  • Can't install plugins in Eclipse 3.5 (Galileo) on Ubuntu

    - by dfrankow
    Eclipse Version 3.5.2 Build id: M20100211-1343 Platform: Ubuntu 10.4 I go to install any new software Eclipse plugins (e.g., pydev, subclipse), and it gets to the 60% mark and stops. I wait for a long while and nothing happens. When I hit "cancel" a security warning comes up "Warning: You are installing software that contains unsigned content.." I click "OK" but it's too late because I've cancelled the installation already. It won't pop up until I hit "cancel". I've tried moving all the windows around, that security warning is not there. In previous incarnations of Eclipse, I've been able to click "OK" on that warning (no canceling) and all is well. I've also tried two JREs (Ubuntu's default openjdk and Sun's JDK 1.6.0_20). Is there some way to get that warning to come up, or even just have it always accept unsigned content? I've downloaded the zip of pydev and unzipped it into ~/.eclipse/org.eclipse.platform_3.5.0_155965261/ and Eclipse doesn't have Pydev when restarted, so manually installing plugins is also a pain. This is not my day. Yes, I see the other questions of this type and they don't seem to answer my problem.

  • Why does Internet Explorer break "pegman" display in Google Maps API v3?

    - by Chad
    On my site here, the SteetView control, aka "Pegman", works great under Firefox. Under IE (7 in this case, but tested on 8 as well - same result) it breaks the display of the pegman control. Here's my map code: var directionsDisplay; var directionsService = new google.maps.DirectionsService(); var map; directionsDisplay = new google.maps.DirectionsRenderer(); var milBase = new google.maps.LatLng(35.79648921414565, 139.40663874149323); var mapOpts = { streetViewControl: true, zoom: 12, center: milBase, mapTypeControlOptions: { style: google.maps.MapTypeControlStyle.DROPDOWN_MENU }, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map($("#dirMap").get(0), mapOpts); directionsDisplay.setMap(map); var basePoly = new google.maps.Polygon({ paths: [new google.maps.LatLng(35.724496338474104, 139.3444061279297), new google.maps.LatLng(35.74748750802863, 139.3363380432129), new google.maps.LatLng(35.75765724051559, 139.34303283691406), new google.maps.LatLng(35.76545779822543, 139.3418312072754), new google.maps.LatLng(35.767547103447725, 139.3476676940918), new google.maps.LatLng(35.75835374997911, 139.34955596923828), new google.maps.LatLng(35.755149755962755, 139.3567657470703), new google.maps.LatLng(35.74679090345495, 139.35796737670898), new google.maps.LatLng(35.74762682821177, 139.36294555664062), new google.maps.LatLng(35.744422402303826, 139.36346054077148), new google.maps.LatLng(35.74860206266584, 139.36946868896484), new google.maps.LatLng(35.735644401200986, 139.36843872070312), new google.maps.LatLng(35.73843117306677, 139.36174392700195), new google.maps.LatLng(35.73592308277646, 139.3531608581543), new google.maps.LatLng(35.72686543236113, 139.35298919677734), new google.maps.LatLng(35.724496338474104, 139.3444061279297)], strokeColor: "#ff0000", strokeOpacity: 0.8, strokeWeight: 2, fillColor: "#FF0000", fillOpacity: 0.35 }); basePoly.setMap(map); var marker = new google.maps.Marker({ position: new google.maps.LatLng(35.79648921414565, 139.40663874149323), map: map, title: "Ruby International" }); function calcRoute() { var start = new google.maps.LatLng(35.74005964772476, 139.37083393335342); var end = new google.maps.LatLng(35.79648921414565, 139.40663874149323); var request = { origin: start, destination: end, travelMode: google.maps.DirectionsTravelMode.DRIVING }; directionsService.route(request, function(result, status) { if (status == google.maps.DirectionsStatus.OK) { directionsDisplay.setDirections(result); } }); } The only real difference from my code and Google's code is that I use jQuery's document ready function instead of the body onload event to initialize my map. Can't imagine that's the cause though (works in v2 of the maps). Have I found a bug or is there something wrong in my code? Thanks in advance!

