  - by Damir Horvat

  I'm very happy with By so far, only I have this one issue: When one process takes 1 or 2 hours to complete, all other jobs in the queue seem to wait for that one job to finish. Worse still is when uploading to a server which time's out regularly. My question: is Bj running jobs in parallel or one after another? Thank you, Damir

• Hierarchy inheritance

  - by reito

  I had faced the problem. In my C++ hierarchy tree I have two branches for entities of difference nature, but same behavior - same interface. I created such hierarchy trees (first in image below). And now I want to work with Item or Base classes independetly of their nature (first or second). Then I create one abstract branch for this use. My mind build (second in image below). But it not working. Working scheme seems (third in image below). It's bad logic, I think... Do anybody have some ideas about such hierarchy inheritance? How make it more logical? More simple for understanding? Image Sorry for my english - russian internet didn't help:) Update: You ask me to be more explicit, and I will be. In my project (plugins for Adobe Framemaker) I need to work with dialogs and GUI controls. In some places I working with WinAPI controls, and some other places with FDK (internal Framemaker) controls, but I want to work throw same interface. I can't use one base class and inherite others from it, because all needed controls - is a hierarchy tree (not one class). So I have one hierarchy tree for WinAPI controls, one for FDK and one abstract tree to use anyone control. For example, there is an Edit control (WinEdit and FdkEdit realization), a Button control (WinButton and FdkButton realization) and base entity - Control (WinControl and FdkControl realization). For now I can link my classes in realization trees (Win and Fdk) with inheritence between each of them (WinControl is base class for WinButton and WinEdit; FdkControl is base class for FdkButton and FdkEdit). And I can link to abstract classes (Control is base class for WinControl and FdkControl; Edit is base class for WinEdit and FdkEdit; Button is base class for WinButton and FdkButton). But I can't link my abstract tree - compiler swears. In fact I have two hierarchy trees, that I want to inherite from another one. Update: I have done this quest! :) I used the virtual inheritence and get such scheme (http://img12.imageshack.us/img12/7782/99614779.png). Abstract tree has only absolute abstract methods. All inheritence in abstract tree are virtual. Link from realization tree to abstract are virtual. On image shown only one realization tree for simplicity. Thanks for help!

• In VS2010, is there a way to know which application pool a given w3wp.exe is serving, to then decide

  - by Peter Mounce

  So I'm debugging some websites (one from trunk, one from branch) running locally, in separate apppools. I have trunk and branch solutions open in two VS instances. I'd like to debug trunk in one, and branch in the other. I'd like to know if there's a way to know which application pool each w3wp.exe is serving, to know which one is which when attaching the debugger.

• Why do some JVM/Linux Kernels show each java thread as a process and other not? How can I determine

  - by Jherico

  I have two machines, one running 2.4.18 and one running 2.4.20. Both run Java 1.5 build 13. On one machine (2.4.18), each thread shows up as a separate process in the ps output, and on the other the whole JVM shows up as one process. What is the distinguishing factor and can I control it?

• How to export each open project in Eclipse as its own JAR?

  - by Freiheit

  I have several projects open in an Eclipse workspace. Like so: com.harbl.project.one com.harbl.project.two com.harbl.project.three I would like to export those as JARs in a batch such that I wind up with the following JAR files: ./com.harbl.project.one.jar ./com.harbl.project.two.jar ./com.harbl.project.three.jar Is this possible with one of the Eclipse wizards or working sets? Is my only option to export each one individually?

• MouseWheel Event Fire

  - by Rahat

  I have a problem on calling my private method on MouseWheel event. In fact my mouse wheel event gets fired properly when i only increment a variable or display something in Title bar etc. But when i want to call a private method, that method gets called only one time which is not the requirement i want to call that method depending on the speed of scroll i.e. when scroll is done one time slowly call the private method one time but when the scroll is done in high speed call the private method more than one time depending on the scroll speed. For further explanation i am placing the sample code which displays the value of i in Title bar and add it in the Listbox control properly depending on the scroll speed but when i want to call the private method more than one time depending upon the scroll speed, that method gets called only one time. public partial class Form1 : Form { ListBox listBox1 = new ListBox(); int i = 0; public Form1() { InitializeComponent(); // Settnig ListBox control properties this.listBox1.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom) | System.Windows.Forms.AnchorStyles.Left) | System.Windows.Forms.AnchorStyles.Right))); this.listBox1.FormattingEnabled = true; this.listBox1.Location = new System.Drawing.Point(13, 13); this.listBox1.Name = "listBox1"; this.listBox1.Size = new System.Drawing.Size(259, 264); this.listBox1.TabIndex = 0; // Attaching Mouse Wheel Event this.listBox1.MouseWheel += new MouseEventHandler(Form1_MouseWheel); // Adding Control this.Controls.Add(this.listBox1); } void Form1_MouseWheel(object sender, MouseEventArgs e) { i++; this.Text = i.ToString(); this.listBox1.Items.Add(i.ToString()); // Uncomment the following line to call the private method // this method gets called only one time irrelevant of the // mouse wheel scroll speed. // this.LaunchThisEvent(); } private void Form1_Load(object sender, EventArgs e) { this.listBox1.Select(); } private void LaunchThisEvent() { // Display message each time // this method gets called. MessageBox.Show(i.ToString()); } } How to call the private method more than one time depending upon the speed of the mouse wheel scroll?

