Hi there

Tell me this is NOT true! How can the maximum array size only be 1035720 (0xfcdc8)?

Are you talking about static arrays or dynamic?

[EDIT]
Static arrays are limited by the size of the stack which is usually 4 MB (I think). Dymanic arrays are limited by the largest addressible block on the heap which is less than 2GB and depends on what addresses your program / dlls load at..

Static, but now I release I need a 64-bit PC DAMMIT!!!

I'm trying to do an analysis of a "transformation" to see how many instances of a unsigned int exists, hence the need for a "32-bit" sized array. I thought about going bitwise (just to get an off or on state) too, but still no luck.

O well back to the abacus/tickertape/punchcards/etc. And they say PC are Turing complete....(ok thats debatable, with hard work anything can be done).

How about a sparse array? I assume you will have no where near 4 GB of data?

I just need the "space" to see if what I am attempting to do is viable or not. In fact, the input is only 16bits.

CListCtrl - lost sel on postmsg DBLCLK

Looks like you're allocating an array on the stack. That probably won't work because the stack size is limited. To get an array that big you'll have to allocate the array dynamically.

With a simple CListBox I can SetCurSel() then from another routine

pWnd = GetDlgItem(IDC_LIST_BOX);
pWnd->PostMessage(WM_LBUTTONDBLCLK);

and in the handler for double click I can GetCurSel() and all is well.

If I get fancier with a CListCtrl (In Report style)
and programatically set a row to selected,

when I pWnd->PostMessage(WM_LBUTTONDBLCLK); to the ListCtrl

in the double click handler there is no longer a selected item

nItem = pMyListCtrl->GetNextItem(-1,LVNI_SELECTED); returns -1 but anytime before the
PostMessage() it is returning the correct selected row.

Anyone have a clue about this?

Sending a WM_LBUTTONDBLCLK like that won't do anything. This is because you haven't specified the position where the mouse is double clicked (look at the documentation for the WM_LBUTTONDBLCLK message). It appears to work for a list box, because a list box never removes the selection. If a click doesn't hit anything, it doesn't change the selection. However, for a list-view control, if a click doesn't hit anything, then the selection is removed, hence GetNextItem(-1,LVNI_SELECTED) returns -1.

Hope this helps,

Ryan

Thanks Ryan!

I've implemented the following and it is working great!
// Setup a post message with mouse x&y pointed to the selected item

pListCtrl =
(CListCtrl *)pThis->GetDlgItem(IDC_LIST_OPTION_SOURCES_REPORT);
pListCtrl->GetItemRect(pThis->m_OptionSourcesIdx,&rect,LVIR_BOUNDS);

lParam = MAKELPARAM(rect.left,rect.top);
pListCtrl->PostMessage(WM_LBUTTONDBLCLK,0,lParam);

I see you also were most helpful to others that night answering posts all night long! Great job - you efforts are most appreciated!

At the moment I'm trying to write an Office XP (specifically PowerPoint) add-in based on the excellent article by Amit Dey http://www.codeproject.com/com/outlookaddin.asp[^]

When I try to use the import directive to add MSO.DLL to the project I get the following linker error.

StdAfx.obj : fatal error LNK1179: invalid or corrupt file: duplicate comdat "_IID_CanvasShapes"

The build environment is VC6 SP5, with Office XP, SP1.

Any Ideas? Smile | :)

I would like to create a COM object with all my ADO methods. I then would like to have Visual Basic pass a recordset pointer to my COM DLL. Is this possible? If so how would I go about it?

Thanks

Hi,

I am developing an application with Visual C++ 6.0.

In the Visual C++ IDE, I can run my application in debug mode.

However, I can't run it in release mode.

How can I correct this behavior ?

Thanks,

Claude

Hi,.

I have a Visual C++ 6.0 application. I have saved numerous files with this
application with the Doc/View architecture of MFC.

I want to add variables to save and retreive. I know that we can have
version number in the context of serialization with IMPLEMENT_SERIAL(CMyDoc,
CDocument, version).

Does it creates a problem to change DECLARE_DYNCREATE to DECLARE_SERIAL in
the CMyDoc ?

Thanks,

Claude

No, it should work just fine. DECLARE_SERIAL() incorporates DECLARE_DYNCREATE() plus serialisation.

Multiple Doc Templates

Hi,

I wish to have two different views of the document (in a MDI app) but with different menus for each view.

I basically want to use a class A and use it for different methods. Each method
would require a different view and different options - hence a new menu system.
I have two class extensions of the view and do AddDocTemplate for each new template.
However it only brings up the dialog to choose the view if the IDR menu resource is the
same.

When I use the same menu for each call to new CMultiDocTemplate it works as wanted
except that the menu is the same. I don't want to dynamically carve the menu at runtime
so there must be any easier way.

Does anyone know what I am doing wrong?

Regards,

flip

I've used a solution from an article on this site: http://www.codeproject.com/docview/replacingview.asp[^]. To change the menu as well, just call AfxGetMainWnd()->SetMenu(pMenu).

Hope this helps,

Ryan

Thanks Ryan.

That worked. I just put
HMENU hMenu = ::LoadMenu(NULL,MAKEINTRESOURCE(IDR_MYNEWMENU));
::SetMenu(AfxGetMainWnd()->GetSafeHwnd(),hMenu);
::DrawMenuBar(AfxGetMainWnd()->GetSafeHwnd());

in OnInitialUpdate() in the (second) doc.

I just mistakenly thought that specifiying a unique view and a unique menu resource in an MDI app with document templates should work the way I intended.
