  • Attaching a List of Value [LOV] to an existing page item in APEX

    - by Sathya
    I'm pretty new to APEX ( well, just started using it ~an hour ago), and I'm stuck at a pretty basic level. I've created a simple form with all the required fields. I've created a simple LOV. I can't seem to figure out how to Attach the LOV to the existing item. I tried to attach the LOV by heading over to the item's property and selecting the LOV I created, but it just doesn't seem to attach. Is this a bug with APEX or am I doing something wrong ? I'm using APEX 4.0 EA 2 [ http://tryapexnow.com ]

  • Get "term is undefined” error when trying to assign arrayList to List component dataSource

    - by user1814467
    I'm creating an online game where people log in and then have the list of current players displayed. When the user enters a "room" it dispatches an SFSEvent which includes a Room object with the list of users as User objects in that room. As that event's callback function, I get the list of current users which is an Array, switch the View Stack child index, and then I wrap the user list array in an ArrayList before I assign it to the MXML Spark List component's dataSource. Here's my code: My Actionscript Code Section (PreGame.as): private function onRoomJoin(event:SFSEvent):void { const room:Room = this._sfs.getRoomByName(PREGAME_ROOM); this.selectedChild = waitingRoom; /** I know I should be using event listeners * but this is a temporary fix, otherwise * I keep getting null object errors * do to the li_users list not being * created in time for the dataProvider assignment **/ setTimeout(function ():void { const userList:ArrayList = new ArrayList(room.userList); this.li_users.dataProvider = userList; // This is where the error gets thrown },1000); } My MXML Code: <?xml version="1.0" encoding="utf-8"?> <mx:ViewStack xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" initialize="preGame_initializeHandler(event)" > <fx:Script source="PreGame.as"/> <s:NavigatorContent id="nc_loginScreen"> /** Login Screen Code **/ </s:NavigatorContent> /** Start of Waiting Room code **/ <s:NavigatorContent id="waitingRoom"> <s:Panel id="pn_users" width="400" height="400" title="Users"> /** This is the List in question **/ <s:List id="li_users" width="100%" height="100%"/> </s:Panel> </s:NavigatorContent> </mx:ViewStack> However, I keep getting this error: TypeError: Error #1010: A term is undefined and has no properties Any ideas what I'm doing wrong? The arrayList has data, so I know it's not empty/null.

  • Python/Django: Which authorize.net library should I use?

    - by Parand
    I need authorize.net integration for subscription payments, likely using CIM. The requirements are simple - recurring monthly payments, with a few different price points. Customer credit card info will be stored a authorize.net . There are quite a few libraries and code snippets around, I'm looking for recommendations as to which work best. Satchmo seems more than I need, and it looks like it's complex. Django-Bursar seems like what I need, but it's listed as alpha. The adroll/authorize library also looks pretty good. The CIM XML APIs don't look too bad, I could connect directly with them. And there are quite a few other code snippets. What's the best choice right now, given my fairly simple requirements?

  • Zend php memory memory_limit

    - by RepDetec
    All, I am working on a Zend Framework based web application. We keep encountering out of memory errors on our dev server: Allowed memory size of XXXX bytes exhausted (tried YYYY... We keep increasing memory_limit in php.ini, but it is now up over 1000 megs. What is a normal memory_limit value? What are the usual suspects in php/Zend for running out of memory? We are using the Propel ORM. Thanks for all of the help! Update I cannot reproduce this error in my windows environment. If I set memory_limit low (say 16M), I get the same error, but the "tried to allocate" amount is always something reasonable. For example: (tried to allocate 13344 bytes) If I set the memory very low on the (Fedora 9) server (such as 16M), I get the same thing. consistent, reasonable out of memory errors. However, even when the memory limit is set very high on our server (128M, for example), maybe once a week, I will get an crazy huge memory error: (tried to allocate 1846026201 bytes). I don't know if that might shed any more light onto what is going on. We are using propel 1.5. It sounds like the actual release is going to come out later this month, but it doesn't look like anyone else is having this problem with it anyway. I don't know that Propel is the problem. We are using Zend Server with php 5.2 on the Linux box, and 5.3 locally. Any more ideas? I have a ticket out to get Xdebug installed on the Linux box. Thanks, -rep

