  • JQUERY ajax passing null value from MVC View to Controller

    - by Piyush Sardana
    hi guys i'm posting some data to controller using jquery ajax, but i am getting null values in my controller, jQuery code is: $('#registerCompOff').click(function() { var compOff = []; $('div').each(function() { var curRow = {}; curRow.Description = $(this).find('.reason').val(); curRow.CompOffDate = $(this).find('.datefieldWithWeekends').val(); if (curRow.Description != null && curRow.CompOffDate != null) { compOff.push(curRow); } }); $.ajax({ type: 'POST', url: this.href, dataType: 'json', data: compOff }); return $('form').valid(); });? compOff is not null I have checked that... controller is: [HttpPost] public ActionResult RegisterCompOff(RegisterCompOff[] registerCompOff) { //return View(); } can you tell me where i'm going wrong?

  • Passing CMD Results to Variable in a Batch File

    - by TripleNad
    I am trying to install an application and a group of services using PSTools, but I want to take into account that the computer I am trying to connect to may be turned off or on a different network, which is not reachable from the internal network. Basically if the machine is not able to be accessed through the admin share, this is the message that I am getting: Couldn't access MachineName: The network path was not found. Make sure that the default admin$ share is enabled on MachineName. This is the syntax I am using to try to capture the "Error Message" and then report back that if installation was successful or not (depending on if it can contact the machine) @echo off set /p name=What is the machine name?: psexec.exe \\\%name% -u *useraccount* -p *password* \\\ServerName\installation.bat FOR /F "tokens=*" %%A IN ('COMMAND ^| FIND "Couldn't access"') DO SET Error=%%A If "%Error%"=="Couldn't access" ECHO Installation Failed. Else ECHO Installtion complete. Pause exit Currently it hangs right at the point it's defining the Error Variable. Can't quite figure out what I am going wrong here.

  • Reflection for Class of generic parameter in Java?

    - by hatboysam
    Imagine the following scenario: class MyClass extends OtherClass<String>{ String myName; //Whatever } class OtherClass<T> { T myfield; } And I am analyzing MyClass using reflection specifically (MyClass.class).getDeclaredFields(), in this case I will get the following fields (and Types, using getType() of the Field): myName --> String myField --> T I want to get the actual Type for T, which is known at runtime due to the explicit "String" in the extends notation, how do I go about getting the non-genetic type of myField?

  • How do I form a Rails link_to with custom field value as parameter

    - by rwheadon
    I have an invoice form where I'm giving the user opportunity to apply coupons to the invoice total. These coupons are held in another Model and I am going to do a lookup on the Coupon code (something like "20OFFONFRIDAY") which I will use to find what the restrictions and benefits of the coupon. (and to see if it even exists at all) The invoice does not have "coupon_code" on it so I hand forged the field onto my form with html: <% if (@invoice.status == 'new') %> <input id="coupon_code" name="coupon_code" type="text"/> <% end %> and I am calling a controller method with link_to and would like something like the following jquery enhanced link_to to work: <%= link_to "Apply Coupon", { :controller=>"invoices", :id=>@invoice.id, :coupon_code=>$('.coupon_code').val(), :action=>"apply_coupon_code" }, :method=>"post" %> ^formatted for easier reading Then inside my "apply_coupon_code" method I will go off to a couple other models and perform business logic before returning the updated invoice page. ...but maybe it's a pipe dream. I guess if push came to shove I could add the "coupon_code" field to my invoice model (even though it's persisted elsewhere.) so it's part of the entity and thus easily available on my form to send back into a controller, but I just hate adding a column to make a coupon validation easier. I figured I'd ping stackoverflow before taking that path.

