  • Ninject caching an injected DataContext? Lifecycle Management?

    - by awrigley
    I had a series of very bizarre errors being thrown in my repositories. Row not found or changed, 1 of 2 updates failed... Nothing made sense. It was as if my DataContext instance was being cached... Nothing made sense and I was considering a career move. I then noticed that the DataContext instance was passed in using dependency injection, using Ninject (this is the first time I have used DI...). I ripped out the Dependency Injection, and all went back to normal. Instantly. So dependency injection was the issue, but I still don't know why. I am speculating that Ninject was caching the injected DataContext. Is this correct? Is there a way of configuring the lifecycle management of injected parameters? If so, what would be the best configuration to use to have the DataContext behave like a normal DataContext, ie, no caching across requests?

  • How can I replace the contents of a scrollable div without jumping to the top?

    - by RenderIn
    I have a div with the overflow: auto style. It is populated via AJAX with a result table. The rows in this div are editable, and with each edit I refresh the contents. The problem is, if the user edits something at the bottom of the div, the refresh brings them back to the top. I had some luck using anchors with Firefox, but not all versions of IE jumped to the anchors within the div. Is there any way to replace the contents of a div like this without having the scrollbar jump to the top? Any other suggestions? I like to refresh the entire set of results rather than just the updated row if possible, but if there are no workarounds I guess I will pursue that instead.

  • Generate encoding String according to creation order.

    - by Tony
    I need to generate encoding String for each item I inserted into the database. for example: x00001 for the first item x00002 for the sencond item x00003 for the third item The way I chose to do this is counting the rows. Before I insert the third item, I count against the database, I know there're already 2 rows, so the next encoding is ended with 3. But there is a problem. If I delete the second item, the forth item will not be the x00004,but x00003. I can add additional columns to table, to store the next encoding, I don't know if there's other better solutions ?

  • Database Design Question: GUID + Natural Numbers

    - by Alan
    For a database I'm building, I've decided to use natural numbers as the primary key. I'm aware of the advantages that GUID's allow, but looking at the data, the bulk of row's data were GUID keys. I want to generate XML records from the database data, and one problem with natural numbers is that I don't want to expose my database key's to the outside world, and allow users to guess "keys." I believe GUID's solve this problem. So, I think the solution is to generate a sparse, unique iD derived from the natural ID (hopefully it would be 2-way), or just add an extra column in the database and store a guid (or some other multibyte id) The derived value is nicer because there is no storage penalty, but it would be easier to reverse and guess compared to a GUID. I'm (buy) curious as to what others on SO have done, and what insights they have.

  • How to pass or display mySQL data based on subscription or billing

    - by spm
    I want to build a PHP based site where, the user can view data based on the types of data they've paid for. Allow me to use something simple for an example. Let's say historical data for basketball was not readily available but could be purchased. Simple information such as the Winner, Loser, Final score and date are all stored in a mySQL table. What would be involved so that, when the user logs in, they can only see the historical data they have paid for. My theories so far about the architecture: I imagined a mySQL table storing True or False values for all historical game data they have paid for. Based on this, a 'data chart' object enables the user to view all data within their mySQL row which has a value of 'true.' Follow ups: Assuming I am correct, what methods are popular or practical for this type of service.

  • tools for creating user-friendly command-line prompt?

    - by davka
    I notice that some programs (e.g. sqlite, mysql client) provide a command-line prompt that is very similar in capabilities to the bash's, including: line editing with left and right arrows, delete, insert, ^K, etc. history browsing with up and down arrows ^R for reverse i-search in command history which make me think that they are using the same toolset for this. I'd like to create a prompt with similar capabilities in my program, which tools can I use? I prefer it to have the same functionality as in bash, so that the users would be familiar with it.

  • Python CSV file processing

    - by kingwarchief
    I just got introduced to python, the first language I get to learn, and I have this question below: I have an excel based CSV file with two columns (or rows, Pythonically) that I am working on. What I need to do is to perform some operations so that I can compare the two data entries in each 'row'. To be more precise, one column has constant numbers all the way down, whereas the other column varies. So I need to count the number of times the varying column data entry values crosses the constant value on the other column. For example: Varying Column; Constant Column 24 25 26 25 crosses 27 25 26 25 25.5 25 23 25 crossed 26 25 crossed So in this case the number of times there is a cross

  • SQL Script To Generate a Database Dictionary **With Linked Fields**

    - by Albert
    I would like to generate a Data Dictionary for a SQL Server 2008 database that has one row for each field, and the following columns: table_name field_name data_type link_table (for when the field in question is a foreign key) link_field (for when the field in question is a foreign key) I can get the first 3 columns with something like the SQL script below...but I don't know how to get the last two columns of foreign key information. INFORMATION_SCHEMA.TABLE_CONSTRAINTS gets close, but doesn't have the data I'm looking for. Can someone help with this point? SELECT TABLE_NAME,COLUMN_NAME,DATA_TYPE FROM INFORMATION_SCHEMA.COLUMNS Secondarily if anyone has any suggestions on additional fields which would be helpful please post.

