Re: Mulitple SDI windows. Vuvirt24-Jan-02 4:52 Vuvirt 24-Jan-02 4:52  Hello, I've got a very simple decision to your problem Here it is: void CYourView::OnFileNew() { WinExec(AfxGetAppName(),SW_SHOWNORMAL); } Add a handler of ID_FILENEW menu from the classwizard in your CView derived class with the above code. Enjoy! Best regards, X3m Re: Mulitple SDI windows. Jon Newman24-Jan-02 5:07 Jon Newman 24-Jan-02 5:07  now the app keeps re-opening itself and required the PC to be turned off. Is there a way of just re-initialising the main window each time and not the app? .NET or not .NET? MFC is the question...... Re: Mulitple SDI windows. Vuvirt25-Jan-02 2:32 Vuvirt 25-Jan-02 2:32  Are you sure you handle OnFileNew in your CView and not in your CMainFrame or CWinApp class? I have a working code of this if ou wan't I can email it to you? Best regards, X3m Re: Mulitple SDI windows. Jon Newman25-Jan-02 6:43 Jon Newman 25-Jan-02 6:43  yes if you would do so that would be great. jonathann4@hotmail.com .NET or not .NET? MFC is the question...... Re: Mulitple SDI windows. Vuvirt28-Jan-02 21:58 Vuvirt 28-Jan-02 21:58  I sent it to your email. Best regards, X3m timer Jerome Conus24-Jan-02 1:23 Jerome Conus 24-Jan-02 1:23  Hi ! I need to check in a C++ app, as precisely as possible, the time spent by the processor in a function. I have no idea where to start ! Any help will be greatly appreciated ! Jerome Re: timer Joaquín M López Muñoz24-Jan-02 2:51 Joaquín M López Muñoz 24-Jan-02 2:51  If you have access to the source code of the program, and the version of your Visual Studio installation is Professional or Enterprise, then you can do a profiling of your code, which gives you more or less accurate summaries of the time spent by the program in each function. You can start learning about profiling in Visual Studio with Cornell University tutorial Profiling with MS Visual Studio Tools.

Here's a simple class, it's not my idea, unfortunately I don't know whose copyright it is, I think it's from somwhere at CP: #pragma once class CDuration { protected: LARGE_INTEGER m_liStart; LARGE_INTEGER m_liStop; LONGLONG m_llFrequency; LONGLONG m_llCorrection; public: CDuration(void); void Start(void); void Stop(void); long GetDuration(void) const; }; inline CDuration::CDuration(void) { LARGE_INTEGER liFrequency; QueryPerformanceFrequency(&liFrequency); m_llFrequency = liFrequency.QuadPart; // Calibration Start(); Stop(); m_llCorrection = m_liStop.QuadPart-m_liStart.QuadPart; } inline void CDuration::Start(void) { // Ensure we will not be interrupted by any other thread for a while Sleep(0); QueryPerformanceCounter(&m_liStart);} inline void CDuration::Stop(void) {QueryPerformanceCounter(&m_liStop);} inline long CDuration::GetDuration(void) const { return (long)(m_liStop.QuadPart-m_liStart.QuadPart-m_llCorrection)*1000000.0 / m_llFrequency;} usage e.g.: CDuration durat; durat.Start(); FunctionCallToMeasure(); durat.Stop(); long ms_needed = durat.GetDuration(); I think the GetDuration return gives the time in milliseconds. I try to find the docu, then I can tell you more! Good Luck, Flo Re: timer Jerome Conus24-Jan-02 4:19 Jerome Conus 24-Jan-02 4:19  Thank you a lot for your help !

I'm working on a real-time App, which controls a machine, but we're having problems reaching the required speed of the machine. Thus, I wanted to check where, in the software, we are loosing time ! It's not easy !!!

GetModuleFileName returns the complete path of the specified module, so to obtain the path without the name of the module you should do something like: char strPath[_MAX_PATH]; GetModuleFileName(NULL,path,sizeof(path)/sizeof(path[0])); char *pSlash=strrchr(path,'\\'); if(pSlash)pSlash[1]='\0'; This gives you the path for the .EXE that loaded your DLL. If what you want is the path of the DLL itself, then replace GetModuleFileName(NULL,...) with GetModuleFileName(hInstance,...), where hInstance is the hInstance passed to your DllMain entry point. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Child windows inside a class (W32, not MFC) 23-Jan-02 21:38 23-Jan-02 21:38  I am trying to create a child window inside a class. I have the hwnd and hinstance to the main window available to the class. The problem that I am having is that the class needs to handle the WNDPROC for the window. I figure that MFC does something like this, but seeing that we cant view the complete MFC source code, I can't see how it is done there. Anyone have any input? Re: Child windows inside a class (W32, not MFC) Michael P Butler23-Jan-02 22:15 Michael P Butler 23-Jan-02 22:15  From Paul Dilascia's Windows ++ ////// // Now "hook" the window's window proc--i.e., subclass it, saving // the original window procedure. // oldProc = (WNDPROC)GetWindowLong(hwnd, GWL_WNDPROC); SetWindowLong(hwnd, GWL_WNDPROC, (LONG)theApp->getWndProc()); The book is well worth reading if you are attempting to create your own Windows class framework.

I don´t know if that would work, but IIS includes some COM thing called DONTS, and are some COM objects that let you for exmaple send one e-mail using VBScript and ASP, so if it is going to be in the server side maybe you can use that...
