Socket communication (Winsock), interop ... devvvy19-Jul-07 15:30 devvvy 19-Jul-07 15:30  I have one server implemented in WIN32 C++. I want to build another server to communicate (Winsock) with this WIN32 server in C#/.NET using Winsock However I am worried about incompatibility - haven't done Winsock before not sure if things like wiring a custom class over Winsock can be a problem because two ends are implemented in two languages (C++ and C#) and two framework (WIN32 and .NET) Any suggestion? Re: Socket communication (Winsock), interop ... originSH19-Jul-07 21:59 originSH 19-Jul-07 21:59  Why not just use the sockets stuff in .Net? You don't have to use the same network libaries at each end, tcp/ip has the same protocols no magtter what Re: Socket communication (Winsock), interop ... devvvy20-Jul-07 3:15 devvvy 20-Jul-07 3:15  originSH wrote: Why not just use the sockets stuff in .Net? That'd work huh? I never try this, can I wire a C++ class from WIN32 server, then on receiving end (our C# server) read off the socket...? I have a feeling probably intrinsic types would do just fine but ... Thanks Re: Socket communication (Winsock), interop ... originSH20-Jul-07 4:10 originSH 20-Jul-07 4:10  There are several layers to network communications. Everything up to network protocol (i.e. tcp/ip most of the time) is standard. You then have the communications protocol on top of this which can be standard if implimenting an existing one (i.e. the hidious IRC RFC 1459[^]) or custom if your making it yourself. How you send the data over the communication protocol is what your dealing with here and will govern if (or rather how easily) different frameworks and languages can talk to each other. To send a class over you would have to serialize it at the one end and deserialize it at the other. If you have a serializer in C++ and a deserializer in C# that will work together then it'll be all good How are you serializing the class at the c++ end? Re: Socket communication (Winsock), interop ... devvvy20-Jul-07 22:31 devvvy 20-Jul-07 22:31  yes planning on wiring down a vanilla C++ class I think my C# server will have to linked+interop with a WIN32 C++ dll (perhaps wrapped by C++ managed/.net dll) ... hope this will work Re: Socket communication (Winsock), interop ... originSH23-Jul-07 12:10 originSH 23-Jul-07 12:10  I'de definatly go the route of C++/Cli if you have VS2k5 ... it's great for this sorta stuff Re: Socket communication (Winsock), interop ... pbraun20-Jul-07 9:12 pbraun 20-Jul-07 9:12  I used to work on a system that relied upon a .Net application communicating via Tcp/IP with a Win32 C++ server. It works and I found no problems with it. Ok, as for the design, well you'll have to designate one of the applications as the server and one as the client. That way they can communicate. Otherwise you will have to implement both a client and a server in each application. Look for the C# Chat application article on this web site. That should help.

The user is capable of choosing a particular vehicleName from a dropdown list and the chosen vehicle attributes get listed on the PropertyGrid. Since, these vehicle objects are dynamically moving, their attribute - 'fuel_remaining' continuously reduces. But, on the PropertyGrid, the value of the GridItem related to 'fuel_remaining' updates only at the instant when I choose the vehilceName from the dropdown list. If I have to see the updated value again, I have to choose the vehicleName again from the list. Is there anyway where I can program it to show the continuously changing value for that attribute field from just one selection of the particular vehicleName from the list? Thanks for the help, if anyone can provide. .xml documentation jon-8019-Jul-07 11:19 jon-80 19-Jul-07 11:19  I'm trying to compile test code with VS 2005 so that it generates xml documentation, however, only part of the tags are being generated.

Furthermore at least one of the Visual Studio versions has a bug, resulting in the omission of all comments on properties.

When adding eventhandlers to events, what's the difference between: foo.SomeEvent += Bar.OnSomeEvent; ...and... foo.SomeEvent += new EventHandler ( Bar.OnSomeEvent ); ? Thanks. Re: Adding EventHandler MidwestLimey19-Jul-07 11:08 MidwestLimey 19-Jul-07 11:08  In the first case the compiler type checks that Bar.OnSomeEvent has the same delegate type as SomeEvent and inserts the Delegate.Combine call with the inferred delegate type. In the second, you're doing part of the compilers work yourself by explicitly telling it the delegate type. The msil code for both will be identical. I'm largely language agnostic After a while they all bug me Re: Adding EventHandler mmfranke19-Jul-07 11:15 mmfranke 19-Jul-07 11:15  OK, thanks. So why are most of the samples I see written the second way? The first way is leaner. Is this some sort of leftover from older coding practices or something? Maybe .NET 1.x? Thanks again. Mike Re: Adding EventHandler MidwestLimey19-Jul-07 11:16 MidwestLimey 19-Jul-07 11:16  It's a left over from 1.0 or 1.1, can't remember when they changed it.

Sepharo19-Jul-07 9:58 Sepharo 19-Jul-07 9:58  How do applications get permission to create keys hkey_classes_root? Using Registry.ClassesRoot.CreateSubKey(...) I am able to add registry keys, however I wasn't able to until I messed around with the permissions in the registry. But I've installed other applications from the very same account before without changing permissions and those applications were able to add their owns keys to classes_root. So the question is how do they do that? What code do I need to add to be able to let my program write to classes_root without the user who installs the program having full access? Creating Tools > Options window student_rhr19-Jul-07 9:47 student_rhr 19-Jul-07 9:47  I am strugling with creating an Options Window (like how you go to Tools > Options and a window pops up with options in it). Does any one know of a way to create this type of windows? Any Ideas, link to an article / white paper etc will be highly appreciated. Thanks. Re: Creating Tools > Options window Paul Conrad19-Jul-07 10:41 Paul Conrad 19-Jul-07 10:41  Just create a new form with the options, and from your main form button/menu item click/whatever, call it up. Nothing much really to it. "Any sort of work in VB6 is bound to provide several WTF moments." - Christian Graus Re: Creating Tools > Options window BoneSoft19-Jul-07 10:45 BoneSoft 19-Jul-07 10:45  The window's not hard, you do that like any other window. What you need to decide is what all you will show, how you will store choices, and how the rest of you app reads and responds to those choices. I assume that's what you're talking about. I don't know of an article specificly dealing with that, though many may have something like that built into articles about other topics. Personally, I'd use XML serialization: decide what options to offer, build an XML structure to house them, make your options form address those options, read your config, and write to it. Then I'd probably have the host form show it as a dialog [optwin.ShowDialog()], and make it expose your XML serializable config object as a property so that the host can get the options directly from the options form. And make your host form look for the config on load to initially respond to saved options. But there are a number of things to consider and work out with this. Clear as mud?
