Dear all,
Now I have a small program written by Borland C++ 3.1 for Win 16 bits, the function of this program is sent data from external PC Win 98 to another PC that run on Win 95. In fact this program run properly on Win 98, but when I run it on Win Xp thus it always be fault. Anybody please explain to me what is wrong and why it can not run on Win XP. If I want to run this program on Win Xp what I should do?

It's impossible to say whats wrong without knowing anything about the app or what the error messages are.

Please show me how to post file and imageto Message text? Thank you

You can't. You can't post a file, but you can post a link to the file uploaded somewhere else.
But, if anyone has a brain in their head, they won't download code they don't trust, and run it.
Like I asked before, got an error message?

I my VC++ program I call a small program written by Borland C++3.1 names: robot0.exe but this program functions to send data from PC to robot controller Win 95 operating system via COM port. However when it is called an error indicates in message box immediately.
16 Bits MS-DOS Subsytem
D:\WINDOWS\system32\cmd.exe
The system cannot open COM1 port requested by the application. Choose "Close" to terminate the application.
I kindly recieve any suggestion form you. many thank for your reply

It's possible your machine doesn't have a COM1. Look in Device Manager, under the Ports section. Make sure the Communications Port is labeled (COM1). Or the port is already open by another process, like a modem DialUp connection, or some other piece of software talking to the controller.
You can't have two processes using the same COM port at the same time.

You need to investigate into the Compatibility tab.

how to make read only usb drive to writable one
|
|
|
|
|
That would depend entirely on what made it "read only" in the first place.
One one of my thumb drives, there's a small, two position switch that makes it ReadOnly.

i am having usb which is paritioned as readonly. now i have to write files into it. how to do this?
|
|
|
|
|
Your going to have to use a piece of software, like Partition Magic, to change the ReadOnly attribute on that partition.

hi to all!!
when i shut down my laptop there comes End Now window ....
i am using xp home edition.please tell me why does it come like this...
why it does not shut down without this dialog box
thanks in advance....
|
|
|
|
|
It happens because there's at least one application or service that is not shutting down fast enough. The title of the application should be in the titlebar of that window.

Yes, it means that a process is not exiting (closing or whatever) fast enough when it receives the message to shutdown.
My Symantec AntiVirus 2006 has a couple of processes that do the same thing; they don't stop fast enough. I don't do anything; I give them more time to finish; they eventually do. If you give the process (whatever it is) time to finish and if it does then it is probably best to always do that. If the dialog box does not go away after a couple of minutes or fast enough for your requirements then you can push the End Now button and probably there will not be any damage to your data or whatever. It is best however to let the process finish if possible.

How common or uncommon is it that most employees have debug privileges for their Windows accounts?
I am a programmer and I know that many programmers use API functions that require debug privileges. I have tried to ask security programmers if it is common or uncommon for typical users to have debug privileges but they are not clear in their answers.
I am not a security specialist but as best as I understand Windows security it is possible to grant debug privileges to specific executables. Is management reluctant to do that or is it an acceptable compromise?

IIUC you only need the debug priv to debug processes started by another user. You can always debug processes that are running under your account. Giving a non-admin the debug priv is a security hole because that person could inject code into a system-level process and make it do something like run the Users control panel, and from there the person could add their account to the admins group.

Are you sure?
The ReadProcessMemory function states explicitly that the handle it uses must have PROCESS_VM_READ access. I don't know if PROCESS_VM_READ access is the same as Debug privileges or if PROCESS_VM_READ access requires Debug privileges but probably one of them is true since I have said in programming forums and such that the ReadProcessMemory function requires debug privileges and no one has said it is not true.
If it is true that any process that an account creates can use debugging functions on all other processes that the account creates then that is a security problem, since most users are not developers. If a non-developer executes a program that can access other processes then developers of the software would have access to data they should not have access to.

You have complete permissions (Full Control) to any process you create.
You can inspect a process's access control list using Process Explorer[^]. Go to the process Properties, Security tab and click Permissions. If you then go to the Advanced editor (click Advanced) and Edit, you'll see all the permissions detailed, including Read Memory.
You only need the Debug privilege to debug processes that you didn't create (and therefore don't have permission in the process's access control list).
