So the new object can then call it. Keep getting errors along the lines of: error C2664: '__thiscall CTest::CTest(void (__cdecl *)(char *))' : cannot convert parameter 1 from 'void (char *)' to 'void (__cdecl *)(char *)' Can Anyone offer Any Advice, it work if i declare the function as a static. Guess it's a c++/c isssue. The function prototype is for a standard c function where i want it to be for a class memeber function Or is this the sort of thing that should be done through some Object Orientated Programming principle. Thanks, Much Appreciated Richard Jackson Re: Passing Pointers To Function In C++ Tim Deveaux20-Oct-01 5:04 Tim Deveaux 20-Oct-01 5:04  Yes, you've pretty much got it - the non-obvious part is the passing of the implicit this pointer to member functions, which alters the function signature of those functions. Filter on thiscall in this forum for more info. There's also a bit in the FAQ on using member fns as C (Windows) callbacks. *** Multiple Client Socket in MFC *** Salman Ahmad Khan20-Oct-01 0:24 Salman Ahmad Khan 20-Oct-01 0:24  Hi, in MFC using CSocket or CAsyncSocket following approach can set communication between a client socket and a Connecting socket on server side. ListeningSocket.Accept ( ConnectingSocket ); Problem, How will multiple clients be implemented? I have the clue that Link List, Array, Threads might be used for creating multiple connections with multiple clients. like ListenSock.Accept ( ConnectSock[i] ); BUT how will the messages be handeled. How will one connecting socket differentiate form otherones message. PLZ HELP !!!!! RawCoder Re: *** Multiple Client Socket in MFC *** NormDroid20-Oct-01 0:35 NormDroid 20-Oct-01 0:35  I would strongly recommend NOT using the MFC implementation wrappers for sockets. The best and *orthodox* way to to use raw sockets WSAEvent etc. A very good book to but describing the programming of sockets for windows is "Winsock 2.0" - By Lewis Napper. Re: *** Multiple Client Socket in MFC *** Salman Ahmad Khan20-Oct-01 1:10 Salman Ahmad Khan 20-Oct-01 1:10  I really need to do it in MFC due to time constraint. RawCoder Re:First, learn TCP/IP! Masaaki Onishi20-Oct-01 11:51 Masaaki Onishi 20-Oct-01 11:51  Hello, the codegurus around the world. First, you had better understand the concept of TCP/IP. Server idnetifies the client with IP address and the port number. This means that the client machine is assigned to the different IP address, so server can understand the different client with IP address. So, you may need the other code to restore IP addresses with the current access to the server, and differntiate the incoming socket with IP address. (I think that this works, but I never implement this level of code. ) Have a nice day! -Masaaki Onishi- Re: *** Multiple Client Socket in MFC *** 20-Oct-01 12:38 20-Oct-01 12:38  as far as i know, what can be done is for each client spawn a thread and all the window messages will be handled in that thread. so by this way multiple clients can be done. Sure u can do this using MFC. u can get a lot of source code in internet. may be have a look at www.naughter.com For learning c++, which one will be you choice? flying20-Oct-01 0:05 flying 20-Oct-01 0:05  "The C++ Programming Language" or "C++ Primer" and why? Re: For learning c++, which one will be you choice? NormDroid20-Oct-01 0:37 NormDroid 20-Oct-01 0:37  Both, The primer is elegant in its simplicity describing C++, after you got over the learning curve, "The C++ programming languauge" become your bible, and is much more detailed. Looking support for c++ in Linux Gaurav Lambole20-Oct-01 0:01 Gaurav Lambole 20-Oct-01 0:01  is there any support for c++ in Linux, I just want to develop some word pad kind of stuff in c++ for Linux..... can you give me any info about it.... Gaurav Lambole webdunia.com (India) pvt.ltd. Re: Looking support for c++ in Linux markkuk21-Oct-01 19:47 markkuk 21-Oct-01 19:47  Yes, gcc (Gnu Compiler Collection) contains a very good implementation of C++. It is included in all complete Linux distributions, but it might not be installed by default. There are also various GUI front ends to the