  • Can't install ruby-debug-ide on Windows 7

    - by Jack Allan
    I'm running netbeans 6.8 on windows 7 pro (x64) with the bitnami stack and I'm using ruby 1.8.7-p72. Note: I can't change the version of ruby I am using because I am working with a team, this is a college project and we have only 3 weeks left before we have to hand it in. Changing the version of ruby at this time would be too much work I think. I can't debug my code with the IDE. It says I must have the fast-debugger installed but I cannot install it. When I try through the gui I get the following message: Building native extensions. This could take a while... ERROR: Error installing ruby-debug-ide: ERROR: Failed to build gem native extension. "C:/Program Files/BitNami RubyStack/ruby/bin/ruby.exe" mkrf_conf.rb Building native extensions. This could take a while... Gem files will remain installed in C:/Program Files/BitNami RubyStack/ruby/lib/ruby/gems/1.8/gems/ruby-debug-ide-0.4.8 for inspection. Results logged to C:/Program Files/BitNami RubyStack/ruby/lib/ruby/gems/1.8/gems/ruby-debug-ide-0.4.8/ext/gem_make.out I have tracked the problem down to a gcc not being installed... I have installed cygwin but I'm not sure what I am doing and it's still not working... Anyone know how to fix this problem? (BTW- I have already done a lot of googling on this)

  • How do you Send More that 20 Parameters to a Stored Procedure Using ODP.Net?

    - by discwiz
    Switching from Microsofts Oracle Driver to ODP.NET version 10.2.0.100.

