   Please correct your post to fix the typos you mention in later posts.

   Does the CLineInfo overload its operator new for custom heap/caching/allocation purposes? If so, that will likely raise the error because the heap management will be different.

   If you are allocating in one file and deleting in another, make sure that all files involved have the #define new DEBUG_NEW (VC++ 6.0) at the top of the file, or you could end up using different heap routines.

   Peace!

No! no overloading of new/delete.

But I must have had som other error that is fixed now, that overwrote the memory or something. because delete[] work now.

But _CrtIsValidPointer still does not work when checking a pointer of an array of objects with a destructors. Because of a bug in CrtIsValidHeapPointer.
but as a workaround I can use

_CrtIsValidHeapPointer( ((LPCBYTE)p)-4 );

Where do you want to select the numbers from?
If you want to generate random number's use rand()

Somethings seem HARD to do, until we know how to do them.

use the modulas(%) operator with rand() to get the numbers in the range like

i is between 0 to 4.

u should return a brush of required color to do that

CBrush bkBrush( RGB(0,0,0));<br />
<br />
<br />
HBRUSH CAfterone::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) <br />
{<br />
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
<br />
// TODO: Change any attributes of the DC here<br />
pDC->SetBkColor(RGB(0, 0, 0));<br />
<br />
// TODO: Return a different brush if the default is not desired<br />

Here's the code snippet : To change only the background color

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

	// TODO:  Change any attributes of the DC here
	HBRUSH hBr=CreateSolidBrush (RGB(255,0,0));
       
        if(pWnd->GetDlgCtrlID ()== IDC_EDIT1)
	{
	    pDC->SetBkColor (RGB(255,0,0));
	    hbr=hBr;
	}
	// TODO:  Return a different brush if the default is not desired
	return hbr;
}

Is it OK!

The following code changes the color of the all the EDIT controls of the dialog CtestMFCDlg.

HBRUSH CtestMFCDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)<br />
{<br />
	HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
        if(nCtlColor== CTLCOLOR_EDIT )<br />
		hbr=CreateSolidBrush(RGB(0,100,0));<br />
	return hbr;<br />
}

I think following code will solve ur problem

if(pWnd->GetDlgCtrlID()==IDC_EDIT1)<br />
{<br />
    CRect rect;<br />
    pWnd->GetClientRect(&rect);<br />
    pDC->FillSolidRect(&rect,RGB(255,0,0));<br />
    pWnd->ReleaseDC(pDC); <br />
}<br />

put this code in OnCtlColor ().
This wil give you desired output.
