CView is a class provided by the MFC Library. The MFC Library is provided to facilitate Windows Operating System Development for the C++ language. One should not be attempting to use such advanced libraries without having first achieved a minimal competence of using the C++ language and common tools such as compilers.

I want to display 3 different mouse cursors in CRichEditCtrl when mouse moves to different places respectively.

The 3 cursors are I-beam, arrow and hand.

I use SetClasslong(...) to change cursor, but, the function is not working.
The only cursor displayed is default (I-beam).

If yes, how?

the problem has been fixed by SetCursor(..) function other than SetClassLong(...).

Hi I am implementing security on Contact base smart card which follows scosta template.In card structure ef is directly under DF and DF is directly under MF. According to the template i am implementing security on elementary file(both sac and sae attributes are specified at time of creation in fcp) according to security condition read and update of record requires verification of pin(which is already defined in pin file).

Problem is that after implementing the security attributes on card now also my card is not following that,after selecting the file i can directly read and write on record, card does not ask for verification of pin.

please help me asap...............

The likeliness of getting a reply to your question is inversely proportional to the number of times you post it.

About your question - I'm sure if you google a bit you'll find something that points to some registry entries that will help you detect the language pack.

                     AfxGetInstanceHandle(),
                     WS_CHILD | WS_VISIBLE | MCIWNDF_NOPLAYBAR,

Have you tried MCIWndSetRepeat()?

In MSDN: "The MCIWndSetRepeat macro only affects playback that the user initiates by hitting the play button on the toolbar. It will not affect playback started with the MCIWndPlay macro."
In my application, user cannot see the toolbar beacause it is a background music. So the MCIWndSetRepeat didn't work. Frown | :(

Look at the MCI_DGV_PLAY_REPEAT flag available with MCI_PLAY.

Thanks. Does it mean I should use mciSendCommand() function instead of MCIWndPlay()?
I have tryed mciSendCommand(), but it seems cannot play same music at the same time, such as a gun fire after another (play gunFire.mp3 at 0:00, and anther at 0:03 without stop pre one). The MCIWndPlay() can handle this issue, this is the reason for that I prefer to use it.

Hello,

I have made a CMDIChildWnd derived window. but once maximized it cannot be restored . This is not Doc-View Architecture.

CMDIFrameWnd* pFrame = STATIC_DOWNCAST(CMDIFrameWnd,AfxGetApp()-
>m_pMainWnd);

if(!Create(NULL, FrameName,WS_VISIBLE | WS_CHILD |
WS_OVERLAPPEDWINDOW ,
CRect(0,0,200,200), pFrame, NULL))
{
TRACE0("Failed to create view window\n");
return false;
}

What must the problem ? Any ideas.

you may call ShowWindow(SW_RESTORE) to restore it.

when user clicks reatore-box (maximum-box), window receives WM_NCLBUTTONDOW.
you can use HitTest under the message to detect if restore-box is clicked.