  • How to insert an n:m-relationship with technical primary keys generated by a sequence?

    - by bitschnau
    Let's say I have two tables with several fields and in every table there is a primary key which is a technical id generated by a database sequence: table1 table2 ------------- ------------- field11 <pk> field21 <pk> field12 field22 field11 and field21 are generated by sequences. Also there is a n:m-relationship between table1 und table2, designed in table3: table3 ------------- field11 <fk> field21 <fk> The ids in table1 und table2 are generated during the insert statement: INSERT INTO table1 VALUES (table1_seq1.NEXTVAL, ... INSERT INTO table2 VALUES (table2_seq1.NEXTVAL, ... Therefore I don't know the primary key of the added row in the data-access-layer of my program, because the generation of the pk happens completely in the database. What's the best practice to update table3 now? How can I gain access to the primary key of the rows I just inserted?

  • Select 2 Rows from Table when COUNT of another table

    - by Marcus
    Here is the code that I currently have: SELECT `A`.* FROM `A` LEFT JOIN `B` ON `A`.`A_id` = `B`.`value_1` WHERE `B`.`value_2` IS NULL AND `B`.`userid` IS NULL ORDER BY RAND() LIMIT 2 What it currently is supposed to do is select 2 rows from A when the 2 rows A_id being selected are not in value_1 or value_2 in B. And the rows in B are specific to individual users with userid. What I need to do is make it also so that also checks if there are already N rows in B matching a A_id (either in value_1, or value_2) and userid, and if there are more than N rows, it doesn't select the A row.

  • Sql Server XML-type column duplicate entry detection

    - by aaaa bbbb
    In Sql Server I am using an XML type column to store a message. I do not want to store duplicate messages. I only will have a few messages per user. I am currently querying the table for these messages, converting the XML to string in my C# code. I then compare the strings with what I am about to insert. Unfortunately, Sql Server pretty-prints the data in the XML typed fields. What you store into the database is not necessarily exactly the same string as what you get back out later. It is functionally equivalent, but may have white space removed, etc. Is there an efficient way to compare an XML string that I am considering inserting with those that are already in the database? As an aside, if I detect a duplicate I need to delete the older message then insert the replacement.

  • Vertically center CSS techniques don't work in Chrome

    - by at.
    I've gone through stackoverflow questions and a whole bunch of articles on vertically centering text like the following: http://blog.themeforest.net/tutorials/vertical-centering-with-css/ None of the techniques seem to work with the latest version of Chrome. Is that just the nature of Chrome? My text just always appears at the top. It seems that whenever I use 50% or 100% as values for CSS's height or top, nothing happens. I just need a single line of text vertically centered. line-height isn't helpful because I want it centered in the middle of the browser window... I don't know how tall the browser window is going to be. UPDATE: The problem is apparently Foundation 4. Once I delete the following everything works as expected: <link href="/assets/foundation_and_overrides.css?body=1" media="screen" rel="stylesheet" /> Any idea on how to make it work with Foundation 4?

  • What would be the best schema to store the 'address' for different entities?

    - by Cesar
    Suppose we're making a system where we have to store the addrees for buildings, persons, cars, etc. The address 'format' should be something like: State (From a State list) County (From a County List) Street (free text, like '5th Avenue') Number (free text, like 'Chrysler Building, Floor 10, Office No. 10') (Yes I don't live in U.S.A) What would be the best way to store that info: Should I have a Person_Address, Car_Address, ... Or the address info should be in columns on each entity, Could we have just one address table and try to link each row to a different entity? Or are there another 'better' way to handle this type of scenario? How would yo do it?

  • Why do a small amount of add/deletes take several seconds in EF4?

    - by TomWij
    Using the Entity Framework 4. I have created a Code First database in the past and a piece of code needs to delete and add 16 objects, this takes 6 seconds each. That's 300+ ms for each query! The deletes/adds occur in a foreach scope and there is a SaveChanges() outside the foreach. In the above image you see that each takes 6 seconds, which is 34% of the time, for 16 calls. That doesn't sound normal to me... Why is this and how can I improve the performance? If there is no solution: Are there any workarounds I can use? It would be a pain to rewrite my project...

  • NSCFType keeps occurring, something is not being released?

