Advice on Learning how to use Flex Data Services

Hi. I've been using flex for a while and I'm now at the stage
where I'd like to be able to develop AIR apps. I wanted to do
something simple to start with...eg. have an AIR app on a few
friends desktops that lets users tick a box if they can make it to
a poker game. Do I need to learn another language like PHP to do
this or can it be done using just Flex? Other than the live docs
and dev guide that come with flex are there other
documentation/online info that can be recommended.
Thanks!

the LCDS sql assembler might be a good fit for you. it allows
you to do sql crud from flex. there's not server side coding, just
xml config.

How to install Flex Data Services 2 on Coldfusion MX 7?

hello,
How to install Flex Data Services 2 on Coldfusion MX 7?
was is tomcat..
I want to use RemoteObject(CFC) for oracle.
Thanks for your support.

Hello -
To use mx:RemoteObject with CFC you don't even need FDS, you
can use FlexBuilder 2.0 and use it's internal FDS SDK to build,
compile and deploy full apps to be used in conjunction with CF 7.02
(Flex Connectivity)
Secondly, if you do want to install the full FDS 2.0
enterprise software you can find the instructions to do so for J2EE
apps servers here

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!

Learn how to use Powershell with AD, Exchange and Excel

Hi.
I want to learn how to script in Powershell to make my life easier at work.
Now, I'm creating Distribution Lists with cmdlets, and other simple moves, but I'd like understand and use scripts with Excel to make it easier in AD and Exchange.
Can anyone help me find out where I can learn Powershell with those tools? I've searched google and youtube, and bought books, but I'd like to learn especially about AD and Exchange through Excel.
I also have another question, I'm trying to collect the telephonenumbers in one OU in AD, and found this cmdlet:
Get-AdUser -Filter * -Properties OfficePhone | FT OfficePhone,UserPrincipalName
I lined ut the OU path before -Filter, and used * -Properties Telephones Mobile to find the phonenumber in Properties-Telephones-Mobile in Active Directory. But I'm obviously doing something wrong.
Could anyone please help me?

Hi Wezcomp,
first of all, you can use Get-Help to learn how to use Cmdlets, by asking them what it is they do:
Get-Help Get-ADUser -Detailed
By Adding the -Detailed Parameter, it will explain each Parameter of Get-ADUser and what it does. Then it will show you examples on how to use the cmdlet. Very useful tool,
Get-Help, learning to use it fully ought to be your first step, as this unlocks your access all other aspects of PowerShell. With that tool in hand, you could theoretically do the rest fully autodidactically (would be frustrating though, since you'd
like to be able to do something specific right now. Don't worry, we'll gladly help anyone truly trying to learn.).
There are lots of tutorials out there that can be useful in a general way (I added my own here). But regarding Excel:
As Fausto said, CSVs are the simple most way to do this. I'd advice against delving too deep into Excel manipulation right now (lots of frustration, little immediate rewards), Csv is your friend. Notable Commands:
Import-Csv
Export-Csv
For example, if you want to create a csv list with user data in it, using your previous example, you can do this:
Get-ADUser -Filter "*" -Properties OfficePhone | Export-Csv "C:\example\users.csv" -NoTypeInformation
By the way: FT (Format-Table) is a treacherous command: It displays objects to the console, but it is a dead end where data is concerned! Only use it when you want to check something quick on the console (like whether you got the right data), before
continuing on without using a Format command.
Cheers,
Fred

Why would I need to use LiveCycle Data Services in a Flex app?

I cannot figure out what additional functionality is provided by using LiveCycle Data Services in my Flex apps. I cannot get a clear understanding of how using LiveCycle Data Services would benefit my applications. Does someone out there use LiveCycle Data Services? If so, what do you do with it in Flex?
Thanks!

- data push for publish/subscribe implementations
User has to do nothing to get updated information. You push it to their machine when new data is available, like Yahoo finance updated quotes.
- data paging
You don't want to display one million rows in your datagrid at once. Get a batch of data, if the user scrolls down, get the next batch, etc.
- server side clustering
One server does not get overloaded. High traffic sites have their large number of concurrent connections managed more efficiently.
- JMS services
JMS is a powerful technology for messaging throughout an application, and LCDS makes it much easier.
- RTMP tunneling
Allows the use of the RTMP protocol in LiveCycle Data Services applications. Makes it easier to traverse firewalls and proxies appropriately that currently prevent direct RTMP client connections to the server.

