  • mocking static method call to c# library class

    - by Joe
    This seems like an easy enough issue but I can't seem to find the keywords to effect my searches. I'm trying to unit test by mocking out all objects within this method call. I am able to do so to all of my own creations except for this one: public void MyFunc(MyVarClass myVar) { Image picture; ... picture = Image.FromStream(new MemoryStream(myVar.ImageStream)); ... } FromStream is a static call from the Image class (part of c#). So how can I refactor my code to mock this out because I really don't want to provide a image stream to the unit test.

  • Returning the html from .ajax call

    - by coffeeaddict
    I'm getting undefined for some reason when I try to return the html via the callback function: function getDataFromUrl(urlWithContent) { // jQuery async request $.ajax( { url: urlWithContent, dataType: "html", success: function(data) { return $('.result').html(data); }, error: function(e) { alert('Error: ' + e); } }); } I know I'm getting data back, I see it in firebug in the response and also when I alert out the data, I see the entire page content come up in the alert box. When I call my function, I am doing the following: var divContent = getDataFromUrl(dialogDiv.attr("href")); if(divContent) dialogDiv.innerHTML = divContent; when I alert out the divContent (before the if statement) I'm getting undefined. Maybe I'm just going about this wrong on how I'm returning back the data? I also tried just return data; same thing, I get undefined after the call to this method when set to my variable.

  • Confusion in bind call in socket programming

    - by Tarun
    i was learning socket programming in unix using c/c++. I am confused with one function call bind(params..). Actually it takes the adreess structure "sockaddr_in" and we can create the structure in the following way sockaddr_in.*** = somthing.. sockaddr_in..s_addr htonl(INADDR_ANY) **Passing INADDR_ANY will alow to bind all local addresses** My question is , why do we need to use "INADDR_ANY" ? In my knowledge every machine can has only one unique IP Address. In this way there is only one address associated with the machien. Thye bind call should directly bind the socket to the single available address. Please explain what are the different scenarios and why is it so?

  • Django: Set foreign key using integer?

    - by User
    Is there a way to set foreign key relationship using the integer id of a model? This would be for optimization purposes. For example, suppose I have an Employee model: class Employee(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) type = models.ForeignKey('EmployeeType') and EmployeeType(models.Model): type = models.CharField(max_length=100) I want the flexibility of having unlimited employee types, but in the deployed application there will likely be only a single type so I'm wondering if there is a way to hardcode the id and set the relationship this way. This way I can avoid a db call to get the EmployeeType object first.

  • Resolve HTTP 304 - not modified in AJAX call made via GWT

    - by Salvin Francis
    We are using an application made in GWT with the server as tomcat. The project runs fine normally, however there are situations where the server is restarted. At such point of time, the ajax call made by the code below returns blank text with the status code as 304 RequestBuilder requestBuilder = new RequestBuilder(RequestBuilder.POST, URL.encode(serverUrl)); //-- serverUrl is the url to which this call is posted to. requestBuilder.setHeader("Content-Type", "application/x-www-form-urlencoded"); requestBuilder.setHeader("Expires","0"); requestBuilder.sendRequest( postData, new RequestCallback() { public void onError(Request request, Throwable exception) { //Do nothing } public void onResponseReceived(Request request, Response response) { //sometimes when the server is restarted, I get response.getStatusCode() = 304 and the response.getText() as blank } } ); normally we get back some data from the server inside this response text. How do we now get the data when the response itself is blank ?

