hello i'm using visual studio 2012 and sql server 2012 to make a form to export datagridview to microsoft excel 2010.

my coding for button export is like this:

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim xlApp As Microsoft.Office.Interop.Excel.Application
        Dim xlWorkBook As Microsoft.Office.Interop.Excel.Workbook
        Dim xlWorkSheet As Microsoft.Office.Interop.Excel.Worksheet
        Dim misValue As Object = System.Reflection.Missing.Value
        Dim i As Integer
        Dim j As Integer
        xlApp = New Microsoft.Office.Interop.Excel.Application
        xlWorkBook = xlApp.Workbooks.Add(misValue)
        xlWorkSheet = xlWorkBook.Sheets("sheet1")

        For i = 0 To DataGridView1.RowCount - 2
            For j = 0 To DataGridView1.ColumnCount - 1
                For k As Integer = 1 To DataGridView1.Columns.Count
                    xlWorkSheet.Cells(1, k) = DataGridView1.Columns(k - 1).HeaderText
                    xlWorkSheet.Cells(i + 2, j + 1) = DataGridView1(j, i).Value.ToString()



        MsgBox("You can find the file D:\vbexcel.xlsx")
    End Sub
    Private Sub releaseObject(ByVal obj As Object)
            obj = Nothing
        Catch ex As Exception
            obj = Nothing
        End Try
    End Sub
End Class

what i want to ask is:

- how do i make the coding to set the cell size in the microsoft excel will automatically adjust to the size of column in my datagridview?

example: in my datagridview there is a column named date of birth with value:12/09/1994.but, when i export the data to excel the value became ##### and the cell in excel doesn't adjust to the column size in the datagridview.

- how do i make the coding in the visual studio to adjust the position of the text(center,left,or right) in the microsoft excel cell?
