I have a unbound list box on a form in Access database.  I want some values to be 3 decimal places and some to be 4, but all are rounding to two.  Some are pulling values from table and some from queries.  How can I control the # of decimal places shown on form?

You did not post many details on the listbox, other than to say it is unbound...

I don't think that you can specify that some values in a column to be 3 decimal places and others to be 4.

Or ...are you saying this this is needed for different "Columns".

If so, then set the number of decimal places in the "table" that provides these values.

You must define that number in the query that is the rowsource for your listbox

Start out by using the Round([fieldname], decimal places ) function to get the right number of decimals.

Keep in mind, that all entries in a listbox are treated as text and will be left aligned.  Another option would be to create a continuous form, which would give you the ability to align these numeric values to the right of a textbox.

...For example, in the table, set the field property: Format to "Fixed"
Then set the decimal places property as needed. (2 or 3 ,...or whatever...)
Then when you load these values into the listbox, they will have the desired decimal places.

The reason I recommended the Round( ) function was that the OP indicated some needed 3 decimals, some need 4.  Unfortunately, Access doesn't have a decimal align feature like Word and Powerpoint do.  Now, that would be a useful addition.

I was able to resolve this in the table I had created.  The Data Type is currency, but changed the format to general number and set the decimal places at what I wanted it to be.  This way allows my unbound text box to show the decimal placed I want.  
Thanks to all for your suggestions.

OK by me.

Just a note.
With a currency datatype you can set the number of decimals places as well (so there may be no need to change the datatype.

If you change the datatype from Currency you loose the default currency format (Dollar sign, thousandth separator), and you may end up having to "format" the final result as currency anyway...

My own comment was the easiest way for me to reach a conclusion.  Not saying any of the others wouldn't work, but based on my skill-set this was best approach for me.
