Re: return; in constructor??? patnsnaudy11-Oct-04 10:33 patnsnaudy 11-Oct-04 10:33  I guess that I meant when you new the object that a pointer to the object would be passed back. The one thing that I thought return in a ctor may do is pass back null and not create the object so: ctor a = new ctor(); // thought that it was possible that a would be null if ctor called return, but now I know that is not the case. I could have tested it, but didn't want to spend the time. Re: return; in constructor??? Michael P Butler11-Oct-04 5:07 Michael P Butler 11-Oct-04 5:07  All it will do is prevent the execution of code after the return statement. I consider it a bad practise, but I have seen developers use it whilst debugging.

This is a generic c++, rather a vc++ guestion, but i did not found another category to post it. Is well known that c++ is (general) slower that Fortran in numerical calculations. I benchmark my code and i found that the Fortran implementation is at least 3 times faster. The programm performs numerical calculation with floating point numbers, uses 3d or/and 4d arrays of doubles (actually arrays of pointers allocated dynamically with new operator). Sizes varies, but is typical the case 50x50x40x19 or greater. There are a lot of routines that uses 3 or/and 4 nested for-loops where manipulations within arrays are taking place. Searching the web i found that are existing a lot of array templates specially desinged for numerical computing purposes, but (as always) allmost no one is suitable for Microsoft's c++ compiler and Windows operating system. Is there any ideas about how i can boost the code? I have tried intel compiler but the difference is small... Thanks in advance for any ideas.... Re: Boost numerical calculations Nemanja Trifunovic11-Oct-04 3:08 Nemanja Trifunovic 11-Oct-04 3:08  Which version of VC++ are you using? VC++ 7.1 should be able to compile most of numeric template libraries (MTL, Boost uBlas, Blitz++). My programming blahblahblah blog. If you ever find anything useful here, please let me know to remove it. Re: Boost numerical calculations johnny__XP11-Oct-04 3:12 johnny__XP 11-Oct-04 3:12  Now i'm using Visual Studio 2002 .Net. I will move to 2003 .Net just to try Blitz++.... converting vector of pointeur to vector of pointeur to const Jerome Conus11-Oct-04 2:41 Jerome Conus 11-Oct-04 2:41  Hi ! I have a vector like : vector<myclass*> I need to return this vector as : vector<const myclass*> but I don't see any easy way to do it ! Do I really have to take each item of the original vector and add it to the target vector, converting it to const in the process ? Thanks for your help !

Re: how:notification when process is created gamitech11-Oct-04 3:08 gamitech 11-Oct-04 3:08  i think that you can do this with hooks in 2 ways. Either hook with CBT_PROC or you can hook the createprocess function and seee each time it's called. I f you work with drivers this will be very handy gabby Re: how:notification when process is created happycpp11-Oct-04 9:57 happycpp 11-Oct-04 9:57  can you tell me what API calls are needed to do it..

When it runs i want to suspend all other applications including mouse & keyboard. I know SetThreadPriority got something to do with this. But I dont know how to use it. Anyone can help me Re: Priority Arsalan Malik10-Oct-04 23:50 Arsalan Malik 10-Oct-04 23:50  By setting thread priority, you cannot stop mouse or keyboard. For mouse or keyboard, you have to disable interrupts  ARSALAN MALIK   Re: Priority Neville Franks11-Oct-04 0:15 Neville Franks 11-Oct-04 0:15  Please tell us all the name of your program so we know never to use it.

You might be able to do this by running all your code in a device driver (Ring 0). Note that I said might. There are non maskable interupts on PCs, and windows wasn't designed for drivers to mask interupts for very long. Odds are very good that you will see many unwanted side effects no matter how you work things. You need a real time OS, on hardware designed for this. Windows XP/NT is not. Windows CE is, maybe. Learn something about real time operating systems, and the problems they face. Decide which is for you. Until you understand this subject (which is very large) you cannot ask the right questions. Re: Priority Bob Stanneveld11-Oct-04 3:38 Bob Stanneveld 11-Oct-04 3:38  Why in the name of God do you want to stop the user from interaction with the computer? That would be the worst thing a developer can do... The way you get most CPU cicles is to set the priority to REALTIME. (more that a system process). Even that is not a wise thing to do. And the best and fastest way to get access to information on api's is to take a peek in MSDN[^]. Multiply it by infinity and take it beyond eternity and you'll still have no idea about what I'm talking about. fatal error C1189: #error : incorrect &lt;rpcndr.h&gt; version.
