Chr$(34) is the double quote
Chr$(39) is the single

is this what you're asking for?

"UPDATE Invoice SET LaborDescription = (" + Chr(34) + tempText + Chr(34) + ") WHERE InvoiceNumber = invoicenumber"

invoicenumber = key
tempText = textbox contents

I need to avoid errors due to double qoutes in the text box.  How do I go about this?

Chage your Statement like below.

"UPDATE Invoice SET LaborDescription = """ & Replace(tempText, """", """ & chr(34) & """) & """ WHERE InvoiceNumber = invoicenumber"

Good Luck!

You don't have to change it to the ascii-code. Just replace ' by ''. This can be done by the easy statement replace

for example:
sql = "UPDATE Invoice SET LaborDescription = " & Replace(tempText, "'", "''") & "WHERE InvoiceNumber = " & invoicenumber

Chr$(34) is the double quote
Chr$(39) is the single

paste this code in vb module
Function QTrim(VVariant As Variant) As Variant
QTrim = Replace(Trim(VVariant), "'", "''")
End Function

'General sql statement using the Qtrim()
sql = "UPDATE Invoice SET LaborDescription = '" & Qtrim(Text1.text) & "' WHERE InvoiceNumber = " & invoicenumber

so every time you want to replace the ' to '' just use the qtrim(value) to do it.

easy and save time during the developing

This was the only answer that used double qoutes as I asked.

Could you show me how to use a function like that but for double qoutes? Simply replacing the single with double doesn't work.
