Hello Sir
Thankx for taking time for my problem.
I have already written what is the line number 310 by comment...Still I am writing this again here....For whole code you can just look it back to my problem on Codeproject at http://www.codeproject.com/script/comments/forums.asp?msg=960928&forumid=1647#xx960928xx
Line number 310 and onwards....
------------------------------
sOut = new char[len + 1 + 25]; // Here sOut is not been freed after allocating memory
sOut[0] = '<';
sOut[1] = 'A';
sOut[2] = 'E';
sOut[3] = 'S';
sOut[4] = '_';
sOut[5] = 'E';
sOut[6] = 'n';
sOut[7] = 'c';
sOut[8] = 'o';
sOut[9] = 'd';
sOut[10] = 'e';
sOut[11] = '>';
.

As your procedure returns the sOut char * pointer, its now the responsibility of the callee to delete the memory. TYpically what you are doing here is bad practice as you have to remember to delete it. If you returned an std::vector<char> then if it was not used its desturctore would be called and it would delete itself thus avoiding the leak problem.
std::vector<char> sOut;
sOut.resize(len + 1 + 25);
...
return sOut;
If you vote me down, my score will only get lower

Hi
I have developed one simple DLL in VC++ as Project->New->Win32 Dynamic Link Library->An empty DLL project......
Now there is some Memory Leak in my DLL. But I don't know how to trace it and which functions or line is making memory leak.
All the programm to find Memory Leak I found is for EXE only....
So someone suggested me to go for IBM's Rational Purify Evaluation for windows. I use Windows 2000 Professional as OS. I downloaded it but it is asking for Licence Key ...and I am not able to go ahead from here....any suggestion please....Or any other software such as this...?
Pls help me out
Regards
Mahesh

Hi,
Usually what they'll do is they'll send a licence key 2 your email id after download itself. So check @ their site itself or drop a mail to their support division.They will surely help you.

Erkenntnisse zur DLL-Programmierung
Wenn man eine exportierte Klasse verwendet kann man diese nicht mithilfe von LoadLibrary und GetProcAdress nutzen. Klassen muss man über Load Time Linking verwenden, nicht über Run Time Linking. Eine Mischung aus Load Time Linking und Run Time Linking kann aber dennoch verwendet werden. Funktionen (in der DLL), die nicht Memberfunktionen von Klassen sind, lassen sich gleichzeitig über Run Time Linking ansprechen. Doch das ist dann ja sowioeso überflüssig, da alle Vorteile des Run Time Linking dahin sind.
Wenn die Funktion LoadLibrary Namen die vorhanden sind nicht findet, könnte das daran liegen, dass die Namen beim Compilieren und Linken verändert werden. Da wird zum Beispiel aus fnMyTREE dann ?fnMyTREE@@3HA. Zwei mögliche Lösungen: 1. Kann man per .DEF-Datei die korrekten (ursprünglichen) Namen vorschreiben, hier können sogar Aliase vergeben werden! 2. Kann man den veränderten Namen einfach in der GetProcAdress-Funktion verwenden: GetProcAddress(hinst,"?fnMyTREE@@3HA"); Das klappt!
Ich suche noch folgende Info´s:
Weiss irgendjemand von einem Script, das beschreibt, wie man DLL´s prinzipiell verwendet. Also Fragen zur Programmiertechnik wie z.B.:
Sollte ich eine DLL-interne Klasse in der Entry-Funktion allokieren?
Sollte man eine Kontroll-Klasse gänzlich der Aussenwelt verbergen?
Wer kennt sinnvolle Konstrukte oder mag mir mal seine Programmiermethoden offenbaren.
Wo findet man Codebeispiele zu diesem Thema?

Hi all,
Is there any way to check whether a stored procedure is present in the Database or not. Iam using SQL Server as the db and using ADO 4 programming using MS VC++ 6.0
Thanx in advance
Sujan
Note: I KNOW THAT WE CAN CHECK IT USING TRY-CATCH,IS THERE ANY OTHER WAY OTHER THAN THIS
|
|
|
|

use the same query that the SQL generator to see if the stored procedure is there. It is a query of dbo.master.sysobjects.

I'm going to patent thought. I have yet to see any prior art.

Hi,
From where. If it is from Inet, you have use the CInternet session and its related classes, if it is from Outlook express then you have to use Outlook automation.

hi,
I need to check mail from Internet. How could i use CInternet session, is there any sample.
I need to create an MFC application to show all the mails from internet. I can provide pop address, userid and password. My application should download all the messages in that with full details (subject, from whom it comes, attached file etc...)
simply, I need to create MFC application similar to that of outlook but in my own format....
Thanks
Be simple and Be sample.

But for now have a look @ the following link

Hi!
I want to develop an applcation in VC6, which detect and then plot the graph of network traffic. This graph should be avaialble to user on a web browser.
I don't know where to start except somewhere I should be using winsock.
I am Intermediate level in Win32SDK and beginner for MFC.I hate java and want to prove that better things can be accomplished using VC than that Lazy Java.
Three Cheers for this forum and VC community

yeah Buddy i am too the Vc Fan.
About your problem,you have to use iphelper api not
winsock.
there is good example of firewall by Sudhir Mangla
to get the network traffic.
about ploting the graph,from what ever i know,you
can follow this little logic or wait for other
Programmer to reply.
->if you familiar with any WebLanguage,just write
the data into the file and notify that webpage
about the data you have recieved from network to
disply it on WebBrowser

you can do this by reading the data file written by you network application at regular interval. easiest way i think.

I am working with crystal reports 10 in vc++ 6.0 and need to create a new report. I am using the following piece of code.
#import "craxdrt.dll" no_namespace<br />
<br />
IApplicationPtr m_pApplication;<br />
IReportPtr m_pReport;
....
m_pApplication.CreateInstance("CrystalRuntime.Application");
....
Everyting goes fine till here. But as soon as i call the NewReport() method in the IApplicationPtr it throws a com exception.
m_pReport = m_pApplication->NewReport() throws a com exception.
Dont know whats going wrong.
