Question

On the adobe website was this code:


var conn:SQLConnection = new SQLConnection();
var dbFile:File = File.applicationStorageDirectory.resolvePath("DBSample.db");

try
{
conn.open(dbFile);
trace("the database was created successfully");
}
catch (error:SQLError)
{
trace("Error message:", error.message);
trace("Details:", error.details);
}


on the line of


conn.open(dbFile);


there is an errorcode: 1120, Access of undefined property

Can anyone help? I just started with flex.

@aftee:
Here is the whole mx:Script, it stays also between CDATA

import flash.data.SQLConnection;
import flash.data.SQLStatement;
import flash.events.SQLErrorEvent;
import flash.events.SQLEvent;
import flash.errors.SQLError;
import flash.filesystem.File;

var conn:SQLConnection = new SQLConnection();
var dbFile:File = File.applicationStorageDirectory.resolvePath(“DBSample.db”);

try
{
conn.open(dbFile);
trace(“the database was created successfully”);
}
catch (error:SQLError)
{
trace(“Error message:”, error.message);
trace(“Details:”, error.details);
}
var createStmt:SQLStatement = new SQLStatement();
createStmt.sqlConnection = conn;
var sql:String =
“CREATE TABLE IF NOT EXISTS employees (” +
” empId INTEGER PRIMARY KEY AUTOINCREMENT, ” +
” firstName TEXT, ” +
” lastName TEXT, ” +
” salary NUMERIC CHECK (salary > 0)” +
“)”;
createStmt.text = sql;
createStmt.addEventListener(SQLEvent.RESULT, createResult);
createStmt.addEventListener(SQLErrorEvent.ERROR, createError);
createStmt.execute();
function createResult(event:SQLEvent):void
{
trace(“Table created”);
}
function createError(event:SQLErrorEvent):void
{
trace(“Error message:”, event.error.message);
trace(“Details:”, event.error.details);
}

add to the mx:application tag this option: creationComplete="init()"

and put your code to this function

private function init():void {
var conn:SQLConnection = new SQLConnection(); 
var dbFile:File = File.applicationStorageDirectory.resolvePath("DBSample.db");

conn.open(dbFile);
...
}
