First you'd need to decide which UI; you could use WinForms on both platforms, GTK or support both.

I've used Visual Studio to create WinForms to be used with Mono. The WinForm implementation differs a tiny bit from the MS implementation, so you will have to test the results.

I'm trying to add a context menu to Watch (and Local) window to Visual Studio (2017). I was able to add the context menu, however I don't know how to obtain the selected item (expression) from the context menu command code.
Thanks Abyss

End the Scheduled Task if it is running for more than couple of hours C# code

Hi,

I have a Console Application which is Scheduled as Scheduled Task, for some reason maybe because of the NetWork issues the Scheduled task is showing running unlimited time and not processing any files or records which are over the network.

Now I want find out in my Console Application if the Task is running and waiting for more than 1 hr send us an Email, can anybody please let me know which approach is better for this, like do we have something in the Windows Scheduler Task to set this setting? Or can I write some code in my Console App to check how long the Task is working for and send an Email or stop it if its too late.

Thanks in advance, any help can be greatly appreciated.

Thanks,

Abdul Aleem

Sounds like a good fit for a watchdog-application; how about simply getting a list of the running tasks and the CPU-utilization? If you notice any application hogging a CPU, you mail.

Doesn't protect you just against your application from going nuts, but other processes as well. Doesn't need a UI, nor much code Smile | :)

how to remove Flag status from Outlook by c# programming or register edit

22-Jun-17 9:44

I got time to do both Smile | :)

using System;
using System.Diagnostics;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Process[] processes = System.Diagnostics.Process.GetProcesses();
            foreach (Process process in processes)
                if (!process.Responding)
                    SendMail(process.ProcessName);

            Console.ReadLine();
        }

        static void SendMail(string who)
        {
            Console.WriteLine(who + " is not responding.");
        }
    }
}

This could be run from the taskscheduler as well, or you may run it in a loop every once in a while. Would depend heavily on what you want from it; you may want to verify that emailing works, and that there is an alternative way to communicate if emailing suddenly fails.

You may want to include other checks, as the Process-class contains more information on the application that is running. Stuff like memory-useage and the debug-output of those Processes[^]. If you decide to guard all applications on hogging cpu and memory, you also have more control over other stuff that may potentially drown out resources for your own application, and effectively an early-warning system for malware Smile | :)

In that case you may want to pass the entire Process-object, instead of just its name like I did. Another sidenote is that the "Responding"-property is used to test whether applications with a GUI are still responsive. You may want to fiddle with the different CPU-time counts, like the TotalProcessorTime. It would probably be more accurate for console-applications.

[SOLVED] Unify Methods; Parameters one or two IEnums<T>

atrus271119-Jun-17 22:02

19-Jun-17 22:02

Hello community,

I'm refactoring a C# application and found 7 (!) methods which do quite the same thing to different parameters. These parameters are LINQ-results.

private void Doit_T(IEnumerable<string> T) {...}
private void Doit_R(IEnumerable<int> R) {...}
private void Doit_C(IEnumerable<int> C) {...}
private void Doit_TR(IEnumerable<string,int> TR) {...}
private void Doit_TC(IEnumerable<string,int> TC) {...}
private void Doit_RC(IEnumerable<int,int> RC) {...}
private void Doit_None() {...}

This sounds like a case for overloading. It would reduce the 7 methods to 5, as there are 5 distinct combinations of parameter types:

private void Doit(IEnumerable<string> T) {...}
private void Doit(IEnumerable<int> R_or_C) {...}
private void Doit(IEnumerable<string,int> TR_or_TC) {...}
private void Doit(IEnumerable<int,int> R_and_C) {...}
private void Doit() {...}

Better than before. But can it get shorter?

As the logics within these methods are quite, but not totally identical, I'd like to unify these methods to just one which "senses" the 7 cases (or gets them passed via a string like "RC" or "T"). The catch is the number and type of arguments of this unified method:
0, 1 or 2 arguments --> optional arguments via default values needed.
different IEnumerable-types --> Generic Approach using IEnumerable<t>.

I lack experience on combining those two needs. What could a "unified" method signature look like?

