I would like to handle LVN_DELETEITEM in my subclass:
class DailyProgramListView :
public ATL::CWindowImpl<DailyProgramListView, WTL::CListViewCtrl, ATL::CWinTraitsOR<LVS_REPORT | LVS_SHOWSELALWAYS | LVS_SINGLESEL>>,
public WTL::CCustomListViewDraw<DailyProgramListView> {
BEGIN_MSG_MAP_EX(DailyProgramListView)
MSG_WM_CREATE(OnCreate)
MSG_WM_SIZE(OnSize)
REFLECTED_NOTIFY_CODE_HANDLER_EX(LVN_DELETEITEM, onDeleteItem)
NOTIFY_CODE_HANDLER_EX(LVN_DELETEITEM, onDeleteItem)
CHAIN_MSG_MAP_ALT(WTL::CCustomListViewDraw<DailyProgramListView>, 1)
DEFAULT_REFLECTION_HANDLER()
END_MSG_MAP()
};
For some reason, the LVN_DELETEITEM is still only posted to the parent of the listview.
The parent has REFLECT_NOTIFICATIONS_EX() in its MSGMAP.
Happy coding,
Philipp Kursawe

Dears,
Please see the below code.
int main(int argc, char* argv[])
{
int* p = new int;
*p = 0;
int& k = *p;
k = 15;
return 0;
}
Doubt is regarding the reference usage as specified in int& k = *p;.
Actually this code works fine. But I want to know whether this code is OK or not. I mean whether any issues will happen in future.
Thanks in advance,
Krishnakumar

In respect of what? Since this code effectively does nothing it's impossible to guess what issue you are facing.

Actually i wrote the sample code here.
I want to use similar code in one of my projects.

Hi all!
I am developing an add-in for Word 2003. It can insert a bitmap into .doc file after some operations by user.
Question:
When I insert only one BMP into .doc file, the picture can display correctly. If more than one BMP inserted, the picture can't displayed after save and re-open. I research this problem and find that the method named "InPlaceActivate" is called while only one BMP inserted. If more BMPs are inserted, this method can't be called. I am not sure which interface owned this method. So I research the interfaces be queried in both scenery. The different between them is that the interface as "IID_IOleXXX" will be queried if I add only one BMP. If I add more BMP into .doc file, those interfaces as "IID_IOleXXX" aren't be queried. Then the BMP can't be displayed. I think this is the reason. I try to resolve it by many ways. But all failed. Is there anybody could be kind to help me? Thank you!
Best regards!

Hi
I just wanted to replace a '%' character in CComBSTR with "%%". But the code does not support CString. The solution should be UNICODE support.
Any methods to perform this operation ?
Thanks In Advance.

CComBstr class doesn't have a method to replace a sub-string with another or to insert another string in specified position. All you can do is, get BSTR which is wrapped in CComBSTR class ( either by m_str member or by operator BSTR). You need to copy this to another CComBSTR. You may use its Append() method or overloaded += operators for ease.
CComBSTR str("here%are%percentages%");
CComBSTR newstr;
WCHAR split[] = L"%";
WCHAR* pos = wcstok(str.m_str, split);
while(0 != pos) {
newstr.Append(pos);
newstr.Append(L"%%");
pos = wcstok(NULL, split);
}
NOTE:
I would like to remind that BSTR data type has preceding header components, and the final string is terminated with double null characters. This is how system allocates memory for BSTR. There can be embedded single null characters in BSTR string data. In that case, wcslen() and wcstok() functions won't work as expected. Use CComBSTR::Length() or SysStringLen() to get length of string. You may need to examine each character in string till you find two continuous '\0' characters. During this, whenever you find a '%' add an additional '%' more tho the new string. 
Unicode support is completely ensured.

or ...
CComBSTR str("here%are%percentages%");
CString workingString(str);
workingString.Replace(_T("%"),_T("%%"));
str=workingString;

Its ok. But I guess you didn't notice "But the code does not support CString" in the actual question

Hi
I have an MFC Dialog which contains an ActiveX control ( a small grid control developped en C# with DevExpress )
The problem appears when switch to an other application or screen until editing a row in this grid ( the cursor is inside the zone edit ).
i.e : when cursor in the edited row and switching screen -----> problem of crash ( i can't get the dialog again ; i click on the try icon but no result).
I tried to impliment the Onkillfocus()
void CApp_ToolDlg::OnKillFocus(CWnd* pNewWnd)
{
CWnd *pWnd = GetDlgItem(IDC_AXSEE_PLMPC1); // GET THE CWND OF ACTIVEX CONTROL
if( pWnd != NULL)
pWnd->SetFocus(); // TRY TO SET FOCUS ON IT
CDialog::OnKillFocus(pNewWnd);
}

I've used VS2010 to create C++ MFC app and MFC ActiveX component. The ActiveX accumulates data and I need to design a method that allows the MFC app to access it.
The data is stored in std::vector using struct.
I'm told there is no direct way to do this so should I store the data differently and/or how can I access it using an ActiceX method?

