am getting set of data output from a machine, as i should get the data output at a time, say for eg:1024 BYTES at a time in an array[1024], but am getting the data in chunks like
Lenght: 512
0x20 0x65 0x40..........512 bytes
Length:512
0x23 0x45 0xC 0xD......512 bytes
Length's are varying, not constant all the time.
how could i append the second set of data to the first set, say
array[513]=0x23, array[514]=0x45....array[1024].
dont say MEMCPY; if i use it, again the data is being stored as chunks only.

have you considered using STL containers, such as std::vector ?

ExitProcess and exit()

what is different ?

ExitProcess is part of the Win32 API - It's the low level function you call to exit a process. There is a more vicious version called TerminateProcess. exit is a CRT (C Runtime Library) function; every C/C++ compiler will have this function. On Windows it will be implemented in terms on ExitProcess but it will do some "house work" before hand. For example using the CRT function atexit you can register a function to be called when the process exits - If you use ExitProcess you will short-circuit the CRT code which calls them.

My advice would be that if you're not sure of the difference play it safe and use exit.

prefer using the defined consts:

When you create it make sure the WS_VISIBLE style is not set.

Use WM_CTLCOLOR (OnCtlColor) or WM_ERASEBKGND

Using OnCtlColor

HBRUSH CMyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{
   <font color=green>// Call the base class implementation first! Otherwise, it may
   // undo what we're trying to accomplish here.</font>
   HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

   <font color=blue>if</font> (CTLCOLOR_DLG == nCtlColor)<font color=green>// Is dialog</font>
   {      
      hbr = ::GetSysColorBrush(1);
   }

   <font color=blue>return</font> hbr;
}

if you want to change color of Buttons
I think first derived class Button

class CMyButton:public CButton
{
then use WM_DRAWITEM
};

void CMyButton::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
CDC* m_DC = CDC::FromHandle(lpDrawItemStruct->hDC);
...
...
...
}

place this code below in InitInstance()

SetDialogBkColor(RGB(219,226,242)//set back ground
,RGB(0,0,0));//set foreground

REceive events in serial comms

I need to write a small automation tool for product testing and we use RS232 for control.
Looking at the serial comms articles here they all seem to need you to scan for received characters rather than having an event and the VC6 sample which has an event uses the MSCOMM ActiveX control which can cause some portability problems for me.
Does anyone know of a method which will give events but doesn't rely on ActiveX?
Thanks.

AFAIK, all serial comms classes are event driven, due to the fact that they are using overlapped IO for the serial port communication. At least for reading the serial port.
Or am I totally wrong here?

Serial comms is done as a file operation usually, it is sockets that are event driven (AFAIK).
