460.0. "CreateProcess returns 'No such file or directory' for a 'ver'" by CRONIC::LEMONS (And we thank you for your support.) Mon Feb 10 1997 09:55

    Visual C++ for Digital Alpha V4.2
    
    Hi
    
    We're using:
    
    	//Get the windows directory path for use in CreateProcess
    	GetWindowsDirectory(WinDir, MAX_PATH);
    
    	// Create a process and execute the command. 
    	// CreateProcess returns FALSE on error (of creating the process,
    not the command)
    	tfStatus = CreateProcess(NULL,lpszCommand, NULL, NULL, TRUE,
    NORMAL_PRIORITY_CLASS,
    		NULL, WinDir, &StartupInfo, &pInfo);
    
    When we feed this command a value of 'Ver' for lpszCommand, we get a
    value of 2 in GetLastError, which strerror translates to 'No such file
    or directory'.  Oddly enough, if we pass a value of 'net start
    {servicename}', the Create Process functions normally.
    
    WinDir has a value of D:\WINNT, which is a valid directory on this
    system.
    
    Any thoughts?
    
    Thanks!

	When we feed this command a value of 'Ver' for lpszCommand, we get a value of 2 in GetLastError, which strerror translates to 'No such file or directory'. Oddly enough, if we pass a value of 'net start {servicename}', the Create Process functions normally. There is no such image "ver" on the system. It is an internal command to the command shell. Try "command /c ver" or "cmd /c ver". That might work. (Note there is NO copy.exe either !!!)

	If you're looking for the Windows Version number, there are other easier ways to do it. If this is just for a test, run a real executable. Danny

	I'm trying to write a DLL, centered around CreateProcess, that will handle any command thrown at it, internal command or external program. Any suggestion on how to do this? Thanks! tl

I think the "easy" way to do this is detect if running on Windows NT or Windows 95 and then either put a "cmd /c " or a "command /c " in front of the command. If you don't do that then I think you have to handle .bat/.cmd files, DOS images, WIN16 images, internal commands and lots of other stuff.