• Multiple depends in ant task

  - by glowcoder

  If I have three targets, one "all", one "compile" and one "jsps", how would I make "all" depend on the other two Would it be <target name="all" depends="compile,jsps"> or would it be <target name="all" depends="compile","jsps"> Or maybe something even different? I tried searching for example ant scripts to base it off of, but I couldn't find one with multiple depends. Thanks!

• Displaying bitmaps in relative positions

  - by JonF

  I'd like to put a couple images on a surfaceview. I understand that the screen sizes of android devices can vary, so I don't think I can just use an x y position or I might end up placing it off different screens. Say I want to put two boxes in the center of the screen, a blue one and a red one. The blue one is to the left of the red one. How can I accomplish that while accounting for different screen sizes?

• Perl daemon script for message queue hanging for 20 seconds after each process. Why?

  - by Mike Diena

  I have daemon script written in Perl that checks a database tables for rows, pulls them in one by one, sends the contents via HTTP post to another service, then logs the result and repeats (only a single child). When there are rows present, the first one is posted and logged immediately, but every subsequent one is delayed for around 20 seconds. There are no sleep()'s running, and I can't find any other obvious delays. Any ideas?

• CSS :nth-child Equation

  - by Meander365

  I have an unordered list and each li makes up one item in a two column layout: col1 col2 1 2 3 4 5 6 7 8 9 10 11 12 I need to have an alternating background colour for each item BUT NOT so each item in one column is the same. So : 1,4,5,8,9,11 will have one colour; and 2,3,6,7,10,12 will have another colour. Can this be achieved with one :nth-child rule? Thanks!

• In python beyond 'exec string' is there a way to 'import' using the db as a filesystem

  - by molicule

  Although it does not seem possible, I wanted to put this out there to see if others had some innovative solutions to 'dynamically loading and executing code in python' So if one saved code in a database, one could read it and 'exec it', however if one wanted to use it in a similar fashion to the filesystem, one would need to 'save and load the compiled .pyc' create an 'import dbimp' ala 'import imp' etc. any pointers? ideas? thoughts?

• Why do all of these methods of accessing an array work?

  - by bstullkid

  It seems to me that some of these should fail, but they all output what they are supposed to: $, = "\n"; %test = ( "one" => ["one_0", "one_1"], "two" => ["two_0", "two_1"] ); print @{$test{"one"}}[0], @{$test{"one"}}->[0], $test{"two"}->[0], $test{"one"}[1]; Why is this?

• wxWidgets: Show a window that was marked hidden in the XRC

  - by jdwieber

  I'm new to wxWidgets and DialogBlocks. I have a form that is created using DialogBlocks and saved as an XRC file. Part of the form has a vertical wxStaticBoxSizer into which is placed two wxScrolledWindow elements. I want to only show one at a time based on what data is to be shown to the user, so I have one marked hidden and left the other one visible. In code (C++), when I try to switch the display and show the widget that was hidden in the XRC and hide the one that was not, the one that I hide goes away fine, but the one that I want to show is not visible. If I resize the window however, it appears. Once it has appeard then I can switch back and forth with no issues. I tried many combinations of showing, enabling, invalidating, getting the sizer and calling RecalcSizes, refresh, layout, and some others. I tried them in different combinations too. Simply calling Show will allow me to toggle between the two, but only after I switch to the one that does not show initially and resize the window. From what I see in the docs. the issue is that wxSizer doesn't allocate space for hidden windows, but there is a flag that can be set to override that behavor. My problem is that DialogBlocks does not expose that feature, so if I manually edit the XRC file the modifation will be lost when I, or one of the other devs. saves some changes. Is ther a sequence of calls that I can make to tell the sizer to allocate space? The default OnResize handler does something to cause the sizer to allocate space, but I don't know what that is, or how to do it. This is the flag I found in the docs: wxRESERVE_SPACE_EVEN_IF_HIDDEN Normally wxSizers don't allocate space for hidden windows or other items. This flag overrides this behavior so that sufficient space is allocated for the window even if it isn't visible. This makes it possible to dynamically show and hide controls without resizing parent dialog, for example. This function is new since wxWidgets version 2.8.8 Thanks in advance.

• Remove a single non-unique value from a sequence in F#

  - by mavnn

  I have a sequence of integers representing dice in F#. In the game in question, the player has a pool of dice and can choose to play one (governed by certain rules) and keep the rest. If, for example, a player rolls a 6, 6 and a 4 and decides to play one the sixes, is there a simple way to return a sequence with only one 6 removed? Seq.filter (fun x -> x != 6) dice removes all of the sixes, not just one.

• Help me choose between XML or SQL Lite on android

  - by Ngetha

  I have an android app that periodically, say once a week downloads content from a server in XML. The content is used by the app, different Acitivities use different parts of the content. My question is a design one, should I save the data in SQlite or just keep it as an XML file, which one would be faster to read? The app can only use one content piece at a time, which means subsequent XML content downloads replace the old one.

• I need to change a zip code into a series of dots and dashes (a barcode), but I can't figure out how

  - by Maggie

  Here's what I've got so far: def encodeFive(zip): zero = "||:::" one = ":::||" two = "::|:|" three = "::||:" four = ":|::|" five = ":|:|:" six = ":||::" seven = "|:::|" eight = "|::|:" nine = "|:|::" codeList = [zero,one,two,three,four,five,six,seven,eight,nine] allCodes = zero+one+two+three+four+five+six+seven+eight+nine code = "" digits = str(zip) for i in digits: code = code + i return code With this I'll get the original zip code in a string, but none of the numbers are encoded into the barcode. I've figured out how to encode one number, but it wont work the same way with five numbers.
