• What is the best practice to segment c#.net projects based on a single base project

  - by Anthony

  Honestly, I can't word my question any better without describing it. I have a base project (with all its glory, dlls, resources etc) which is a CMS. I need to use this project as a base for othe custom bake projects. This base project is to be maintained and updated among all custom bake projects. I use subversion (Collabnet and Tortise SVN) I have two questions: 1 - Can I use subversion to share the base project among other projects What I mean here is can I "Checkout" the base project into another "Checked Out" project and have both update and commit seperatley. So, to paint a picture, let's say I am working on a custom project and I modify the core/base prject in some way (which I know will suit the others) can I then commit those changes and upon doing so when I update the base project in the other "Checked out" resources will it pull the changes? In short, I would like not to have to manually deploy updated core files whenever I make changes into each seperate project. 2 - If I create a custom file (let's say an webcontrol or aspx page etc) can I have it compile seperatley from the base project Another tricky one to explain. When I publish my web application it creates DLLs based on the namespaces of projects attached to it. So I may have a number of DLLs including the "Website's" namespace DLL, which could simply be website. I want to be able to make a seperate, custom, control which does not compile into those DLLs as the custom files should not rely on those DLLS to run. Is it as simple to set a seperate namespace for those files like CustomFiles.ProjectName for example? Think of the whole idea as adding modules to the .NET project, I don't want the module's code in any of the core DLLs but I do need for module to be able to access the core dlls. (There is no need for the core project to access the module code as it should be one way only in theory, though I reckon it woould not be possible anyway without using JSON/SOAP or something like that, maybe I am wrong.) I want to create a pluggable environment much like that of Joomla/Wordpress as since PHP generally doesn't have to be compiled first I see this is the reason why all this is possible/easy. The idea is to allow pluggable themes, modules etc etc. (I haven't tried simply adding .NET themes after compile/publish but I am assuming this is possible anyway? OR does the compiler need to reference items in the files?)

• Reading a file used by another process

  - by Tophe

  I know this has been up for discussion but I can't find an answer to my specific problem. I am monitoring a text file that is being written to by a server program. Every time the file is changed the content will be outputted to a window in my program. The problem is of course, that I can't use the Streamreader on the file as it is being "used by another process". Also setting up a Filestream with ReadWrite won't do any good since I cannot control the process that is using the file. However... You CAN open the file in notepad, so somehow it must be possible to access it even though the server is using it. Is there a good way around this? Should I monitor the file, make a temp copy of it when it changes, read the temp copy and the delete the temp copy. I need to get hold of the text in the file whenever the server changes it.

• Binding for MinWidth property does not work in Silverlight

  - by Akash Kava

  I have noticed something very unusual today, I need to bind "MinWidth" property of TextBlock to some value, however following example does not work. It only accepts MinWidth at a time of creation, but after that it is not affected at all if LeftWidth property is changed at runtime, however if I bind LeftWidth property to WidthProperty it works well. Binding b = new Binding("LeftWidth"); // following never changes layout of control tb.SetBinding(TextBlock.MinWidthProperty,b); However, this one works correctly, // following never changes layout of control tb.SetBinding(TextBlock.WidthProperty,b); Now I also did hook events and tried to do InvalidateMeasure and InvalidateArrange on TextBlock, but it has no effect. Seems like Changing MinWidth Property after layout pass does not work at all. Can it be a bug in Silverlight? or Does anyone have any idea at all why MinWidth does not redo the layout?

• EE vs Computer Science: Effect on Developers' Approaches, Styles?

  - by DarenW

  Are there any systematic differences between software developers (sw engineers, architect, whatever job title) with an electronics or other engineering background, compared to those who entered the profession through computer science? By electronics background, I mean an EE degree, or a self-taught electronics tinkerer, other types of engineers and experimental physicists. I'm wondering if coming into the software-making professions from a strong knowledge of flip flops, tristate buffers, clock edge rise times and so forth, usually leads to a distinct approach to problems, mindsets, or superior skills at certain specialties and lack of skills at others, when compared to the computer science types who are full of concepts like abstract data types, object orientation, database normalization, who speak of "closures" in programming languages - things that make little sense to the soldering iron crowd until they learn enough programming. The real world, I'm sure, offers a wild range of individual exceptions, but for the most part, can you say there are overall differences? Would these have hiring implications e.g. (to make up something) "never hire an electron wrangler to do database design"? Could knowing about any differences help job seekers find something appropriate more effectively? Or provide enlightenment or some practical advice for those who find themselves misfits in a particular job role? (Btw, I've never taken any computer science classes; my impression of exactly what they cover is fuzzy. I'm an electronics/physics/art type, myself.)

