States in Flex3

Hi,
I am currently using FlexBuilder3 and am perplexed with a case that I have --
I have two Radio Button groups
If we select a button, a child datefield component is created.
First thought, I decided to handle this with States.
But the problem is that if I select anything on the second radiobutton group, the child created for the first would disappear, which is rightly so.
My brain is hurting of the thinking that I have been doing all day and I request anyone who has been through such a problem message me back with their ideas.
Thanks,
Sai

Hi.
You can set properties with transistions there you can set visible true/false and includeInLayout true/false depending witch grid you want to view.
Or you can try using the ViewStack component.

A query with respect to Flex 3 States

Hi ,
I am new to Flex3. states
I have started with a sample application , but i couldn't able to understand some of the things in Flex 3 States . Please help .
This is my sample Application what i am trying :
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
    xmlns:mx="http://www.adobe.com/2006/mxml"
    layout="absolute"
    currentState="bad">
    <mx:states>
        <mx:State name="bad">
            <mx:SetProperty target="{label1}" name="text" value="Bad Day!"/>
            <mx:SetProperty target="{linkbutton1}" name="label" value="Go Good"/>
            <mx:SetEventHandler target="{linkbutton1}" name="click" handler="this.currentState='vgood'"/>
        </mx:State>
        <mx:State name="vgood" >
                <mx:SetProperty target="{linkbutton1}" name="label" value="Go Good"/>
        </mx:State>
    </mx:states>
    <mx:Label
        x="255" y="191"
        text="Good Day !"
        fontWeight="bold"
        fontSize="22" id="label1"/>
    <mx:Button
        x="255" y="98"
        label="Go To Bad Day"
        click="this.currentState='bad'" id="linkbutton1"/>
</mx:Application>
Please see the above code , It is working fine , but i am having some questions related to it .
Please tell me whether Is it possible to know under what state the Application is currently in ??
Thnaks in advance .

Okay fine , i will do that .
I am having one more question related to flex 3 states . That is :
Refering to the above program posted , in case if i need to change the current state , i am depending on this
            <mx:SetEventHandler target="{linkbutton1}" name="click" handler="this.currentState='vgood'"/>
Is it not possible to achive the above requirement using <mx:Property>
            <mx:SetProperty target="{linkbutton1}" name="label" value="Go Good" handler="this.currentState='vgood'"/>
(I have tried with this , but its not working , the mx:property is not accepting the handler attribute ) )
seems Flex learning curve is so big .

Changing state of application from within a custom component

Hello, I have several custom components all of which are included in the parent application.
When I try to change state from a custom component, I get an error saying "undefined state: state name". How do I change the state of the application from within a custom component ? All the states are defined in the parent application.

@linrsvp,
If you are using Flex3 try Application.application.currentState = "somestate";
If you are using Flex4 try FlexGlobas.topLevelApplication.currentState = "somestate";
Don't forget to import the corresponding namespaces for the above.
Thanks,

Why we need State?

Hi, dear all, I am reading what's new in flex4 these days, and found the states has some big changes in flex4 rather then flex3, but I can not realize what is the benefits with use states? actually all state does is to add/remove some components, or make some changes on a compnent, but I can even do that with turn on/off the component's visible settings, or change some other properties, so why state? I know there must be the reason that flex provide the states, and make it more easy to use. can some body give me some prompt abouth this? Regards, Mike.

Thanks for your response EvyatarBH and Kumar Pratik.
I think in the case EvyatarBH said, yes, it was much easier to set propertie values on differents states.
If there are lot of state, and the controls always to be different size, then this may replace dozened of if...else..(s)
For the example Kumar gave out, actually I understood what was the point.
But I think that may only works when the "general" and "admin" page looks very similar.
Otherwise we may need to maintains a lot of controls and logics in one component, that will be much difficult I think.
Not sure if my understanding 100% correct, welcome for more replies.
Again, thanks for your answers, any better suggestions, please keep on.
Regards,
Mike

