  • Runtime Error in asp.net site?

    - by Surya sasidhar
    hi, I developed a website in asp.net and i place the site in online. I upload my site in online by using CuteFTP. After uploading when i type my url it is giving error like this... Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.

  • What does :this means in Ruby on Rails?

    - by Marco
    Hi, I'm new to the Ruby and Ruby on Rails world. I've read some guides, but i've some trouble with the following syntax. I think that the usage of :condition syntax is used in Ruby to define a class attribute with some kind of accessor, like: class Sample attr_accessor :condition end that implicitly declares the getter and setter for the "condition" property. While i was looking at some Rails sample code, i found the following examples that i don't fully understand. For example: @post = Post.find(params[:id]) Why it's accessing the id attribute with this syntax, instead of: @post = Post.find(params[id]) Or, for example: @posts = Post.find(:all) Is :all a constant here? If not, what does this code really means? If yes, why the following is not used: @posts = Post.find(ALL) Thanks

  • Regex for xml parsing

    - by ogmios
    What is your opinon about following regexes - is it correct? To find element with spcific and required attribute "<(" + elem_name + ")(\s+(?:[^<]?\s+)" + attr_name + "\s*=\s*(['\"])((?:(?!\3).))\3[^<])(.*?)" To find element with spcific but optional attribute "<(" + elem_name + ")(\s*|\s+(?:[^<]?\s+)(?:" + attr_name + "\s*=\s*(['\"])((?:(?!\3).))\3)?[^<])(.*?)" Pleas not another answer "use existing xml parser". Question is - are the regexes proper or not? This is specific situation - C language in embedded system and xml is not well-formed (cannot be fixed - does not depend on me). Xml have specified schema and no problem with namespaces etc. exists.

  • Opening all external links in Phongap's ChildBrowser using jQuery Mobile

    - by Adam
    I'm using jQuery Mobile & Phonegap, and have the following code to open all external links in a certain div with the ChildBrowser: $('.someDIV a').live('click', function() { var thisUrl = $(this).attr('href'); PhoneGap.exec("ChildBrowserCommand.showWebPage", thisUrl); return false; }); For some reason, while the page loads in the childbrowser, it also loads in the background, as if there's no "return false". I've found a workaround by giving the link's href attribute a value of "#", and using the title for the url like this: And updating the jQuery code accordingly, but this is a problem where my links are dynamically generated, and I can't have the url in the title attribute. Any ideas how to solve this?

  • Visual Studio 2010 Not Recognizing Unit Test

    - by jmease
    In an existing solution I added a new Test Project. In my Test Project .cs file I have a class decorated with the [TestClass] attribute and a method decorated with the [TestMethod] attribute. I have verified that in Configuration Manager the build check box is checked for the Test Project (as my google search has revealed was the problem for others with this issue). I have set Test Project as my start up project for the solution. When I try to start the test I get "Can not start test project because the project does not contain any tests". I am really new to unit testing. What am I missing?

  • How can I strip line breaks from my XML with XSLT?

    - by Eric
    I have this XSLT: <xsl:strip-space elements="*" /> <xsl:template match="math"> <img class="math"> <xsl:attribute name="src">http://latex.codecogs.com/gif.latex?<xsl:value-of select="text()" /></xsl:attribute> </img> </xsl:template> Which is being applied to this XML (notice the line break): <math>\text{average} = \alpha \times \text{data} + (1-\alpha) \times \text{average}</math> Unfortunately, the transform creates this: <img class="math" src="http://latex.codecogs.com/gif.latex?\text{average} = \alpha \times \text{data} + (1-\alpha) \times&#10;&#9;&#9;&#9;&#9;&#9;\text{average}" /> Notice the whitespace character literals. Although it works, it's awfully messy. How can I prevent this?

  • Get name and value from the input tag

    - by DroidIn.net
    Before you say "oh no, not again" here I'm stating my case. I'm parsing part of HTML output and the only thing I'm interested in is name and value attributes of each <input/ tag. HTML is actually HTML fragment, may not be well-formed. I don't have DOM or HTML parser and I don't try to parse nested elements anyway. The problem is that I don't know the order or number of attributes so it could be <input name="foo" value="boo"/> or <input type="hidden" name=foo> or <input id=blah value='boo' src="image.png" name="foo" type="img"/>. Is there a single regular expression that would get me values of name and value attribute in predictable order? I wouldn't have asked the question if I could assume that name attribute always precedes value but unfortunately this is not the case

  • ASP.NET MVC2 - Trim white space from form submits before server-side validation?

    - by David Lively
    If I add a validation attribute: public class ProductDownloadListModel { //xxxxx-xxxxx-xxxxx [Required] [StringLength(17)] public string PSN { get; set; } public DateTime PsnExpirationDate { get; set; } public DataTable Downloads { get; set; } } and the user enters a 17-character string but includes white space on the end, I get a validation error because the string is greater than that specified by the [StringLength(17)] attribute. How can I prevent this? I'd prefer not to have to have javaScript trim the string before submits.

