  • passing the parent form on the onclick event to javascript function

    - by user1051505
    Hi I am trying to pass variables on the onclick event to a javascript function. I am trying the following way, I can't get the input value in the javascript function.(I am expecting an alert of 1.) Is it the right way of doing this? Please help. <head> <script> function submit_value(form) { alert(form.ip.value); } </script> </head> <table> <tr> <form> <td> <input id="ip" type="text" value="1"> </td> <td> <a href="javascript:;" onClick="submit_value(this)">Button</a> </td> </form> </tr> </table>

  • .htaccess & mod_rewrite for passing GET parameters

    - by Joel Alejandro
    Currently I use this to pass GET parameters on an "elegant" way: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^([^/]*)/$ index.php?module=$1 [L] RewriteRule ^([^/]*)/([^/]*)/$ index.php?module=$1&object=$2 [L] RewriteRule ^([^/]*)/([^/]*)/([^/]*)/$ index.php?module=$1&object=$2&submodule=$3 [L] This works great for 3 parameters max., (and I'm sure it's seriously ugly). Any way to do the same thing, for n-paremeters?

  • Passing System classes as constructor parameters

    - by mcl
    This is probably crazy. I want to take the idea of Dependency Injection to extremes. I have isolated all System.IO-related behavior into a single class so that I can mock that class in my other classes and thereby relieve my larger suite of unit tests of the burden of worrying about the actual file system. But the File IO class I end up with can only be tested with integration tests, which-- of course-- introduces complexity I don't really want to deal with when all I really want to do is make sure my FileIO class calls the correct System.IO stuff. I don't need to integration test System.IO. My FileIO class is doing more than simply wrapping System.IO functions, every now and then it does contain some logic (maybe this is the problem?). So what I'd like is to be able to test my File IO class to ensure that it makes the correct system calls by mocking the System.IO classes themselves. Ideally this would be as easy as having a constructor like so: public FileIO( System.IO.Directory directory, System.IO.File file, System.IO.FileStream fileStream ) { this.Directory = directory; this.File = file; this.FileStream = fileStream; } And then calling in methods like: public GetFilesInFolder(string folderPath) { return this.Directory.GetFiles(folderPath) } But this doesn't fly since the System.IO classes in question are static classes. As far as I can tell they can neither be instantiated in this way or subclassed for the purposes of mocking.

  • How to debug iPhone project crash when there is no error message

    - by teepusink
    Hi, I am doing this iPhone app that works fine on the simulator. However, when I run it on a device in debug mode, it just crash without any error messages. How can I debug that? I heard about a flag we can set to help with this kind of situation but not sure what that flag is and how to set it. If I'm not mistaken I think what that flag does is put a break point automatically prior to crash. Thanks, Tee

  • Trouble Passing Parameter to LinqToSql Stored Procedure

    - by Webjedi
    public IEnumerable<T> ExecuteStoredProcedure<T>(params object[] parameters) { Type genericType = typeof(T); string commandthing = genericType.Name.Replace("Result", ""); //_db is my Linq To Sql database return _db.ExecuteQuery<T>(commandthing, parameters).AsEnumerable(); } The stored procedure is named GetOrder and has a single int parameter of orderid. I'm calling the above like so: SqlParameter parm1 = new SqlParameter("@orderid", SqlDbType.Int); parm1.Value = 123; var results = _session.ExecuteStoredProcedure<GetOrderResult>(parm1).Single(); I'm receiving the following error: A query parameter cannot be of type 'System.Data.SqlClient.SqlParameter' Thoughts? Or am I just missing something obvious?

  • Passing arguments and conditions to model in codeigniter

    - by stormdrain
    I'm adding some models to a project, and was wondering if there is a "best practice" kind of approach to creating models: Does it make sense to create a function for each specific query? I was starting to do this, then had the idea of creating a generic function that I could pass parameters to. e.g: Instead of function getClients(){ return $this->db->query('SELECT client_id,last FROM Names ORDER BY id DESC'); } function getClientNames($clid){ return $this->db->query('SELECT * FROM Names WHERE client_id = '.$clid); } function getClientName($nameID){ return $this->db->query('SELECT * FROM Names WHERE id ='.$nameID); } } Something like function getNameData($args,$cond){ if($cond==''){ $q=$this->db->query('SELECT '.$args.' FROM Names'); return $q; }else{ $q=$this->db->query('SELECT '.$args.' FROM Names WHERE '.$cond); return $q; } } where I can pass the fields and conditions (if applicable) to the model. Is there a reason the latter example would be a bad idea? Thanks!