Complex View State handling

Hi,
I am trying to solve the following problem in Flex3:
I have layout with 4 quadrants ["Ch" for Child component
class]:
Ch1 Ch2
Ch3 Ch4
If I click a button in ch4 [i.e. state ch4a], it is supposed
to expand and cover Ch2, i.e.
Ch1
Ch4a
Ch3
Class Parent1 [inside Accordion]:
VBox
HBox1
<view:Ch1 width="60%" />
<view:Ch2 width="40%" />
/HBox1
HBox2
<view:Ch3 width="60%" />
<view:Ch4/>
/HBox2
/VBox
So in class Ch4 I created a view stateA which is based on
BaseState.
A) What makes more sense, fire event in class Ch4 on that
button click,
capture it in Parent1 and somehow [how?] change a layout so
that Ch2 is not there
but twice higher Ch4a is instead of it and no second part in
HBox2 ?
I would guess, ActionScript instead of MXML or is there a way
to express that in MXML?
Or how should that ActionScript look like ?
B) The other [easier] possibility is to get a handle to
Parent1 [parent container]
from the viewstateA of Ch4 and do something like:
<SetProperty target={this.parent} name="y" value="0">
Is it feasible? So far that didn't work for me. Any
suggestions?
Few other details:
1) it's all in Cairngorm AIR app;
2) that button in Ch4 is on one side a toggle button between
view states,
on the other side processing is completely different, but I
can handle that through calling
2 different private functions. I am saying only in one
state[BaseState] that event should be fired.
3) Background: Ch1 and Ch3 have lots of dropdowns, and what
user selected would be displayed
in Ch4A [that top portion], so user "Signs" that info, that's
a point of the whole screen.
Is there easy way to pass these selections to Ch4 ?
As of now, it's all buried deep inside some complex obscure
VOs .
Any help is very appreciated.
Thank you in advance,
Oleg.

The robot method is quite slow, and it can only capture images that are actually on the screen in the foreground. In any case, I stumbled on this article: [Performance Improvement Techniques for JavaFX Applications|http://javafx.com/docs/articles/performance/] that mentions the 'cache' member variable of a Node/Group can be used to tell the system to convert the Node to a bitmap (internally) for performance improvement. I haven't done any testing of my own, but it's an easy addition if you have a performance sensitive app.

And/or if statement in rtf templates.

Hi all,
I'm using XML Publisher 4.5.
I have created a word template file (rtf) for my reports. I need to be able to show some content in the template file by using and and/or if statement.
fx. <?if:doc_type='STANDARD'?> OR <?if:doc_type='DEFAULT'?>
How can I do this?
In advance thank you.
Best regards
Kenneth

Hi D,
Thank you for your answer.
I have seriously thought about that solution; but I don't think it's a smart way to do it.
If i do it like that, i need to copy the whole table and paste it inside the if statements.
I have two xml elements that I need to make the decisions on. POH_PO_TYPE & CP_RELEASE_NUM.
POH_PO_TYPE can be: STANDARD, RELEASE or BLANKET.
CP_RELEASE_NUM can be: '' or N
If POH_PO_TYPE is RELEASE AND CP_RELEASE_NUM is not ''
OR POH_PO_TYPE is STANDARD
OR POH_PO_TYPE is BLANKET AND CP_RELEASE_NUM is ''
THEN show table (which contains the whole PO).
It shall show the content of the PO in any of these cases.

Filename in import statement

Hi srinivas bobbala,
Thank you for your response.But I think my quesition was not clear.My ques... is for suppose there is one datafile for importing like.. "datafile_21" Here my intention is it takes file from datafile_21 only but it appears in import statement like datafile_21<<curmon>>.
import database sample.sample data from data_file "c:\\ABC\datafile_21_AUG.txt" using server rules_file datafile on error abort;
In this it takes datafile from datafile_21.But it appears like datafile_21_AUG in import statement.This AUG coming from batch file.
Essmsh c:\\ABC\loadmxl.mxl %curmon%

No it is not possible.
I assume the data file "datafile_21" is first renamed to datafile_21_${CurrMth} in the batchscript.
After that this data file *datafile_21_${CurrMth}* is pointed in the import statement.
In the logs you will see this file as datafile_21_Aug.

