You need to see how MFC function CWnd::CenterWindow is impplemeted. Step through that function while debugging and see how it is implemented.

I have a small program that is written on Borland C++ 3.1, it worked probarly on Win98 but now I need to reuse this program on WinXP, howerver there is an error when i use it on WinXp. Any body know to convert this program into Win32 application. What is bios.h header file. Could I rewrite a new application and then aopy these code again?

The problem is that functions defined in the ‘bios.h’ (equivalent to MS ‘dos.h’) header file are used to access low level bios functionality (indirect assembly code). In other words, it is designed to talk to the computer at the bios (or machine) level. These functions usually need to be replaced with equivalent Win32 functions that you may need to write yourself. I know that there is a [free] driver on the Net that allows you to access this level (ring 0), because I have used it, but I do not remember what it is called.

Well yes and no, in either case you will need to recompile the code and look at the errors (or warnings) and figure out how to do the equivalent in Win32

How can I find the Sharedmem file mapping object name?

Hello,

I am trying to extract data from an application with a sharedmem, however the function call to OpenFileMapping requires that I have the name of the file mapping object which I don’t have.

Is there some way that I can find the name of the available file mapping object for this application?

No, there isn't. The other application may have created multiple file-mapping objects, each with or without a name. If it's a named file-mapping object, that name has to be unique within the application. I *think* you can create multiple unnamed file-mapping objects.

Best,
Jun

Handling of ESCAPE and RETURN

I want to handle the ESCAPE key in certain situation; I try to catch it in PreTranslateMessage with WM_KEYUP.

Pressing ESCAPE leads always to the "cancel" result.

If I have a control named IDCANCEL, the OnClicked handler receives the control, whenever
ESACPE has been pressed, but I can not differentiate between clicking on that control
and the "true ESCAPE".

Is there a way I can separate the "escape" key from the CANCEL button and from "exit" ("X" in the system menu)?

Actually, I need it in a CEdit control.

Refer this[^].
Similarly, use VK_RETURN for enter key.

Give the button a different ID and a new handler for this ID, than it should work.

To catch up ESCAPE you need to catch the WM_KEYDOWN Event.
But it is important where the PreTranslateMessage.
Try to catch the WM_KEYDOWN event in your Dialog class.

See

HBRUSH CDialogDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

pDC->SetTextColor(RGB(20,120,220));//text
pDC->SetBkColor(RGB(20,120,220));//background
	return hbr;
}

You must insert WM_CTLCOLORmessage to your program and for radio button its working Wink | ;)

and again a short help

BEGIN_MESSAGE_MAP(CDialogDlg, CDialog)
ON_WM_CTLCOLOR()
END_MESSAGE_MAP()

HBRUSH CDialogDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

pDC->SetBkColor(RGB(20,120,220));
pDC->SetTextColor(RGB(255,255,220));

	return hbr;
}

/////////////header file/////////////
public:
afx_msg HBRUSH OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor);