If the ActiveX control is running in the same process as the app, then there's nothing stopping you from making an interface method that returns a vector<your_struct>*. If they're in different processes, then you can't return a pointer directly to the vector. If you are using the built-in marshaler, you'll need to convert the data to OLE Automation-compatible types. That means making a SAFEARRAY that contains... well, I'm not sure. I've never had to make the OLE equivalent of a struct, so I don't know how you do that off the top of my head. Hopefully this is enough info to get started.

Uhu, I have not been working with C++ in a few years, only C#, ouch I have forgotten a lot...
Right now I'm working on a COM Object and I need to sign it so it will work with no warnings at my clients.
I do have a code signing cert, but I have totally forgotten how to do it.
Is there a new and easy way using VS? I'm running VS 2010.

The two SDKs I have on this machine both have a signing app called signtool.exe. I also remember seeing some other signing app in an older SDK that had a wizard to lead you thru the process.

I'm making an COM object (ATL Simple Object) and it works fine from a C# Project, and from ASP Server Side.
But when I try to create it from JSCript in a browser, with new ActiveXObject(), I get an error saying "Microsoft JScript runtime error: Automation server can't create object"
Any idea what to do?

Hi all!
Now I am developing an add-in application. I had instantiated a sub-class of COM to expose the interface to Word. Then I add some commandbar buttons on the command bar. When user click a specified button, a data will be inserted into word document. The data inserted is created by an object of another class of mine, which is derived some interfaces of Word. This class can handle the event come from Word application.
When the data was inserted, user can right-click on it. Then a pop-up menu will be displayed. When an item was chosen, I need to disable the button on command bar.
Problem: I don't know how to control the button within data class. I had tried to transport the pointer of button into data class. But no appropriate way to implement it. I want to write a method and expose it as a member of interface. But I can't find a appropriate type to transport Office::CommandBarButton. I try to use IDispatch* to do it. But the code to convert and save the pointer can't through compilation. I don't know what I can do now. Is there some one can help me? Thank you!
Sincerely.

Hello!
I have a CTabViewImpl set as the client in a CFrameWindowImpl. I wonder how its possible to get WM_COMMAND messages from the active tab page's dialog.
When I have the same dialog template used in a modal dialog, the IDOK and IDCANCEL buttons placed in the template generate the appropriate WM_COMMAND messages.
However, when I use the dialog template as a page in the CTabViewImpl the WM_COMMAND messages are no longer generated. Usually a press on ESC oder RETURN generate the WM_COMMAND messages. Any way to have this mechanism work in embedded, non-modal dialogs too?
Happy coding,
Philipp Kursawe

Then possibly you won't be getting WM_KEYDOWN messages in page. Are you getting it?

Hi Philipp,
In your dialog message map add FORWARD_NOTIFICATIONS() to forward the WM_COMMAND (and some other) messages to the dialog's parent, ie your CTabViewImpl based window. CTabViewImpl in turn will forward (if not handled) the same messages to it's parent, see CTabViewImpl message map.
cheers,

What I want to achieve is that my tabbed windows use the IsDialogMessage to behave as if they were dialogs.
So I have implemented a handler for WM_FORWARDMSG in each of my tabviews windows.
In my MainFrame I call tabview.PreTranslateMessage() which correctly forwards the message to the current active tab window.
My CWindowImpl of each tab window has this:
MESSAGE_HANDLER_EX(WM_FORWARDMSG, OnForwardMsg)
LRESULT OnForwardMsg(UINT uMsg, WPARAM wParam, LPARAM lParam)
return IsDialogMessage((LPMSG)lParam);
}
However, pressing the VK_RETURN or VK_ESCAPE key does not result in a WM_COMMAND message being sent to the tabviews window.
Happy coding,
Philipp Kursawe
