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

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 Smile | :)

How are you serializing the class at the c++ end?

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

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.

.NET server hasn't been implemented --- to be on the safe side I probably would do it in managed C++ rather than C# so chances of problem in deserialization of the wired C++ class from WIN32 server would be minimize.

PropertyGridItem -Dynamic Value Updates

mastmast19-Jul-07 13:19

I am writing an application in which vehicles are moving on their pre-assigned route. 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.

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. Why?

Math.cs:
// Math.csnamespace Wrox.ProCSharp.Basics{///

public class Math{///

/// The Add method allows us to add two integers///

///<returns>Result of the addition (int)///<param name="”x”" />First number to add///<param name="”y”" />Second number to addpublic int Add(int x, int y){return x + y;}}}

I believe it enables the thingy that allows you to expand/collapse xml nodes when viewed in IE.

Hi,

the structured comments that optionally get collected into an XML documentation file
need some special keywords, such as summary, returns, remarks.

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

Adding EventHandler

Hi.

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

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

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.

It is only C# 2.0 (hence .NET versions >= 2.0) that support the shorthand notation.

How do applications get permission to create keys hkey_classes_root?

Sepharo19-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

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.

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.

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?

Yes I am.

pretty much!!

I have the settings for my applications stored in the MyApp.settings file. Would that be a bad idea?

Also, when the settings are changed i.e. user has changed some stuff in the options window, the parent form doesn't autmatically apply the changes. For it to apply changes does it have to be "refreshed" or "reloaded"?

There's nothing wrong with using app.settings.

For the app to take advantage of setting changes, you can have the host form get the settings from the options form before it is disposed, or read them from your app.settings file after the options form is closed.

private void ChangeSettings() {
    MyOptionsForm mof = new MyOptionsForm();
    // show your settings form as a dialog
    // this line will show the form, and get the result when it closes
    // but you still have the mof reference to it, and can access it's
    // public properties.
    if (mof.ShowDialog() == DialogResult.OK) {
        // Make Setting Changes Here
        // Expose setting properties from MyOptionsForm
        // or re-read your settings file here.
    }
}

That help?
