    - by DaveDev
    I have an XML snippet as follows: <PerformancePanel> <LegalText> <Line id="300" /> <Line id="304" /> <Line id="278" /> </LegalText> </PerformancePanel> I'm using the following code to get an object: var performancePanels = new { Panels = (from panel in doc.Elements("PerformancePanel") select new { LegalTextIds = (from legalText in panel.Elements("LegalText").Elements("Line") select new List<int>() { (int)legalText.Attribute("id") }).ToList() }).ToList() }; The type of LegalTextIds is List<List<int>>.

  • How to check in which position (landscape or portrait) os the iPhone now?

    - by Knodel
    I have an app with a tab bar, and nav controllers in each tab. When user shakes the device, a UIImageView appears as a child view in the nav controller. But the UIImageView must contain a special image, depending on the device's current orientation. If I write just - (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation) if (interfaceOrientation == UIInterfaceOrientationPortrait|| interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { //Code } else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight||interfaceOrientation == UIInterfaceOrientationLandscapeLeft) { //Code } } The view just goes crazy if user rotated the device before shaking. Is there a method to get iPhones current orientation?

  • Using eachDirMatch to skip .svn folders

    - by algernon
    I'm writing a program which needs to traverse a set of directories. Tried to use the following code: file.eachDirMatch(/.*[^.svn]/){ //some code here } But that ended up match none of my directories. I realize this boils down figuring out the right regex hang head in shame but even after revisiting some Java Regular Expression documentation I thought this should work.

  • What's the easiest way to assign a string returned from the server to a javascript string?

    - by powerboy
    The following does not work: var js_str= '<?php echo $str_from_server; ?>'; The problem is that, $str_from_server can contain any characters. If it contains single quotes or line breaks or others, the above code will break. And I do not have access to the server-side code. What's the easiest way to "escape" the contents of $str_from_server into a javascript string, and then it can be restored later?

    I want to implement a code that loops inside an array that its size is set by the user that means that the size isn't constant. for example: A=[1,2,3,4,5] then I want the output to be like this: [1],[2],[3],[4],[5] [1,2],[1,3],[1,4],[1,5] [2,3],[2,4],[2,5] [3,4],[3,5] [4,5] [1,2,3],[1,2,4],[1,2,5] [1,3,4],[1,3,5] and so on [1,2,3,4],[1,2,3,5] [2,3,4,5] [1,2,3,4,5] Can you help me implement this code?

  • Python 3.2: How to pass a dictionary into str.format()

    - by Robert Dailey
    I've been reading the Python 3.2 docs about string formatting but it hasn't really helped me with this particular problem. Here is what I'm trying to do: stats = { 'copied': 5, 'skipped': 14 } print( 'Copied: {copied}, Skipped: {skipped}'.format( stats ) ) The above code will not work because the format() call is not reading the dictionary values and using those in place of my format placeholders. How can I modify my code to work with my dictionary?

  • the problem of redirecting stdout in c#

    - by Mher
    Could you please explain why the shell redirection doesn't work with System.Diagnostics.Process class? I am trying to redirect the output streams to file with the following snippet: Process p = new Process(); p.StartInfo = new ProcessStartInfo(); p.StartInfo.FileName = "java.exe"; p.StartInfo.Arguments = @"> c:\Temp\test.log 2>&1"; p.StartInfo.UseShellExecute = true; p.Start(); The similar code works without problems with Python. Reading the output streams programmatically doesn't seem a preferable solution in my case because there will be a bunch of processes launched by my application.

    A recent issue has arised. I have my local copy of code at ~/code/ directory where I made a git init. Whenever I copied a folder with files within it, git recognized folders and files normally.

Any ideas why this could be?

  • Is it a good practice to have trim in setter?

    - by zibi
    I'm doing a code review and I noticed such a code: @Entity @Table(name = "SOME_TABLE") public class SomeReportClass { @Column(name = "REPORT_NUMBER", length = 6, nullable = false) private String reportNumber; ..... public String getReportNumber() { return reportNumber; } public void setReportNumber(String reportNumber) { this.reportNumber = StringUtils.trimToNull(reportNumber); } } Every time I see trimming inside of a setter I feel that its not the clearest solution - what is the general practice with that issue?

  • C# massive insertion into data structures

    - by Seabass
    In C#, you can do the following: List registers = new List { 1, 2, 3, 4 }; This will produce a list with 1, 2, 3, and 4 in the list. Suppose that I am given a list from some function and I want to insert a bunch of numbers like the following: List register = somewhere(); register.Add(1); register.Add(2); register.Add(3); register.Add(4); Is there a cleaner way of doing this like the snippet above?

  • Problem with non-copyable classes

    - by DeadMG
    I've got some non-copyable classes. I don't invoke any of the copy operators or constructor, and this code compiles fine. But then I upgraded to Visual Studio 2010 Ultimate instead of Professional. Now the compiler is calling the copy constructor- even when the move constructor should be invoked. For example, in the following snippet: inline D3D9Mesh CreateSphere(D3D9Render& render, float radius, float slices) { D3D9Mesh retval(render); /* ... */ return std::move(retval); } Error: Cannot create copy constructor, because the class is non-copyable. However, I quite explicitly moved it.

  • How come $(this) is undefined after ajax call

    - by JohnnyQ
    I am doing an ajax request when an anchor tag is clicked with an ID set to href. Btw, this anchor tag is dynamically created. <a href="983" class="commentDeleteLink">delete</a> When the anchor tag is clicked the following code is executed: $('.commentDeleteLink').live('click', function(event) { event.preventDefault(); var result = confirm('Proceed?'); if ( result ) { $.ajax({ url: window.config.AJAX_REQUEST, type: "POST", data: { action : 'DELCOMMENT', comment : $('#commentText').val(), comment_id : $(this).attr('href') }, success: function(result) { alert($(this).attr('href')); //$(this).fadeOut(slow); } }); } }); When I tried to display $(this).attr('href') it says it's "undefined". What I really want to do is fadeOut the anchor tag but when I investigated the value of $(this) it is "undefined". What could be wrong with the snippet above?

  • How do I get this validationTextBox to focus?

    - by Anurag Chaudhury
    After performing an ajax request if the input in the form was wrong I am trying to get this validatationTextBox to be focussed on and display an indicator message showing the problem. The code is: dijit.byId("passwordField").focusNode.focus() The form element is as mentioned a validationTextBox. The matter that is confusing me even further is that before in dojo 1.5, this piece of code was simply dijit.byId("passwordField").focus() and this worked fine. How can I fix this?
