>Hi John,
>>I have a search form that allows my users to search for record by entering in their search criteria in one to six textboxes, but the way I build my select statment based on their criteria does not allow for single quotes to be used as searching criteria (my select will bomb). *SNIP*
>Have you considered reworking your select builder to use '[' instead of "'"?
>As someone else has already pointed out "'" may be part of a valid search request, for example "Dan's House of Cards".

>>First, what is the best practice in dealing with this? Should I allow the single quote and then display the message, or should I just not allow it in the first place? Is there a standardized way of dealing with this type of entry validation?

Thanks for your suggestions...The concensus seems to be to change the sql builder code to allow for single quotes and not worry about what the user types in...I agree.

Thanks.

John.
