May be the cleanup jobs are not done fully like bitmap's DeleteObject()

You should unload the bitmap. Refer the way youd load the bmp. D'Oh! | :doh:

Provided that you properly destroy the object, you don't have to worry about what Task Manager or similar tells you since it doesn't tell you what you think it does.

If you are dynamically allocating memory from the C++ heap, the heap will generally not be reduced in size when that memory is freed. One alternative would be to directly allocate your own memory from windows using GlobalAlloc.

Exactly where did you include them?

"_$h@nky_" wrote:

This seems self-explanatory. No definition for CEBLOB was found prior to line 2545 of pimstore.h.

Game console programming?

I want to learn C++ to be able to program on game consoles (mostly PS2, PS3 and Wii, not 360 or XBox), do you need to learn different commands and libraries than under windows?

I mean, obviously MFC and the everything about displaying windows won't work, but what about the rest?

And is there a way to test and debug a game on a windows PC without having to burn it to disc and test it on the console every time?

Thanks.

I suppose you've to use the proper development kit, for instance, PS3 possibly has it's own. But it's just a guess, since this morning I'm too lazy to google it for you.

It is important to understand the language. I see 2 parts:

1. "pure" C++ language, as mathematical operations and working with memory and the powerful (and that why dangerous) pointer arithmetics.

2. working with libraries or frameworks to target devices.

The first is for at most all the same BUT the second differences for the platform. So the libraries are depending for what target you develop. There are also libraries with more or less portability available. Compare the QT with the MFC. Or the IE with the FF => and the Addons for it.

Hi
In my Server and Client (CSocket) Vc++ MFC application , I want to send Server system time to Client and Set the Local time in Client

SetLocalTime( SYSTEMTIME );.is for setting the local time.

How can pass the SYSTEMTIME object through the socket.
So I send from server and receive in Client and assign it.

Thanks and Regards

I would pass it as any other chunk of data, i.e.

CSocket mySocket;
SYSTEMTIME st;
//...
mySocket.Send(&st, sizeof(st));

Thanks for u'r Reply

I tried u’r suggestion , sending is ok but how to receive it and type cast in to SYSTEMTIME

I Receiving as

char ch[1020];
CString m_str;
int m_Count = this->Receive(ch,strlen(ch));
ch[m_Count] = '\0';
m_str.Format("%s",ch);
AfxMessageBox(m_str);

Try this..

const int iSize = sizeof(SYSTEMTIME)
char szTemp[iSize];
SYSTEMTIME dtTime;

memcpy(szTemp,&dtTime,iSize);

You can also directly send the struct as indicated by CPallini..

in client side after you receive

SYSTEMTIME dtTime;

memcpy(&dtTime,szTemp,sizeof(SYSTEMTIME));

I hope it helps..

Yeah, you're not going to be able to do that - look at this page[^], specifically the second paragraph, where it says:

Services cannot directly interact with a user as of Windows Vista. Therefore, the techniques mentioned in the section titled Using an Interactive Service should not be used in new code
