  • Scala return type for tuple-functions

    - by Felix
    Hello Guys, I want to make a scala function which returns a scala tuple. I can do a function like this: def foo = (1,"hello","world") and this will work fine, but now I want to tell the compiler what I expect to be returned from the function instead of using the built in type inference (after all, I have no idea what a (1,"hello","world") is) I thought I remembered the classname being something like Tuple3[Int,String,String] but that doesnt work for me. Suggestions? :D (ps: I love stack overflow!)

  • Form graphics not set when form loads

    - by Jimmy
    My form has a group box which contains two overlapping rectangles. The form's other controls are two sets of four numeric up down controls to set the rectangles' colors. (nudF1,2,3 and 4 set the rectangle that's in front, and nudB1,2,3 and 4 set the rectangle that's behind.) Everything works fine, except that the rectangles do not display the colors set in the numeric up downs when the form first loads. The numeric up down controls' ChangeValue events all call the ShowColors() method. The form's Load event calls the csColorsForm_Load() method. Any suggestions? namespace csColors { public partial class csColorsForm : Form { public csColorsForm() { InitializeComponent(); } private void csColorsForm_Load(object sender, EventArgs e) { this.BackColor = System.Drawing.Color.DarkBlue; SetColors(sender, e); } private void SetColors(object sender, EventArgs e) { Control control = (Control)sender; String ctrlName = control.Name; Graphics objGraphics; Rectangle rect1, rect2; int colorBack, colorFore; objGraphics = this.grpColor.CreateGraphics(); // If calling control is not a forecolor control, paint backcolor rectangle if (ctrlName.Substring(0,4)!="nudF") { colorBack = int.Parse(SetColorsB("nudB"), NumberStyles.HexNumber); SolidBrush BrushB = new SolidBrush(Color.FromArgb(colorBack)); rect1 = new Rectangle(this.grpColor.Left, this.grpColor.Top, this.grpColor.Width, this.grpColor.Height); objGraphics.FillRectangle(BrushB, rect1); } // Always paint forecolor rectangle colorFore = int.Parse(SetColorsB("nudF"), NumberStyles.HexNumber); SolidBrush BrushF = new SolidBrush(Color.FromArgb(colorFore)); rect2 = new Rectangle(this.grpColor.Left, this.grpColor.Top, this.grpColor.Width, this.grpColor.Height); objGraphics.FillRectangle(BrushF, rect2); objGraphics.Dispose(); } private string SetColorsB(string nam) { string txt=""; for (int n = 1; n <= 4; ++n) { var ud = Controls[nam + n] as NumericUpDown; int hex = (int)ud.Value; txt += hex.ToString("X2"); } return txt; } private void btnClose_Click(object sender, EventArgs e) { this.Close(); } } }

There are multiple items starting with the same letter Thanks

  • What does this `_time_independent_equlas` mean?

    - by Satoru.Logic
    In the tornado.web module there is a function called _time_independent_equals: def _time_independent_equals(a, b): if len(a) != len(b): return False result = 0 for x, y in zip(a, b): result |= ord(x) ^ ord(y) return result == 0 It is used to compare secure cookie signatures, and thus the name. But regarding the implementation of this function, is it just a complex way to say a==b?

  • How do I get the set of all letters in Java/Clojure?

    - by Jason Baker
    In Python, I can do this: >>> import string >>> string.letters 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ' Is there any way to do something similar in Clojure (apart from copying and pasting the above characters somewhere)? I looked through both the Clojure standard library and the java standard library and couldn't find it.

  • Declare Locally or Globally in Delphi?

