To avoid flickering you have to handle WM_ERASEBKGND, and simply return TRUE

Hope this'll work.. Try it..

Try painting your controls in OnPaint() instead of OnDraw() and handle the erase back ground message

Hi, in my dialog i have one button "Item" by pressing this button second dialog will appear.
I need short cut key for opening this second dialog.
So i placed one accelerator for the ID of that second dialog (i.e)IDD_ITEM_DLG as ctrl I. And coded for this ID in mainframe class as Onitemdlg().But when i press ctrl I in my keyboard it does not works.
So, i made the same thing for that particular button in first dialog and coded in that first dialog class as the same .That time also it never works.
How can i do this?
P.S:when i write property for item button (i.e)&Item,
but in ouptput dialog nothing is display under I letter.

hi whitsky,

you have told to use invalidate, which will paint the entire window, but here once i have double click with the mouse i will genereate a Circle where i clicked and it must erase the first circle where i created.

sinario :
---------

first i created a Circle and double click any where in the screen
then at the double click a same circle what i have generated first it must created and the first created circle must disappear.

please help me out.

Add member member variables

protected:
	int m_nXPos;
	int m_nYPos;

Initialize them to some default values in ctor say 25 and 50

in OnPaint Function

dc.Ellipse(m_nXPos - 50,m_nYPos -25,m_nXPos + 50,m_nYPos +25);

make sure that this call after appears only after CDialog::OnPaint();

In double click handler do the following...

void CSampleDialogDlg::OnLButtonDblClk(UINT nFlags, CPoint point)
{
	// give default values
	m_nXPos = 50;
	m_nYPos = 25;

	if( point.x > 50) // check for minimum value
		m_nXPos = point.x;

	if( point.y > 25) // check for minimum value
		m_nYPos = point.y;

	InvalidateRect();

	CDialog::OnLButtonDblClk(nFlags, point);
}

Hope this works...
for avoiding flickering you may have to use double buffering technique.

Hi, friend.
I think using Invalidate() in the mouse double click event can solve the problem. I will check and convey you.
