• Issues with SharePoint 2010 Development

  - by Rahul Soni

  I am planning to use my laptop for SharePoint 2010 development and I have only 4 GB RAM which is not even upgradable. Just because of RAM constraint, my VS 2010 keeps crawling if I try to run it along with SharePoint 2010 on the same machine. Hence, I've reformatted my machine and looking for alternate solutions until I get a new laptop. Currently, I have installed VS 2010 ONLY on my laptop and wanted to create an empty SharePoint project. Once done with my project, I want to deploy it on a different machine (which is a 4GB RAM machine as well, but contains only SharePoint 2010). I thought this will work and give me a bit of breather if everything is configured well. Unfortunately, when I tried creating a new SharePoint Empty Project in VS 2010, it says... A SharePoint server is not installed on this computer. A SharePoint server must be installed to work with SharePoint projects. Is there a way out?

• Why doesn't this UIButton show its text label?

  - by Dan Ray

  Everything about this UIButton renders great except the text that's supposed to be on it. NSLog demonstrates that the text is in the right place. What gives? UIButton *newTagButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [newTagButton addTarget:self action:@selector(showNewTagField) forControlEvents:UIControlEventTouchUpInside]; newTagButton.titleLabel.text = @"+ New Tag"; NSLog(@"Just set button label to %@", newTagButton.titleLabel.text); newTagButton.titleLabel.font = [UIFont systemFontOfSize:17]; newTagButton.titleLabel.textColor = [UIColor redColor]; CGSize addtextsize = [newTagButton.titleLabel.text sizeWithFont:[UIFont systemFontOfSize:17]]; CGSize buttonsize = { (addtextsize.width + 20), (addtextsize.height * 1.2) }; newTagButton.frame = CGRectMake(x, y, buttonsize.width, buttonsize.height); [self.mainView addSubview:newTagButton];

• Help Me Understand C++ Header files and Classes

  - by JamesW

  OK, So I am trying to transition from intermediate Delphi to C++ Object Oriented programing. I have read Ivar Horton's book on visual C++ 2010. I can pull off the simple console applications no problem. I get the language itself (kinda). Where I am struggling is with headers and classes. I also understand what header files and classes do in general. What I am not getting is the implementation when do I use a header or a class? Do I need to create classes for everything I do? Do my actual work functions need to be in header files or in CPP files? I'm lost on the proper uses of these and could use some real world guidance from more experienced programmers. I am trying to transition to windows applications using the MFC if that is helpful.

• how to tell Rails RSpec that spec is "type helper"

  - by equivalent8

  I wrote *simple_form* input extension that is located in app/inputs/something_input.rb I'm trying to write RSpec for this. When I put this spec inside spec/helpers/application_helper_spec.rb everything was working without single problem. # spec/helpers/application_helper_spec.rb require 'spec_helper' describe ApplicationHelper do it do helper.simple_form_for @foo,:method=>'get', :url=>helper.users_path do |f| f.input :created_at, :as =>:custom_datepicker end.should =~ /something/ end end Now I'm trying to move that spec to spec/inputs/something_input_spec.rb so it will be similar name path. # spec/imputs/something_input_spec.rb require 'spec_helper' describe SomethingInput do it do helper.simple_form_for @foo,:method=>'get', :url=>helper.users_path do |f| f.input :created_at, :as =>:custom_datepicker end.should =~ /something/ end end # #ERROR: undefined local variable or method `helper' for #<RSpec::Core::ExampleGroup the thing I want to tell RSpec to threat this file as type helper spec, so I will have helper method availible with all the RSpec::Rails::HelperExampleGroup functionality ... how can I do that ?? I was trying to extend/include it with RSpec::Rails::HelperExampleGroup nothing seems to work

• How to force asp.net GridView control to wrap first row within <thead> </thead> tags

