What is DateTimePicker Control in VB.net?
In Windows Forms, the DateTimePicker Control in VB.net lets the user choose or show date and time values in a certain format.
Using the VB.net DateTimePicker Control’s Value property, we can also find out what the current date and time are.
By default, the Value property of the DateTimePicker gives back the current date and time.
Let’s create a DateTimePicker in VB.net by dragging a DateTimePicker Control from the Toolbox and dropping it on the form.

Let’s create a program of DateTimePicker Control in the VB.NET Form.
Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
DateTimePicker1.Format = DateTimePickerFormat.Long
End Sub
Private Sub Button1_Click_3(sender As Object, e As EventArgs) Handles Button1.Click
Dim dp As Date = DateTimePicker1.Value
Dim dp2 As Date = DateTimePicker2.Value
Dim result As TimeSpan = dp2.Subtract(dp)
Dim ds As Integer = result.TotalDays
TextBox1.Text = ds
TextBox1.ForeColor = ForeColor.Red
MsgBox(" Days = " & ds)
End Sub
End Class
Program Output:
Now, we select the Hired Date and End Date from the DateTimePicker Control.
After selecting the Hired Date and the End Date from the DateTimePicker Control, click on the Calculate button, and it shows the following result.