  • LISP: Keyword parameters, supplied-p

    - by echox
    At the moment I'm working through "Practical Common Lisp" from Peter Seibel. In the chapter "Practical: A Simple Database" (http://www.gigamonkeys.com/book/practical-a-simple-database.html) Seibel explains keyword parameters and the usage of a supplied-parameter with the following example: (defun foo (&key a (b 20) (c 30 c-p)) (list a b c c-p)) Results: (foo :a 1 :b 2 :c 3) ==> (1 2 3 T) (foo :c 3 :b 2 :a 1) ==> (1 2 3 T) (foo :a 1 :c 3) ==> (1 20 3 T) (foo) ==> (NIL 20 30 NIL) So if I use &key at the beginning of my parameter list, I have the possibility to use a list of 3 parameters name, default value and the third if the parameter as been supplied or not. Ok. But looking at the code in the above example: (list a b c c-p) How does the lisp interpreter know that c-p is my "supplied parameter"?

  • Domain Keys, DKIM and Sendmail

    - by Daniel
    When I am using DomainKeys and DKIM together on a linux system, do I run both of them on the same port? DomainKeys: /usr/bin/dk-filter -l -p inet:8891@localhost -d example.com -s /var/db/ domainkeys/default.key.pem -S default DKIM: /usr/bin/dkim-filter -l -p inet:8891@localhost -c simple -d example.com -k /var/db/dkim/mail.key.pem -s mail -S rsa-sha256 -u dkim -m MSA Or do I do something like this: DomainKeys: /usr/bin/dk-filter -l -p inet:8892@localhost -d example.com -s /var/db/ domainkeys/mail1.key.pem -S default DKIM: /usr/bin/dkim-filter -l -p inet:8891@localhost -c simple -d example.com -k /var/db/dkim/mail2.key.pem -s mail -S rsa-sha256 -u dkim -m MSA Just wondering since information about DomainKeys and DKIM tell you to run them on the same port: http://www.elandsys.com/resources/sendmail/domainkeys.html http://www.elandsys.com/resources/sendmail/dkim.html I want to run both of them together, is this a bad idea?

  • Tips for transitioning from Visual Basic to Xcode

    - by Cyclone
    I've been programming in VB.net for a while now, and I finally got access to a mac to make ipod apps. What are some useful sites, videos, etc. that could help me get used to Objective C and the Xcode IDE? I've stumbled upon the samples on the apple dev site, but none of them really give good examples which I could learn the syntax of the language from. Thanks for the help, Objective C is really a big change from VB.net!

  • Webrick transparent proxy

  • Stream a continously growing file over tcp/ip

    - by Grinner
    Hello, I have a project I'm working on, where a piece of Hardware is producing output that is continuously being written into a textfile. What I need to do is to stream that file as it's being written over a simple tcp/ip connection. I'm currently trying to that through simple netcat, but netcat only sends the part of the file that is written at the time of execution. It doesn't continue to send the rest. Right now I have a server listening to netcat on port 9000 (simply for test-purposes): netcat -l 9000 And the send command is: netcat localhost 9000 < c:\OUTPUTFILE So in my understanding netcat should actually be streaming the file, but it simply stops once everything that existed at the beginning of the execution has been sent. It doesn't kill the connection, but simply stops sending new data. How do I get it to stream the data continuously? Thanks for any help!

  • Linq : problem with primary key

    - by Nickson
    I get the following error message The table/view 'TABLE1' does not have a primary key defined and no valid primary key could be inferred. This table/view has been excluded. To use the entity you will need to review your schema, add the correct keys and uncomment it when I try to add a view to an Entity Data Model. For testing, I have created a very simple view and I still get the error. below is the view definition SELECT DISTINCT TOP (100) PERCENT MIN(id) AS Expr4, MIN(EmpNo) AS Expr1, MIN(Name) AS Expr2, MIN(Category) AS Expr3 FROM dbo.MYView1 GROUP BY id does any one know of a simple work around. I have looked at this thread http://stackoverflow.com/questions/745341/can-ms-sql-views-have-primary-and-foriegn-keys but in my scenario, what is recommended is not applicable. If I could only have the view added to the Model.