Learning how to use Layout Managers

The code that is included in this post is public code from the SUN tutorials. I am trying to learn how to use the layouts and add individual programs that were created to each component in the layouts.
This is what I am exploring:
I want to have a tabbed layout like the example TabbedPaneDemo located at http://java.sun.com/docs/books/tutorial/uiswing/examples/components/index.html#TabbedPaneDemo. Below is the code.
In one of the tabs, I want to place a button and report in it. When the button is clicked, I want the report refreshed. Eventually I will be populating an array with data. The report I want to use the example SimpleTableDemo located at http://java.sun.com/docs/books/tutorial/uiswing/examples/components/SimpleTableDemoProject/src/components/SimpleTableDemo.java. Below is the code.
From what I have learned, you can place a container inside a container. So I should be able to place the SimpleTableDemo inside the tab 4 of the TabbedPaneDemo.
If this is indeed correct, then how do I put these two things together? I am getting a little lost in all the code.
Any assistance in helping me learn how to create and use layout managers would be appreciated.

Before I did what you suggested, which I appreciate your input, I wanted to run the code first.
I tried to run the SimpleTableDemo and received the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: SimpleTableDemo (wrong name: componets/SimpleTableDemo)
at java.lang.ClassLoader.defineClass1(Native Method)
at java.security.SecureClassLoader.defineClass(Unknown Source)
at java.net.URLClassLoader...
there are several more lines but as I was typing them out I thought that maybe the code is not written to run it in the command window. The errors seem to be around the ClassLoader. Is that correct? On the SUN example page when you launch the program a Java Web Start runs. So does this mean that the code is designed to only run in WebStart?

Does anyone know if apple's one-to-one program would be a good way to learn how to use logic pro or am I better off going to school to learn audio engineering or something?

Of course going to school would be a good option, but I want to know if one-to-one is also a good way to learn how to use logic pro. Has anyone been through the one-to-one program for logic pro and can say that they learned how to use logic pro well because of it?

For sure, one to one training, if given by a tutor who is capable, will hand you the means to build up self-confidence and will therefore let you operate the hard/software in an intelligent manner, instead of going for the trial and error method which has its pro's and con's too. Once you've passed this beginners phase you will make your own decisions intelligently and then you will also start to get experience and learn even from your mistakes. Something like that in theory and the rest is up to you!

how can I build an e-mail server with java (no matter how difficult)
please, I need help, and I really apreciate your help.
thank you very much!!

I have a situation here, I need to learn how to use
java with mysql
. Can I connect to a MYSQL DB with servlets?Yes... documentation to help you connect to any database can be found at http://java.sun.com/products/jdbc. To connect to MySQL, you'll need drivers (sourceforge.net), and the specific connection URL for those drivers will be included in the documentation.
how can I build an e-mail server with java (no matter
how difficult)If you're fairly new to JSP/Servlets, you may be in over your head here, since an email server is no easy application to code. Here's a link to the source code for the JAMES project... Apache's Java email server... maybe you can find some useful information there...

How to use TRIM DATA in CFFORM?

How to use TRIM DATA in CFFORM? when data is retrieving from
DATABASE. Wanna rtrim and ltrim while spaces.

Better to trim those values after the form submission.
Once you put them into form,
user may also makes mistake by hitting space, right?
Also, by trimming all form fields after submission, you will
be sure that your DB is clean... no whitespaces on it.
Well unless someone insert data directly onto it :)

How to use same Data Type and Length for two fields

How to use same data type and length for two fields when using 'FOR ALL ENTRIES IN' in a select statement? For instance the select queries are :
SELECT bukrs gjahr belnr lifnr budat bldat zlspr dmbtr waers shkzg
FROM bsik
INTO TABLE it_bsik
WHERE bukrs = p_bukrs
AND lifnr IN s_lifnr.
IF it_bsik IS NOT INITIAL.
SELECT belnr gjahr awkey awtyp
FROM bkpf
INTO TABLE it_bkpf
FOR ALL ENTRIES IN it_bsik
WHERE belnr = it_bsik-belnr
AND gjahr = it_bsik-gjahr.
IF it_bkpf IS NOT INITIAL.
SELECT belnr gjahr lifnr xblnr
FROM rbkp
INTO TABLE it_rbkp
FOR ALL ENTRIES IN it_bkpf
WHERE belnr = it_bkpf-awkey+0(10)
AND gjahr = it_bkpf-awkey+10(4).
ENDIF.
ENDIF.
Here it gives an error in the 3rd select query that 'When you use the addition "FOR ALL ENTRIES IN itab", the fields "GJAHR" and "IT_BKPF2-AWKEY+10(4)" must have the same type and the same length.'
Kindly clarify.

append it_bkpf1.
clear it_bkpf1.
endloop.
select belnr
        gjahr
        lifnr
        xblnr
        from RBKP
        into table it_rbkp
        for all entries in it_bkpf1
        where belnr = it_bkpf1-belnr
This is just an example. Change the fields according to your requirement.
