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???

dear friends,
I'm new in Json, I need some help
here's the data:

{

"PostingDate": "2017-05-17",
"DocDueDate": "2017-05-17",
"TaxDate": "2017-05-17",

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.

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.

Trying to use a string to adb command line

4-Oct-17 22:33

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! Big Grin | :-D

What is the actual value of the startinfo string when you call Process.Start?

Cláudio Hideki4-Oct-17 23:40

Cláudio Hideki

4-Oct-17 23:40

The value is

e16025f4

If I store this value like this:

startInfo.Arguments = "-s e16025f4 shell dumpsys battery";

It works perfectly!

Richard MacCutchan4-Oct-17 23:50

4-Oct-17 23:50

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.

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.

Run List Of Tasks, Then Get All Results

Kevin Marois2-Oct-17 12:51

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 of tasks to complete
List<Task> tasks = new List<Task>();
Task<QualificationTestResult> thermalTask = null;
Task<QualificationTestResult> eSensingTask = null;

// Launch the Thermal test in it's own task
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);
}

// Launch other tests here, just like the Thermal, test above
.
.
.

// Wait for all tasks to complete
Task completionTask = Task.WhenAll(tasks);

// Put all results into the list of results
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.

At a first pass, drop the async from your test method. It's not neccessary because you aren't awaiting anything in that method. Then, you can remove the Task part of it so you're only returning the QualificationTestResult. As you are creating your own external Task for this using the TaskFactory methods, you don't need to make that method return a Task.

OK, that fixed the Task.Factory problem..

Now, how do I get the results from all the tasks. here's what I have so far

qualificationResult.TestResults.Clear();

IEnumerable<IBayQualificationTest> tests = GetQualificationTests().OrderBy(x => x.Priority).ToList();

// List of tasks to complete
List<Task> tasks = new List<Task>();
Task<QualificationTestResult> thermalTask = null;
Task<QualificationTestResult> eSensingTask = null;

// Launch the Thermal test in it's own task
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);
};

// Launch other tests here, just like the Theram, test above

// Wait for all tasks to complete
Task completionTask = Task.WhenAll(tasks);

// Put all results into the list of results
foreach (var t in tasks)
{
    qualificationResult.TestResults.Add(t.Result);  // HOW DO I GET THE RESULT FROM EACH TASK 
}

The last part won't compile. Tells me there is no "Result" on the task.

If it's not broken, fix it until it is.
Everything makes sense in someone's mind.

If the calling method is async:

QualificationTestResult[] results = await Task.WhenAll(tasks);

If it's not:

QualificationTestResult[] results = Task.WhenAll(tasks).GetAwaiter().GetResult();