Thanks
Atrus

There is no IEnumerable<T1, T2> interface in the framework. Did you mean IEnumerable<KeyValuePair<TKey, TValue>>?

atrus2711 wrote:

Without knowing what the methods are doing, that's almost impossible to answer. The obvious suggestion would be:

private void Doit<T>(IEnumerable<T> values) { ... }

That may or may not work, depending on the differences between the methods, and what you mean by IEnumerable<T1, T2>.

my fault, my explanation was too compressed...

Take this excerpt of method Doit_R. It isolates the distinct values of a single column:

var result = SomeList.Select(c => c.IntegerField).Distinct();

Here, result is an IEnumerable<int>.

Doit_RC gathers distinct values of two columns, both ints:

var result = SomeList.Select(c => new { c.IntegerField1, c.IntegerField2}).Distinct();

Here, result is an IEnumerable of an anonymous type, consisting of two ints.

Doit_TR gathers distinct values of two columns, a string and an int:

var result = SomeList.Select(c => new { c.StringField, c.IntegerField}).Distinct();

Here, result is an IEnumerable of an anonymous type, consisting of a string and an int.

A unified method should be able to deal with all of these IEnumerables.
How could this be done?
Thanks Smile | :)

Richard Deeming20-Jun-17 2:25

20-Jun-17 2:25

Something like this?

private void DoIt<TSource, TResult>(IEnumerable<TSource> source, Func<TSource, TResult> selector, IEqualityComparer<TResult> comparer = null)
{
    ...
    var result = source.Select(selector).Distinct(comparer);
    ...
}

DoIt(SomeList, c => c.IntegerField);
DoIt(SomeList, c => new { c.IntegerField1, c.IntegerField2 });
DoIt(SomeList, c => new { c.StringField, c.IntegerField });

edit #1: fixed errors in code example.

Before getting to the question I have about this new syntax/facility, I thought it would be good to review the facility, first ... to establish context.

Using value tuples allows you a neat way to package up a bunch of named values without ALOTT (a lot of tedious typing):

public class Name
{
    public Name(string first = null, string middle = null, string last = null)
    {
        FirstName = first;
        MiddleName  = middle;
        LastName = last;
    }
    
    public String FirstName { set; get; }
    public String MiddleName { set; get; }
    public String LastName { set; get; }

    // return type is value tuple
    public (string first, string middle, string last) FullName
    {
        set
        {
            FirstName = value.first;
            MiddleName = value.middle;
            LastName = value.last;
        }
        
        get { return (first: FirstName, middle: MiddleName, last: LastName); }
    }
}

Use example:

Name nametest1 = new Name(first: "john", last: "doe");

var fullname1 = nametest1.FullName; // return value is value tuple

string lastname1 = fullname1.last;

Name nametest2 = new Name();

nametest2.FullName = ("judy","a.", "doe"); // setting value using value tuple

var fullname2 = nametest2.FullName;

string lastname2 = fullname2.last;

I'm curious to know if you intend to make use of this new language facility, and whether you see any advantages to doing so compared to returning a class, or struct, instance. Any gotchas you see in terms of multi-threading, etc. ?

thanks, Bill

I don't love it. I can see it degenerating quickly in spaghetti-code; but then I generally avoid standard Tuples anyway in favor of interfaces.

I don't think there are more concurrency issues than you would see with a standard property accessor. There are definitely new gotchas when implementing property update events.

I think this is just another functional feature being stitched in. I don't think this really helps out OOP at all.

Thanks; I would be interested in seeing a code sample using an Interface that is an alternative to use of a Tuple.

That seems right; the fact you can't make the objects in a ValueTuple immutable means at some point an internal value can be changed, and then, the ValueTuple may be out of synch with whatever sources it was built from.

It's not any more complicated than you think.

interface IExample{
   int Number {get;set}
   string Text {get;set;}
}

Tuple<int,string> ExampleTuple;
IExample ExampleImplementation;

I've just always felt that Tuples are a quick workaround when you don't have a proper system (or module) design. I think they're fine for proof-of-concept, but avoid them like the plague in production code for maintainability reasons.

First gotcha is that you omit XML documentation on a member. Your fullname, does it include the birthnames, does it include a title, what?

How is it more readable than returning a known structure? And does it justify the money saved on 'typing'?
