Re: Freeing the memory using delete operator for a class object created using new operator gives exception - C / C++ / MFC Discussion Boards

This might happen if you continue to use the pointer after using delete. After delete, set the pointer to 0, to make it easier to catch this.

Best wishes,

Any reason you are using char arrays instead of something like CString?

utf8-cpp

Because that is a right (warranted by the constitution) of the native developer?

God forbid I infringe upon anyone's rights Poke tongue | ;-P

However,

C++

char sSnpDesc[50];

sounds like some sort of description, and I've seen descriptions longer than 50 chars.

utf8-cpp

It looks just "A snapshot in the family album". I don't know if Daddy had more than 50 characters.

In World of Warcraft the maximum number of characters you can create over all servers is 50, so this definition looks perfectly valid to me! Poke tongue | ;-P

Ah! The trailing null!

If you specify the exception, it may provide more information for us to give you feedback.

Make sure of a few things:
-You're not using the pointer after delete
-You're not calling delete on something that has already been deallocated
-You're not calling delete on someone else's private member
-You're not deallocating across DLL boundries

Hi,

In my hook application ,while i am trying to connect throgh myconnect function i am getting the error Error: 183,Error: 10014..

I am redirecting the connect through proxy..

my connect call is

sockaddr_in *inName = (sockaddr_in *)(name);

inName->sin_family = AF_INET;

inName->sin_addr.s_addr = inet_addr("192.168.1.5");

inName->sin_port = htons(80);

int iResult = orig_connect(s, (struct sockaddr*)&inName, sizeof(inName));

Pls help me to solve this problem.

Please note you are passing the address of inName that is already a pointer to a sockaddr struct.
Change:

C++

int iResult = orig_connect(s, inName, sizeof(*inName));

Hi CPallini,
Thanks for your reeply..
I changed
int iResult = orig_connect(s, (struct sockaddr*)&inName, sizeof(inName));

to
int iResult = orig_connect(s, inName, sizeof(*inName));

But i am getting the error message
error C2664: int (SOCKET,const sockaddr *,int) : cannot convert parameter 2 from sockaddr_in to const sockaddr

try

C++

int iResult = orig_connect(s, (const sockaddr *) inName, sizeof(*inName));

i am still getting the same error 10014

Well, in order to get better help, can you please provide a link to the documentation of the orig_connect function? I cannot find anything about on the web.

Hi,

I want to get handle of an already opened window.

For this

I can not use FindWindow() API as Window's title is not known.

And also, I can not use Class name as it is not a registered class.

Can anybody tell me how to solve this issue?

Thanks in advance.

Regards
MSR

As far as I know, every window must belong to a registered class.

Hi, thanks for the reply.

But here we are not regidtering class explicitly. This is the code

CDlg* pDlg = new CDlg;

DialogBoxParam(hInt, MAKEINTRESOURCE(IDD_DLG),
                        hWnd, (DLGPROC)(*pDlg ).WindowMapProc, (LPARAM)pDlg);

I have tried using

FindWindow("CDlg", NULL);

But it is not working.

Now , how to go forward to find IDD_DLG.

Regards
MSR

Your windows is child of the hWnd one and as such must be searched for.

Use

EnumWindows
EnumChildWindows

and look for #32778 class name

use the SPY++ to test it

Mithrill $Shucks | :-\$

CDlg is the class which creates the dialog window and must use some Windows classname, either one of the predefined classes, or a new one registered before creation. What is the base of CDlg?

[edit]It is also likely that the dialog will contain a title that you can search for.[/edit]

Unrequited desire is character building. OriginalGriff

The DialogBoxParam function automatically assigns the predefined class name "#32770" (i.e. dialog box, see here[^]) to the newly created dialog.