  • passing info from facebook to UITabBarController

    - by EquinoX
    When my app first start, it shows up a main page showing to login to facebook and then it goes to the UITabBarController. The code that I have in my app delegate is the following: //this is the .h @interface NMeAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; MainViewController *controller; UITabBarController *tabBar; } @property (nonatomic, retain) IBOutlet UITabBarController *tabBar; @property (nonatomic, retain) MainViewController *controller; @property (nonatomic, retain) IBOutlet UIWindow *window; @end //this is the .m of the app delegate #import "NMeAppDelegate.h" @implementation NMeAppDelegate @synthesize window; @synthesize tabBar; @synthesize controller; #pragma mark - #pragma mark Application lifecycle - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. controller = [[MainViewController alloc] init]; [window addSubview:tabBar.view]; [window addSubview:controller.view]; [window makeKeyAndVisible]; return YES; } Inside of MainViewController, I actually have a Facebook * facebook object, which basically has all of the information that I need. Every information that I need for this apps is queried in the MainViewController. The problem is that after getting this info and now I am in the UITabViewController... how do I get those information that I already queried facebook for? I have a class called UserInfo as well, which basically has everything essential I need. I need to have the info from UserInfo so that the other ViewController in the UITabBarController have access to it.... I hope my question makes sense

  • Passing report values to a query

    - by Beavis
    I'm a novice with Microsoft Access as my background is mostly .NET. I'm sure what I'm trying to accomplish is dead simple but I need some direction. I have a report and a query. The query returns a single numeric value based on a single numeric criteria. Select total from table where id = [topic] I have placed a text box on my report so I can feed the id to this query and in return get the total. It seems like DLookUp is what I want but no matter how I construct it, I get an "#Error" in the text box when I run the report. Currently my DLookUp looks like this (I just hard-coded now for simplicity): =DLookUp("[total]","myquery","[topic] = 3") How can I pass a value from a field on my report to a query so I can return the query's single numeric value? Thanks.

  • Java - How to pass a Generic parameter as Class<T> to a constructor

    - by Joe Almore
    I have a problem here that still cannot solve, the thing is I have this abstract class: public abstract class AbstractBean<T> { private Class<T> entityClass; public AbstractBean(Class<T> entityClass) { this.entityClass = entityClass; }... Now I have another class that inherits this abstract: @Stateless @LocalBean public class BasicUserBean<T extends BasicUser> extends AbstractBean<T> { private Class<T> user; public BasicUserBean() { super(user); // Error: cannot reference user before supertype contructor has been called. } My question is how can I make this to work?, I am trying to make the class BasicUserBean inheritable, so if I have class PersonBean which inherits BasicUserBean then I could set in the Generic the entity Person which also inherits the entity BasicUser. And it will end up being: @Stateless @LocalBean public class PersonBean extends BasicUserBean<Person> { public PersonBean() { super(Person.class); } ... I just want to inherit the basic functionality from BasicUserBean to all descendants, so I do not have to repeat the same code among all descendants. Thanks!.

  • Accessing both stored procedure output parameters AND the result set in Entity Framework?

    - by MS.
    Is there any way of accessing both a result set and output parameters from a stored procedure added in as a function import in an Entity Framework model? I am finding that if I set the return type to "None" such that the designer generated code ends up calling base.ExecuteFunction(...) that I can access the output parameters fine after calling the function (but of course not the result set). Conversely if I set the return type in the designer to a collection of complex types then the designer generated code calls base.ExecuteFunction<T>(...) and the result set is returned as ObjectResult<T> but then the value property for the ObjectParameter instances is NULL rather than containing the proper value that I can see being passed back in Profiler. I speculate the second method is perhaps calling a DataReader and not closing it. Is this a known issue? Any work arounds or alternative approaches? Edit My code currently looks like public IEnumerable<FooBar> GetFooBars( int? param1, string param2, DateTime from, DateTime to, out DateTime? createdDate, out DateTime? deletedDate) { var createdDateParam = new ObjectParameter("CreatedDate", typeof(DateTime)); var deletedDateParam = new ObjectParameter("DeletedDate", typeof(DateTime)); var fooBars = MyContext.GetFooBars(param1, param2, from, to, createdDateParam, deletedDateParam); createdDate = (DateTime?)(createdDateParam.Value == DBNull.Value ? null : createdDateParam.Value); deletedDate = (DateTime?)(deletedDateParam.Value == DBNull.Value ? null : deletedDateParam.Value); return fooBars; }

