❔ Better way to open a "window" to take in text input?

As in, when you click a button, a small window appears which exists only to take in the for example a string name with a box for the user to write the name into and maybe a text block saying something like "Enter name: ". The way I normally do this is add a whole new Window to the solution and make it do that. But I would like it possible to use something like a MessageBox to accomplish the same thing...Any luck?

iirc there is no messagebox that has a text input field. You could very easily design your own thou, and make some convenience methods on it to more or less get that behaviour MyInputBox.ShowDialog(out var name); for example.

Mmm, ok I'll do it that way... Btw do you know any way in visual studio to create a "subsidiary" window? As in to add this input window underneath the window that calls it and gets the data? Just so it's nicely organized

Im not sure what you mean by that.

if (InputDialog.ShowDialog("Username:", out var username) == DialogResult.OK)
{
    label3.Text = username;
}

if (InputDialog.ShowDialog("Username:", out var username) == DialogResult.OK)
{
    label3.Text = username;
}

public partial class InputDialog : Form
{
    public InputDialog()
    {
        InitializeComponent();
    }

    public static DialogResult ShowDialog(string prompt, out string value)
    {
        var x = new InputDialog();
        x.label2.Text = prompt;

        var result = x.ShowDialog();

        value = x.textBox1.Text;

        return result;
    }
}

public partial class InputDialog : Form
{
    public InputDialog()
    {
        InitializeComponent();
    }

    public static DialogResult ShowDialog(string prompt, out string value)
    {
        var x = new InputDialog();
        x.label2.Text = prompt;

        var result = x.ShowDialog();

        value = x.textBox1.Text;

        return result;
    }
}

extremely simple, but works

there's still the old InputBox https://learn.microsoft.com/en-us/dotnet/api/microsoft.visualbasic.interaction.inputbox?view=net-7.0 BUT you could eventually just create a little form in the code without having it in the project it would be probably just a half page method, at most a page

Interaction.InputBox(String, String, String, Int32, Int32) Method (...

Displays a prompt in a dialog box, waits for the user to input text or click a button, and then returns a string containing the contents of the text box.

Sorry for the delayed response, can you explain what is happening here? I haven't worked with windows forms yet Visual studio doesnt know about anything named Forms which you are inheriting there from... and yes, I have written using System.Windows.Forms Hey guys, I've been googling around and it seems like this "page" feature that WPF has may work well for these purposes...Thoughts?

Ah I assumed winforms since you didn't specify

GipperOP•2y ago

I mean, it has the WPF tag at the top...

Fair. It's a shame they are so easy to miss but to stay on topic, while you probably could use a Page it may not be what you want. If you think of a webpage, its more like going to "About us" more than its opening a modal with a textbox.

https://learn.microsoft.com/en-us/dotnet/desktop/wpf/windows/dialog-boxes-overview?view=netdesktop-7.0 seems to be what you want
