  • Gridview with row being edited causing error when form submitted

    - by Chris Phelps
    Using ASP.NET VB, I have a form with some text boxes and a Gridview. If a user clicks the Edit button on a row in the gridview, and then tries to submit the form with a row still in edit mode on the Gridview, this error is generated - "Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" % in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. " Any idea how to prevent this error??

  • Remove links with Javascript

    - by Arlen Beiler
    How do I remove links from a webpage with Javascript. I am using Google Chrome. The code I tried is: function removehyperlinks() { try { alert(document.anchors.length); alert(document.getElementsByTagName('a')); for(i=0;i=document.anchors.length;i++) { var a = document.anchors[i]; a.outerHTML = a.innerHTML; var b = document.getElementsByTagName('a'); b[i].outerHTML = b[i].innerHTML; } } catch(e) { alert (e);} alert('done'); } Of course, this is test code, which is why I have the alerts and 2 things trying at the same time. The first alert returns "0" the second [Object NodeList] and the third returns "done". My html body looks like this: <body onload="removehyperlinks()"> <ol style="text-align:left;" class="messagelist"> <li class="accesscode"><a href="#">General information, Updates, &amp; Meetings<span class="extnumber">141133#</span></a> <ol> <li><a href="#">...</a></li> <li><a href="#">...</a></li> <li><a href="#">...</a></li> <li><a href="#">...</a></li> <li><a href="#">...</a></li> <li><a href="#">...</a></li> <li><a href="#">...</a></li> <li><a href="#">...</a></li> <li start="77"><a href="#"">...</a></li> <li start="88"><a href="#">...</a></li> <li start="99"><a href="#">...</a></li> </ol> </li> </ol> </body>

  • How to maintain precision using DateTime.Now.Ticks in C#

    - by nmr
    I know that when I use DateTime.Now.Ticks in C# it returns a long value but I need to store it in an int variable and I am confused as to whether or not I can maintain that precision. As of right now I just have a cast int timeStampValue = (int)DateTime.Now.Ticks; Any suggestions or advice on how to maintain the precision, if possible, would be much appreciated.

  • combination of open source licenses

    - by Nicola Montecchio
    Hi I'm about to release some software as open source. It uses Lucene (Apache license) and jopt simple (MIT license). Are there any constraints on the license that I am going to apply to my own software? In particular, it is an adaptation of Lucene for performing content-based search on audio (so, many classes are inherited and in one case copied with a little modification). It only uses jopt simple for handling command line arguments (i.e. no modification at all, just "import" and "new OptionParser..."). Thanks for your help Nicola Montecchio

  • Can you change/redirect a django form's function by passing in your own function?

    - by Derek
    I'm dealing with django-paypal and want to change the button src images. So I went the the conf.py file in the source and edited the src destination. However, I really want to leave the source alone, and I noticed that the class PayPalPaymentsForm(forms.Form): has def get_image(self): return { (True, self.SUBSCRIBE): SUBSCRIPTION_SANDBOX_IMAGE, (True, self.BUY): SANDBOX_IMAGE, (True, self.DONATE): DONATION_SANDBOX_IMAGE, (False, self.SUBSCRIBE): SUBSCRIPTION_IMAGE, (False, self.BUY): IMAGE, (False, self.DONATE): DONATION_IMAGE, }[TEST, self.button_type] which handles all the image src destinations. Since changing this def in the source is worse than changing conf, I was wondering if there was a way to pass in customized defs you make like passing in initial arguments in forms? This way no source code is changed, and I can customize the get_image def as much as I need. passing in def something like this? def get_image(self): .... .... paypal = { 'amount': 10, 'item_name': 'test1', 'item_number': 'test1_slug', # PayPal wants a unique invoice ID 'invoice': str(uuid.uuid4()), } form = PayPalPaymentsForm(initial=paypal, get_image) Thanks!

  • Resizing a rectangular array

    - by devdept
    Does a smarter way than the following exist to resize a rectangular array? double[,] temp = new double[newSize, originalSecondDimension]; Array.Copy(original, temp, original.Length); I was concerned about duplicating a huge array and the memory necessary to do it. What does the Array.Resize() do internally? Thanks, Alberto

  • Getting a pid of a process created in C#

    - by Adrian
    Lets say that I'm trying to create a new process with the following code: System.Diagnostics.Process p = new System.Diagnostics.Process(); p.StartInfo.WorkingDirectory = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase); p.StartInfo.FileName = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) + "\\AwesomeFile.exe"; p.StartInfo.Arguments = "parameter1 parameter2"; p.StartInfo.CreateNoWindow = true; p.Start(); and right in the next line, I'll try to get a pid of that process with the following line: MessageBox.Show(p.Id); This line is giving me the "No process is associated with this object." error. Any idea as to why this error occurs?

  • How to iterate with Selenium RC over XPath results directly?

    - by Gj
    I'm currently resorting to first doing a get_xpath_count, and then creating a loop incrementing an index variable, which in turn I inject back into the original xpath to select the nth result... very awkward no doubt. Is there some simple, direct, elegant way to iterate directly over the xpath results? Thanks!

