Hint 1: Post the actual code.
Hint 2: Use the code block button to surround code snippets with <pre> tags.

thanks for your reminder. this is actual code. i would like to get nColumnCounts4,nColumnCounts5. is this code right? however i just can get same big value. couldn't get what i want. where is problem, thanks.
nColumnCounts1,nColumnCounts2,and nColumnCounts3 are all right, i checked already.

int a = _iBoundheight%3; // remainder 
	
	for(iY=0;iY<(a+(static_cast<int>(_iBoundheight/3)));iY++)
	{
		for (iX=_iBoundx;iX<_iBoundwidth;iX++)
		{
			if (ImgArray[iX+iY*_iBoundwidth] == 255)          
			{			
				nColumnCounts1[iX]++;  

			}
		}
	}
	
	for(iY=(a+(static_cast<int>(_iBoundheight/3)));iY<(a+2*(static_cast<int>(_iBoundheight/3)));iY++)
	{
		for(iX=_iBoundx; iX<_iBoundwidth; iX++)
		{
			if (ImgArray[iX+iY*_iBoundwidth] == 255)          
			{			
				nColumnCounts2[iX]++;  

			}
		}		
	}
	
	for(iY=(a+2*(static_cast<int>(_iBoundheight/3)));iY<_iBoundheight;iY++)
	{
		for(iX=_iBoundx; iX<_iBoundwidth; iX++)
		{
			if (ImgArray[iX+iY*_iBoundwidth] == 255)          
			{	
				nColumnCounts3[iX]++;  

			}
		}		
	}
	

	// Average
	int a1,a2,a4,a5,s1,s2,s3,r1,r2,r3,av1,av2;
	a4=a5=0;
	s1=s2=0;
	r1=r2=0;
	av1=av2=0;
		
	// Standard deviation
	for (int m=0;m<_iBoundwidth;m++)
	{
		nColumnCounts4[m]=abs(nColumnCounts1[m]-nColumnCounts2[m]);
                nColumnCounts5[m]=abs(nColumnCounts2[m]-nColumnCounts3[m]);
		a4=a4+nColumnCounts4[m];
		a5=a5+nColumnCounts5[m];
	}
		
	av1=a4/_iBoundwidth;
	av2=a5/_iBoundwidth;
	
	for (int m2=0;m2<_iBoundwidth;m2++)
	{
		s1=s1+pow(nColumnCounts4[m2]-av1,2.0);
                s2=s2+pow(nColumnCounts5[m2]-av2,2.0);
	}
	
	_fFeature[0] = sqrt(s1/_iBoundwidth);
	_fFeature[1] = sqrt(s2/_iBoundwidth);
	
		
	delete[] ImgArray;
	delete[] nColumnCounts1;
	delete[] nColumnCounts2;
	delete[] nColumnCounts3;
	delete[] nColumnCounts;
	delete[] nColumnCounts4;
	delete[] nColumnCounts5;
	
	return true;
}

av1, av2 should be declared double (or float).
Then change the above expression to:

av1 = (double)a4 / _iBoundwidth;
av2 = (double)a5 / _iBoundwidth;

gentleguy wrote:
s1=s1+pow(nColumnCounts4[m2]-av1,2.0);
s2=s2+pow(nColumnCounts5[m2]-av2,2.0);

Again, s1, s2 should be declared double.
Those declarations will fix the (otherwise wrong) above expression .

BTW: Are you aware that all that static_casts you're using are useless (and contributes to overall code entropy)?

however i couldn't get nColumnCOunts4,5 arrays value. what is problem. i corrected as per your remind.thanks a lot.

Button Notification

15-Jul-08 22:47

Dear All,

I want to use the BCN_HOTITEMCHANGE event for a button. I included the event using the properties of class for a button, but the event is not triggered when the mouse enter or leave from the button. Please help me. The code snippet is as follows :

void TestDlg::OnBnHotItemChangeButton4(NMHDR *pNMHDR, LRESULT *pResult)
{
	// This feature requires Internet Explorer 6 or greater.
	// The symbol _WIN32_IE must be >= 0x0600.
	LPNMBCHOTITEM pHotItem = reinterpret_cast<LPNMBCHOTITEM>(pNMHDR);
	m_button4.GetClientRect(&rect);
	if(pHotItem->dwFlags==HICF_ENTERING)
	{
		MessageBox("Mouse entered");
	}
        else if(pHotItem-&gt;dwFlags==HICF_LEAVING)
        {
		MessageBox("Mouse leaved");
        }
        else{}

		*pResult = 0;
}

Yes I included the line

"version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")

and I am using VS2005 so that I dont change the manifest file. Eventhough the event is not working. Please advice.
P.S. Please tell me whether to add the ComCtl32.lib or not.

I think the checking should be modified as follows

if(HICF_ENTERING == (pHotItem->dwFlags&HICF_ENTERING))
{
	MessageBox("Mouse entered");	
}
else if(HICF_LEAVING == (pHotItem->dwFlags&HICF_LEAVING))
{
	MessageBox("Mouse leaved");	
}

Dear Naveen,

The event handler does not respond to the mouse over and mouse leave event. (I set a breakpoint in the event handler to check this). I think there must be some more things to do. Please advice.

Please check the below things..

1. _UNICODE is defined in your project settings( project should be unicode )
2. The window have the XP look and feel while running.
3. The entry in the message map is correct.

Hello Naveen,

Now it is working. Thank you so much for your guidance. The problem is that the UNICODE is not set.

Now another issue, when I set the button as OWNERDRAW the event is not triggered. I want to change the bitmap for the button on both the mouse over and mouse leave events. Please advice.