  • Passing functor and function pointers interchangeably using a templated method in C++

    - by metroxylon
    I currently have a templated class, with a templated method. Works great with functors, but having trouble compiling for functions. Foo.h template <typename T> class Foo { public: // Constructor, destructor, etc... template <typename Func> void bar(T x, Func f); }; template <typename T> template <typename Func> Foo::bar(T x, Func f) { /* some code here */ } Main.cpp #include "Foo.h" template <typename T> class Functor { public: Functor() {} void operator()(T x) { /* ... */ } private: /* some attributes here */ }; void Function(T x) { /* ... */ } int main() { Foo<int> foo; foo.bar(2, Functor); // No problem foo.bar(2, Function); // <unresolved overloaded function type> return 0; }

  • passing parameters to a thread

    - by assassin
    I want to pass a function that takes a parameter to the ThreadStart Constructor in C#. But, it seems that this is not possible, as I get a syntax error it I try to do something like this Thread t1 = new Thread(new Thread Start(func1(obj1)); where obj1 is an object of type List<string> (say). If I want a thread to execute this function that takes in an object as a parameter, and I plan to create 2 such threads simultaneously with different parameter values what is the best method to achieve this?

  • Passing data to a jQuery click() function

    - by jakenoble
    Hi I have a simple span like so <span class="action removeAction">Remove</span> This span is within a table, each row has a remove span. And then I call a URL using AJAX when that span is clicked. The AJAX event needs to know the ID of the object for that row? What is the best way of getting that ID into the click function? I thought I could do something like this <span class="action removeAction" id="1">Remove</span> But an ID should not start with a number? Right? Then I thought I could do <span class="action removeAction" id="my1">Remove</span> Then just strip the 'my' part from the ID, but that just seems Yuk! Below is my click event and where my AJAX event is. <script type="text/javascript" language="text/javascript"> $(document).ready(function() { $(".removeAction").click(function() { //AJAX here that needs to know the ID } }); </script> I am sure there is a nice way of doing this? Thanks. Jake.

  • Passing around a SqlConnection

    - by Chris
    I have created a TransactionScope and within the scope various items are created and updated in the database. During this process I make a lot of calls to the database. Originally I opened a SqlConnection in the beginning of the TransactionScope and passed it around to any function that made a DB call then I closed the connection after all the calls are made and before the transaction commits. Is it better to do this or to open and close a connection for each call?

  • Java Thread Message Passing

    - by pkulak
    I'm writing an Android app. I have a main method, which creates and runs a new Thread using an anonymous inner Runnable class. The run() method, when it's done, calls a method on it's parent class (in the main thread) that calls notifyDataSetChanged() so that the main thread can redraw the new data. This is causing all kinds of trouble (ViewRoot$CalledFromWrongThreadException). The thing is, this method being called from the worker thread is on the class that's created in the UI thread. Shouldn't that be running on the UI thread? Or am I missing something? Here's some code about what I'm talking about: public class Mealfire extends Activity { @Override public void onCreate(Bundle icicle) { (new Thread() { public void run() { // Do a bunch of slow network stuff. update(); } }).start(); } private void update() { myAdapter.notifyDatasetChanged(); } }

  • Passing.getText() String to another class

    - by DanMc
    I'm currently working on a first year university project and I have a problem, although I doubt it's a very complicated one, but I've been searching and I just can't find a suitable answer to it. The problem concerns two classes. A gui class (class1) and another class (class2). I have a JTextField in class1 and am trying to pass through the .getText() value to class2 and store it in a String type variable. The current code I'm trying to achieve this with is the following: (Class1) private JTextField textField = new JTextField("Something"); ... public String getTextFieldString() { return textField.getText(); } (Class2) private c1 Class1 = new Class1(); private String s = new String(); ... s = c1.getTextFieldString(); I'm pretty new to coding, I've read that maybe I need to pass through an argument somewhere and I assume that's because textField is not static in itself, it changes when somebody enters a new value. (sorry for stating the obvious there.) Anyway, help is appreciated. Thanks a lot!

  • Passing C++ object to C++ code through Python?