compiler, e.g. KDevelop. How to destroy Array of Controls 19-Oct-01 21:24 19-Oct-01 21:24  I have to give a data tip on every record(each recod contains three points) on mygraph.For this i am creating Button controls for every point in for loop as like MyFuntion(){ for(firstrecord,somerecords(nearly25),lastrecord) { CButton *pCon=new CButton;//start point CButton *pCon1=new CButton;//peak point CButton *pCon2=new CButton;//end point pCon.Create(_TEXT(""),WS_VISIBLE|BS_FLAT,CRect,this,Number) pCon1.Create(_TEXT(""),WS_VISIBLE|BS_FLAT,CRect,this,Number) pCon2.Create(_TEXT(""),WS_VISIBLE|BS_FLAT,CRect,this,Number) m_datatip.AddTip(Text,pCon,Number); m_datatip.AddTip(Text,pCon1,Number); m_datatip.AddTip(Text,pCon2,Number); } } I am calling this function from OnPaint. For very first this code is working exactly.When ever i am calling this function next time the controls not destroying. I used "delete [] control" ,"delete control" in various places in my function and i didn't get the solution. Please help me , Where can I delete these created controls for callling the Myfunction next time. Re: How to destroy Array of Controls NormDroid19-Oct-01 23:48 NormDroid 19-Oct-01 23:48  In your header... typedef CList<cbutton*, cbutton*=""> ButtonList; class CYourDialog or CWindow..... { ButtonList m_listButtons; } and when you create the buttons in your cpp implementation file... m_listButtons.AddTail(pCon1) m_listButtons.AddTail(pCon2) ... etc and when your ready to delete the buttons, preferrable as the window/dialog is closing.. while (!m_listButtons.IsEmpty()) delete m_listButtons.RemoveTail(); Normski - Windows Professional Programmer Re: How to destroy Array of Controls 21-Oct-01 19:10 21-Oct-01 19:10  Thank you for your Information. I used this code in my project ,but i didn't detroy all my created buttons. I am using like this... MyFunction() { CButton *pCon; for(int i=0;i<15;i++) { pCon=new CButton; pCon->create(_TEXT(""),WS_VISIBLE,CRect(),this,i); m_buttonlist.AddTail(pCon); } // //my remaining code // while(!m_buttonlist.ISEmpty()) { m_buttonlist.RemoveTail(); pCon->DestroyWindow(); } In the above attempt the last created button only destroyed. How can destroy all the created buttons in the for loop; please help me. anju Re: How to destroy Array of Controls 21-Oct-01 19:58 21-Oct-01 19:58  >while(!m_buttonlist.ISEmpty()) >{ >m_buttonlist.RemoveTail(); >pCon->DestroyWindow(); >} You forgot to get the pointer to the button when you removed the tail. while(!m_buttonlist.ISEmpty()) { pCon = m_buttonlist.RemoveTail(); pCon->DestroyWindow(); } Re: How to destroy Array of Controls 22-Oct-01 8:30 22-Oct-01 8:30  ARRRRRAGGGGHHHHHHH!!!!!!!! DELETE!!!!!!!!!!!!! while(!m_buttonlist.IsEmpty()) { pCon = m_buttonlist.RemoveTail(); pCon->DestroyWindow(); delete pCon; //always delete when creating with 'new' } Re:Thanks 24-Oct-01 20:18 24-Oct-01 20:18  thank u sir, Now the code workig exactly what i need, once again thank you sir. HOW TO CHANGE THE IP ADDRESS?? Daniel Visan19-Oct-01 21:17 Daniel Visan 19-Oct-01 21:17  Hi, codegurus from worldwide. I want to change my IP address and it seems nobody can help me. But i'm tring again now asking all of you. It is about static IP on any WIN95/98/NT platforms. I know IPCONFIG on NT and WINIPCFG on WIN95/98 is able to do that using inetmib1.dll. So that i've tried to do my job using inetmib1.dll and i managed to do everything but changing those read-write MIBII attributes, including IP address. For solving my problem, I promise 1000x for that guru of all codegurus in the world and i'll be his fan forever. Accept my apologize for not such a good English. _DEBUG macro parag19-Oct-01 20:04 parag 19-Oct-01 20:04  Hi i see this code in most of the downloaded examples but what does this code really do ?

One of them is active at any given time. When I resize the window, the currently active view behaves fine, but when I switch to one of the others, they keep the size they were before. So how can I size my view to be as big as the client area of the frame window it is in. LP CTreeCtrl Question Vu Nguyen19-Oct-01 14:47 Vu Nguyen 19-Oct-01 14:47  Hi all!