  - by burak ozdogan

  Hi, I want to use Christian Bach's tableSorter client-side table sorting jQuery plugin with my asp.Net GridView control. But the problem is, in the documentation it writes: tablesorter works on standard HTML tables. You must include THEAD and TBODY tags: And unfortunately asp.net renders my GridView only with tags and header row stays within as the 1st row. I have tried: dgvRate.HeaderRow.TableSection = TableRowSection.TableHeader; after calling .DataBind(); It only helped to have <TH></TH> within the header . But still everything is inside <tbody> Can I accomplish this, I mean moving my 1st row from <tbody></tbody> to <thead></thead> ? I do not want to add it manually on PreRender stage; I am sure this could be handled much simpler, isn't it? thanks

• Service Contracts with Message causes duplicate proxy classes

  - by jaklucky

  Hi, I have a service contract with Message as shown below. [OperationContract] Message MyMethodWithMessage(Message myMsgParam); Everything works fine. I could host my services. But when I try to create proxies through "Add Service References", I am getting the duplicate proxy classes. If I take out the above OperationContract and re run my services and try to create proxies, then "Add Service References" does not provide duplicate proxies. I am really confused about this!!! Any help is greatly appreciated... Thank you, Suresh

• gvim "open in new window" should change directory to the one of the current file

  - by Flavius

  Hi I'm working in gvim with sessions and tabs, and everything works great. However there is something that is bothering me. Say I have two files open: /A/B/foo.ext and /C/D/E/bar.ext, the latter being opened last. Now say I want to open /A/B/foobar.ext. I have to go through the hassle of navigating upwards to / and from there to /A/B. I would like to simply change my active tab to /A/B/foo.ext and have gvim automatically change its active directory to /A/B/, so that when I want to open /A/B/foobar.ext with /A/B/foo.ext being active, I'm already in the right CWD. This would be very time-saving if you work with two different projects at a time and need to switch back and forth between the two. Is there any such script that does just that? Thanks.

• Python / Django : emulating a multidimensionnal layer on a mySql database

  - by Sébastien Piquemal

  Hi, I'm working on a Django project where I need to provide a lot of different visualizations on the same data (for example average of a value for each month, for each year / for a location, etc ...). I have been using OLAP database once in college, and I thought that it would fit my needs, but it appears that it is much to heavy for what I need. Actually the volume of data is not very big, so I don't need any optimization, just a way to present different visualizations of the same data without having to write 1000 times the same code. So let's recap : I need a python library : to emulate a multidimensional database (OLAP style would be nice because I think it is quite convenient : stat structure, and everything) non-intrusive, because I can't modify anything on the existing mysql database easy-to-use, because otherwise there's no point in replacing some overhead by another.

• Using javax.script or Rhino to run javascript in Java with browser context (e.g. envjs)?

  - by Shane

  I am trying to run Protovis javascript from a Java program using javax.script: ScriptEngineManager factory = new ScriptEngineManager(); ScriptEngine engine = factory.getEngineByName("JavaScript"); engine.eval(new java.io.FileReader("protovis-d3.1.js")); In order to run this, the JavaScript engine needs to have all the context of a web browser. The best option for this seems to be envjs. Unfortunately it seems that the version of Rhino included in the JVM isn't up to date and doesn't include everything that's necessary for envjs. Has anyone had any success working with a browser context from javax.script, or am I missing something? This is related to this question: "Can I create a ‘window’ object for javascript running in the Java6 Rhino Script Engine".

• Symfony 1.4: Is it possible to prevent escaping of a redirect URL?

  - by Tom

  Hi, If I do a redirect in action as normal: $this->redirect('@mypage?apple=1&banana=2&orange=3'); ... Symfony produces the correct URL: /something/something?apple=1&banana=2&orange=3 However, the following gets escaped for some bizarre reason: $string = 'apple=1&banana=2&orange=3'; $this->redirect('@mypage?'.$string); ... and the following URL is produced: /something/something?apple=1&amp;banana=2&amp;orange=3 Is there a way to avoid this escaping and have the ampersands appear correctly in the URL? I've tried everything I can think of and it's driving me mad. I need this for a situation where I'm pulling a saved query as a string from the database and would just like to latch it onto the URL. I'm aware that I could generate an array from the string and then generate a brand new URL from the array, but it just seems like a lot of overhead because of this silly escaping. Thanks.

