Hello friends
I am facing the following simple problem (as I am very new to VC++). The purpose is to display second window/screen after the user clicks 'OK' in the first window/screen. But the problem is that the second window fails to get displayed. The code has been written as below...
Please help....
Thanks

BOOL CMyDialog::InitInstance()
{
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);

AfxEnableControlContainer();

#ifdef _AFXDLL
Enable3dControls();
#else
Enable3dControlsStatic();
#endif

CDialogfirstwindow dlg1;
m_pMainWnd = &dlg1;
int nResponse1 = dlg1.DoModal();
// The first window is successfully displayed
if (nResponse1 == IDOK)
{
//#if defined REQUIRED_CODE :
// This code has been introduced thinking that new window
// may need re-intialization..
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);

AfxEnableControlContainer();

#ifdef _AFXDLL
Enable3dControls();
#else
Enable3dControlsStatic();
#endif
// #endif
CDialogsecondwindow dlg2;
// The Second window fails to get displayed
m_pMainWnd = &dlg2;
int nResponse2 = dlg2.DoModal();
if (nResponse2 == IDOK)
{
}
else if (nResponse2 == IDCANCEL)
{
}
}
else if (nResponse1 == IDCANCEL)
{
}
return FALSE;
}

This has to do with m_pMainWnd and it's being assigned a NULL value. Read here for more.

Combining properties of Modal && modeless dialogs

Hello !
I need to have a dialog that will be used like a modal dialog box from an user point of view (so it means, the user can only interract with this dialog and no more with the program itself) BUT I need to work with it like a modeless dialog box from the code point of view (so it means that the program cannot be interrupted and must still run and print data in the underground window).

Is it possible to specify a modeless dialog to act like this ??
Thanks

Spawn the modal dialog in its own thread. i.e., in the mainframe, set up a thred function that calls dialog.domodal() and in the event handler that spawns the dialog, do AfxBeginThread(YourThreadProc, this); That should work.

Hi thank you for your response... and sorry for the delay (I had a very very long week-end Wink | ;)

).
The problem is that I need to send data to the dialog (a new data every 10 msec approximatively). The dialog will then print this data on screen. So, if my dialog is called with DoModal, I cannot send anymore data to it and that's a problem. And I cannot get the data from within the dialog, it must be sent to it.

Any idea ?

Thanks

i wonder, how MSN detects network connection, not internet but network connection, after that it tries to login user.

interesting fact is that i specified wrong DNS and gateway, but MSN detected local area network and tried to connect to its server.

so may be it use some system notifications? what do you think? really it can help me a lot.

thank your, Mike.

Bold font in CTreeCtrl truncates text

I have changed the font on some of my CTreeCtrl items.

The thing is that, when changing the font to for e.g. bold the text (in WinXP anyway) becomes to wide so the last letters are missing in the text-drawing region. Anyone have encountered the same problem?

You get a similar problem if your PC uses large fonts and you run the prog on a PC with small fonts. The PC with the smal fonts has the text truncated, usually aparent if static controls

Put
SendMessage(CCM_SETVERSION, 5);
in OnInitialUpdate();

There's more to it than that, but that will get you started.

display korean characters inside mfc dialog box

virtualweb9-Nov-04 20:11

virtualweb

9-Nov-04 20:11

Hello,

This question regards localization of an mfc application.

I create a base project from the MFC wizard in either Visual C++ 6.0 or .Net. On the 2nd page of the wizard I am asked what language I would like my resources to be in. I select Korean( For version 6.0 Korean must be added manually as it is not a default entry). I click Next to the remaining pages constructing a Multiple Document Interface (MDI).

I execute the application and see all the menu resources in Korean characters which is what I want. When I click on the About box of the sample application I have created, the dialog appears with ?? marks where the Korean characters should be displayed.

I understand in the resource editor of Visual C++ that it is limited to ascii characters and therefore I cannot view any of the korean characters from within the resource editor.

I am compiling the project with the default option of _MBCS ( Multi byte character set).
If I convert this preprocessor option to _UNICODE, the menus and the dialog resources are both displayed in korean. The problem is I need it to work with _MBCS.

I don't understand why the application when using _MBCS can display menus correctly (ie. in Korean characters) but displays dialog resources such as Text labels and buttons with question marks. It is as though it has only been half implemented.

I really need to be able to get the project to display using the _MBCS preprocessor as I will eventually need to display Korean characters in a large project and do not wish to convert it to unicode.(big job).

I have changed the font of the dialog to various fonts such as Gulim ( Korean supported font) also the virtual font 'Ms Shell Dlg 2'.

Thank you to everyone who can explaing to me what I am doing wrong or missing as to why a standard run of the mill MFC Wizard application only displays Korean characters in all the menu's but not in Dialog's or Frame resources.

Thank you very much

ok....tis a long story.....here goes......
u c.....the code.....

HICON hIcon = AfxGetApp()->LoadCursor( IDC_CURSOR1 );<br />
SetCursor( hIcon );<br />
return TRUE;

is a working code coz i have put this in my Dialog based application (Xyz) in a class called CXyzDlg..... that is, i have already added this function "OnSetCursor()".....and the cursor changes......in the main Dlg box but..... i have derived a class from the CStatic Class named it as "CMyClass".....and i have created obcts of it in the CXyzDlg class.....basically these objects i have created by placing the "static control" on the dialog box and then..... thru the class wizard created an object linking it with the picture control of type CMyClass(that is .....SUBCLASSING).....
also in thiz CMyClass i have added the "OnSetCursor()" function as well......and many other mouse functions like "OnMouseMove()","LbuttonDown()".....etc.....but here when i put in the same code as i had put in the main Dlg box for the "OnsetCursor()".....it does not change!!!!!......y??? Cry | :((

heres the code......that i have put in the derived class CMyClass......

I'm actually working with MFC for a long time..
But I've still been thinking I have so many things to study about MFC..

furthermore,, I wanna reorganize my MFC knowledge.
How can I restart again?

Which part of framework is the most significant in MFC do you think?
I've just digging into source code about MFC Message Map framework...

Is that good choice..
How can i make feel so satisfied about MFC, then can say I'm so perfect MFC programmer? Smile | :)

Thanks in advance...
