• WPF with code only

  - by rwallace

  I've seen a lot of questions about the merits of WPF here, and essentially every answer says it's the bee's knees, but essentially every answer also talks about things like XAML, in many cases graphic designers and Expression Blend etc. My question is, is it worth getting into WPF if you're a solo coder working in C# only? Specifically, I don't have a graphic designer, nor any great talent in that area myself; I don't use point-and-click tools; I write everything in C#, not XML. Winforms works fine in those conditions. Is the same true of WPF, or does it turn out that important functions can only be done in XAML, the default settings aren't intended for actual use and you have to have a graphic designer on the team to make things look good, etc., and somebody in my position would be better off to stick to Winforms?

  I whould like this simple rewrite rule: /somefolder/mypage.aspx?myid=4343&tab=overview to be redirected to: /folder/4343/overview/ I looked for some solutions and none actually worked.. I tried: rewrite ^/somefolder/mypage.aspx?myid=(.*)&tab=overview$ /folder/$1/overview permanent; and rewrite ^/somefolder/mypage\.aspx\?myid=(.*)&tab=overview$ /folder/$1/overview permanent; What am I doing wrong?

• How can I split a formula into multiple lines in OpenOffice calc?

  - by cherouvim

  I have this simple formula: =CONCATENATE("foo";"bar") which renders foobar on the cell. How can I lay this formula in multiple lines in the same cell? I'd like to be able to do something like the following but it doesn't work as the newline in the cell forbids the formula from being executed: =CONCATENATE("foo"; "bar") The reason I'm asking is because I have huge formulas an I need to format them (using newlines and a bit of indentation) for readability. thanks

• Excel 2007 How To Reference A Seperate Cell In WS1 From A Common Cell In WS2

  - by Bob Sampson

  I have a simple file with two worksheets in. In the first worksheet (a product list) are a number of columns, including Product Code and Product Description. In the second worksheet (dispatches in January), I have Product Code. I need to insert a new column with the associated Product Description field completed based on the relevant line from the first worksheet. I'm sure this is very easy, but its not something I've done before. Thank you

• Firefox 17 and CSS borders based triangles = crap

  - by Adeher

  Like many front-end devs, I've been using the border trick to render triangles in CSS. http://apps.eky.hk/css-triangle-generator/ this generator helps with the technique. Today, like every week (almost), the Firefox team released a new version without any clear changelog on the rendering engine. Now we can see an ungraceful gray border around those triangles. I haven't found a trick to get rid of it yet. On top of that, before Firefox 17, when people were complaining about how aliased those triangles looked, an additional trick was to set the border-style property to "dashed" instead of solid. Using firebug on the triangle generator, you can quickly see how it shows up now, and cry yourself to death. I hope a more brillant front-end dev than myself will find a fix for this and share it here. Thanks

• Firefox addin to "dim" a page

  - by Sean

  Hi, this is simple - I have a page opened all the time in FF, and don't want others passing by to see immediately the page. Is there a plugin that would allow to "dim" the page, unless you over it with a mouse or set focus on window? The idea is similar to laptops screen dimming. Thanks.

• clear IP address of Ethernet interface

  - by jackhab

  What is the Linux command to clear IP address of an interface without bringing it down and/or restarting network services. Seems strange ifconfig is able to change IP address but has no option to clear it, or am I wrong? EDIT:As simple as ifconfig eth0 0.0.0.0. They should have put it in the man

• How to process requests twice in Apache

  - by Pieter

  In order to perform realistic tests for a new backend server, I'd like to process all Apache requests twice. So simply handle all the live requests with the old server, as it's done right now, but then also 'duplicate' the requests to a different virtual host, where the new backend is deployed, which will process the request and log the response. What's the best / most simple way to achieve this in Apache? (the backend is a FastCGI process)

• preserving history when using mercurial ontop of clearcase

  - by Arthur Ulfeldt

  I work in a ClearCase shop and CC does a good job of integrating the team's work though our code review process prevents me from using it to track my daily changes. Creating an hg repository on top of my CC view works really well. I can track my changes and easily make backups on the file server, produce diffs for people etc. This is all well and good until I move to a new CC view and have to leave my history behind. I would love to be able to ?pull? my previous history in and have everything that's different in the new view show up as the latest change set.

