new and VirtualAlloc George_George12-Jan-08 21:42 George_George 12-Jan-08 21:42  Hello everyone, I heard some points that the memory allocated by new does not belongs to virtual memory, and onlymemory allocated by VirtualAlloc belongs to virtual memory. 1. I think this statement is not correct. Since all memory touched by current process belongs to virtual memory (either reserved or committed). No matter how (through which API) developer is using. 2. And new always utilize VirtualAlloc in underlying internal implementation code, so new (in implementation point of view) will consume virtual memory -- the same as what VirtualAlloc does. Are my points (1) and (2) correct? thanks in advance, George Re: new and VirtualAlloc CPallini13-Jan-08 1:39 CPallini 13-Jan-08 1:39  All of the application's memory belongs to virtual one. If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile. [my articles] Re: new and VirtualAlloc George_George13-Jan-08 2:39 George_George 13-Jan-08 2:39  Thanks CPallini, 1. So, I think you mean the memory either allocated by new or allocated by VirtualAlloc should be counted as part of the virtual memory in the Perfmon virtual bytes counter, right? 2. I think new is always implemented through HeapAlloc, and do you think HeapAlloc is implemented using VirtualAlloc? 3. If so, then new is implemented through VirtualAlloc? regards, George Re: new and VirtualAlloc zengkun10013-Jan-08 4:20 zengkun100 13-Jan-08 4:20  Delve into the Microsoft VC++ runtime library, you'll find that new operator is implemented in terms of VirtualAlloc .

So, both the memory allocated by new and VirtualAlloc should be counted as a part of virtual memory counter of Perfmon, right? regards, George Re: new and VirtualAlloc zengkun10013-Jan-08 23:19 zengkun100 13-Jan-08 23:19  In fact, you should treate every piece of memory used in your process as virtual memory. Windows manages memory allocate and deallocate, and where does the memory really exist is transparent to you. A Chinese VC++ programmer Re: new and VirtualAlloc George_George13-Jan-08 23:20 George_George 13-Jan-08 23:20  Thanks zengkun100, My question is answered. regards, George Re: new and VirtualAlloc 22491713-Jan-08 21:55 224917 13-Jan-08 21:55  Each porcess has a default heap, new operator uses heap functions that internally manages virtual memory for you. However you are free to create additional number of heaps for your process. Where as virtual memory functions directly allocates memory in terms of pages. There are more parts to the windows memory subsystem like Global memory and local memory also.

Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search. However, the file is opened successfully. If the app is started ahead before I double click a file, no such an error. modified on Sunday, January 13, 2008 2:54:16 AM Telnet, FTP and smtp server bigjoe11a12-Jan-08 17:04 bigjoe11a 12-Jan-08 17:04  I looking for source codes in VC++ Express that I can use to create a Telnet BBS (Server) FTP (Server) SMTP (Server) I just fount a lot of old stuff and was hoping there would be some thing newer from 2000 and above And PLEASE include the doc's for setting and compiling. Re: Telnet, FTP and smtp server Hamid_RT12-Jan-08 18:17 Hamid_RT 12-Jan-08 18:17  Did you search on the codeproject? Re: Telnet, FTP and smtp server bigjoe11a13-Jan-08 4:52 bigjoe11a 13-Jan-08 4:52  Yes, I have. The only code I can find is dated 1998 and older. This web site and forums section was my last hope. Thanks Joe Or maybe your not talking about searching on google.com. If thats the case. No. whats codeproject.

Re: Telnet, FTP and smtp server Hamid_RT13-Jan-08 5:16 Hamid_RT 13-Jan-08 5:16  Except Lounge forum that we have,its other world ont the codeproject. Re: Telnet, FTP and smtp server bigjoe11a13-Jan-08 21:53 bigjoe11a 13-Jan-08 21:53  I have been there and done that and still can't find what I'm looking for. thats why I posted this message. Re: Telnet, FTP and smtp server Hamid_RT13-Jan-08 5:14 Hamid_RT 13-Jan-08 5:14  So see FTP Visual C++ Examples[^] and in that[^] site you can see other things(HTTP,IMAP,,Upload,...) does it solve your problem?

Most of those are just samples for FTP uploads and things like that. Theres nothing there about FTP Servers or Telnet Servers or even SMTP servers One more thing your forums section doesn't seem to inform me of posts. So sorry I didn't know until I thought to check any way. Re: Telnet, FTP and smtp server Hamid_RT14-Jan-08 18:30 Hamid_RT 14-Jan-08 18:30  Does your problem solve? Re: Telnet, FTP and smtp server bigjoe11a15-Jan-08 8:14 bigjoe11a 15-Jan-08 8:14  No I'm sorry it's not. Most of the links that I have were not related to a Telnet, FTP and a SMTP servers. Just client applications and the ones I did find are more then 8 years old.
