You've not provided enough info for a sufficient answer. A C program can only use C code, but a C++ program can use both C++ and C. Consider the following .CPP file: #include < iostream > #include < stdio.h > void main( void ) { printf("Hello World\n"); } Is it C or C++? Some folks would call it a C++ program because of the file's extension. Others would say not since it uses no C++ constructs. What if printf("Hello World\n"); were changed to std::cout << "Hello World\n";? Does that make a difference? In some instances, I think it can be a difficult question to answer. Re: C or C++? User 665823-Jul-03 12:12 User 6658 23-Jul-03 12:12  Ok, seems like I'm programming with a mixture of C and C++, I use classes and sometimes std::vector, which don't exist in C, but I also use strlen, fwrite etc, C-functions. Seems to be hard to tell whether a piece of code is pure C or already C++. Thank you all, you helped me understanding this topic regards modified 12-Sep-18 21:01pm. Re: C or C++?

If you look at the implementation some of those functions you'll be amazed that some are written in assembler! So would that make you an assembler programmer? What I think is: C++ is has OOP (Object Oriented Programming) support. If you would use it, you would be programming in C++. Then again, within those classes and member functions you use C code So what you shouldn't do is see C and C++ as 2 different languases, but see C++ as an extension to C !

How can I use a VB library, in VC++ mr200323-Jul-03 6:45 mr2003 23-Jul-03 6:45  Hi, I have a VB library file which has many functions/constants. How can I use that in a VC++ program? Should I make a VB dll file, and include all of the functions in it? Ehsan Behboudi Re: How can I use a VB library, in VC++ AlexO23-Jul-03 6:47 AlexO 23-Jul-03 6:47  You have to covert it to COM library. Re: How can I use a VB library, in VC++ mr200323-Jul-03 7:40 mr2003 23-Jul-03 7:40  how can I do that? Ehsan Behboudi Re: How can I use a VB library, in VC++ mr200323-Jul-03 8:23 mr2003 23-Jul-03 8:23  ok i just checked,, the library is written according to COM. what should i do next? Ehsan Behboudi Re: How can I use a VB library, in VC++ AlexO23-Jul-03 8:30 AlexO 23-Jul-03 8:30  use #import "myvbcode.dll" during c++ compilation it would generate myvbcode.tlh myvbcode.tli which are automatically included then just select the functionality you need. If you need more help, publish generated .tli file here and example of how you would use it in VB. Re: How can I use a VB library, in VC++ AlexO23-Jul-03 8:38 AlexO 23-Jul-03 8:38  P.S. #import "libid:12341234-1234-1234-1234-123412341234" where 12341234-1234-1234-1234-123412341234 is you LIBID, is preferable. This way you do not depend on the location of the COM dll during compilation. Re: How can I use a VB library, in VC++ mr200323-Jul-03 9:19 mr2003 23-Jul-03 9:19  where in the VC++ program should I add #import "myvbcode.dll" ?? Ehsan Behboudi Re: How can I use a VB library, in VC++ AlexO23-Jul-03 9:48 AlexO 23-Jul-03 9:48  Stdafx.h usually is a good place. In general, it should be treaded as any other include file - you put right before the code that uses it. the actual #import "myvbcode.dll" is substituted at compile time for #include "myvbcode.tlh" #include "myvbcode.tli" IWebBrowser2 from IE HWND Paul M Watt23-Jul-03 6:40 Paul M Watt 23-Jul-03 6:40  Hi all, I need to get the IWebBrowser2 interface from the HWND for an IE control. Currently I am using Active Accessibility to get the IHTMLDocument2 interface from an HWND. Normally you can get the IWebBrowser2 interface from IHTMLDocument2 by querying IHTMLDocument2 for the IServiceProvider interface, then calling QueryService to get the IWebBrowser2 interface. This does not appear to work going through active accessibility. I believe this problem may have something to do with the set of objects that are marshalled with active accessibility. If anyone has been able to successfully go from an HWND for an IE control to the IWebBrowser2 interface, I would really appreciate your help and solution.

All utils i've found until now who can do that, are with annoying company screens or with limitations (if you want to change this, get the professional edition .. arghhh) etc. Anyone found a very good one? or made one on its own? Let me know; Greetings Jens Re: setup maker AlexO23-Jul-03 6:46 AlexO 23-Jul-03 6:46  Do you mean that you do not want to pay for Wise or InstallShield and you are looking for freeware? There is free version of setup which comes with VS.Net , the problem is it does not have fancy UI and you really have to understand Installer SDK (available for free from Microsoft) Re: setup maker JensB23-Jul-03 6:51 JensB 23-Jul-03 6:51  Do you mean that you do not want to pay for Wise or InstallShield and you are looking for freeware? indeed, i have no desire to pay for a program who makes a setup. Don't need a fancy user interface, just the regular setup. Re: setup maker John M. Drescher23-Jul-03 7:11 John M.

Re: setup maker Toni7823-Jul-03 12:10 Toni78 23-Jul-03 12:10  I would go with John M. Drescher suggestion (InnoSetup), which is very simple to use. Also Windows has an installer and this is the website [^]. Also, check your Visual Studio CDs because it has InstallShield somewhere, and there is also a tutorial on how to use it here in CodeProject. // Afterall, I realized that even my comment lines have bugs When one cannot invent, one must at least improve (in bed).-My latest fortune cookie Re: setup maker JensB23-Jul-03 21:43 JensB 23-Jul-03 21:43  first of all .. thank you guys for the fast reply I worked with the InnoSetup program. The program was exactly what i was searching for. Nice done! Greetings Jens Re: setup maker (PROBLEM) JensB23-Jul-03 23:37 JensB 23-Jul-03 23:37  hey guys, i've seem to have one problem with 'InnoSetup'. I've added to script that install has to make a desktop shortcut. After install, i open the shortcut. The program launches. But then i get an error (error opening database file). 'Can not find c:\..\desktop\....db' file The program searches in the directory where the shortcut is made! It needs to search the database file in the same directory where the program executable really is (not where the shortcut is). The same happens when i open the shortcut on start-menu. It searches the database files where the start menu group is located at. The strange this is .. if i make a shortcut from my program to the desktop, i don't get this error and program is executed correctly. Anyone who can fix this problem? Greetings Jens stopping packets by hooking Kuniva23-Jul-03 6:31 Kuniva 23-Jul-03 6:31  I need to see the packets that pass my computer and filter out certain ones by ip address and port and data size, and then i have to stop them from arriving to the application they were meant for, how on earth can i do this???? There must be a way.. like hooking?? But i'm not sure.. All i ever hooked was the keyboard input so.. i'm not an expert on it. I just need to know if its possible, and how (like the hooking). Most firewalls can block a given ip or port so they must use some similar technique, anyone know what it is?
