How do I display variables with # in them?

Hello Cf peeps.
I let users of my site create unique usernames and upload pictures. They are then able to search those items for the exact name they entered.
Today a user signed up with the name goboy#4.
How can I avoid getting a cf error when on his profile page I output <cfoutput>#username#</cfoutput> where username = goboy#4?
Thanks!

Yes, because - as Reid said - # is a meaningful character in the composition of URLs... it's the separator between the path to the document, and an anchor within the document, eg:
http://domain/path/to/doc.html#nameOfAnchor
So you need to escape the # in the filename. Fortunately CF caters for this, with the urlEncodedFormat() function.
You should also familiarise yourself with how URLs work:

How do I create variables and store them?

How do I create variables and store them?

As someone already said, we need to know a little more about what you want to do with these variables, but in general, APEX Items are probably what you want. You can create APEX Items at the Application or Page level. Once you set the value of an item, you can reference it anywhere else in the application. So, if you have an item on page 1 called P1_ENAME, you can reference it on page 32 using bind variable syntax :P1_ENAME. If you just want to store but not display some information, you can use either a hidden page item or an Application Level item. Take a look at the 2 Day Developers Guide for more info.

How do I display variables in a query in Bex Analyser 7.0?

Is this option gone in 7.0? I know I can insert navigation pane or filters, but how do I display what variables have been used to run a particular query?
I run a query and there is no way of telling HOW I ran it... I am surely missing something here, no?
Also, I know that SAPBExQueries sheet is gone in 7.0. I used it to override variables values and force query/workbook refresh with the new variables (as a way of automation of a report). How do I go about this in 7.0 if I don't even see the variables anywhere? What other way of forcing a workbook to refresh for, say, 10 different clients?
Thanks,
A.

Jacob,
Many thanks for your reply.
As for Bex, you said:
"So any query needs to start in a default workbook design where you got the filter and nav pane. Then you got a "Variables Screen" option."
Regardless of whether I run a stand alone query, or I insert analysis grid, nav pane and filters in the design mode, my variables are not dislayed anywhere. What do you mean by "then you got a variables screen option"? Where is it? I checked toolbars, menus, properties, I couldn't find anything. I can, of course, change variables, if that's what you mean, but I still can't display them on my worksheet. So if somebody's looking at my query they have no idea what variables I used.
As for broadcasting, sorry, it's not an option. By "say 10 clients" I meant "say 100 clients" times 20 different managers i.e. 200 different variants (seperate reports) Not possible to use a broadcaster, I am afraid, as the list of clients, managers and fiscal periods (and other variables) changes too often and we need to have the flexibility.
By looking at the new 7.0 I fear we will need to stick to the version 3.5 for that reason. Worrying...
Cheers,
A.

How to get/display time with minutes in a test item

Dear experts,
Forms [32 Bit] Version 10.1.2.0.2 (Production)
Oracle Database 10g Express Edition Release 10.2.0.1.0 - Production
Oracle Toolkit Version 10.1.2.0.2 (Production)
PL/SQL Version 10.1.0.4.2 (Production)I've the following requirements.
In my form, there are three text items and one save button.
Text items named as
No_of_days --> Number data type
(user will enter number of days)
hours_limit --> Char data type with format mask (HH:MI);
(user will enter hours with minutes)
Upto_date_time --> date data type;
this field calculated as (No_of_days+hours_limit+sysdate)
User will enter No_of_days or hours_limit:
Based on the values I've to calculate Upto_date_time
Here is the problem:
1) If user doesn't enter hours_limit I want to show default time as " 04:00 PM"
2) If user enter hours_limit field we should allow them to enter in the following format
"HH24:MI" format;
what whould be suitable data type for hours_limit field..
I tried with char and i've set the format mask as ,
set_item_property('BLOCK3.hours_limit',format_mask,'HH:MI');
But I'm geeting the error
"FRM-50027:Invalid format mask for given datatype"
Please help to solve this problem,
Regards,
Karthi

Hi vansul ,
set_item_property('BLOCK3.hours_limit',format_mask,'HH:MI');
Format mast is only allowed to date data type fields.If i set the hours_limit item's data type as date , I'm getting the error message "ORA-01843:Not a valid month"..
How could i make this field only getting or display time with minutes?

