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";

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.

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<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.Result);
}
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.

If the calling method is async:
QualificationTestResult[] results = await Task.WhenAll(tasks);
If it's not:
QualificationTestResult[] results = Task.WhenAll(tasks).GetAwaiter().GetResult();

Richard Deeming wrote: QualificationTestResult[] results = Task.WhenAll(tasks).GetAwaiter().GetResult();
This fails to compile with "Cannot implicitly convert type 'void' to QualificationTestResult[]"
[UPDATE]
This works
try
{
Task.WaitAll(tasks.ToArray());
}
catch (Exception e)
{
}
foreach (var task in tasks)
{
var result = ((Task<QualificationTestResult>)task).Result;
qualificationResult.TestResults.Add(result);
}

Ah, sorry - one more change to make it work:
List<Task<QualificationTestResult>> tasks = new List<Task<QualificationTestResult>>();

Just gonna throw a simple TPL Dataflow answer out there, since I've been having such a blast with it. Of course it loses a lot of it's utility since it's not part of a pipeline.
var xform = new TransformBlock<IBayQualificationTest,QualificationTestResult>(
thermal => {
try {
qualificationResult.TestResults.Add(RunTest(bay, thermal, token, baySerialNumber));
}catch{}
});
tests.Where(t => t.Name.ToLower().Contains("therm"))Select(x => xform.Post(x));
xform.Complete();
xform.Completion().Wait();

I have an ObservableCollection bound to a collection of DatabaseTypeEntity. On the DatabaseTypeEntity is a string called "DatabaseTypeName".
I want to be able to insert a new item into the list so that it is alphabetical. How would you find the list's InsertAt index using the DatabaseTypeName?
Thanks

Maybe you misunderstood my question.
I'm trying to find the alphabetical index position of where to insert an item.
So if I have
"An item"
"My Item"
"Some stuff"
and I want to insert "New Item", then it should have index position of 2 and be inserted between M and S.
[Update]
I could simply add it to the list, then do
DatabaseItems = new ObservableCollection(myTempList.OrderBy(x => x.DatabaseTypeName))
but this will recreate the list every time. It's cheaper to insert the new item into the list at the position it belongs at. I'm just not sure how to find that position
If it's not broken, fix it until it is.

There's no such thing.
You would have to write the code to determine the insert location. The quick'n'dirty method would be to just for(index...) over the collection until you find the alphabetical position and then do an Insert(index, object) to insert into the collection. Keep in mind, this doesn't scale well. The larger the collection, the more expensive this operation becomes.
Really, if an alphabetical collection had to be maintained, I would probably write my own version of ObservableCollection and add the support to it along with b-tree support to keep the CPU workload down when inserting items.
But, I really wouldn't do that because a "sorted view" is the realm of the view of the collection, not of the collection itself.

I guess a SortedSet<t> would work.
I'll give it a try

Your current list l :
{"A","C","D"}
your instruction:
l.Add("B");
your new list l :
{"A","B","C","D"}
I believe that this is what's your mind trying to achieve.
In fact, I can only think of 2 appropriate ways to fulfil such a task.
1. SORT IT:
Yes, just add your new item normally. Once you do, sort your collection.
Tip: do not call the sorting instruction each time you update the ObservaleCollection, do it once you add all your items.
c# - How to sort ObservableCollection alphabetically? - Stack Overflow[^]
2. PLAY WITH IT:
Write a for loop that runs through the contents of your ObservableCollection. Within each step, a comparison will be done. You will compare your new item's name with each item, once you find a match, push all your items starting from that position to the right side of your collection.
Sample:
Here is your list:
• A
• C
you add a new item: l.Add("B"):
• A
•
• C
the C got pushed down because C's position is greater than B's.
C's old position will be reserved, B will be added to it.
• A
• B
• C

Use design patterns in the game and ensure a rollback
Send a console implementation of the game patches. Ensure that the size of the field is selected and the level of difficulty (how much the board differs from the state of the "victory"), make it possible for the game to become more complicated when a certain amount of random moves takes place instead of the user's turn. Realize the possibility of canceling moves.
The patterns are expected: Singleton, Factory method, Team, Memento.
