How to retrieve a string value from a PHP function call

Should this string be the return value of the PHP function?
Or should it be embedded in the response HTML? Any examples?

This is what I got so far:
footer.mxml in Flex Builder 3:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute" creationComplete="ts_request()">
<mx:Script>
<![CDATA[
public function ts_request():void {
timestampRequest.send();
]]>
</mx:Script>
<mx:Canvas width="836" height="36"
backgroundColor="#05075C">
<mx:Label id="timestamp"
text="{timestampRequest.lastResult.timestamp}" color="#FEFEFE"
height="20" y="10" textAlign="left" width="221" x="10"/>
</mx:Canvas>
<mx:HTTPService id="timestampRequest" url="
http://www.ABC.com/timestamp.php"
useProxy="false" method="POST" />
</mx:Application>
Here is the timestamp.php on the www.ABC.com web server. I
have tested the php by directly access it with
"www.ABC.com/timestamp.php" and it shows the timestamp correctly:
<?php
putenv($timezone);
$Return = "<timestamp>".date("m/d/Y H:i:s", time())."
CST"."</timestamp>";
print($Return);
?>
When I run footer.mxml in Flex 3 Builder, I got an error:
This file cannot be launched.
Where did I do wrong?

How to pass multiple query string values using the same parameter in Query String (URL) Filter Web Part

Hi,
I want to pass multiple query string values using the same parameter in Query String (URL) Filter Web Part like mentioned below:
http://server/pages/Default.aspx?Title=Arup&Title=Ratan
But it always return those items whose "Title" value is "Arup". It is not returned any items whose "Title" is "Ratan".
I have followed the
http://office.microsoft.com/en-us/sharepointserver/HA102509991033.aspx#1
Please suggest me.
Thanks | Arup
THanks! Arup R(MCTS)
SucCeSS DoEs NOT MatTer.

Hi DH, sorry for not being clear.
It works when I create the connection from that web part that you want to be connected with the Query String Filter Web part. So let's say you created a web part page. Then you could connect a parameterized Excel Workbook to an Excel Web Access Web Part
(or a Performance Point Dashboard etc.) and you insert it into your page and add
a Query String Filter Web Part . Then you can connect them by editing the Query String Filter Web Part but also by editing the Excel Web Access Web Part. And only when I created from the latter it worked
with multiple values for one parameter. If you have any more questions let me know. See you, Ingo

Urgent: How to exclude a particular value from the selection in the infopac

How to exclude a particular value from the selection in the infopackage.

Thank you,

Hi Sam,
You cannot do this directly as exclusion, but you can include all other values, even as ranges and thus exclude the particular value, else you can also try to do this by writing a routine.
Hope this helps...

How to get the string value from the RichSelectBooleanCheckBox component?

I added a validator to a RichSelectBooleanCheckBox component which is binded to a String attribute of a View Object.
I defined the mapping of boolean value to corresponding String value in the corresponding attribute binding in the page definition.
When the validate() method of my validator was invoked, the new value passed to the validate method() was a Boolean value instead of the converted String value.
I need to write validate() method generically so that it can handle more than one way of mapping boolean values to String values.
How can I get the converted String value in my validator method() from the RichBooleanCheckBox component that was also passed to the validate() method as a parameter?

use:
int num = Integer.parseInt(s);

How to get the query values from the url in a servlet and pass them to jsp

ok..this is the situation...
all applications are routed through a login page...
so if we have a url like www.abc.com/appA/login?param1=A&param2=B , the query string must be passed onto a servlet(which is invoked before the login page is displayed)..the servlet must process the query string and then should pass all those values(as hidden values) to the login jsp..then user enters username and pswd, then there should be another servlet which takes all the hidden values of jsp and also username and pswd, authenticates the user and sends the control back to that particular application along with the hidden values...
so i need help on how to parse the query string from the original url in the servlet, pass it out to jsp, and then pass it back to the servlet and back to the original application...damnn...any help would be greatly appreciated...thanks

ok..this is the situation...Sounds like you have a bad design on your hands.

How to pass a string value from XL sheet cell to SQL query.

Below is My code:

Thanks,
Priya

What does "XL" (whatever that is) have to do with Crystal Reports which is what you are obviously working with have to do with the Oracle database?
The rules for using Crystal with Oracle are quite clearly described in all the Crystal Reports docs ... you MUST use IN OUT ref cursors unless you are doing direct table or view access.

Copying string value from the main file to a thread!

i.e. I have a string like this in the main file:
private static String a = new String("1");
and the value from "a" shuld be copied so that a variable "a" in thread.java gets the same value!
how to do this?
thanks
.leonard

1) If main has access to a in thread, have main copy it over.
2) Add a getA() function to main and have thread use that.
3) Design the program better from the ground up.

F4IF_INT_TABLE_VALUE_REQUEST - how can I return all values from the line?

Hi,
I'm using FM F4IF_INT_TABLE_VALUE_REQUEST to show a pop-up with my internal table values. The internal table has 3 fields, ATINN, ATZHL and a description field ATWTB. ATINN and ATZHL are needed to complete the unique table key, however this FM will only return the value of one field in any line I select.
How can I see all the values in the line I select in the return table?
My code is as follows:

          wa_cawnt-atzhl TO wa_list-atzhl.
    APPEND wa_list TO tbl_list.
ENDLOOP.

