• What is the ISO C++ way to directly define a conversion function to reference to array?

  - by ben

  According to the standard, a conversion function has a function-id operator conversion-type-id, which would look like, say, operator char(&)[4] I believe. But I cannot figure out where to put the function parameter list. gcc does not accept either of operator char(&())[4] or operator char(&)[4]() or anything I can think of. Now, gcc seems to accept (&operator char ())[4] but clang does not, and I am inclined to not either, since it does not seem to fit the grammar as I understand it. I do not want to use a typedef because I want to avoid polluting the namespace with it.

• How do I pass a multi-dimensional array as a GET parameter in PHP?

  - by Onema

  I have the following code. $connect = new Connection (); $response = $connect->putFile($fileName, $destination); header("Location: /test.php?response=" . $response); When I invoke header with the response, the file will stop execution, but I will have no error in the console... I am thinking maybe this array needs to be encoded for the url? if that is the case how? Thank you

• Is it possible to set a parameterized build or pass an environment variable via a hudson build trigger?

  - by Tim

  I'd like to use hudson to trigger a "promotion" of a build. The build would be a simple script that just copies a release candidate installer file from one location to another. (development dir to release/stable dir) Our build server is not on the public internet, but I want to be able to send an email or a text message or an IM with the build number to hudson, which will parse the build number and then do the copy/move. In looking at the jabber/IM plugin it does not look like this is possible (the parameter part) Has anyone solved this in some way? Should I use some other mechanism? I would prefer not to have to do the manual steps each time (SCP/FTP, etc) - I just want any QA team member to be able to trigger the build server to do the promotion.

• How to pass a class method as an argument for another function in C++ and openGL?

  - by tsubasa

  I know this thing works: void myDisplay() { ... } int main() { ... glutDisplayFunc(myDisplay) ... } so I tried to include myDisplay() function to a class that I made. Because I want to overload it in the future with a different class. However, the compiler complains that argument of type 'void (ClassBlah::)()' does not match 'void(*)()' . Here is the what I try to make: class ClassBlah { .... void myDisplay() .... } ...... int main() { ... ClassBlah blah glutDisplayFunc(blah.myDisplay) ... } Does anybody knows how to fix this problem? Many thanks.

• Can I pass a string variable into an <a href> tag for a website link?

  - by Joseph

  I am somewhat new to web developing, so I am trying to learn along the way. I have a div that is 500 x 500. Inside of that div I have two divs that are each 250x500. So my outer div is filled up with the two inner divs. I have it setup so that when I click on the first div (the left one) a java script is called, and a prompt pop up box asks for a website URL which is then stored inside of a string variable. How can I make it so that the second div (the right one) takes the string variable from the alert box from the left div and puts it into an a href tag so that I can link to the website from the right div? Can a a href tag accept a value from a variable for its link? Maybe I am going about this all wrong, is there a better way I should be approaching this? Any help is appreciated!!

• How to reference a string from another package in a library using XML in Android?

  - by Garret Wilson

  The Android documentation tells me that I can access a string from another package by using the "package name", whatever that means: @[<package_name>:]<resource_type>/<resource_name> So in my manifest I want to access a string that I've placed in a separate library project, in the com.globalmentor.android package---that's where my R class is, after all: <activity android:label="@com.globalmentor.android:string/app_applicationlistactivity_label" android:name="com.globalmentor.android.app.ApplicationListActivity" > </activity> That doesn't even compile. But this does: <activity android:label="@string/app_applicationlistactivity_label" android:name="com.globalmentor.android.app.ApplicationListActivity" > </activity> Why? What does the Android documentation mean which it talks about the "package_name"? Why doesn't the first example work, and why does the second example work? I don't want all my resource names merged into the same R file---I want them partitioned into packages, like I wrote them.

• When I try to pass large amounts of information using jquery $.ajax(post) method. it throws potenti

  - by dotnetrocks

  I am trying to create a preview window for my texteditor in my blog page. I need to send the content to the server to clean up the text entered before I can preview it on the preview window. I was trying to use $.ajax({ type: method, url: url, data: values, success: LoadPageCallback(targetID), error: function(msg) { $('#' + targetID).attr('innerHTML', 'An error has occurred. Please try again.'); } }); Whenever I tried to click on the preview button it returns an XMLHTTPRequest error. The error description - Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. The ValidateRequest for the page is set to false. Is there a way I can set validaterequest to false for the ajax call.Please advise Thank you for reading my post.

• Can I get a reference to an object created in a jQuery plugin?

  - by gargantaun

  Perhaps my brain is fried, but I'm writing a plugin that created an tweaks an element, but also creates an object that i'd like access to. So the plugin looks like this (function ($) { $.fn.myPlugin = function () { return this.each(function () { // do some stuff to the element... this.objectInstance = new usefulObject(); }); }; })(jQuery); function usefulObject(){ // useful object properties and methods.... this.doSomething = function(){ alert("Don't google Google. You'll break the internet."); } } so when I call the plugin, I also want to be able to get access to that usefulObject that I created. I thought something like this might work.... tweakedElement = $("#someDiv").myPlugin(); tweakedElement.objectInstance.doSomething(); ... but that's not working. How can I achieve this? Can I achieve this? Answers on a postcard, or down below, whichever suits you.

