  • How can I get awk input from a file and add my own text to the data?

    - by xs2dhillon
    Assume that I have a text file separated by colons. I understand how to display the entire text file or any specific column using awk. However, what I want to do is to get the awk output and then display it by adding my own text using a shell script? For example, assume that my text file is: England:London:GMT USA:Washington:EST France:Paris:GMT What I want to do is to display this input into the below format: COUNTRY: England CAPITOL: London TIMEZONE: GMT COUNTRY: USA CAPITOL: Washington TIMEZONE: EST COUNTRY: France CAPITOL: Paris TIMEZONE: GMT

  • Add columnname and data from datatable to a dictionary? C#

    - by Nick
    Hi, I am looping through a datatable and currently I do string customerId = row["CustomerId"].ToString(); string companyName = row["Company Name"].ToString(); Instead of declaring every variable how do I add these do a dictionary? I was thinking something like: foreach (DataRow row in customerTbl.Rows) { Dictionary<string, string> customerDictionary = new Dictionary<string, string>(); customerDictionary.Add(row[].ToString(), row[].ToString()); so yeah, how do I get the row name and value into there? Thanks in advance.

  • T-SQL - Is there a (free) way to compare data in two tables?

    - by RPM1984
    Okay so i have table a and table b. (SQL Server 2008) Both tables have the exact same schema. For the purposes of this question, consider table a = my local dev table, table b = the live table. I need to create a SQL script (containing UPDATE/DELETE/INSERT statements) that will update table b to be the same as table a. This script will then be deployed to the live database. Any free tools out there that can do this, or better yet a way i can do it myself? I'm thinking i probably need to do some type of a join on all the fields in the tables, then generate dynamic sql based on that. Anyone have any ideas?

  • How can I incorporate a data bound list of MenuItems to another MenuItem in WPF?

    - by Julien Poulin
    I have a 'File' MenuItem were I would like to display a list of recently opened files. Here is the xaml I have now: <MenuItem Header="File}"> <MenuItem Header="Preferences..." Command="{Binding ShowOptionsViewCommand}" /> <Separator /> <ItemsControl ItemsSource="{Binding RecentFiles}"> <ItemsControl.ItemTemplate> <DataTemplate> <MenuItem Header="{Binding DisplayPath}" CommandParameter="{Binding}" Command="{Binding Path=DataContext.OpenRecentFileCommand, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Window}}}"> </MenuItem> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> <Separator /> <MenuItem Header="Exit" Command="{Binding CloseCommand}" /> </MenuItem> However, when I use this code, there is a weird offset around the MenuItems and it looks like there is a container around them. How can I get rid of that? Here is a screenshot of what it looks like:

  • How do you extract data from a Date/Time widget from a C++ MFC dialog in VS2008

    - by jkerian
    This is a fairly basic question, but I haven't been able to find any from-to guides from VS6-VS2008. I have a dialog box that contains controls of various types, I've discovered the way of auto-generating OnBnClickedMyFooBarButtonHere() methods via the Properties dialog on the dialog editor. I can also use CWnd::GetDlgItemText(int ,CString &) to extract text, and the oddly paramaterized GetDlgItemInt(int, bool*, bool) to extract signed integers, but is there really no other option for a Date or Time value other than Manually adding in all the DDX_ crap that the class wizard used to do in VS6 Using GetDlgItemText and then parsing whatever it gives me?

  • how to avoid repeating code?

    - by helloWorld
    I have some technical question, I have repeating code in my work, and I want to get rid of it, so I know that in C++ it is not good idea to use macro, but instead I must use inline function, is it good idea to use this function as inline: list<Data>::iterator foo(int data){ if(dataExists(data)){ list<Data>::iterator i; for(i = Data.begin(); i != Data.end(); ++i){ if(i->getData() == data){ break; } return i; //here I have one more problem, what can I return if data doesn't exist? } I'm beginner, and I think that this function is very unsafe, can somebody please give me advice, how can I improve my code, thanks in advance P.S. what usually do You use to avoid repeating code?

  • Illegal Start of Expression

    - by Kraivyne
    Hello there, I have just started to learn the very basics of Java programming. Using a book entitled "Programming Video Games for the Evil Genius". I have had an Illegal Start of Expression error that I can't for the life of me get rid of. I have checked the sample code from the book and mine is identical. The error is coming from the for(int i = difficulty; i = 0; i- - ) line. Thanks for helping a newbie out. import javax.swing.*; public class S1P4 {public static void main(String[] args) throws Exception { int difficulty; difficulty = Integer.parseInt(JOptionPane.showInputDialog("How good are you?\n"+ "1 = Great\n"+"10 = Terrible")); boolean cont = false; do { cont = false; double num1 = (int)(Math.round(Math.random()*10)); double num2; do { num2 = (int)(Math.round(Math.random()*10)); } while(num2==0.0); int sign = (int)(Math.round(Math.random()*3)); double answer; System.out.println("\n\n*****"); if(sign==0) { System.out.println(num1+" times "+num2); answer = num1*num2; } else if(sign==1) { System.out.println(num1+" divided by"+num2); answer = num1/num2; } else if(sign==1) { System.out.println(num1+" plus "+num2); answer = num1+num2; } else if(sign==1) { System.out.println(num1+" minus "+num2); answer = num1-num2; } else { System.out.println(num1+" % "+num2); answer = num1%num2; } System.out.println("*****\n"); for(int i = difficulty; i >= 0; i- - ) { System.out.println(i+"..."); Thread.sleep(500); } System.out.println("ANSWER: "+answer); String again; again = JOptionPane.showInputDialog("Play again?"); if(again.equals("yes")) cont = true; } while(cont); } }