• Moving multiple folders all at once in Outlook

  - by Luke

  Constantly at my shop, we are moving Outlook (or other email program) files between computers or Windows Installations, and sometimes, people have HUNDREDS of folders. Is there a quick way to move ALL the folders from multiple data files (*.PST) into one single file, without dragging each and every folder? No, I don't want to move the Inbox folder into the other Inbox folder for the quick move, I want something simple like selecting all folders and moving that way. Does such a method exist in any version of Outlook?

• Injecting EntityManager Vs. EntityManagerFactory

  - by SB

  A long question, please bear with me. We are using Spring+JPA for a web application. My team is debating over injecting EntityManagerFactory in the GenericDAO(a DAO based on Generics something on the lines provided by APPFUSE, we do not use JpaDaosupport for some reason) over injecting an EntityManager. We are using "application managed persistence". The arguments against injecting a EntityManagerFactory is that its too heavy and so is not required, the EntityManager does what we need. Also, as Spring would create a new instance of a DAO for every web request(I doubt this) there are not going to be any concurrency issues as in the same EntityManager instance is shared by two threads. The argument for injecting EFM is that its a good practice over all its always good to have a handle to a factory. I am not sure which is the best approach, can someone please enlighten me? SB

• C# Code Smells. What are the most common and how to fix them?

  - by Carlos Loth

  Hi, One thing I'd like to hear from you guys is what are the code smells that you see most often happen on C# code and how to fix them. I'm working on defining a code-review process for my team and I'd like to include a section with the most common C# code smells and a possible fix for each of them. I'd like the assistance of the community on that, so others can reuse this list for further reference. What are the most common smells you have seen on C# code? How did you fix them?

• Aldon and .Net Development

  - by David Stratton

  I'm looking for feedback from .Net developers who have experience with Aldon as a lifecycle management platform. We're seriously considering using Aldon for lifecycle management including source control, automated builds, etc. I know there are a lot of other options out there, but ours is primary an AS/400 shop (with AS/400 programmers outnumbering .Net developers 6 to 1), and Aldon is used already by our iSeries team. The benefit we're looking for is having one lifecycle management suite. Basically, I'm looking for opinions from people who have used Aldon and another set of tools (perhaps TFS, or a combination of SVN, Cruise Control, etc). If you've worked with both, do you have a recommendation on whether this is a good idea, or a bad idea? It's obviously a big choice, so any feedback would be helpful.

• iPhone write to file (alternative directory)

  - by strider2k

  New to iPhone 3.2, Apple introduced File-Sharing support. Details can be found at https://developer.apple.com/iphone/library/releasenotes/General/WhatsNewIniPhoneOS/Articles/iPhoneOS3_2.html#//apple_ref/doc/uid/TP40009337-SW1 . Now, most examples floating around in the web demonstrates writing to the documents directory. What if I want to write files from my app but I don't want the user to be able to see it via iTunes? I'm looking at the Files and Networking section of the iPhone OS Programming Guide and I'm unsure what would be a good alternative to the documents directory for writing files to hide from the user and not be rejected by Apple's review team.

Has anyone tried a similar project and have any advice? For instance a sample entry would read: Can't connect to the internet 1) Check physical connection to internet (cable attached to your computer) 2) check wireless connection 3) ping dns server 4) if Ping fails call Tech Support

• how to deal with a static analyzer output

  - by Jim

  We have started using a static analyzer (Coverity) on our code base. We were promptly stupefied by the sheer amount of warnings we received (its in the hundreds of thousands) , it will take the entire team a few mounts to clear them all (obliviously impossible). the options we discussed so far are 1) hire a contractor to sort out the warning and fix them - he drawback: we will probably need very experiences people to do all these modifications, and no contractor will have required understanding of the code. 2) filter out the warning and deal only with the dangerous ones - the problem here is that our static analysis output will always be cluttered by warning making it difficult for us to isolate problems. also the filtering of the warning is also a major effort. either way, bringing our code to a state when the static analyzer can be a useful tool for us seems a monumental task. so how is it possible to work with the static analyzer without braining current development efforts into a complete stand still?

