This eats ram like hell too:
CPen pen(PS_SOLID,1,m_clrForeground);<br />
CPen* oldpen=(CPen*)pDC->SelectObject(&pen);<br />
...<br />
pDC->SelectObject(oldpen);
I don't understand this, it's code I see a lot. I feel kinda stupid...
using: [VISUAL STUDIO 6.0 sp5] [WIN98/2]

Hi CPians!
I'd like to debug my app, which is a C-dll with visual C++ 6.0. It is bound to an application, which is loaded when starting the debugger.
My problem is that the debugger will not stop at the breakpoints ... I made sure that I have opened the corresponding file (I mean the file that actually gets compiled, and not a copy of the project), that my dll is really being loaded by the application (renaming it would crash the app), and that my code gets compiled (I do not get that message you usually get when trying to put a breakpoint on a part of code which is not compiled). Besides, I am really positive that the code has to go through where I put my breakpoints.
So ... I am lost ... any suggestion ?
Thanks

This can sometimes happen moved your project to a different directory, then editted code in the new directories. Some files are still pointing to the old directory.

Hi,
the MFC Dialog, sets the menu options in the OnInitDialog() method. look at the following code:
BOOL CMyDlg::OnInitDialog()
{
CDialog::OnInitDialog();
ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
ASSERT(IDM_ABOUTBOX < 0xF000);
CMenu* pSysMenu = GetSystemMenu(FALSE);
if (pSysMenu != NULL)
{
CString strAboutMenu;
strAboutMenu.LoadString(IDS_ABOUTBOX);
if (!strAboutMenu.IsEmpty())
{
pSysMenu->AppendMenu(MF_SEPARATOR);
pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
}
}
SetIcon(m_hIcon, TRUE);
SetIcon(m_hIcon, FALSE);
return TRUE;
}
the pointer pSysMenu is the handler to the system menu, and you can add your menu items using pSysMenu->AppendMenu() method, same as the MFC by default adds the 'About' menu.......
hope this helps ya

recently, i worked on printing program.
can anyone help me how to get the name of a system pre-defined paper?
such as :
value 1 return Letter (8.5 x 11 in.)
thanks

I think that may be a problem of the printer driver rather than the problem of the system.
I don't know it exactly, but the paper size is defined in the DEVMODE printer struct (member: dmPaperSize). But here the definiton is only per number (symbolic constant). So I think the printer driver does the mapping from those numbers to the string which is visible in the windows common printer dialog!
|
|
|
|
|
thank you CodeBrain,
I do know the member of DEVMODE dmPaperSize identitify the dimension of the paper. but not very easy to get the size in strings. maybe the only thing i can do is mapping constants to strings by myself.

Hi,
I have an existing Win32 console app. I want to now add user interface (MDI) to it, which obviously I would like to be run in a separate thread. I used AfxBeginThread to create a new MFC thread which creates my interface, etc. But, the problem is that in this implementation I do not have any CWinApp object at all, and therefore I cannot use some MFC functions. What is the correct way to create a user interface using MFC in a thread other than the main thread of my app?
Thanks,
Krishnan

Hi,
there are 2 types of threads in win32/mfc... applications:
1) worker thread.
2) UI thread.
your case is the second one, UI thread. all UI threads in MFC application must inherite CWinThread class..... then when you call AfxBeginThread(..) method, you pass your dervied-CWinThread object as the parameter.
the CWinThread class, has the method : "InitInstance()" there you must create the proper MDI objects you want to display.....
read about UI thread in the MSDN or here...
hope this helps ya
regards,
Yaron

I have already done that. But, the problem is how do I create a CWinApp object. Since, my app is a console app, I cannot declare a global variable for the CWinApp object. Also that object would be instantiated in the main thread, whereas my UI is in different thread.

I have installed SAPI5.1 on win2k machine. I also have L & H German language engine installed. I am trying to access the L&H voices programatically. However the ISPVoice Interface is unable to use L&H voices. I checked out the registry keys HKLM\\Microsoft\Speech\Voices\Token\ but didnt found any entry for L&H voice. Strangely enough when installed on another machine the entries were found along with extra files installed at C:\Program Files\Common Files\L&H\SpeechEngines\1031\TTS\TTS3000\
I tried installing installing the same downloads on different machine but in vain. None of them showed these required entries and these extra files...
Can anyone throw some light on this weird behavior????
