How to access an Access MDB Database from Microsoft Dynamics AX 2009

You can use the following code :


static void ConnectToAccess(Args _args)
{
//Declare connection object
CCADOConnection cn = new CCADOConnection();
CCADOCommand command = new CCADOCommand();
CCADORecordset rs = new CCADORecordset();
str Name;
;
//open connection and execute SQL command
cn.open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Sample.mdb;Persist Security Info=False");
command.activeConnection(cn);
command.commandText("SELECT * FROM DEPARTMENTS");
rs = command.execute();


while (!rs.EOF())
{
info(Strfmt("%1",rs.fields().itemIdx(1).value())); //will display query value
rs.recordSet().moveNext();
}
cn.close();

}

Authorization Checks Code

Authorization Checks
Microsoft Dynamics AX 2009 performs automatic authorization when a user
accesses data through data sources on forms or reports. X++ code can also call
these checks in cases where automatic authorization does not occur.


if (hasSecurityKeyAccess(securitykeyNum(mySecurityKey),
AccessType::View))
{
//code requiring authorization goes here...
}
if (hasMenuItemAccess(menuItemDisplayStr(myMenuItem),
MenuItemType::Display)))
{
//code requiring authorization goes here...
}
DictTable dictTable = new DictTable(tablenum(myTable));
if (dictTable.rights >= AccessType::Insert))
{
//code requiring authorization goes here...
}
if
(isConfigurationkeyEnabled(configurationkeyNum(myConfigKey)
)
{
//code requiring authorization goes here...
}