    - by lkessler
    I have a procedure my program calls tens of thousands of times that uses a generic structure like this: procedure PrintIndiEntry(JumpID: string); type TPeopleIncluded = record IndiPtr: pointer; Relationship: string; end; var PeopleIncluded: TList<TPeopleIncluded>; PI: TPeopleIncluded; begin { PrintIndiEntry } PeopleIncluded := TList<TPeopleIncluded>.Create; { A loop here that determines a small number (up to 100) people to process } while ... do begin PI.IndiPtr := ...; PI.Relationship := ...; PeopleIncluded.Add(PI); end; DoSomeProcess(PeopleIncluded); PeopleIncluded.Clear; PeopleIncluded.Free; end { PrintIndiEntry } Alternatively, I can declare PeopleIncluded globally rather than locally as follows: unit process; interface type TPeopleIncluded = record IndiPtr: pointer; Relationship: string; end; var PeopleIncluded: TList<TPeopleIncluded>; PI: TPeopleIncluded; procedure PrintIndiEntry(JumpID: string); begin { PrintIndiEntry } { A loop here that determines a small number (up to 100) people to process } while ... do begin PI.IndiPtr := ...; PI.Relationship := ...; PeopleIncluded.Add(PI); end; DoSomeProcess(PeopleIncluded); PeopleIncluded.Clear; end { PrintIndiEntry } procedure InitializeProcessing; begin PeopleIncluded := TList<TPeopleIncluded>.Create; end; procedure FinalizeProcessing; begin PeopleIncluded.Free; end; My question is whether in this situation it is better to declare PeopleIncluded globally rather than locally. I know the theory is to define locally whenever possible, but I would like to know if there are any issues to worry about with regards to doing tens of thousands of of "create"s and "free"s? Making them global will do only one create and one free. What is the recommended method to use in this case? If the recommended method is to still define it locally, then I'm wondering if there are any situations where it is better to define globally when defining locally is still an option.

  • Howto check if two hosts are the same

    - by Michael Stoll
    Hi, I just came across an issue, where I had to check if a path points into a windows share. Part of this problem is to check if host A is the same as host B. Where host A and host B can be one of the following {IPv4-Address, IPv6-Address, Hostname, FQDN}. As I do not need to be exact it's enough to resolve and compare the IP-Addresses in my case. But is there, theoretically, a method to check if the hosts are the same?

  • How do I ensure jQuery ajax call does not send a local copy of file?

    - by Tommy
    $.ajax({ type: 'GET', url: "string.txt", cache: false, success: function(str){ alert("Data is: "+ str); } }); In this example, string.txt is still sent to the cache (\Temporary Internet Files) How do I ensure that the file is not sent - read from the server only? Am I missing an option? I set cache to false but that does not block it from being sent to client. For example, ajax POST does not send a local copy..... Thanks

  • Inconsistent email formatting with inline css created using Javamail

    - by user1816183
    Okay, so I have a program that sends an email when it is finished running. I use inline css to format the email. This was working up until yesterday however now I am seeing different formats depending on which email account I view the email in. It coincides with an upgrade from Selenium 2.35.0 to 2.37.0 however I don't think this is my issue since I rolled back to 2.35.0 and it still happens. package tests; import java.util.Properties; import javax.mail.Message; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; public class TESTTEST { public static void main(String[] args) throws Exception { Properties props = new Properties(); props.put("mail.smtp.host","xxx.xxx.xxx.xxx"); Session session = Session.getInstance(props); String emailFrom="[email protected]"; String emailTo1="[email protected]"; MimeMessage message = new MimeMessage(session); message.setSubject("Testing HTML Email"); message.setFrom(new InternetAddress(emailFrom)); String htmlBody = "<STYLE>body {font-family:sans-serif,arial,helvetica,sans-serif;font-size:9pt;}" +"TABLE {border-collapse:collapse;border:1px solid black;}" +"TH {background-color:grey;color:white;padding:5px;border:1px solid black;font-size:9pt;}" +"TD {padding:5px;border:1px solid black;font-size:9pt;}" +"H3 {font-size:12pt;}" +".PASSED {background-color:#00FF00}" +".FAILED {background-color:#FF0000}" +".SKIPPED {background-color:#DEDEDE}" +".ITALIC {font-style:italic}" +"</STYLE>" + "<TABLE><TR><TD CLASS=PASSED>FAIL</TD><TD STYLE=background-color:#FF0000>FAIL</TD></TR></TABLE>"; message.setContent(htmlBody, "text/html; charset=ISO-8859-1"); message.addRecipient(Message.RecipientType.TO,new InternetAddress(emailTo1)); Transport.send(message,message.getRecipients(Message.RecipientType.TO)); System.out.println(htmlBody); System.out.println("Email Sent"); } } When I view the email in Hotmail/Outlook.com, it looks fine In Gmail In Lotus Notes Anybody able to help?