    - by cornail
    Hi all, I have written some physics simulation code in C++ and parsing the input text files is a bottleneck of it. As one of the input parameters, the user has to specify a math function which will be evaluated many times at run-time. The C++ code has some pre-defined function classes for this (they are actually quite complex on the math side) and some limited parsing capability but I am not satisfied with this construction at all. What I need is that both the algorithm and the function evaluation remain speedy, so it is advantageous to keep them both as compiled code (and preferrably, the math functions as C++ function objects). However I thought of glueing the whole simulation together with Python: the user could specify the input parameters in a Python script, while also implementing storage, visualization of the results (matplotlib) and GUI, too, in Python. I know that most of the time, exposing C++ classes can be done, e.g. with SWIG but I still have a question concerning the parsing of the user defined math function in Python: Is it possible to somehow to construct a C++ function object in Python and pass it to the C++ algorithm? E.g. when I call f = WrappedCPPGaussianFunctionClass(sigma=0.5) WrappedCPPAlgorithm(f) in Python, it would return a pointer to a C++ object which would then be passed to a C++ routine requiring such a pointer, or something similar... (don't ask me about memory management in this case, though :S) The point is that no callback should be made to Python code in the algorithm. Later I would like to extend this example to also do some simple expression parsing on the Python side, such as sum or product of functions, and return some compound, parse-tree like C++ object but let's stay at the basics for now. Sorry for the long post and thx for the suggestions in advance.

  • Passing $_GET or $_POST data to PHP script that is run with wget

    - by Matt
    Hello, I have the following line of PHP code which works great: exec( 'wget http://www.mydomain.com/u1.php /dev/null &' ); u1.php acts to do various types of maintenance on my server and the above command makes it happen in the background. No problems there. But I need to pass variable data to u1.php before it's executed. I'd like to pass POST data preferably, but could accommodate GET or SESSION data if POST isn't an option. Basically the type of data being passed is user-specific and will vary depending on who is logged in to the site and triggering the above code. I've tried adding the GET data to the end of the URL and that didn't work. So how else might I be able to send the data to u1.php? POST data preferred, SESSION data would work as well (but I tried this and it didn't pick up the logged in user's session data). GET would be a last resort. Thanks!

  • Passing around objects to network packet handlers ?

    - by xeross
    Hey, I've been writing a networking server for a while now in C++ and have come to the stage to start looking for a way to properly and easily handle all packets. I am so far that I can figure out what kind of packet it is, but now I need to figure out how to get the needed data to the handler functions. I had the following in mind: Have a map of function pointers with the opcode as key and the function pointer as value Have all these functions have 2 arguments, packet and ObjectAccessor ObjectAccessor class contains various functions to fetch various items such as users and alike Perhaps pass the user's guid too so we can fetch it from the objectaccessor I'd like to know the various implementations others have come up with, so please comment on this idea and reply with your own implementations. Thanks, Xeross

  • Passing windows credentials through web application, to WCF

    - by IP
    I've checked other questions, but I can't find a working answer I have a .Net web application which successfully takes on the callers windows credentials (Thread.CurrentPrincipal is my windows user). Within that app, I call to a WCF service, but my windows identity isn't passed up. Regardless of what I put in the binding: NetTcpBinding binding = new NetTcpBinding(); binding.Security.Mode = SecurityMode.Transport; binding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows;

  • Passing an array of an array of char to a function

    - by L.A. Rabida
    In my program, I may need to load a large file, but not always. So I have defined: char** largefilecontents; string fileName="large.txt"; When I need to load the file, the program calles this function: bool isitok=LoadLargeFile(fileName,largefilecontents); And the function is: bool LoadLargeFile(string &filename, char ** &lines) { if (lines) delete [] lines; ifstream largeFile; #ifdef LINUX largeFile.open(filename.c_str()); #endif #ifdef WINDOWS largeFile.open(filename.c_str(),ios::binary); #endif if (!largeFile.is_open()) return false; lines=new char *[10000]; if (!lines) return false; largeFile.clear(); largeFile.seekg(ios::beg); for (int i=0; i>-1; i++) { string line=""; getline(largeFile,line); if (largeFile.tellg()==-1) break; //when end of file is reached, tellg returns -1 lines[i]=new char[line.length()]; lines[i]=const_cast<char*>(line.c_str()); cout << lines[i] << endl; //debug output } return true; } When I view the debug output of this function, "cout << lines[i] << endl;", it is fine. But when I then check this in the main program like this, it is all messed up: for (i=0; i<10000; i++) cout << largefilecontents[i] << endl; So within the function LoadLargeFile(), the results are fine, but without LoadLargeFile(), the results are all messed up. My guess is that the char ** &lines part of the function isn't right, but I do not know what this should be. Could someone help me? Thank you in advance!

