  • if else-if making code look ugly any cleaner solution?

    - by Vishal
    I have around 20 functions (is_func1, is_fucn2, is_func3...) returning boolean I assume there is only one function which returns true and I want that! I am doing: if is_func1(param1, param2): # I pass 1 to following abc(1) # I pass 1 some_list.append(1) elif is_func2(param1, param2): # I pass 2 to following abc(2) # I pass 1 some_list.append(2) ... . . elif is_func20(param1, param2): ... Please note: param1 and param2 are different for each, abc and some_list take parameters depending on the function. The code looks big and there is repetition in calling abc and some_list, I can pull this login in a function! but is there any other cleaner solution? I can think of putting functions in a data structure and loop to call them.

  • MySQL, PHP, and Apache errors while connecting to DB

    - by cypherdelton
    I'm having two errors when I test the "mysql_connect()" function in php. I just installed PHP and MySQL from scratch. These errors may be related, so I will post them both here: Warning: mysql_connect() [function.mysql-connect]: Headers and client library minor version mismatch. Headers:50158 Library:50518 in /usr/local/apache2/htdocs/index.php on line 6 Warning: mysql_connect() [function.mysql-connect]: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in /usr/local/apache2/htdocs/index.php on line 6 Many websites say to start the mysql server if you are getting error #2. Whenever I execute the command mysqld start --user=mysql I get the error "mysqld: Too many arguments (first extra is 'start'); Adding the "&" to the end of the command makes no difference (I don't know if it is supposed to). Thanks, Cypher Delton

  • Too many local variables in ASP.NET

    - by Yongwei Xing
    Hi all I wrote a control, and use a tool to do the code analysis. There is a test that I didn't pass. Avoid excessive locals, http://msdn.microsoft.com/library/ms182263(VS.90).aspx. In my CreateChildControls function, I built a big table with lots of field. I need to create a lot of TableRow and TableCell to construct the table. But these are not field or property of control. Thery are local variables in the function, which are created dynamically. Should I make these TableCells and TableRows as fields of the control? Or I just keep them as the local variables in the CreateChildControl function? Best Regards,

  • Problem TreeView OnTreeNodePopulate event

    - by purnang.advant
    Hi. I am using a treeview in asp.net 3.5(using c#.net),which is populated from sqldatabase. OnTreeNodePopulate event fires this event, protected void tvLabs_TreeNodePopulate(object sender, System.Web.UI.WebControls.TreeNodeEventArgs e) { PopulateSubLevelLab(e.Node.Value, e.Node); //This function is used for populating the child node. FillLabGrid(e.Node.Value);---My Question? } ---My Question? The FillLabGrid method used for fill a grid view on the basis of selecting the treeview parent node. But this function filled the grid only once when i click the parent node for the first time. Secondly when i collapse the treeview and again click on the parent node function (tvLabs_TreeNodePopulate)is not called? Hope you are getting my point. Please advice me. Thanks in advance.

  • Full automatic application trace for .net v4

    - by JL
    I would like to implement a way to trace every line of code in an application that is written for .net v4.0. An example would be. If I had the following function. private bool hasValue(string value) { if(string.isnullorempty(value) { return false; } else { return true; }} Then when the function is called I want detailed trace logs to contain something like this: Function called |Line 10 |Signature private bool hasValue(string value)|ValuesPassed hasValue("") Line Evaluated | Line 11 | if(string.isnullorempty(value) |ValuesPassed if(string.isnullorempty("") - evaluation returned true entered line 13 |signature return false|return action taken. This tracing can be done manually, but its a lot of work, and would dirty the code. Isn't there a way to get this level of tracing automatically with .net or 3rd party plugin? Thank you

  • object consisting of jQuery element

    - by Adam Kiss
    hello, current code I've built function to do something over collection of jQuery elements: var collection = $([]); //empty collection I add them with: collection = collection.add(e); and remove with: collection = collection.not(e); It's pretty straightforward solution, works nicely. problem Now, I would like to have an object consisting of various settings set to any jQuery element, i.e.: function addObject(e){ var o = { alpha: .6 //float base: {r: 255, g: 255, b: 255} //color object } e.data('settings', o); } But when I pass jQuery object/element to function (i.e. as e), calling e.data doesn't work, although it would be simplest and really nice solution. question If I have an "collection" of jQuery elements, what is the simplest way of storing some data for each element of set?

