29.24 How do I beep the computer's speaker in a Windows Form application? |
There is no Windows Form function to beep your computer's speaker. But you can just invoke the Win32 API MessageBeep. |
| using System.Runtime.InteropServices;
|
| ...
|
|
|
| [DllImport("user32.dll")]
|
| public static extern int MessageBeep(uint n);
|
|
|
| private void button2_Click(object sender, System.EventArgs e)
|
| {
|
| MessageBeep(0x0);
|
| }
|
Another method (suggested by msauper@sauper.com on microsoft.public.dotnet.framework.windowsforms) |
|
|
| Reference the VB.NET runtime support and just use the Beep() method.
|
|
|
| The method is in:
|
|
|
| Microsoft.Visual Basic.NET Runtime
|
|
|
| The method is:
|
|
|
| Microsoft.VisualBasic.Interaction.Beep();