How to create date variable with interval in VC

Hi Everyone,
I have 2 questions:
<u>My scenario:</u>
I am using a BI 7.0 Query which is having some variables. I want the same variables to be displayed in the VC output.
<u>Question 1:</u>
I know that how to bring these variables in variable screen, but when we use these queries, dont the variables in the variable screen automatically ask for the input?
I tried it but it is not happening automatically.
There are 2 inputs for queries with variables, i tried using both, but it is not working properly. Can any one tell me is it possible.
<u>Question 2:</u>
In this variable screen, I have to select date with interval format. but i dont know how to use variable with interval. ( Date with interval format).
I hope some one might have come across the same scenario .. If so please share with the solution me ..
Regards,
Chan

Ok .. Let me be very clear .. I think I confused you.
As you mentioned I have done every thing in query level.
I have created a query with a variable which is an interval based variable(date).
When I execute the query it asks for the dates to display the inbetween data.
I gave the inputs and the data is displayed properly.( So far what I have mentioned is all in Query designer).
In VC, I have used this query and it is having two ports named INPUT and VARIABLE. I know that I need to give input in variables. I selected the calander month variable from the list to display. After this I deployed the model. In the output screen the table is displayed and 1 text box is also available for the date input. I know that here I have to give date with same format as in Query designer output. I tried so many ways to give input by even selecting some other options like date picker but it is giving the following error - <b>Variable expects interval values; enter an interval.</b>
The date format which I m using in Query is "MM.YYYY" and I m using the same format in VC too.
Now I hope that u can understand better.
I want to know is there any other way through which this can enter interval value or what mistake I m doing in the above explained scenario?
Regards,
Chan

How to replace one variable with another in large number of queries

Hello guys!
I have this situation: our company needs to use one variable instead of another for certain amount of queries.
Is there some way to automatically replace one variable with another for a certain characteristic in big number of queries ( like 150 - 200 ) ? Doing this manually would take lots of time)
Apreciate your help!

you could try (at your own risk) the following:
1. search the technical id (ELTUID) of your variable in table RSZELTDIR
2. see where this variable is used in table RSZELTXREF (by filling RSZELTDIR-ELTUIID in RSZELTXREF-TELTUID)
3. add similar entries for your new variable
4. delete the entries for the old variable (they're part of the key, so you can't simply "change" them)

How to convert the Variable with soap header to non soap variable.

I am working on a customized flow simialr to ProcessSalesorderFulfillmentJMSCOnsumer and Requestor ABCS. I dont have the PIP codes for the Requestor adn JMS Consumer. i built my own Requester ABCS and JMS Consumer. When i am trying to send message from JMS Consumer to Requestor ABCS in a variable with a SOAP:Env and SOAP:body inside.
Becoz of this i was not able to put a condition in my bpel flows. If i put a condtion on this variable like switch inputvariable:part:OrderType='NEW' and it was failing with selection failure. I tried copying the variable to a new variable and then to check the condition still it does not work for me. How do i convert the SOAP Message Variable to Non SOAP Message Variable.
Can i know the message put by SIebel in JMS Queue was it SOAP converted adn then how they are going to handle in Process Sales order Requestor ABCS.

HI,
In JMS Consumer of order to cash pip, Instead of using a schema reference they use a Envolpe.zxsd file which will take care of conversion adn then other artibutes are mapped in a transformation file.
Please take an export of jms consumer in jdeveloper and reverse engineer the code of JMS COnsumer Service.
Envelope_To_ListOfSWIOrderIO is the xsl whcih converts the message in AIA Queue to a message in a SOAP. Please look into the transformation.

How to use shared variables with native c programs

Hello
What is the way to use shared variables with native c programs?
I have a c/c++ program that uses the NIDAQmx C-API to perform measurements. Now I want to communicate to a LabVIEW program via shared variables.
Is there a C-API for shared variables as there is for the NIDAQmx functionality? Where can I find further documentation? The document "Using the LabVIEW Shared Variable" mentions that one "can read and write to shared variables in ANSI C", but there are no hints about how and where to look.
Thanks in Advance

Hi user42,
with CVI 8.0, you cannot create or configure shared variables. However, you can read or write to an already configured LabVIEW 8.x shared variable from CVI using the DataSocket API.
In order to do this you need to have and DataSocket 4.3 or higher installed.
Here's a forum post about using the DataSocket functions a LabVIEW Shared Variables:
http://forums.ni.com/ni/board/message?board.id=180&message.id=24569&requireLogin=False
With CVI 8.1 and Measurement Studio 8.1 it's possible to use Shared Variables via the Network Varaiable Library (check out the end of the "Network-Published Shared Variable" section within the "Using the LabVIEW Shared Variable" documentation and the following link).
Datasocket with LabWindows/CVI and LabVIEW Real-Time:

(Bash) How to set a variable with text from a file? [SOLVED]

I'm having a little problem.
I have textfile with a single line of text. What I want to do is set a variable with that line of text. How do I go about doing that?
A simple var="text" wont work in this case, since the text in the file changes with another script of mine.
Thanks in advance.

if you have a file with more than one line but you only want the first line you could use 'head'
VAR=`head -n 1 file`

Why are you using dynamic SQL statements? Why not just use something like this instead in your PL/SQL. I also replaced the leading // in your Xpath with just / since you start from the root node.
select *
INTO l_dummy
from xmltable(XMLNAMESPACES('http://www.w3.org/2001/XMLSchema' AS "XSD", default 'http://schemas.xmlsoap.org/wsdl/'),
                '/definitions/types/XSD:schema/XSD:element'

                columns
                ab xmltype path '.' ) t;Also, the above returns two rows, which I suspect is not what you want. Here is the pure SQL version for you to debug.

