Microsoft Access Double Click Event chokes on the apostrophe (') and quote (") symbols.

I built an Access database that stores our "Office Supplies" with several reports that when generated I can "Double-Click" a line item in that report and open it's corresponding record in a form.  I did this using a macro in the Double Click 'Event' Property.

It was giving a syntax error when it encountered any record had an apostrophe within the ItemName field.  To get around this I wrote the macro:
="[ItemName]=" & Chr(34) & [ItemName] & Chr(34)

This worked great! But I recently found out that I got the same Macro Syntax error when it encountered a quote (") symbol in the ItemName field of any record.

My question is:  How can I properly incorporate both Chr(34) AND Chr(39) strings in this Event macro?

I have tried every way I know of to And/Or it but have been failing miserably.  What is the right way to do this?

If your string might contain either single or double quotes, you have to "escape" them.  Do that with a Replace().  You'll need two of them.  One to change the  one single quote to two single quotes and the other to change the one double quote to two double quotes.  Your string will end up like:

That's two single quotes, not one double but it's hard to see.

if the data HAS what you are using to delimit in it, you can replace them with 2
="[ItemName]=" & Chr(34) & Replace( [ItemName] ,"""", """""")  & Chr(34)

Open in new window

"" inside a string delimited with " gives you just 1 " when things are done ~

I use a function:

Public Function fnQuotes(QuoteWhat as Variant, Optional QuoteWith as String = """") as String

    If IsNull(QuoteWhat) Then
        fnQuotes = "NULL"
        fnQuotes = QuoteWith & Replace(QuoteWhat, QuoteWith, QuoteWith & QuoteWith) & QuoteWith

End Function

Open in new window

You can use this with text strings, or with date literals as well

="[ItemName]=" & fnQuotes([ItemName])

or if you want to use single quotes

="[ItemName]=" & fnQuotes([ItemName] , chr$(39))

or, if you want to encapsulate dates in #:

= "[DateField] >= " & fnQuotes(dtStartDate, "#")
