Question

When I click a button, I want a box to popup on the screen and display a simple message. Nothing fancy really. How would I do that?

Answer 1

System.Windows.Forms.MessageBox.Show("My message here");

Make sure the System.Windows.Forms assembly is referenced your project.

Answer 2

Just type mbox then hit tab it will give you a magic shortcut to pump up a message box.

Answer 3

In Visual Studio 2015 (community edition), System.Windows.Forms is not available and hence we can t use MessageBox.Show("text").

Use this Instead:

var Msg = new MessageDialog("Some String here", "Title of Message Box");    
await Msg.ShowAsync();

Note: Your function must be defined async to use above await Msg.ShowAsync().

Answer 4

Try this:

string text = "My text that I want to display";
MessageBox.Show(text);

Answer 5

Answer 6

Why not make use of a tooltip?

private void ShowToolTip(object sender, string message)
{
  new ToolTip().Show(message, this, Cursor.Position.X - this.Location.X, Cursor.Position.Y - this.Location.Y, 1000);
}

The code above will show message for 1000 milliseconds (1 second) where you clicked.

To call it, you can use the following in your button click event:

ShowToolTip("Hello World");
