I'm trying to make an interactive batch file (.cmd) to run under Windows NT. The obvious way is to have a program that displays a prompt and sets an environment variable with the response, however
1) using _setenv (I'm in C/C++ here) only alters the environment for the current program, so the batch file that ran the program does not see them; conversely
2) altering the registry where the environment variables are kept (HKEY_CURRENT_USER\Environment etc.) has no effect until a new DOS shell is started, so the batch file that ran the program does not see them;
3) the old DOS method of getting the PSP and walking up the environment areas isn't allowed under NT (and there's never enough space in the environment area anyway);
If anyone knows how to write a program that can do this, or any other way of making a batch file intercative, I'd love to hear about it.
(PS I know that using VBS or some other scripting language is the right way to go, but I need this to run on any NT Server machine, and the CMD processor seems to be the only scripting engine that is guaranteed to be available)
Thanks
Dave

Dave - I dont know if you've since found a solution (or if Ive understood the problem), but here's my $AUD 0.02c worth (probably not worth much in other currencies)
I would start with :-
http://www.pgh.net/~newcomer/processes.htm
or
http://www.pgh.net/~newcomer/process.htm
or go to http://www.pgh.net/~newcomer/mvp_tips.htm and look for 'asynchronous process notification'
these solve the problem of starting (for example) a batch file and reading the console output back into a listbox etc ..
from there, the listbox could be parsed looking for certain triggers etc, to get the results.. 'Franky Braem' also has an article on Codeproject entitled 'Redirect' which could be used as a starting point.
If thats not what you want 100%, then how about creating a console window using one of the above techniques, and reading (much like screen scraping from it) directly - I have seen examples on doing this, but cant find any to hand right now ...

Thanks Garth, but either you've misunderstood the question or I've misunderstood the answer.
Basically all I want is a way of putting user interaction into a batch file, such that the user is prompted to enter values which can then be used by subsequent operations in the batch file (ie. passed to other programs as parameters, used in IF constructs, etc.).
There is(are) no Windows/windows involved here at all (except for the DOS box that the user runs the batch file in).
Thanks for trying anyway.

I have a Win 95 IBM with an AMD proc. All of a sudden the computer doesn't think the CD drive is connected anymore (it is I checked it). Is there any easy way to fix this (I have dried different drives) without replacing the mobo? I seem to think there was a software problem that caused that in 95 but can't remember for sure. Thans if you can help.

First, make sure the BIOS recognizes the drive during POST. If you see a logo instead of messages, you'll need to enter the BIOS setup to verify this. The exact way to do this differs from system to system. If you don't know, try hitting either F1, F2, DEL, CTL+ESC, CTL+BACKSPACE, etc. right after you hear the beep. If the BIOS doesn't recogize it then it's not a problem in Windows.
If the power led on the CD-ROM is constantly on, then chances are it's plugged in backwards. In this case, make sure you have pin 1 lined up correctly on the cable to the HDD (look for the pink strip) and from the mother board. If the power led doesn't come on at all, try a different power plug.
If none of that works, then plug everything in, and start Windows. Make sure you have the folder C:\WINDOWS\Options\Cabs (if it's an OEM install you should). There should be at least 70 something cab files in there. If there are, then go to the device manager and remove your CD-ROM drive(s) and channel controlers (IDE??) for the mother board. Restart Windows so it'll reinstall the drivers it's using.
If it still doesn't happen for ya, you're pretty screwed.

I'll try this.

I tried this but I think it is a hardware problem and the comp is like 8 or 9 years old so I don't want to lose it but don't want to spend alot of money

The bios recognizes it is connected and the driver thing doesn't work but I going to check some jumper settings.

is it possible to transmit only first 5 bits of a character through RS232.
The problem is:
For example the binary equivalent of 'U' is 0101 0101. I want to transmit only last five bits (i.e) 10101. I tried this by setting databits to 5 and stopbits to 1 or 2.but i am getting 0001 0101. i observed this on CRO.
can you please suggest the solution. ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

Hi Guys
I have following technical question. Maybe someone has the knowhow, so I wouldn´t have to worry about seeking further
I have a server, he receives as input parameter a port number. So I want to find out what process established the connection through this port.
More rigurous:
I would like to find a method about determining a Process ID knowing a port number of a connection opened by this process.
Any hint would be highly appreciated.
Thanx

One way to do this is to write a filter driver for the transport layer and maintain stats on sockets/processes. Sysinternals offers a utility that does this (href=http://www.sysinternals.com/ntw2k/freeware/tdimon.shtml), but no source.
But for the less rigorous case, can you encode the PID into PID + large_num (where large num = say, 10000) and bind to that port number before connecting? Then the server can call getpeername and deduce the PID.
Might require some massaging if one process opens more than one connection.
Why needest thou this?

Thanks a lot.
I will do it with your first approach. The whole thing is based on the need to make an app work in a Terminal Services environmnent. It's something strange, I got a telnet session on a foreign OS. From there I launch a command like RunWord. The process of this command retrieves through native API's the IP adress and client port number of the telnet session . These parameters are sent to a service on the Terminal Server, that now has to decide on what Session to open Word. So one approach is to search for the PID of the open port, to get from this PID the SessionID and to launch Word in this Session.
All I need is a roadmap and then I might be able to find a clue.

I need to come up with a way to manually start and stop an NT driver from within a program when the user does not have the administrative priviledge to do so.
It is necessary to restrict the user's access, (i.e admin priviledges), but it also necessary for the drivers our software uses to be in manual start mode, and start and stop from within the program.
Is this a possibilty? There must be some workaround...
Thanks.

How 'bout a service running with the proper privilege that does the work - the user app could communicate with it through a socket, perhaps, with requests to start and stop.

Can anyone tell me why my BIOS reports 512MB RAM and Windows Reports 511MB RAM?
This happens on my Win 98 machine at home, I'm running Windows 2000 at work but I haven't had a chance to confirm if it has the same behavior.
I hesitate to mention that I've looked on MSDN and not found anything because I know as soon as I do, someone will post a link to the appropriate information

Well, Windows XP Professional reports 512MB (BIOS) and 512MB (Windows). I wonder if this is a Windows 9x issue?

Well on my machine at work,
Windows2k is shows 522,544 KB (535085056 bytes)
512MB = 524288 KB = 536870912 bytes
536870912-535085056 = 1785856 (1744 KB)
a little math shows that 1744KB are missing, somewhere.
now i would expect the reverse (640K on the mother board).
So unless windows is finding bits that are defective and removing them
(the pages they are in?) from the memory pool, i can not explain it.

Its cause of the difference in taking 1 MB as 1024 KB and as 1000 KB. I think so anyway.

How do i create a logon script?
Any online tutorials or examples would be gratefully accepted!
.NET or not .NET? MFC is the question......

A logon script is basically a batch file, VBScript file ( i think u can use them or an executable. Just remember that Win9x clients can't run batch files with a .cmd extension.
The best way of doing it is ethier attach the script to each user individually using the Active Directory User Manager or using the group policy editor and move the users into the appropriate users into that group. Once done you can attach logon / logoff scripts to the whole group.
I seem to remember that the Win2k server help had a little information on doing it - thats how I worked it out anyways.

If all clients in a LAN are assigned an IP address from a DHCP server,how can I enumerate ip address of all clients connecting to the server?
I can not use broadcasting.