  • Paging with jQuery

    - by zurna
    I get data from another page using jQuery get method. But I have a small problem. Sometimes, data that I take from another page is too long so it's divided into pages. When the user clicks on 1, 2, 3, ... links he/she is redirected to the other page. However, I want data to be reloaded on the same page. Edit $('ul.thumbs li.pagination a').live('click', function() { var pageNumber = parseInt($(this).text().replace(/[^0-9]/g, '')); $.ajax({ type: "GET", url: "images.cs.asp?Process=ViewImages&PAGEID=<%=Request.QueryString("PAGEID")%>", success: function(data) { $("#ViewImages").html(data); }, error: function (XMLHttpRequest, textStatus, errorThrown) { $("#ViewImages").html('.'); } }); return false; });

  • allow waiting user experience while file upload with rails and jquery

    - by poseid
    I am trying to display a waiting spinnger, while uploading a file. I am able to show the spinner, and to do the upload, when doing it individually. My problem is how to combine these two. The Jquery Javascript looks like: <% javascript_tag do %> function showLoading() { $("#loading").show(); } function hideLoading() { $("#loading").hide(); } function submitCallback() { showLoading(); $.post("create"); } <% end % My form looks like: <% semantic_form_for @face, :html => {:multipart => true} do |f| %> <%= f.error_messages %> <%= render 'fields', :f => f %> <p> <%= button_to_function 'create', "submitCallback()" %> </p> <% end %>

  • Force result for empty() test on an object

    - by hsz
    Hello ! Simple class for example: class Foo { protected $_bar; public function setBar( $value ) { $this->_bar = $value; } } And here is the question: $obj = new Foo(); var_dump( empty( $obj ) ); // true $obj->setBar( 'foobar' ); var_dump( empty( $obj ) ); // false Is it possible to change class's behaviour with testing it with empty() function so it will returns true when object is not filled with data ? I know about magic function __isset( $name ) but it is called only when we test specific field like: empty( $obj->someField ); but not when test whole object.

  • How to change the value of progressbar in C#?

    - by shekhar
    Hi, I want to add an progress bar into my C# based application. I would like to know what is the good way of updating its value at particular events? My problem is, I have single function in UI which does all the processing.This function in turn calls many more functions, creates objects, updates database, etc. (basically performs all the work) and returns values in an output file. I have access to that function only. So in this how to update the progressbar's value at the end of each step? What is the best practice for this kind of situation? What is the good way to keep UI logic and business logic seperate? I want to avoid writting progressbar related code in my library code. Please suggest some solution. Thanks and Regards,

  • How to do a for loop in windows command line?

    - by TheFoxx
    I was wondering if this was possible? I'm not familiar with using windows command line, but I have to use it for a project I'm working on. I have a a number of files, for which I need to perform a function for each. I'm used to working with python, but obviously this is a bit different, so I was hoping for some help. Basically I need the for loop to iterate through 17 files in a folder, perform a function on each (that's using the specific software I have here for the project) and then that will output a file with a unique name (the function normally requires me to state the output file name) I would suck it up and just do it by hand for each of the 17, but basically it's creating a database of a file, and then comparing it to each of the 17. It needs to be iterated through several hundred times though. Using a for loop could save me days of work. Suggestions?

  • One click handler for multiple elements?

    - by user246114
    Hi, I'm looking to add a click handler to a div. But is there a way to use a single click handler function and share it between multiple divs? Since I may have 100 divs, I don't want to create a click handler for each (they'll all practically do the same thing). The jquery example shows: $("p").click(function () { $(this).foo(); }); can we do something like: $("p").click(myClickHandler); function myClickHandler(source) { source.foo(); } ? Thanks

  • jQuery display problem?

