Hi,
i wrote the code as you told still its not
working,here is my code,please have a look
/////////////////////////////////////////////////////////////
BOOL CDlgApp::InitInstance()
{
AfxEnableControlContainer();
// Standard initialization
// If you are not using these features and wish to reduce
the size
// of your final executable, you should remove from the
following
// the specific initialization routines you do not need.
#ifdef _AFXDLL
Enable3dControls(); // Call this when using MFC in a
shared DLL
#else
Enable3dControlsStatic(); // Call this when linking to MFC
statically
#endif
if(NULL != ::CreateMutex(NULL, TRUE,_T("CSingleInstanceApp")))
{
long dwError = ::GetLastError();
if(dwError == ERROR_ALREADY_EXISTS)
EndDialog(NULL,IDOK);
}
CDlgDlg dlg;
m_pMainWnd = &dlg;
int nResponse = dlg.DoModal();
if (nResponse == IDOK)
{
// TODO: Place code here to handle when the dialog is
// dismissed with OK
}
else if (nResponse == IDCANCEL)
{
// TODO: Place code here to handle when the dialog is
// dismissed with Cancel
}
// Since the dialog has been closed, return FALSE so that
we exit the
// application, rather than start the application's
message pump.
return FALSE;
}
