posted March 30, 2009 7:09 PM I'm using the ActiveX ZIP component. I am using the FileStore and trying to add a file, then save the file. It doesn't create any file though. If I use QuickZip, it works. But eventually I will need FileStore.Zip to work. Here is my code. IZip* ZipComp=0; CoInitialize(NULL); HRESULT hr=CoCreateInstance(CLSID_Zip, NULL, CLSCTX_INPROC_SERVER, IID_IZip, (LPVOID*)&ZipComp); if (!SUCCEEDED(hr)) { MessageDlg("Unable to create a ZIP object to use for opening/editing the zip file : "+EDITzipdownload->Text,mtError, TMsgDlgButtons() << mbOK, 0); return ; } try { ZipComp->FileStore->Add(EXEEdit->Text,false,true,"",zipNoEncryption); ISpanSettingsPtr span; ZipComp->FileStore->Zip("c:\\temp.zip", span); } catch (...) { ShowMessage("ERROR"); } ZipComp->Release(); CoUninitialize(); Thanks for any help.

posted March 31, 2009 3:41 PM I modified the DZip Sample that ships with the current version of the product by replacing the call to QuickZip in the HandleZip() function with the following code: Zipper->FileStore->Add("test.file",false,false,"",DartZip::zipNoEncryption); Zipper->FileStore->Zip(ZipFileName,false); The above worked fine for me. That being said, the sample uses a wrapper for IZip that we provide. ------ |