    - by SLAPme
    How do I hide the #changes-saved code using jQuery? For example let's say the code is displayed when the user clicks the submit button and then leaves the current web page and then returns back to the web page and the #changes-saved is no longer displayed until the submit button is clicked again. Here is the jQuery code. $(function() { $('#changes-saved').hide(); $(".save-button").click(function() { $.post($("#contact-form").attr("action"), $("#contact-form").serialize(), function(html) { $("div.contact-info-form").html(html); $('#changes-saved').append('<li>Changes saved!</li>').show().pause(1000).hide(); }); return false; // Prevent normal submit. }); });

    Hi! I toyed around with .load() and .ajax(), but i didn't get to an end. Here's what I need: Everey minute the function shall check if it can load a certain page. if the connection succeeds, I want the page to be refreshed, if not, nothing shall happen, the script shall retry later.

  • jquery plugin pattern using jquery.data

    - by web_dev
    I have seen this piece of code in jquery plugin patterns and the notes section mention that we could attach the plugin to the DOM element using the jQuery.data function. What I don't understand is how do I make use of this piece of code. Can somebody provide examples of how to use this functionality and explain its significance? $.fn[pluginName] = function (options) { return $Extend(this).each(function () { if (!$.data(this, 'plugin_' + pluginName)) { $.data(this, 'plugin_' + pluginName, new Plugin( this, options )); } }); };

  • Set timeout on third-party file request with jQuery

    - by markedup
    I'm trying to integrate a script file hosted by a third party into a new web site. Currently, I'm adding a SCRIPT tag to the DOM for that third-party script file on document ready: $(document).ready( function() { var extScript = document.createElement('script'); extScript.type = 'text/javascript'; extScript.src = 'http://third-party.com/scriptfile.js'; $('head').append(extScript); }); function extScriptCallback() { $('#extWidgetContainer').show(); } But sometimes that third-party script file request times out or takes a long time to respond. So, for the sake of best practice, I want to provide alternative content if the external script takes longer than e.g. 10 seconds to load. How do I achieve this? I've looked at JavaScript's native setTimeout(), as well as jQuery's delay() function, but I'm not sure which I should use--or how. Grateful for any suggestions.

    I'm using c++ Qt library and I want to do something which would do : connect(actionB11, SIGNAL(triggered()), this, SLOT(SetSomething(1, 1))); connect(actionB12, SIGNAL(triggered()), this, SLOT(SetSomething(1, 2))); connect(actionB21, SIGNAL(triggered()), this, SLOT(SetSomething(2, 1))); connect(actionB22, SIGNAL(triggered()), this, SLOT(SetSomething(2, 2))); The code above doesnt work because SIGNAL function has to have same number and argument types as SLOT function. Does exist a way how to do it? I dont want to have about 20 function as SetSomething11, SetSomething12 calling SetSomething(1, 1) etc.

  • How do C++ header files work?

    - by PulpFiction
    Hi all. When I include some function from a header file in a C++ program, does the entire header file code get copied to the final executable or only the machine code for the specific function is generated. For example, if I call std::sort from the <algorithm> header in C++, is the machine code generated only for the sort() function or for the entire <algorithm> header file. I think that a similar question exists somewhere on Stack Overflow, but I have tried my best to find it (I glanced over it once, but lost the link). If you can point me to that, it would be wonderful.

  • python dict.fromkeys() returns empty

    I wrote the following function. It returns an empty dictionary when it should not. The code works on the command line without function. However I cannot see what is wrong with the function, so I have to appeal to your collective intelligence. def enter_users_into_dict(userlist): newusr = {} newusr.fromkeys(userlist, 0) return newusr ul = ['john', 'mabel'] nd = enter_users_into_dict(ul) print nd It returns an empty dict {} where I would expect {'john': 0, 'mabel': 0}. It is probably very simply but I don't see the solution.
