[Req] Switch to hide 7zG progression window

[Camarade_Tux]

Hi,

I have a project (not yet public) and I use 7zip to extract many many .7z files.

The problem is for each file extracted, I get a window that appears and usually disappears within 2 seconds.
7z's progress bar is usefull but with my small archives, it's 0% then 100%.

I'd like to have a switch (-hide) to hide 7zG.exe, i.e. not to have it show its window.
I'd done it myself if I could compile 7zG.

Even better would be a "-hideXXX" switch where XXX is a threshold. If size is more than XXX, then progressbar is displayed (I have a *big* list of files and it would be far easier to use "Search and Replace" :P )

I know -hideXXX will probably not be added, but -hide should be pretty easy. :)

Thanks a lot. ^^

You can call command line version (7z.exe) with disabled window (win2000 and WinXP allow it).

How can I have this disabled window ?
There is no compatibility problem since my project runs on XP (maybe on 2k) but not on Win9x but I never heard of that disabled window.

PS: is there no way to "track" a discussion on SF's boards ?

No way now. Probably I'll add switch in future.

For 7za.exe or 7z.exe, I recently found an app called HStart.
Let's quote from the official website ( http://www.ntwind.com/software/utilities.html ):
"Starts console applications without any windows "
And it is working at 100% !

I had a problem with spaces in paths.
I asked for help and the author told me I had to escape the quotes used for 7za.

That's what I had:
%WIHU%\hstart "7za.exe x "%WIHU%\Apps\Navigateurs\K-Meleon.7z" -o"%KMeleon%""

And that's what it had to be:
%WIHU%\hstart "7za.exe x \"%WIHU%\Apps\Navigateurs\K-Meleon.7z\" -o\"%KMeleon%\""

(the space was in %KMeleon%)

That's it. :)

you can use that code to start process with no window (only for console applications and only under windows 2000 and higher), thanks to MSDN:

#include <windows.h>
#include <stdio.h>
#include <tchar.h>

void _tmain( VOID )
{
    STARTUPINFO si;
    PROCESS_INFORMATION pi;
    LPTSTR szCmdline=_tcsdup(TEXT("MyChildProcess"));

    ZeroMemory( &si, sizeof(si) );
    si.cb = sizeof(si);
    ZeroMemory( &pi, sizeof(pi) );

    // Start the child process.
    if( !CreateProcess( NULL,   // No module name (use command line)
        szCmdline,      // Command line
        NULL,           // Process handle not inheritable
        NULL,           // Thread handle not inheritable
        FALSE,          // Set handle inheritance to FALSE
        CREATE_NO_WINDOW,              // The process is a console application that is being run without a console window
        NULL,           // Use parent's environment block
        NULL,           // Use parent's starting directory
        &si,            // Pointer to STARTUPINFO structure
        &pi )           // Pointer to PROCESS_INFORMATION structure
    )
    {
        printf( "CreateProcess failed (%d).\n", GetLastError() );
        return;
    }

    // Wait until child process exits.
    WaitForSingleObject( pi.hProcess, INFINITE );

    // Close process and thread handles.
    CloseHandle( pi.hProcess );
    CloseHandle( pi.hThread );
}

Is there anywhere a compilied Version available from  this?

Or can someone compile the Code ahead and release it?

Thanks forward.
