Repainting of dialog box takes time.

Le rner

Hi all, i m working on dialog box type aplication. i m using many controls,bitmaps over the button and background color for dialog box. after some time of using application, application takes time to repaint the dialog box. please tell me how can i recove it ,so dialog box display easily instead of time taken in repainting. thanks in advance.

BIJU Manjeri

it depends on the actions performed by each controls or the size of the bitmap etc. Please check that also. Your system spec also have considerable role.. :)

Le rner

When just start the application its working fine,but after some time its behaves like this. its occur on simple dialog box restore and Domodal of dialog box etc,here no button function is performed. please help me what can i do 4 this. thanks in advance.

Is it working fine in the initial startup? You mentioned above,"After some time use of application, application takes time to repaint the dialog box". thats why i am asking so...

R jeev K R

I think there is memory leak in your application. Check all the allocated memory status. After use release all allocated memory. Check it especially in bitmap loading code. Good Luck...

May be you can check for GDI leaks & memory leaks in your application. I think you can use Task Manager to verify it.

Detected memory leaks!

here i found Detected memory leaks!,but i dont know how can get the location of this memory leak, how can get at which porint or on wich function memory leaks. please help me for this. thanks.

R jeev K R

Can i see your code for loading the bitmap...?

Le rner

For buttons i use this.

CBitmapButton m_t_btn;
m_t_btn.LoadBitmaps(IDB_B_N, IDB_B_P, IDB_B_N, IDB_B_P);
m_t_now_btn.SizeToContent();

here IDB_B_N and IDB_B_P//id of image

and on dialog box i m using picture ctrl pf bitmap type and provide image id to used

R jeev K R

Is any memmory leak from CBitmapButton class..? Use this utility separately in a test app to check the behavior...

Le rner

actully i dont know how can i detected memory leak in application, so how can i know memory leak occur from CBitmapButton or not.

R jeev K R

Create a test application that using CBitmapButton class. Use the above code in that application and continuously use that application. Check the usage in Task Manager... It will help you to find the memory leak is from CBitmapButton ...

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...

Le rner

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 ?

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

Le rner

yes i add this in all *.cpp