  • Can't call method in model table class using Doctrine with Zend Framework

    - by Jeremy Hicks
    I'm using Doctrine with Zend Framework. For my model, I'm using a base class, the regular class (which extends the base class), and a table class. In my table class, I've created a method which does a query for records with a specific value for one of the fields in my model. When I try and call this method from my controller, I get an error message saying, "Message: Unknown method Doctrine_Table::getCreditPurchases". Is there something else I need to do to call functions in my table class? Here is my code: class Model_CreditTable extends Doctrine_Table { /** * Returns an instance of this class. * * @return object Model_CreditTable */ public static function getInstance() { return Doctrine_Core::getTable('Model_Credit'); } public function getCreditPurchases($id) { $q = $this->createQuery('c') ->where('c.buyer_id = ?', $id); return $q->fetchArray(); } } // And then in my controller method I have... $this->view->credits = Doctrine_Core::getTable('Model_Credit')->getCreditPurchases($ns->id);

  • How does the dispatch action call work in the Twitter sidebar

    - by phwd
    I would like to understand how the call for replies works as follows: <a href="http://twitter.com/replies" data="{"dispatch_action":"replies"}"> <span>@phwd</span> </a> This was taken from the homepage of Twitter. The section in particular being: data="{"dispatch_action":"replies"}" I believe (think), it is using Twitter's own twitter.js script and I do not want to interfere(or copy) with their code, I rather just want to know how the call works. My current setup is using Abraham's twitteroauth PHP library, jQuery and some Ajax to refresh the portion of the page needed using the following method : Use jQuery and PHP to build an Ajax-driven Web page [IBM link - I am a new user so I can only post one link] I apologize if this question is not formatted/worded well, it is my first time. Also I tried searching DocType and StackOverFlow. The Related Questions show me Struts but I am not sure it is that.

  • Should I make my MutexLock volatile?

    - by sje397
    I have some code in a function that goes something like this: void foo() { { // scope the locker MutexLocker locker(&mutex); // do some stuff.. } bar(); } The function call bar() also locks the mutex. I am having an issue whereby the program crashes (for someone else, who has not as yet provided a stack trace or more details) unless the mutex lock inside bar is disabled. Is it possible that some optimization is messing around with the way I have scoped the locker instance, and if so, would making it volatile fix it? Is that a bad idea? Thanks.

  • Call an anonymous function defined in a setInterval

    - by Tominator
    Hi, I've made this code: window.setInterval(function(){ var a = doStuff(); var b = a + 5; }, 60000) The actual contents of the anonymous function is of course just for this small example as it doesn't matter. What really happens is a bunch of variables get created in the scope of the function itself, because I don't need/want to pollute the global space. But as you all know, the doStuff() function won't be called until 60 seconds in the page. I would also like to call the function right now, as soon as the page is loaded, and from then on every 60 seconds too. Is it somehow possible to call the function without copy/pasting the inside code to right after the setInterval() line? As I said, I don't want to pollute the global space with useless variables that aren't needed outside the function.

  • C# & C++, runtime error when call C++ dll from C#

    - by 5YrsLaterDBA
    I have written a C++ wrapper DLL for C# to call. The DLL was tested and worked fine with my C++ test program. now integrated with C#, I got runtime error and crashed. Cannot use debugger to see more details. The C++ side has only one method: #ifdef DLLWRAPPERWIN32_EXPORTS #define DLLWRAPPERWIN32_API __declspec(dllexport) #else #define DLLWRAPPERWIN32_API __declspec(dllimport) #endif #include "NB_DPSM.h" extern "C" { DLLWRAPPERWIN32_API int WriteGenbenchDataWrapper(string fileNameToAnalyze, string parameterFileName, string baseNameToSaveData, string logFileName, string& message) ; } in the C# side, there is a definition, [DllImport("..\\..\\thirdParty\\cogs\\DLLWrapperWin32.dll")] public static extern int WriteGenbenchDataWrapper(string fileNameToAnalyze, string parameterFileName, string baseNameToSaveData, string logFileName, ref string message); and a call: string msg = ""; int returnVal = WriteGenbenchDataWrapper(rawDataFileName, parameterFileName, outputBaseName, logFileName, ref msg); I guess there must be something wrong with the last parameter of the function. string& in C++ should be ref string in C#?