  • Is this a good approach to execute a list of operations on a data structure in Python?

    - by Sridhar Iyer
    I have a dictionary of data, the key is the file name and the value is another dictionary of its attribute values. Now I'd like to pass this data structure to various functions, each of which runs some test on the attribute and returns True/False. One approach would be to call each function one by one explicitly from the main code. However I can do something like this: #MYmodule.py class Mymodule: def MYfunc1(self): ... def MYfunc2(self): ... #main.py import Mymodule ... #fill the data structure ... #Now call all the functions in Mymodule one by one for funcs in dir(Mymodule): if funcs[:2]=='MY': result=Mymodule.__dict__.get(funcs)(dataStructure) The advantage of this approach is that implementation of main class needn't change when I add more logic/tests to MYmodule. Is this a good way to solve the problem at hand? Are there better alternatives to this solution?

  • Need recommendation for object serialization library in c++

  • Having trouble applying style to SVG using JavaScript upon object creation

    - by Jack Roscoe
    Hi, I have a function which creates an SVG text object using JavaScript. As soon as the object is created, I want it to have the style attribute which in CSS would be text-anchor: left. Currently, it doesn't work. I have tried many variations, and I also read that when using styles in JavaScript you must remove any '-' dashes and format the attribute name in camel casing (is this true?). Can anybody spot my mistake? Here's my code: RenderTextBox:function() { this.textBox = paper.text(this.x, this.y, this.htmlTextBox); this.textBox.style.textAnchor="left"; }

  • jquery: .attr() fails for child element

    - by user984003
    I'm going crazy staring at this. I need to change the attribute of an element, something which I have done many times before. But it fails. Now I can't even get jquery to show me the attribute that it has. Does it have to do with what is returned by find()? var c = new_photo_div.find('[class = photo]')[0]; alert(c); alert(new_photo_div.attr('class')); alert(c.attr('class')); The first alert correctly identifies the element: Object HTMLImageElement The second alert correctly gives me the class of new_photo_div. The third alert fails. No alert. I think it should say: photo

  • Why does this PNG file look so poorly when embedded as a resource in a Qt project?

    - by George Edison
    Here is the PNG file and what it looks like in a QWebView when accessed via http://sstatic.net/so/img/logo.png: When accessed via HTTP: <img src="http://sstatic.net/so/img/logo.png" width='250' height='61' /> When accessed via a resource: <img src="qrc:/images/logo.png" width='250' height='61' /> As you can see, the only modification was the src attribute of the image tag... why the drop in quality? Edit: The file is being shrunk via width: and height: in the style attribute, if that makes a difference. I updated the code.

  • MVC Helper Extension issue

    - by BeCool
    Hi, I need to implement a HtmlHelper extension in my MVC project simply just to output some string but ONLY in the DEBUG mode, not in REALEASE. My first attempt would be: [Conditional("DEBUG")] public static string TestStringForDebugOnly(this HtmlHelper helper, string testString) { return testString; } But obviously that would give a compile error: "The Conditional attribute is not valid because its return type is not void." So my understanding is once you set [Condition] attribute, it doesnt allow to return anything? why? What is other way to implement this kind of function? anyone help would be much appreciated. Thanks!

  • how does [<Literal>] differ from other constants in F#

    - by Mitzh
    I am a bit confused by the Literal keyword and why it is necessary in F#. Reading the docs, it sounds to me that [<Literal>] is used to define a constant, however I am a bit confused how this constant differs from all other constants in F#.. Values that are intended to be constants can be marked with the Literal attribute. This attribute has the effect of causing a value to be compiled as a constant. When I think of a constant, I think of something which is immutable.... let x = "a" + "b" //this is a immutable value, its value is constant [<Literal>] let y = "a" + "b" //this is also a immutable value, but why is this a special constant? Is it because the 'normal' F# values are evaluated lazily and the [<Literal>] is not evaluated lazily..? is that what they mean with 'compiled as constant'..? or is there something else to it?

  • jQuery selector to target any CSS name (of multiple present) starting with a prefix?

    - by John K
    I'm considering one selection statement that would target one of many css class names in a single class attribute value based on a string prefix. For example, I want any detail- prefixed class names to get targeted from the following sample links. <a href="eg.html" class="detail-1 pinkify another"> <a href="eg.html" class="something detail-55 minded"> <a href="eg.html" class="swing narrow detail-Z"> <a href="eg.html" class="swing narrow detail-Z detail-88 detail-A"> It's reminiscent of how [class|="detail"] prefix selector works on a scalar attribute value, and also of .hasClass(className), but my question needs both concepts applied simultaneously. Note: The detail- prefix won't necessarily be the first class name of the bunch.
