Title: Alarm Sound enabled/disabled per CheckBox
Post by: sts69 on March 06, 2017, 09:39:42 PM

Hello programmers,
is the following possible by code or similar?
I would like to activate / deactivate an acoustic alarm with a "CheckBox". The Alarm comes by DI Tag-address (for example, 10001).

This is certainly possible with a datasubscriber, I just do not know how :-(

Thank you for your support
Steffen

- Add a Checkbox to the form
- Add a DataSubscriber
- Set PLCAddressValue to 10001
- Double click the DataSubscriber to get back to the code
- Enter this code:

Code: [Select]

if (e.ErrorID=0) AndAlso (e.Values IsNot Nothing) AndAlso (e.Values.Count>0) then
      If CheckBox1.Checked and e.Values(0)="True" then
          Dim player as New System.Media.SoundPlayer
          player.SoundLocation = ("C:\Windows\Media\Alarm01.wav")
          player.Play()
      End If
End If


You could also modify the SoundPlayer and give it an Enabled property.

"You could also modify the SoundPlayer and give it an Enabled property."

That would be great, but how does it work?
