How can a collection of written files be maintained in Settings.settings? List<string> or AttachmentCollectionbut the studio doesn't allow any of these types to be selected in "type."

var stringCollection = new System.Collections.Specialized.StringCollection { "attachment1", "attachment2" };
        Properties.Settings.Default.Setting = stringCollection;
        Properties.Settings.Default.Save();

The problem of not showing the line jumps I have solved by changing in the PHP code, in the msjCorreo the PHP line jumps "\r\n" by the HTML HTML label "≤ br/2005" since the content type is text/html so it is received as html.

Try using. System.Data.SqlClient.SqlParameter♪ Example:var ColumnsNames = new List<string>(){"id","Name","DateIn","DateOut","HotelNo"}; List<Dictionary<string, object>> rows = new List<Dictionary<string, object>>(); string query = @"SELECT id, Name, DateIn, DateOut, HotelNo FROM hotel WHERE DateOut = @DateOut"; DateTime _date = DateTime.Now;//как пример значения времени using (SqlCommand Query = myconnect.CreateCommand()) { Query.CommandText = query; SqlParameter _par = new SqlParameter(); _par.ParameterName = "@DateOut"; _par.DbType = DbType.DateTime; _par.Value = _date; Query.Parameters.Add(_par); using (SqlDataReader reader = Query.ExecuteReader()) { while (reader.Read()) { Dictionary<string, object> row = new Dictionary<string, object>(); for (int n = 0; n < ColumnsNames.Length; n++) { row.Add(ColumnsNames[n], reader.GetValue(n)); } rows.Add(row); } reader.Close(); } }

All necessary forms (or any object) should be transmitted to the designer:public partial class Form1 { public Form1(string text) { InitializeComponents(); richTextBox1.Text = text; } } //------------------------------- ... var form = Form1("some message"); UPDAlso in class. Form I've got my own. Ownerthat you can take the form holder. Ultimately, the subsidiary form will have access to the parent through this characteristic.

You can use the https://msdn.microsoft.com/pt-br/library/gg480740(v=vs.118).aspx so that there is no HTML encoding in the string.It would be like this:<input type="text" class="famo-input famo-text-10" name="cost" value="@Html.Raw(Model.KnowAcquisition.Cost.HasValue ? Model.KnowAcquisition.Cost.Value.ToString("n2", CultureInfo.CurrentCulture).ToString() : string.Empty)" /> Try also, as follows (using https://msdn.microsoft.com/pt-BR/library/7c5fyk1k(v=vs.110).aspx ), if the string is already encoded for HTML:<input type="text" class="famo-input famo-text-10" name="cost" value="@Html.Raw(Model.KnowAcquisition.Cost.HasValue ? HttpUtility.HtmlDecode(Model.KnowAcquisition.Cost.Value.ToString("n2", CultureInfo.CurrentCulture).ToString()) : string.Empty)" />

No, they're in different branches of inheritance. Collection No standard implementation List not inherited Set♪ And if you're using one of these realities in the initials, you'll get one. ClasslCastException♪ Only if your collection runs both of these interfaces is the kind of thing that works.

Window.AllowsTransparency value true.Window.WindowStyle noneSet a transparent colour (transparent colour, alpha-canal value equal to zero) for the background. Or make it possible to use a visual on the background that has transparent areas (with zero alpha-canal value).These three steps effectively remove the standard outside view of the window. In order to ensure the window effect of an unusual form, there is a need for some non-transparent contents with the required shape.Source: https://professorweb.ru/my/WPF/UI_WPF/level23/23_5.php ♪

To begin with, my opinion regarding adding a variable for the threshold is a sign yes. I explain, the project itself aims to light a focus (called actuator) controlled by humidity (called sensor) and whose control variable in this case will be the threshold. That said, control over this actuator will always depend on the control variable which tells us that we will always need a control variable with an assigned value. Thus, the user who uses the project you present will need to know where the threshold is, as in case of need it can adjust it (what is called calibration). This also tells us that it will be necessary to have a default value when the Arduino (the default value you comment on) is lit.In the Arduino you will also need to receive such data, always considering that the function https://www.arduino.cc/reference/en/language/functions/communication/serial/read/ returns the first Byte of the plot. It is recommended that you find examples of how to read serial port data in Arduino. Once the information that comes from the serial port has been processed, update the threshold control variable with that value and forward it to the serial port to inform the user that the change has been made.I know the answer is somewhat theoretical, if you need more technical help, don't hesitate to ask

The sender contactes some ports, usually not indicating which is free, the system will give and call the recipient by indicating the address and port.There is no link between the port of departure and the recipient. The receiver is listening to an advertised port ( say smtp 25) or ports (whether with SSL or whatever), but he is not obligated and unable to listen to all ports to which he is treated.

There's a lot of ways to do, depending on the way forward. The main ones are the database, store in the file, the preferences, and if it's not variable data, the string resources, if the data don't change, then the last option for you is perfect, so...<string-array name="my_string_array"> <item>one</item> <item>two</item> <item>three</item> </string-array> Here we go:String[] stringArray = getResources().getStringArray(R.array.my_string_array);

I've come to this structure of the decision. It is a basic structure that contains only the most necessary. Then, of course, we need to fill it with our models.Solution |- Domain.Models | |- User | |- Domain.Services | |- IUnitOfWork | |- ApplicationServices | |- IUserService | |- Infrastructure | |- Data | | |- DatabaseContext | | |- UnitOfWork | | | |- DBO | | |- ApplicationUser | | |- UserProfile | | | |- Services | |- UserService | |- ASP.NET MVC Project Domain.Models - it's a model of the subject area, with the business logic.IUserService - it's a user interface that has "Registration" techniques, "Income," "Income"User and DBO - I'm in the D.O.S.S. separate profile of the laser and model Identity, mapping. This is done to ensure that Domain does not depend on IdentityUserUserService - implementation IUserServicethe logic of registration, entrance, etc. Then using Dependency Injection to introduce the interface. IUserService to your counterallers or other services.NoteLet's say IUserService approximately:public interface IUserService { Task Register(RegisterModel user, bool isPersist = false); Task Login(LoginModel user); Task Logout(); } There's.RegisterModelLoginModelIf it were in the same project, they would definitely be ViewModels. But that's the level. ApplicationServices It doesn't depend on ASP. The NET project, the species cannot be used. I see two options:Put them in. Domain (not too ideologically correct)Explain them where they use their interface. ApplicationServices

You could implement something like beingpublic List<VistaRestaurantSearch> SearchRestaurant(int RestaurantID) { var query = (from de in se.DeliveryConfiguration join re in se.restaurant on de.Restaurantid equals re.RestaurantID where re.RestaurantID == RestaurantID select new{ Delivery = se, Restaurant = re }).ToList(); var rest = query.Select(x=> new VistaRestaurantSearch() { restaurant = x.Restaurant, config = se.DeliveryConfiguration.Where(a => a.Restaurantid == x.Restaurant.RestaurantID).FirstOrDefault(), Horary = new EngineRestaurant().getRestaurantHourbyRestaurant(x.Restaurant.RestaurantID), prom = new EngineReview().getReviewAverage(x.Restaurant.RestaurantID) }).ToList(); return rest; } You don't need to perform a foreach of the response of the linq to transform into another entity, you perform it directly in the selectAlso to complete the properties Horary and prom You can't join the other boards to solve it, so you don't have to go to the other classes and solve it in a single query
