Writing data to a FoxPro Memo Field with ASP form

kosmoraios · #1 (**permalink**) 06-10-04, 16:37

Help is greatly appreciated. Many Karma points will be awarded.

I have an ASP form that inputs data into a FoxPro free table (dbf). The "details" field is a memo field where the user should be able to enter unlimited data. The form works great, except:

1.) when there is a line break (enter) anywhere in the field
2.) when you exceed 254 characters.

I get this error:
Microsoft OLE DB Provider for ODBC Drivers (0x80040E14)
[Microsoft][ODBC Visual FoxPro Driver]Command contains unrecognized phrase/keyword.

I understand that the ODBC driver is not swallowing my the line break correctly. In the post, the line break is: %0D%0A

How could I replace the line break with something that the ODBC driver will eat? Or is there another solution? My code is as follows:

Code:

MM_editAction = CStr(Request("URL"))
If (Request.QueryString <> "") Then
  MM_editAction = MM_editAction & "?" & Request.QueryString
End If

' boolean to abort record edit
MM_abortEdit = false

' query string to execute
MM_editQuery = ""
%>
<%
' *** Insert Record: set variables

If (CStr(Request("MM_insert")) <> "") Then

  MM_editConnection = MM_request1_STRING
  MM_editTable = "request1"
  MM_editRedirectUrl = "thanks.htm"
  MM_fieldsStr  = "UserName|value|Type|value|subject|value|DesTime|value|MaxTime|value|Priority|value|Details|value|datetime|value"
  MM_columnsStr = "from|',none,''|type|',none,''|subject|',none,''|destime|',none,''|maxtime|',none,''|priority|',none,''|details|',none,''|submitted|',none,''"
	
  ' create the MM_fields and MM_columns arrays
  MM_fields = Split(MM_fieldsStr, "|")
  MM_columns = Split(MM_columnsStr, "|")
  
  ' set the form values
  For i = LBound(MM_fields) To UBound(MM_fields) Step 2
    MM_fields(i+1) = CStr(Request.Form(MM_fields(i)))
  Next

  ' append the query string to the redirect URL
  If (MM_editRedirectUrl <> "" And Request.QueryString <> "") Then
    If (InStr(1, MM_editRedirectUrl, "?", vbTextCompare) = 0 And Request.QueryString <> "") Then
      MM_editRedirectUrl = MM_editRedirectUrl & "?" & Request.QueryString
    Else
      MM_editRedirectUrl = MM_editRedirectUrl & "&" & Request.QueryString
    End If
  End If

End If
%>
<%
' *** Insert Record: construct a sql insert statement and execute it

If (CStr(Request("MM_insert")) <> "") Then

  ' create the sql insert statement
  MM_tableValues = ""
  MM_dbValues = ""
  For i = LBound(MM_fields) To UBound(MM_fields) Step 2
    FormVal = MM_fields(i+1)
    MM_typeArray = Split(MM_columns(i+1),",")
    Delim = MM_typeArray(0)
    If (Delim = "none") Then Delim = ""
    AltVal = MM_typeArray(1)
    If (AltVal = "none") Then AltVal = ""
    EmptyVal = MM_typeArray(2)
    If (EmptyVal = "none") Then EmptyVal = ""
    If (FormVal = "") Then
      FormVal = EmptyVal
    Else
      If (AltVal <> "") Then
        FormVal = AltVal
      ElseIf (Delim = "'") Then  ' escape quotes
        FormVal = "'" & Replace(FormVal,"'","''") & "'"
      Else
        FormVal = Delim + FormVal + Delim
      End If
    End If
    If (i <> LBound(MM_fields)) Then
      MM_tableValues = MM_tableValues & ","
      MM_dbValues = MM_dbValues & ","
    End if
    MM_tableValues = MM_tableValues & MM_columns(i)
    MM_dbValues = MM_dbValues & FormVal
  Next
  MM_editQuery = "insert into " & MM_editTable & " (" & MM_tableValues & ") values (" & MM_dbValues & ")"

  If (Not MM_abortEdit) Then
    ' execute the insert
    Set MM_editCmd = Server.CreateObject("ADODB.Command")
    MM_editCmd.ActiveConnection = MM_editConnection
    MM_editCmd.CommandText = MM_editQuery
    MM_editCmd.Execute
    MM_editCmd.ActiveConnection.Close

It sounds like 254 chars is the limit on that field.. but I don't know FoxPro. It could also be the driver interfacing to the FoxPro DB. As for the line break, you could do something like this:

Code:

Dim newLineCode
Dim myString

newLineCode = "<BR>"
myString = Request.Form("myTextbox")

myString = Replace(myString, vbCRLF, newLineCode)

Then when you read it from the DB, you can swap the last two params on that Replace, and it will convert it back to a CR and LF.

Dreamweaver always makes the code more difficult to read than it should be...
