"Add 5 minutes to current time which is in string"

[sonyayasr]

Hi, I have taken two textboxes, 1 shows the current time i.e system time, while in other textbox, I want to show five minutes added to the system time. How to do that?

Private Sub Arrival_timeTextBox_TextChanged(sender As Object, e As EventArgs) Handles Arrival_timeTextBox.TextChanged

        Arrival_timeTextBox.Text = DateTime.Now.ToLongTimeString()
    End Sub

    Private Sub DepartureTextBox_TextChanged(sender As Object, e As EventArgs) Handles DepartureTextBox.TextChanged

??

    End Sub
End Class

Hi,

You most likely are not going to want to set the textbox`s text inside the same textbox`s TextChanged event. Depending on what you are doing it may cause an infinite loop.

You will want to use a Date variable to assign the current date to and display that in one textbox. Then you can use the Date.AddMinutes method to add 5 minutes to that date. Then display that in the other textbox.

Here is an example:

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim CurrentDate As Date = Now
        Arrival_timeTextBox.Text = CurrentDate.ToLongTimeString()

        Dim FiveMinutesAdded As Date = CurrentDate.AddMinutes(5)
        DepartureTextBox.Text = FiveMinutesAdded.ToLongTimeString
    End Sub

Use one of the DateTime.TryPar se methods to retrieve the date out of the text box and convert it into a DateTime type.

Once you have converted/parsed the string into a DateTime type you can use the methods like the AddMinutes Method to do what you want.