  • Building the Ultimate SharePoint 2010 Development Environment

    - by Manesh Karunakaran
    It’s been more than a month since SharePoint 2010 RTMed. And a lot of people have downloaded and set up their very own SharePoint 2010 development rigs. And quite a few people have written blogs about setting up good development environments, there is even an MSDN article on it. Two of the blogs worth noting are from MVPs Sahil Malik and Wictor Wilén. Make sure that you check these out as well. Part of the bad side-effects of being a geek is the need to do the technical stuff the best way possible (pragmatic or otherwise), but the problem with this is that what is considered “best” is relative. Precisely the reason why you are reading this post now. Most of the posts that I read are out dated/need updations or are using the wrong OS’es or virtualization solutions (again, opinions vary) or using them the wrong way. Here’s a developer’s view of Building the Ultimate SharePoint 2010 Development Rig. If you are a sales guy, it’s time to close this window. Confusion 1: Which Host Operating System and Virtualization Solution to use? This point has been beaten to death in numerous blog posts in the past, if you have time to invest, read this excellent post by our very own SharePoint Joel on this subject. But if you are planning to build the Ultimate Development Rig, then Windows Server 2008 R2 with Hyper-V is the option that you should be looking at. I have been using this as my primary OS for about 6-7 months now, and I haven’t had any Driver issue or Application compatibility issue. In my experience all the Windows 7 drivers work fine with WIN2008 R2 also. You can enable Aero for eye candy (and the Windows 7 look and feel) and except for a few things like the Hibernation support (which a can be enabled if you really want it), Windows Server 2008 R2, is the best Workstation OS that I have used till date. But frankly the answer to this question of which OS to use depends primarily on one question - Are you willing to change your primary OS? If the answer to that is ‘Yes’, then Windows 2008 R2 with Hyper-V is the best option, if not look at vmWare or VirtualBox, both are equally good. Those who are familiar with a Virtual PC background might prefer Sun VirtualBox. Besides, these provide support for running 64 bit guest machines on 32 bit hosts if the underlying hardware is truly 64 bit. See my earlier post on this. Since we are going to make the ultimate rig, we will use Windows Server 2008 R2 with Hyper-V, for reasons mentioned above. Confusion 2: Should I use a multi-(virtual) server set up? A lot of people use multiple servers for their development environments - like Wictor Wilén is suggesting - one server hosting the Active directory, one hosting SharePoint Server and another one for SQL Server. True, this mimics the production environment the best possible way, but as somebody who has fallen for this set up earlier, I can tell you that you don’t really get anything by doing this. Microsoft has done well to ensure that if you can do it on one machine, you can do it in a farm environment as well. Besides, when you run multiple Server class machine instances in parallel, there are a lot of unwanted processor cycles wasted for no good use. In my personal experience, as somebody who needs to switch between MOSS 2007/SharePoint 2010 environments from time to time, the best possible solution is to Make the host Windows Server 2008 R2 machine your Domain Controller (AD Server) Make all your Virtual Guest OS’es join this domain. Have each Individual Guest OS Image have it’s own local SQL Server instance. The advantages are that you can reuse the users and groups in each of the Guest operating systems, you can manage the users in one place, AD is light weight and doesn't take too much resources on your host machine and also having separate SQL instances for each of the Development images gives you maximum flexibility in terms of configuration, for example your SharePoint rigs can have simpler DB configurations, compared to your MS BI blast pits. Confusion 3: Which Operating System should I use to run SharePoint 2010 Now that’s a no brainer. Use Windows 2008 R2 as your Guest OS. When you are building the ultimate rig, why compromise? If you are planning to run Windows Server 2008 as your Guest OS, there are a few patches that you need to install at different times during the installation, for that follow the steps mentioned here Okay now that we have made our choices, let’s get to the interesting part of building the rig, Step 1: Prepare the host machine – Install Windows Server 2008 R2 Install Windows Server 2008 R2 on your best Desktop/Laptop. If you have read this far, I am quite sure that you are somebody who can install an OS on your own, so go ahead and do that. Make sure that you run the compatibility wizard before you go ahead and nuke your current OS. There are plenty of blogs telling you how to make a good Windows 2008 R2 Workstation that feels and behaves like a Windows 7 machine, follow one and once you are done, head to Step 2. Step 2: Configure the host machine as a Domain Controller Before we begin this, let me tell you, this step is completely optional, you don’t really need to do this, you can simply use the local users on the Guest machines instead, but if this is a much cleaner approach to manage users and groups if you run multiple guest operating systems.  This post neatly explains how to configure your Windows Server 2008 R2 host machine as a Domain Controller. Follow those simple steps and you are good to go. If you are not able to get it to work, try this. Step 3: Prepare the guest machine – Install Windows Server 2008 R2 Open Hyper-V Manager Choose to Create a new Guest Operating system Allocate at least 2 GB of Memory to the Guest OS Choose the Windows 2008 R2 Installation Media Start the Virtual Machine to commence installation. Once the Installation is done, Activate the OS. Step 4: Make the Guest operating systems Join the Domain This step is quite simple, just follow these steps below, Fire up Hyper-V Manager, open your Guest OS Click on Start, and Right click on ‘Computer’ and choose ‘Properties’ On the window that pops-up, click on ‘Change Settings’ On the ‘System Properties’ Window that comes up, Click on the ‘Change’ button Now a window named ‘Computer Name/Domain Changes’ opens up, In the text box titled Domain, type in the Domain name from Step 2. Click Ok and windows will show you the welcome to domain message and ask you to restart the machine, click OK to restart. If the addition to domain fails, that means that you have not set up networking in Hyper-V for the Guest OS to communicate with the Host. To enable it, follow the steps I had mentioned in this post earlier. Step 5: Install SQL Server 2008 R2 on the Guest Machine SQL Server 2008 R2 gets installed with out hassle on Windows Server 2008 R2. SQL Server 2008 needs SP2 to work properly on WIN2008 R2. Also SQL Server 2008 R2 allows you to directly add PowerPivot support to SharePoint. Choose to install in SharePoint Integrated Mode in Reporting Server Configuration. Step 6: Install KB971831 and SharePoint 2010 Pre-requisites Now install the WCF Hotfix for Microsoft Windows (KB971831) from this location, and SharePoint 2010 Pre-requisites from the SP2010 Installation media. Step 7: Install and Configure SharePoint 2010 Install SharePoint 2010 from the installation media, after the installation is complete, you are prompted to start the SharePoint Products and Technologies Configuration Wizard. If you are using a local instance of Microsoft SQL Server 2008, install the Microsoft SQL Server 2008 KB 970315 x64 before starting the wizard. If your development environment uses a remote instance of Microsoft SQL Server 2008 or if it has a pre-existing installation of Microsoft SQL Server 2008 on which KB 970315 x64 has already been applied, this step is not necessary. With the wizard open, do the following: Install SQL Server 2008 KB 970315 x64. After the Microsoft SQL Server 2008 KB 970315 x64 installation is finished, complete the wizard. Alternatively, you can choose not to run the wizard by clearing the SharePoint Products and Technologies Configuration Wizard check box and closing the completed installation dialog box. Install SQL Server 2008 KB 970315 x64, and then manually start the SharePoint Products and Technologies Configuration Wizard by opening a Command Prompt window and executing the following command: C:\Program Files\Common Files\Microsoft Shared Debug\Web Server Extensions\14\BIN\psconfigui.exe The SharePoint Products and Technologies Configuration Wizard may fail if you are using a computer that is joined to a domain but that is not connected to a domain controller. Step 8: Install Visual Studio 2010 and SharePoint 2010 SDK Install Visual Studio 2010 Download and Install the Microsoft SharePoint 2010 SDK Step 9: Install PowerPivot for SharePoint and Configure Reporting Services Pop-In the SQLServer 2008 R2 installation media once again and install PowerPivot for SharePoint. This will get added as another instance named POWERPIVOT. Configure Reporting Services by following the steps mentioned here, if you need to get down to the details on how the integration between SharePoint 2010 and SQL Server 2008 R2 works, see Working Together: SQL Server 2008 R2 Reporting Services Integration in SharePoint 2010 an excellent article by Alan Le Marquand Step 10: Download and Install Sample Databases for Microsoft SQL Server 2008R2 SharePoint 2010 comes with a lot of cool stuff like PerformancePoint Services and BCS, if you need to try these out, you need to have data in your databases. So if you want to save yourself the trouble of creating sample data for your PerformancePoint and BCS experiments, download and install Sample Databases for Microsoft SQL Server 2008R2 from CodePlex. And you are done! Fire up your Visual Studio 2010 and Start Coding away!!

