• Turning A Stacked List into workable data

  - by BoSox

  In Excel I have a list of names that in the cell appear stacked, and I want each name in its own column. I was thinking Python may be a good way to do this? Example: Joe Smith John Hawk Mike Green Lauren Smith One cell will look exactly like that, with each name on its line within the cell but all of the names contained in the cell. I have 50 cells each with 1-20 stacked names and I want to put each name in its own cell on a given row. So, in my example all of those names would occupy the same row but each would have their own column. Any ideas?

• Process for linking static ObjC libraries in XCode

  - by madmik3

  I'm trying to link to a static library and I keep getting linker errors. I've found a few sites that post examples but I have not been able to see what I am doing wrong. First I create a project that will link to my lib add existing files find my .xcodeproj file select "Copy items into destination groups folder"... Select my host project as Add To Targets. Then I add a direct dependency to my host app expand targets double click MyHost.app click + under direct dependencies select my lib Then I set build flags double click MyHost application icon in Groups and Files. click the build tab then I set the OtherLinerFlag to -ObjC then I set Header Search Paths to my header file location for my static library. I pass the compile stage but any classes in my static lib cause linker error: literal-pointer@_OBJC@_cls_refs@SomeClass in MyHost.o thanks!

• Implement subitem in SQLite

  - by Mohit Deshpande

  How could I implement a sub item where the item would have a parent to that of the same item. For example, I have a database that holds tasks/todos. Each todo has a title(TEXT), completed(INTEGER [1 if true, 0 if false]), and due date(TEXT) column. I would like to add functionality to have subtasks, where a task could possibly have a parent task. How would I implement this in SQLite for Android? NOT IN SQL! So no foreign keys (triggers are allow, though)! Could I just have a separate table (subtask) and have a foreign key trigger to link subtask(INTEGER parent) to task(INTEGER PRIMARY KEY AUTOINCREMENT _id)? Or should I add a column to my original task table(INTEGER parent)? How could I implement this?

• jQuery Cookie Help

  - by Bruno

  Hi there.. So I have never attempted to use a cookie and was wondering if someone could possibly help me with some functionality I am trying to achieve.. Essentially I have a jQuery function that is fired when a user visits a webpage. What I would like to do is make it to where that animation only plays once.. Possibly leveraging some cookie that would tell it not to play again for x amount of days. I noticed that alot of people having questions about cookies and jQuery have been mentioned the following cookie plugin, but I dont even really know how to leverage it. Any ideas? Right now the animation is: $('#header, #footer, #secondary-column').fadeTo(600, 1); I would assume that if I could set a cookie to tell it the following: $('#header, #footer, #secondary-column').fadeTo(0, 1);

• How do I save a transient object that already exists in an NHibernate session?

  - by Daniel T.

  I have a Store that contains a list of Products: var store = new Store(); store.Products.Add(new Product{ Id = 1, Name = "Apples" }; store.Products.Add(new Product{ Id = 2, Name = "Oranges" }; Database.Save(store); Now, I want to edit one of the Products, but with a transient entity. This will be, for example, data from a web browser: // this is what I get from the web browser, this product should // edit the one that's already in the database that has the same Id var product = new Product{ Id = 2, Name = "Mandarin Oranges" }; store.Products.Add(product); Database.Save(store); However, trying to do it this way gives me an error: a different object with the same identifier value was already associated with the session How do I get around this problem?

• IIS7 301 Redirect from a List of URLs

  - by corymathews

  Recent changes are forcing me to add a bunch of 301 redirects. Seems that IIS7 is my best bet as compared to redirects within the files. I have found how to add them 1 by 1 but this requires the page/folder to exist (which most don't anymore(and creating them seems to defeat the point of the redirect)) and does not work on dynamic urls. I also cannot go to every page and add the redirects at the page level because some older pages are in php which is no longer supported on the new server. There is also no obvious pattern to the changes so each one must be made on its own. samples of the redirects page.htm - /page/ /folder/folder/ - /folder/folder.cfm /folder/folder/ - /folder/ /page.php?id=1 - page.htm

• Condensing multiple else if statements, referencing them from a table?

