Pleasure.

Be mindful of the fact that this will keep track of the position and velocity of the head of the snake only. In order to keep track of the body segments, you'll need to maintain an array (or list) of the coordinates of each of the body segments.

I'd suggest you deal with that bit later, after you have position and movement nutted out.

Why GlobalAddAtom always returns none zero even if failed

how do you know it failed, if the return code is non-zero?

Return Value
ATOM
If the function succeeds, the return value is the newly created atom.
If the function fails, the return value is zero. To get extended error information, call GetLastError.

Re: Sorry I can't type in the 'Text' field. I use the GlobalGetAtomName to retrieve the atom name, and it doesnot match the origin name. This occurs when I Add more than 0x4000 atoms.

yes. there is a limit of 0x4000 string atoms per process:

http://msdn.microsoft.com/en-us/library/ms649053%28v=vs.85%29.aspx[^]

The values of string atoms are in the range 0xC000 (MAXINTATOM) through 0xFFFF.

Hello Guys,

Anyone knows how to create an Out-process ActiveX Control ?

I'm trying to use 'CreateControlLicEx' function to create the control from my WIN32 application but it only works for In-process ActiveX. Cry | :((

thanks

Freeing the memory using delete operator for a class object created using new operator gives exception

Freeing the memory using delete operator for a class object created using new operator gives exception.

The class is
class CSnp : public CObject
{
public:
CSnp();
~CSnp();
char liststr[50];
char sSnpDesc[50];
CTime tDateTime;
int iDCSSerialKey;
};

Is there anything wrong in the class?

class looks fine. make sure you haven't written past the ends of either of those arrays, though.

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

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?

However,

C++

char sSnpDesc[50];

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

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.
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
