Good day, gentlemen, I have a game where the buttons come and the user has to press them and for that, he'll get the glasses, the buttons just come and disappear, and every button has a picture of itself and needs to be no frame around that image.

I'd rather use the code instead of the picture for the visual.
If you need to remove the frame from the button, so:
```
button.FlatAppearance.BorderSize = 0;
button.FlatStyle = FlatStyle.Flat;
```

We need to record a variable (or object field) which one of the fires is active when switch switching for an old active frimet. pack_forgetfor a new, active pack (or grid_forget/gridif the fires are arranged with help grid)Example (cyclical switching between three frams):import tkinter as tk class App(tk.Tk): def init(self, *args, **kwargs): super().init(*args, **kwargs) self.frames = [] self.add_frame(text="Frame 1") self.add_frame(text="Frame 2") self.add_frame(text="Frame 3") tk.Button(self, text="Next frame", command=self.next_frame).pack() self.active_frame = 0 self.frames[self.active_frame].pack() def add_frame(self, text): frame = tk.Frame(self) tk.Label(frame, text=text).pack() self.frames.append(frame) def next_frame(self): self.frames[self.active_frame].pack_forget() self.active_frame = (self.active_frame + 1) % len(self.frames) self.frames[self.active_frame].pack() if name == "main": App().mainloop()

This optiontoolStripMenuItem1.DoubleClickEnabled = true;You need to know when there's an extinguishing menu, for example Then the double click is appropriate and will work. toolstripmenuitem.doubleclick This event, its properties were stated above. If there's no menu falling out, there's no need for doubleing.

Yeah, that's right. data binding♪ Spring extracts the data from the request and provides you with a ready object. The use of the TLD Spring Library is the one that gives you the tigs. form:*() Not required - it simply offers a more convenient way of recording the site in View. You can write shapes on the naked HTML and @ModelAttribute I'll work exactly as well.Nothing. commandName outdated, but apparently retained for opposite compatibility if https://github.com/spring-projects/spring-framework/blob/master/spring-webmvc/src/main/java/org/springframework/web/servlet/tags/form/FormTag.java It's the same object./** * Set the name of the form attribute in the model. * <p>May be a runtime expression. * @see #setModelAttribute */ public void setCommandName(String commandName) { this.modelAttribute = commandName; } /** Get the name of the form attribute in the model. @see #getModelAttribute */ protected String getCommandName() { return this.modelAttribute; }

What you want to do is not correct and I doubt it will work, but you can try two options:1- Send the data by GET: Just add them on the form tag and they'll be sent in the same way you're trying to link it:<form method="post" action="nuevaPagina.php?<?php echo "valorI1=$valorI1&valorI2=$valorI2&valorI3=$valorI3&valorI4=$valorI4&valorI5=$valorI5"; ?>"> 2- Send the data by POST: Just add them as hidden fields and will be sent with the rest of the form:<form method="post" action="nuevaPagina.php"> <?php for($i = 1; $i <= 5; $i++) { echo "<input type=\"hidden\" name=\"valorI$i\" value=\"{$_GET['valorI' . $i]}\"> } ?> For either of the two options: <input type="submit" name="submit" value="ENVIAR">

That's right, I have an identical code working perfectly.using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private const int CS_DROPSHADOW = 0x20000; protected override CreateParams CreateParams { get { CreateParams cp = base.CreateParams; cp.ClassStyle |= CS_DROPSHADOW; return cp; } } } }

The big structural problem is that it has a responsibility that is to organize the data that are taken from the database, at least the thick of the code is that. What escapes from this responsibility is comboList.Items.Add(dr[2].ToString());.This code should be part of another object that takes care of the model and not the vision (the IU). If I was separated, I could call where I want. It is not simple to do this right, to have performance would have to use advanced mechanisms that many do not know or dominate, but it is correct.This way you're doing is the same way that many people do and in something simple goes well, but it's gambiarra, it's always been, even if almost everyone does so.If you still want to insist on the gambiarra and leave everything worse, but that works (I am explicitly not recommending to do this, but I know you will), you can parametrize this method to be able to use more generically. This if really the method does exactly what you want without changing anything. This parameter would be the comboList that you would always pass on this form or the other. You cannot use without the parameter because in this current method the comboList actually it is this.comboList and you don't want it if you're going to use it on another form.I would still have to see what to do with txtNome that has the same problem, should you parameterize it too? Probably.I have already said that calling a method of a form, and that seems to be implementation detail and so private, so making it public is already another mistake, and that all this is gross gambiarra?To speak the truth is less gambiarra copy and paste that code there in the other form. It's not that it's good, but it causes less trouble.This code has other problems and makes use of in some situations, although it is not noticeable in most of them. This pattern of reinventing connection opening was taught by someone one day and everyone went wrong.

