Use button to set a variable

hi, can someone help me.
I would like to use a couple of buttons that I made to set a variable. I'd like to use the instance name of the button(s) as the value stored as the variable. how can i code this?
thanks.

You can use the currentTarget of the event to target the button and acquire its name...
var btnName:String;
btn.addEventListener(MouseEvent.CLICK, storeName);
function storeName(evt:MouseEvent):void {
     btnName = evt.currentTarget.name;
     trace(btnName); // will trace "btn"

  • Application.cfm - Should I use queries or set session variables?

    Hi,
    I have an application that has many users for many different
    companies logged in at the same time using the system. I use the
    application.cfm to call and set a bunch of variables that make the
    system work, such as preferences and things. Would it be better to
    use 5 or 6 queries all pulling one record, or call the queries only
    once at the start of the session and set 30 to 50 session variables
    based on the query results? Which method would bog the system down
    less? It seems that session variables use quite a bit of memory.
    I'm just trying to get the "simple answer" for this, if that's even
    possible.
    Please let me know your thoughts and experience on this.
    Thanks much,
    Jeff W!

    In order to give you a simple "do it this way" answer, more
    information is needed.
    How long does it take to run those 5-6 queries on each
    request? How many users are logged in at peak times? How much data
    would you be storing in the session for each user? How much RAM do
    you have on your server?
    On one application, we've decided to go the session variable
    route. The size for each users' session maxes out at 2.5 KB. We
    have 512 MB dedicated to CF, but can easily scale up on the
    hardware we have to 1.5 GB or more. At 512 MB, 2.5 KB per user
    session, we can handle a little over 200,000 concurrent users
    (assuming all CF memory could be utilized for session variables,
    which isn't true). There are only 6,000 users total in our system,
    so we have quite a bit of headroom.
    Are you on CF8? If so, open up the server monitor, start
    monitoring, profiling, and memory tracking, and log in with a
    couple users (with your code setup to store all that info in the
    session). See how much storage each session takes. Then look at
    your server. How much RAM do you have? what do you currently have
    allocated to ColdFusion? What's your peak concurrent user level? Do
    you have headroom? Also, see if the benefits of storing it in the
    session are even worth it (how long do those 5-6 queries add to
    each requst?)

  • How to avoid escaped XML in "Set Workflow Variable" | "By Composing"

    Hi, I have a proplem building an XML document using the action : "Set
    Workflow Variable" | "By Composing" dialog.
    The value of an element on the left pane is a variable in the right pane.
    This variable contains a snippet of XML.
    The problem is that when I print out the newly created document the XML I
    added to it from the variable has been escaped :
    In the example below I created a new xml document called new XML in its
    child_2 element I set its value to the XML String "xml".
    As you can see, the value of child 2 has been escaped. Is there a way to
    turn this feature off ??

    Hi,
    I also have this problem. It seems that a crude way around it, is to use a quick
    fix via calling a business operation that performs string substitution to replace
    the escaped entity references (<) and (>) with "<" ">". I have done this
    and the approach works for me. Just be careful and make sure that the xml string
    your are cleaning up doesn't contain any of these entity reference that you would
    like to keep. Otherwise it will definitily break your xml. I hope you have that
    luxury.
    The easiest way to do is is to write a StringUtil class with a static replace
    function, replace(source, old, new), expose this method as a business operation,
    then call twice to convert your xml string.
    I know this is pretty pathetic, but might help in the meanwhile until BEA provides
    this functionality.

    In Windows 9x you would set it up in the autoexec.bat file
    ie.
    SET PATH=%PATH%;c:\jdk1.4.2\bin\;
    where c:\jdk1.4.2\ is the path where you installed Java.
    In Windows 2000 and XP
    Right click on My Computer->Properties->Advanced Tab->Environment Variables... Button.
    If you see a PATH in System Variables, click that and edit it. If you don't, you will need to create a new System variable.

  • How to set a variable in portal session using web dynpro java.

    Hi,
    I have created a web dynpro application, which is running inside portal. I have created a role called "R1". Inside role R1, i have created 3 workset W1, W2 and W3. and inside each workset i have some pages and iviews.
    My requirement is when user logins to the portal , and when he clicks on role R1 for the first time, a login page should come (so that we can do revalidation), and when he enters his password again in that login page , then only workset W1, W2 and W3 should be visible/accessible to him and after successful revalidation, if he clicks again on role R1, in that particular portal session, than that login page should not come.
    for this, i thought i will set a variable in portal session, whenever user successfully revalidated himself, and if after successful revalidation he clicks again on role R1, i will check in doinit method of webdynpro whether variable is set or not (which i already set on successful revalidation), and if it is set then i will do Donavigation else i will present login page to the user.
    Can anyone tells me how to set a variable in portal session using web dynpro java.
    thanks

  • How to set #HOST# variable used in Chart template using Multiple Domains?

    I have a extended question to How can I set #HOST# variable referenced in the Chart template?
    In addition to the Proxy layer, we are looking to use multiple sub-domain names into the same Oracle APEX instance (through the one DAD) each mapped to a different application id. Therefore I don't think the solution in the link will work for me - as this embeds a single domain name in the DADS.CONF.
    Two questions:
    - Is it possible to set the "HTTP_HOST" in "dads.conf" using an existing HTTP Header value? - my proxy can pass on the original domain as "HTTP_X_FORWARDED_HOST". So if it was possible to use (say: using whatever form/syntax of parameterisation is available) ?
    >
    PlsqlCGIEnvironmentList HTTP_HOST=%{HTTP_X_FORWARDED_HOST}
    >
    If it can then that would work for me. It would be great if modl_plsql handled this out of the box as I understand the "X-FORWARDED" approach is pretty standard in the proxy world including passing on original IP addresses. Hitting an phpinfo() site shows headers
    >
    HTTP_X_FORWARDED_FOR     192.168.2.100
    HTTP_X_FORWARDED_HOST     dev.mycompany.com:443
    HTTP_X_FORWARDED_SERVER     mycompany.com
    >
    - Alternatively is it possible in APEX environment to set the #HOST# from the HTTP Header "HTTP_X_FORWARDED_HOST" if it exists for all requests?
    Thanks