  • pyQt4: QWidget subclass not responding to new setStyleSheet() background colour

    - by Ronny
    I am having an issue with PyQt4. I want to create a new widget within a window, and I want this widget to have a custom color. When i create a subclass of the QWidget class, and instantiate it, I am not able to change its background color through the setStyleSheet() function. When I instantiate a new QWidget object, I have no problems in changing its background color. But i dont want an ordinary QWidget object.I want to create my own subclass of QWidget. When i create a subclass of a QPushButton, I am also able to change its background color using the setStyleSheet() function. There are no error messages or warnings in the console window, it just refuses to work properly without any indication as to why. So what i would like to know is why is it that i can change the background color of a widget if i simply create a QWidget object, or a subclass of QPushButton, but not when i create a subclass of QWidget. And how can i therefore change the background color of an object that is a subclass of QWidget? Is it maybe something specific to the version of python or PyQt that i am using? Is it a bug in the library? or some flaw in the way that i am writing my code? I am using python 2.6.4 and PyQt4 Below is an example of the code that leads me to trouble. There are three widgets within the window one below the other. The parent widget is set with background color of green. The top widget is set to red, the middle one, is the subclass of QWidget, which should be blue, but it appears invisible because it takes on the color of the parent window for some reason. and the bottom widget is a subclass of QPushButton and is white. import sys from PyQt4 import QtGui, QtCore ################################################################################ #--------------------------------------------------------- CUSTOM WIDGET CLASS 1 class CustomWidget(QtGui.QWidget): def __init__(self, parent): QtGui.QWidget.__init__(self, parent) # some custom properties and functions will follow ################################################################################ #--------------------------------------------------------- CUSTOM WIDGET CLASS 2 class CustomWidget2(QtGui.QPushButton): def __init__(self, parent): QtGui.QPushButton.__init__(self, parent) # some custom properties and functions will follow ################################################################################ #----------------------------------------------------------- PARENT WIDGET CLASS class Parent(QtGui.QWidget): def __init__(self, parent=None): #---------------------------------------------------------- SETUP WINDOW QtGui.QWidget.__init__(self, parent) self.resize(500, 340) self.setStyleSheet("QWidget {background-color: #00FF00}") #-------------------------------------------------- SETUP DEFAULT WIDGET wid1 = QtGui.QWidget(self) wid1.setGeometry(10, 10, 480, 100) wid1.setStyleSheet("QWidget {background-color: #FF0000 }") #------------------------------------------------- SETUP CUSTOM WIDGET 1 wid2 = CustomWidget(self) wid2.setGeometry(10, 120, 480, 100) wid2.setStyleSheet("QWidget {background-color: #0000FF }") for i in dir(wid2): print i #------------------------------------------------- SETUP CUSTOM WIDGET 2 wid3 = CustomWidget2(self) wid3.setGeometry(10, 230, 480, 100) wid3.setStyleSheet("QWidget {background-color: #FFFFFF }") ################################################################################ #-------------------------------------------------------------------------- MAIN app = QtGui.QApplication(sys.argv) win = Parent() win.show() app.exec_()

  • Use the Twitter API to run a script every time I post a new tweet

    - by Mathias Bynens
    I have a PHP script on my server that I want to run every time I post a new tweet to Twitter. Is there a way to automate this? I could of course set up a cron job to run the script every five minutes, or run the script manually every time after tweeting, but neither of those is instant — and that’s exactly what I’m looking for. Is it possible to use the Twitter API to run a script / get a URL every time my timeline is updated?

  • Oracle TNS names not showing when adding new connection to sqldeveloper

    - by Americus
    Hello, I'm trying to connect to an oracle database with sqldeveloper. I've installed the .Net oracle drivers and placed the tnsnames.ora file at C:\Oracle\product\11.1.0\client_1\Network\Admin. I'm using the following format in tnsnames.ora. dev = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.XXX.XXX)(PORT = XXXX)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = idpdev2) ) ) In sqldeveloper, when I try to create a new connection, no tns names show up as options. Is there something I'm missing?

