I'm not sure if you've looked at COleDateTime[^] class. Unsure | :~

These attempts all work:

int d,m,y;

// ASCII variant
sscanf("14.06.1955", "%d.%d.%d", &d, &m, &y);
printf("%d/%d/%d\n",d,m,y);

// Unicode variant
swscanf(L"14.06.1955", L"%d.%d.%d", &d, &m, &y);
printf("%d/%d/%d\n",d,m,y);

// TCHAR variant
_stscanf(_T("14.06.1955"), _T("%d.%d.%d"), &d, &m, &y);
printf("%d/%d/%d\n",d,m,y);

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

Hi,

I am developing an application in which i want to know whether an Enter key is pressed, if so want to show the user Edit window for that particular entry in ListView.Is there any way to get the NM_RETURN notify event from CListCtrl. I am using VC++ to develop the application.

thanks

To do this, the list-view needs to tell the system that it'll process all keys it's sent (which it can do when it's sent the WM_GETDLGCODE message)

Easiest way is to sub-class the list control and add an OnDlgCode override, like this:

// In header
class ListControlThatSendsNM_RETURN : public CListCtrl
{
   DECLARE_MESSAGE_MAP();
   UINT OnGetDlgCode()
};

// In .cpp file
BEGIN_MESSAGE_MAP(ListControlThatSendsNM_RETURN, CListCtrl)
   ON_WM_GETDLGCODE()
END_MESSAGE_MAP()
UINT ListControlThatSendsNM_RETURN::OnGetDlgCode()
{
   return DLGC_WANTALLKEYS;
}

then you can use ListControlThatSendsNM_RETURN instead of CListCtrl in MFC dialogs and the dialog will be sent NM_RETURN notifications.

Thanks you alot. This is the Answer.
Without overriding this function, the NM_RETURN or WM_KEYDOWN wont get sent, and you need to both Press Mouse button AND Enter key to have those messages sent. With this overrided function, you only need to press Enter key.

One more note I found useful is that: If u r not using CListView, but have a Pane (DockablePane) who is the parent of the CListCtrl; and you want the Pane to handle Notify Messages from the CListCtrl. The best way to do is:

1) Override your CListCtrl, and handle ON_NOTIFY_REFLECT_EX( notifyMessage, memFunction) (notifyMessage could be NM_RETURN)
2) In memFunction, just return FALSE. Which allows this notifyMessage will be handled in other places as well( for ex CListView's Parent).
3) In the Parent class (DockablePane), handle ON_NOTIFY(notifyMessage, ChildID, memFunction)

Thanks you

Is there any way to increase the Height of treeview control's items?

Thank You.

As I am working on Windows Mobile 6.0 Application. It is not working for me.

Thank you, is there any other solution?

There's a Treeview.ItemHeight property which you can set - hopefully that's available on Win Mobile as well.

There are three kinds of people in the world - those who can count and those who can't...

No such a property available on windows mobile.

Ah - sorry. It may have been removed on the mobile platform to keep the control layout consistent.

You've been asked numerous times to read the two part series that explains about strings and yet you come back asking how to convert a CString to [insert stuff here]

The Complete Guide to C++ Strings, Part I - Win32 Character Encodings[^]
The Complete Guide to C++ Strings, Part II - String Wrapper Classes[^]

I am sure you read neither of them, not even once. Hmmm | :|

Something like this:
CString str; // init'd this already somewhere
wchar_t *wCharBuff = new wchar_t[strlen(str)+1];
wcscpy(wCharBuff,str);

You need to google first, if you have "It's urgent please" mentioned in your question.

1? If it were Unicode (which it is), then it must be 2! Or rather sizeof(TCHAR)*1, which is the neutral way of manipulating it.

You were also using strlen with a Unicode string in your answer to the OP!

You're both assuming UNICODE is defined and not defined.