  - by Haskella

  Hi I'm about to type some 500 else if statements into my code (PHP) which have the exact same coding each: if (color=White); rgb = 255-255-255; print rgb; else if (color=Black); rgb = 0-0-0; print rgb; else if (color=Red); rgb = 255-0-0; print rgb; else if (color=Blue); rgb = 0-0-255; print rgb; [the list keeps going] I also (luckily) have a table that displays the color in the first column and rgb value in the next column for 500 of them... how do I use this to save time typing all those else if statements? Some how I have to reference the table file (made in excel, I'm guessing I'll have to save it as .csv?)

• Where do I put inline script in head with Zend Framework?

  - by Joel

  I'm reading the manual here: http://zendframework.com/manual/en/zend.view.helpers.html but I'm still confused. I have a script in my head that I'm converting to the layout/view for the Zend MVC: <script type="text/javascript"> var embedCode = '<object data="http://example.com" type="application/x-shockwave-flash" height="385" width="475"><param name="src" value="http://example.com" /><param name="allowfullscreen" value="true" /></object>' </script> I first tried to add it is an external file like this (in layout): $this->headScript()->appendFile('js/embeddedVideo.js')->appendScript($onloadScript); <head> <?php echo $this->headScript(); ?> </head> Didn't really work, but anyway, I'm wanting to just add the script and not add it as an external file. How do I do that? Thanks!

• Nested joins hide table names

  - by Sergio

  Hi: I have three tables: Suppliers, Parts and Types. I need to join all of them while discriminating columns with the same name (say, "id") in the three tables. I would like to successfully run this query: CREATE VIEW Everything AS SELECT Suppliers.name as supplier, Parts.id, Parts.description, Types.typedesc as type FROM Suppliers JOIN (Parts JOIN Types ON Parts.type_id = Types.id) ON Suppliers.id = Parts.supplier_id; My DBMS (sqlite) complains that "there is not such a column (Parts.id)". I guess it forgets table names once the JOIN is done but then how can I refer to the column id that belongs to the table Parts?

• Is there an easier way to typecast with unknown types?

  - by Adam S

  Hi all. I am writing a function to recurse my XAML and add all the controls to a hashtable, with their names being the keys. Unfortunately it seems like I have to go through and list every possible type: void Recurse_Controls(object start) { string start_type = start.GetType().ToString(); if (start_type == "StackPanel") { ControlsByName.Add(((StackPanel)start).Name, start); foreach (object item in ((StackPanel)start).Children) { Recurse_Controls(item); } } if (start_type == "Grid") { ControlsByName.Add(((Grid)start).Name, start); foreach (object item in ((Grid)start).Children) { Recurse_Controls(item); } } } Is there a simpler way of doing this?

• Question about mysql indexes on low to medium cardinality columns

  - by Kevin J

  I have a general question about the way that database indexing works, particularly in mysql. Let's say I have a table with a million rows with a column "ClientID" that is distributed relatively equally among 30 values. Thus, this column is very low cardinality (30) relative to the primary key (1 million). Now, I understand that you shouldn't create indexes on low cardinality fields. However, in this case, queries are only ever done with one of the 30 clientIDs. Thus, wouldn't creating an index on ClientID be helpful, as the search space is automatically reduced to 1/30th what it normally would be? Or is my understanding of how the index works flawed? Thanks

• How to virtually delete data from multiple tables that are linked by a foreign key ?

  - by Shantanu Gupta

  I am using Sql Server 2005 This is a part of my database diagram. I want to perform deletion on my database which will start from tblDomain up tp tblSubTopics. Consider that each table has IsDeleted column which has to be marked true if request was made to delete data. But that data shoud remain their physically. Tables which will have IsDeleted Column are tblDomain tblSubject tblTopic tblSubTopic Now I want, if a user marks one domain as deleted then all the refrence field should also get marked as deleted. i.e. 1 domain is related to 5 subjects, those 5 subjects are related to 25 topics, those 25 topics are related to 500 subtopics and so on. Then how should i mark all these fileds as Deleted. ?

• C# GridView dynamically built columns with textboxes ontextchanged

  - by tnriverfish

  My page is a bulk order form that has many products and various size options. I've got a gridview that has a 3 static columns with labels. There are then some dynamically built columns. Each of the dynamically built columns have a textbox in them. The textbox is for quantity. Trying to either update the server with the quantity entered each time a textbox is changed (possibly ontextchanged event) or loop though each of the rows column by column and gather all the items that have a quantity and process those items and their quantities all at once (via button onclick). If I put the process that builds the GridView behind a if(!Page.IsPostBack) then the when a textchanged event fires the gridview only gets the static fields and the dynamic ones are gone. If I remove the if(!Page.IsPostBack) the process to gather and build the page is too heavy on processing and takes too long to render the page again. Some advice would be appreciated. Thanks

• R: How can I use apply on rows of a data.frame and get out $column_name?

