9. Dates

10. Dates Dim myDate As Date = "11/14/2002“ Year = myDate.Year MyDate
Month = myDate.Month
Day = myDate.Day
DOW = myDate.DayOfWeek
DOY = myDate.DayOfYear
...
MyDate
Year
2002
Month 11
Day 14
Week 45
....
...

11. A TimeSpan represents the elapsed time between two dates.
Dim myDate1 As Date
Dim myDate2 As Date
Dim myTS As TimeSpan
myDate1 = Range("A1").Value
myDate2 = Range("A2").Value
myTS = myDate2 - myDate1
Range("A3").Value = myTS.Days
Date1
Date2
TIMESPAN

12. TimeSpan mySpan.Days gives you the total number of days
mySpan.TotalDays
gives you the total number of days, plus a fraction of day based on the hours

15. Strings and Characters
Dim myString As String = “This is a sample string"
Dim myString2 As String = "s"
Dim myChar As Char = "s"c

16. Testing Numbers Dim myString As String = "#2344-234-33-3"
Dim temp As String = ""
For Each x As Char In myString
If IsNumeric(x) Then
temp = temp + x
End If
Next

17. Inserting and Removing
Dim myStr As String = "This is a sample string"
myStr = myStr.Insert(4, "xyz")
myStr = myStr.Remove(4, 3) 'starting where,how many
myStr = myStr.Replace(" is", " was")
myStr = myStr.Substring(0, 9) + “ another " myStr.Substring(10, 13) + "."

18. Finding Dim myStr As String = "This is a sample string"
Dim myPosition As Integer = 0
myPosition = myStr.IndexOf("s")

19. Total length of the result
Trimming and Padding
myLenght = myString.Length
myNewString = myString.Trim()
myNewString = myString.TrimEnd()
myNewString = myString.TrimStart()
myNewString = myString.PadLeft(50)
myNewString = myString.PadRight(20)
Total length of the result
