有后跟Z
),然后为要添加到zip中的文件/文件夹调用ZipAdd()
。XZip.h
中提供了CreateZip()
和ZipAdd()
的文档和示例,例如:
///////////////////////////////////////////////////////////////////////////////
//
// CreateZip()
//
// Purpose: Create a zip archive file
//
// Parameters: z - archive file name if flags is ZIP_FILENAME; for other
// uses see below
// len - for memory (ZIP_MEMORY) should be the buffer size;
// for other uses, should be 0
// flags - indicates usage, see below; for files, this will be
// ZIP_FILENAME
//
// Returns: HZIP - non-zero if zip archive created ok, otherwise 0
//
HZIP CreateZip(void *z, unsigned int len, DWORD flags);
// CreateZip - call this to start the creation of a zip file.
// As the zip is being created, it will be stored somewhere:
// to a pipe: CreateZip(hpipe_write, 0,ZIP_HANDLE);
// in a file (by handle): CreateZip(hfile, 0,ZIP_HANDLE);
// in a file (by name): CreateZip("c:\test.zip", 0,ZIP_FILENAME);
// in memory: CreateZip(buf, len,ZIP_MEMORY);
// or in pagefile memory: CreateZip(0, len,ZIP_MEMORY);
// The final case stores it in memory backed by the system paging file,
// where the zip may not exceed len bytes. This is a bit friendlier than
// allocating memory with new[]: it won't lead to fragmentation, and the
// memory won't be touched unless needed.
// Note: because pipes don't allow random access, the structure of a zipfile
// created into a pipe is slightly different from that created into a file
// or memory. In particular, the compressed-size of the item cannot be
// stored in the zipfile until after the item itself. (Also, for an item added
// itself via a pipe, the uncompressed-size might not either be known until
// after.) This is not normally a problem. But if you try to unzip via a pipe
// as well, then the unzipper will not know these things about the item until
// after it has been unzipped. Therefore: for unzippers which don't just write
// each item to disk or to a pipe, but instead pre-allocate memory space into
// which to unzip them, then either you have to create the zip not to a pipe,
// or you have to add items not from a pipe, or at least when adding items
// from a pipe you have to specify the length.
///////////////////////////////////////////////////////////////////////////////
//
// ZipAdd()
//
// Purpose: Add a file to a zip archive
//
// Parameters: hz - handle to an open zip archive
// dstzn - name used inside the zip archive to identify the file
// src - for a file (ZIP_FILENAME) this specifies the filename
// to be added to the archive; for other uses, see below
// len - for memory (ZIP_MEMORY) this specifies the buffer
// length; for other uses, this should be 0
// flags - indicates usage, see below; for files, this will be
// ZIP_FILENAME
//
// Returns: ZRESULT - ZR_OK if success, otherwise some other value
//
ZRESULT ZipAdd(HZIP hz, const TCHAR *dstzn, void *src, unsigned int len, DWORD flags);
// ZipAdd - call this for each file to be added to the zip.
// dstzn is the name that the file will be stored as in the zip file.
// The file to be added to the zip can come
// from a pipe: ZipAdd(hz,"file.dat", hpipe_read,0,ZIP_HANDLE);
// from a file: ZipAdd(hz,"file.dat", hfile,0,ZIP_HANDLE);
// from a fname: ZipAdd(hz,"file.dat", "c:\docs\origfile.dat",0,ZIP_FILENAME);
// from memory: ZipAdd(hz,"subdir\file.dat", buf,len,ZIP_MEMORY);
// (folder): ZipAdd(hz,"subdir", 0,0,ZIP_FOLDER);
// Note: if adding an item from a pipe, and if also creating the zip file itself
// to a pipe, then you might wish to pass a non-zero length to the ZipAdd
// function. This will let the zipfile store the items size ahead of the
// compressed item itself, which in turn makes it easier when unzipping the
// zipfile into a pipe.
