You should really buy a book about VC++. It is nearly impossible to help someone who has almost no knowledge of VC++ or C++ through a forum. It will take ages to explain some basic concepts. You will be much more efficient by reading a book first.

i think that's the best thing to do for now?.. read a book and understand the concepts and terminology used in VC++. anyway, thanks for the advice.

and how do i get the current coordinates of the three buttons?

Using GetWindowRect()[^]

And then convert to client coords using ScreenToClient()[^]

Why not leave the buttons where they are and simply call ShowWindow(SW_HIDE) on each of the buttons?

Such as:

<br />
GetDlgItem(IDC_BUTTON1)->ShowWindow(SW_HIDE);<br />
GetDlgItem(IDC_BUTTON2)->ShowWindow(SW_HIDE);<br />
GetDlgItem(IDC_BUTTON3)->ShowWindow(SW_HIDE);<br />

Then somewhere else in your program if you want to show the buttons again:

<br />
GetDlgItem(IDC_BUTTON1)->ShowWindow(SW_SHOW);<br />
GetDlgItem(IDC_BUTTON2)->ShowWindow(SW_SHOW);<br />
GetDlgItem(IDC_BUTTON3)->ShowWindow(SW_SHOW);<br />

there is no need for hiding the controls., i got an idea that if the LEFT button is clicked, it scrolls all the way to the left until the three buttons are gone, then it shows up on the right side of the app window, likewise with the right button. then it should stop to where the three buttons are if the center button is prssed.

Like the <marquee> tag in HTML, it just scrolls to the direction, then shows up to the other side..

i think but am not sure if i need to get the coordinates?

need help guys. thanks..

Yes that will do the job.

Found an easy TODO for the Timer-Part here ("Using Timers in MFC Applications")

In our Sample it would look like this:

First update your class in MoveTheButtonDlg.h
(Some work is already done by VisualStudio when clicking the Button)

enum {DIR_STOP, DIR_LEFT, DIR_RIGHT};

// CMoveTheButtonDlg dialog
class CMoveTheButtonDlg : public CDialog
{

   ...

	DECLARE_MESSAGE_MAP()
public:
	afx_msg void OnBnClickedMoveright();
	afx_msg void OnBnClickedStop();
	afx_msg void OnBnClickedMoveleft();
	afx_msg void OnTimer(UINT TimerVal);  // TI: Add timer handler to messagemap

private:
	BOOL StartTimer (UINT TimerDuration);
	BOOL StopTimer(void);

    UINT_PTR m_nTimer;
    UINT  m_Direction;
    DWORD m_winpos;
};

After that you have to declare Message-Map:

BEGIN_MESSAGE_MAP(CMoveTheButtonDlg, CDialog)
	ON_WM_SYSCOMMAND()
	ON_WM_PAINT()
	ON_WM_QUERYDRAGICON()
	//}}AFX_MSG_MAP
	ON_BN_CLICKED(IDC_MoveRight, &CMoveTheButtonDlg::OnBnClickedMoveright)
	ON_BN_CLICKED(IDC_Stop, &CMoveTheButtonDlg::OnBnClickedStop)
	ON_BN_CLICKED(IDC_MoveLeft, &CMoveTheButtonDlg::OnBnClickedMoveleft)
	ON_WM_TIMER ( )  // TI: timer implementation
END_MESSAGE_MAP()

At last the new members have do be defined:

void CMoveTheButtonDlg::OnBnClickedStop()
{
	m_Direction = DIR_STOP; 
	StopTimer();
}

void CMoveTheButtonDlg::OnBnClickedMoveright()
{
	m_Direction = DIR_RIGHT;
	StartTimer(1000);
}

void CMoveTheButtonDlg::OnBnClickedMoveleft()
{
	m_Direction = DIR_LEFT;
	StartTimer(1000);
}

BOOL  CMoveTheButtonDlg::StartTimer (UINT TimerDuration)
{
   m_nTimer = SetTimer (IDT_TIMER_0, TimerDuration, NULL);

   if ( m_nTimer == 0) {
      MessageBox (_T("Unable to obtain timer"), _T("IDT_TIMER_0"), MB_OK|MB_SYSTEMMODAL);
      return FALSE;
   }

  return TRUE;
}// end StartTimer

BOOL CMoveTheButtonDlg::StopTimer(void)
{
	if(m_nTimer) {
       //  Stop the timer
       if (!KillTimer (m_nTimer)) {
         return FALSE;
       m_nTimer = 0;
       }
	}

    return TRUE;
} // end StopTimer


void  CMoveTheButtonDlg::OnTimer (UINT TimerVal)
{
	if(TimerVal != m_nTimer)  // TI: check what timer
		return;

	switch(m_Direction) {
	case DIR_LEFT:
		// TI: move to left here
		m_winpos-=5;
		break;
		
	case DIR_RIGHT:
		// TI: move to right here
		m_winpos+=5;
		break;
    }
}

I hope you can do the rest at "TI: move to ... " at your own

You already have the very good hint from Niklas Lindquist 14Jul'10.

SetWindowPos()[^] or MoveWindow()[^] to move the buttons

Every Button is based on a Window and SetWindowPos() can do everything
with the button (even hide it) if you are able to get the CWnd-handle.

See Example:

void CWinApp::HideApplication()

On the MSDN Online-Page (linked also by Niklas Lindquist) you really
should start to read MFC doku (See advice of Cedric Moonen).

You can get hints from the Forum, but nobody will do the complete work
for you.

What is the complete Funktion of your Application ?

-If you want networkfunktions you will probably get Timing an Sync Problems.

You can send every Button a message to get the same result as if you
pressed it, but over Network you will not see the monitor. You have to
find a way to send the results back to every client and display it.

Just leave your main() function empty. It can't get any faster than that.

You should use the faster approach. Big Grin | :-D

Seriously it may depend on a some factors like the complexity of your regex queries and the efficiency of your own search code (standard regex code is usually quite fast)

I guess Setcaption should accept a CString.
if that is the case, then you can format your float value to a string and then pass it to the SetCaption().

Hi!
I've two list boxes. These two list boxes contain similar elements at similar ids. i.e If List1 contains "Apple" as item0, List2 also contains "Apple" as item0. Similarly both the lists has 9 elements.My requirement is:
If I select "Apple" from List2, Apple could not be selected from List1. How to do this?
