How do I return yes or no from a message box that I made?

I made a message box, a form that has a label for a message and a label for the title.

And an OK button (do nothing).

I can rise this message box f开发者_运维问答rom any form in my program.

I need a message box that has a Yes button and No button, and to know if it pressed Yes or No, how do I do it?

What would sample code for this be?

From MSDN MessageBox.Show(...):

// Initializes the variables to pass to the MessageBox.Show method.

string message = "You did not enter a server name. Cancel this operation?";
string caption = "Error Detected in Input";
MessageBoxButtons buttons = MessageBoxButtons.YesNo;
DialogResult result;

// Displays the MessageBox.

result = MessageBox.Show(message, caption, buttons);

if (result == System.Windows.Forms.DialogResult.Yes)
{
    // Closes the parent form.
    this.Close();
}

In your button's click event handler use

this.DialogResult = System.Windows.Forms.DialogResult.Yes;

instead of

this.Close();

And then handle it as normal in your calling code.

Use:

dialogResult dr;
dr = MessageBox.show("Do you want to save the record", "Confirm", MessageBoxButtons.YesNo);
if (dr == DialogResult.yes)
{
    //Code for inserting the data into the database
    messageBox.show("Record saved successfully");
}

This code is for if you want to save the form data to the database after confirmation. Here I only show how to access the value of a message box where the user presses which button.

If you want to return different kinds of results (like, say, a string of text) you can do something like this:

public class MyMessageBox : Form
{
    // You can add parameters here if needed
    public static string Ask()
    {
        var form = new MyMessageBox();
        form.ShowDialog();
        return form.ResponseTextBox.Text;
    }
    // regular stuff
}

Then just do

string answer = MyMessageBox.Ask();

If running on Windows Vista or later, you can use the Windows API Code Pack to use the new TaskDialog.

MessageBox.Show has the following method signature:

public static DialogResult Show(
    string text,
    string caption,
    MessageBoxButtons buttons
)

Which means you can specify what buttons you would like to display.

Example

var dialogResult = MessageBox.Show("Do you have socks?", "Question.", MessageBoxButtons.YesNo);

These are the following MessageBoxButtons you can select from:

• OK
• OKCancel
• AbortRetryIgnore
• YesNoCancel
• YesNo
• RetryCancel

---

There is a built-in function to do this:

var result = MessageBox.Show("your message here", "title", MessageBoxButtons.YesNo);
if (result == DialogResult.Yes) {
    // .. 
}

If you want to do similar, but with your own custom form, just set the "Yes" button's DialogResult to Yes and the "No" button's to No, and then call ShowDialog() on your form.