  • Passing values for method

    - by Kasun
    I beginner for programming. So can you please show me how to pass values for your compile() method. class CL { private const string clexe = @"cl.exe"; private const string exe = "Test.exe", file = "test.cpp"; private string args; public CL(String[] args) { this.args = String.Join(" ", args); this.args += (args.Length > 0 ? " " : "") + "/Fe" + exe + " " + file; } public Boolean Compile(String content, ref string errors) { //remove any old copies if (File.Exists(exe)) File.Delete(exe); if (File.Exists(file)) File.Delete(file); File.WriteAllText(file, content); Process proc = new Process(); proc.StartInfo.UseShellExecute = false; proc.StartInfo.RedirectStandardOutput = true; proc.StartInfo.RedirectStandardError = true; proc.StartInfo.FileName = clexe; proc.StartInfo.Arguments = this.args; proc.StartInfo.CreateNoWindow = true; proc.Start(); //errors += proc.StandardError.ReadToEnd(); errors += proc.StandardOutput.ReadToEnd(); proc.WaitForExit(); bool success = File.Exists(exe); return success; } }

  • Generic Func<> as parameter to base method

    - by WestDiscGolf
    I might be losing the plot, but I hope someone can point me in the right direction. What am I trying to do? I'm trying to write some base methods which take Func< and Action so that these methods handle all of the exception handling etc. so its not repeated all over the place but allow the derived classes to specify what actions it wants to execute. So far this is the base class. public abstract class ServiceBase<T> { protected T Settings { get; set; } protected ServiceBase(T setting) { Settings = setting; } public void ExecAction(Action action) { try { action(); } catch (Exception exception) { throw new Exception(exception.Message); } } public TResult ExecFunc<T1, T2, T3, TResult>(Func<T1, T2, T3, TResult> function) { try { /* what goes here?! */ } catch (Exception exception) { throw new Exception(exception.Message); } } } I want to execute an Action in the following way in the derived class (this seems to work): public void Delete(string application, string key) { ExecAction(() => Settings.Delete(application, key)); } And I want to execute a Func in a similar way in the derived class but for the life of me I can't seem to workout what to put in the base class. I want to be able to call it in the following way (if possible): public object Get(string application, string key, int? expiration) { return ExecFunc(() => Settings.Get(application, key, expiration)); } Am I thinking too crazy or is this possible? Thanks in advance for all the help.

  • Passing function-specific variables

    - by Simon Carlson
    Say I got two functions that looks like this: function main(Index) { doStuff(); } function doStuff() { if(Index == 1) { document.write("Hello world!") } } And some HTML: <input type="button" value="Click me" onclick="main(1)" /> I realize this is a very stupid way to use function-specific variables and such, but it's just out of curiosity. So is it possible to pass the variable Index from the main function to the doStuff function?

  • Passing arguments to a python service

    - by Grim
    Hi, I need some help with a python service. I have a service written in Python. What I need to do is to pass it some arguments. Let me give you an example to explain it a bit better. Lets say I have a service, that does nothing but writes something to a log. I'd like to write the same thing into the log several times, so I use a loop. I would like to pass the counter for the loop when I start the service, but I have no idea how. I start the service with: win32serviceutil.HandleCommandLine(WinService) I'm looking for something like win32serviceutil.HandleCommandLine(WinService,10) I don't really care how its done, as long as I can pass arguments to it. Have been trying to get this to work for the better part of the day with no luck. Also, the service isn't run directly, but is imported and then run from there.

  • Passing URIs as URL arguments in Drupal 6

    - by wynz
    I'm running into problems trying to pass absolute URIs as parameters with clean URLs enabled. I've got hook_menu() set up like this: function mymodule_menu() { return array( 'page/%' = array( 'title' = 'DBpedia Display Test', 'page callback' = 'mymodule_dbpedia_display', 'page arguments' = array(1), ), ); } and in the page callback: function mymodule_dbpedia_display($uri) { // Make an HTTP request for this URI // and then render some things return $output; } What I'm hoping to do is somehow pass full URIs (e.g. "http://dbpedia.org/resource/Coffee") to my page callback. I've tried a few things and nothing's worked so far... http://mysite.com/page/http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Completely breaks Drupal's rewriting http://mysite.com/page/?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Gives a 404 http://mysite.com/page/http://dbpedia.org/resource/Coffee Returns just "http:", which makes sense I could probably use $_GET to pull out the whole query string, but I guess I'm hoping for a more 'Drupal' solution. Any suggestions?

