• castle dynamic proxy creation

  - by ashish.s

  I am implementing a design where my layer would sit between client and server, and whatever objects i get from server, i would wrap it in a transparent proxy and give to the client, that way i can keep a track of what changed in the object, so when saving it back, i would only send changed information. I looked at castle dynamic proxy, linfu, although they can generate a proxy type, but they cant take existing objects and wrap them instead. Wondering if its possible to do with these frameworks, or if there any other frameworks that enable this...

• Why do my horizontal toolstrips keep stacking verticaly?

  - by Eric

  I'm using a ToolStripContainer that contains three ToolStrips. At design time I move the ToolStrips to the positions I want them in, which is in a horizontal row across the top of the form like this: I then close and save the Form. However, if I open the form up again the ToolStrips end up stacked up on the left side of the ToolStripContainer like this: How can I keep the ToolStrips in the positions that I specify?

• Ubuntu 12.04 partioning an external drive without lossing data

  - by Menelaos Perdikeas

  I have an Ubuntu 12.04 with an external 1.5T disk (just for data). It is /dev/sdc1 seen below: $ df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/sda1 ext4 1451144932 27722584 1350794536 3% / udev devtmpfs 6199460 4 6199456 1% /dev tmpfs tmpfs 2482692 988 2481704 1% /run none tmpfs 5120 0 5120 0% /run/lock none tmpfs 6206724 284 6206440 1% /run/shm /dev/sdc1 fuseblk 1465135100 172507664 1292627436 12% /media/Elements The thing is I would like to implement this rsync-based backup strategy and I want to use my /dev/sdc1 external drive for that. Since the guide mentioned above recommends placing the backup directory in a separate partition I want to repartition the /dev/sdc1 external hard disk but retain existing data in a separate partition. E.g. split /dev/sdc1 into two partitions: (i) one to be used exclusively for the rsync-based backup and (ii) the other for the existing miscellaneous data. How should I go about partitioning with minimal risk to my existing data and what kind of filesystem do you recommend? I would prefer a console-based guide but unfortunately all the material I found on the web is oriented towards partitioning the main (bootable) disk and not an external fuseblk filesystem used only for passive data.

• How can I manipulate a VB6 Collection in .NET?

  - by jhominal

  Hello all, I am currently in the process of designing an interface for .NET software that would be consumed by COM objects - specifically, VB6. While I have found a number of pages by Microsoft detailing how to make an COM-interoperable interface, I am currently tripping over the use of Collections in design time: I would like to be able to use a standard VB6 "Collection object" in the .NET program - for example, specify an argument as being a VB6 collection - and thus minimize the time necessary for clients to consume the interface. Thank you in advance.

• Arranging VS2008 generated LinqToSql/EntityFramework data models/contexts in assemblies.

  - by JMSA

  What pattern should I use for data-access in case of VS2008 generated L2s or EF DataModels? Repository-pattern or what? As we know VS2008 generates Data-Models and DataContexts/ObjectContexts in the same file, then, how should I arrange my VS2008 assemblies in my VS2008 solution to achieve a layered design? If I use repository pattern, how should I arrange my assemblies in the VS2008 solution (as Data-Models and Data/Object-Contexts are stored in the same file...)? Any web/example link would be appreciated.

• Designing a solid API, how?

  - by emi1faber

  Obviously, APIs have exploded over the past few years, but many of them seem poorly designed when it comes to utilizing them... I have an opportunity to design an API however I see fit, but I would like it to be easy to use for those accessing it. Of course, keeping it as simple as possible is a big help, but what are the gotchas that people have run into out there? Anything that should be avoided at all costs or implemented at all costs?

• Customized command line parsing in Python

  - by Moshe

  I'm writing a shell for a project of mine, which by design parses commands that looks like this: COMMAND_NAME ARG1="Long Value" ARG2=123 [email protected] My problem is that Python's command line parsing libraries (getopt and optparse) forces me to use '-' or '--' in front of the arguments. This behavior doesn't match my requirements. Any ideas how can this be solved? Any existing library for this?

• On what platform did these popular programming languages originate?

  - by speciousfool

  Perhaps you know the story of HTTP and HTML being developed on a NeXT computer. I am curious which platform served as the first home for these programming languages: Ada C C++ C# D Erlang Fortran Haskell Java Javascript Lisp Logo MATLAB ML Perl PHP Prolog Python R Ruby Scheme SQL Smalltalk I thought it might be interesting to reflect on how the machine and operating environment lead to different design decisions. Or to see if some architecture or operating system variant was particularly fruitful for programming language development. A question for the historians among us.

• HTML+CSS+Javascript: hi, I'm getting crazy with this

  - by Patrick

  hi, I'm getting crazy with some browsers fixes to do everytime I'm doing a new website. For example, lately I've built my own Flash Video Player and I lost hours to fix some problems such as aligning it in IE and Firefox and Safari. Would be so cool to have a intermediary layer, I could use to design my website, without taking care of all browsers fixes... I guess I'm a dreamer

  Hi all, of all three choices (AIR+AJAX, +Flash, and +FLEX) I went on the AJAX route. But it seems that it can't show Flash embedded in HTML (using the traditional OBJECT tag). Is it by design? or my fault?

• boolean expressions, why just two terms?

  - by Ed Guiness

  Given that it's valid to write a = b = c = 2; It would also be nice, rather than bool allTwo = a == 2 && b == 2 && c == 2; to instead write bool allTwo = a == b == c == 2; But I can't. Is there a language-design reason for this?

• running same query in different databases

  - by user316833

  I wrote a query that I want to run in several access databases. I have 1000+ access databases with the same tables (same names, same fields). So far, I have been manually copying this query from a txt file to the sql view in the access query design screen for each database and then run it. I did not need to change the query language - everything is the same for the 1000 databases. Is there a way to automate this?
