Enquiries to Reverend Christian Graus Question about CSocket nachilau18-Sep-02 9:36 nachilau 18-Sep-02 9:36  Hello, When I am declaring CSocket in VC++, what .lib should I include in the link? Thanks! Nachi Re: Question about CSocket Daniel Turini18-Sep-02 9:56 Daniel Turini 18-Sep-02 9:56  Normally, only MFC libraries will suffice. If you're developing your own CSocket, you can #pragma comment(lib, "ws2_32.lib") Concussus surgo. When struck I rise. How to make an Incomming connection Joe O'Connor18-Sep-02 9:02 Joe O'Connor 18-Sep-02 9:02  In WinXp/2k (using c/c++) is it possible to setup an Incomming Connection and delete at a later date, to allow a mobile device to connect to the PC. I know it is possible via the Network Connections properties, but I need to do it in code, as the program should only allow incomming connections at certain points in the program. (See http://www.microsoft.com/windowsxp/home/using/productdoc/en/default.asp?url=/windowsxp/home/using/productdoc/en/howto_conn_direct.asp[^] for more info). Any help atall would be nice. how to debug a VB dll called from VC ns18-Sep-02 8:59 ns 18-Sep-02 8:59  For that matter I dont know how one can debug a VC dll called from VC. But at the moment I have a VB dll that I'm calling from VC. I'm putting msgboxes in the dll and rebuilding each time, but its really inefficient. How to do this the right way? Thanks, ns A little more detail maybe? Joel Holdsworth18-Sep-02 8:58 Joel Holdsworth 18-Sep-02 8:58  We don't really understand where your orblem lies, or did you mean to reply to someone?

I need to know how one can "step into" the code of a VB dll called from VC to see whats wrong. Is this even possible? (Can this be done if VC is calling a VC dll? ). I am suspecting that the private declares in my VB dLL may need to be changed to public but I dont know VB so I am off to investigate. Hope I'm clearer this time Re: A little more detail maybe? Joel Holdsworth18-Sep-02 9:09 Joel Holdsworth 18-Sep-02 9:09  Hi Again, In my memory, isn't visual basic separte from the dev studio ide? consequently if you do try and step into a VC dll, you'll be confronted with assembly instructions. So you may be up the creak there. Unless you can convince VB to make your VC program the executing program for your dll. So you ask VB to run the DLL by running the C++ program, in which case you can make it halt just at the beginning of the appropriate function. Failing that I think you are reduced to making your dll flash up MessageBoxes to trace out the problem! Sorry I don't know anything more useful... With time we live, with money we spend!

You go into your VB project settings and tell the compiler to generate debug info (.dbg-files I think), and you have to turn optimation off. Then you place the .dbg-files and your dll in the same place, and from the VC debugger you just step into the code. The first time you do that, it asks for the VB source. Works perfectly fine, I have done it a couple of times with COM Objects written in VB... - Anders Money talks, but all mine ever says is "Goodbye!"

Joel Holdsworth18-Sep-02 8:50 Joel Holdsworth 18-Sep-02 8:50  Hi Everyone, The clue's in the title of this post! Does anyone know of a free open source windows C++ compiler and that will interface with MSVC compiled dlls? I know its a tall order, but I was hoping you guys would rise to the challenge. The reason is that I'm making a totally flexible image making program, which is composed of user coded units, which are compiled at runtime, so it will allow users to do graphics programming simply like they did in the dos days, but with a whole lot more power to play with! The system works really well using the MS compiler, problem is that MS will not be impressed if I distribute copies of this program with their compielr included, so does anyone know of an alternative? Thanks for your time.... With time we live, with money we spend! Joel Holdsworth. Re: Free open source windows C++ compiler? Joel Holdsworth18-Sep-02 9:26 Joel Holdsworth 18-Sep-02 9:26  Hi Thanks for your a lot input. I'm very impressed by that compiler of yours. It could well become part of my program! It is quite important that the compiler can deal with C++, because I exploit the object orientation and inheriatance heavily, so its not just a case of finding a C compatible compiler...

What will actually happen? If the answer is buffer overflow, then, is it mean the later message will overwrite the earlier message? Nachi Re: Another question about winsock Anders Molin18-Sep-02 9:57 Anders Molin 18-Sep-02 9:57  Nothing will happen, the computer a will fail to connect - Anders Money talks, but all mine ever says is "Goodbye!" Re: Another question about winsock valikac18-Sep-02 11:52 valikac 18-Sep-02 11:52  Realistically what ultimately occurs if one systems continues sendng packets to another system is a network overflow. In otherwise, the sending system floods the networking connection of the receiving system. In an non-blocking I/O model, the receiving system will continue getting incoming messages. Kuphryn CoInitialize and COM ns18-Sep-02 8:45 ns 18-Sep-02 8:45  Using #import statement (calling a VB dll from VC) I have a database app which uses CoInitialize (MFC MDI). Now i want to add another menu item which also will be calling CoInitialize but for a different com library. Is there any danger here with multiple CoInitialize? Also, in my main prj at one place I had (at one time) two #imports but only one CoInitialize. MSDN is cryptic and I;m not too clear about it. At some time I recall someone cautioning against multiple CoInitialize... Thanks, ns Re: CoInitialize and COM Stephane Rodriguez.18-Sep-02 8:54 Stephane Rodriguez. 18-Sep-02 8:54  CoInitialize(x) increments a counter, so the worst thing you face is a running object table not cleaned up when the app quits (number of CoUninitialize do not equal number of CoInitialize). Worth knowing is that each new thread requires a separate CoInitialize(x) call.

Re: CoInitialize and COM ns18-Sep-02 8:57 ns 18-Sep-02 8:57  I have a single threaded app, but 2 #import statements for two different dlls. CoUninitialise is balanced so I guess its okay (I hope). By thread you didnt mean function right? But an actual thread? Thanks, ns Re: CoInitialize and COM Stephane Rodriguez.18-Sep-02 9:06 Stephane Rodriguez. 18-Sep-02 9:06  Yes I mean an actual thread. And I don't see the point with #import (this preprocessing compiler directive produces smartptr interfaces from the type-library : there is no CoInitialize call in here).
