If it listens to ActiveX you could launch it first, then minimize it, then do your unzipping command. Do you know how to program in ActiveX?

hi i have a problem of decompressing a 7zip data in hide mode.

i tried system command as bellow

[statuse,~] = system(['"' 7zip software path '" -y x ' '"' path of file need to extract '"' ' -o' '"' path of destination folder '"'])

 it works but this will pops up the 7zip software application window on my screen. actually i don't want that too happen so i tried a another way

try 2:

i wrote a batch file looks like as below then i called that through matlab system function

cd "7zip software path" start/min 7zG -y x "path which contain my compressed file" -o"Output folder to store a extraction"

In this method am able to do extraction in minimized mode(not in hide mode) but before extraction finish matlab continuous its next statement to execute. actually i want to read one file which is present in the extraction but am not able to read that file because the matlab continuous it's execution before the extraction complete.

So at end i want to decompress some *.7z folder from matlab in a hide mode.can plz help on this....,

Hi all,

7zip file manager software given two exe versions as 7z.exe and 7zG.exe. 7zG.exe is the one for gui application and 7z.exe is the one for command line operation.so when you use 7z.exe the extraction will happen in hidden mode.

Yes, call the Matlab function system() combining the commands via && in following way:

1) to make an archive in a certain folder:

[status,cmdout] = system('C: && cd C:\Program Files\7-Zip && 7z.exe a -t7z -mx8 d:\test\archive.7z d:\test\archive.txt');

where: status - returned code of execution status; cmdout - returned message from the command line (useful to execution control & debug); C: - set C: as current disk; cd C:\Program Files\7-Zip - set the 7Zip installation folder as current; 7z.exe - call 7Zip with parameters: a - make the archive; -t7z - set type of the archive as 7Zip; -mx8 - set the compression level as Maximum; d:\test\archive.7z - file name of the future archive; d:\test\archive.txt - name of the file to be archived;

2) to extract an archive to a certain folder:

[status,cmdout] = system('C: && cd C:\Program Files\7-Zip && 7z.exe x d:\test\archive.7z -od:\test\');

where: status - returned code of execution status; cmdout - returned message from the command line (useful to execution control & debug); C: - set C: as current disk; cd C:\Program Files\7-Zip - set the 7Zip installation folder as current; 7z.exe - call 7Zip with parameters: x - extract the archive from the certain folder; d:\test\archive.7z - file name of the archive; -od:\test\ - extract to folder d:\test\ .

[status,cmdout] = system('"C:\Program Files\7-Zip\7z.exe" a -t7z -mx8 d:\test\archive.7z d:\test\archive.txt');

should eliminate the need to change default disk (which could lead to other problems)
