ok so i have a crosstab query with a bunch of string numbre values that need to be converted to currency im my datagrid.

so i figured id loop through the dataset and change each value. then rebind to the grid when finished.
which works until i have to return the value back to the dataset. where it promptly craps out.


Public Function addDollarSign()
        Dim intCount As Integer
        Dim x As Integer
        Dim numColumns As Integer
        Dim strCellValue As String
        Dim intRow As Integer
        Dim intColumn As Integer
        Dim index As Integer

        Dim dateArray(10) As String
        dateArray(0) = "1/1/2000"
        dateArray(1) = "11/1/2006"
        dateArray(2) = "12/1/2006"
        dateArray(3) = "1/1/2007"
        dateArray(4) = "2/1/2007"
        dateArray(5) = "3/1/2007"
        dateArray(6) = "4/1/2007"
        dateArray(7) = "5/1/2007"
        dateArray(8) = "6/1/2007"
        dateArray(9) = "7/1/2007"

        index = 0
        intRow = 1
        intColumn = 3
        x = 1
        intCount = ds2.Tables("result").Rows.Count()

        'switch column after all rows finished
        Try
            Do Until intColumn = dateArray.Length
                Do Until x = intCount
                    'get value
                    strCellValue = ds2.Tables("result").Rows(x).Item(dateArray(index))
                    'add $ to value if not = 0
                    If strCellValue <> "0" Then
                        strCellValue = FormatCurrency(strCellValue, 2)
                        'return value
               ds2.Tables("result").Rows(x).Item(dateArray(index)) = strCellValue '<--errors out
                    End If
                Loop
                intRow = intRow + 1
                index = index + 1
            Loop
            intColumn = intColumn + 1
        Catch ex As Exception
            MsgBox(ex.Message)
            Debug.WriteLine(ex.Message)
            Exit Function
        End Try
    End Function

here is the error that is produced

System.FormatException: Input string was not in a correct format.
   at System.Number.ParseDouble(String s, NumberStyles style, NumberFormatInfo info)
   at System.Double.Parse(String s, NumberStyles style, IFormatProvider provider)
   at System.Convert.ToDouble(String value, IFormatProvider provider)
   at System.String.System.IConvertible.ToDouble(IFormatProvider provider)
   at System.Convert.ToDouble(Object value)
   at System.Data.Common.DoubleStorage.Set(Int32 record, Object value)
   at System.Data.DataColumn.set_Item(Int32 record, Object value)Couldn't store <$29,324.00> in 1/1/2000 Column.  Expected type is Double.

so basically it wants a double but if i used double i obviously lose the currency format. and a custom grid style/format is out of the question.

so what do i need to do to get thses values back into the dataset please help.

In your code line

strCellValue = ds2.Tables("result").Rows(x).Item(dateArray(index))

dateArray always will return date value from your array

it should either field index number or field name.

strCellValue = ds2.Tables("result").Rows(x).Item(0)

OR

strCellValue = ds2.Tables("result").Rows(x).Item("MyDate")

the reason i went with the array is bc its a cross table query with the "date value" is actually the column name. the code works properly and isnt the problem

im having a problem at this line
ds2.Tables("result").Rows(x).Item(dateArray(index)) = strCellValue

where strCellValue would contain "$29,565,123"
and its trying to insert it as a double when it needs to be string

i basically need to force the dataset to accept it as a string and not double and i dont know how to accomplish that.

Your error saying it is expecting a double value , not string. Since your value contains both comma and $ sign, it wont allow you. So you are going to lose format also.

If you are just trying to show as format , then why dont take from database as formatted.

like

select '$' + convert(varchar(10),cast(100 as money))

then you can just need to set datasource as it is.

I dont know why you are going with this approach.

ok for the win, can someone put that convert statement into this>?
i cant get it to work.

TRANSFORM Sum(dollars_import.DollarAmt) AS SumOfDollarAmt
SELECT dollars_import.projectName AS Project, dollars_import.InvType AS [Inventory Type], Sum(dollars_import.DollarAmt) AS Total
FROM dollars_import, tblProgram
GROUP BY dollars_import.projectName, dollars_import.InvType
ORDER BY dollars_import.Date
PIVOT dollars_import.Date;


dollarAmt is the field that needs conversion
