winforms - Not sure if I'm using "using" correctly c# in tftp app -


I am trying to use the pre-manufactured C # tftp server app with my Windows C # form. In the author server example, which works great, it uses the console app. When I try my console instance with my form in the app then it does not work (no error, just not connected) and I believe my problem is in the "use" statement:

By using 
  (Var Server = New TftpServer ()) {server.OnReadRequest + = New TftpServerEventHandler (server_OnReadRequest); Server.OnWriteRequest + = New TftpServerEventHandler (server_OnWriteRequest); Server.Start (); Console.Read (); }

Not sure I understand correctly but I believe that console is Read () If this is the case, how do I apply equivalent to any form app? I just can not find my head around "use" Sorry, I'm new to C #.

The Windows Forms will always be open until they are explicitly closed. They always keep a thread to read the message queue for user input, so they will not exit the same way from an unnatural console application. In the form of Windows, we need to worry about multithreading and concurrency over console apps. It usually comes naturally, but not always.

Because of this, you can not actually use equal to the console. The user does not request to read () the use of the settlement. If you have done so, then your form will only look insensitive.

However, you are in luck! By using a block in C #, syntax is nothing more than sugar, to remember to call IDisposable.Dispose () to work with an object Later, in a form project, the object can be stored in a class-wide field equal to the server object, then by calling the server. Disk () on, say There is a button. Click the event. This, of course, is just an example. You can also do this on form.closing if it feels more suitable.

High level, you want to do something like this:

  1. Your form class TftpServer server; . Declare a field in
  2. Register a load event and whatever you want for your server to work in your constructor.
  3. Open the server field in the Form_Load event. As events of
  4. Use the server you can see very fit during the life of your form you can worry about concurrency Whether or not this is a case for another question.
  5. Call server.Dispose () in the form of dissection event.

In short, 

  class main: form {private TftpServer server; Public Main () {InitializeComponent (); this. Load + = main_load; Server = new TftpServer (); Server.OnReadRequest + = New TftpServerEventHandler (server_OnReadRequest); Server.OnWriteRequest + = New TftpServerEventHandler (server_OnWriteRequest); } Private Zero main_load (object sender, event aRGS) {server.start (); } Private zero server_onerequire (/ * I did not know about the argument here / /) Use the // read request: to give or receive data (depending on what "read" defines) Private Zero Server_OnrightText (/ * I make sure about debate) / // Use the write request: Give or receive your data (depending on what "write" defines) Safe Override Zero Remove (hair Dispojeng) {if (server! = Null) / / Since settlement can be called many times {server.Dispose (); Server = faucet; }}}

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help?

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
