Hidden Windows Explorer

[shinichi81]

1. I create a background Windows Explorer (by using CreateProcess() function with szCmdline = "explorer.exe /select,C:\" and hidden option).

After that, from Desktop, right click "My Computer" then select "Open". If I close this Windows Explorer, my hidden windows is disappeared.??? (they all have the same class name, "CabinetWClass"). Do you have any idea about this?

2. Is it safe if I do as below:

- Check all windows to find Windows Explorer (by using EnumWindows).
- If not found -> create hidden windows explorer again:

if( !CreateProcess( NULL,   // No module name (use command line)
        szCmdline, 
        NULL,       
        NULL,      
        FALSE,      
        0,           
        NULL,         
        NULL,         
        &si,           
        &pi )         
    ) 
    {
        printf( "CreateProcess failed (%d).\n", GetLastError() );
        return;
    }
    // Do not use WaitForSingleObject( pi.hProcess, INFINITE ) here is ok?
    CloseHandle( pi.hProcess );
    CloseHandle( pi.hThread );

3. I alse do not terminate process (or thread) of hidden windows explorer (left until shutdown). Is this ok?

Many thanks for your help.