How to Set a Variable with data from Srouce Data Store

Hello ODI Experts,
I have created a Physical & Logical Schema and a Source Data store to pickup data from a database table.
On the other hand, I have a few variable that I will pass in a web service call (ODIInvokeWebService tool).
Would yo please guide how I can set variables from my source data store.
Thanks & Regards,
Ahsan

Hello Bos/Damodhar/ODI Experts,
Doesn't it gives me a less optimized approach picking one column per query (per variable)?
Lets say, I have to pick 35 columns from a table and put those in 35 variables...It would mean running 35 queries for fetching one record from the database table.
Doesn't it seem less performance effective (less optimized)..a little scary..any thing better that I can do to make it more optimized?
Another question, what if multiple new values have come in the DB table, since I am using Refresh Variable, would this variable have multiple values in it?
Thanks for all your help,
Ahsan

How display variables with a button in a panel in java ?

I create an applet with three panels. The 1st panel contains a button which must post one panneau of panel type in the 2nd panel But this action does not work!!
the 2nd panel is initialized like this :
Panel panel2 = new Panel;
panel2.setBackground(new Color(0, 255, 0));
panel2.setLayout(borderLayout2);
this.add(panel2, BorderLayout.CENTER); the code of my button is:
public void actionPerformed(ActionEvent E) {
truc.truc();// method which creates panel
panel2.setBackground(new Color(255, 255, 180));
panel2.add(panneau, BorderLayout.CENTER); }the button is enable (because change of color is done)and if I post panel without using the button, it works.
thank you :)

Try panel2.validate()
It sounds like your panel isn't being laid out.

How to declare class variable with generic parameters?

I've got a class that declares a type parameter T. I know how to declare a static method, but this doesn't work for a static variable:
public class Test< T >
    * Map of String to instances of T.
    * error: '(' expected (pointing to =)
    * <identifier> expected (pointing to () )
   private final static < T > Map< String, T > MAP = new HashMap< String, T >();
    * Get instance of type T associated with the given key.
   public final static < T > T getType( String key )
      return MAP.get( key );

I'm trying to create a generic polymorphic Factory class that contains boilerplate code.
I don't want to have to rewrite the registration code every time I have a different return type and parameter.I haven't seen a case yet where that is reasonable.
If you have hundreds of factories then something is wrong with your code, design and architecture.
If you have a factory which requires large number of a varying input types (producing different types) then something is probably wrong with your code and design.
A reasonable factory usage is one where you have say 20 classes to be created and you need to add a new class every 3 months. Along with additional functionality represented by the class itself and perhaps variances in usage. Thus adding about 3 lines of code to one class is trivial. Conversely if you have hundreds of classes to be created by the factory and you are adding them daily then it is likely that
1. Something is wrong with the architecture which requires a new class every day.
2. You should be using a dynamic mechanism for creation rather than static because you can't roll out a static update that often.
More than that the idiom that leads to factory creation is different for each factory. A factory that creates a database connection is substantially different than the one used in dynamic rules logic processing. A generic version will not be suitable for both.
Actualy the only case I know of where such a factory might be seem to be a 'good' idea is where someone has gotten it into their head that every class should be represented by an interface and every class created by a factory (its own factory.) And of course that is flawed.

How to call a variable with a loop count in it

First - I have a variable called "stages" this is a number
that can vary. Because it can vary I want to run things in a loop
based on the number that comes up as the stages variable amount.
Second is a loop
<cfloop index="riderCount" from="1" to "9">
Next, I have a query
<cfquery name="getPts" datasource="#application.dsn#">
SELECT *
FROM fantasy_racers
WHERE proName='#pro#''
</cfquery)
** Note: variable pro is set before the query **
I have colums in my table: pts1, pt2, pts3, etc. all the way
to pts25 for each pro in the table.
Now to the heart of the matter
I want to get the amount in each column. EX.: #getPts.pts1#
but since the number of stages can vary I don't want to hard
code for 25 outputs when there may only be 7
so how can I call the column amount but utilize a ridercount
in place of the number
#getPts.pts
ridercount#

You can reference query variables in an array-of-structures
notation:
myQuery["MyColumn"][row]
so you could do something like this:
#getPts["pts" & riderCount][1]#
Combine that syntax with Query.CurrentRow and
Query.recordCount and you should be able to put a loop together
that solves your problem.

How do I display variables with # in them?