The problem is with that line <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />. She's in the wrong file. This tag is not understood by XMLSchema of the element <configuration> the app.config( file https://docs.microsoft.com/en-us/dotnet/framework/configure-apps/file-schema/configuration-element )This change you want to make(strengthen use with the administrative logon) should be made in the assembly(app.manifest) manifest file( https://docs.microsoft.com/pt-br/dotnet/framework/app-domains/assembly-manifest ).First you have to add a manifest file to your project:Right click on your project within Solution Explorer.In the context menu select "Add New Item".In the dialog box that will appear choose "File of "Application Manifest File" if you are in English.Go back to Solution Explorer and open the newly created manifest and search and modify the tags: <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2"> <security> <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">  <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />  </requestedPrivileges> </security> </trustInfo> Probably inside the manifest will be commented all requestedExecutionLevel possible:<requestedExecutionLevel level="asInvoker" uiAccess="false" /> <requestedExecutionLevel level="requireAdministrator" uiAccess="false" /> <requestedExecutionLevel level="highestAvailable" uiAccess="false" />

Table consisting of textboxIf there are several columns in the table, the dataGridView can be used in WinForms, which can define the type of ejectable cells.For example, in the cells, textBox should use DataGridViewTextBoxColumn.class Data { public string Value { get; set; } } var f = new Form(); var g = new DataGridView() { Parent = f, Dock = DockStyle.Fill, AutoGenerateColumns = false, AllowUserToAddRows = false, AllowUserToDeleteRows = false }; g.Columns.Add(new DataGridViewTextBoxColumn() { HeaderText = "value", DataPropertyName="Value" }); var l = new BindingList<Data>(); for (var i = 0; i < 5; i++) l.Add(new Data() { Value = "v"+i }); g.DataSource = l; f.ShowDialog(); Data.Value values are published in DataGridView and can be edited and changes transferred back to Data.Value.If a column is to be added, Data should add a characteristic and add another column to DataGridView.Columns.

Usually, the task of "checking what's been added," is to make a request for MAX(id) verification and to check the old meaning with the new one.If you need to check that something has changed, you create a field in the database for each updated recording_at, you put an index on it (for productivity), every n-time you check the necessary tables with a request. SELECT MAX(updated_at) FROM tableand if it's different from the old one, you do your thing. You can, for example, show what records have changed, just taking all the records of where updated_at More specific. Field updated_at It is also possible to use, as in the case of id, unless a new record is added or edited. It's just enough to fill it in on the tape, not just the update.This request will work very quickly with the index design, but if there is a lot of such requests, it's probably better to give it through the API, which would have the results for a while.In general, this is the same. Simple and adequate architectural solutionsome people create TRIGGER for the updating of the tables, and if the table is updated, the date of date of the last update and checks it from the past, someone checks the reference amount from the table or the file.

As far as I understand, I'll give you an answer. You've got ajax. As blocks<div class='goods-card' data-new='1' data-price='111' data-Alfavit='Заголовок'> <h1>Заголовок</h1> <p>111</p> <div class='col text-center'> <a href='#' class='btn btn-lg btn-success buy' data-toggle='modal' data-target='#basicModal'>Купить</a> </div> </div> On the button Купить You're going to transmit the data. This can be done in several ways. The simplest thing is to give a temporary attachment to the block when it comes to the link.$(document).on('click','a.buy',()=>{ $(this).closest('div.goods-card').addClass('current'); }); Now, when the reference is applied, the class will be added. current The block on which the reference is made, and in the open fashion window, you can take any data through this cluster. For example, the data attributes of the unit:let id = $('div.current').data('new'); //получаем data-new let price = $('div.current').data('price'); //получаем data-prive let title = $('div.current').data('Alfavit'); //получаем data-Alfavit Come on!Because when we pressed, we added the class to the current block, we have to clean it up. The best option would be to clean it up by closing the module. Bootstrap has events for these purposes. For example, hide.bs.modal - The event works before the window is closed.$('#basicModal').on('hide.bs.modal',()=>{ $('div.goods-card').removeClass('current'); });

It's a comparison of train speeds by running without pants on the roof of the electrician with thermometer in hand.The only way to deal with the controllers is in a goose flow. Since this is the only thing you're doing, you're measuring the speed of the service code, which is not part of the direct purpose of the program: flux-shifting, counterfeiting, profiling of the quind messages, garbage generation, etc.There's no multiplicity in your code, there's no parallel. It's just that in the second case, you're jumping between a goose stream and a left stream. If you're watching a significant difference, you're doing something wrong. In this case, 100,000 updates the status of the progress bar, although it is sufficient to do so 1,000 times less. If you keep up 100 times, the difference will be about zero if your method is PerformStep Do something.Parallelity begins when you begin PerformStep Parts in different flows will be performed.

You can create an event so that when you mark an item you mark the previous items; private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e) { if (e.CurrentValue != CheckState.Checked) { for (int i = e.Index - 1; i >= 0 ; i--) { checkedListBox1.SetItemChecked(i, true); } } }
