  • Entity Framework - Store parent reference on child relationship (one -> many)

    - by contactmatt
    I have a setup like this: [Table("tablename...")] public class Branch { public Branch() { Users = new List<User>(); } [Key] public int Id { get; set; } public string Name { get; set; } public List<User> Users { get; set; } } [Table("tablename...")] public class User { [Key] public int Id {get; set; } public string Username { get; set; } public string Password { get; set; } [ForeignKey("ParentBranch")] public int? ParentBranchId { get; set; } // Is this possible? public Branch ParentBranch { get; set; } // ??? } Is it possible for the User to know what parent branch it belongs to? The code above is not working. Entity Framework version 5.0 .NET 4.0 c#

  • Bash, Concatenating 2 strings to reference a 3rd variable

    - by Im Fine
    I have a bash script I am having some issues with concatenating 2 variables to call a 3rd. Here is a simplification of the script, but the syntax is eluding me after reading the docs. server_list_all="server1 server2 server3"; var1 = "server"; var2 = "all"; echo $(($var1_list_$var2)); This is about as close as I get to the right answer, it acknowledges the string and tosses an error on tokenization. syntax error in expression (error token is "server1 server2 server3.... Not really seeing anything in the docs for this, but it should be doable. EDIT: Cleaned up a bit

  • Best way to convert log files (*.txt) to web-friendly files (*.html, *.jsp, etc)?

    - by prometheus
    I have a bunch of log files which are pure text. Here is an example of one... Overall Failures Log SW Failures - 03.09.2010 - /logs/swfailures.txt - 23 errors - 24 warnings HW Failures - 03.09.2010 - /logs/hwfailures.txt - 42 errors - 25 warnings SW Failures - 03.10.2010 - /logs/swfailures.txt - 32 errors - 27 warnings HW Failures - 03.10.2010 - /logs/hwfailures.txt - 11 errors - 31 warnings These files can get quite large and contain a lot of other information. I'd like to produce an HTML file from this log that will add links to key portions and allow the user to open up other log files as a result... SW Failures - 03.09.2010 - <a href="/logs/swfailures.txt">/logs/swfailures.txt</a> - 23 errors - 24 warnings This is greatly simplified as I would like to add many more links and other html elements. My question is -- what is the best way to do this? If the files are large, should I generate the html before serving it to the user or will jsp do? Should I use perl or other scripting languages to do this? What are your thoughts and experiences?

  • How to copy referenced assembly's dependecies to ASP.NET output bin folder?

    - by LD2008
    Hi all, In Visual Studio 2010, I have project A (asp.net application). Project A references project B (class library). Project B references assembly C (direct reference to a DLL). When building project A, only project A and project B binaries are present in the /bin directory of project A, but not the assembly C. Why is that? If project B depends on assembly C, why is assembly C not copied together to the output folder? "Copy local" is already set to "true" for assembly C. Any information would be appreciated. Thanks!

  • web-development: how do you usually handle the "under costruction" page"?

    - by Patrick
    hi, I was wondering what's the best way to switch a website to a temporary "under costruction" page and switch it back to the new version. For example, in a website, my customer decided to switch from Joomla to Drupal and I had to create a subfolder for the new CMS, and then move all the content to the root folder. 1) Moving all the content back to the root folder always create some problems with file permissions, links, etc... 2) Creating a rewrite rule in .htaccess or forward with php is not a solution because another url is shown including the top folder. 3) Many host services do not allow to change the root directory, so this is not an option since I don't have access to apache config file. Thanks

  • int vs const int&

    - by Valdo
    I've noticed that I usually use constant references as return values or arguments. I think the reason is that it works almost the same as using non-reference in the code. But it definitely takes more space and function declarations become longer. I'm OK with such code but I think some people my find it a bad programming style. What do you think? Is it worth writing const int& over int? I think it's optimized by the compiler anyway, so maybe I'm just wasting my time coding it, a?

  • C++, is it possible to obtain the dimension of an array?

    - by aaa
    hi. Suppose I have some pointer, which I want to reinterpret as static dimension array reference: double *p; double (&r)[4] = ?(p); // some construct? // clarify template< size_t N> void function(double (&a)[N]); ... double *p; function(p); // this will not work. // I would like to cast p as to make it appear as double[N] Is it possible to do so? how do I do it?

  • jQuery Reference First Column in HTML Table

    - by Vic
    I have a table where all of the cells are INPUT tags. I have a function which looks for the first input cell and replaces it with it's value. So this: <tr id="row_0" class="datarow"> <td><input class="tabcell" value="Injuries"></td> <td><input class="tabcell" value="01"></td> becomes this: <tr id="row_0" class="datarow"> <td>Injuries</td> <td><input class="tabcell" value="01"></td> Here is the first part of the function: function setRowLabels() { var row = []; $('.dataRow').each(function(i) { row.push($('td input:eq(0)', this).val() + ' - '); $('td input:eq(0)', this).replaceWith($('td input:eq(0)', this).val()); $('td input:gt(0)', this).each(function(e) { etcetera But when the page reloads, the first column is not an input type, so it changes the second column to text too! Can I tell it to only change the first column, no matter what the type is? I tried $('td:eq(0)', this).replaceWith($('td:eq(0)', this).val()); but it does not work. Any suggestions appreciated! Thanks

  • Reference to fnc.

    - by atch
    Hi guys, Is there a way in java to do something like this: void fnc(void Reference_to_other_func()); What I'm trying is basically I have number of places where I need to display this same text to the user and the only difference is which method is invoked after this text. So for example instead of writing: System.out.println("Hello"); f1(); //in some other place System.out.println("Hello"); f2(); //etc I would like to define one function: public void f(void Reference_to_other_func()) { System.out.println("Hello"); Reference_to_other_func();//HERE I'M INVOKING } and then instead of repeating this whole code I could write something like this: f(f1); //in some other place f(f2) //etc. Thanks for answers

  • pass by const reference of class

    - by small_potato
    void foo(const ClassName &name) { ... } How can I access the method of class instance name? name.method() didn't work. then I tried: void foo(const ClassName &name) { ClassName temp = name; ... .... } I can use temp.method, but after foo was executed, the original name screwed up, any idea? BTW, the member variable of name didn't screwed up, but it was the member variable of subclass of class screwed up.

  • How to invoke a Servlet (doGet) in a web application on startup?

    - by Dan
    I need to invoke a Servlet on application startup since it contains some application initialization logic. I know I can set load-on-startup configuration, but this will only invoke Servlet’s init method. I need to invoke a doGet method and pass some Url parameters to it. Servlet doGet method expects ServletRequest and ServletResponse objects. Also, since this is clustered application, I need to know exactly what node I am accessing (since one option is just to open a socket and invoke a Servlet). What is the best option to perform this?

  • How to go about finding ad-hoc development work on the web?

    - by DaveDev
    I'm wondering if its possible to find supplementary development work on line? I have some time available to me in the evenings and I thought it might be good to use it productively. It'd be great if there was a site that I could apply to do some ad-hoc coding for anyone who needs it. Something like 'I need a class that does XY & Z', and I could do that. Is there anything like this out there? Can somebody supply me with some info? Thanks