• How do I create a patch compared to another changeset in Eclipse?

  - by Larsen

  I started working on an open source project that is using CVS where I want to submit patches. After having edited some files, I created a patch from the files that Eclipse showed as changed. Now I need to change a file for the second patch (that file is already in the first changeset), but the changes from the first changeset shouldn´t be in the second changeset. Therefore, I would need to somehow tell Eclipse that it should compare the changes to the result of the first changeset instead of to the CVS head revision. How can I do that?

• Neural network input preprocessing

  - by TND

  It's clear that the effectiveness of a neural network depends strongly on the format you give it to work with. You want to preprocess it into the most convenient form you can algorithmically get to, so that the neural network doesn't have to account for that itself. I'm working on a little project that (surprise!) is going to be using neural networks. My future goal is to eventually use NEAT, which I'm really excited about. Anyway, one of my ideas involves moving entities in continuous 2D space, from a top-down perspective (this would be a really cool game AI). Of course, unless these guys are blind, they're going to be able to see the world around them. There's a lot of different ways this information could be fed into the network. One interesting but expensive way is to simply render a top-down "view" of things, with the entities as dots on the picture, and feed that in. I was hoping for something much simpler to use (at least at first), such as a list of the x (maybe 7 or so) nearest entities and their position in relative polar coordinates, orientation, health, etc., but I'm trying to think of the best way to do it. My first instinct was to order them by distance, which would inherently also train the neural network to consider those more "important". However, I was thinking- what if there's two entities that are nearly the same distance away? They could easily alternate indexes in that list, confusing the network. My question is, is there a better way of representing this? Essentially, the issue is the network needs a good way of keeping track of who's who, while knowing (by being inputted) relevant information about the list of entities it can see. Thanks!

• BULK INSERT from one table to another all on the server

  - by steve_d

  I have to copy a bunch of data from one database table into another. I can't use SELECT ... INTO because one of the columns is an identity column. Also, I have some changes to make to the schema. I was able to use the export data wizard to create an SSIS package, which I then edited in Visual Studio 2005 to make the changes desired and whatnot. It's certainly faster than an INSERT INTO, but it seems silly to me to download the data to a different computer just to upload it back again. (Assuming that I am correct that that's what the SSIS package is doing). Is there an equivalent to BULK INSERT that runs directly on the server, allows keeping identity values, and pulls data from a table? (as far as I can tell, BULK INSERT can only pull data from a file) Edit: I do know about IDENTITY_INSERT, but because there is a fair amount of data involved, INSERT INTO ... SELECT is kinda of slow. SSIS/BULK INSERT dumps the data into the table without regards to indexes and logging and whatnot, so it's faster. (Of course creating the clustered index on the table once it's populated is not fast, but it's still faster than the INSERT INTO...SELECT that I tried in my first attempt) Edit 2: The schema changes include (but are not limited to) the following: 1. Splitting one table into two new tables. In the future each will have its own IDENTITY column, but for the migration I think it will be simplest to use the identity from the original table as the identity for the both new tables. Once the migration is over one of the tables will have a one-to-many relationship to the other. 2. Moving columns from one table to another. 3. Deleting some cross reference tables that only cross referenced 1-to-1. Instead the reference will be a foreign key in one of the two tables. 4. Some new columns will be created with default values. 5. Some tables aren’t changing at all, but I have to copy them over due to the "put it all in a new DB" request.

• What happens if a file I want to commit to SVN is updated so often I don't manage to do a merge quic

  - by sharptooth

  Consider a situation. I want to commit a changed file to SVN and see that someone else committed the same file after I checked it out, so I have to "update" and merge changes. While I'm doing that someone commits the same file again, so when I try to commit the merged file I have to update again. Now if other users commit often enough it looks like I will never be able to commit my changes. Is that really so? How is this problem solved in real development environments?