Help with if statement in cursor and for loop to get output

I have the following cursor and and want to use if else statement to get the output. The cursor is working fine. What i need help with is how to use and if else statement to only get the folderrsn that have not been updated in the last 30 days. If you look at the talbe below my select statement is showing folderrs 291631 was updated only 4 days ago and folderrsn 322160 was also updated 4 days ago.
I do not want these two to appear in my result set. So i need to use if else so that my result only shows all folderrsn that havenot been updated in the last 30 days.
Here is my cursor:
/*Cursor for Email procedure. It is working Shows userid and the string
You need to update these folders*/
DECLARE
a_user varchar2(200) := null;
v_assigneduser varchar2(20);
v_folderrsn varchar2(200);
v_emailaddress varchar2(60);
v_subject varchar2(200);
Cursor c IS
SELECT assigneduser, vu.emailaddress, f.folderrsn, trunc(f.indate) AS "IN DATE",
MAX (trunc(fpa.attemptdate)) AS "LAST UPDATE",
trunc(sysdate) - MAX (trunc(fpa.attemptdate)) AS "DAYS PAST"
--MAX (TRUNC (fpa.attemptdate)) - TRUNC (f.indate) AS "NUMBER OF DAYS"
FROM folder f, folderprocess fp, validuser vu, folderprocessattempt fpa
WHERE f.foldertype = 'HJ'
AND f.statuscode NOT IN (20, 40)
AND f.folderrsn = fp.folderrsn
AND fp.processrsn = fpa.processrsn
AND vu.userid = fp.assigneduser
AND vu.statuscode = 1
GROUP BY assigneduser, vu.emailaddress, f.folderrsn, f.indate
ORDER BY fp.assigneduser;
BEGIN
FOR c1 IN c LOOP
IF (c1.assigneduser = v_assigneduser) THEN
dbms_output.put_line(' ' || c1.folderrsn);
else
dbms_output.put(c1.assigneduser ||': ' || 'Overdue Folders:You need to update these folders: Folderrsn: '||c1.folderrsn);
END IF;
a_user := c1.assigneduser;
v_assigneduser := c1.assigneduser;
v_folderrsn := c1.folderrsn;
v_emailaddress := c1.emailaddress;
v_subject := 'Subject: Project for';
END LOOP;
END;
The reason I have included the folowing table is that I want you to see the output from the select statement. that way you can help me do the if statement in the above cursor so that the result will look like this:
emailaddress
Subject: 'Project for ' || V_email || 'not updated in the last 30 days'
v_folderrsn
v_folderrsn
etc

How do I incorporate a if else statement in the above cursor so the two days less than 30 days since last update are not returned. I do not want to send email if the project have been updated within the last 30 days.

When would I use an if, for or while statement in Small Basic and what is the difference between the three?

I have a Y9 Computer Science Exam next week and I know that this will probably be one of the questions on it so I need to know the answer. What is the difference?

An If statement executes once IF the statement is true:
If 1 = 2/2 Then
Textwindow.writeline("True")
EndIf
A While statement executes WHILE the statement is true:
While 4 = 2+2
'Will keep looping while it is true
EndWhile
A For statement loops a number in increment:
For i = 1 to 10
'Every time through, i gets bigger by one until it equals 10
EndFor
It is written: "'As surely as I live,' says the Lord, 'every knee will bow before me; every tongue will acknowledge God.'" Romans 14:11

If statement in sql

regarding the following sql:
SELECT a.lname, a.fname, a.user_id, c.address, c.city,
c.zip, c.addresstypeid, d.descriptor as state
FROM users a, address c, maintstatetype d
WHERE a.user_id = c.user_id(+)
AND c.statetypeid = d.statetypeid(+)
AND c.addresstypeid in (1,2,3,4)
I have a database of users and addresses. Each user can
have multiple addresses and the addresses are
designated by addresstypeid. In plain english, what I want
to pull is "If they have an addresstypeid of 1, pull that one
only, if not, check if they have a 2 and use that, if not, check
for a 3, etc..".
Any help with this?

