I don't know, you didn't provide the class implementation code.

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

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?

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

However,

C++

char sSnpDesc[50];

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

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

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.

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

CPallini23-Aug-11 1:54

23-Aug-11 1:54

try

C++

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

vkgktm23-Aug-11 2:04

i am still getting the same error 10014

CPallini23-Aug-11 2:09

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.

CPallini23-Aug-11 2:25

"But all I can do is hand it to you": Google search for "proxy request denied"[^].

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
