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

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

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

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);

Thanks & Regards

SYSTEMTIME st;
Receive(&st,sizeof(st));

How to use GetForegroundWindow in service mode application in Vista operating system.

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..

Sandip.

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

It's all about the security, man....

Hi All

How can i insertitem in ClistBox through Threading?Plz help me

Cedric Moonen26-Mar-09 21:11

26-Mar-09 21:11

The simple answer is: you don't. You should never access UI elements from a different thread than the UI thread. If you have to do such a thing, rethink your design. A better option would be to "generate" your data in the thread and then send a user defined message to your window telling it to refresh itself. When receiving the message, your window will then fetch the data and add it to the list control.
I think this article[^] will help you a lot for threading.

			}	
	
	
	file.Close();	
}


return TRUE;
	

}

}

It's working but when i click on OKButton then it's show Assertion Failed Afxwil2.inl Line 731.

By the way, two remarks:
1) How does this code even compile ? How can you access your m_listba variable from your thread ? Is it a global variable Dead | X|

?

2) What's the purpose of doing that in a thread if you call WaitForSingleObject just afterwards anyway ? D'Oh! | :doh:

Help yourself and read the article I linked to you. Threading is not a simple subject that can be explained in 3 lines. If you want to use multithreading and understand what you are doing, then you'll need to spend a bit more time than asking a question on a forum.

MsmVc wrote
Yes m_listba is global variable.

That's really ugly, you should make it a member of your dialog class. You can't access it from your thread so why making it a global varialbe ?
And by the way, the "m_" suffix is usually applied to class member variables (m for member). If you use it on a global variable, it is totally confusing.

Cedric Moonen26-Mar-09 23:13

Then your code cannot compile (unless I missed something or you didn't post everything).

Anyway, we can discuss the whole day about minor details as this, it still won't make your code work because you can't access UI elements (like the list box) from a separate thread. Serioulsy, I have the impression to talk to a wall here Sigh | :sigh:

The worker thread shouldn't directly manipulate the GUI. It should instead post a message to the GUI thread, with in turns updates the GUI. It's not difficult, instead of calling InsertString from within the thread, call PostMessage with appropriate data. On receiving the message, the GUI thread will call InsertString.

The point is that everything is explained in the article, with an example and everything. And the example is about a list box being "populated" from a worker thread (through a message sent to the UI). So, I think this is a lost cause Sigh | :sigh:
