• global variable and Python

  - by rejinacm

  A global variable created in one function cannot be used in another function directly. Instead I need to store the global variable in a local variable of the function which needs its access. Am I correct? Why is it so?

• Cassandra use PHP SimpleCassie get all keys

  - by chnet

  Is it possible to get all keys in a column family using SimpleCassie? I looked at SimpleCassie's google code, but do not figure out. Another issue is that I used following code to access column value. $price = $cassie-keyspace('ToyStore')-cf('Toys')-key('Transformer')-column('Price')-get(); echo $price; It always complains "object of cassandra columnorsupercolumn cannot be converted to string". Is it possible to print out the column value?

• Continuous Form, how to add/update records with external connection

  - by Mohgeroth

  EDIT After some more research I found that I cannot use a continuous form with an unbound form since it can only reference a single record at a time. Given that I've altered my question... I have a sample form that pulls out data to enter into a table as an intermediary. Initially the form is unbound and I open connections to two main recordsets. I set the listbox's recordset equal to one of them and the forms recordset equal to the other. The problem is that I cannot add records or update existing ones. Attempting to key into the fields does nothing almost as if the field was locked (Which it is not). Settings of the recordsets are OpenKeyset and LockPessimistic. Tables are not linked, they come from an outside access database seperate from this project and must remain that way. I am using an adodb connection to get the data. Could the separation of the data from the project be causing this? Sample Code from the Form Option Compare Database Option Explicit Private conn As CRobbers_Connections Private exception As CError_Trapping Private mClient_Translations As ADODB.Recordset Private mUnmatched_Clients As ADODB.Recordset Private mExcluded_Clients As ADODB.Recordset //Construction Private Sub Form_Open(Cancel As Integer) Set conn = New CRobbers_Connections Set exception = New CError_Trapping Set mClient_Translations = New ADODB.Recordset Set mUnmatched_Clients = New ADODB.Recordset Set mExcluded_Clients = New ADODB.Recordset mClient_Translations.Open "SELECT * FROM Client_Translation" _ , conn.RBRS_Conn, adOpenKeyset, adLockPessimistic mUnmatched_Clients.Open "SELECT DISTINCT(a.Client) as Client" _ & " FROM Master_Projections a " _ & " WHERE Client NOT IN ( " _ & " SELECT DISTINCT ClientID " _ & " FROM Client_Translation);" _ , conn.RBRS_Conn, adOpenKeyset, adLockPessimistic mExcluded_Clients.Open "SELECT * FROM Clients_Excluded" _ , conn.RBRS_Conn, adOpenKeyset, adLockPessimistic End Sub //Add new record to the client translations Private Sub cmdAddNew_Click() If lstUnconfirmed <> "" Then AddRecord End If End Sub Private Function AddRecord() With mClient_Translations .AddNew .Fields("ClientID") = Me.lstUnconfirmed .Fields("ClientAbbr") = Me.txtTmpShort .Fields("ClientName") = Me.txtTmpLong .Update End With UpdateRecords End Function Private Function UpdateRecords() Me.lstUnconfirmed.Requery End Function //Load events (After construction) Private Sub Form_Load() Set lstUnconfirmed.Recordset = mUnmatched_Clients //Link recordset into listbox Set Me.Recordset = mClient_Translations End Sub //Destruction method Private Sub Form_Close() Set conn = Nothing Set exception = Nothing Set lstUnconfirmed.Recordset = Nothing Set Me.Recordset = Nothing Set mUnmatched_Clients = Nothing Set mExcluded_Clients = Nothing Set mClient_Translations = Nothing End Sub
