Hi,

IMO the easiest way to do that is through a command line argument: just add a textual argument
to the ShellExecute() you already and let the called EXE watch and obey its command line.

UINT64 behavior VC6 C++

Hi,

the VC6 compiler gives me problems:

const UINT64 a = 0x0000000080000000;
results in just that, however

const UINT64 b = a << 1

results in 0x0000000000000000 !!!!

What am I doing wrong ?

Is there any way to force b into the required 0x0000000100000000

thanks,

Thank you for your answer.

Sorry, I should have mentioned that I try to do this in a header file.
In in function inside cpp file it works ok.

Also, as a global variable it does not work.
Maybe you could try that.

Thanks,

dynamic array use?

15-Jul-08 23:09

dear all

int *
nColumnCounts1
nColumnCounts2
nColumnCounts3
nColumnCounts4
nColumnCounts5

=new int[constant];
the following is dynamic arrays, and nColumnCounts1,nColumnCounts2,nColumnCounts3 were calculated already correctly, now i would like to calculate nColumnCounts4,nColumnCounts5 as per following formular. is this right way?

nColumnCounts4[m]=abs(nColumnCounts1[m]-nColumnCounts2[m]);
nColumnCounts5[m]=abs(nColumnCounts2[m]-nColumnCounts3[m]);

and then i can get new nColumnCounts4,5. however i couldn't correct result. anyone has suggestion to me, thanks a lot

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)?

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;
}