    - by user1493543
    I'm attempting to delete files from the documents directory using a tableview/array combination. For some reason, my NSString pointing to the Documents directory path is being converted to a NSCFType (which after some research, I understand is happening because a variable is not being released). Because of this, the application crashes at the line NSString *lastPath = [documentsDirectory stringByAppendingPathComponent:temp]; claiming that NSCFType cannot recognize the method stringByAppendingPathComponent. I would appreciate if someone could help me out (I hope I have explained this clearly enough). - (void) tableView: (UITableView *) tableView commitEditingStyle: (UITableViewCellEditingStyle) editingStyle forRowAtIndexPath: (NSIndexPath *) indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { NSString *temp = [directoryContent objectAtIndex:indexPath.row]; NSLog(temp); NSString *lastPath = [documentsDirectory stringByAppendingPathComponent:temp]; [[NSFileManager defaultManager] removeItemAtPath:lastPath error:nil]; - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); documentsDirectory = [paths objectAtIndex:0]; directoryContent = [[[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:nil] retain]; //tableview handling below }

  • varchar data type to datetime data type resulted in an out-of-range??

    - by leen3o
    Very weird problem occurred, I have moved a site from one server to another - All is working, but any query involving a date is playing up. I get the following: DELETE FROM MYTABLE WHERE categoryId = -2 AND datecreated < '3/23/2010'; The conversion of a varchar data type to a datetime data type resulted in an out-of-range value Now what's strange is I have changed the LCID to 1033 on the new server as the date is showing as US format and its still throwing an error! I then tried 2057 and again the same error? Made no difference. I'm a little confused, as this is a working site from a server with IIS6 - The locale is 1033 on that server and it works perfectly!! :S I have just tried thrown a Cdate() around the date too and yet again the same error??? Any ideas??

  • Checking if a boolean column is true in MySQL/Rails

    - by Pygmalion
    Rails and MySQL: I have a table with several boolean columns representing tags. I want to find all the rows for which a specific one of these columns is 'true' (or I guess in the case of MySQL, '1'). I have the following code in my view. @tag = params[:tag] @supplies = Supply.find(:all, :conditions=>["? IS NOT NULL and ? !=''", @tag, @tag], :order=>'name') The @tag is being passed in from the url. Why is it then that I am instead getting all of my @supplies (i.e. every row) rather than just those that are true for the column for @tag. Thanks!

  • Bug in Programming Interviews Exposed?

    - by Sam
    Hi, I could not find an errata for the 2nd edition of this book. My question concerns the if-statement in the following piece of code. void removeHead (Node ** head) { Node * temp; if (!(*head)) { temp = (*head)->next; delete *head; *head = temp; } } So I understand that the point of the if-statement is to check if the Node is null. However by adding an additional "!" to the evaluation, wouldn't this negate the false value of null? Would it be correct to change it to something like: if (*head) { ... } Also if anyone knows where I can find an official errata for the 2nd edition that would be great. Thanks, Sam

  • Disabling security warning caused by BaseIntermediateOutputPath?

    - by Chris R. Donnelly
    Hi all, Our team overrides BaseIntermediateOutputPath (and other related properties) in our Visual Studio projects in order to have build artifacts go outside the main tree. However, this causes an annoying warning dialog to appear when you open a project for the first time in a new location (which happens on new machines, when you check out a branch to a new location, have to delete corrupted .suo/.user files, etc.). Is there any way to disable the warning? FYI, we are using Visual Studio 2008, and we have encountered this warning on Windows XP as well as Windows 7, so it is not UAC-related.

  • Using True and False to select items to print

    - by user1753915
    I have a workbook that contains rows of information that needs to printed to a seperate worksheet in excel. I am trying to utilize a checkbox to indicate which items need to print and which items need to be skipped. The checkbox is located in column "A" and once checked and the macro ran, I want it to pick up the data in each cell of that particular row, transfer it a seperate worksheet (form), prompt and save the worksheet to pdf, clear the form, and then return to the main worksheet to continue until all rows have been checked. However, right now, my code is only looping through the very first "TRUE" statement and not continuing to the rest. Here is the code: Private Sub CommandButton1_Click() On Error GoTo ErrHandler: Dim i As Integer For i = 1 To 10 If ActiveSheet.OLEObjects("CheckBox" & i).Object.Value = False Then Else If ActiveSheet.OLEObjects("CheckBox" & i).Object.Value = True Then Call PrintWO Else End If Do Until ActiveSheet.OLEObjects("CheckBox" & i).Object.Value = 10 MsgBox "Nothing Selected to Print" Exit Do Exit Sub Loop End If Next i ErrHandler: End Sub