  - by John

  I'm trying to access $a using the following example: df<-data.frame(a=c("x","x","y","y"),b=c(1,2,3,4)) > df a b 1 x 1 2 x 2 3 y 3 4 y 4 test_fun <- function (data.frame_in) { print (data.frame_in[1]) } I can now access $a if I use an index for the first column: apply(df, 1, test_fun) a "x" a "x" a "y" a "y" [1] "x" "x" "y" "y" But I cannot access column $a with the $ notation: error: "$ operator is invalid for atomic vectors" test_fun_2 <- function (data.frame_in) { print (data.frame_in$a) } >apply(df, 1, test_fun_2) Error in data.frame_in$a : $ operator is invalid for atomic vectors Is this not possible?

• Debug Linux kernel pre-decompression stage

  - by Shawn J. Goff

  I am trying to use GDB to debug a Linux kernel zImage before it is decompressed. The kernel is running on an ARM target and I have a JTAG debugger connected to it with a GDB server stub. The target has to load a boot loader. The boot loader reads the kernel image from flash and puts it in RAM at 0x20008000, then branches to that location. I have started GDB and connected to the remote target, then I use GDB's add-symbol-file command like so: add-symbol-file arch/arm/boot/compressed/vmlinux 0x20008000 -readnow When I set a breakpoint for that address, it does trap at the correct place - right when it branches to the kernel. However, GDB shows the wrong line from the source of arch/arm/boot/compressed/head.S. It's 4 lines behind. How can I fix this? I also have tried adding the -s section addr option to add-symbol-file with -s .start 0x20008000; this results in exactly the same problem.

• Shortcut for adding to List in a HashMap

  - by Damo

  I often have a need to take a list of objects and group them into a Map based on a value contained in the object. Eg. take a list of Users and group by Country. My code for this usually looks like: Map<String, List<User>> usersByCountry = new HashMap<String, List<User>>(); for(User user : listOfUsers) { if(usersByCountry.containsKey(user.getCountry())) { //Add to existing list usersByCountry.get(user.getCountry()).add(user); } else { //Create new list List<User> users = new ArrayList<User>(1); users.add(user); usersByCountry.put(user.getCountry(), users); } } However I can't help thinking that this is awkward and some guru has a better approach. The closest I can see so far is the MultiMap from Google Collections. Are there any standard approaches? Thanks!

• How do you post content to a specific template position?

  - by ?????

  I can't figure this out. I purchased a template / theme from RocketTheme, but I can't figure out how to add content at a specific position. The templates have "module positions" that collapse. I'd like to add some content at one of the module positions. If I add articles, they seem to go into "mainbody". But I'd like to have content in other areas of the template. How do I take some text, images, or other content, and get them to display in these other positions (i.e., TOP-A, or FEATURE-A, etc)?

• Rails advanced queries with join and sum calculation

  - by Dustin Brewer

  I have two models: companies and expenses. Companies have many expenses and expenses belong to companies. My expense model has an 'amount' column. I was wondering if there is a way to perform a find based on a date range and the amount column of the expenses. Something like top 3 companies by total expense amounts over a 7 day period. I've tried for the better part of the day to get this to work, I've attempted joins, chaining named scopes, raw sql, etc. and I'm not having any luck. Thanks for the help.

• forcing Management Studio to use alter table instead of drop/recreate

  - by marco

  Hi! I'm wondering if is there a way to force MSSQL Management Studio to produce a script like this: ALTER TABLE Mytable ADD MyCol bit NOT NULL CONSTRAINT MyColDefault DEFAULT 0 WITH VALUES ALTER TABLE [dbo].Mytable ALTER COLUMN MyCol2 int NULL GO when I alter a very simple property of a column on a table. If I do this in the designer and ask for the produced script, the script doesn't do such simple tasks, but instead copies all the data in a tmp table, drops the original table, renames the tmp table with the original table name. And, of course, drops and recreates every constraint and relationships. Is there any option I can change to change this behaviour? Or, this may be possible, is there some danger I don't see in using the simple ALTER TABLE above? thanks.
