Full Version: Multiple criteria query based on user input into a form

I want to add functionality to an existing contacts dbase that allows contacts to be classified by organization type. (bank, law firm, university, individual, etc.). Then, when the users want to communicate with a combination of groups (law firms AND universities), Iíd like them to have a nice form where they can check boxes for all the classifications they want. The button would:
. build and run the query based on the boxes checked,
2. save it as a temporary query on which a mailing labels report is based (without prompting to overwrite the old query)
3. and then preview the mailing labels.
Lname etc.
Whatís the best way to go about this? I donít know how to get started with the form. Query by Form methods Iíve found seem to only deal with one criterion. Thanks in advance, UA Gods.
(I suppose in a perfect world, Iíd also like to create permanent record that the recipient recíd this mailing; but now Iím asking too much!)
You could declare a string variable in VBA in your form, like strSQL1 that could hold the query string. For instance, the user could select all of their check boxes desired, then click a command button that generates the sql string by adding the fields checked, like:
im strBank, strLawFirm, strSQL As String
If bank = true Then
strBank = "bank"
strBank = ""
End If
If law_firm = true Then
strLawFirm = "law_firm"
strLawFirm = ""
End If
strSQL = "SELECT " & strBank & ", " & strLawFirm & " FROM ........" (and so on)
Then open your report and set the RecordSource property to strSQL
Reports!Report1.RecordSource = strSQL
This is just an idea; I did not tweak this out as I'm sure you would have to. It is merely an avenue you could take.

Thanks for the suggestion...although I'm at a loss when it comes to using functions. I think I'm leaning more toward using a Yes/No field in the lkpClass table; having the user reset it with a button that runs an update query, then user rechecks the boxes...& clicks a button that runs report based on query. Does this sound plausible?
