  • Offline Database Write Cache in C#

    - by Todd Gardner
    I have a windows service that receives a large amount of data that needs to be transformed and persisted to a database. To ensure that we do not lose data, I want to create a "Write cache" for the data that will continue regardless if the database is online. Once the database becomes available again, I would want it to flush the content of the cache back into the database. I've seen some articles indicating that I might be able to do this with NHibernate, but I haven't found it conclusively. What options exist for this, and is NHibernate the appropriate direction?

  • How to write this in better way?

    - by dario
    Hi all. Let's look at this code: IList<IHouseAnnouncement> list = new List<IHouseAnnouncement>(); var table = adapter.GetData(); //get data from repository object -> DataTable if (table.Rows.Count >= 1) { for (int i = 0; i < table.Rows.Count-1; i++) { var anno = new HouseAnnouncement(); anno.Area = float.Parse(table.Rows[i][table.powierzchniaColumn].ToString()); anno.City = table.Rows[i][table.miastoColumn].ToString(); list.Add(anno); } } return list; Is it better way to write this in less code and better fashion (must be :-) )? Maybe using labda (but let mi know how)? Thanks in advance!

  • Write a recursive function in C that converts a number into a string

    - by user3501779
    I'm studying software engineering, and came across this exercise: it asks to write a recursive function in C language that receives a positive integer and an empty string, and "translates" the number into a string. Meaning that after calling the function, the string we sent would contain the number but as a string of its digits. I wrote this function, but when I tried printing the string, it did print the number I sent, but in reverse. This is the function: void strnum(int n, char *str) { if(n) { strnum(n/10, str+1); *str = n%10 + '0'; } } For example, I sent the number 123 on function call, and the output was 321 instead of 123. I also tried exchanging the two lines within the if statement, and it still does the same. I can't figure out what I did wrong. Can someone help please? NOTE: Use of while and for loop statements is not allowed for the exercise.

  • How to write a list to a text file in the correct format

    - by lia1000
    I've got this piece of code that I want to write the output to a text file but with the correct format i.e. no brackets, single quotes so it appears as a formatted list. This is the code: file = open("env5.txt", "w"); for key in os.environ.keys(): env = os.environ[key]; key1 = key; list = str([key, env]).replace("'","").replace('[]', ''); list2 = list[1:-1]; print(list2); file.writelines(list2); file.close(); This is the original code: for key in os.environ.keys(): print(key, os.environ[key]); Many thanks

    Is there a better, more efficient way to write this code? It's a make shift drop down menu that allows user to RSVP for multiple people. Sorry, it's kind of a mess, but I think what I'm doing is clear. If not, I'm at my computer and will respond quickly with more info need be. //There's got to be a better way to do this $('#guest_num_1').click( function() { $('#num_guests a#quant_guests').html("1") $('.guest_name_2, .guest_name_3, .guest_name_4, .guest_name_5, .guest_name_6 ').hide() }); $('#guest_num_2').click( function() { $('#num_guests a#quant_guests').html("2") $('.guest_name_2').fadeIn() $('.guest_name_3, .guest_name_4, .guest_name_5, .guest_name_6').hide() }); $('#guest_num_3').click( function() { $('#num_guests a#quant_guests').html("3") $('.guest_name_2, .guest_name_3').fadeIn() $('.guest_name_4, .guest_name_5, .guest_name_6').hide() }); $('#guest_num_4').click( function() { $('#num_guests a#quant_guests').html("4") $('.guest_name_2, .guest_name_3, .guest_name_4').fadeIn() $('.guest_name_5, .guest_name_6').hide() }); $('#guest_num_5').click( function() { $('#num_guests a#quant_guests').html("5") $('.guest_name_2, .guest_name_3, .guest_name_4, .guest_name_5').fadeIn() $('.guest_name_6').hide() }); $('#guest_num_6').click( function() { $('#num_guests a#quant_guests').html("6") $('.guest_name_2, .guest_name_3, .guest_name_4, .guest_name_5, .guest_name_6').fadeIn() });