Hi,
Use the structure DYNPFLD_MAPPING
With this internal table you can easily define that you want to return
other columns of the hit list in addition to field RETFIELD to the
screen.
In this IT you can MAP the screen fields to the serch help screen fields this has three fields
FLDNAME this is the field anme from the search help
FLDINH This has to be blank which would be field with the field value that you want to map
DYFLDNAME THis is the screen field name.
So here you can get the values for the other fields that you want which are on the search help just populate the name of the fields in FLDNAME.

How to align a String value to the right side inside a table column?

Hi,
I have a text view inside a table column which is mapped to a string attribute. I need to align the text in the text view to the right hand inside the table column. But its always getting aligned towards the left side. I have tried by setting the <b>hAlign</b> property of Element properties of Text View to <b>right / forced right</b> but still the text is getting aligned to the left side.
How do I align the String values in Text View towards the right hand side inside a Table Column?
Thanks and Regards,
Sayan Ghosh

Hello Sayan,
if i do get it right, you are adding an TextView element to a Table Cell. Then you should consider setting aligment within the particular cell. By calling:
YourCell.setHorizontalAlignment(CellHAlign.RIGHT)

I am wanting to exactly match two ID numbers from two differing worksheets within one work book. Once matched I am wanting to retrieve a row value from the second worksheet into the first. Any help much appreciated.

I am wanting to exactly match two ID numbers from two worksheets within the one work book. ID numbers are non linear. Once exactly matched I wish to retrieve a corresponding row value from worksheet two and have it appear in worksheet one against the correct ID number. I have been looking at IF, VLOOKUP, and MATCH functions and suspect that what I want to do requires a combination of two or more. Any help will be greatly appreciated.
regards Vaughanh

Vaughan,
Data A:D is all cells start at column A thru column D.
There is built-in help using the menu item "View > Show Function Browser" in the search field (top right) you can enter vlookup and you will see the detailed description.
From this we see:
VLOOKUP
(search-for, columns-range, return-column, close-match)
search-for: The value to find. search-value can contain any value type.
columns-range: A range of cells. range is a reference to a single range of cells, which may contain values of any type.
return-column: A number that specifies the relative column number of the cell from which to return the value. return-column is a number value. The leftmost column in the range is column 1.
close-match: An optional value that determines whether an exact match is required.
close match (TRUE, 1, or omitted): If there’s no exact match, select the column with the largest top-row value that is less than the search value. Wildcards can’t be used in search-for.
exact match (FALSE or 0): If there’s no exact match, return an error. Wildcards can be used in search-for.
So... the 2,0 means return the value form the same row as the lookup value but from the 2nd column of the range. 3, 0 means from the 3rd column. the ", 0" means exact match

How can I pass a value from the datagrid to my textinput

Hi i am new in adobe flex!
I have only one row in my datagrid and it has 5 dataField. Those dataFields are id, ln, fn, kurs, yr. I want to pass those value into a textinput respectively.
Heres my code:
<mx:DataGrid x="396" y="10" width="110" height="124" id="dginfo" enabled="true" dataProvider="{studinfo.lastResult.datas.data}" creationComplete="studinfo.send()" editable="false" visible="true">
                        <mx:columns>
                            <mx:DataGridColumn headerText="C0" dataField="username" visible="false"/>
                            <mx:DataGridColumn headerText="C1" dataField="id"/>
                            <mx:DataGridColumn headerText="C2" dataField="ln"/>
                            <mx:DataGridColumn headerText="C3" dataField="fn"/>
                            <mx:DataGridColumn headerText="C4" dataField="kurs"/>
                            <mx:DataGridColumn headerText="C5" dataField="yr"/>
                        </mx:columns>
                    </mx:DataGrid>
I want to pass it here (code)
<mx:TextInput backgroundColor="#ABA5A5" editable="false" enabled="true" color="#000000" horizontalCenter="-50" verticalCenter="-71" id="idview" text="{data.id}"/>
                    <mx:TextInput id = "idview" editable="false" enabled="true" text="{data.ln}"/>
                    <mx:TextInput id="lnview"editable="false" enabled="true"text="{data.fn}"/>
                    <mx:TextInput id="fnview" editable="false" enabled="true" text="{data.kurs}"/>
                    <mx:TextInput backgroundColor="#ABA5A5" editable="false" enabled="true" id="yrview" text="{data.yr}"/>
My problem is that this code won't work, it won't diplay anything...:D

it must not display anything as data.ln doesnot have any value. in your code, in the text property of textfield, data is considered as a property of your application, a dynamic object; so even it doesnot have ln property, it is not showing error, neither displaying anything.
do you mean to populate your textfields if the datagrid row is selected? if so:
<mx:TextInput id = "idview" editable="false" enabled="true" text="{dginfo.selectedItem.ln}"/>
if you want to populate the same data without caring if it is selected in datagrid, you should not think like you are getting data from datagrid, instead, you are getting your values directly from the studinfo.lastResult
in such:
<mx:TextInput id = "idview" editable="false" enabled="true" text="{studinfo.lastResult.datas.data.ln}"/>
note: if your result contains more than one data, you should treat it as array:
studinfo.lastResult.datas.data[0].ln