    Hi Donna,
    changing the CGI environment variables HTTP_HOST, REQUEST_PROTOCOL and SERVER_PORT is the correct way how to resolve this, because it appears that your hiding the web server where you have installed mod_plsql or EPG by a different outside facing web server (also called reverse proxy). That's why APEX gets the host name, protocol and port of the internal web server, but should actually get the values of your reverse proxy web server. Can can fix that by changing the following CGI environment variables.
    HTTP_HOST should just contain the domain name (no protocol or port). For example: www.oracle.com
    REQUEST_PROTOCOL should contain http or https
    SERVER_PORT should be the port for https
    I don't want to add a new cgi variable called HOST because HOST sounds so generic and it might interfere with something else running in our environment. Or, I don't want to change the plsql cgi environment variable (such as HTTP_HOST) because many developers may use owa_util.get_cgi_env('HTTP_HOST') to get the current server. If the SERVER_PORT is part of the #HOST# then what could I change it to if it needs to be null. If you leave it blank, then the default SERVER_PORT comes from the CGI variables.The value of HTTP_HOST is wrong anyway and points to your internal web server, but I assume your developers actually want to get the host name of your external web server if they use it to generate absolute URLs. That's why I wouldn't bother and set it to the correct host name.

  • How to set ENV variable using user profile in solaris 10 while using ssh

    Hi,
    Please help me in setting the environment variable using user profile file while using ssh method of connection (Can I use the same ~/.profile file?)
    when i am logging in using the telnet, the environment variable is automattically set, but not when I am using SSH.
    Thanks in advance
    ushas symon

    Please list your .profile and a ls -la of your home directory.
    also list the result of env after your logged through telnet and ssh.
    There should be no difference - it depends mostly on your login shell which startup script it executes. ksh uses .profile, bash: bash_profile then .profile.

  • Using Powershell to set Multiple timed.servers with variables

    Having an issue using PowerShell to set 3 timed.servers which are defined in a variable. Running the commands: $TimeServers = "IPaddress1,IPaddress2,IPaddress3"Set-NaOption -OptionName timed.servers -OptionValue $TimeServers Thanks in advance!

    Hi, The Set-NaOption CmdLet -optionvalue parameter expects a string and it shouldn't matter if that's a comma delimited string containing multiple IP Addresses. I noticed that whilst the cmdlet thows an error it does actually set the option value for all servers so this seems like it could be a bug (IMO). It might be possible to invoke the API using "Invoke-NaSystemApi" but I checked the ZAPI and noticed this also fails using ZExplore from the SDK: ZAPI Request: <?xml version="1.0" encoding="UTF-8"?>
    <netapp  xmlns="http://www.netapp.com/filer/admin" version="1.21">
      <options-set>
        <name>timed.servers</name>
        <value>192.168.100.10,192.168.100.11,192.168.100.12</value>
      </options-set>
    </netapp> ZAPI Results: <?xml version='1.0' encoding='UTF-8' ?>
    <netapp version='1.1' xmlns='http://www.netapp.com/filer/admin'>
        <!-- Output of options-set [Execution Time: 8610 ms] -->
        <results reason='Unable to set option: timed.servers' errno='13001' status='failed'>

            <cluster_constraint>same_preferred</cluster_constraint>
            <message>1 entry was deleted.
    </message>
        </results>
    </netapp> So i think the options are either using the "Set-NaOption" cmdlet with the -SilentlyContinue parameter or the "Invoke-NaSsh" cmdlet with -ErrorAction stop.As a work around i'd recommend something like: [String]$servers = "192.168.100.10,192.168.100.11,192.168.100.12"
    [String]$command = "options timed.servers $servers"
    Try{
       Invoke-NaSsh -Command $command -ErrorAction Stop
       Write-Host "Executed Command: $command"   
    }Catch{
       Write-Warning -Message $("Failed Executing Command: $command. Error " + $_.Exception.Message)

  • Setting bpel variable using external java code

    Hi all
    I would like to ask if there is a way to set bpel process variable during process execution from external java code using java api without using java embedding code?!!
    Thnx in advance

    Hi, I wanna to know if it is possible at all to edit/update value of variables in a process instance via external java code?
    In fact I don't believe that we can set a variable remotely using java APIs.Am I right?
    For example,is it possible to change the value of a field in the user task form(that is sent to a user to fill and complete the task)?

  • Can we set a variable used inside the template from the java code.

    Hi everybody,
    I am uploading template,sub template and data xml fle to generate the preview using XDO API's. My main template is calling a sub template so it needs to import the sub template in the main template.since i am uploading my files on a particular server,my subtemplates has been put on different path as specified in the main template.
    so i need to change the subtemplate path dynamically at run time.
    is there any way i can pass this information to my main template at run time.
    one solution could be,my rtf template has a variable 'i' inside it,which is setting the file path to include my subtemplate like this :
    <?xdoxslt:set_variable($_XDOCTX, i ,"import:file:///c:/Temp/htmlmarkup.xsl")?>
    <?xdoxslt:get_variable($_XDOCTX, i )?>
    now is there any way i can set this variable at run time from my external java code.?
    Thanks,
    Anuradha

    Thanks for the response.
    but i still am looking for the solution.
    if both my template and subtemplate are in the same directory then atleast
    <?import:file:../htmlmarkup.xsl?> should work.
    but its not working...i m getting following error:
