Sonork - 100.10414 AcidHelm Big fan of Alyson Hannigan. VB and COM Mazdak26-Dec-01 8:17 Mazdak 26-Dec-01 8:17  I have general question about COM developing in VB. Does Visual Basic have something like ATL for COM developing(except ActiveX)?(I mean something like "simple object"in ATL) VB doesn't have pointers ,so How does it implement interfaces,methods and another things in COM. Are COMs that design in VB as strong as,as fast as or... COMs that in ATL have? Re: VB and COM Carlos Antollini26-Dec-01 8:36 Carlos Antollini 26-Dec-01 8:36  When you make a com object in something named VB, you not write the IDL. The interface is generated by the VB compiler... In same mode is easy to write com objects in VB, but the problem is that you don't have the control like in ATL projects when you write the IDL file... Best Regards... Carlos Antollini.

If you create a new project as an ActiveX DLL or ActiveX EXE, you will have COM servers, and all you need to do is to fill in the methods you want. Everything else is done by the compiler. However, COM servers created with VB depend on VB runtime, and they can never be lean and fast as ATL created.

Thanks, Kuphryn Re: Read/Write Com Port :: C++ Hadi Rezaee26-Dec-01 9:49 Hadi Rezaee 26-Dec-01 9:49  Try CreateFile or OpenFile API functions ...

Felix posted a reply at Programmer's Heaven and mentioned functions: inp(); and outp(); http://www.programmersheaven.com/msgboard/read.asp?Board=3&MsgID=93124&Setting=A9999F0001 Those functions are from conio.h. What do you think about those functions?

What do you think about those functions? They are old and you are probably better of using a modern class-library or perhaps an Active-X component like GreenLeaf CommX. I am in no way connected to Green Leaf but I have successfully used thier products for 10 years on all OS:es from DOS, OS/2 to Windows 3.11/95/NT/2000.

Ramon de Klein's Serial library for C++ 2. PJ Naughter's CSerialPort v1.03 - Serial Port Wrapper (or better on your site, there the newest version). Personally I use the second! Best regards, Eugene Pustovoyt Sonork ID 100.10002:Yaumen Diferences: MFC and Non-MFC valikac28-Dec-01 5:41 valikac 28-Dec-01 5:41  Hey. I read Ramon de Klein's description of Serial library for C++. It sounds good. PJ Naughter's class is a for MFC. What is the difference between, say, Klein's class and Naughter's class? What is the advantage of using MFC and not non-MFC? Kuphryn Re: Read/Write Com Port :: C++ valikac27-Dec-01 6:57 valikac 27-Dec-01 6:57  Okay. I appreciate it. Thanks everyone. Kuphryn Re: Read/Write Com Port :: C++ valikac27-Dec-01 7:02 valikac 27-Dec-01 7:02  C++ Style: ifstream readCOM; readCOM.open(com1, ios::in | ios::binary) char *ptrStore; try { ptrStore = new char[SIZE]; } catch (bad_alloc error) { cerr << error.what(); exit(1); } readCOM.read(reinterpret_cast<char *=""> (ptrStore), SIZE); How do you get the exact size of whatever you're reading from the COM port? It is not a measurable storage container. Do I have to use an MFC class? What is the major difference if I were to use the ifstream and ofstream instead of an MFC class? I have no experience with MFC or windows programming.

Is anybody know how can i correct this problem? Thanks for help. S. Re: Problem with refreshing a dialog box Prashanth Uppunda26-Dec-01 4:18 Prashanth Uppunda 26-Dec-01 4:18  I hope I understood your problem correctly. If you are doing a lenghty process in your application, you can write & call the following function in between the lenghty process, so that the window getts refreshed. void ProcessMessage() { MSG msg; if(::PeekMessage( &msg, NULL, 0, 0, PM_REMOVE )) { ::TranslateMessage(&msg); ::DispatchMessage(&msg); } } However the best way to avoid these problems, I feel is by creating thread for the lenghty process.
