In my experience, "ports" need to be somewhat "stable".
You can't arbitrarily open and close them without expecting a few "connection" fails.
I typically create a single instance for a port in a "longer running" app (including "weighing"), and share that instance; I don't keep opening and closing the port.
Weigh scales also need "wait" times to "center" and respond, etc. At least 100 ms.
I can't picture your scenario as being realistic: repeatedly loading a form to perform a "weighing".

Hi Dear,
I'm confused about my semester project, Kindly give me some GUI based projects suggestion which can be implemented in C#. I have already done Chatting APP using Client Server Protocol in Java Language and have done many times Management System, In this semester I want to do something new Please Suggested me the projects.
Thanks.

Go to the CodeProject Articles section, where you will find many suggestions & ideas. But be careful not to copy the code, and submit it as your own work.

thanks for your advise I will remember your words and appreciate your suggestion !

Write a web crawler that crawls the internet looking for student project ideas.
Speed of sound - 1100 ft/sec
Speed of light - 186,000 mi/sec
Speed of stupid - instantaneous.

how it is possible like web crawler in C#? I think it can be possible in ASP.NET not in the C#
|
|
|
|
|
What do you think ASP.NET uses? It's either using C# or VB.NET.

ASP.NET is just a web framework. Underneath, any of the .NET languages can be used with it - this means that these languages have access to the framework features that ASP.NET uses. For instance, you can use the HttpClient class to make a HTTP request directly from C#.

Do you want to do that in Java again? If so, this is wrong forum, if not then you can rebuild the same and explain how Java and C# APIs differ in networking programming. Pretty simple?
In case, you want to do the project in Java, try adding a bit of security. End-to-end encryption is a new feature in almost every chat application, you can show you to implement that in the project you built last time. There is no harm in this in academics, I say.

Thanks for you suggestion, I want to try some new ideas instead adding feature in old one. I'm quite interested in Jarvis AI. I have read some where that It's possible and Already done in Arduino Projects by using the EMBEDDED COMPUTER ?.

What are you interested in; what are your future job-market goals ?
Where do see yourself as needing to improve your skills and understanding: data-structures and databases ? algorithms and problem analysis ? visual user interaction ? web/cloud ?
To help you find what you need is possible; but, you need to find who you are.

Actually I'm not here to be convince who am I !
Just need suggestion, I don't expect anything from the future I believe in the present, so just suggest me your ideas instead of motivational comments, Well I'm quite interested to build the Jarvis Like Mark build it for his home automation.

Unless you take the initiative to develop your own ideas, you will learn nothing.

I want to get the Record in Web form by clicking on select button on each Row
I mean i want to select the data from grid view from each row and other thing i want that is the form of that perticlur grid filled automatically so that i can edit it and update the data . hope u got me all of u Please help me
i know grid view has a select button so that each row is selected i want selected data in form not in grid view
|

You can get the controls of grid on button click event.
GridViewRow gvr = ((Button)sender).NamingContainer as GridViewRow; will get the row for you..
All you need to do is to get the values of controls in grid and pass their values to your form controls.
like .... Label lbl = gvr.FindControl("lbl") as Label.... and you will get the value of your row selected ..
Hope this helps

I want convert Dictionary Net 4.0 to Net 2.0.
Dictionary<string, Action<IWin32Window>> ItemHandlers = new Dictionary<string, Action<IWin32Window>>() {
{ "A", o => MessageBox.Show(o, "The command A is executed", "Dx Sample", MessageBoxButtons.OK, MessageBoxIcon.Information) },
{ "B", o => MessageBox.Show(o, "The command B is executed", "Dx Sample", MessageBoxButtons.OK, MessageBoxIcon.Information) }
};

The problem with this code is that it's using a collection initializer which wasn't introduced until Visual Studio 2008. Fortunately, this is a simple enough fix, you just move the initialization out and use Add instead.
Dictionary<string, Action<IWin32Window>> ItemHandlers = new Dictionary<string, Action<IWin32Window>>();
ItemHandlers.Add("A", o => MessageBox.Show(o, "The command A is executed", "Dx Sample", MessageBoxButtons.OK, MessageBoxIcon.Information));
ItemHandlers.Add("B", o => MessageBox.Show(o, "The command B is executed", "Dx Sample", MessageBoxButtons.OK, MessageBoxIcon.Information));

Nobody for sure is going to write such a c# code:
public class omg
{
public omg()
{
do_criminal_switch();
}
public void do_criminal_switch()
{
switch (0)
{
case 0:
break;
}
}
}
do you think that the C# parser should notice and whip the programmer for this shining piece of code or should continue as nothing happened with a const as switch argument?

Why should the compiler punish someone for doing this? Suppose they had just put that code in as a placeholder while they wrote some tests, why should the compiler cause them issues.

If you'd want that, install FxCop and activate the rule. If there is none, feel free to write it.

It is not the compiler's job to comment on your code. The compiler is supposed to take well-defined code (under the rules of the language), and compile it. As this code is well-defined, the compiler should simply compile it.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

That's not quite true: it does comment on really dumb code such as:
while (x > 0);
{
...
x--;
}It'll (thankfully) tell you "Possible mistaken empty statement" because of the spurious semicolon. And we've all done that one! 
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

I stand corrected. 
However, I believe that there is a big difference between "micro-errors" such as your example (a single character in the wrong place) and criticizing the utility of a whole block of code. At some stage, the compiler must assume that what the programmer wrote is what he/she/it meant.
