Sleep() 6-Mar-02 12:42 6-Mar-02 12:42  I'm trying to find out why the program doesn't sleep for 2 seconds after the first cout. #include <iostream.h> #include <windows.h> main() { cout << "blah\n"; Sleep(2000); cout << "blah\n"; return 0; } Re: Sleep() Serge Krynine6-Mar-02 12:49 Serge Krynine 6-Mar-02 12:49  Try this: main() { cout << "blah\n" << endl; Sleep(2000); cout << "blah\n"; return 0; } Re: Sleep() 6-Mar-02 13:36 6-Mar-02 13:36  Thanks, endl worked. I can't believe it was as simple as that and I couldn't figure it out. I didn't know that endl was different than \n.

It requires the header time.h #include iostream #include time.h using namespace std; clock_t wait // declares wait as clock_t, like declaring an int. void main() { wait = clock() + 2000; cout << "Blah\n"; if (wait <= clock() ) { Cout << "Blah"; } } Hope that helps. And it may not be all completly true, but im 99% sure it will work. Good Luck ~SilverShalkin Stay at the hights of the language for it will grow ever more, with non stop.

I want to parse a form so that I can read in the variables of the Name, Email and Message of my guestbook and then POST them. Re: HTML parsing Jon Sagara6-Mar-02 11:51 Jon Sagara 6-Mar-02 11:51  You're a sadist! I mean it's not impossible, and I'm sure there are already libraries that exist for this sort of thing, but I recommend using Perl, ASP, PHP, etc... These scripting languages have very convenient string maninuplation facilities built into them, and they integrate really well with existing web servers. Jon Sagara What about ?

Tx Michel If I am wrong or said something stupid, I apologize in advance MDI child windows Rajveer6-Mar-02 9:59 Rajveer 6-Mar-02 9:59  I've created an MDI application, and I'm doing graphics drawing in the child window using OpenGL. For some reason, whenever I draw something and then open a new window, the exact same scene is in the new window also. Also, if I have a few child windows open and I create or alter a scene in one of them, all other windows end up displaying the altered screen. This kind of defeats the purpose of an MDI application if every single child window is displaying the same thing. Why does this happen and how can I fix it? Re: MDI child windows Roger Allen7-Mar-02 5:23 Roger Allen 7-Mar-02 5:23  We had a similar problem in one of our OpenGL apps. Are you using call lists in the OpenGL rendering process? If you are make sure you are rendering to a unique call list number and playing back the correct one for the MDI window in question.

Virtual table and backward compatibility 6-Mar-02 9:25 6-Mar-02 9:25  I have DLL that hold pointer to class that allocated in other DLL, this class has virtual functions so the DLL can use it with no need to Export & Import this class. In these situation, I can add virtual functions to the class interface and the other DLL does no effected from it (backward compatibility...) in one condition: the new functions should be declared after the last original function, so the Virtual Table order is kept. so far so good, but here is my problem: this class is derived from base class that also has virtual functions, and if I want to add functionality to the base class the Virtual Table order is changed and I don't have backward compatibility. So, how can I add virtual function to base class without changing the virtual table order ??? Thanks in advance Didi Gurfinkel Re: Virtual table and backward compatibility Joaquín M López Muñoz6-Mar-02 9:36 Joaquín M López Muñoz 6-Mar-02 9:36  I'm not sure whether this will work, but it's simple to give it a try: derive virtually from your base class: class Derived: virtual public Base { ... }; Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Virtual table and backward compatibility 6-Mar-02 9:35 6-Mar-02 9:35  Wow, that was quick ! Its seemed that it works. Thanx DD Re: Virtual table and backward compatibility 6-Mar-02 9:50 6-Mar-02 9:50  Do you know what is the overhead of using virtual public ? DD Re: Virtual table and backward compatibility Joaquín M López Muñoz6-Mar-02 10:52 Joaquín M López Muñoz 6-Mar-02 10:52  Hmmm... I think it is about an extra pointer per virtual base class (with respect to space) and an extra offset when accessing data in a virtual base class (with respect to execution). But I'm far from 100% about this. Plus, implementations vary wildly between compilers, and I don't have much info about VC++ class layout.

Re: Standard Interfaces : MIDL Aaron Schaefer6-Mar-02 12:08 Aaron Schaefer 6-Mar-02 12:08  Yes. Also, make sure you have a COM_INTERFACE_ENTRY(IWhatever) in the COM_MAP in your CoClass's .h file. function pointer Steve Severance6-Mar-02 8:19 Steve Severance 6-Mar-02 8:19  Is it possible have a function pointer to a member function of a class? Thanks. Steve Not all who wander are lost... Re: function pointer [updated] Joaquín M López Muñoz6-Mar-02 8:34 Joaquín M López Muñoz 6-Mar-02 8:34  This is question #1 here at the forum. Please consult Mike Dunn's C++ FAQ.
