  I am trying to output a document that looks like this. http://pastebin.com/dpBAY8Sb my issue is that I cannot find how to format the output I have to have a floating poing and format the distance between columns. My current code looks something like this. if (defined $longitude){ printf FILE ("%-8s %.6f","",$longitude); }else{ $longitude = ""; printf FILE ("%-20s ",$longitude); } but the extra "" throws off the whole column and it looks like this. pastebin.com/kcwHyNwb

• How to connect 2 mysql tables with 2 connection string

  - by denonth

  Hi all I need to connect 2 tables from 2 mysql databases that have 2 different connection strings and each is on the different server. I have this query: cmd = new MySqlCommand(String.Format("INSERT INTO {0} (a,b,c,d) SELECT (a,b,c,d) FROM {1}", ConfigSettings.ReadSetting("main_table"), ConfigSettings.ReadSetting("main_table")), con); So both table have the same columns. Thats why I have only one ConfigSettings.ReadSetting("main_table") for both of them as they are same. I have 2 connection strings and each is pointing to their server: con.ConnectionString = ConfigurationManager.ConnectionStrings["con1"].ConnectionString; con2.ConnectionString = ConfigurationManager.ConnectionStrings["con2"].ConnectionString; How to make this cmd to be workking with 2 different connection strings and with the same name for the table. Table name will change that's why it is saved in config.

• unexpected result from gnu sort

  - by funkycat

  when I try to sort the following text file 'input': test1 3 test3 2 test 4 with the command sort input the output is exactly the input. Here is the output of od -bc input : 0000000 164 145 163 164 061 011 063 012 164 145 163 164 063 011 062 012 t e s t 1 \t 3 \n t e s t 3 \t 2 \n 0000020 164 145 163 164 011 064 012 t e s t \t 4 \n 0000027 It's just a tab separated file with two columns. When I do sort -k 2 The output changes to test3 2 test1 3 test 4 which is what I would expect. But if I do sort -k 1 nothing changes with respect to the input, whereas I would expect 'test' to sort before 'test1'. Finally, if I do cat input | cut -f 1 | sort I get test test1 test3 as expected. Is there a logical explanation for this? What exactly is sort supposed to do by default, something like: sort -k 1 ? My version of sort: sort (GNU coreutils) 7.4

• Tweak Data in Doctrine Migration (say, by running some arbitrary queries)

  - by timdev

  I've got a migration that creates a couple of columns that act as foreign keys. In particular, I'm adding a creator_id and owner_id column to a model. These foreign keys indicate who created, and who currently owns, a particular kind of domain object. Users are managed by sfDoctrineGuardPlugin. What I'd like to do, for the purpose of the migration, is look up the (active) user with the lowest id, and default creator_id/owner_id to that. I don't see any particularly obvious/proper way to run arbitrary operations on the database during a migration. Does anyone know how?

• Managing important runtime business logic with regard to a codebase

  - by Daniel Beardsley

  I'm working on a project which will end up have a lot of application information stored in the form of records in a database. In this case, it's the configuration of data views: which grid columns to show/hide default filters to apply to each grid view column titles sorting subtotaling ... This information is a big part of the value of the application and is essential to it's function. The data will be altered by admins a fair amount, so it's not static and it wouldn't be appropriate to have to deploy a new version of the app every time the data changes. The question is, Where should this data be stored? It will definitely live in the database because that's how it's accessed, but I feel like it needs to also be kept with the version controlled codebase because it's an integral part of functioning of the application. Has anyone dealt with an issue like this before? What did you end up doing?

• Flex 4 how to layout spark controls in an html table type way

  - by Amy

  I have a group of controls and I want to organize them in a table like fashion. I want 1 row and 6 columns. Col 1,3,4,5,6 should all auto size to the contents and col 2 should take up the remaining available space. When the size of the group changes, only col2 width should change. I also want to be able to set the alignment of each cell. How can I do this in flex 4? I found a reference to mx:constraintColumns but this seems to be used with the canvas and in flex 4 adobe suggests not using canvases. Is there something similar in flex 4? I'm looking for something along the lines of Grid/Grid.ColumnDefinitions in silverlight.

• iPad javascript scrolling

  - by davids

  I'd like to get the same behaviour of the native javascript scrollTo function in iPad, just attaching a function to the swipe event and scrolling the content a specific number of pixels. That doesn't work in iPad using scrollTo or several different jquery plugins, like scrollTo or iScroll. I think I'm having problems because I'm working with an iframe, as I have another html document in it, with its body divided in columns, but I'm just showing the first one. The point of all this is that, after swiping, it should show the next/prev column, and I tried scrolling the iframe window or the inner's html body, which actually works in chrome, but it doesn't in iPad.

• JXTreeTable and BorderHighlighter Drawing Border on All Rows

  - by Kevin Rubin

  I'm using a BorderHighlighter on my JXTreeTable to put a border above each of the table cells on non-leaf rows to give a more clear visual separator for users. The problem is that when I expand the hierarchical column, all cells in the hierarchical column, for all rows, include the Border from the Highlighter. The other columns are displaying just fine. My BorderHighlighter is defined like this: Highlighter topHighlighter = new BorderHighlighter(new HighlightPredicate() { @Override public boolean isHighlighted(Component component, ComponentAdapter adapter) { TreePath path = treeTable.getPathForRow(adapter.row); TreeTableModel model = treeTable.getTreeTableModel(); Boolean isParent = !model.isLeaf(path.getLastPathComponent()); return isParent; } }, BorderFactory.createMatteBorder(2, 0, 0, 0, Color.RED)); I'm using SwingX 1.6.5.

