用C/C在Windows(XP/2003)上创建ZIP文件++

如注释中其他地方所述,这只适用于已创建的Zip文件。zip文件中也必须不存在该内容,否则将显示错误。下面是我能够根据接受的答案创建的工作示例代码。您需要链接到shell32.lib和kernel32.lib(用于CreateToolhelp32Snapshot)。

#include <windows.h>
#include <shldisp.h>
#include <tlhelp32.h>
#include <stdio.h>

int main(int argc, TCHAR* argv[])
{
    DWORD strlen = 0;
    char szFrom[] = "C:\\Temp",
         szTo[] = "C:\\Sample.zip";
    HRESULT hResult;
    IShellDispatch *pISD;
    Folder *pToFolder = NULL;
    VARIANT vDir, vFile, vOpt;
    BSTR strptr1, strptr2;

    CoInitialize(NULL);

    hResult = CoCreateInstance(CLSID_Shell, NULL, CLSCTX_INPROC_SERVER, IID_IShellDispatch, (void **)&pISD);

    if  (SUCCEEDED(hResult) && pISD != NULL)
    {
        strlen = MultiByteToWideChar(CP_ACP, 0, szTo, -1, 0, 0);
        strptr1 = SysAllocStringLen(0, strlen);
        MultiByteToWideChar(CP_ACP, 0, szTo, -1, strptr1, strlen);

        VariantInit(&vDir);
        vDir.vt = VT_BSTR;
        vDir.bstrVal = strptr1;
        hResult = pISD->NameSpace(vDir, &pToFolder);

        if  (SUCCEEDED(hResult))
        {
            strlen = MultiByteToWideChar(CP_ACP, 0, szFrom, -1, 0, 0);
            strptr2 = SysAllocStringLen(0, strlen);
            MultiByteToWideChar(CP_ACP, 0, szFrom, -1, strptr2, strlen);

            VariantInit(&vFile);
            vFile.vt = VT_BSTR;
            vFile.bstrVal = strptr2;

            VariantInit(&vOpt);
            vOpt.vt = VT_I4;
            vOpt.lVal = 4;          // Do not display a progress dialog box

            hResult = NULL;
            printf("Copying %s to %s ...\n", szFrom, szTo);
            hResult = pToFolder->CopyHere(vFile, vOpt); //NOTE: this appears to always return S_OK even on error
            /*
             * 1) Enumerate current threads in the process using Thread32First/Thread32Next
             * 2) Start the operation
             * 3) Enumerate the threads again
             * 4) Wait for any new threads using WaitForMultipleObjects
             *
             * Of course, if the operation creates any new threads that don't exit, then you have a problem. 
             */
            if (hResult == S_OK) {
                //NOTE: hard-coded for testing - be sure not to overflow the array if > 5 threads exist
                HANDLE hThrd[5]; 
                HANDLE h = CreateToolhelp32Snapshot(TH32CS_SNAPALL ,0);  //TH32CS_SNAPMODULE, 0);
                DWORD NUM_THREADS = 0;
                if (h != INVALID_HANDLE_VALUE) {
                    THREADENTRY32 te;
                    te.dwSize = sizeof(te);
                    if (Thread32First(h, &te)) {
                        do {
                            if (te.dwSize >= (FIELD_OFFSET(THREADENTRY32, th32OwnerProcessID) + sizeof(te.th32OwnerProcessID)) ) {
                                //only enumerate threads that are called by this process and not the main thread
                                if((te.th32OwnerProcessID == GetCurrentProcessId()) && (te.th32ThreadID != GetCurrentThreadId()) ){
                                    //printf("Process 0x%04x Thread 0x%04x\n", te.th32OwnerProcessID, te.th32ThreadID);
                                    hThrd[NUM_THREADS] = OpenThread(THREAD_ALL_ACCESS, FALSE, te.th32ThreadID);
                                    NUM_THREADS++;
                                }
                            }
                            te.dwSize = sizeof(te);
                        } while (Thread32Next(h, &te));
                    }
                    CloseHandle(h);

                    printf("waiting for all threads to exit...\n");
                    //Wait for all threads to exit
                    WaitForMultipleObjects(NUM_THREADS, hThrd , TRUE , INFINITE);

                    //Close All handles
                    for ( DWORD i = 0; i < NUM_THREADS ; i++ ){
                        CloseHandle( hThrd[i] );
                    }
                } //if invalid handle
            } //if CopyHere() hResult is S_OK

            SysFreeString(strptr2);
            pToFolder->Release();
        }

        SysFreeString(strptr1);
        pISD->Release();
    }

    CoUninitialize();

    printf ("Press ENTER to exit\n");
    getchar();
    return 0;

}

有鉴于此,我还尝试了另一张海报中提到的XZip库。这个库可以很好地用于创建Zip存档,但是请注意,使用Zip_FOLDER调用的ZipAdd()函数不是递归的,它只是在存档中创建一个文件夹。为了递归压缩归档文件,需要使用AddFolderContent()函数。例如,要创建C:\Sample.zip并将C:\Temp文件夹添加到其中,请使用以下命令:

HZIP newZip = CreateZip("C:\\Sample.zip", NULL, ZIP_FILENAME);
BOOL retval = AddFolderContent(newZip, "C:", "temp");

if (ZipAdd(hZip, RelativePathNewFileFound, RelativePathNewFileFound, 0, ZIP_FILENAME) != ZR_OK)

ZRESULT ret;
TCHAR real_path[MAX_PATH] = {0};
_tcscat(real_path, AbsolutePath);
_tcscat(real_path, RelativePathNewFileFound);
if (ZipAdd(hZip, RelativePathNewFileFound, real_path, 0, ZIP_FILENAME) != ZR_OK)

为此,我们使用XZip。它是免费的,它是C++源代码,工作很好。

-----原始答案-----

这里有这样做的示例代码

http://www.eggheadcafe.com/software/aspnet/31056644/using-shfileoperation-to.aspx

请确保您阅读了有关如何处理要完成的线程监视的内容。

编辑:从注释中可以看出,此代码仅适用于现有的zip文件,但是@ Simon

FILE* f = fopen("path", "wb");
fwrite("\x50\x4B\x05\x06\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", 22, 1, f);
fclose(f);

FILE* f = fopen("path", "wb"); 
fwrite("\x50\x4B\x05\x06\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00", 22, 1, f);
fclose(f);

这对我有用。然后我可以打开压缩文件夹。未使用第三方应用程序(如winzip)进行测试。

http://www.example-code.com/vcpp/vcUnzip.asp 其中有一个非常简短的示例,可以使用可下载库解压缩文件。还有很多其他可用的图书馆。另一个例子可以在名为 Zip and Unzip in the MFC way 它有一个完整的gui示例。如果你想用.NET来做,那么在System.Compression下总是有类的。

http://www.7-zip.org/sdk.html . 这包括几种语言的源代码和示例。

我不认为MFC或Windows标准C/C++API提供了内置zip功能的接口。

如果你不想发布另一个库,你可以一直静态链接到免费的zip库。。。