  • Making fscanf Ignore Optional Parameter

    - by adi92
    I am using fscanf to read a file which has lines like Number <-whitespace- string <-whitespace- optional_3rd_column I wish to extract the number and string out of each column, but ignore the 3rd_column if it exists Example Data: 12 foo something 03 bar 24 something #randomcomment I would want to extract 12,foo; 03,bar; 24, something while ignoring "something" and "#randomcomment" I currently have something like while(scanf("%d %s %*s",&num,&word)>=2) { assign stuff } However this does not work with lines with no 3rd column. How can I make it ignore everything after the 2nd string?

  • Passing derived objects in a constructure

    - by Clarence Klopfstein
    This is a bit of a convoluted question, hopefully I can make it clear. I am finding that this may not be possible, but am trying to see if anybody has a solution. I have four classes, two are core classes and two are those core classes extended: extUser Extends coreUser extSecurity Extends coreSecurity In the constructor for coreUser you have this: public coreUser(string id, ref coreSecurity cs) When trying to extend coreUser you would have this: public extUser(string id ref extSecurity es) : base(id, ref es) This fails because es is of type, extSecurity and the base class expects a type of coreSecurity. I've not found anyway to cast this to allow for me to override this base class in C#. In VB it works just fine. Ideas?

  • C++ passing arguments to a program already running

    - by wyatt
    I'm reading through a tutorial on using voice commands to control applications and, in an example of controlling rhythmbox, it suggests commands such as the following can be executed: rhythmbox-client --play rhythmbox-client --pause Why does this not simply open a new instance of the program, and how can I emulate the functionality in my own programs? For example, how could I pass a string to a particular instance of a program? Thanks

  • Calling C++/CLI Method with System::DateTime parameter requires 'ValueType' as a parameter?

    - by David Ipsen
    I'm attempting to call a method written in C++/CLI from C#. The C++/CLI code is used to update a TIMESTAMP column in an Oracle database, given a record ID and the System::DateTime object which is the .NET compatible data type for Oracle's TIMESTAMP type. The method I am calling has the following prototype: bool ChangeJobUpdateDate (int jobIdIn, System::DateTime^ updateDateIn) I've added a reference to this DLL project in a test project that I made; I'm writing the tests in C#. However, when I try to call this method from the C# unit test project, the function appears to have the following method declaration (via intellisense): bool ChangeJobUpdateDate (int jobIdIn, ValueType updateDateIn) I'm admittedly not that familiar with C++/CLI, so is there something I'm missing?

  • Passing NULL values into mysql Stored procedure

    - by McNabbToSkins
    I am trying to pass a few NULL values to a stroed procedure but PHP always retains the varaibles to be empty strings '' and not NULL. My DB insert function looks like this. (I am using a Framework and ADODB so if it looks weird thats why). function insert_emp($f_name, $last_name, $dob) { if(!isset($dob)){ $dob = NULL; } $this->DB->setConnection("CALL insert_emp('$f_name', '$l_name', '$dob')"); } I have ensured that $dob is being passed an empty string ''. But for some reason when it calls the stored proc it is not changed to NULL. dob is a datetime field and mysql complains that you can not enter an empty string as a DATETIME. If I hard code the insert such as this $this->DB->setConnection("CALL insert_emp('Test1', 'Test2', 'NULL')"); it will work. Thanks for the help.

  • pass parameter from controller to models condition

    - by Alex
    I'm trying to bind a param to a join via a named scope., but I'm getting an error. What is the correct way to do that? has_one :has_voted, :class_name => 'Vote', :conditions => ['ip = :userIp'] # named scopes scope :with_vote, lambda {|ip| { :include => [:has_voted], # like this ?? :conditions => [:has_voted => {:conditions => {:userIp => ip}} ] }} Idea.with_vote(request.ip).all I believe I need the condition definition in the model for it to appear in the ON clause of a JOIN, rather then in the WHERE one. Edit I'm trying to get the following query select Ideas.*, Votes.* from Ideas left outer join Votes on Votes.Idea_id = Idea.id AND Votes.ip = {request.ip}
