I don't know. But as I said before, GetLength is a member function of the CString object, so *one* of us is going to have to look in the documentation for CString.

(Or just type it in, and let the compiler tell us. I'm lazy enough to do that!)

You can use the CRT built in support to track memory leaks. Use the api - _CrtDumpMemoryLeaks(). Check this for how to use it - http://weseetips.com/2008/06/17/how-to-detect-memory-leaks-by-using-crt/[^]

Another good article about detecting and isolating memory leaks. Seems good one - http://software.myjoin.cn/article/article0006.htm[^]

how to make messenger styple popup in bottom right corner

garyofcourse3-Jul-08 0:07

Hi, Im programming in visualC++ with MFC in vs2008.

When using some applications like instant messenger, whenver someone signs in there is a popup in the bottom right corner of the screen saying 'xyz has signed in'. I want to make a popup like that. It should rise up from the status bar and then drop back down into it the way it happens in messenger. In addition the rest of the program should not stop running when that popup is rising up and lowering down.

Except I have no idea how to do this.. Can anyone offer some tips, name some APIs or link me to some articles on this? Im not exactly sure what this topic is called so I cant even do a decent search on it.

Thanks for any help.

You can use CMFCDesktopAlertWnd[^] if you are using MFC feature pack.

Else you need to create a top most popup window most probably a captionless dialog will do and then use AnimateWindow to make the window slide/fade in.

Also you've got to make the window appear alongside the window's taskbar so take note of the taskbar position too.

when i look into 7z's code,
find this:

namespace NSignature
{
  UInt32 kLocalFileHeader   = 0x04034B50 + 1;
  UInt32 kDataDescriptor    = 0x08074B50 + 1;
  UInt32 kCentralFileHeader = 0x02014B50 + 1;
  UInt32 kEndOfCentralDir   = 0x06054B50 + 1;
  UInt32 kZip64EndOfCentralDir   = 0x06064B50 + 1;
  UInt32 kZip64EndOfCentralDirLocator   = 0x07064B50 + 1;
  
  class CMarkersInitializer
  {
  public:
    CMarkersInitializer() 
    { 
      kLocalFileHeader--; 
      kDataDescriptor--;
      kCentralFileHeader--;

      kZip64EndOfCentralDir--;
      kZip64EndOfCentralDirLocator--;
    }
  };
  static CMarkersInitializer g_MarkerInitializer;

UAC in Vista

Hi,

I read that if Vista sees an external manifest file if will enable prompt. That's why we have to embed manifest file in the exe to enable application for UAC. Is it right? If any one knows that link can u send me that link.
I am trying to find that link for couple of hours but i am not able to find it now.

Thanks

How to Clear IE history under a limited account of VISTA

moye25012-Jul-08 22:26

moye2501

2-Jul-08 22:26

The code works under XP, both administrator or limited account.
But when I run it under Vista, it works under a administrator account, but doesn't work under limited account.
Sometimes, the history is cleared at first, but it appears again when I restart IE.

The code is shown as follow:

USES_CONVERSION;
CoInitialize(NULL);

TCHAR szSpecialFolderPath[MAX_PATH];
::SHGetSpecialFolderPath(::GetDesktopWindow(), szSpecialFolderPath, CSIDL_HISTORY, FALSE);

IUrlHistoryStg2* pUrlHistoryStg2 = NULL;
HRESULT hr = CoCreateInstance(CLSID_CUrlHistory, NULL, CLSCTX_ALL, IID_IUrlHistoryStg2, (void**)&pUrlHistoryStg2);
if(SUCCEEDED(hr))
{
    hr = pUrlHistoryStg2->ClearHistory();
    pUrlHistoryStg2->Release();
    CoUninitialize();
    return TRUE;
}
else
{
    CoUninitialize();
    return FALSE;
}

Thanks a lot!

With AfxBeginThread, it is __cdecl,
with CreateThread, it is __stdcall.

Is there an safe API wait to create a thread in MFC?
CreateThread?
I'd like to the easier one, if there is.
