Repainting of dialog box takes time.

[Le rner]

if i use application without CBitmapButton code,its still behave like this.

[R jeev K R]

That means, the problem is not from the CBitmapButton. Now check your dialog skinning code.Just like commenting the code for coloring the dialog or controls. This way you can find out the exact problem...

i use this for color

CBrush m_brush;
m_brush.CreateSolidBrush(RGB(241,244,250));//in OnInitDialog

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

switch (nCtlColor)
{
	case CTLCOLOR\_EDIT:
		pDC->SetTextColor(RGB(0,0,0));
		pDC->SetBkColor(RGB(255,255,255));
		return hbr;

	case CTLCOLOR\_STATIC:			
		LOGBRUSH logbrush;
		m\_brush.GetLogBrush( &logbrush );
		pDC->SetTextColor(RGB(0,0,0));
		pDC->SetBkColor(logbrush.lbColor);
		return m\_brush;
		

	case CTLCOLOR\_BTN:
	case CTLCOLOR\_MSGBOX:
	case CTLCOLOR\_DLG:
		return m\_brush;
	
	default:
		return m\_brush;
}

}

BOOL CTest::OnEraseBkgnd(CDC *pDC)
{
CPen myPen,hpenOld;
CRect rect;
GetClientRect(&rect);
for(int i=0;i<rect.bottom;)
{ myPen.CreatePen(PS_SOLID,1,RGB(241,244,250));
pDC->SelectObject(&myPen);
pDC->MoveTo(0,i);
pDC->LineTo(rect.right,i);
i++;
myPen.DeleteObject();
}
return 1
}

Could you post your BitmapButton.cpp here ? :)

Check your definition of Irrationality[^] :) 1 - Avicenna 5 - Hubbard 3 - Own definition

[Le rner]

CBitmapButton is a Visual studio class.

[R jeev K R]

I cant find any problem in your code... Any way just comment your code in the OnEraseBkgnd and try to sort out the problem... If the problem is still there then we can avoid this one also from the problem list...

[Eugen Podsypalnikov]

OK :) Do you have the following in all used *.cpp ?

#ifdef _DEBUG
#define new DEBUG_NEW
#endif

What output comes now after the exiting ?

1. Try to create, select and delete your background pen outside the drawing loop. 2) Could you post your *.cpp here ? :)

Actually you are filling dialog with RGB(241,244,250) color. Change the OnEraseBkgnd

BOOL CTest::OnEraseBkgnd(CDC *pDC)
{
CRect rect;
GetClientRect(&rect);
pDC->FillSolidRect(rect,RGB(241,244,250));
return TRUE;
}

to avoid for loop, unnecessary creation and destroying of pen,and filling dialog background color using LineTo and MoveTo functions. This one can make you drawing bit faster.
