  • date enable disable

    - by Newbie
    I have an "add new product page" and I have a field in the database table "jos_stockmovement", "start_week" which contains data for the year and week. In my "Add New Product" page I have a field dropdown-list named "Start Week" which holds the year and week, for example, "2012/36". How do I disable the past week? I all I want to enable is the current week. Heres my code: <td colspan="99"> <%= fld.select :start_week, options_for_select( StockMovement.order("year DESC, week DESC").map { | val | [ "#{ val.year }/#{ val.week }", val.id ] }, :selected => @product.start_week ), :class => "ddl_SW" %> </td>

  • Google Maps KML Solution Validation

    - by user728584
    Google Maps newbie (GIS newbie), I'm looking at a solution to map an overlay (number of polygons) on-top of Google maps and wondered if using a KML file was a viable solution? Basically, I have a number of address (address data) that I will pass to our internal GIS system, the GIS system hands me back a KML file (one file with a number of different locations) and then I draw the polygon using the KML Layering options: https://developers.google.com/maps/documentation/javascript/layers Sound like a viable solution? Cheers

  • UIWebView EXC_BAD_ACCESS crash

    - by HARDWARRIOR
    I'm experiencing crashes of an app that uses UIWebView. Usually it's when page is not fully loaded and UIWebView is sent stopLoading selector. Or when UIWebView fully loaded page. I've got EXC_BAD_ACCESS. Stack looks like this: #0 0x95bb7688 in objc_msgSend #1 0x30a671db in -[UIWebView webView:decidePolicyForNavigationAction:request:frame:decisionListener:] #2 0x3024a10d in __invoking___ #3 0x30249ff8 in -[NSInvocation invoke] #4 0x358ab160 in HandleDelegateSource #5 0x302452c1 in CFRunLoopRunSpecific #6 0x30244628 in CFRunLoopRunInMode #7 0x32044c31 in GSEventRunModal #8 0x32044cf6 in GSEventRun #9 0x309021ee in UIApplicationMain #10 0x0000239c in main at main.m:13 for me most strange thing here is webView:decidePolicyForNavigationAction:request:frame:decisionListener: selector sent to UIWebView, because there is no such selector in UIWebView documentation! Only for Cocoa (not cocoa touch) WebView. I suspect that there is something wrong with UIWebView or its delegate. But I can't set breakpoint to watch them. Please advise how I can get more info in this situation.

  • Find Window At Location Using Carbon And Carbon Problems In 64-Bit Applications

    - by JxXx
    As I said in some questions today I´m looking for the way to get window or windowPart references at a certain location. Although I know I could use Cocoa for this purpose (I don´t know how to do it yet) I prefer (and probably need) to do this using Carbon because the entire application that needs this functionality is written in C++ but I´ve found many problems trying it. Does anyone get a valid windowPtr or windowRef using one of the following functions? FindWindow, MacFindWindow, HIWindowFindAtLocation or FindWindowOfClass I always get 0 as the windowRef or windowPtr that I´m looking for. What I´m doing wrong? Any ideas? It´s true that now if you want to create a 64-bit application for Mac OS X, you need to use Cocoa to implement its user interface because some APIs commonly used by Carbon applications are not available in 64-bit applications? Thank you. JxXx

  • Eclipse 3.5 switching tab is very slow

    - by n179911
    I am using eclipse 3.5 (cocoa build) on Macos 10.5 with Java 1.5.0.19. I just have 3 java files opened 1 files ~ 2000 lines the other 2 are ~ 700 lines. But when I switch from 1 file tab to another, eclipse takes a long time (~ 20 seconds) to switch to another tab. I have already change the eclipse.ini to more eclipse.ini -startup ../../../plugins/org.eclipse.equinox.launcher_1.0.200.v20090520.jar --launcher.library ../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx_1.0.0.v20090519 -product org.eclipse.epp.package.jee.product -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m -vmargs -Dosgi.requiredJavaVersion=1.5 -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -XX:MaxPermSize=512m -Xms128m -Xmx1024m -Xdock:icon=../Resources/Eclipse.icns -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts Is there any way to make eclipse 3.5 more speedy?

