  • Page not rendering until BackgroundWorker.RunWorkerAsync completes

    - by brainimus
    I have an aspx page that on a button click creates a BackgroundWorker and then calls the RunWorkerAsync method. In my aspx file I have set Async='true' but when I run the application and click the button it appears as though the page waits to refresh until the processing of the BackgroundWorker is done. How do I get control to return to the page (and have the page refresh) after the BackgroundWorker is created and started? BackgroundWorker worker = new BackgroundWorker(); worker.DoWork += RunJob; worker.RunWorkerCompleted += JobCompleted; worker.RunWorkerAsync();

  • Login to website and use cookie to get source for another page

    - by Stu
    I am trying to login to the TV Rage website and get the source code of the My Shows page. I am successfully logging in (I have checked the response from my post request) but then when I try to perform a get request on the My Shows page, I am re-directed to the login page. This is the code I am using to login: private string LoginToTvRage() { string loginUrl = "http://www.tvrage.com/login.php"; string formParams = string.Format("login_name={0}&login_pass={1}", "xxx", "xxxx"); string cookieHeader; WebRequest req = WebRequest.Create(loginUrl); req.ContentType = "application/x-www-form-urlencoded"; req.Method = "POST"; byte[] bytes = Encoding.ASCII.GetBytes(formParams); req.ContentLength = bytes.Length; using (Stream os = req.GetRequestStream()) { os.Write(bytes, 0, bytes.Length); } WebResponse resp = req.GetResponse(); cookieHeader = resp.Headers["Set-cookie"]; String responseStream; using (StreamReader sr = new StreamReader(resp.GetResponseStream())) { responseStream = sr.ReadToEnd(); } return cookieHeader; } I then pass the cookieHeader into this method which should be getting the source of the My Shows page: private string GetSourceForMyShowsPage(string cookieHeader) { string pageSource; string getUrl = "http://www.tvrage.com/mytvrage.php?page=myshows"; WebRequest getRequest = WebRequest.Create(getUrl); getRequest.Headers.Add("Cookie", cookieHeader); WebResponse getResponse = getRequest.GetResponse(); using (StreamReader sr = new StreamReader(getResponse.GetResponseStream())) { pageSource = sr.ReadToEnd(); } return pageSource; } I have been using this previous question as a guide but I'm at a loss as to why my code isn't working.

    - by sandeep
    IS there any way so that i can convert any DOM object into HTML page within the script ? suppose I have dom object like this: content script.js chrome.extension.onRequest.addListener(function(request, sender, sendResponse) { if (request.method == "fromPopup") { console.log("got Request from Popup"); var myDivObj = document.getElementById("definition"); //sendResponse({data: "from Content Script to Popup"}); if ( myDivObj ) { sendResponse({data:myDivObj}); } else{ sendResponse({data:"Empty or No Tag"}); } console.log("sent Response1"); } else { sendResponse({}); // snub them. console.log("sent Response2"); } }); here is my popup.html <body> <Div>Searching..</Div> <Div id="output">Response??</Div> <script> console.log("Pop UP Clicked"); chrome.tabs.getSelected(null, function(tab) { chrome.tabs.sendRequest(tab.id, {method: "fromPopup", tabid: tab.id}, function(response) { console.log("got Response from Content Script"); document.getElementById("output").innerHTML=response.data; }); }); </script> </body> I know we can send onaly JSON type of data to the popup.html page.. am i right ?

  • Can we have an anonymous struct as template argument?

    - by nonoitall
    The title is pretty self-explanatory, but here's a simplified example: #include <cstdio> template <typename T> struct MyTemplate { T member; void printMemberSize() { printf("%i\n", sizeof(T)); } }; int main() { MyTemplate<struct { int a; int b; }> t; // <-- compiler doesn't like this t.printMemberSize(); return 0; } The compiler complains when I try to use an anonymous struct as a template argument. What's the best way to achieve something like this without having to have a separate, named struct definition?

  • C++ arrays as parameters, subscript vs. pointer

    - by awshepard
    Alright, I'm guessing this is an easy question, so I'll take the knocks, but I'm not finding what I need on google or SO. I'd like to create an array in one place, and populate it inside a different function. I define a function: void someFunction(double results[]) { for (int i = 0; i<100; ++i) { for (int n = 0; n<16; ++n) //note this iteration limit { results[n] += i * n; } } } That's an approximation to what my code is doing, but regardless, shouldn't be running into any overflow or out of bounds issues or anything. I generate an array: double result[16]; for(int i = 0; i<16; i++) { result[i] = -1; } then I want to pass it to someFunction someFunction(result); When I set breakpoints and step through the code, upon entering someFunction, results is set to the same address as result, and the value there is -1.000000 as expected. However, when I start iterating through the loop, results[n] doesn't seem to resolve to *(results+n) or *(results+n*sizeof(double)), it just seems to resolve to *(results). What I end up with is that instead of populating my result array, I just get one value. What am I doing wrong?

