  • How to resolve Resharper's "unused property" warning on properties solely for Display/Value Members?

    - by JYelton
    I have defined two properties "Name" and "ID" for an object which I use for the DisplayMember and ValueMember of a ComboBox with a BindingList datasource. I recently installed Resharper to evaluate it. Resharper is giving me warnings on the object that the two properties are unused. Sample code: BindingList<ClassSample> SampleList = new BindingList<ClassSample>(); // populate SampleList cmbSampleSelector.DisplayMember = "Name"; cmdSampleSelector.ValueMember = "ID"; cmbSampleSelector.DataSource = SampleList; private class ClassSample { private string _name; private string _id; public string Name // Resharper believes this property is unused { get { return _name; } } public string ID // Resharper believes this property is unused { get {return _id; } } public ClassSample(string Name, string ID) { _name = Name; _id = ID; } } Am I doing something wrong or is Resharper clueless about this particular usage?

  • How often should a programmer communicate with management?

    - by George Johnston
    I struggle with finding a good medium on communication. In our jobs, it seems like it's very easy to get lost in code and lose track of time. It also seems kind of ridiculous to send out updates for every tiny task. Even though I am working very hard on getting things done, in a company that has very active communication between other branches, it tends to look bad for me when I'm not constantly updating my status. However, if I'm working on a 3-4 hour project, I'm not going to update management for every single line of code that I output. Broad I know, depends on the people, company, etc, but what would be a good general rule of thumb for effective communication?

  • Is there a way to be notified when the user makes changes in a wxStyledTextCtrl?

    - by George Edison
    I have a wxWidgets application that has a wxStyledTextCtrl. But for the life of me, I cannot figure out how to get notified of modification events. I have the following code: void CMainWindow::OnDocumentModified(wxStyledTextEvent & event) { wxString msg; msg << event.GetModificationType(); wxMessageBox(msg); } This gets called for EVT_STC_MODIFIED. When I run the application and press a key, the message box displays 1040 and 8209. When I call SetText the same two messages are displayed. How can I differentiate between user events and programmatically-generated events?

  • Why Solr admin query page interprets UTF-8 as ISO-8859-1

    - by Scott Chu
    I deploy a war to my Tomcat 6.0.35 on Win7 64bit and when I use full-interface query page (I mean form.jsp) in Solr Admin to query 2 Chinese character (say it's C1C2) , the debug info shows: <lst name="debug"> <str name="rawquerystring">æ°è</str> <str name="querystring">æ°è</str> <str name="parsedquery">NEWSID:æ°è</str> <str name="parsedquery_toString">NEWSID:æ°è</str> ... You can see C1C2 becomes æ°è. I deploy same war file to Tomcat on Linux or on another Win7 64bit of my colleagues' computer, the encoding acts well. Does anyone know why and how can I avoid this problem? Thanks in advance!

  • How to set result of function as global variable.

    - by George
    I'm sure this is really simple and I'm drawing a giant blank, but how do you set the result of a function as a global variable? Example, I want to set the first "color" in array "colors" as global variable "color" (I know the example doesn't make much practical sense, but it's just to illustrate my question): var color = ""; function selectColor () { var colors = ["blue","red","green","yellow"]; var color = colors[0]; return color; } window.onload = function () { selectColor (); alert(color); }

  • How to authenticate users against a Windows AD?

    - by Potinos
    I've a JSF-Hibernate web application. I need to authenticate users against a Windows AD and the web application should only allow logins from members of group X, otherwise it should redirect to an error page. How can I configure this? Also, I would like to display the name of the logged-in user on all pages, not the name of the Windows user of the server machine. I have tried the System.property("user.name") for this, but this only returns the name of the Windows user of the server name.

  • How do I dump arrays in a nice orderly fashion?

    - by George
    Whenever I use print_r or var_dump they come out all sloppy and in one line instead of formatted like I see so many people and the actual php.net site being able to achieve. What do I do to get them like this - Array ( [a] => apple [b] => banana [c] => Array ( [0] => x [1] => y [2] => z ) ) Instead of this Array([a] => apple [b] => banana [c] => Array ( [0] => x [1] => y [2] => z )) (Pretty sure it comes out even messier than that I was just deleting whitespace by hand.)

  • VS2010 and CSS: What is the best way to position a single form control

    - by George
    OK, I have a ton of controls on my page that I need to individually place. I need to set a margin here, a padding there, etc. None of these particular styles that I want to apply will be applied to more than control. What is the bets practice for determining at which level the style is placed, etc? OK, my choices are 1) External CSS file 1A) Using ClientIdMode = Auto (the default) I could assign a unique CssClass value to the ASP.NET control and, in the external CSS file, create a class selector that would only be applied to that one control. 1B) User Client ID = Predicatable In the external CSS file, I could determine what the ID will be for the controls of interest and create an ID selector (#ControlID{Style} ). However, I fear maintenance issues due to including/removing parent containers that would cause the ID to change. 1C) User Client ID = Static. I could choose static IDs for the controls such that I minimize the likelihood of a clash with auto generated IDs (perhaps by prefixing the ID with "StaticID_" and use an external stylesheet with ID selectors. 2) I could place the style right on the control. The only disadvantage here, as I see it, is that style info is brought down each time instead of being cached , which is what I'd get using an external CSS. If a style isn't resused, I personally don't see much benefit to placing it in an external file, though please explain why if you disagree. Is there moire of a reason that "It's nice to have all the CSS in one place?"

