Charts in Web VI not using current data - lag, delayed

Hi, I'm using Labview to generate a "web portal" for viewing some realtime information coming from a number of machines.
The machines report power system frequency from a number of sites and display the current measurement as an ASCII readout on the Labview front panel, but I also have a chart showing the history of the measurements over the last 20 seconds. When I look at the front panel on the computer hosting the VI (i.e. on its monitor) all is well and all the data is correct, current and up-to-date.
However, when I access via the web interface (using an Embedded VI) the ASCII readouts are all current, however, the chart is delayed by a variable amount. I have seen it chart data 3 seconds behind the current samples, and sometimes nearly a minute behind. i.e., the timestamp of the most recent value on the web chart is lagging the most recent time stamp at the server, even though the web interface is getting the most recent values on the ASCII readouts.
I'm guessing there is some sort of error in rendering the charts at the web client Labview Runtime Engine, but I've no idea how I might fix this. Any advice would be much appreciated.
I am using Labview 7.1 for historical reasons, I can upgrade to 8.6, but would prefer not to.
Thanks

It is a good amount of time ago that I have been using remote panels with LabVIEW 7.0 but I have faced the same issue in 2003 (if I remember correctly). As far as I remember, the big difference between updating a numeric indicator and a chart is, that updating the chart requires the entire history needs to be send to the remote client.
You say "I also have a chart showing the history of the measurements over the last 20 seconds". I think that you expect too much from the remote panel in conjunction with charts. If you write to the chart at a slower rate you might get better behaviour.
Another apprach (I do not remember if this is a good tip): The behaviour might improve by decreasing the Chart History Length.
Hope this helps, Guenter

Current date parameter in concurrent program is not not taking current date

Hi All,
I have scheduled one concurrent request running very day @21:30 ,one of the parameter passed is current date ,which defined as default value at the time of defining concurrent program.Surprisingly its taking next day date as parameter.Can someone help me resolving this issue.
From where this current date is taken.
When I am logged in unix as oracle user and executing following query I am getting follwoing results
SQL> alter session set nls_date_format='MM/DD/YYYY HH24:MI:SS';
Session altered.
SQL> select current_date from dual;
CURRENT_DATE
05/25/2010 07:40:11
SQL> select sysdate from dual;
SYSDATE
05/25/2010 07:40:20
date
Tue May 25 07:40:35 SAUST 2010
When I logged in unix as applmgr user:
SQL> select current_date from dual;
CURRENT_DATE

SQL> select sysdate from dual;
SYSDATE
05/25/2010 07:41:19
date
Tue May 25 07:41:04 SAUST 2010
Unix level date is correct and sysdate is also correct in both cases.
But current_date when logged in s applmgr user is wrong,is this reason for the issue.
If so how can I change it
Version : 11.5.10.2
Database : 10.2.0.4
OS : AIX 5.3
Thanks in advance

Populate ComboBox from database - NOT using Flex Data Services

Hi there,
We are using CF with Flex but are not using the Flex Data
Service. I'm very much a newb and I'm having trouble finding any
information on how to populate controles from a database without
using Flex Data Service. Any help would be greatly appreciated.
First I have a page... JobSearch.mxml that contains a combo
box that I want to populate with the job_id and job_title from a
MSSQL database.
In Flex in the RDS DataView I used the "Create CFC" Wizard
which generated "job.cfc" and "jobGateway.cfc". It also generated
"job.as".
The CF Function that selects the data appears to be defaulted
and called "load" and the .as function is called simply "job".
So, that all looks great. But I can't find any information on
what I need to have on my JobSearch.mxml to actually get this data
into the comboBox.
I did:
<mx:Script>
<![CDATA[
[Bindable]
public var jobData:job = null;
]]>
</mx:Script>
And then:
<mx:ComboBox
text="{jobData.job_title}"></mx:ComboBox>
But I'm being told "Type was not found or was not a
complie-time constant: job"
I guess I'm missing something, or doing something way
wrong... I just don't know enough of Flex at this point to know
what it is.
Thanks!

Using php or asp is not an option, as we are a Cold Fusion
House.
I was looking at an article on Ben Forta's blog (
http://www.forta.com/blog/index.cfm?mode=e&entry=1786)
and following his example I did this... only it doesn't work:
I'm very very new to Flash and we are using ColdFusion but
are not using Flex Data Services. I've been trying to figure out
how to populate a combobox from a database and I'm just not having
any luck.
My project is called "PreTraffic". I have my main file as
"JobSearch.mxml" and a folder under the root named "cfc" with a
file called "job.cfc".
job.cfc contains the following code:
<cfcomponent>

<cffunction name="GetJob" access="remote"
returntype="query" output="false">
<cfset var job="">
<cfset var results="">
<cfquery datasource="discsdev" name="job">
SELECT job_id, job_title
FROM job
WHERE status = 'O'
ORDER BY job_title
</cfquery>
<cfquery dbtype="query" name="results">
SELECT job_title AS label, job_id AS data
FROM job
ORDER BY label
</cfquery>
<cfreturn results>
</cffunction>
</cfcomponent>
And JobSearch.mxml has the following code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx="
http://www.adobe.com/2006/mxml"
xmlns="*"
layout="absolute"
backgroundGradientColors="[#ffffff, #d0d0d0]"
creationComplete="InitApp()">
<mx:Style source="style.css" />
<mx:Script>
<![CDATA[
public function InitApp():void {
jobSvc.GetJob();
]]>
</mx:Script>

