i have a run time error in Matrix ADT
i hope u help me to find out this problem and how i can fix it
template <typename t="">
Matrix<t> Matrix<t>::Addition(Matrix<t> rhs)
{
if((rhs.numRows!=numRows)||
(rhs.numColumns!=numColumns))
{
cout<<"Rows and columns must be in same degree";
exit(1);
}
else
{
int r,c;
Size(r,c);
Matrix<t> addResult;
addResult.MemAlloc(r,c);
for(int rows=1;rows<=numRows;rows++)
{
for(int columns=1;columns<=numColumns;columns++)
{
addResult.elements[rows][columns]=elements[rows][columns]+
rhs.elements[rows][columns];
}
}
return addResult;
}
}
</t></t></t></t></typename>

So - you might be interested to know that C/C++ uses zero-based arrays, not one-based arrays?

what is the problem if i start to use from 1 index ....?? that's not the problem
i think the problem in Memory Allocation for Addition Function and Copy Function
also there is divide by zero in ToUpper() but i don't care to it
iam interesting fixing Addition and Copy Functions
thnx for your reply

Nothing soooo bad, actually, but you're wasting the first element of the array, and, of course, you've declare the array having needed itemss plus one if you don't want to go out of bounds in your loops, for instance
#define N 10;
int a[N+1];
int i;
for (i=1; i<=N; i++)
{
}

Hi all,
Here is the situation. We have this driver box that we can communicate via USB using the libraries provided by the manufacturer. The library came with a .tlb, /lib and .h file and its written based on COM model and requires ATL support. So, in VC++ I can just create a MFC application and add an ATL object, include the .h file, import the .tlb file and create CComPtr variable derived for their object for the driver and communicate with the driver through that object. Everything works fine.
But now I need to use the library that they provided in LabWindows CVI where these libraries wont work. It doesnt have ATL support. I tried creating a MFC applciaiton where it listens to the serial port and CVI sending commands to the MFC application via serial port, but this is slow.
Is there any other way where I can create something that can be added into CVI as an object without bothering about the stuff in the object other than just communicating with it within the CVI program (ActiveX??).
thanks in advance.

Usually you don't need either MFC nor ATL to cunsume COM components.
On LabWindows CVI website there are samples about using ActiveX components, see [^].

Actually its not an ActiveX object, I just thought if I can use that type to interate in CVI.
Here is what the driver manual said,
"The Driver USB Library is implemented as an object that conforms to Microsoft's Component Object Model (COM). A COM object is an instance of a COM class. Clients interact with a COM object only through its interfaces.
To create an instance of the COM object in a C++ program, include the following lines of code in your program:"
#include "..\DriverUsbLib\DriverUsbLib.h"
#import "..\DriverUsbLib\_DriverUsbLib.tlb" no_namespace
using namespace std;
CComPtr<ihostdrv> pIHostDrv;
HRESULT hr = CoCreateInstance(__uuidof(CHostDrv), NULL, CLSCTX_INPROC,
__uuidof(IHostDrv),(LPVOID *) &pIHostDrv);</ihostdrv>
I was not able to do the same thing in CVI. I tried to search on NI forums, but couldnt get any useful info on dealing with COM objects. Will keep looking on it.
thanks,
PKNT

