thx for reminding this!
e.g from 'Effective STL' Item 8: Never create containers of auto_ptrs
|
|
|
|
|
frankly, i never use auto_ptr at all, anywhere. i would just use a vector of CBitmap*s.
so, Anonymous, sorry about the bad auto_ptr advice - but i was trying to get you to use CBitmap * !

Agreed, CBitmap*s is the way to go in this specific case.
I recently tried to use the MS auto_ptr and failed miserably because it doesn't implement reset(). Instead I used boost::scoped_ptr to very good effect. I plan to use it more in the future. Worth a look.

No, thanks for your help! I didn't like auto_ptr in the past and I will go back to my old code with CBitmap*

Probably the problem comes from HBITMAP, which is a handle and can't be simply "copied". If you simply copy the value of the HBITMAP, you would create a reference... which would become invalid if the original HBITMAP fades away.
I guess a CBitmap copy-ctor has to test 1. HBITMAP to be valid and 2. create a new handle by duplicating the original.
I don't know if this is possible with Win32. Perhaps not or CBitmap would already do it? Comments?
PS: Using auto_ptr of *CBitmap (rathern than CBitmap) seems to be a solution.

Hi,
Can anyone tell me how to make the enter key work like a tab key in a dialog box.
For instance, I have two edit controls, a Checkbox control and three command button controls and I pressing the enter key should setfocus to the next control according to the TAB order.
Is it possible to do this without using event handlers for each and every control?
Regards,
Seagull.

Hi.
I am implemented a very simple MFC program without the powerful of ClassWizard.
I added a CListCtrl listbox. Everything works as designed except for a double-click message handler. I cannot get the program to respond when the user double-clicks the listbox. I have tried different messages, but all failed.
I would like to know, What message do you handler for double-click (left mouse button) on a CListCtrl that is not in a dialog box and was not implemented using ClassWizard.
Thanks,
Kuphryn

Your dialog box receives the LBN_DBLCLK notification message when you double-click. You can add a command handler ON_COMMAND(LBN_DBLCLK, ...) in your parent window.

Okay. Thanks.
The program ignores all solutions yet. There is something weird going on here. I try adding a hander for LBN_DBLCLK and it only works outside of the CListCtrl box. I believe the program ignores everything inside of the list box.

The notification is sent TO THE PARENT WINDOW, that's by design.
Otherwise, you need to derive your own class, and tweak things a bit (many CP articles are here to help your way out).

You're confusing the list box and list control. CListCtrl is the latter, and sends an NM_DBLCLK message to its parent when the control is double-clicked.

Okay.
NM_DBLCLK does not work either.
I tested ON_NOTIFY and ON_NOTIFY_REFLECT using NM_DBLCLK and LBN_DBLCLK.

Okay. I figured out the bug. The bug was a human-error, not an MFC error.
I made an error during creation of the CListCtrl object.
Here is the error.
// Here is the incorrect creation code.
-----
m_LB_Box.Create(WS_CHILD | WS_VISIBLE | WS_BORDER | LVS_REPORT | LVS_SORTASCENDING, CRect(0, 100, 100, 50), this, 1);
-----
Notice the "1" in the last parameter.
// Here is the solution.
-----
m_LB_Box.Create(WS_CHILD | WS_VISIBLE | WS_BORDER | LVS_REPORT | LVS_SORTASCENDING, CRect(0, 100, 100, 50), this, IDC_LB_BOX);

Thanks everyone,
Kuphryn

Hey all. I'm working on a MFC Single Doc program. I have included:
<br />
m_pMainWnd->ShowWindow(SW_SHOWMAXIMIZED);<br />
m_pMainWnd->UpdateWindow();<br />
It is maximizing the program correctly. My problem is that when it loads, it is not the active program. Any help on how to fix this is appreciated.

Thanks a lot. Not exactly what I was looking for but the answer wasn't far off. I just needed to add the line:
<br />
m_pMainWnd->SetForegroundWindow();<br />
Later.

Hello, can anyone tell me how to minimize a dialog box programatically to
the system tray on start up. Like MSN messanger or ICQ.
Thank You