  • VB Project Template for Monobjc in MonoDevelop?

    - by Ira Rainey
    After installing Monobjc and playing around with the Monobjc Application Project under C# in MonoDevelop, I noticed that there is only an empty Monobjc project under the VB section. Obviously this template adds all the correct references but doesn't add the basic files for the application to run. I've tried creating a class with: Imports System Imports Monobjc Imports Monobjc.Cocoa Class Application Public Sub Main(Byval args() As String) ObjectiveCRuntime.LoadFramework("Cocoa") ObjectiveCRuntime.Initialize() End Sub End Class Obviously I'm not loading the NIB there either, as I haven't added that in either, but if I try to build this I get: /Source/VB_Sample/VB_Sample/<MyGenerator>(1,1): Error VBNC30420: Could not find a 'Sub Main' in ''. (VBNC30420) (VB_Sample) Where should I be putting the Sub Main? Also if I add in a xib file from IB, how do I generate the designer code for the partial AppDelegate class? Any help would be appreciated.

  • Whats the scope of c code within objective-c classes?

    - by roja
    I was reading up about bypassing objective-c's messaging to gain performance (irrelevant to this specific question) when i found an interesting bit of code: #import <Cocoa/Cocoa.h> @interface Fib : NSObject { } - (long long) cFib: (NSUInteger) number; @end @implementation Fib // c implementation of fib long long cFibIMP(NSUInteger number) { return (number < 3) ? 1 : cFib(number - 1) + cFib(number - 2); } // method wrapper for c implementation of fib - (long long) cFib: (NSUInteger) number { return cFibIMP(number); } @end My question is; when using c function, within an objective-c object, what scope is the c function (cFibIMP in this particular case) placed in? Does the objective-c class encapsulate the c function removing change of name-clash or is the c function simply dumped into the global scope of the whole objective-c program?

  • How to properly use CoreData validation & error framework ?

    - by Xav
    I've created a model in Xcode, and for various attributes I have minimum & maximum values defined and that are enforced by coreData at runtime. I'm using NSManagedObject validateValue:forKey:error to check for user input values. I was a bit disappointed to see that the localized error message is not specific, and I get a "The operation couldn't be completed. (Cocoa error 1620)" for too small values and a "The operation couldn't be completed. (Cocoa error 1610)" for too large values. It's written in the coreData documentation that "you can localize most aspects of a managed object model, including entity and property names and error messages". Unfortunately it's not very detailed on how you implement it for error messages. So How do you customize error message ? How do you localize them ? Is it possible to customize it in a way where it will mentioned the reference value ex: "Value should be lower than %@" or "Value should be higher than %@" ?

