7zip

I'm running some startup scripts (cmd/bat) on my small azure VM which include a file-transfer operation from a mounted VHD, and normally it finishes in about 3 minutes (copying files and extracting ~500Mb zip file with command-line 7z). When I scale out to ~150 instances, the same operation is very slow (up to 15 minutes in total, most of which is used by 7z). Also, the nodes which are the slowest to complete the bootup procedure are very hard to access at first using mstsc(animation is lagging and takes a lot of time to log in), but that might not be related. What could be the problem? We had

I've been pouring over the format description and source code for the 7z archive format, but I'm still having trouble writing a valid container. I assume I can create an empty container... anyway here's my start: std::ofstream ofs(archivename.c_str(), std::ios::binary|std::ios::trunc); Byte signature[6] = {'7', 'z', 0xBC, 0xAF, 0x27, 0x1C}; Byte major = 0; Byte minor = 3; ofs.write((const char*)signature, 6); ofs.write((const char*)major, 1); ofs.write((const char*)minor, 1); UInt64 offset = 0; UInt64 size = 0; UInt32 crc = 0; ofs.write((const char*)offset, 4); ofs.write((const char*)size, 8);

How can I write "hello" on the first field of the 7-zip "Add to Archive" dialog? I managed so far to trigger the 7-zip (windows 64x) "Add to Archive" dialog using this from pywinauto.application import Application app = Application().start(r"C:\Program Files\7-Zip\7zFM.exe") #set the app app.top_window_().Edit.type_keys(r"C:\Users\me\Desktop{ENTER}") app.top_window_().SysListView32.Select(r'test.txt') #select files in list app.top_window_().ToolbarAdd.TypeKeys("{ENTER}") #apply Then I can't select the Add to Archive dialog. 1: This did not work. I guess because it did not find the dialog. If

I am trying to use SevenZipSharp or/and Unrar library in C# WinForms .NET 3.5. I have this problem with multi rar archives that have diffrent naming for example: .rar, r01, r02, r03 and so on (this is easy) somefile01.rar, somefile02.rar, somefile03.rar .001, .002, 003 and so on. If i point Unrar or SevenZipSharp to wrong archive it will unpack that particular archive and leave rest unpacked. So i have to point the right one (unless i am doing something wrong). What would be the best way to check for that? For now i am checking if there are more then one .rar files inside directory then if so

I am trying to import zipped database files into Mysql using command prompt using the following command 7z < backup.sql.7z | mysql -u root test The root user don't have any password associated with it. test is my target blank database. I use 7zip for unzipping purpose. The zipped database i.e. backup.sql.7z is located in D drive. But it's giving the following error So, instead I used the following command 7z < backup.7z | mysql -u root test Note : This time I am using backup.7z instead of backup.sql.7z But then I get the following error Clearly there's something wrong with my SQL syntax.
