My database has a [Precision] column for numeric data items. How can I use
this number in the "format" command, such that for, say precision 2, I get
numbers like 2011.01 or 2387.00 and for 4 I would get 2011.0100 or
2387.0000?
(simple question I know!)
5  2143 
Precision isn't necessarily the same as decimal places. What db is it? SQL /
Oracle / Jet?

I'm using SQL Server. I don't mean precision, I mean "displayed decimal
places". My "displayed decimal places" is a field, when its 2, I just want
to show aa.bb, when its 3, aa.bbb (or aaaaaaaaaa.bbb) etc. Sure this is
probably quite simple using "Format"?

When you say "My "displayed decimal places" is a field" what are you
displaying it in? A datagrid or a textbox? The formatting of the display
on the client has nothing to do with the database. Look at the
String.Format command if using a textbox. If you are using a datagrid there
is a format property on the DataGridTextBoxColumn object that will format
the display. The display format string you are looking for is "0.0000"
Hope it helps

Hi,
Use a numberformatinfo. This is how to get a datagrid to display 3
digits after the decimal. Place this in your tablestyle for the grid.
Dim cm As CurrencyManager = CType(Me.BindingContext(DataGrid1.DataSource),
CurrencyManager)
Dim pd As System.ComponentModel.PropertyDescriptor =
cm.GetItemProperties()("Qty")
Dim ni As New System.Globalization.NumberFormatInfo
ni.NumberDecimalDigits = 3
Dim colQty As New DataGridTextBoxColumn(pd, "f")
With colQty
..MappingName = "Col1"
..HeaderText = "Qty"
..Width = 75
..FormatInfo = ni
End With

Yes, I worked it out something like this:
Dim theStringToDisplay as String = "######." + "0".PadRight(myPrecision,
"0"c)
So I have a variable "displayed decimal places" according to the value of
the precision column in the database ( there is a column called [Precision]
(a tinyint) that tells me how many decimal places the user wants with his
value - we use this because I am sending up values to another piece of
custom hardware which requires this information).
Thanks.