• What causes subprocess.call to output blank file when attempting db export with mysqldump?

  - by caldazar

  I am having some problems using subprocess.call to export a database using mysqldump. I'm using Python 3.1 installed on Windows 7. from time import gmtime, strftime import subprocess DumpDir = "c:/apps/sqlbackup/"; DumpFile = "mysqldump-" + strftime("%Y-%m-%d-%H-%M-%S", gmtime()) + ".sql"; params = [r"mysqldump --user root --password=mypassword --force --flush-privileges --compress --comments mydatabase --result-file=" + DumpDir + DumpFile]; subprocess.call(params, shell=True); The above code causes a blank file to be created in the DumpDir. I've tried getting python to print the command so I can test it via the CMD prompt using: print(subprocess.list2cmdline(params)); If I paste the output to the CMD prompt and execute it, everything works fine. Any ideas? I'm new to Python, so I am sure the answer is simple but I've tried so many variations to get this working that I just can't figure this out.

• How to break a series of git commits into patches for submission to another project

  - by krosenvold

  So I've been bashing away at my favorite open source project for quite some time, and It's time for submitting issues with patches back. I have to regroup my commits more or less fully, and hopefully extract some pieces of code that can function as distinct patches to avoid code bombing. Currently I usually do something like this: rebase/squash everything to one commit since the old ones often don't make sense as patches undo that commit start adding stuff that I think fits to one commit, using add/add -i commit stash the rest test that commit re-apply the stash and start from 3 until all is accounted for It works, but is there a better way ?

• F5 irule with RESTful services

  - by Kyle Hayes

  I'm trying to come up with a rule on our F5 to direct traffic to our Tomcat server appropriately. We are deploying separate WAR files for each RESTful service. So, we would like to have the following URIs as an example: /services/quiz/01234/ /services/user/54321/ Where 'quiz' and 'user' are quiz.war and user.war respectively. We want to direct the traffic at the F5 level for /services/ to be the root and the rest of the URI to be directed to the Tomcat server. How do we accomplish this? Edit The browser url for a resource would look like http://www.domain.com/services/quiz/01234/ I want BIG-IP to send the request to tomcat as http://tomcatserver:8080/quiz/01234/ so basically remove /services and append everything after it to the tomcat domain. I would think this would be an easy regex, right?

• Accidentally deleted /opt/local/bin without backup. Any help?

  - by Aaron

  Hi all, I'm on a Mac OS X 10.5.8 I was recently uninstalling mysql5 from /opt/local/bin. I typed: rm -rf /opt/local/bin mysql* instead of rm -rf /opt/local/bin/mysql* This deleted my entire /opt/local/bin directory which puts me in a bit of a bind. Is there any way to recover these files? If not, I have a friend that is using a similar set of programs, would it be possible to use the contents of his folder? If I end up needing to re-install everything in this folder, what is the best way to go about doing this? Thanks in advance!

• Too many open connections... Did I mess up something?

  - by Legend

  I am developing a plugin (for a Bittorrent client named Azureus programmed in Java) that lets me add peers into the current list from which it is downloading. Everything was working fine until yesterday when I started getting these weird errors: DEBUG::Thu Apr 15 10:45:40 CET 2010::org.gudy.azureus2.core3.peer.impl.control.PEPeerControlImpl::addPeer::795: Injected peer 90.35.126.126:33064 was not added - Too many connections DEBUG::Thu Apr 15 10:48:40 CET 2010::org.gudy.azureus2.core3.peer.impl.control.PEPeerControlImpl::addPeer::795: Injected peer 80.25.126.126:33064 was not added - Too many connections DEBUG::Thu Apr 15 10:52:40 CET 2010::org.gudy.azureus2.core3.peer.impl.control.PEPeerControlImpl::addPeer::795: Injected peer 90.35.126.126:33064 was not added - Too many connections I am thinking I messed up something with the TCP sockets. Does anyone know why this could be happening?