• how do I notify child controls of a change in the parent

  - by fishhead

  what is the best way to keep a child control up to date for changes in the parent. I have a number of child controls hosted inside my parent object and I can think of two ways to send change information to them. 1) wire the child control to an event in the parent. and fire that event on a change in the parent 2) keep a list of the children in an array and intenerate through the array when the change has happened and invoke a method in the child to handle the new changes. I hope I describe it okay. both work but there is probably a right way to handle this and a wrong way.

• Is it possible to tie a subscription to a iTunes account with in-app purhcase?

  - by erotsppa

  We're trying to implement a subscription service with in-app purchase in our app. The problem is our service does not require a user account for the past year of service. Users simply use this service with advertisements shown. We want to give them a subscription where they can buy for say, 3 months to have the advertisement removed. How can this be done? We'll have to make it a consumable because it is a subscription. But we wouldn't know when the subscription end. We can't save the state locally because the user might reinstall the app We can't save the state on the server and tie it to their device because sometimes the user changes device We don't have a user account to tie the subscription to and we don't want to introduce a user account system which spoils the experience. Is there some way of associating the purchase with their iTunes account? So that it is carried with them when they reinstall or changes device?

• Facebook Api - Local development, Testserver, Liveserver ... How?

  - by Thijs Kaspers

  I'm working on a new website that uses the Facebook API for users to login and several implementations of the graph Api. My workflow usually is: Development on localhost Development using MAMP/XAMPP or similar software Push to server - testing domain A team of people can test the changes for a few days to see if everything works as planned. Push to server - live domain Changes are live for public Facebook uses the site URL in the appsettings and for security reasons, they will only redirect to that url... Problem is.. I have localhost and 2 different domains. How can I make this work? Ofcourse I could edit the hostsfile, but that only fixes it for localhost.. Still no solution for the testdomain. Please tell me this is somehow possible! I'm getting more and more depressed with the Facebook API.

• How to thoroughly clean up a ruby on rails project?

  - by hip10

  Hi, I am very new to ruby on rails. I've installed a complicated ruby on rails project via github clone and bundle install, and I was making minor changes to it until it reaches a point whereby it is not stable anymore, sass was throwing strange exceptions, so did other ruby gems. For a rails project, is there a way to clean up the project (aka, remove any "compiled or cached code") and just run again. My alternative now is to go thru github clone and bundle install again, but that means all of my modified changes have to be reapplied again. What is rails equivalent of "make clean" in Java? Is "rake clean" the answer? Do we need to run any bundle commands?

• Can I automatically overwrite repository files using svn_load_dirs.pl or similiar?

  - by Andy Strang

  I am working with a legacy VSS repository which was transferred over to a new SVN repository a few months ago. In the meantime, before we go live with the SVN repository, we need to bring over all the changes that have happened on the VSS one between then and now. I was looking at different ways to do this which seem to be things such as: 1.) svn_load_dirs.pl then merge the files manually? 2.) svn import straight into the trunk and merge files manually 3.) checkout a working copy of my SVN repository, copy in the changed files which will overwrite some of the ones in my working copy then commit the changes. My question is, can any of these options be used (or any other options) to automate things so that I don't have to merge the files, and can instead just overwrite them? I think only Option 3 would do this but any help is appreciated.

• Documenting a Access Application for Developers

  - by Nitrodist

  I need to document a MS-Access application that was created, developed and maintained completely by a power-user over 10 years. This is an interesting situation because what they want is a manual so that a future developer can come in without prior domain knowledge and make changes to the frontend or the backend in a timely manner. There are a few questions on my mind for this little project: What is a good manual design creating application? Microsoft Word doesn't quite cut it. What kind of things would you, the developer, need to know in order to make changes to things like forms, reports, tables or other Access objects? Anything else I missed? Any pitfalls?

• Rolling back or re-creating the master branch in git?