  • CharacterType/ConfigurationType in vsprops

    - by Cthutu
    Hi, I've been using Visual Studio's property sheets for building my code and I have a useful hierarchy of sheets controlling the build settings, rather than having them in the vcproj files. This is great except for one thing. I can't seem to set properties in the Project Defaults section such as CharacterType and ConfigurationType. I tried using a VCConfiguration tool in the vsprops but to no avail: <Tool Name="VCConfiguration" ConfigurationType="4" /> Can anyone tell me how this is accomplished please?

  • Need PHP script to decompress and loop through zipped file.

    - by Jim H.
    I am using a fairly straight-forward script to open and parse several xml files that are gzipped. I also need to do the same basic operation with a ZIP file. It seems like it should be simple, but I haven't been able to find what looked like equivalent code anywhere. Here is the simple version of what I am already doing: $import_file = "source.gz"; $sfp = gzopen($import_file, "rb"); ///// OPEN GZIPPED data while ($string = gzread($sfp, 4096)) { //Loop through the data /// Parse Output And Do Stuff with $string } gzclose($sfp); What would do the same thing for a zipped file?

  • What is your favorite textmate plugin or bundle?

    - by John Duff
    Textmate is a great editor with lots of plugins and bundles, hoping to find a few more that will make Textmate even more useful. I personally can't live without Ack in Project (http://github.com/protocool/ack-tmbundle), the built in search for textmate is awful, ack in project does searches 100x faster. What's your favorite Textmate plugin or bundle and what makes it so great?

  • Emacs: annoying Flymake dialog box.

    - by baol
    Hello I have the following lines in my ~/.emacs.d/init.el (custom-set-variables '(flymake-allowed-file-name-masks (quote ( ("\\.cc\\'" flymake-simple-make-init) ("\\.cpp\\'" flymake-simple-make-init))))) (add-hook 'find-file-hook 'flymake-find-file-hook) When I open a cc/cpp file that has a Makefile with the following content in the same folder I get proper on-the-fly compilation and error reporting (Flymake will check the syntax and report errors and warnings during code editing) .PHONY: check-syntax check-syntax: $(CXX) -Wall -Wextra -pedantic -fsyntax-only $(CHK_SOURCES) The problem is that when I open a .cc file that has no corresponding Makefile i get an annoying dialog box that warns me about flymake being disabled for every file opened. Is there some hook I can use to disable that warning? Can you provide sample elisp code and explanation on how you found the proper hook?

  • Banning by IP with php/mysql

    - by incrediman
    I want to be able to ban users by IP. My idea is to keep a list of IP's as rows in an BannedIPs table (the IP column would be an index). To check users' IP's against the table, I will keep a session variable called $_SESSION['IP'] for each session. If on any request, $_SESSION['IP'] doesn't match $_SERVER['REMOTE_ADDR'], I will update $_SESSION['IP'] and check the BannedIPs table to see if the IP is banned. (A flag will also be saved as a session variable specifying whether or not the user is banned) Here are the things I'm wondering: Does that sound like a good strategy with regards to speed and security (would someone be able to get around the IP ban somehow, other than changing IP's)? What's the best way to structure a mysql query that checks to see if a row exists? That is, what's the best way to query the db to see if a row with a certain IP exists (to check if it's banned)? Should I save the IP's as integers or strings? Note that... I estimate there will be between 1,000-10,000 banned IP's stored in the database. $_SERVER['REMOTE_ADDR'] is the IP from which the current request was sent.

  • PHP job interview questions?

    - by Richard Knop
    Hello, I'm going to attend a job interview on Friday this week. It's an interview for a position of PHP programmer (the company doesn't do websites so I guess they just need somebody to administer their website). I'm expecting there will be more people at the interview and that we will be given some simple questions or tasks in PHP so they can choose. I'd like to ask if anybody has any experience with interviews like this, what should I be expecting? What are the most common questions or simple tasks/programs in PHP employers give to potential employees? Thanks.
