Hi mate - Its a funny world. You have a problem for a few days so you post a question on a forum. Suddenly, you solve the problem - just like going to the doctor. You suffer anmd suffer, then you go their and u feel better just befopre appointment.

Sorry pal - i have removed the question. The solution was that a release operation on a bad pointer was omehow affecting the reference count of other objects.

Thx,

Why did you remove the question! It should have been there. It's very bad that people post question and when they get the answer they delete it. Someone else could have learned from your mistake. Imagine everybody here doing it.

Now even if you are specifying the solution here people won't know what you are talking about. No problem anyway. Smile | :)

My question is just regarding visual c++.Net.
I have an application that is working well in WindowXP Enviornment from last 3 year.This application is using VC++6.0 compiler for building application.
Now I have shifted this application building process from VC++6.0 compiler to VC++7.0.Net compiler.Now its working well in WindowXP environment.
But Its having some crashes while executing the application in Windows2K environment.
Can you exactly tell me how to trace out this problem.
Please reply as soon as possible.

Its crashes with error message "invalid memory access voilation" when executing the application in Windows2K environment.Crashes are not consistent.So it was not easily tracable.

Hi,
can any one tell how to read Windows NT Quota stream through Window NT Quota API. i have used these interfaces

IDiskQuotaControl
IDiskQuotaEvents
IDiskQuotaUser
IDiskQuotaUserBatch
IEnumDiskQuotaUsers

to get any specific information related to quota of user on NTFS. But i want to read Quota Data stream. (Like, to read standard data stream, alternate data stream etc on NTFS, we use BackupRead). Is there any Api through which we can read Quota data stream.

Thanks for ur reply.

Yah I had read this article. This only gives information of how to get any specific information for a quota assigned to a user on a NTFS volume.

I have found that in Windows NT, all the information about the Quota of NTFS volume is presented in $Quota system file.

While making backup of a file which exist on NTFS volume, i m able to read all the other streams like security stream, object id, standard etc through BackupRead api function which gives all the data related to a particular strema. That's what i want to do with quota stream also.

Plz guide me in this case.

Hello.

I need help. I wanted to close a port using a port number. Is this possible?

If yes, could anyone inform me how?

Thanks.

Alex

Inorder to close the Port, u need to close the handle of the Port,that u get from CreateFile.

hPort = CreateFile(..........);

for closing this,

if(hPort != NULL)<br />
  CloseHandle(hPort);

You cannot close the port by this method, if port is open by another application!