  • Google Chrome OS

    - by Piet
    It’s about time someone took this initiative: Google Chrome OS I especially like the following: Speed, simplicity and security are the key aspects of Google Chrome OS. We’re designing the OS to be fast and lightweight, to start up and get you onto the web in a few seconds. The user interface is minimal to stay out of your way, and most of the user experience takes place on the web. And as we did for the Google Chrome browser, we are going back to the basics and completely redesigning the underlying security architecture of the OS so that users don’t have to deal with viruses, malware and security updates. It should just work. I recently had the ‘pleasure’ witnessing several 60+ yr old friends and family (all respect for everyone in their 2nd or 3rd youth) buying their first pc, taking their first steps using a pc and the net. Have you ever seen the gazillions of little ‘useful’ tools that are installed on a new standard Vista pc or laptop ? This is like learning to drive a new car and being placed in an airplane cockpit. And all the messages one gets about virus/security checks, fingerprint nog being enrolled, trial period expiring (because half those really useful tools come with a trial period), … If I was in their shoes, being confronted with this as a total newbie, I guess I’d just give up pretty soon. As a matter of fact, I actually gave up on Vista on my work-laptop, it was driving me crazy. Thank god I was allowed to install XP. I’m a Linux user at home, and Vista was such a frustrating experience that Windows XP actually felt like breath of fresh air. And what are those people using? Email, browsing…. and maybe writing a little letter now and then or storing their photo’s if they have a digital camera. Actually (side note), I get the impression that hearing about facebook is a major motivator for the digital newbies to finally take the plunge, buy a pc and get on-line. And OK, we’ve seen initiatives like this before, but Google is a brand everyone knows… unlike Ubuntu, Debain or Mandriva. Google = God. If I was Microsoft I’d be wetting my pants knowing Google was about to release their own OS, without a doubt fully optimized to use their own on-line office suit. On the other hand, the old adage ‘no one ever got fired for choosing Microsoft’ still holds a lot of truth. I hope I’ll be able to give it a big thumbs up if a would-be pc-user asks me what kind of pc/OS they should go for in the near future. On the other hand, if I’d do that, I’m pretty sure a couple of weeks later I’d get a call asking how to install this game or photo editing tool they got from one of their Windows using friends… or that nifty photo-printer they just bought. But then, I also get those questions now from newbie Windows users. It takes a couple of years before Newbie pc users understand that some things just don’t work and aren’t worth the time trying to fix them. I’d just wish they’d go back to the shop when something doesn’t work. You also don’t let you mechanic friend try to fix a problem with your brand new car. But that’s another story… Wait and see…

  • Eclipse: Slow startup time

    - by ct2k7
    Hello, I've got Eclipse 3.6.1 on my MacBook Air (2010), and I'm getting slowish startup times. Well, slow, compared to my Desktop, which is somewhat less powerful and a few years old). The startup generally takes 15 seconds, and of this, 4 is spent just on the Eclipse splash screen, before Eclipse loads anything. No projects are open at startup. Here's a copy of my eclipse.ini. -startup ../../../plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar --launcher.library ../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx.x86_64_1.1.1.R36x_v20100810 -showsplash org.eclipse.platform --launcher.XXMaxPermSize 512m --launcher.defaultAction openFile -vmargs -Xms256m -Xmx512m -Xdock:icon=../Resources/Eclipse.icns -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -Dosgi.requiredJavaVersion=1.6 -Xverify:none -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -XX:+UnlockExperimentalVMOptions -XX:+AggressiveOpts -XX:+StringCache -XX:+UseFastAccessorMethods -XX:+UseLargePages -XX:LargePageSizeInBytes=4m -XX:AllocatePrefetchLines=1 -XX:AllocatePrefetchStyle=1 -Dide.gc=true The problem doesn't seem to be related to plugins - I've disabled the ones which I don't need, and regardless of this configuration or whether all of them are selected on startup, it only takes 1second to load the plugins. I'm running Eclipse 3.6.1 Cocoa x64 build (vanilla) with the Zend Studio plugin. The machine has 4GB RAM, an SSD with over 64% free space, 1.6GHz (4MB L2 Cache). OS is Mac OS X 10.6.6, latest Java available, 1.6. For comparison, my Desktop, an old P4 3GHZ (512K L2 Cache) with a 7200RPM drive, under 40% free space, Eclipse (same config) loads in under 7 seconds, consistently. Note, this one is a Windows machine, with latest Java installed.

  • Apache server doesn't create directory or file under www-data user [duplicate]

    - by Harkonnen
    This question already has an answer here: What permissions should my website files/folders have on a Linux webserver? 4 answers very newbie to Apache here I installed Apache 2.4 on my Arch server where I installed newznab (a newsgroups indexer). I have noticed that all files newznab needs to create are created under my login user, and not apache default user (www-data). I read here that it's bad security practice to allow www-data to write files. I agree. But as an apache newbie, I would like to know where (in the httpd.conf I suppose ?) the user allowed to write files can be configured, because I want another account to be allowed to write files instead of my main account.