• How do I pass dependency to object with Castle Windsor and MS Test?

  - by Nick

  I am trying to use Castle Windsor with MS Test. The test class only seems to use the default constructor. How do I configure Castle to resolve the service in the constructor? Here is the Test Class' constructors: private readonly IWebBrowser _browser; public DepressionSummaryTests() { } public DepressionSummaryTests(IWebBrowser browser) { _browser = browser; } My component in the app config looks like so: <castle> <components> <component id="browser" service="ConversationSummary.IWebBrowser, ConversationSummary" type="ConversationSummary.Browser" /> </components> </castle> Here is my application container: public class ApplicationContainer : WindsorContainer { private static IWindsorContainer container; static ApplicationContainer() { container = new WindsorContainer(new XmlInterpreter(new ConfigResource("castle"))); } private static IWindsorContainer Container { get { return container; } } public static IWebBrowser Browser { get { return (IWebBrowser) Container.Resolve("browser"); } } } MS test requires the default constructor. What am I missing? Thanks!

• Pass object from JSON into MVC Controller - its always null ?

  - by SteveCl

  Hi I have seen a few questions on here related to the a similar issue, I have read them, followed them, but still i have the same problem. I am basically creating an object in javascript and trying to call a method on the controller that will return a string of html. Not JSON. I've been playing around with dataType and contentType but still no joy. So apologies if the code snippets are a bit messy. Build the object in JS. function GetCardModel() { var card = {}; card.CardTitle = $("#CardTitle").val(); card.TopicTitle = $("#TopicTitle").val(); card.TopicBody = $("#TopicBody").data("tEditor").value(); card.CardClose = $("#CardClose").val(); card.CardFromName = $("#CardFromName").val(); return card; } Take a look at the object - all looks good and as it should in JSON. var model = GetCardModel(); alert(JSON.stringify(GetCardModel())); Make the call... $.ajax({ type: "POST", url: "/Postcard/Create/Preview/", dataType: "json", //contentType: "application/json", date: GetCardModel(), processData: true, success: function (data) { alert("im back"); alert(data); }, error: function (xhr, ajaxOptions, error) { alert(xhr.status); alert("Error: " + xhr.responseText); //alert(error); } }); Always when I step into the controller, the object is ALWAYS there, but with null values for all the properties.

• Where can I find "reference barcodes" to verify barcode library output?

  - by mjustin

  This question is not about 'best' barcode library recommendation, we use various products on different platforms, and need a simple way to verify if a given barcode is correct (according to its specification). There are some free online bar code generators in the Internet, and I found many differences between their output and our library output regarding graphics and text field below the code. Now I am not sure which one is wrong, and before filing bug report I want to make sure how the correct barcode should look like. We mainly need Code128 and UCC/EAN-128 with A/B/C subcodes. Which resource would you suggest?

• Is it possible to reference a file stored in Isolated Storage by its URI?

  - by Joel

  Using this previous question as motivation, I would like to temporarily store images and videos in Isolated Storage. My application (written in WPF/C#) will allow a user to review these temporarily stored items by viewing their contents in a MediaElement. I was hoping to set the MediaElement's Source Property to a video or image's URI stored in IsolatedStorage but I cannot figure out how to dynamically create a URI since it doesn't appear to be naively supported by IsolatedStorage. Any help would be greatly appreciated - thank you in advance! Update - 1/21/09 After battling the issue for a day, I concluded that the Isolated Storage approach is not practical for storing large video files that need to be referenced by a Uri.

• Cannot pass a input from text box to a query string and then keep the string in this box.

  - by Nikita Barsukov

  I have a simple ASP.net page: <form id="form1" runat="server"> <p><asp:TextBox id="input_box" runat="server"></asp:TextBox> <asp:Button Text="OK" runat="server" OnClick="run" /></p> </form> I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads. That's the code behind page: protected void Page_Load(object sender, EventArgs e) { input_box.Text = Request.QueryString["input"]; } protected void run(object sender, EventArgs e) { string url = string.Format("?input={0}", input_box.Text); Response.Redirect(Request.Url.AbsolutePath + url); } Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?

• Couldn't I just pass an copied string to an Core Data property?

  - by dontWatchMyProfile

  The docs say: The default implementation does not copy attribute values. If the attribute value may be mutable and implements the NSCopying protocol (as is the case with NSString, for example), you can copy the value in a custom accessor to help preserve encapsulation (for example, in the case where an instance of NSMutableString is passed as a value). So instead of getting into trouble and inconvenience with overwriting accessors in my NSManagedObject subclass, couldn't I simply do something like this? myManagedObject.firstName = [[firstNameMutableStr copy] autorelease]; This would have the exact same effect, or not? The dynamic implementation would retain that anyways ... so.... why not the easy way?