  • How Do I Prevent Rails From Treating Updated Nested Attributes Differently From New Nested Attribute

    - by James
    I am using rails3 beta3 and couchdb via couchrest. I am not using active record. I want to add multiple "Sections" to a "Guide" and add and remove sections dynamically via a little javascript. I have looked at all the screencasts by Ryan Bates and they have helped immensely. The only difference is that I want to save all the sections as an array of sections instead of individual sections. Basically like this: "sections" => [{"title" => "Foo1", "content" => "Bar1"}, {"title" => "Foo2", "content" => "Bar2"}] So, basically I need the params hash to look like that when the form is submitted. When I create my form I am doing the following: <%= form_for @guide, :url => { :action => "create" } do |f| %> <%= render :partial => 'section', :collection => @guide.sections %> <%= f.submit "Save" %> <% end %> And my section partial looks like this: <%= fields_for "sections[]", section do |guide_section_form| %> <%= guide_section_form.text_field :section_title %> <%= guide_section_form.text_area :content, :rows => 3 %> <% end %> Ok, so when I create the guide with sections, it is working perfectly as I would like. The params hash is giving me a sections array just like I would want. The problem comes when I want edit guide/sections and save them again because rails is inserting the id of the guide in the id and name of each form field, which is screwing up the params hash on form submission. Just to be clear, here is the raw form output for a new resource: <input type="text" size="30" name="sections[][section_title]" id="sections__section_title"> <textarea rows="3" name="sections[][content]" id="sections__content" cols="40"></textarea> And here is what it looks like when editing an existing resource: <input type="text" value="Foo1" size="30" name="sections[cd2f2759895b5ae6cb7946def0b321f1][section_title]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_section_title"> <textarea rows="3" name="sections[cd2f2759895b5ae6cb7946def0b321f1][content]" id="sections_cd2f2759895b5ae6cb7946def0b321f1_content" cols="40">Bar1</textarea> How do I force rails to always use the new resource behavior and not automatically add the id to the name and value. Do I have to create a custom form builder? Is there some other trick I can do to prevent rails from putting the id of the guide in there? I have tried a bunch of stuff and nothing is working. Thanks in advance!

  • Will .Net 4.0 include a new CLR or keep with version 2.0

    - by Rory Becker
    Will .Net 4.0 use a new version of the CLR (v2.1, 3.0) or will it stick with the existing v2.0? Supplementary: Is it possibly going to keep with CLR v2.0 and add DLR v1.0? Update: Whilst this might look like a speculative question which cannot be answered, the VS team appear to be releasing more and more info on VS10 and .Net 4.0 so this may very soon not be the case.

  • PackageMaker install script for rxtx

    - by vinzenzweber
    I am using PackageMaker to create an installer for my application. During installation I need to run a bash script to properly install rxtx, a JNI library for serial port communication. This library needs to have the directory /var/lock in place with user "root" and group "uucp". The installation script also needs to add the current user to the group "uucp" for the lib to be able to write to /var/lock. Now when I run my application installer the preinstall script is run as root. Therefore "whoami" returns root instead of the user who is actually running the installer. The result is that rxtx is not able to create lock files in /var/lock because the actual user was not added as a member to "uucp". How can I get the user while my script is run by the installer. Or is it better to set the permissions for /var/lock to a different group maybe? Any suggestions are welcome! !/bin/sh curruser=whoami logger "Setting permissions for /var/lock for user $curruser!" if [ ! -d /var/lock ] then logger "Creating /var/lock!" sudo mkdir /var/lock fi sudo chgrp uucp /var/lock sudo chmod 775 /var/lock MacOSX 10.5 and later use dscl if [ sudo dscl . -read /Groups/uucp GroupMembership | grep $curruser | wc -l = "0" ] then logger "Add user $curruser to /Groups/uucp!" sudo dscl . -append /Groups/uucp GroupMembership $curruser # to revert use: # sudo dscl . -delete /Groups/uucp GroupMembership $curruser else logger "GroupMembership of /var/lock not changed!" fi

  • CSS new line issues

    - by user328371
    Hi, I'm trying to create a breezebrowser template (used for generating image galleries locally, outputs HTML). I've taken the HTML from my wordpress template and managed to generate the following gallery http://uploads.peasyphotos.com/20100607t-candids/gallery/ but each image goes on a new line and i don't know why, i presume it's in the CSS. What should I be looking for in the CSS to try and stop this, or what can I put around my template code to disable the CSS for that part? Thanks