<mx:RemoteObject id="jobSvc" destination="PreTraffic"
showBusyCursor="true" />
<mx:VBox label="Job History" width="100%" height="100%"
x="10" y="92">
<mx:Label text="Search jobs by"/>
<mx:Form label="Task" width="100%">
<mx:FormItem label="Job Name:">
<mx:ComboBox id="jobNameCB"
dataProvider="{jobSvc.GetJob.results}"></mx:ComboBox>
</mx:FormItem>
</mx:Form>
<mx:HBox>
<mx:Button label="Search"/>
<mx:Button label="Clear"/>
</mx:HBox>
</mx:VBox>
</mx:Application>
My Compiler thingy points to:
-services
"/Volumes/flexwwwroot/WEB-INF/flex/job-services-config.xml" -locale
en_US
and job-services-config.xml contains the following code:
<destination id="PreTraffic">
<channels>
<channel ref="my-cfamf"/>
</channels>
<properties>
<source>flex.pretraffic.cfc.job</source>
<lowercase-keys>true</lowercase-keys>
</properties>
</destination>
Well, when I run the app... the combobox is not populated...
Can anyone help with what I've done wrong?
Thanks!

Any ideas greatly appreciated, it will save me a journey to the apple store

I have now solved it. I signed out of my iTunes account and then held down both the power buttons until the apple appeared. When I signed back in it started downloading.

When you double click the circle buttom, and the little bar pops up from what you have been using... is it using data while being in there? is it a good idea to minimize evertthing out of there often so its not using more data ? or does it not matter?

Not sure if it uses data, but that allows you to multitask. To save battery life you should close out of all the apps.

Webi does not pick correct Data

Hi Guys,
I have a webi. The Universe for the Webi is based on Bex Query. I see correct Data in Bex Query but when I create a webi report it does not pick correct data.
I have checked following points already:-
1] No Resstriction at Query Level
2] No restriction at Universe Level
3] No Filters/ Restriction at Webi Level.
Can anyone suggest whats happening?
Regards

Hi Ray,
It happens sometimes that data gets aggregated over all the dimension objects present in the 'Available Objects' section in webi.
Try to pull only the characteristics present in the row section of the bex query say 'X' and measure in the column section of bex query say 'Y' into the results pane in the edit query window in webi.Then run the report and check.
This will give you the idea about aggregation.

Running BW Query in a Web, but not using Portal

Is it possible to use iMessage only over WiFi, and not use cellular data?

When I go to Settings -> Cellular, there is no toggle for messages. Is there some way I could selectively disable cellular data usage for messages? That is, I want messages to be sent with SMS instead of data even if cellular data is available, but not if WiFi is available. If WiFi is available, then I would want the message to use the WiFi.
My situation is that I will be traveling internationally and will have a plan that allows unlimited texting but limited data. I don't want to have to toggle iMessage on and off every time I connect to WiFi to prevent data use with messages!
Thanks for any help!

The only option you have is to turn off cellular data completely. You are correct, there is no setting for cellular data for messages. If you toggle iMessage off/on multiple times, you will end up with problems, since others will not know if you have iMessage off/on, and will continue to try to send iMessages to you. Also, you may find you will have problems with iMessage activating again after turning it off. iMessages do not use very much data, but if you are using data for other reasons, that could use up the limited pool of data you mentioned

Delivery date mandatory and not defulted current date

Hi all,
I want to make the delivery date mandatory in the purchase Requisition and currently the current date is defaulted there , i want that nothing should be there initially.
Please provide the configuration setting.
Regards,
Kapil.

Hi,
U can make the delivery date field as mandatory in PR , by setting delivery date field as required entry in PR sscreen layout in customization.
Go to SPRO- MM - Purchasing - PR- Define screen layout at doc level - ME51N - Deadline monitoring - Delivery date ( Make this field as reqd entry ) and save it.
And regarding ur second question the default date should be blank, the date gets calculated here based on the planned del time maintained in materila master in MRP2 view.
So if the date showing is todays date when u r creating PR today means, the planned delivery time maintained in MMR is zero days.

Leopard update ical dock not keeping current date

since the update last week, the dock icon has stopped keeping the current date. the first day I noticed it stopped updating I did a kill dock. stayed on that day.
I removed it from the dock, then re-added it, keeps that date.
anyone else, is this a know issue?
thanks

go to the dock, trash the ical icon there, then go to the applications folder, and drag a fresh ical icon to the dock.
also would be a good idea to do a software update before that if your the OS in your profile is correct
hope this helps

Hi Briston,
you must somehow set time to 00:00 or cut it. this works for me:
package brano.test1.view;
import java.text.SimpleDateFormat;
import java.util.Date;
public class MyBB {
    private Date today;
    public MyBB() {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        try {
            String stringToday = sdf.format(new Date());
            today = sdf.parse(stringToday);
            System.out.println(stringToday);
        } catch (Exception e) {
    public void setToday(Date today) {
    this.today = today;
    public Date getToday() {
    return today;
}regards,
