Like the other poster said, you could do a port scan, or run your client on the other end and that should send you a snapshot of the ports that the computer is listening on.

OP here.
There can be multiple instances of my app running on computer A, each listening on a different port. On computer B, I want to run a monitor app that can connect to any of the app instances running on computer A. It would be nice if I could enumerate those instances rather than having to just "know" what port(s) are listening.
What I might do is code my application to use a limited range or list of ports (say 100 fixed port numbers) and then code the monitor app to simply scan that list.

Perhaps you could select one specific standard port as a "management" port; computer B could open a connection to the standard port, and computer A would send back a list of its own open ports.

How to Write the Stored Procedure From Visual C++ with two arguments

Hello!
I have a Windows service which starts another application using CreateProcess. Thus, the application runs with SYSTEM privileges. This application calls LsaEnumerateLogonSessions, which returns the error code 8 (Not enough storage is available to process this command.). The service and the application are run under Windows 7 x64.
ULONG luLogonSessionCount = 0;
LUID *pLogonSessionList = NULL;
NTSTATUS lNtStatus = LsaEnumerateLogonSessions( &luLogonSessionCount, &pLogonSessionList );
LsaNtStatusToWinError( lNtStatus ) returns 8. Does anyone know the cause of this?
Thanks in advance!

Since you are using a timer, the WM_TIMER message will not be processed when you are in the for loop.
Try putting the following message loop within the for loop.
if (::PeekMessage(&msg, 0, 0, 0, PM_REMOVE))
::DispatchMessage(&msg);

So, you ask us to first download your program, install it and check what it is and then write the full source code for you ? Well, I think you'll have more success on www.rentacoder.com

While I see the small irony, I would not be overly optimistic.

So what's the problem? This is the default behavior. Only if you wanted a single instance to exist would you need to add any code.

replace all file (found) with an extension by the others,
name of that new file was not changed but its empty(does not have any infomation anymore).
please help me
sorry for everthing

What do you mean by replace?
Do you want to delete it or rename it?
You can do both using SHFileOperation[^].

I too don't understand for sure, but if you simply want to change the extension (rename the files) to a new extension, you can simply use the old DOS rename command.
rename *.xyz *.abc
Hope that helps.

No. example. file abc.xyz being replaced by new abc.xyz (the same name) (but this file is empty, no information inside)
|
|
|
|

So you want to keep the file but simply delete it's contents?
If so, open the file for writing and then close the file. As long as you don't specify "no truncate", this should delete all of the file contents.
Good luck.

I have a lib and its corresponding header file in C or C++ that I want to use it in Visual C++.net. The header file has a structure like this:
Reader.h:
class AFX_EXT_CLASS Reader
{
.
.
.
};
extern "C" AFX_EXT_API Reader * CreateReader();
There is no problem using the class but I can't use the CreateReader() function. There are 2 linkage errors: LNK2028, LNK2019.
Can you help me using this function please?
Thanks in advance