• Finding matches between multiple JavaScript Arrays

  - by Chris Barr

  I have multiple arrays with string values and I want to compare them and only keep the matching results that are identical between ALL of them. Given this example code: var arr1 = ['apple', 'orange', 'banana', 'pear', 'fish', 'pancake', 'taco', 'pizza']; var arr2 = ['taco', 'fish', 'apple', 'pizza']; var arr3 = ['banana', 'pizza', 'fish', 'apple']; I would like to to produce the following array that contains matches from all given arrays: ['apple', 'fish', 'pizza'] I know I can combine all the arrays with var newArr = arr1.concat(arr2, arr3); but that just give me an array with everything, plus the duplicates. Can this be done easily without needing the overhead of libraries such as underscore.js? (Great, and now i'm hungry too!) EDIT I suppose I should mention that there could be an unknown amount of arrays, I was just using 3 as an example.

• SSIS - Can I get the column schema for a flat file source from a database?

  - by Steve Clement

  We receive a nightly data export from a vendor in the form of about 10 tab-delimited flat file without column headers. In addition, the vendor provides us with the SQL scripts for the database tables so that we can import the files into our system. Unfortunately, the vendor recently changed the schema for the flat files. Each file has upwards 150 columns, and having to go through the DB schema and adjust column types on a Flat File Data Source in SSIS is extremely time consuming, not to mention a royal pain. Since I know the file data layout in the database schema, is there any way I can dynamically pull that into a Flat File source to set the columns correctly? Or am I just stuck with manually setting everything?

• Java - Circular Garbage Collection

  - by aloh

  A <- B <- C <- D <- A... // A is firstNode, D is lastNode if ( length == 1 ) { firstNode = null; lastNode = null; firstNode.next = null; firstNode.prev = null; } else { Node secondNode = firstNode.next; Node secondToLast = lastNode.prev; firstNode.next = null; firstNode.prev = null; lastNode.next = null; lastNode.prev = null; secondNode.prev = null; secondToLast.next = null; firstNode = null; lastNode = null; } That should send everything in between as candidates for garbage collection, I hope?

• DLL response is to slow in Visual Studio

  - by magsto

  Hi, I use a 3rd party DLL in my VB.NET project (VS2005) that responds to slow and give wrong values in debug mode. In run-time mode everything works as expected. I do understand that there are something going on in the debug mode which makes the DLL communication slow. This behavior makes it hard to debug the application correctly. Is there any way to force VS to communicate with the DLL in "run-time" mode during debugging but let the rest of the project be in control of the debugger?

• Program seems to get stuck ?

  - by Frank

  I have a Java program, I did some change and the strange thing is no matter what I do now, it will output the same result before my change, I looked into my system (Windows Vista), and clicked on "Generate a system health report", the result says : Symptom : A service is reported as having an unexpected error code Cause : One or more services has failed. The service did not stop gracefully, suggesting the service may have crashed or one of its components stopped in an unsupported way. Details : Service exited with code not equal to 0 or 1077 Resolution : Restart the service It doesn't say which service, and I defragmented my drives a few times, it still gave me the same report. I also checked my memory, it says no problem with ram. Everything else is ok, I re-started the windows a few times, got more free space on my C: drive, yet the Java program is still not responding to my new changes, unless I intentionally make a mistake, it gives me compile error, but if it can compile successfully, it still gives me the results before the change. What can I do to fix this ? Frank

What's going on? .NET shouln't be portable? How to solve these exceptions?
