Simple alarm Clock using Visual Basic.Net
This is tutorial is all about Simple alarm Clock using Visual Basic.Net
In this tutorial, we’re going to create a simple alarm clock. This alarm clock can be used to wake a person at a specific time. To start with this application, open visual basic and create a new project and name it as “Alarm Clock”. The application when finished, it looks like as shown below.
Next, add five labels, and name the label1 as “lblcurtime” and label2 as “lblstatus” then,set the text property of the other label as “Current Time”, “Alarm Time” and “Message”. Add a Datetimpicker, then set it into “Time” format. Then add a textbox and a Button, after this rename the textbox1 as “txtmsg” and the button1 as “btnsetalarm”. And lastly add two timer.
This time, we will add functionality to our application.
First, double click the “timer1” and add the following code:
This code will simply check if the current settings of DateTimePicker1 match the Time of the day and the time is based on your local machine. So if match, it performs the following statements.
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If TimeOfDay = DateTimePicker1.Text Then
'This will instantiate a new "voice" for this app to speak through
Dim voice = CreateObject("SAPI.spvoice")
'what the content of txtmsg will be passed to voice.speak
lblstatus.Text = "Status:Alarm is not set!"
Then, double click the “timer2” and add the following code:
This will display the current time based on the local machine.
lblcurtime.Text = TimeOfDay
Next on the “form1_load” add the following code:
Timer2.Enabled = True
And finally, on the “btnsetalarm” button add the following code:
It enables the timer1 and set the alarm clock.
Timer1.Enabled = True
lblstatus.Text = "Status:Alarm is set!"
This time you can now try testing your program by pressing “F5”.
