Right. So I am having problems transferring the data from the vector to the list.
How do I work around doing that in my case? I tied casting, it compiled but the application crashes at runtime.
Thanks.

That's impossible to tell since I know nothing of either of those two classes. For example, how would you copy a vector of Automobile objects to a list of Animal objects?

That would not work unless the two classes had a "is a" relationship.

Reading that it occurred to me that a more casual (possibly less informed) reader might look at that, pause, and then have their head explode.

I'm not an STL expert, but after a quick google (bing did not give valid answers in the first few pages), here are a couple of solutions (adapt to your particular situation)
std::copy (v.begin (), v.end (), std::back_inserter (l))
or
std::list<int> l(v.begin(), v.end());
or ...

So you binged it, but it bonged out?

Just so you know, std::vector and std::list have nothing to do with MFC. They are part of STL or Standard Template Library and are cross platform.

Hello,
I am porting a Dialog based application that I used Lcc-Win32 to develop over to Visual C++.
How to I get the handle of my Dialog box?
Thanks in advance for your help.

That question confuses me. What am I missing Dave? Just curious.

So I can use existing code in an application that I developed using Win32 APIs. i.e.SendMessage(HWND, ID, wparam, lparam)
MFC "Hides" this from me.
However, if I am taking off in wrong direction I would appreciate some guidance here.
Thanks

If you wanted to send a message to some edit control, you could use:
m_edit.SendMessage(WM_GETTEXTLENGTH, 0, 0); or
::SendMessage(m_edit.GetSafeHwnd(), WM_GETTEXTLENGTH, 0, 0); or
m_edit.GetWindowTextLength();

You have struck upon one of the problems I have using MFC.
What does m_edit mean and where can I find a list of all the m_whatever?
Thanks

It's just an arbitrary name I chose for that code snippet. You may call it whatever you wish.

Is it the name I assign using the class wizard?

Wow!
I can't wait to try it.
I just love this website!
Thanks.

If it's your dialog, you probably have a variable assigned to it.
YourDialog dlg;
or
YourDialog* pDlg;
pDlg = new YourDialog;
after you create the dialog (Create), you could do something like
HWND CWnd::GetSafeHwnd( ) const;
to get the handle to the dialog.

MFC does not expose the handle to me, or does it?
Thanks for fast replies!
|

Well, GetSafeHwnd() returns a safe handle to the dialog window.
do you need something more ?

|
|
|
|
|
HWND hwndDlg = GetSafeHwnd();
Is it really that simple?
How does GetSafeHwnd() know which window you wish the handle of?
Thanks

It's called in the context of a CWnd object.

associate a class with dialog and use object of that class to access dialog.
