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? Smile | :)

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?

Print in an SDI application

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 ?

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.

// Get the active view.
CFrameWnd* pFrameWnd = (CFrameWnd*)AfxGetApp()->GetMainWnd();
CView* pView = pFrameWnd->GetActiveView();

if( pView != NULL )
{
    // Send Print message. 
    // If you want to print directly, then change ID_FILE_PRINT to ID_FILE_PRINT_DIRECT.
    pView->OnCmdMsg( ID_FILE_PRINT, 0, 0, 0 );
}

Regards,
Jijo.

Showing image in List control

Thank you, I think this is exactly what I was looking for Smile | :)

I'm inside my view anyway, so

this->OnCmdMsg( ID_FILE_PRINT, 0, 0, 0 );

does exactly what I want Smile | :)

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.
