An experiment I ran:
using System;
namespace Test
{
class Foo
{
public int a = 2;
public override string ToString()
{
a = 3;
return a.ToString();
}
}
class Solver
{
public static void Main()
{
Foo x = new Foo();
Console.WriteLine(x.a);
}
}
}
This does indeed print 2 when run, but 3 when debugged, so the debugger definitely calls ToString directly on the object in the given code. While there are other details to fill in about what was happening in my program, this is one thing cleared up.

Hello everyone, first post here, so if you see errors on posting/explaining, make me know to fix it...
What i want to make it's form that parse an INTRANET webpage and bring me data back to show it on labels....
I have tried with HtlmAgilityPack, but it doesn't parse anything of that web, cause its intranet, and i'm doing something that don't fit well. It returns me an error like "specific node can't be null"...
Something like this:
public class Program
{
public static void Main()
{
var html = @"http://html-agility-pack.net/"; HERE GOES MY INTRANET URL, AND NOT THIS.
HtmlWeb web = new HtmlWeb();
var htmlDoc = web.Load(html);
var node = htmlDoc.DocumentNode.SelectSingleNode("//td/span");
}
}
Something like this:
https://imgur.com/uk4Wztd[^]
When click in the button, bring me the especific data.

That makes no sense at all in my limited mind.
You have a webpage, shown in a browser. And now you want a WinForm to fetch those values?

Works as well with internet as well as intranet; there is no difference between those two on that level.

The problem is that people working here shouldn't use internet, but they do. So, we need to take them off of the browser, then putting it on a Winform will make it easier to block them from internet.
Any idea?

Install a firewall.
Building a new GUI does not make sense if you just want to limit access.

Hi i have 3 dropdowns the primary one is filled via jquery ajax request and it fills 2nd dropdown based on seletion and 3rd one is filled after 2nd's selection.
It was previously used Dropdown selected change event which AutoPostBack and gets data from server and page get refresh again and again. Instead of doing this i replace selection change events with jquery ajax calls and its seems fine but now when i click on my search button to fetch data based on selection it loses all dropdown's previous state and reset to default as on fresh page load. Whereas, my repeater remains the data which i had bound on button click. Any help regarding this issue???

That is lousy advice, as a newbie he may want a discussion on how to achieve his requirements.
Redirecting his inquiry from c# to web forum or quick answers may be valid because of the context of the question but to redirect everything to quick answers for a "speedy" response is not valid.
Never underestimate the power of human stupidity

This is the first post for him in Codeproject, may be he is not aware of quick answers section thats why gave a headsup.
since the question is related to json, he might get quick response in QA.

|

I agree with Mycroft, there is nothing wrong with the OP's question being here. And no guarantee that he will get a faster answer in QA.

You have not explained what is wrong with the result, or where you think your code is going wrong. Also, it would really help if you use proper indentation of your code, and the code button to add <pre></pre> tags around your code to make it readable, thus:
public class template_item
{
public string ItemCode { get; set; }
public string WarehouseCode { get; set; }
public string Quantity { get; set; }
public string Price { get; set; }
}

Hello everyone, I kindly ask for an orientation in my code, which is done in C # with Android Debug Bridge (ADB) commands that run at a DOS prompt.
The command basically reads the serial number from my tablet and transfers it to a textBox. Until then, no problem. However I need to copy this serial number from this textBox and transfer it to a new ADB command in DOS to read the battery data. Below is the code for better understanding, the first block is to get the serial number and transfer it to textBox1:
{
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.UseShellExecute = false;
startInfo.RedirectStandardOutput = true;
startInfo.FileName = "adb.exe";
startInfo.Arguments = "get-serialno";
process.StartInfo = startInfo;
process.Start();
string output1 = process.StandardOutput.ReadToEnd();
textBox1.Text = output1;
process.WaitForExit();
}
And the second block is the code that will direct the commands to the serial number:
startInfo.FileName = "adb.exe";
startInfo.Arguments = "-s " + textBox1.Text + " shell dumpsys battery";
process.StartInfo = startInfo;
process.Start();
string output = process.StandardOutput.ReadToEnd();
richTextBox1.Text = output;
process.WaitForExit();
But I can not get it to recognize the variable in the argument line. I've tried to concatenate, without success ... where am I going wrong? What I've already tried, in the searches I've done:
startInfo.Arguments = String.Format(@"/c adb -s ""{0}"" shell dumpsys battery", output1);
startInfo.Arguments = "/c adb -s \"" + output1 + "\" shell dumpsys battery";
startInfo.Arguments = $@"/c adb -s ""{output1}"" shell dumpsys battery";
Thanks a lot!

