Since you are using CDialog::DoModal, you should end the dialog with CDialog::OnClose.

HI Maxwell are you sure EndDialog() should not be used.
please refer msdn for CDialog::EndDialog and implementation of CDialog::OnOK().

You are right! It was my mistake.

the class instance gets released after EndDialog and the local dialog variable.
What about the resources used by the dialog class?
You may have written code to release it.
But are you sure the cleanup code gets executed?
Debug the code, if it hangs, debugger shows the waiting statement if you pause the running application in the debugger.
And you are doing some billpayment process, are handling connection to database correctly?

Do you allocated data with new or malloc ?
If so, Are you using delete or free to release the memory ?
Are you communicating (transmitting) data somewhere ? on the network, in a Database ? in a file ?
If you keep the data in memory, what happen when you add more and more data ? is it added in a "sorted" way ?
(in debug mode) When you just do a couple of "transations", and quit, does the debugger report memory leaks ?

I have few things to say.
Check if you have any Memory profiler tools nearby available to you.
Such as Rational purify or something else even one from codeproject.
Run your code once. That will fix your problem. You will definitely
get the location where u are going wrong.
Have patience. I know its too hard, but its the truth.

Post a message to the main thread and let it to do the stuff.

please clarify , what mwessage and param that i used in Postmemessage
|

Typically you do something like
#define WM_MY_CHANGE_CURSOR (WM_APP+1)
In a header file included both by your main thread source file and by the worker thread one.
Then, when appropriate (whenever you need to change the cursor), send the message from the worker thread to the main one, for instance
PostMessage(hWnd, WM_MY_CHANGE_CURSOR, wParam, lParam);
Where hWnd is the handle of the main window and wParam, lParam meanings are freely choosen by you (e.g. wParam maybe the index of the intended new cursor).
Finally, you properly handle the message (to do the graphics stuff) in the main thread, for instance using MFC ON_MESSAGE mechanism (see [^]).

Hallo everybody,
I am working on a MDI Application with 2 Child windows. What I want is:
1. the first child frame is always shown in MAXIMIZED mode.
2. the size of the second child frame is set to be smaller than MDI Main Frame.
My problem is, if I open the first child frame in MAXIMIZED mode and then open the second child frame in NORMAL mode, the first child frame will be automatically restored.
Can I prevent it?
Actually I need a popup window with such features: always top-Most in z-dimension, dynamically resizable. and the first child window in background will not be resored when the popup window is displayed.
Can I still use MDI-Child frame, or I have to create a frame window dynamically?
thanks a lot!
with best regards,
Li

i cant understand ur questiom MCIWnd is a funtion of mci which are use for multemedia.
|
|
|
|
|
My question was while creating the MCI window ( using the MCIWndCreate() ), which window did u specify as the parent...? Actaully u should specify the handle of the view class..
|
|
|
|
|
i m using this statement for MCIWndCreate.
where: CString m_Path;//for input file's path.
CAnimateCtrl m_Screen;//variable of Animation control.
HWND m_Video=MCIWndCreate(m_Screen.GetSafeHwnd(),AfxGetInstanceHandle(),
WS_CHILD| WS_VISIBLE|MCIWNDF_NOMENU| MCIWNDF_NOTIFYALL| MCIWNDF_NOPLAYBAR,m_Path);

Why r you using the CAnimateCtrl? more over a staement like CAnimateCtrl m_Screen will not create an animate control and because of that m_Screen.GetSafeHwnd() always returns 0. So instead of m_Screen.GetSafeHwnd(), pass the handle of the view class.
|
|
|
|
|
please tell me how can i get handle of view class.
here i m using a CFormView type of class.

From which class you are calling the MCIWndCreate() function. if it is from the Formview iteslf, you can get the handle using the GetSafeHandle() or simple use the m_hWnd variable( both this function and variable are members of CWnd and CFormView is indirectly derived from that class ). If you are creating the MCI wnd from some other class, get the view class pointer and the call GetSafeHandle() of that pointer.