  • Accessing variablss through a different class within the constructor of latter classes of an object

    - by Haxed
    In the code below, I've added two lines that print output. The first line prints junk as usual, but surprisingly the second one gives me a compilation error. Why? class Student { private String name; public Student(String name){ this.name = name; } public String getName(){ return name; } } class StudentServer { public StudentServer(){ Student[] s = new Student[30]; s[0] = new Student("Nick"); // LINE 01: This compiles, although prints junk System.out.println(s[0]); // LINE 02: I get a error called cannot find symbol System.out.println(s[0].getName()); } public static void main(){ new StudentServer(); } } Many Thanks

  • Using Python, How to copy files in 'temporary internet files' folder in Windows

    - by pythBegin
    I am using this code to find files recursively in a folder , with size greater than 50000 bytes. def listall(parent): lis=[] for root, dirs, files in os.walk(parent): for name in files: if os.path.getsize(os.path.join(root,name))>500000: lis.append(os.path.join(root,name)) return lis This is working fine. But when I used this on 'temporary internet files' folder in windows, am getting this error. Traceback (most recent call last): File "<pyshell#4>", line 1, in <module> listall(a) File "<pyshell#2>", line 5, in listall if os.path.getsize(os.path.join(root,name))>500000: File "C:\Python26\lib\genericpath.py", line 49, in getsize return os.stat(filename).st_size WindowsError: [Error 123] The filename, directory name, or volume label syntax is incorrect: 'C:\\Documents and Settings\\khedarnatha\\Local Settings\\Temporary Internet Files\\Content.IE5\\EDS8C2V7\\??????+1[1].jpg' I think this is because windows gives names with special characters in this specific folder... Please help to sort out this issue.

  • Appropriate collection for variable-depth list?

    - by George R
    If I wanted to have a collection that described the (recursive) contents of a root directory, including directories and files, how would I store them? Or do I need to come up with an object that holds: -Current directory -Parent directory -Files in directory ..and slap them all in one big list and manually work out the relationship at runtime from each entries Parent directory.

  • What is the future of C++?

    - by George Edison
    Given the rise in popularity of C# and others, (which you can point out in the comments) what future does C++ have? Consider that most OS code is a mix of Asm/C/C++ and a lot of FOSS still use it. Also consider the upcoming C++0x standard that brings a few changes to the mix.

  • Why isn't IE displaying this alert()?

    - by George Edison
    I have the following piece of code: // setup the AJAX request var pageRequest = false; if(window.XMLHttpRequest) pageRequest = new XMLHttpRequest(); else if(window.ActiveXObject) pageRequest = new ActiveXObject("Microsoft.XMLHTTP"); // callback pageRequest.onreadystatechange = function() { alert('pageRequest.readyState: ' + pageRequest.readyState + '\npageRequest.status: ' + pageRequest.status); } pageRequest.open('POST','ajax.php',true); // q_str contains something like 'data=value...' pageRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); pageRequest.setRequestHeader("Content-length", q_str.length); pageRequest.setRequestHeader("Connection", "close"); pageRequest.send(q_str); This works fine in Chrome, but IE chokes on it, spitting out an "Unspecified error." and it points to the line with the alert() in it. Why can't it display the alert?

  • Is it wise to rely on default features of a programming language?

    - by George Edison
    Should I frequently rely on default values? For example, in PHP, if you have the following: <?php $var .= "Value"; ?> This is perfectly fine - it works. But what if assignment like this to a previously unused variable is later eliminated from the language? (I'm not referring to just general assignment to an unused variable.) There are countless examples of where the default value of something has changed and so much existing code was then useless. On the other hand, without default values, there is a lot of code redundancy. What is the proper way of dealing with this?

  • Select one column from a row in hibernate

    - by ComfortablyNumb
    I am trying to do a simple query to get a unique result back in hibernate here is my code. public String getName(Integer id) { Session session = getSessionFactory().openSession(); String name = (String)session.createSQLQuery("SELECT name FROM users WHERE user_id = :userId").setParameter("userId", id).uniqueResult(); return name; } The name that is being returned is stored as HTML text that includes html syntacx language. I think this is what is causing the problem but it doesnt make sense I just want to return it as a string. It is only happening on this one field name, I can get every other field in the row but this one it gives me the error. I am getting an exception. The exception I am getting is No Dialect mapping for JDBC type: -1; nested exception is org.hibernate.HibernateException How do you query for a specific column on a row in hibernate?

  • What speech libraries are available in Linux?

    - by George Edison
    When it comes to TTS (text-to-speech) libraries in Linux, what choices do developers have? What libraries ship with the majority of distros? Are there minimal libraries? What functionality does each library offer? I'm approaching this primarily from a C++ point of view, although Python would suit me too.