  - by Matthew Savage

  I have a git repo which has a few branches - there's the master branch, which is our stable working version, and then there is a development/staging branch which we're doing new work in. Unfortunately it would appear that without thinking I was a bit overzealous with rebasing and have pulled all of the staging code into Master over a period of time (about 80 commits... yes, I know, stupid, clumsy, poor code-man-ship etc....). Due to this it makes it very hard for me to do minor fixes on the current version of our app (a rails application) and push out the changes without also pushing out the 'staged' new features which we don't yet want to release. I am wondering if it is possible to do the following: Determine the last 'trunk' commit Take all commits from that point onward and move them into a separate branch, more or less rolling back the changes Start using the branches like they were made for. Unfortunately, though, I'm still continually learning about git, so I'm a bit confused about what to really do here. Thanks!

• jquery vote up down, request for some help

  - by Billa

  I want to make some changes in the following piece of code. The demo of the code can be seen here. http://cyberbuff.noadsfree.com/lab/reddit_votes/ The above example shows calculated number of votes (vote ups - votes down). And when you click on any thumbe, it disappears the thumbs and shows the updated votes. I want to make changes that in begining it shows vote up and vote down separately (which are stored in database separately). and after thumb up or down is pressed, it should not remove the thumbs, but it should show the updated vote up and down separatetly. As shown in the image below. Here are pieces of code: Main page having html/CSS and jquery code. http://pastebin.com/RC6dj6N5 vote processng code: http://pastebin.com/heszKyDc PS.

• Why it is necessary to put comments on check-ins? [closed]

  - by Mik Kardash

  In fact, I always have something to put in when I perform a check-in of my code. However, the question I have is - Is it really so necessary? Does it help so much? How? From one point of view, comments can help you to keep track of changes performed with every check-in. Thus, I will be able to analyze the changes and identify a hypothetic problem a little bit quicker. On the other hand, it takes some time to write useful information into check-in. Is it worth it? What are the pros and cons of writing comments to every check-in? Is there any way to write "efficient" check-in comments?

• HTML, PHP No data in drop down box

  - by Makinitez21

  Hey, I am trying to figure out why a website's drop down box will not show any options. The data file for this drop down box comes from a microsoft access .mde file. The file is present and after the last update was working fine. Some changes happened to the site, i.e. text got added along with some photos. Im not saying this was when the drop down box went bad, but when it was discovered these were the only changes made. The data file seems fine as it is worked with everyday. Can anyone point me in the right direction as to where to begin looking for the bug? For a better idea of what I am talking about, check out the Site http://yogaalliance.org/teacher_search.cfm and try selecting a country. Thank you in advance

• TFS Automated Builds to Code Packages

  - by Adam Jenkin

  I would like to hear the best practices or know how people perform the following task in TFS 2008. I am intending on using TFS for building and storing web applications projects. Sometimes these projects can contain 100's of files (*.cs, *.acsx etc) During the lifetime of the website, a small bug will get raised resulting in say a stylesheet change, and a change to default.aspx.cs for example. On checking in these changes to TFS, and automated build would be triggered (great!), however for deploying the changes to the target production machine, I only need to deploy for example: style.css default.asx MyWebApplications.dll So my question is, can MSBuild be customized to generate a "code pack" of only the files which require deploying to the production server based on the changeset which cause the re-build?

• Override Django inlineformset_factory has_changed() to always return True

  - by John

  Hi, I am using the django inlineformset_factory function. a = get_object_or_404(ModelA, pk=id) FormSet = inlineformset_factory(ModelA, ModelB) if request.method == 'POST': metaform = FormSet (instance=a, data=request.POST) if metaform.is_valid(): f = metaform.save(commit=False) for instance in f: instance.updated_by = request.user instance.save() else: metaform = FormSet(instance=a) return render_to_response('nodes/form.html', {'form':metaform}) What is happening is that if I change any of the data then everything works ok and all the data gets updated. However if I don't change any of the data then the data is not updated. i.e. only entries which are changed go through the for loop to be saved. I guess this makes sense as there is no point saving data if it has not changed. However I need to go through and save every object in the form regardless of whether it has any changes on not. So my question is how do I override this so that it goes through and saves every record whether it has any changes or not? Hope this makes sense Thanks
