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.

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

I have a base template class
template<class T, UINT titleId, int SortIndex, class WindowClass = ATL::CWindowImpl<T>>
class ATL_NO_VTABLE ITabPageImpl : public WindowClass {
BEGIN_MSG_MAP_EX(ITabPageImpl)
MSG_WM_CREATE(onCreate)
MSG_WM_DESTROY(onDestroy)
REFLECT_NOTIFICATIONS_EX()
ALT_MSG_MAP(1)
NOTIFY_CODE_HANDLER_EX(LVN_DELETEITEM, onModifyTable)
END_MSG_MAP()
ITabPageImpl() : _table(this, 1) {}
private:
ATL::CContainedWindowT<WTL::CListViewCtrl> _table;
In the onCreate method I subclass a control, if the implementation provides a specific method:
__if_exists(T::getTableControl) {
_table.SubclassWindow(static_cast<T*>(this)->getTableControl());
}
However, after subclassing the message loop of T produces an assertion when the subclassed control is supposed to process its first message.
The basic Idea is, that I want to put handling of certain messages in the base class and lift the burden on implementation classes.
Thanks for any help!
Happy coding,

Hi Philipp,
You are misunderstanding ATL::CContainedWindow operation. Post on the WTL support list[^] for help.

Thanks Alain for your reply!
Maybe I should describe what I want to achieve: I want to subclass a child window and pre-handle certain messages in my class before the child window can process them itself.
I thought CContainedWindow was the way to go then?
In the particular case I want to set the background colour of the window.
Happy coding,

Hello,
I am struggling to fit CListBoxCtrl and CDoubleBufferWindowImpl together.
I have a owner drawn listbox ready, whose MSG_WM_DRAWITEM I handle in the parent control for now.
I guess the first step would be to move the MSG_WM_DRAWITEM message handling to my custom listbox control.
How would I then also fit in the double buffer technique?
My solution was something like in the DoPaint method to call the original controls DefWndProc but that does not work.
Any ideas?
Happy coding,
Philipp Kursawe

Hi Philipp,

It may be your choice but it's not the first step.
You need to use a double buffered CListBox, for instance:
class CMyListBox : public CDoubleBufferWindowImpl<CMyListBox, CListBox, ATL::CControlWinTraits>
{
BEGIN_MSG_MAP(CMyListBox)
CHAIN_MSG_MAP(CDoubleBufferWindowImpl)
END_MSG_MAP()
void DoPaint(HDC hdc)
{
DefWindowProc(WM_PAINT, (WPARAM)hdc, 0);
}
};
If you subclass the listbox in your parent dialog OnInit(), you can check with breakpoints that the dc referenced in your DrawItem() member is the MemoryDC set in CMyListBox::DoPaint().
My test code:
class CTest0View :
public CDialogImpl<CTest0View>,
public COwnerDraw<CTest0View>
{
public:
enum { IDD = IDD_TEST0_FORM };
CMyListBox m_lb;
void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
return;
}
BEGIN_MSG_MAP(CTest0View)
MESSAGE_HANDLER(WM_INITDIALOG, OnInit)
CHAIN_MSG_MAP(COwnerDraw<CTest0View>)
FORWARD_NOTIFICATIONS()
END_MSG_MAP()
LRESULT OnInit(UINT , WPARAM , LPARAM , BOOL& bHandled)
{
m_lb.SubclassWindow(GetDlgItem(IDC_LIST1));
m_lb.AddString(L"Titi");
m_lb.AddString(L"Tata");
m_lb.AddString(L"Toto");
return bHandled = FALSE;
}
};
cheers,
AR

Thanks Alain, this works (almost)!
I am using your WTL::CControlDialogImpl to show the listbox in a modal dialog. The drawing is a little off now.
void OnDrawItem(int nIDCtl, LPDRAWITEMSTRUCT item)
if (item->itemID == -1) return;
WTL::CDCHandle dc(item->hDC);
dc.GradientFillRect(item->rcItem, RGB(200,200,200), RGB(10,10,10), false);
if (item->itemState == ODS_FOCUS) {
dc.SetTextColor(RGB(255,255,255));
} else {
dc.SetTextColor(RGB(255,255,255));
}
WCHAR text[1024];
int chars = m_Ctrl.GetText(item->itemID, text);
dc.SetBkMode(TRANSPARENT);
dc.SelectFont(font);
dc.DrawText(text, chars, &item->rcItem, DT_NOPREFIX | DT_SINGLELINE | DT_CENTER | DT_VCENTER | DT_END_ELLIPSIS);
}
After some rows the gradients stop to show up and the background is just the standard window color.
Happy coding,