I'm having trouble with getting search results from Active Directory since I installed Microsoft Echange. After Exchange installation the enum order changed so that child SOME objects are enumerated before parent. Before installing Exchange everything was OK. Now I want to fix this behavior with following piece of code (but currently unsuccessfull). The flag LDAP_DIRSYNC_ANCESTORS_FIRST_ORDER does not work for me.
Here is the piece of code:
void ImportComputersFromAd()
{
CComPtr<IDirectorySearch> pSearch;
HRESULT hr = ::ADsGetObject(L"LDAP://DC=mydomain", IID_IDirectorySearch, (PVOID*)&pSearch);
ADS_SEARCHPREF_INFO rgSearchPrefs[4];
DWORD dwNumPrefs = 0;
rgSearchPrefs[dwNumPrefs].dwSearchPref = ADS_SEARCHPREF_SEARCH_SCOPE;
rgSearchPrefs[dwNumPrefs].vValue.dwType = ADSTYPE_INTEGER;
rgSearchPrefs[dwNumPrefs].vValue.Integer = ADS_SCOPE_SUBTREE;
dwNumPrefs++;
ADS_PROV_SPECIFIC dirsync;
dirsync.dwLength = 0;
dirsync.lpValue = NULL;
rgSearchPrefs[dwNumPrefs].dwSearchPref = ADS_SEARCHPREF_DIRSYNC;
rgSearchPrefs[dwNumPrefs].vValue.dwType = ADSTYPE_PROV_SPECIFIC;
//rgSearchPrefs[dwNumPrefs].vValue.ProviderSpecific.dwLength = sizeof(dirsync);
rgSearchPrefs[dwNumPrefs].vValue.ProviderSpecific = dirsync;
dwNumPrefs++;
rgSearchPrefs[dwNumPrefs].dwSearchPref = ADS_SEARCHPREF_DIRSYNC_FLAG;
rgSearchPrefs[dwNumPrefs].vValue.dwType = ADSTYPE_INTEGER;
rgSearchPrefs[dwNumPrefs].vValue.Integer = LDAP_DIRSYNC_ANCESTORS_FIRST_ORDER;
dwNumPrefs++;
hr = pSearch->SetSearchPreference(rgSearchPrefs, dwNumPrefs);
LPOLESTR pszAttribute[] = { L"ADsPath"};
CONST DWORD dwAttrNameSize = 1;
ADS_SEARCH_HANDLE hSearch;
hr = pSearch->ExecuteSearch(L"(|(objectClass=computer)(objectClass=organizationalUnit))", pszAttribute, dwAttrNameSize, &hSearch);
while(pSearch->GetNextRow(hSearch) != S_ADS_NOMORE_ROWS)
{
for(DWORD x = 0; x < dwAttrNameSize; x++)
{
ADS_SEARCH_COLUMN col;
HRESULT hr2 = pSearch->GetColumn(hSearch, pszAttribute[x], &col);
if(hr2 != E_ADS_PROPERTY_NOT_FOUND // 0x8000500d - The directory property cannot be found in the cache
&& hr2 != 0x8007200a // The specified directory service attribute or value does not exist.
&& hr2 != E_ADS_COLUMN_NOT_SET //0x80005010 - The specified column in the Active Directory was not set.
&& hr2 != 0x80005008)
{
CComPtr<IADs> srpiads;
hr2 = ::ADsGetObject(col.pADsValues->CaseIgnoreString, IID_IADs, (PVOID*)&srpiads);
//pThis->AddComputerProperties(srpiads);
pSearch->FreeColumn(&col);
}
}
}
pSearch->CloseSearchHandle(hSearch);
}

I want to set Footer in every page in Excel.
i am working with excel 2003 so i m using Excel.h and Excel.cpp.

wb = wbs.Add(covOptional);
//Get the first sheet.
wss=wb.GetSheets();
ws=wss.GetItem(COleVariant((short)(1)) );
ps=ws.GetPageSetup();
ps.SetLeftHeader(_AsciiFileName);
ps.SetRightHeader( "&D" );

Oh. Someone didn't like your reply. I wonder who that could be? 
Well I liked it so I will weigh in for what it's worth.  I'm also considering helping him myself.

Ok sir, I removed ASAP. Now why are you wasting time instead of providing me the f*?#?ing code?

I have created a CFormView on which I have created a dialog and I have made the Formview Transparent using the code below:
HBRUSH CABCFormView::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CFormView::OnCtlColor(pDC, pWnd, nCtlColor);
//This code is used to make the view transparent
if( CTLCOLOR_DLG == nCtlColor )
{
hbr = (HBRUSH)GetStockObject(HOLLOW_BRUSH);
pDC->SetBkMode( TRANSPARENT );
}
return hbr;
}
but by doing this when I am moving the dialog, view is not getting refreshed and facing the paint issue...
Kindly suggest.....

You could add a WM_MOVE handler and invalidate the formview in that? Or maybe in an WM_EXITSIZEMOVE handler?
