expression ?

do you mean exception ?

if you're getting an unhandled exception, the easiest way to find out what it is is to.. handle it.

try
{
... do something
}
catch (CException *e)
{
   e->ReportError();
}

I have just realised that the exception occurs in the block of code:
it comes up after running for sometime...

// Load the rows <br />
pRange = pSheet->GetRange( _bstr_t("A3"), _bstr_t("CQ9990") );<br />
<br />
for ( int iRow = 1;iRow <= N; iRow++)<br />
{<br />
for (int iColumn = 1; iColumn < N2; ++iColumn )<br />
{	<br />
_variant_t	vItem = pRange->Item[(long) iRow ][ (long) iColumn];<br />
_bstr_t	 bstrText( vItem );<br />
raw_data[iRow][iColumn] = vItem;<br />
<br />
}<br />
}

And... what do you want ? Smile | :)

(could you write some formula, like: C[i] = A[i] | B[i] ?)

i want if A[i]={a,c,e,d}

and B[i]={a,c,f,g}

than result is C[i]={a,c,d,e,f,g}

If the array are sorted (like the sample posted) then your task is almost trivial.

OK, I see array A is actually NOT ordered.

I guess it doesn't work even for sorted arrays (I suppose you should use two different indices).

The following function works (at least I suppose it does...) with increasing-ordered arrays (without duplicate items):

// merges arrays 'l' and 'r' into 'o'.
// precondition: 'l','r' should be increasing-ordered, (without duplicate items).
void MergeArrays(CUIntArray & l, CUIntArray & r, CUIntArray & o)
{
  int il = 0, ir = 0;
  int lcount, rcount;
  lcount = l.GetCount();
  rcount = r.GetCount();
  o.RemoveAll();
  for (;;)
  {
    if ( il == lcount)
    {
      if ( ir == rcount) return;
      o.Add(r[ir]);
      ir++;
    }
    else
    {
      if ( ir == rcount)
      {
        o.Add(l[il]);
        il++;
      }
      else
      {
        if (l[il] < r[ir])
        {
          o.Add(l[il]);
          il++;
        }
        else if (l[il] > r[ir])
        {
          o.Add(r[ir]);
          ir++;
        }
        else
        {
          o.Add(l[il]);
          il++; ir++;

I prefer the precondition, since it makes the merge function acting on homogeneus arguments.

CUIntArray does not provide a 'Merge' method hence you have to write your own.

One possibility would be to merge them together, and then use std::unique() with erase(). Without actually trying it, however, I can't say for sure.

Which is why I used the word possibility. It would require him to get the contents of the CUIntArray moved to an STL container first.

Yes, it is a nice idea. My 'unfortunately' was in fact a subtle suggestion (too subtle, I guess) to discard the MFC class.

Marquee Progress Control

Hi,

I am tring place a progress bar on dialog and make it Marquee Progress Control in win32. I tried with some code in InitDialog ():

HWND hwndProgress=GetDlgItem(m_hwnd,IDC_PROGRESS1);
::SetWindowLongPtr(hwndProgress,GWL_STYLE,PBS_MARQUEE);
::SendMessage(hwndProgress,(UINT) PBM_SETMARQUEE,(WPARAM) TRUE,(LPARAM)50);

But Progress bar is not visible. If I comment SetWindowLongPtr(), progess bar visible but not marquee.

Plz guide.

Try it

HWND hwndProgress = GetDlgItem(m_hwnd, IDC_PROGRESS1);
LONG_PTR lStyle = ::GetWindowLongPtr(hwndProgress, GWL_STYLE);
lStyle |= PBS_MARQUEE;
::SetWindowLongPtr(hwndProgress, GWL_STYLE, lStyle); 
::SendMessage(hwndProgress, PBM_SETMARQUEE, WPARAM(TRUE), LPARAM(50));

Thanks for reply but above code is working with MFC application but not win32 application.

In win32 Only blank Progress bar is coming.
I am using VS 2005.

Any help?

Try to change the control line in your .rc file:

CONTROL         "",IDC_PROGRESS1,"msctls_progress32",PBS_MARQUEE,7,7,156,14

...and then send only the PBM_SETMARQUEE message in your init scope Smile | :)

If I change It display error:

error RC2104 : undefined keyword or key name: PBS_MARQUEE

I defined the PBS_MARQUEE in resource.h , error is not coming but progress bar is still empty and not in marquee mode.