Hi, everyone!
I had encounter a problem while I am developing a add-in for Word. I make a class derived from IViewObject and implement my own OnDraw. In OnDraw, I create a compatible DC from the parameter with OnDraw whose type is ATL_DRAWINFO. But the compatible DC can't be created correctly in most time. The error code I get is 183 (The file is existed and it can't be created). I don't know the reason. I guess maybe Microsoft don't allow others to do that, isn't it?
After then, I try to get a DC by GetDC or GetWindowDC. But the object I draw through them isn't in the client area of Word. Maybe I need to get the DC of Client-area of Word. But I don't know how to get it. Even I doubt whether the DC of Client-area is exist. I hope someone could be kind to tell me how to resolve this problem. Thx!

Hi all
I have a problema with MDITabbedControl.
- Open multiple MDI tab screens
- Select a tab from one of them and start moving it. Drop it on the "X" thing that closes the screen from another tab
- Now move your mouse over the other tabs. As the mouse passes over the tab, the tab still captured, mouse doesn't release the capture.
I try overloading pretranslatemsg, catching the message WM_LBUTTONUP, but still happens when during a drag/drop I click on close button.
This is my code:
switch (pMsg->message)
{
case WM_LBUTTONUP:
{
CWnd* pWnd = FromHandle(pMsg->hwnd);
CMFCTabCtrl* tabGroup = dynamic_cast<CMFCTabCtrl*>(pWnd);
if (tabGroup)
{
CPoint clickLocation = pMsg->pt;
tabGroup->ScreenToClient(&clickLocation);
int tabIndex = tabGroup->GetTabFromPoint(clickLocation);
if (tabIndex >= 0)
{
CWnd* pTab = tabGroup->GetTabWnd(tabIndex);
if (pTab && tabGroup->IsTabCloseButtonHighlighted() && tabGroup->IsTabCloseButtonPressed())
{
pTab->SendMessage(WM_CLOSE, 0, 0);
}
}
}
break;
}
default:
{
break;
}
}
return CMDIFrameWndEx::PreTranslateMessage(pMsg);

In Multiline Edit control, a new line to be formed form after ALT+ENTER instead of Enter, this has similar behaviour has IM messengers etc., how can I enable the same, I learned the Keyboard virtual keys, VK_MENU for ALT ; VK_RETURN for Enter,(PreTransalateMessage ()) Pls., let me know the combinations to form a new line.
PreTranslatemessage()
<...
// ENTER key
if( (( pMsg->message == WM_KEYDOWN ) && ( pMsg->wParam == VK_MENU ) )
||( ( pMsg->message == WM_KEYDOWN ) && ( pMsg->wParam == VK_RETURN )) )
{
//Enter key was hit -> do whatever you want
// ProcessEnterkey();
/*m_wndCMDWnd.GetLine((nIndex,lpszBuffer);*/
return TRUE;
}
above code is valid for <<enter>>, but the same should be working for <<alt+enter>> ie., form a new line , Pls., let me know how to accomplish the same.
|

|

Alt key combination is treated as system key which cannot be handled by WM_KEYDOWN. Use WM_SYSKEYDOWN Message instead.
if (pMsg->message == WM_SYSKEYDOWN)
{
if( pMsg->wParam == VK_RETURN)
{
}
}

Is this a homework?
What is difficult in this or what is the thing that is stopping you from going ahead and finishing off the assignment.
Start coding, and post your code in case you face any issues and then someone here might help you.
Also, as per the forum guidelines this is not the correct forum for posting this question.

In that case get on with it yourself rather than expecting someone else to do it for you.
I must get a clever new signature for 2011.
