Splitting a DataGrid Cell Value (Numeric) into individual numbers

I am having dificulties taking a datagrid cell value stored in the following location (datagridVNTPSorted.Item(15), irow).Value) into individual digits to reassign values for counters.

The cell in the datagrid (Listed Above) contains a number between 1 and 5624. I have 4 different counters. If the number was "2856", the counters would need to be updated as follows:

intdirectoryCountDigit1 = 2
intdirectoryCountDigit2 = 8
intdirectoryCountDigit3 = 5
intdirectoryCountDigit4 = 6

If the number in datagridVNTPSorted.Item(15), irow).Value was = "24" then the values would be as follows:

intdirectoryCountDigit1 = 0
intdirectoryCountDigit2 = 0
intdirectoryCountDigit3 = 2
intdirectoryCountDigit4 = 4

I attemped to use the Left and Right functions to return digits, but I keep on getting error messages. For Example: If the number of digits is 4, I attempted to get the correct values by doing the following:

intDirectoryCountDigit1 = Int(Left(datagridVNTPSorted.Item(15, iRow), 1))

intDirectoryCountDigit2 = Int(Right(Left(datagridVNTPSorted.Item(15, iRow), 2), 1))

intDirectoryCountDigit3 = Int(Right(Left(datagridVNTPSorted.Item(15, iRow), 3), 1))

intDirectoryCountDigit4 = Int(Right(datagridVNTPSorted.Item(15, iRow), 1))

If the total number of digits was three, the first digit would always be 0

If the total Number of Digits was 2, intDirectoryCountDigit 1 & 2 would always be 0

and so on... but I get error messages.

Any help is appreciated. Thanks

you may get errors because the data does not always have 4 digits, so the Right(x,y) does not always have a value and the left(x,y) may not be the one you want.

Why dont you try to use the numeric value of the cell instead of the substring. That way you can do an integer divition. And use the Mod operator to eliminate the higher part of the cell value for the next divition.

Code:

---

intDirectoryCountDigit1 = datagridVNTPSorted.Item(15,iRow)\1000
intDirectoryCountDigit2 = (datagridVNTPSorted.Item(15,iRow) Mod 1000)\100
intDirectoryCountDigit3 = (datagridVNTPSorted.Item(15,iRow) Mod 100)\10
intDirectoryCountDigit4 = (datagridVNTPSorted.Item(15,iRow) Mod 10

Note that the division I used is with a backslash (\), this is to discard the decimals.

Here's something a bit more general purpose:

Code:

---

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Dim number = 2856

    For Each digit In Me.GetDigitArray(number, 4)
        MessageBox.Show(digit.ToString(), number.ToString())
    Next

    number = 24

    For Each digit In Me.GetDigitArray(number, 4)
        MessageBox.Show(digit.ToString(), number.ToString())
    Next
End Sub

Private Function GetDigitArray(ByVal number As Integer, ByVal count As Integer) As Integer()
    Dim text As String = number.ToString().PadLeft(count, "0"c)
    Dim characters As Char() = text.ToCharArray()
    Dim digits As Integer() = Array.ConvertAll(characters, Function(ch) Convert.ToInt32(ch, 10))

    Return digits
End Function
