Database to Flash

ASP gets the data from the db and sends into Flash

Getting Data from the database into Flash

ASP gets the data from the database and sends it to your Flash interface

In this step of our Flash and ASP integration guide, ASP interacts with the database and sends the required data for display to the Flash display form. This section is divided into two parts:

  1. The ASP page interacts with the Database and gets the required data
  2. ASP sends the retrieved data to Flash

Note: Values or code you will have to enter are given in light blue. All ASP code can be directly cut and pasted into your file. Comments in ASP are in green.

ASP Gets the Data from the Database

  • Open your GuestBookGetCode.asp file. You will have to do the following steps to get data from the database.
    • Connect to the Database
    • Select the required data and get it into a recordset with a page size (the maximum no. of records you would like to load at a time).
  • Below is shown the code to accomplish these steps. Add it to the existing code in the file. You can cut and paste the code but it is good practice to understand what it does first.

Connecting to the Database and getting data from it through ASP

<% '---------------This file is the GuestBookGetCode.asp file-------------------------

'Start Declaring all variable used by you (you can do this as you blue)
Dim DBConn, strDB, rsGuestBook, x, intSize, strSelectSQL, strDate, fldName, fldEmail, fldMess, fldDate, intPage, intStart, intFinish, intCount, intPageCount, intRecord, intNav,blnSubmit

'Give the Database Connection String
strDB = "DRIVER={Microsoft Access Driver (*.mdb)};DBQ=" & Server.MapPath("dbGuestbook.mdb") & ";DefaultDir=" & Server.MapPath(".") & ";DriverId=25;FIL=MS Access;MaxBufferSize=512;PageTimeout=5"

'Get today's Date and give the number of entries you would like to load per batch

'Get the variable to determine if a submission has been made

'Get the Batch Number of the Guest-Book entries
if intNav = "" then intPage = 1 else intPage = cint(intNav)

'Give the SQL Select Statement
strSelectSQL="SELECT fldName, fldEmail, fldMessage, fldDate FROM tblGuestBook ORDER BY fldDate DESC , fldGID DESC"

'Create the Recordset with Read Only - Static (Forward and Backward Cursor) properties
Set DBConn = Server.CreateObject("ADODB.Connection")
DBConn.Open strDB
set rsGuestBook=Server.CreateObject("ADODB.Recordset")
rsGuestBook.ActiveConnection = DBConn
rsGuestBook.Source = strSelectSQL
rsGuestBook.CursorType = 3
rsGuestBook.CursorLocation = 3
rsGuestBook.LockType = 1

'The recordset is paged for optimization of the code
rsGuestBook.PageSize = intSize
rsGuestBook.CacheSize = intSize
intPageCount = rsGuestBook.PageCount
intCount = rsGuestBook.RecordCount
Set rsGuestBook.ActiveConnection = Nothing

If (not rsGuestBook.EOF) then
       rsGuestBook.AbsolutePage = intPage
       intStart = rsGuestBook.AbsolutePosition
End if

if CInt(intPage) = CInt(intPageCount) then
       intFinish = intCount
       intFinish = intStart + (rsGuestBook.PageSize - 1)
end if


ASP Send the Data to Flash

  • Now the ASP file is ready to send the Data to Flash. Remember this is done in the Variable-Value format. Add the following code to the same GuestBookGetCode.asp file as a continuation of the above.

Supplying Data to the Flash Interface by the ASP file

<% '---------------Output the Data in the 'Variable-Value' format-----------------

response.write "&size=" & intSize & "&count=" & intCount "
if intCount=0 then response.write "&f_name=No Guest Entries Yet"

'The Flash interface needs an Initial Value for displaying the first record
if not rsGuestBook.Eof then
      if blnSubmit="True" then rsGuestBook.Movenext
      if not rsGuestBook.Eof then
             set fldDate=rsGuestBook("fldDate")
             set fldName=rsGuestBook("fldName")
             set fldEmail=rsGuestBook("fldEmail")
             set fldMess=rsGuestBook("fldMessage")
             response.write "&startN=" & fldName & "&startE=" & fldEmail & "&startM=" & fldMess & "&startD=" & fldDate & "&date=" & strDate
       end if
end if

'Now output all the records, each with an identifying index, value 'x'
x = ((intPage-1)*intSize)+1

For intRecord = 1 to rsGuestBook.PageSize
       if rsGuestbook.EOF then Exit For
       response.write "&name" & x & "=" & fldName & "&email" & x & "=" & fldEmail & "&mess" & x & "=" &        fldMess & "&date" & x & "=" & fldDate
       x = x + 1

'Now close the recordset and database connection. Also set them and the fields (that were set to values from fields in the recordset) to Nothing
Set rsGuestBook = nothing
Set fldName=nothing
Set fldEmail=nothing
Set fldMess=nothing
Set DBConn = nothing


Congratulations you have finished the ASP part of sending data to Flash.
