Are you sure? How are you verifying that?
What code are you using to create your custom control class?
If the controls are in a dialog, how are you associating your
custom control class with a control on the dialog?
I tested on a dialog by adding this member to the dialog class
CReflectedListCtrl m_ListCtrl;
and associating it with a ListView control on the dialog resource by
adding this to the dialog class' DoDataExchange()
DDX_Control(pDX, IDC_LIST1, m_ListCtrl);

I called a message box from within the constructor of CListCtrl-derived class for which I declared two objects in its parent dialog class, and on both of their construction, I get this message box twice. That's how I ensured.

That covers the C++ object....you also need the HWND object.
Again, how are you associating the control with the C++ object?

I am subclassing both CListCtrl-derived class and the Combo box objects.

Sorry if I haven't answered your last question. The thing is, that subclassing is used in case of CListCtrl-derived class, the reason why I don't see its varible entries inside DoDataExchange, hence the problem. That means the requirement is that of making LBUTTONDOWN and LBUTTONDBLCLK work with subclassed windows of CListCtrl-derived class. Can you help me out with this?
Thanks in advance.

You have to add the entries to DoDataExchange if they are not there.
If the listview controls are in the dialog resource, you can use the wizard
to add a control variable. It will add an entry like
DDX_Control(pDX, IDC_LIST1, m_ListCtrl);
Change m_ListCtrl's type to your derived type in the header file.
Then the control will be subclassed.
From my previous working sample code:
CReflectedListCtrl m_ListCtrl;
void CMyDialog::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
DDX_Control(pDX, IDC_LIST1, m_ListCtrl);
}

In which case CWnd::SubclassWindow(HWND DocumentList) fails? Even though, the variable HWND DocumentList which I am using as its parameter is locally declared and initialized where I am calling SubclassWindow, still SubclassWindow is failing(Debug Assertion Failure!). What is its remedy? Could u please suggest?
DocumentList parameter is declared and initialized some lines before calling SubclassWindow, as following:
HWND DocumentList = CreateDocumentList(parenthandle, rect.left, rect.top, rect.Width(), rect.Height(), someflag) ;
Line 1
Line 2
Line 3
SubclassWindow(DocumentList) ; // which fails here, why?

I got the answer of why SubclassWindow was failing, it was because I had DDX_Control entries inside DoDataExchange function, which shouldn't be there, otherwise the parameter to SubclassWindow will always be attached to the parent dialog box, which doesn't fit its criterion. But now after that, the messages WM_LBUTTONDOWN and WM_LBUTTONDBLCLK should run, which are not running. That means my question is, after calling CWnd::SubclassWindow function, why these two messages do not respond at all?Please suggest some remedy.

Why are you calling SubclassWindow?
If you're using MFC you very rarely need to explicitly call it.

Where is this code called from? You really need to provide a context.
If SubclassWindow is the CWnd SubclassWindow method, then what's the class you are
calling it from?

Why don't you step into the function with the debugger and find out?

I have a method in CListCtrl-derived class, from where I am calling CWnd::SubclassWindow, and after calling that, WM_LBUTTONDOWN and WM_LBUTTONDBLCLK do not get called at all.

You still haven't answered WHY you are calling SubclassWindow.
Where do the CListCtrl derived objects come from? Show some code.

CListCtrl derived objects come from the parent class, i.e. the dialog class, I call one member function of CListCtrl-derived class, SubClassMyList, in which I am calling SubclassWindow(HWND) function, after which mouse events don't work on this derived class.
Sorry, I was away for some days, hence couldn't update you quickly.

I don't know how many times I've asked why...
All my MFC controls for the past decade have got mouse messages just fine without calling subclassWindow...

Dear Mark,
First of all, I am very sorry if I have tested your patience, although unknowingly and unintentionally. I have some big code of my project, which was running fine in Visual C++ 6.0(in which it was first written), but which I now needed to convert to Visual C++ 2005. After everything I have explained till date, since the functionality(mouse events) after conversion is not running in VC 2005, I created my own MFC application in VC 2005, in which, like the project code, I tried using CWnd's SubclassWindow(HWND). Since this functionality was running in VC 6.0, I need to keep and also make it run in VC 2005. Hence the inclusion of SubclassWindow also in my code(the sample application which I am trying these things in). I hope I am very much clear this time. Could you please help?

Hi,
In my MFC SDI application, there is a "File | Print" automatically created from the wizard which prints my CHtmlView successfully.
Now I would like to issue this command *manually* from my view.
Which method do I need to call?
Thank you!
|
|
|
|
|
Is ShellExecute (with verb "print") helpful ?
Regards,
Paresh.
|
|

|

Hi,
I do not think so; I have dynamic HTML code written to my CHtmlView which I want to print the same way as with File | Print.
I tried a little bit with ShellExecute but it does not work as expected.
Regards,
Niki

Use this code snippet to print your view from anywhere. The core idea is to call CView::OnCmdMsg() by passing ID_FILE_PRINT or ID_FILE_PRINT_DIRECT.
CFrameWnd* pFrameWnd = (CFrameWnd*)AfxGetApp()->GetMainWnd();
CView* pView = pFrameWnd->GetActiveView();
if( pView != NULL )
{
pView->OnCmdMsg( ID_FILE_PRINT, 0, 0, 0 );
}
Regards,
Jijo.

Thank you, I think this is exactly what I was looking for
I'm inside my view anyway, so
this->OnCmdMsg( ID_FILE_PRINT, 0, 0, 0 );
does exactly what I want

Niki

In the below code i have just inserted one item.
But no image appearing on the list ctrl item why?
m_ImageList.Create(IDB_IMAGES, 16, 1, RGB(255,255,255));
m_ListCtrl.SetImageList(&m_ImageList, LVSIL_NORMAL);
LV_ITEM lvItem;
lvItem.mask = LVIF_IMAGE | LVIF_TEXT ;
lvItem.iItem = 0;
lvItem.iSubItem = 0;
lvItem.iImage = 0;
lvItem.pszText = _T("New Folder");
m_ListCtrl.InsertItem(&lvItem);
|
|
|
|
|
Please check your ListCtrl is in LVS_REPORT mode then first Insert column
|
|
|
|
|
You should use LVSIL_SMALL instead of LVSIL_NORMAL if the list control is in report view.
|
|
|
|
|
Yes its working now. Thanks.
