VB.NET DateTimePicker Control

The DateTimePicker control allows the user to select or display date and time values with a specified format in Windows Forms. Furthermore, we can determine the current date and time using the Value property of the DateTimePicker control. By default, the Value property returns the current date and time in the DateTimePicker.

Let's create a DateTimePicker control in the VB.NET Windows form using the following steps.

Step 1: The first step is to drag the DateTimePicker control from the toolbox and drop it on to the form.

Step 2: Once the DateTimePicker is added to the form, we can set various properties of the DateTimePicker by clicking on the DateTimePicker control.

Note: The MinDate and MaxDate property of the DateTimePicker control allows the user to set the limits on the date range.

Let's create a program of DateTimePicker control in the VB.NET form.

DateTime.vb

Public Class DateTime
    Private Sub DateTime_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Me.Text = "javatpoint.com"
        Button1.Text = "Calculate Days"
        Label1.Text = "Calculate the total days from your date of birth to the current date."
        Label2.Text = "Total Days"
        Label3.Text = "Select the DOB"
        Label4.Text = "Current Date"
        DateTimePicker1.Format = DateTimePickerFormat.Long
    End Sub
    Private Sub Button1_Click(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 = dp.Subtract(dp2)
        Dim ds As Integer = result.TotalDays
        TextBox1.Text = ds
        TextBox1.ForeColor = ForeColor.Red
        MsgBox(" Days = " & ds)
    End Sub
End Class

Output:

Now, we select the date of birth from the DateTimePicker Control.

After selecting the DOB and the Current date from the DateTimePicker Control, now click on the Calculate button, and it shows the following result.
