You can set the buddy for the spin control as
//m_spinCtrl is variable for the spin control and m_editctrl for edit box
m_spinCtrl .SetBuddy (m_editctrl.GetWindow(IDC_EDIT1));

Somethings seem HARD to do, until we know how to do them.

sir thanks for reply
but it does not work as i use this in oninitdialog function
m_spin.SetBuddy(m_edit.GetWindow(IDC_EDIT2));
whwre m_spin is variable of spin control
and m_edit is variable of edit control.

You need to override the function for OnDeltaposSpin1:

void CTestDlg::OnDeltaposSpin1(NMHDR *pNMHDR, LRESULT *pResult)
{
	LPNMUPDOWN pNMUpDown = reinterpret_cast<LPNMUPDOWN>(pNMHDR);
	CString s;s.Format ("%d",pNMUpDown->iPos );
	m_edit.SetWindowText (s);
	// TODO: Add your control notification handler code here
	*pResult = 0;
}

In message map add

ON_NOTIFY(UDN_DELTAPOS, IDC_SPIN1, OnDeltaposSpin1)
//add in the header file
afx_msg void OnDeltaposSpin1(NMHDR *pNMHDR, LRESULT *pResult);

and copy and paste the code for the implementation of the function as in my above post.
You can right click on the spin control if you are working with an MFC Dialog based application and then go to property window to implement this function.
Declaring functions/definitions are more error prone if they are done by hand and are not recommended.

Yes we can use this method to add a function but it is not recommended as with this method there are more chances of committing an error and then creating troubles.You can't remember the prototypes for all the handler's etc.

and if u r using the exact code in ur program then it won't work,

I have SetWinEventHook for my MFC application, but the WinEventProc is not getting called?

g_hWinEvent = SetWinEventHook(EVENT_MIN,
                  EVENT_MAX, 
                  NULL, 
                  (WINEVENTPROC)WinEventProc,
                  GetCurrentProcessId(),
                  GetWindowThreadProcessId(hWnd,0),
                  WINEVENT_SKIPOWNPROCESS);

Thanks in advance,
Abhishake Lahare.

If I want to limit the maximized size of a window (dialog based) while the user clicks the Maximize button, which WM_ message or CWnd member can I use? Thanks!

What is "Tracking size" ?

-- modified at 5:17 Friday 14th July, 2006
I figured it out. The size + cursor size (when outside the screen).

Handle WM_SIZE, the handler for WM_SIZE will have three parameters.
Use the first parameter 'nType' and handle accordingly

I always overrided the cx value with a constant despite what nType is. It's not working. And WM_SIZE is called when the dialog has been fully maximized.