What you want, then, is to pull the address with the minimum addresstypeid ..
SELECT a.lname, a.fname, a.user_id, c.address, c.city,
c.zip, c.addresstypeid, d.descriptor as state
FROM users a, address c, maintstatetype d
WHERE a.user_id = c.user_id(+)
AND c.statetypeid = d.statetypeid(+)
AND c.addresstypeid =
(select min(c2.addresstypeid)
from address c2
where c2.userid=a.userid
I'm not sure what this will do to your outerjoin, though. You might have to get funky with a union ...
SELECT a.lname, a.fname, a.user_id, c.address, c.city,
c.zip, c.addresstypeid, d.descriptor as state
FROM users a, address c, maintstatetype d
WHERE a.user_id = c.user_id
AND c.statetypeid = d.statetypeid
AND c.addresstypeid =
(select min(c2.addresstypeid)
from address c2
where c2.userid=a.userid
Union all
SELECT a.lname, a.fname, a.user_id, to_char(null), to_char(null),
to_char(null), to_char(null), to_char(null)
FROM users a
WHERE not exists
(select 1
from address c
where c.userid=a.userid
)

'IF' statement in a select statment?

I have the following cursor in a package specification;
cursor c_sales_code is
select sales_condition||' MC '||sales_option
from sales;This will return something like: 'T300 MC 9'
MC means 'multiple choice' for when there are multiple options. Although, sales_option is sometimes null and in this case I just want 'T300' to be returned, not 'T300 MC'.
How would I go about doing this?
Thanks,

Use
CASE and DECODE
to add the functoinality of Conditional Statements in Your SQL Statements..
These two CASE / DECODE will help you to get your desired output

IF Statement in Select

I need to choose between value1 and value2 within a select statement.
TableA
Flag (char)
Value1
Value2
ItemDesc
pseudo code
select ItemDesc, (if Flag = 'y' then Value1 else Value2) as Price from TableA;
How can this be done?

select   itemdesc,
         sum (case
                 when flag = 'y'
                    then (case
                             when value1 < 10
                                then value1 * 1.2
                             else value1
                          end)
                 else value2

If statement in select statement alias

I have the following select statement. It has the alias Survivors, Deaths and "All Cases". Is it posible to use :P_LANGUAGE variable to say that -- IF :P_LANGUAGE = FRENCH THEN alias are Survivants for survivors, Décès for Deaths, Tous_les_cas for All Cases. Please advise
SELECT ALL T_NTR_MULTIBAR.CAT, T_NTR_MULTIBAR.NUM_CASES_LEFTBAR AS Survivors,
T_NTR_MULTIBAR.NUM_CASES_MIDDLEBAR AS Deaths, T_NTR_MULTIBAR.NUM_CASES_RIGHTBAR AS "All Cases"
FROM T_NTR_MULTIBAR
WHERE INSTANCE_NUM = :P_INSTANCENUM
order by ORDERS

You may not be able to add this condition inside the SQL Statement. But you can add this condition outside the statement, if you're using PL/SQL...
IF :p_language = french THEN
SELECT ALL t_ntr_multibar.cat,
t_ntr_multibar.num_cases_leftbar AS survivors,
t_ntr_multibar.num_cases_middlebar AS deaths,
t_ntr_multibar.num_cases_rightbar AS "All Cases"
ELSE
END IF;

If Statement in PLD

I'm trying to set up a formula similiar to an If then statement with the PLD, and not having any luck. I need to create a formula on a sales order that says if there is no frieght on the order display "0.00".
Thanks.

Hi,
Create a field with empty value (Say field ID is 100).
Create a formula field which equals fields 100 and 186 (Say field ID is 101).
Create a formula field which has "not equals" as relation, within fields 100 and 186 (Say field ID is 102).
Create a field with the text 0. Link it with the field 101. Put it in the same place as the 186.
Link the 186 field with the 102.
Result: 0 will be shown when 186 is empty, value of 186 when is not empty.
Hope is clear,
Ibai Peñ

If statement in Custom Calculation Script

I have 16 fields and if even one of them ="1" I have to list it in another field. I do not want to count or sum. If one of those fields has a 1 in it I just want the other field to display Y and if none have a 1 I want that field to display N.
Please help.
Thank you in advance~mjc

You need to write a compound logical statement to evaluate all of the values and that statement needs to evaluate to true or false.
Do you know how to write JavaScript?
Do you know how to enter JavaScript calculations into a form field?
For custom calculation of the text field I could write something like:
// define an array of the field names to check
var aNames = new Array("Text1", "Text2", "Text3", "Text4",