  • Moving a file using PuTTY

    I am newbie struggling to move a file on a Linux VPS using PuTTY. I can log in with a user in PuTTY at this point I can navigate to see the file I wish to move (~/servers/apache-solr-3.6.2/example/webapps/solr.war). By using cd .. a couple of times from the directory I begin at when I first log in to PuTTY I can then navigate to the location I wish to move the file to: usr/local/jakarta/apache-tomcat-5.5.36/webapps/ I know that I need to use cp to copy the file and have tried variations on: cp ~/servers/apache-solr-3.6.2/example/webapps/solr.war usr/local/jakarta/apache-tomcat-5.5.36/webapps However each time I get 'No such file or directory' I have tried excluding the ~/ and the start and I have tried specifying solr.war at the end of the command. Please excuse the newbie question, but I would really appreciate some advice on what I am doing wrong here.

  • Back up Linux environment

    - by joesavage
    I'm currently in the process of installing a bunch of stuff I need and getting setup my Linode that I recently purchased. Being a Linux newbie, I'm doing pretty well - but one small mistake can screw everything up for me. I've currently got apache2 and some other things successfully installed and setup how I want them, and DO NOT want this to be ruined by some newbie mistake. What is the easiest way to backup the actual environment itself so that I can restore the backed up environment (with apache2 and things fully working) if I mess up?

  • Unable to install Win XP nor Win 7 after installing Ubuntu 11.1

    - by Pablo C. Garcia
    I'll try to make this scenario as clear as possible. Laptop Specs HP dv6-2189la: 500 HDD 4GB Ram Intel i7 Personal Specs - Linux newbie running for the first time. Quite confused :( I had Windows 7 x64, decided to start fresh new so I planned on formatting. Since I use it for work and didn't require it for another week, I didn't rush into installing Win 7 immediately as I wanted to try Ubuntu for quite a while. 1) Downloaded Ubuntu 11.1 2) Burned ISO to CD 3) Installed Ubuntu using the full HDD of 500GB erasing Win7 4) Ubuntu ran awesome (especially for me being a Linux Newbie from scratch) I used Ubuntu for a while, but now I need to get back to work with Win 7. Tried running the installation CD for Win 7 and it just skips to Ubuntu without loading. Checked BIOS, tried other discs, even tried the disc on another computer and it works. Since that didn't work, I tried running Win XP. This CD does load, it starts loading files, drives, kernel, blah blah and before even getting to install it Blue screens with error 0x0000007b. I already used Gparted and created up to 250 GB space for Windows. Formatted to NTFS. I really don´t know what do now. I've tried almost everything I know within my knowledge. I could say I'm an advanced PC user, but I bumped into the Linux wall starting from scratch. All suggestions will be appreciated. Thanks!

  • ubuntu 11.10 foreman error

    Most of the newcomers in programming start with basic projects to start with programming. Most of the C++ progammers spend some time with puzzles and contests but this is not always helpful. Sometimes you've to spend some time on real projects. Starting your own open source project could be a problem in self-learning for newbie cause of lack of mentors and peers who can't look at your code and give suggestions. Open source projects can solve this problem, some projects could be best suited for new programmers. Besides everybody is newbie at some point. So i'll try and make this question a bit from beginners perspective. I tried few questions on stack overflow before asking this like How do i join & Bare minimum you need and how to get involved with open source and what level of programming etc. But this is not helping me when it comes to self-evaluating with skills. How to find that out ? How can i check what it takes to join open source project and am i really that comfortable with huge source code etc. My question is when to consider yourself comfortable joining open source programming ? I mean how will you test yourself that you're ready to take burden of big/small projects of open source ? how will you test yourself to see if you could work with version control/other programmers/tight schedule etc ?