///////////////////////////////////////////////////////////////////////////////
//
// CloseZip()
//
// Purpose: Close an open zip archive
//
// Parameters: hz - handle to an open zip archive
//
// Returns: ZRESULT - ZR_OK if success, otherwise some other value
//
ZRESULT CloseZip(HZIP hz);
// CloseZip - the zip handle must be closed with this function.
// e.g.
//
// (1) Traditional use, creating a zipfile from existing files
// HZIP hz = CreateZip("c:\temp.zip",0,ZIP_FILENAME);
// ZipAdd(hz,"src1.txt", "c:\src1.txt",0,ZIP_FILENAME);
// ZipAdd(hz,"src2.bmp", "c:\src2_origfn.bmp",0,ZIP_FILENAME);
// CloseZip(hz);
//
// (2) Memory use, creating an auto-allocated mem-based zip file from various sources
// HZIP hz = CreateZip(0,100000,ZIP_MEMORY);
// // adding a conventional file...
// ZipAdd(hz,"src1.txt", "c:\src1.txt",0,ZIP_FILENAME);
// // adding something from memory...
// char buf[1000]; for (int i=0; i<1000; i++) buf[i]=(char)(i&0x7F);
// ZipAdd(hz,"file.dat", buf,1000,ZIP_MEMORY);
// // adding something from a pipe...
// HANDLE hread,hwrite; CreatePipe(&hread,&write,NULL,0);
// HANDLE hthread = CreateThread(ThreadFunc,(void*)hwrite);
// ZipAdd(hz,"unz3.dat", hread,0,ZIP_HANDLE);
// WaitForSingleObject(hthread,INFINITE);
// CloseHandle(hthread); CloseHandle(hread);
// ... meanwhile DWORD CALLBACK ThreadFunc(void *dat)
// { HANDLE hwrite = (HANDLE)dat;
// char buf[1000]={17};
// DWORD writ; WriteFile(hwrite,buf,1000,&writ,NULL);
// CloseHandle(hwrite);
// return 0;
// }
// // and now that the zip is created, let's do something with it:
// void *zbuf; unsigned long zlen; ZipGetMemory(hz,&zbuf,&zlen);
// HANDLE hfz = CreateFile("test2.zip",GENERIC_WRITE,CREATE_ALWAYS);
// DWORD writ; WriteFile(hfz,zbuf,zlen,&writ,NULL);
// CloseHandle(hfz);
// CloseZip(hz);
//
// (3) Handle use, for file handles and pipes
// HANDLE hzread,hzwrite; CreatePipe(&hzread,&hzwrite);
// HANDLE hthread = CreateThread(ZipReceiverThread,(void*)hread);
// HZIP hz = ZipCreate(hzwrite,ZIP_HANDLE);
// // ... add to it
// CloseZip(hz);
// CloseHandle(hzwrite);
// WaitForSingleObject(hthread,INFINITE);
// CloseHandle(hthread);
// ... meanwhile DWORD CALLBACK ThreadFunc(void *dat)
// { HANDLE hread = (HANDLE)dat;
// char buf[1000];
// while (true)
// { DWORD red; ReadFile(hread,buf,1000,&red,NULL);
// // ... and do something with this zip data we're receiving
// if (red==0) break;
// }
// CloseHandle(hread);
// return 0;
// }
//
所以,说到这里,尝试一些更像下面的东西:
#include "XZip.h"
int main()
{
TCHAR zipFilename[] = TEXT("C:\test.zip");
TCHAR directoryPath[] = TEXT("C:\Users\ttyler\Desktop\Software\Folder2\NewFolder\");
TCHAR entryName[] = TEXT("NewFolder");
HZIP hz = CreateZip(zipFilename, 0, ZIP_FILENAME);
if (hz == 0) {
// error...
}
ZRESULT res = ZipAdd(hz, entryName, directoryPath, 0, ZIP_FOLDER);
if (res != ZR_OK) {
// error...
}
CloseZip(hz);
}