What is the actual value of the startinfo string when you call Process.Start?
|
|
|
|
|
The value is
e16025f4
If I store this value like this:
startInfo.Arguments = "-s e16025f4 shell dumpsys battery";
It works perfectly!
|
|
|
|
|
No, I mean what is the value of the startInfo.Arguments string when you call process.Start()? Use your debugger to see the exact values when you run the code, not what you think it will be.

Open a command line, and type in the command. Does it work? Try it until that works. Then tell us what you typed in the command line, and we might be able to figure out how to create that command from C#.

Hi, the command I type in command line thats works is this:
-s e16025f4 shell dumpsys battery
I am trying to figure out a way to use a string or anything to copy the text (the serial number text e16025f4) from the textbox and use it in the command line, because this value is dynamic and changes everytime I connect a different tablet or cellphone in the computer.
|
|
|
|
|
Then it is e.g.
startInfo.Arguments = $"-s {output} shell dumpsys battery";
Oh sanctissimi Wilhelmus, Theodorus, et Fredericus!

Hello
I need help to create a simple editor with intellisense in c# (should be used to format SSML files).
I imagine some kind of textbox where the user can write text and when pressing < a dropdown list is shown containing different elements. When an element is selectet the options for the elements is shown when typing (or something like that) and when < is press again the closing element should be shown as the first element in the dropdown list.
I would be nice if new element and options could be added to the editor in a simple way (list or xml file).
I do not know it it makes sense, if - can anyone tell me where to find samples or / opensource for it.

This site actually contains multiple articles on that topic. I'm using Scintilla.NET, as it also works nicely under Ubuntu. Ask Google for details.

I have this method:
private async Task<QualificationTestResult> RunTest(Location bay, IBayQualificationTest test, CancellationTokenSource token, string baySerialNumber)
{
var _logger = new BayQualificationTestLogger(bay, baySerialNumber);
IEnumerable<string> details = null;
var testResult = new QualificationTestResult
{
Name = test.Name,
Version = test.Version,
};
testResult.Result = test.PerformTest(_logger,
((InstrumentService)_instrumentService).GetBayCommunicationService(bay),
token.Token,
out details);
return testResult;
}
I want to run it for a number of different tests, then get all QualificationTestResults back into a list.
So far I have this:
qualificationResult.TestResults.Clear();
IEnumerable<IBayQualificationTest> tests = GetQualificationTests().OrderBy(x => x.Priority).ToList();
List<Task> tasks = new List<Task>();
Task<QualificationTestResult> thermalTask = null;
Task<QualificationTestResult> eSensingTask = null;
var thermal = tests.Where(t => t.Name.ToLower().Contains("therm")).FirstOrDefault();
if (thermal != null)
{
thermalTask = Task.Factory.StartNew(() =>
RunTest(bay, thermal, token, baySerialNumber));
tasks.Add(thermalTask);
}
.
.
.
Task completionTask = Task.WhenAll(tasks);
foreach (var t in tasks)
{
qualificationResult.TestResults.Add(t);
}
This won't compile. On the Factory line I get
Cannot implicitly convert type 'System.Threading.Tasks.Task<System.Threading.Tasks.Task<...Core.Models.QualificationTestResult>>' to 'System.Threading.Tasks.Task<...Core.Models.QualificationTestResult>'
And on the FOR EACH at the bottom, the t.Result errors with "Task does not contain a definition for Result"
This is driving me nuts. What am I doing wrong here???
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
