  • Does my function right on python?

    - by Ali Ismayilov
    Write a function which takes a string argument, and creates and returns an Employee object containing details of the employee specified by the string. The string should be assumed to have the format 12345 25000 Consultant Bart Simpson The first three items in the line will be the payroll number, salary and job title and the rest of the line will be the name. There will be no spaces in the job title but there may be one or more spaces in the name. My function: def __str__(self): return format(self.payroll, "d") + format(self.salary, "d") + ' ' \ + self.jobtitle + self.name

  • Reset selection of wx.lib.calendar.Calendar control?

    - by Joseph
    I have a wx.lib.calendar.Calendar control (not wx.lib.calendar.CalendarCtrl!). I am selecting a number of days using the following function call: self.cal.AddSelect([days], 'green', 'white') This works, and draws the days highlighted. However, I cannot work out how to reverse this (i.e., clear the selection so the days go back to their normal colouring). Any hints, please?

  • Java JSpinner Prevent Letter Insertion

    - by asmo
    A JSpinner is used to store a number in my application (with a SpinnerNumberModel). As expected, the spinner doesn't allow invalid characters (letters, symbols, etc.) to be stored. However, those characters do appear in the spinner component when I type them in. As soon as I switch the focus to another component, they disappear. Is there a way to prevent invalid characters from appearing in the spinner?

  • Is there a way to combine IN and LIKE in MySQL?

    - by abeger
    I'm currently running a query like this: SELECT * FROM email WHERE email_address LIKE 'ajones@%' OR email_address LIKE 'bsmith@%' OR email_address LIKE 'cjohnson@%' The large number of OR's bothers me. Is there a way to condense this up with something akin to an IN operator, e.g.: SELECT * FROM email WHERE email_address LIKE ('ajones@%', 'bsmith@%', 'cjohnson@%') Or is this just wishful thinking?

  • What percent of web sites use JavaScript?

    - by Claudiu
    I'm wondering just how pervasive JavaScript is. This article states that 73% of websites they tested rely on JavaScript for important functionality, but it seems to me that the number must be larger. Have any surveys been done on this topic? Maybe a better way to phrase this question is - are there any sites that don't use JavaScript? EDIT: By 'use', I don't necessarily mean "rely on for important functionality" - that was just the statistic that one article gave.

  • Step math function

    - by ekapek
    Hi I need function which returns: for any number from range = result [0.001,0.01) => 0.01 [0.01,0.1) => 0.1 [0.1,1) => 1 [1,10) => 10 [10,100) => 100 etc. My first idea was to use if, but this the worst way. Is there a simple solution?

  • What is the best way to findout whether a date falls in particular range?

    - by Amit
    I tried the following DateTime start = Convert.ToDateTime(TextBox1.Text); DateTime end = Convert.ToDateTime(TextBox2.Text); if (DateTime.Now.Date == start.Date || DateTime.Now.Date == end.Date || (DateTime.Now >= start.Date && DateTime.Now <= end.Date)) { lblResult.Text = "true"; } else { lblResult.Text = "false"; } This verifies if the date range is one day also. Any way to reduce the number of conditions above?

    I need a regular in expression in PHP that I can plug into preg_match_all and find if an @ sign and any character number or letter follows right after that. So if I put "@patrick hello there" it will come up true, if I put in "I saw her @ the mall" it will be false. Thank you :)

    Hey all, I've created a game which gives a score at the end of the game, but the problem is that this score is sometimes a number with a lot of digits after the decimal point (like 87.124563563566). How would I go about rounding up or down the value so that I could have something like 87.12? Thanks!

  • In a web farm environment, should we base the system date/time to the web servers or the database se

    - by leypascua
    Assuming there are a number of load-balanced web servers in a web farm, is it safe to use DateTime.Now in the application code for getting the system date/time or should we leave this responsibility to the database server? Would there be a chance that machine date/time settings on all servers in the webfarm are out of sync? If date/time will be the responsible of the DBMS, how will this strategy work if we have load-balanced replicated DBs?

  • Why does dynamic array always double by a factor of 2?

    - by Phoenix
    I was wondering how does one decide the resizing factor by which dynamic array resizes ? On wikipedia and else where I have always seen the number of elements being increased by a factor of 2? Why 2? Why not 3? how does one decide this factor ? IF it is language dependent I would like to know this for Java.

  • How do I use multiple arguments from an array to construct an execl() call in C?

    - by chucknelson
    I have a string array in C named args[] - now how can I use this list of arguments to construct a proper call to execl()? So if the array contains: {"/bin/ls","ls","-a","-l"} ...how can I eventually construct an execl() call that is: execl("/bin/ls","ls","-a","-l",NULL); I must be thinking about this wrong, as I can't find anything online, just talk about defining functions that can take a variable number of arguments.

  • Dedicating all processor power to a task

    - by Yktula
    Let's say we have a very processor-intensive task at hand which could be effectively parallelized. How can we dedicate all or almost all available processor power to performing that task? The task could be a variety of things, and iterative Fibonacci number generation that saves recorded numbers would be just one example.

  • Understanding EXE Internals

    - by Steve
    I was attempting to install an exe that requires a serial number before the install, which the vendor has not provided to us yet. This got my wheels turning about whether there is any information that can be gained from viewing an exe using a hex editor/VI/etc? Using VI to view an exe, I can see some sections of plain text, but it is difficult to determine what it refers to without any context around it. Is it possible to determine any information by reading an exe? Thanks

  • Converting javafx.util.Properties to a HashMap

    - by Mozez
    Hello, I was wondering if there is an easy way to convert the javafx.util.Properties object to a java.util.HashMap. There is the obvious way of getting each value from the Properties object and putting it in a Map. But with a large number of properties it seems like there should be a way of just getting the Map that backs javafx.util.Properties (if it is a Map). Thanks in advance for any suggestions.
