[Solved] vb.net timeadding from two textbox

by


  1. Split the strings in the TextBoxes into an array. The first element will contain the hours and the second element will contain the minutes. The c following the split character tells the compiler this is a char not a string.
  2. Use the constructor of the TimeSpan structure to create TimeSpans. The constructor takes 3 arguments, Hours as Integer, Minutes as Integer and Seconds as Integer.
  3. Finally, we can do the addition.
  4. Then display the result using .ToString with a format string. The \ is and escape character so it doesn’t think the : is something else.
 Private Sub GetTotalTime()
            Dim parseTime1() As String = TxtDTEAP.Text.Split(":"c)
            Dim parseTime2() As String = TxtWTEAP.Text.Split(":"c)
            Dim dt As TimeSpan = New TimeSpan(CInt(parseTime1(0)), CInt(parseTime1(1)), 0)
            Dim wt As TimeSpan = New TimeSpan(CInt(parseTime2(0)), CInt(parseTime2(1)), 0)
            Dim result As TimeSpan = dt + wt
            TxtTRTEAP.Text = result.ToString("h\:mm")
    End Sub