  • Call methods on native Javascript types without wrapping with ()

    - by Anurag
    In Javascript, we can call methods on string literals directly without enclosing it within round brackets. But not for other types such as numbers, or functions. It is a syntax error, but is there a reason as to why the Javascript lexer needs these other types to be enclosed in round brackets? For example, if we extend Number, String, and Function with an alert method and try calling this method on the literals, it's a SyntaxError for Number and Function, while it works for a String. function alertValue() { alert(this); } Number.prototype.alert = alertValue; String.prototype.alert = alertValue; Function.prototype.alert = alertValue; We can call alert directly on a string object: "someStringLiteral".alert() // alerts someStringLiteral but it's a SyntaxError on numbers, and functions. 7.alert(); function() {}.alert(); To work with these types, we have to enclose it within brackets: (7).alert(); // alerts "7" (function() {}).alert(); // alerts "function() {}"

  • Can a conforming C# compiler optimize away a local (but unused) variable if it is the only strong re

    - by stakx
    The title says it all, but let me explain: void Case_1() { var weakRef = new WeakReference(new object()); GC.Collect(); // <-- doesn't have to be an explicit call; just assume that // garbage collection would occur at this point. if (weakRef.IsAlive) ... } In this code example, I obviously have to plan for the possibility that the new'ed object is reclaimed by the garbage collector; therefore the if statement. (Note that I'm using weakRef for the sole purpose of checking if the new'ed object is still around.) void Case_2() { var unusedLocalVar = new object(); var weakRef = new WeakReference(unusedLocalVar); GC.Collect(); // <-- doesn't have to be an explicit call; just assume that // garbage collection would occur at this point. Debug.Assert(weakReferenceToUseless.IsAlive); } The main change in this code example from the previous one is that the new'ed object is strongly referenced by a local variable (unusedLocalVar). However, this variable is never used again after the weak reference (weakRef) has been created. Question: Is a conforming C# compiler allowed to optimize the first two lines of Case_2 into those of Case_1 if it sees that unusedLocalVar is only used in one place, namely as an argument to the WeakReference constructor? i.e. is there any possibility that the assertion in Case_2 could ever fail?

  • Specific template for the first element.

    I have a template: <xsl:template match="paragraph"> ... </xsl:template> I call it: <xsl:apply-templates select="paragraph"/> For the first element I need to do: <xsl:template match="paragraph[1]"> ... <xsl:apply-templates select="."/><!-- I understand that this does not work --> ... </xsl:template> How to call <xsl:apply-templates select="paragraph"/> (for the first element paragraph) from the template <xsl:template match="paragraph[1]">? So far that I have something like a loop. I solve this problem so (but I do not like it): <xsl:for-each select="paragraph"> <xsl:choose> <xsl:when test="position() = 1"> ... <xsl:apply-templates select="."/> ... </xsl:when> <xsl:otherwise> <xsl:apply-templates select="."/> </xsl:otherwise> </xsl:choose> </xsl:for-each>

  • jQuery - now: Creating an object and storing values in it to pass to an AJAX call

    - by Josh K
    I have an array: myarr = []; I'm filling it with some values: myarray['name'] = "Me!"; Now I want to transform that array into a set of Key = Value pairs. I though jQuery would do it automatically, but it doesn't seem to. $.ajax ({ type: "POST", dataType: "text", url: "myurl", data: myarr }); Is there a way to do this or something I'm doing wrong? I get no javascript errors, and no serverside errors other then no POST information at all. I need the request to be sent as a true POST request. I need to keep the php code simple because sometimes the login won't be an AJAX call. I'm now trying the following with an error unexepected token ':' myarr: { 'name':'me' } The question has now become: How do I initialize a new javascript object as "blank", how do I set up mappings, and how do I pass it in an AJAX call?

  • PHP speed optimisation.

    - by Petah
    Hi, Im wondering about speed optimization in PHP. I have a series of files that are requested every page load. On average there are 20 files. Each file must be read an parsed if they have changed. And this is excluding that standard files required for a web page (HTML, CSS, images, etc). EG - client requests page - server outputs html, css, images - server outputs dynamic content (20+/- files combined and minified). What would be the best way to serve these files as fast as possible?