  • How to adjust the distribution of values in a random data stream?

    - by BCS
    Given a infinite stream of random 0's and 1's that is from a biased (e.g. 1's are more common than 0's by a know factor) but otherwise ideal random number generator, I want to convert it into a (shorter) infinite stream that is just as ideal but also unbiased. Looking up the definition of entropy finds this graph showing how many bits of output I should, in theory, be able to get from each bit of input. The question: Is there any practical way to actually implement a converter that is nearly ideally efficient?

  • Howto display or view encrypted data in encrypted form?

    - by Brian Gianforcaro
    In the Wikipedia Article on Block Cipher Modes they have a neat little diagram of an unencrypted image, the same image encrypted using ECB mode and another version of the same image encrypted using another method. At university I have developed my own implementation of DES (you can find it here) and we must demo our implementation in a presentation. I would like to display a similar example as shown above using our implementation. However most image files have header blocks associated with them, which when encrypting the file with our implementation, also get encrypted. So when you go to open them in an image viewer, they are assumed to be corrupted and can't be viewed. I was wondering if anybody new of a simple header-less image format which we could use to display these? Or if anyone had any idea's as to how the original creator of the images above achieved the above result? Any help would be appreciated, Thanks Note: I realise rolling your own cryptography library is stupid, and DES is considered broken, and ECB mode is very flawed for any useful cryptography, this was purely an academic exercise for school. So please, no lectures, I know the drill.

  • parallel.foreach with custom collection

    - by SchwartzE
    I am extending the System.Net.Mail.MailAddress class to include an ID field, so I created a new custom MailAddress class that inherited from the existing class and a new custom MailAddressCollection class. I then overrode the existing System.Net.Mail.MailMessage.To to use my new collection. I would like to process the recipients in parallel, but I can't get the syntax right. This is the syntax I am using. Parallel.ForEach(EmailMessage.To, (MailAddress address) => { emailService.InsertRecipient(emailId, address.DisplayName, address.Address, " "); }); I get the following errors: The best overloaded method match for 'System.Threading.Tasks.Parallel.ForEach(System.Collections.Generic.IEnumerable, System.Action)' has some invalid arguments Argument 1: cannot convert from 'EmailService.MailAddressCollection' to 'System.Collections.Generic.IEnumerable' What syntax do I need to use custom collections?

  • Array as struct database?

    - by user2985179
    I have a struct that reads data from the user: typedef struct { int seconds; } Time; typedef struct { Time time; double distance; } Training; Training input; scanf("%d %lf", input.time.seconds, input.distance); This scanf will be looped and the user can input different data every time, I want to store this data in an array for later use. I THINK I want something like arr[0].seconds and arr[0].distance. I tried to store the entered data in an array but it didn't really work at all... Training data[10]; data[10].seconds = input.time.seconds; data[10].distance = input.distance; The data will wipe when the program closes and that's how I like it to be. So I want it to be stored in an array, no files or databases!

  • Is fetching data from database a get-method thing?

    - by theva
    I have a small class that I call Viewer. This class is supposed to view the proper layout of each page or something like that... I have a method called getFirstPage, when called the user of this method will get a setting value for which page is currently set as the first page. I have some code here, I think it works but I am not really shure that I have done it the right way: class Viewer { private $db; private $user; private $firstPage; function __construct($db, $user) { $this->db = $db; if(isset($user)) { $this->user = $user; } else { $this->user = 'default'; } } function getFistPage() { $std = $db->prepare("SELECT firstPage FROM settings WHERE user = ':user'"); $std->execute(array(':user' => $user)); $result = $std->fetch(); $this->firstPage = $result['firstPage']; return $this->firstPage; } } My get method is fetching the setting from databse (so far so good?). The problem is that then I have to use this get method to set the private variable firstPage. It seems like I should have a set method to do this, but I cannot really have a set method that just fetch some setting from database, right? Because the user of this object should be able to assume that there already is a setting defined in the object... How should I do that?

  • Are methods also serialized along with the data members in C#?

    - by Shaza
    Hey all, The title is obvious, I need to know if methods are serialized along with object instances in C#, I know that they don't in Java but I'm a little new to C#. If they don't, do I have to put the original class with the byte stream(serialized object) in one package when sending it to another PC? Can the original class be like a DLL file?