  • Load page for validation but do not display it to user in ASP.NET

    - by Kevin
    We have a site requiring users pay $2 to view the details of a record. We occasionally get complaints because we send them to the payment page, and once they pay it turns out the record isn't valid, or it was lost, or the data couldn't be generated. So we want to add in a check to ensure the page constructs properly before the user is required to pay for it. However, we don't want the user to have access to the page until they pay for it. Is there anything in ASP.NET 3.5 or just general web design that would allow something like this? The data on the record is real time and computed on a backend server before sent to the client. Occasionally this computation fails for whatever reason. Our alternative is to call all of the loading methods and validate the data, then redirect them to the payment page. The problem is A) this will be a relatively involved process rewriting all of these methods to return validation information, and B) it still doesn't guarentee us the page will load properly. Any thoughts?

  • Passing parameter to base class constructor or using instance variable?

    - by deamon
    All classes derived from a certain base class have to define an attribute called "path". In the sense of duck typing I could rely upon definition in the subclasses: class Base: pass # no "path" variable here def Sub(Base): def __init__(self): self.path = "something/" Another possiblity would be to use the base class constructor: class Base: def __init__(self, path): self.path = path def Sub(Base): def __init__(self): super().__init__("something/") What would you prefer and why? Is there a better way?

  • Trouble with Action<T1, T2> and passing multiple parameters

    - by dotnetdev
    Hi, I have this code: s(x => x.Open()); s is a method which calls one parameter, which is perfectly fine, like so: public void s(Action<p1> action) {} Ignoring the naming conventions, if I make the method like the below: public void s(Action<p1, p2> action) {} How do I pass in more than one parameter? Out of interest, is there any way to use the params keyword with Action<? Also, I am using C# 4.0 so I would be interested to see how it can help me in an way. Thanks

  • Questions on using enums as parameters and if/else conditions

    - by dotnetdev
    Hi, Is it possible to do the following with an enum in C#?: Pass in to a method a selected value of the enum (eg if an enum has members such as Red, Green, Orange, I can pass in Colors.Red). In the method body of the above method which accepts an enum, I can say if (Enum == Colors.Red). What would be the syntax for this? I've always seemed to have stalled on this.

  • Generic Constraints And Type Parameters Mess

    - by Dummy01
    Hi everyone, I have the following base abstract class defined as: public abstract class BaseObject<T> : IComparable, IComparable<T>, IEquatable<T> {} I also have an interface defined as: public interface ICode<T> where T : struct { T Code { get; } } Now I want to derive a class that is inherited from BaseObject<T> and includes interface ICode<T>. I tried to define it like that: public class DerivedObject<T, U> : BaseObject<T>, ICode<U> where T : DerivedObject<T, U> where U : struct { public DerivedObject(U code) { Code = code; } // From BaseObject protected override int InstanceCompareTo(T obj) { return Code.CompareTo(obj.Code); } // From BaseObject protected override bool InstanceEquals(T obj) { return Code.Equals(obj.Code); } // From ICode U _Code; public U Code { get { return _Code; } protected set { _Code = value; } } } The only error that comes from the compiler is for Code.CompareTo(obj.Code) with the message: 'U' does not contain a definition for 'CompareTo' and no extension method 'CompareTo' accepting a first argument of type 'U' could be found. But U is a value type and should know CompareTo. Have you any idea what I am doing wrong, or if I do all wrong? My final aim is to derive classes such these: public class Account : DerivedObject<Account, int> public class ItemGroup : DerivedObject<ItemGroup, string> Big Thanks In Advance!

  • URL Routing to Default Page

    - by ewitkows
    Hi everyone, I have an asp.net 4.0 web forms app setup with url rereouting. In development, my app's URL looks perfect. I have a page called enrollnow.aspx that responds to the routing, so if I type in localhost/enrollnow/abc, my app responds as expected. Once promoted into my staging environment however, the URL is off. I have a domain, and a virtual dir created off of my domain called "enrollnow". So basically, my URL outside of development is: mydomain.com/enrollnow/enrollnow/abc - where the first enrollnow is the directory, the second enrollnow is the page name, and the abc is my route value. Is there any way I can have the "default page" respond, so the second enrollnow (which is enrollnow.asp) isnt required? Perhaps I can rename my enrollnow.aspx page to default.aspx, or I can change the mapping in my routetable? Heres my routetable, incase that helps. thanks! Routetable: RouteTable.Routes.Add("PURLRoute", New Route("EnrollNow/{PURL_ID}", New PageRouteHandler("~/EnrollNow.aspx")))

  • Named keywords in decorators?

