Is there anything in the OnInitDialog() method?
The only "odd" thing I see is this:
CSurchrgDlg::CSurchrgDlg(CWnd* pParent )
: CDialog(CSurchrgDlg::IDD, pParent),
m_theApp (* static_cast (AfxGetApp())) Try removing the initialization of m_theApp and see what that does.
What is m_vecBuffer?

thanks for you reply, I could remove the m_theApp and the app would still crash on the same spot.
the m_vecBuffer is defined like this :
std::vector<receiverec> m_vecBuffer;
in dlg.cpp const std::vector<receivebin>::size_type BUFFER_SIZE = 10000;
BOOL CSurchrgDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// Add "About..." menu item to system menu.
// IDM_ABOUTBOX must be in the system command range.
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);
}
}
// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon
// TODO: Add extra initialization here
CWinApp& theApp = (* (static_cast<cwinapp*> (AfxGetApp())));
m_bCanceled = false;
m_strCycle = "";
//PostMessage( WM_COMMAND, IDC_OK );
m_pThread = AfxBeginThread((AFX_THREADPROC)Run, (LPVOID)this, THREAD_PRIORITY_NORMAL, 0);
return TRUE; // return TRUE unless you set the focus to a control
}
void CSurchrgDlg::OnSysCommand(UINT nID, LPARAM lParam)
{
if ((nID & 0xFFF0) == IDM_ABOUTBOX)
{
CAboutDlg dlgAbout;
dlgAbout.DoModal();
}
else
{
CDialog::OnSysCommand(nID, lParam);
}
}

Comment this out and see what happens.
Does the application crash when it starts or when it is exits?

hi, David
If I comment the m_pThread out it will hang forever and with no message show on the dialog.
this app crash when it exits, but if I run another simular app, the dlg from
BOOL CXXXXXDlg::InitInstance()
{
CXXXXXDlg dlg;
would already have the value like {CXXXXXDlghWnd=0x00e90000}, but this one will have {CSurchrgDlghWnd=0xCCCCCCCC} instead, so I think it's because it didn't initialize right, looks like the dlg info is from CDialog, CWnd, but I couldn't find out where exactly it's calling CDialog and getting the info

With the breakpoint on the CSurchrgDlghWnd dlg; statement, CSurchrgDlghWnd.hWnd will likely have a value of 0xcccccccc. This is fine. With the breakpoint on the dlg.DoModal(); statement, CSurchrgDlghWnd.hWnd will likely have a value of 0x00000000. This is fine.
The problem at this point is that the secondary thread you are creating is still active when the application is exiting. What does this thread do? Does it communicate with the main thread or any UI component?

Thanks for following up
if I set breakpoint at dlg.DoModal();
{
CSurchrgDlg dlg;
m_pMainWnd = &dlg;
dlg.DoModal();
}
I will still have &dlg with value 0x0000000, dlg 0x0000000 and m_pMainWnd 0x0000000, that's why I keep thinking it's broken at the beginning
I will look more about the secondary thread. thanks!

If you don't mind me looking at your code (no proprietary or copyright issues), I would suggest packaging it up into a .zip file and e-mailing it to me and I'll take a look at it. Make sure to include the whole project so that I can just open the .dsw file, compile it, and see the problem.

You have to Enable WinSocket support in your project/application to make you project network enabled

All programs, at least the ones I use and have used in the past, can be used in a network environment. I do not know of a reason that someone would purposely code something like:
if (is_machine_on_network() == true)
exit();Other than that, you'll have to be more specific with your question(s).

Please Sir, My problem is like this :
I am using Sql server 2000 as database.
If I make my program without complicate settings, this .exe file can be used by everybody from a network ? And can it work well or Not ?

yeah, but database service should be done in server and other client should just GET/PUT data on server and data connection must be mainatined by Server..
