How to Return Values to AppleScript from FoxPro

MORE INFORMATION

In the following example, the AppleScript portion asks the user for a Customer ID and then calls a Visual FoxPro program. The Visual FoxPro program then opens a database, sums the order amounts for the Customer ID that was entered, and returns the sum to the script. Then the script displays the result in a dialog box.

1. Save the following FoxPro program file as MyQuery.prg in the Visual FoxPro folder:

     PARAMETERS lcCustID
      SET DEFAULT TO HOME()+"Samples:Data"
      OPEN DATA TestData.DBC
      SELECT SUM(Order_Amt) AS Tot_Ord_Amt ;
         FROM Orders ;
         WHERE Cust_Id=UPPER(lcCustID) ;
         INTO CURSOR Temp
      SET DEFAULT TO HOME()
      IF _TALLY > 0   && Check to see that any records where found
         RETURN Temp.Tot_Ord_Amt
      ELSE
         RETURN _TALLY
      ENDIF
   						

2. Use the AppleScript Script Editor to save and run the following script.
   
   IMPORTANT: When typing the code listed below, replace the semicolons with the AppleScript line continuation character by typing Option+Enter in the Script Editor.

      copy (display dialog "Please enter the Customer's ID" buttons ;
         {"OK", "Cancel"} default answer "") to dialogResults
   
      if the button returned of dialogResults is "OK" and ;
         {the text returned of dialogResults} is not "" then
   
         tell application ;
            "Macintosh HD:Microsoft Visual FoxPro:Microsoft Visual FoxPro"
   
               activate
               Do Script "SET DEFAULT TO HOME()"
               Do Script ;
                  "myquery(["&{the text returned of dialogResults}&"])"
               display dialog the result
   
         end tell
   
      end if