  • Java: howto write equals() shorter

    - by erikb
    I get headaches when I have to write nearly 10 lines of code to say 2 Objects are equal, when their type is equal and both's attribute is equal. You can easily see that in this way of writing the number of lines increase drastically with your number of attributes. public class Id implements Node { private String name; public Id(String name) { this.name = name; } public boolean equals(Object o) { if (o == null) return false; if (null == (Id) o) return false; Id i = (Id) o; if ((this.name != null && i.name == null) || (this.name == null && i.name != null)) return false; return (this.name == null && i.name == null) || this.name.equals(i.name); } }

  • How can I merge two SubVersion branches to one working copy without committing?

    - by Eric Belair
    My current SubVersion workflow is like so: The trunk is used to make small content changes and bug fixes to the main source code. Branches are used for adding/editing enhancements and projects. So, trunk changes are made, tested, committed and deployed pretty quickly. Whereas, enhancements and projects need additional user testing and approval. At time, I have two branches that need testing and approval at the same time. I don't want to merge to the trunk and commit until the changes are fully tested and approved. What I need to do is merge both branches to one working copy without any commits. I am using Tortoise SVN, and when I try to merge the second branch, I get an error message: Cannot merge into a working copy that has local modifications Is there a way that I can do this without committing either merge?

  • How to copy all recovery points to another drive? - Norton Ghost

    - by chobo2
    Hi I have Norton Ghost and I have 2 drives dedicated to backing up my files. One is an external drive the other is internal. Now my internal drive has filled up with backups and I now want to copy all those backups to my external drive. However it seems to want me to do it one by one. Can I do it like a batch or some mass copy so it does one after another so I can say have my computer all night on? My plan was to fill up my internal drive - copy it to my external drive - fill up my external drive - copy it to my external drive. Once my external drive would be filled up I then would start deleting the oldest backups but that probably would give me like 6 months of backs that I can back through if I would ever need too.

  • Why is implementing copy-paste in a touch screen based smartphone such a big deal?

    - by EpsilonVector
    I'm not entirely sure this is on-topic, but it definitely needs a programmer's understanding to be answered, and deals with general development (for a specific scenario) as opposed to a specific piece of code. In a way it also translates into "what are the challenges in doing X in a touch screen app", and similar questions have been asked here in the past. So here it is: When Apple didn't implement copy-pasting on the iPhone since version 1 I just assumed it was a UI issue- they were waiting until they figured out a good UI for it. But now the idea is out there, and Microsoft still released Windows Phone 7 without copy-pasting, promising it'll be ready in a few months. My question is: why does this takes a few months to implement? Are there some technological challenges that are unique to programming for a touch screen that I'm not familiar with?

  • How do I copy/clone a dynamic disk in Windows 7?

    - by PP
    I have some dynamic disks (or "partitions" but they are not really partitions) that I want to copy onto spare hard drives. I tried using gpartd (and fdisk for that matter) from a linux live disc. All it saw was hard drives with only one partition encasing the whole hard drive. So gpartd/fdisk is incapable of identifying the dynamic "partitions" and allowing me to copy them. Any tools that can be used to clone/copy a dynamic "partition"?

  • How do I copy an existing hard disc to a new one so I can boot off the new disc?

    - by Brian Hooper
    I currently have a failing hard drive which is the only hard drive in the machine. I have just bought a new hard drive to replace it, and my plan is to copy the contents of the old drive onto the new one, and then replace the old drive in the machine with the new one. I presumably can't just copy the whole directory structure (or can I)? What do I need to do to manage this, assuming it is possible? Is there a utility to do this for me? (The old drive is hopefully good for a few more hours.) (I hope by this means to keep all the software and configuration files as they are, to avoid having to re-install everything. Can that be done?)

  • What do I need to know to design a language and write a interpreter for it?