    - by wheaties
    I've been playing around in depth with attempting to write my own version of a memoizing decorator before I go looking at other people's code. It's more of an exercise in fun, honestly. However, in the course of playing around I've found I can't do something I want with decorators. def addValue( func, val ): def add( x ): return func( x ) + val return add @addValue( val=4 ) def computeSomething( x ): #function gets defined If I want to do that I have to do this: def addTwo( func ): return addValue( func, 2 ) @addTwo def computeSomething( x ): #function gets defined Why can't I use keyword arguments with decorators in this manner? What am I doing wrong and can you show me how I should be doing it?

  • Passing a web service an unknown number of parameters

    - by Billyhole
    I'm relatively new to utilizing web services. I'm trying to create one that will be accepting data from a ASP.Net form whose input controls are created dynamically at runtime and I don't how many control values will be getting passed. I'm thinking I'll be using jQuery's serialize() on the form to get the data, but what do I have the web service accept for a parameter? I thought maybe I could use serializeArray(), but still I don't know what type of variable to accept for the JavaScript array. Finally, I was thinking that I might need to create a simple data transfer object with the data before sending it along to the web service. I just didn't wanna go through with the DTO route if there was a much simpler way or an established best practice that I should follow. Thanks in advance for any direction you can provide and let me know I wasn't clear enough, or if you have any questions.

  • Pass arguments to a parameter class object

    - by David R
    This is undoubtedly a simple question. I used to do this before, but it's been around 10 years since I worked in C++ so I can't remember properly and I can't get a simple constructor call working. The idea is that instead of parsing the args in main, main would create an object specifically designed to parse the arguments and return them as required. So: Parameters params = new Parameters(argc, argv) then I can call things like params.getfile() Only problem is I'm getting a complier error in Visual Studio 2008 and I'm sure this is simple, but I think my mind is just too rusty. What I've got so far is really basic: In the main: #include "stdafx.h" #include "Parameters.h" int _tmain(int argc, _TCHAR* argv[]) { Parameters params = new Parameters(argc, argv); return 0; } Then in the Parameters header: #pragma once class Parameters { public: Parameters(int, _TCHAR*[]); ~Parameters(void); }; Finally in the Parameters class: include "Stdafx.h" #include "Parameters.h" Parameters::Parameters(int argc, _TCHAR* argv[]) { } Parameters::~Parameters(void) { } I would appreciate if anyone could see where my ageing mind has missed the really obvious. Thanks in advance.

  • How to prompt user input parameters for SQL Queries in Access 2010

    - by user1848907
    SELECT Transactions.TransactionNumber FROM Transactions WHERE (((Transactions.Date)>=#11/23/12#)) AND (((Transactions.Date)<=#11/23/12#)); The above code returns all the transaction that happened between the specified dates. But I want those dates to be defined by the user every time the query is executed. I tried using the [] operators to have the user define the criteria in the WHERE, something like this: WHERE (((Transactions.Date)>=[Input a Date])) AND (((Transactions.Date)<=[Input a Date])); But microsoft Access throws a Syntax error message. The same happens when I include the # (date operators) like this WHERE (((Transactions.Date)>=#[Input a Date]#)) AND (((Transactions.Date)<=#[Input a Date]#)); Is there anopther way to manage dates that I'm not aware of or is asking a user for dates in a query out of the question

  • Redirect to Apache default 404 page with mod_rewrite?

    - by Pekka
    Is there a way to actively serve Apache's default 404 page for a number of URLs using mod_rewrite? Not a custom error document, but a rule like RewriteCond %{REQUEST_URI} ^/dirname/pagename RewriteRule -- serve 404 page ----- I guess I could build a PHP page that sends the 404 header and have mod_rewrite redirect all the URLs there but I would prefer a solution that is based on mod_rewrite only. I just had the idea of redirecting to a non-existent address: RewriteCond %{REQUEST_URI} ^/dirname/pagename RewriteRule .* /sflkadsölfkasdfölkasdflökasdf but that would give the user the message "/sflkadsölfkasdfölkasdflökasdf does not exist" on the error page, which looks a bit unprofessional.

  • Suppress "Done, but with errors on page" in IE

    - by calebthorne
    I have a website using lots of jQuery and JavaScript that produces a "Done, but with errors on page" message in the footer of IE. Everything on the site works perfectly, so I don't want to spend the time troubleshooting the exact error. All I would like to do is suppress the "Done, but with errors on page" message so that clients don't freak out. I tried the following at the top of the page with no success: window.onerror = function() {return true;}