  • Sharepoint Document Upload Page - Passing URL Variables?

    - by Corey O.
    Throughout my SharePoint site, I have several document repositories that are tied to primary keys from an external database. I have added custom columns in the document library metadata fields so that we will know which SharePoint documents correspond with which table entries. As a requirement, we need to have document uploads that have these fields automatically populated. For instance, I'd like to have the following url: ./Upload.aspx?ClassID=2&SystemID=63 So that when you upload any documents to this library, it automatically adds the ClassID and SystemID values to the corresponding ClassID and SystemID columns outlined in the SharePoint document library fields. Is there any quick or easy way to do this, or will I have to completely rewrite the Upload.aspx script from scratch?

  • Grid View Button Passing Data Via On Click

    - by flyersun
    Hi, I'm pretty new to C# and asp.net so aplogies if this is a really stupid question. I'm using a grid view to display a number of records from a database. Each row has an Edit Button. When the button is clicked I want an ID to be passed back to a funtion in my .cs file. How do I bind the rowID to the Button field? I've tired using a hyper link instead but this doens't seem to work because I'm posting back to the same page which already has a Permanter on the URL. asp.net <asp:GridView ID="gvAddresses" runat="server" onrowcommand="Edit_Row"> <Columns> <asp:ButtonField runat="server" ButtonType="Button" Text="Edit"> </Columns> </asp:GridView> c# int ImplantID = Convert.ToInt32(Request.QueryString["ImplantID"]); Session.Add("ImplantID", ImplantID); List<GetImplantDetails> DataObject = ImplantDetails(ImplantID); System.Data.DataSet DSImplant = new DataSet(); System.Data.DataTable DTImplant = new DataTable("Implant"); DSImplant.Tables.Add(DTImplant); DataColumn ColPostCode = new DataColumn(); ColPostCode.ColumnName = "PostCode"; ColPostCode.DataType = typeof(string); DTImplant.Columns.Add(ColPostCode); DataColumn ColConsigneeName = new DataColumn(); ColConsigneeName.ColumnName = "Consignee Name"; ColConsigneeName.DataType = typeof(string); DTImplant.Columns.Add(ColConsigneeName); DataColumn ColIsPrimaryAddress = new DataColumn(); ColIsPrimaryAddress.ColumnName = "Primary"; ColIsPrimaryAddress.DataType = typeof(int); DTImplant.Columns.Add(ColIsPrimaryAddress); DataColumn ColImplantCustomerDetailsID = new DataColumn(); ColImplantCustomerDetailsID.ColumnName = "Implant ID"; ColImplantCustomerDetailsID.DataType = typeof(int); DTImplant.Columns.Add(ColImplantCustomerDetailsID); foreach (GetImplantDetails Object in DataObject) { DataRow DRImplant = DTImplant.NewRow(); DRImplant["PostCode"] = Object.GetPostCode(); DRImplant["Consignee Name"] = Object.GetConsigneeName(); DRImplant["Primary"] = Object.GetIsPrimaryAddress(); DRImplant["Implant ID"] = Object.GeTImplantCustomerDetailsID(); DTImplant.Rows.Add(DRImplant); <--- this is what I need to be added to the button } gvAddresses.DataSource = DTImplant; gvAddresses.DataBind();

  • Passing additional data value to strongly typed partial views in ASP.NET MVC

    - by fearofawhackplanet
    I have an OrderForm domain class, which has property subclasses, something like: interface IOrderForm { int OrderId { get; } ICustomerDetails CustomerDetails { get; set; } IDeliveryDetails DeliveryDetails{ get; set; } IPaymentsDetails PaymentsDetails { get; set; } IOrderDetails OrderDetails { get; set; } } My "Details" view is strongly typed inheriting from IOrderForm. I then have a strongly type partial for rendering each section: <div id="CustomerDetails"> <% Html.RenderPartial("CustomerDetails", Model.CustomerDetails); %> </div> <div id="DeliveryDetails"> <% Html.RenderPartial("DeliveryDetails", Model.DeliveryDetails); %> </div> ... etc This works ok up to this point, but I'm trying to add some nice ajax bits for updating some parts of the order form, and I've realised that each of my partial views also needs access to the IOrderForm.OrderId. Whats the easiest way to give my partials access to this value?