  • How to invoke a method with a generic return type using reflection

    - by Andre Luus
    Hi there! I'm trying to invoke a method with reflection that has a generic return type, like this: public class SomeClass<T> { public List<T> GetStuff(); } I get an instance of SomeClass with a call to a Repository's GetClass<T> generic method. MethodInfo lGetSomeClassMethodInfo = typeof(IRepository) .GetMethod("GetClass") .MakeGenericMethod(typeof(SomeClass<>); object lSomeClassInstance = lGetSomeClassMethodInfo.Invoke( lRepositoryInstance, null); After that, I this is where I try to invoke the GetStuff method: typeof(SomeClass<>).GetMethod("GetStuff").Invoke(lSomeClassInstance, null) I get an exception about the fact that the method has generic arguments. However, I can't use MakeGenericMethod to resolve the return type. Also, if instead of typeof(SomeClass<>) I use lSomeClassInstance.GetType() (which should have resolved types) GetMethod("GetStuff") returns null! UPDATE I have found the solution and will post the answer shortly.

  • Getresponse not working after authentication

    - by Hazler
    For starters, here's my code: // Create a request using a URL that can receive a post. WebRequest request = WebRequest.Create("http://mydomain.com/cms/csharptest.php"); request.Credentials = new NetworkCredential("myUser", "myPass"); // Set the Method property of the request to POST. request.Method = "POST"; // Create POST data and convert it to a byte array. string postData = "name=PersonName&age=25"; byte[] byteArray = Encoding.UTF8.GetBytes(postData); // Set the ContentType property of the WebRequest. request.ContentType = "application/x-www-form-urlencoded"; // Set the ContentLength property of the WebRequest. request.ContentLength = byteArray.Length; // Get the request stream. Stream dataStream = request.GetRequestStream(); // Write the data to the request stream. dataStream.Write(byteArray, 0, byteArray.Length); // Close the Stream object. dataStream.Close(); // Get the response. HttpWebResponse response = (HttpWebResponse)request.GetResponse(); // Display the status. Console.WriteLine((response).StatusDescription); // Get the stream containing content returned by the server. dataStream = response.GetResponseStream(); // Open the stream using a StreamReader for easy access. StreamReader reader = new StreamReader(dataStream); // Read the content. string responseFromServer = reader.ReadToEnd(); // Display the content. Console.WriteLine(responseFromServer); // Clean up the streams. reader.Close(); dataStream.Close(); response.Close(); The directory cms/ requires authentication, but if I try running this same code somewhere, where authentication isn't needed, it works fine. The error (System.Net.WebException: The remote server returned an error: (403) Forbidden) occurs at HttpWebResponse response = (HttpWebResponse)request.GetResponse(); I have managed in reading data after authenticating, but not if I also send POST data. What's wrong with this?

  • Determine precision and scale of particular number in Python

    - by jrdioko
    I have a variable in Python containing a floating point number (e.g. num = 24654.123), and I'd like to determine the number's precision and scale values (in the Oracle sense), so 123.45678 should give me (8,5), 12.76 should give me (4,2), etc. I was first thinking about using the string representation (via str or repr), but those fail for large numbers: >>> num = 1234567890.0987654321 >>> str(num) = 1234567890.1 >>> repr(num) = 1234567890.0987654

  • Require a default constructor in java?

    - by jdc0589
    Is there any way to require that a class have a default (no parameter) constructor, aside from using a reflection check like the following? (the following would work, but it's hacky and reflection is slow) boolean valid = false; for(Constructor<?> c : TParse.class.getConstructors()) { if(c.getParameterTypes().length == 0) { valid = true; break; } } if(!valid) throw new MissingDefaultConstructorException(...);

  • Is it bad practice to use python's getattr extensively?

    - by Wilduck
    I'm creating a shell-like environment. My original method of handleing user input was to use a dictionary mapping commands (strings) to methods of various classes, making use of the fact that functions are first class objects in python. For flexibility's sake (mostly for parsing commands), I'm thinking of changing my setup such that I'm using getattr(command), to grab the method I need and then passing arguments to it at the end of my parser. Another advantage of this approach is not having to update my (currently statically implemented) command dictionary every time I add a new method/command. My question is, will I be taking a hit to the efficiency of my shell? Does it matter how many methods/commands I have? I'm currently looking at 30 some commands, which could eventually double.

  • Prolog: using the sort/2 predicate

    - by Øyvind Hauge
    So I'm trying to get rid of the wrapper clause by using the sort library predicate directly inside split. What split does is just generating a list of numbers from a list that looks like this: [1:2,3:2,4:6] ---split-- [1,2,3,2,4,6]. But the generated list contains duplicates, and I don't want that, so I'm using the wrapper to combine split and sort, which then generates the desired result: [1,2,3,4,6]. I'd really like to get rid of the wrapper and just use sort within split, however I keep getting "ERROR: sort/2: Arguments are not sufficiently instantiated." Any ideas? Thanks :) split([],[]). split([H1:H2|T],[H1,H2|NT]) :- split(T,NT). wrapper(L,Processed) :- split(L,L2), sort(L2,Processed).
