LeonOrient Is it possible to create a world inside C++? keeper_sakeris2-Jun-03 16:26 keeper_sakeris 2-Jun-03 16:26  I want to know if you could create a real life world inside C++? Because I have had a really crazy idea.. now I know it may seem really stupid but think about the possiblities if you could do it. That is why I am trying to find some people to help me in the creation of a world that you would be able to enter through VR. Yes, if you are asking it is sort of like the matrix. However, you will be able to access it through a VR helmet or something of that nature however, that is beside the point. Firstly, I just want to know if it is possible. So please help me.

"Real life" is always (*always*) != "Simulations of RL" and will *always* be no matter how 'sophisticated' they are made. b. Computers can only (*only*) handle simulations and that's always TRUE to all time. Therefore what you are asking is impossible. Regards, Michael Mogensen, mm it-consult dk.

Re: Is it possible to create a world inside C++? Michael Andrew3-Jun-03 0:53 Michael Andrew 3-Jun-03 0:53  I suggest that VRML might be a start. You can write your worlds as text files, which gets processed by a VRML engine to create the world that could be viewed through a VR helmet or just on screen. Elaborate and interactive worlds can be created without using any C++ programming. Scripts can also be run enabling the author to create movement of objects within the world independant of the viewer. I would suggest doing a search for some VRML worlds on the internet. In programming terms, the ParallelGraphics VRML Cortona engine has some neat COM interfaces which allows the inclusion of 3D worlds in your own programs and 3d interaction ( see www.parallegraphics.com) Processing speed is a real problem though. The more real the simulation, the bigger the volume of data to process which takes longer and longer to update. Currently, PCs do not have enough grunt to produce a real real world. To produce realistic animated faces etc as well all the usual viewer parallelaxes etc will kill most PCs for a long time in the future (but I would like to be wrong). Using VRML, you can only produce simple dynamic and interactive worlds. Most authors use it model sophisticated shapes rather than whole worlds. If you want something more complicated, I guess that you would have to resort to using the imagination, as we currently do.

I understand that most pc's today are just to slow to handle such a request I just wondered if it were possible to do such a thing.. at this point in time... Till then... "Life is a game that can't be won..." Re: Is it possible to create a world inside C++? basementman9-Jun-03 6:36 basementman 9-Jun-03 6:36  You may be better off looking a the game Wolfenstein 3D. This type of approach, where you preconstruct the images at startup may be a better starting point and more practical, given today's processing speeds. I think that if you could pull it off, it would be COOL. About MFC SetFocus() jcpooh2-Jun-03 16:20 jcpooh 2-Jun-03 16:20  Hi all, I'm trying to make the child window (in C123 class) pop-up with focus on a Edit text box (m_CName). Then I write : //in parent class function //CString m_SName; //CEdit m_CName; C123 abc; abc.m_SName = "john"; abc.m_CName.SetFocus(); abc.DoModal(); //RESULT only display the name "john" in the edit box, without set the focus on this field. What's wrong? Thx Joli Re: About MFC SetFocus() valikac2-Jun-03 18:05 valikac 2-Jun-03 18:05  One solution is to override OnInitDialog() and call SetFocus() on the editbox inside it. Kuphryn Re: About MFC SetFocus() jcpooh2-Jun-03 19:29 jcpooh 2-Jun-03 19:29  Does it mean to override the OnInitDialog of the child C123? If yes, I wrote: BOOL C123::OnInitDialog() { m_CName.SetFocus(); CDialog::OnInitDialog(); return TRUE; } but there is no change. ?? Re: About MFC SetFocus() valikac2-Jun-03 20:13 valikac 2-Jun-03 20:13  Post a message vis PostMessage(). Post WM_SETFOCUS. Kuphryn Re: About MFC SetFocus() jcpooh2-Jun-03 20:36 jcpooh 2-Jun-03 20:36  I have used : m_CName.PostMessage(WM_SETFOCUS); // and delete the CDialog::OnInitDialog in C123::OnInitDialog but still not work Re: About MFC SetFocus() Michael Dunn2-Jun-03 20:31 Michael Dunn 2-Jun-03 20:31  You can't call SetFocus() until the dialog is created. The way you have it now, you're calling a method of m_CName before the control exists. THe proper way to set focus to a control is in OnInitDialog() and return FALSE from OnInitDialog() --Mike-- Latest blog entry: *drool* (Alyson) [May 10] Ericahist | Homepage | RightClick-Encrypt | 1ClickPicGrabber "You have Erica on the brain" - Jon Sagara to me Re: About MFC SetFocus() Anonymous2-Jun-03 20:38 Anonymous 2-Jun-03 20:38  I stand to be corrected but in OnInitdialog looks good to me but should you not return FALSE when specificaly setting the focus. You are returning TRUE which If my memory serves me correctly is wrong. The default implimentation adds a comment stating this. Hope it was of some help cheers Re: About MFC SetFocus() Anonymous2-Jun-03 20:40 Anonymous 2-Jun-03 20:40  Sorry, I see "Michael Dunn" has already said this, I did not see his response at the time. cheers Re: About MFC SetFocus() jcpooh2-Jun-03 20:56 jcpooh 2-Jun-03 20:56  I got it Thx all. OCX tweak el davo2-Jun-03 15:08 el davo 2-Jun-03 15:08  Say that you have created a new dialog based project, and included some OCX as an object in that dialog. Is there any way to override the OCX's OnPaint()? Thanks, David typename keyword question Joe Woodbury2-Jun-03 14:43 Joe Woodbury 2-Jun-03 14:43  VC++ .NET 2003 supports the typename keyword. However, by all appearances this keyword is superfluous. The compiler "knows" whether a reference object is a type (else my code in question wouldn't have compiled with the previous compiler.) So can anyone, in plain english explain why typename really is needed (aside from making the compiler ISO compatible)? Re: typename keyword question Joaquín M López Muñoz2-Jun-03 20:51 Joaquín M López Muñoz 2-Jun-03 20:51  Supposedly, it helps the compiler spot errors before instantiation time. Follow this link[^] for a particularly pathological example (I guess all examples with regard to this subject are pathological anyway).