• Extract multiple values from one column in MySql

  - by Neil

  I've noticed that MySql has an extensive search capacity, allowing both wildcards and regular expressions. However, I'm in somewhat in a bind since I'm trying to extract multiple values from a single string in my select query. For example, if I had the text "<span>Test</span> this <span>query</span>", perhaps using regular expressions I could find and extract values "Test" or "query", but in my case, I have potentially n such strings to extract. And since I can't define n columns in my select statement, that means I'm stuck. Is there anyway I could have a list of values (ideally separated by commas) of any text contained with span tags? In other words, if I ran this query, I would get "Test,query" as the value of spanlist: select <insert logic here> as spanlist from HtmlPages ...

• Database design: Calculating the Account Balance

  - by 001

  How do I design the database to calculate the account balance? 1) Currently I calculate the account balance from the transaction table In my transaction table I have "description" and "amount" etc.. I would then add up all "amount" values and that would work out the user's account balance. I showed this to my friend and he said that is not a good solution, when my database grows its going to slow down???? He said I should create separate table to store the calculated account balance. If did this, I will have to maintain two tables, and its risky, the account balance table could go out of sync. Any suggestion? EDIT: OPTION 2: should I add an extra column to my transaction tables "Balance". now I do not need to go through many rows of data to perform my calculation. Example John buys $100 credit, he debt $60, he then adds $200 credit. Amount $100, Balance $100. Amount -$60, Balance $40. Amount $200, Balance $240.

• Refreshing metadata on user functions t-SQL

  - by luckyluke

  I am doing some T-SQL programming and I have some Views defines on my database. The data model is still changing these days and I have some table functions defined. Sometimes i deliberately use select * from MYVIEW in such a table function to return all columns. If the view changes (or table) the function crashes and I need to recompile it. I know it is in general good thing so that it prevents from hell lotta errors but still... Is there a way to write such functions so the dont' blow up in my face everytime I change something on the underlying table? Or maybe I am doing something completely wrong... Thanks for help

• Displaying a collection of controls in a specific way in WPF

  - by Alvaro

  I have a collection of controls "MyCollection" wich changes in the Runtime. And I have to follow some constraints for that, for example: If my parameter "MyCollection.Count = 4" the property "NumberOfcolumns" will have the value 2, in order to create new Lines, and show the controls Two per Two. This is how I'm displaying my collection : <ItemsControl ItemsSource="{Binding MyCollection}" BorderThickness="0" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" > <ItemsControl.ItemsPanel> <ItemsPanelTemplate > <UniformGrid Columns="{Binding NumberOfColumns}" VerticalAlignment="Center" HorizontalAlignment="Center" Background="Transparent"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> The problem is that my controls have different sizes, and as In UniformGrids, Cells are uniform... My design is not really pretty, because I have little controls shown in big Cells !! Can someone help me to solve this problem ? NB: Please give me a detailled solution if possible, not something like : "Use WrapPanel..."

• To join or not to join - database structure

  - by Industrial

  Hi! We're drawing up the database structure with the help of mySQL Workbench for a new app and the number of joins required to make a listing of the data is increasing drastically as the many-to-many relationships increases. The questions: Is it really that bad to merge tables where needed and thereby reducing joins? Is there a better way then pivot tables to take care of many-to-many relationships? We discussed about instead storing all data in serialized text columns and having the application make the sorting instead of the database, but this seems like a very bad idea, even though that the database will be heavily cached. What do you think? Thanks!

• Cannot edit ColumnDefinitions property in Visual Studio WPF application, ellipsis are invisible!

  - by SLC

  I have a window that looks like this: <Window x:Class="MyWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="My Title" Height="300" Width="300" ResizeMode="NoResize" SizeToContent="Height" WindowStartupLocation="CenterOwner"> <DockPanel> <Grid x:Name="MyGrid" DockPanel.Dock="Top" Margin="10"> </Grid> </DockPanel> </Window> Pretty simple. The instructions I am following suggest that if I click the item, the properties window will appear (it does), and then I can click ColumnDefinitions (which is a Collection) to bring up the Collection Editor and add some columns. However, the ColumnDefinitions property looks like this: The ColumnDefinitions ellipsis you'd normally press is gone, or invisible, or something. Any idea why?

• Compare values in each column of two Oracle Types

  - by colinjameswebb

  I've been playing around with the pluto-test-framework today, and I'd like to get some existing functions into a test harness with it. I have lots of functions with this type of specification. FUNCTION DO_SOME_STUFF (pOldSchedule IN SCHEDULE_OBJ, pNewSchedule OUT SCHEDULE_OBJ, pLoggerContext IN OUT LOGGER_CONTEXT_OBJ) RETURN NUMBER; It takes pOldSchedule, does some stuff to it, and then returns pNewSchedule. The logger_context just does logging. As part of a test, I'd like to be able to compare the values in each of the columns of the type, without having to write individual IF statements. It'll need to return boolean to signify whether or not pOldSchedule and pNewSchedule match. Any ideas?

• Python Parse CSV Correctly

  - by cornerstone

  I am very new to Python. I want to parse a csv file such that it will recognize quoted values - For example 1997,Ford,E350,"Super, luxurious truck" should be split as ('1997', 'Ford', 'E350', 'Super, luxurious truck') and NOT ('1997', 'Ford', 'E350', '"Super', ' luxurious truck"') the above is what I get if I use something like str.split(). How do I do this? Also would it be best to store these values in an array or some other data structure? because after I get these values from the csv I want to be able to easily choose, lets say any two of the columns and store it as another array or some other data structure. Thanks in advance.