• MVVM and division of amongst multiple developers

  - by nlawalker

  Can anyone speak to the ease of dividing work amongst multiple developers when designing and building a medium- to large-complexity Silverlight or WPF application? My team is finding it difficult to cleanly split work when you've got, for example, a number of controls that provide different visualizations of a Model/ViewModel that's fairly complex and has a lot of properties and methods for interacting with data. It seems like a very big portion of the work ends up being the design and build of the Model/ViewModel, and much less inside each of the controls, which are naturally what are easy to ration out to multiple people.

• How does the os know which paramater to pass to /etc/init.d/

  - by iDev247

  I've been working with linux for a while but in a rather simple manner. I understand that scripts in init.d are executed when the os starts but how exactly does it works? How does the os know which paramater to pass to a script? To start apache I would do sudo /etc/init.d/apache2 start. If I run sudo /etc/init.d/apache2 it doesn't work without the start. How does the os pass start to the script?

• Code Signing Identity does not match in my keychain, for mac app store developing?

  - by larntin

  hi, 1, I already download the "Apple Worldwide Developer Relations Certification Authority",and add it into my keychain. 2, My team leader already had created two Cers for Mac App store developing, I download and add it into my keychain. 3, I used two methods to sign my add, but failed all. First, add code sign section in my .xcodeproj(3.2.5). Second, I used script: productbuild --component ./bin/MAS_Release/MyApp.app /Applications --sign "3rd Party Mac Developer Application: My Company Co., Ltd." --product ./src/MyApp/MyApp-Info.plist MyApp.pkg But it failed with information: Code Signing Identity '3rd Party Mac Developer Application: My Company Co., Ltd.' does not match any valid, non-expired, code-signing certificate in your keychain. I observed that my certifications in keychain don't have small trangle. how make the small trangle absence?(when I'am importing the Cers from my Agent, it don't have the trangle absence)

• Working effectively unit tests / Anyone tried the in-assembly approach?

  - by CodingCrapper

  I'm trying to re-introduce unit testing into my team as our current coverage is very poor. Our system is quite large 40+ projects/assemblies. We current use a project named [SystemName].Test.csproj were all the test code is dumped and organised to represent the namespaces using folders. This approach is not very scalable and makes it difficult to find tests. I've been thinking about added a Tests folder to each project, this would put the unit tests "in the developers face" and make them easy to find. The downside is the Production release code would contain references to nunit, nmocks as well as the test code and test data.... Has anyone tried this approach? How is everyone else working with unit tests on large projects? Having a Tests project per "real" project/assembly would introduce too many new projs. Thanks in advance

• How to profile a silverlight application?

  - by rudigrobler

  Is their any profilers that support Silverlight? I have tried ANTS (Version 3.1) without any success? Does version 4 support it? Any other products I can try? Updated since the release of Silverlight 4, it is now possible to do full profiling on SL applications... check out this article on the topic At PDC, I announced that Silverlight 4 came with the new CoreCLR capability of being profile-able by the VS2010 profilers: this means that for the first time, we give you the power to profile the managed and native code (user or platform) used by a Silverlight application. woohoo. kudos to the CLR team. Sidenote: From silverlight 1-3, one could only use things like xperf (see XPerf: A CPU Sampler for Silverlight) which is very powerful to see the layout/text/media/gfx/etc pipelines, but only gives the native callstack.) From SilverLite (PDC video, TechEd Iceland, VS2010, profiling, Silverlight 4)