    - by alFReD NSH
    I know this question has been asked and even there are thousands of books and articles about it. But the problem is that there are too many, and I don't know are they good enough, I have to design a language and write a interpreter for it. The base language is javascript (using nodejs) but it's ok if the compiler was written in another language that I can use from node. I had done a research about compiler compilers in JS, there is jison (Bison implementaion in JS), waxeye, peg.js. I decided to give jison a try, due to the popularity and its being used by coffee script, so it should be able to cover my language too. The grammar definition syntax is similar to bison. But when I tried read the bison manual it seemed very hard to understand for me. And I think it's because I don't know a lot of things about what I'm doing. Like I don't what is formal language theory. I am experienced in Javascript (I'm more talented in JS than most average programmers). And also know basic C and C++ (not much experience but can write a working code for basic things). I haven't had any formal education, so I may not be familiar with some software engineering and computer science principles. Though everyday I try to grasp a lot of articles and improve. So I'm asking if you know any good book or article that can help me. Please also write why the resource you're suggesting is good. --update-- The language I'm trying to create, is not really complicated. All it has is expressions (with or without units), comparisons and logical operators. There are no functions, loops, ... The goal is to create a language that non-programmers can easily learn. And to write customized validations and calculations.

  • Why won't Ubuntu copy large files to FAT32 flash Drives?

    - by yurividal
    Since I installed 11.10 I am unable to copy large files (say 1gb or more) to ANY usb drive that is formated as FAT. The file starts copying, but soon an error appears, saying "Unable to Copy" . "Error splicing file: Input/output error". I am able to do it via terminal, using the cp command. I use Gnome3, but the same error has happened in Unity as well. Apparently it works if I format the USB drive as NTFS or EXT3, EXT4. But, for many appliances, FAT is necessary. The problem is also not with the USB port, because it works under Windows. It did not happen before, when I had 10.04 installed.

  • How can I copy a SQL Azure Database to a server on a different subscription?

    - by Tragedian
    I'm trying to create a copy of a SQL Azure database. The source and destination servers are associated with two different subscriptions, but they are located in the same data-centre. I've been reading Copying Databases in Windows SQL Azure Database and How to: Copy Your Databases (Windows Azure SQL Database) for instructions on this, but I'm not sure if my scenario is covered. I would like to use the CREATE DATABASE Database1B AS COPY OF Database1A; command, but I don't know what the implications are on the accounts used, or what I need to set up between the two databases before this command is possible. Has anybody achieved this type of copy and can elaborate?

  • Can I copy large files faster without using the file cache?

    - by Veazer
    After adding the preload package, my applications seem to speed up but if I copy a large file, the file cache grows by more than double the size of the file. By transferring a single 3-4 GB virtualbox image or video file to an external drive, this huge cache seems to remove all the preloaded applications from memory, leading to increased load times and general performance drops. Is there a way to copy large, multi-gigabyte files without caching them (i.e. bypassing the file cache)? Or a way to whitelist or blacklist specific folders from being cached?

  • Do you write unit tests for all the time in TDD?

    - by mcaaltuntas
    I have been designing and developing code with TDD style for a long time. What disturbs me about TDD is writing tests for code that does not contain any business logic or interesting behaviour. I know TDD is a design activity more than testing but sometimes I feel it's useless to write tests in these scenarios. For example I have a simple scenario like "When user clicks check button, it should check file's validity". For this scenario I usually start writing tests for presenter/controller class like the one below. @Test public void when_user_clicks_check_it_should_check_selected_file_validity(){ MediaService service =mock(MediaService); View view =mock(View); when(view.getSelectedFile).thenReturns("c:\\Dir\\file.avi"); MediaController controller =new MediaController(service,view); controller.check(); verify(service).check("c:\\Dir\\file.avi"); } As you can see there is no design decision or interesting code to verify behaviour. I am testing values from view passed to MediaService. I usually write but don't like these kind of tests. What do yo do about these situations ? Do you write tests for all the time ? UPDATE : I have changed the test name and code after complaints. Some users said that you should write tests for the trivial cases like this so in the future someone might add interesting behaviour. But what about “Code for today, design for tomorrow.” ? If someone, including myself, adds more interesting code in the future the test can be created for it then. Why should I do it now for the trivial cases ?
