  • What is more viable to use? Javascript libraries or UI Programming tools?

    - by Haresh Karkar
    What is more viable to use:- Javascript Libraries: YUI, jQuery, ExtJs OR UI Programming tools: GWT, ExtGWT, SmartGWT It has become very difficult to choose between them as they are constantly increasing their capabilities to meet newer requirements. We all know the power of jQuery in UI manipulations. The latest news from Microsoft about jQuery being officially part of .Net developr’s toolkit will definitely make jQuery a preferred choice against other JavaScript libraries [See link: http://weblogs.asp.net/scottgu/archive/2008/09/28/jquery-and-microsoft.aspx]. But on the other hand, GWT is building a framework which could be used on client as well as on the sever side. This is definitely going to make developers’ life easy as it does not require developer to be an expert in browser quirks, XMLHttpRequest, and JavaScript in order to develop high-performance web applications. It includes SDK (Java API libraries, compiler, and development server which allows to write client-side applications in Java and deploy them as JavaScript), Speed Tracer and plug-in for Eclipse. GWT is used by many products like Google Wave and AdWords. So question is still un-answered, what is more viable to use? Any thoughts?

  • Turn off LogEnabled Filter at run time - Logging Enterprise Application Block

    - by Or A
    Hi, so the story go like this: i'm using the Logging Enterprise Application block that provided by microsoft to log events in our application. The goal is to enabled event viewer logging at loading and then turn it off. What i did is to add EventLog TraceListener which write all our logs into the event viewer. What i'm trying to do is to disable it after the application was done loading. The only way that i can thing about is to add a LogEnabled Filter and then turn it off. However, i don't know how to access this filter at run time and disable log on this listener. if you have an idea, please share. Thanks

  • create a simple pdf report from html

    - by opensas
    I'm looking for a way to generate pdf files from html In order to make simple tabular reports I would need the following features table rendering variable page size repeating headers / footers on every page calculated page number / total page css support would be nice I know there have been many similar questions in stackoverflow, but I don't know if there's a product that supports the aforementioned features... Ideally, the source would be a plain and simple well built html with css, (I'm building the html files, so I can adapt to the products needs, that is, it won't have to render every piece of html crap you can throw at a browser) and with some custom tags to configure headings, footer, page size, etc... then I would run a command line to convert it from html to pdf. I think http://www.allcolor.org/YaHPConverter/ does something like that

How to give alert to the user saying that the "textareas are empty" this is a general message but focus on the 2nd textarea and when the user enters data in 2nd the next textarea should be focused. <script> function ad_R(count) { //Adding and populating table row var row = '<tr>'; row += '<td>'; row += '<textarea rows = "8" cols = "18" border ="0" class="input" style="border:none;overflow:visible;width:100%;" id="details'+count+'" nfocus="if (this.value == \'Enter text\') this.value = \'\';" onblur="if (this.value == \'\') this.value = \'Enter text\';" name ="detail'+count+'" class="row_details'+r_count+'">Enter text</textarea></td></tr>'; } $(document).ready(function() { cnt += '<table cellspacing="0" cellpadding="0" border="1" width="100%" id="_table">'; cnt += '<tr>'; cnt += '<th width="30%">Category</th>'; cnt += '</tr>'; for(var i=0;i<6;i++) { cnt += add_R(6); } cnt += '</table>'; });

  • TFS Build Server Cannot find Assembly Reference

    - by Steve Syfuhs
    I looked at this post http://stackoverflow.com/questions/547468/assembly-references-wont-resolve-properly-on-our-build-server but it didn't help the issue. I am (extremely) new to TFS, and just installed 2010 on a VM. I imported a project and got everything working-ish. I went to create a new build through team explorer, and set it up to build on each check-in. It build's locally just fine, but when it's built on check-in it dies on a 3rd party assembly reference. The reference is not in the GAC, but part of the local references. There is only one 3rd party dll, and the projects only reference each other in the solution. I have a feeling I'm missing some important step with regards to TFS and references. Any ideas? EDIT: This a test installation...there is nothing else installed on this box, with the exception of SQL and IIS.

  • Is the Tao framework dead?

    - by Tom Savage
    I'm looking into experimenting with Tao but I am somewhat put-off by it's dead-looking state. It hasn't been updated since 2008 and it looks like their website stopped functioning at roughly the same time. Does anyone have any information on the current situation or know of it's stability?

  • can I override/redefine "global" Javascript functions, like confirm() and alert()?

    - by EndangeringSpecies
    I want to do some browser automation, and those pesky confirm/alert boxes are a real pain. Disabling javascript completely in this case is not an option, unfortunately. Well, so I was wondering, can I just change the definition of those methods as seen by my browser's javascript interpreter to basically do nothing and return true? Note that I do know about redefining them in the Javascript code directly, e.g. putting in function alert(message) { return true; } but AFAIK this is not a viable approach for this situation because when doing browser automation I have to work with other people's Javascript. Moreover, my program actually begins manipulating these websites already after the page has fully loaded into the browser, so I cannot just first automatically rewrite the javascript and then load the page. Well, so I was wondering if I could instead just "permanently" modify the way alert/confirm are implemented and executed in my browser. Sort of like the equivalent of dll injection and so forth in the realm of windows apps.

  • Easiest Java image processing solution

    - by Daniel Fath
    Here is the deal, in my Java project I have to make a composite document that combines both text and images; So I'm looking for a way to manipulate pictures (rotate, change size, that sort of thing). The API I'm looking for should be clear and easy to learn (preferably with some examples), it should cover the basic transformations I made above - rotate,change size, eventually crop.

  • sorl-thumbnail unit tests fail by 1 pixel (!)

    - by stevejalim
    Hi I'm using sorl-thumbnail in a Django 1.2 (currently 1.2 RC) project and getting a surprising failure of four of sorl's built-in unit tests.

  • Libraries for developing NCPDP SCRIPT based systems (a standard for e-prescribing)

    - by Kaveh Shahbazian
    What are (based on experiences) best (commercial or open source) libraries for developing NCPDP-based systems? Background: NCPDP (National Council for Prescription Drug Programs) is a not-for-profit, ANSI-accredited, standards development organization. One of it's standards is the SCRIPT Standard for Electronic Prescribing, which allows PHARMACY, PRESCRIBER (i.e. Physician) and PAYERS (patient or more often insurer) communicate. So the SCRIPT standard is about data transmission. Problem: One step in implementing such systems is to develop models for data based on SCRIPT standard. These models should have utilities for serializing/deserializing to/from SCRIPT binary format and SCRIPT XML format (there are two distinct formats here; both must be supported). Here rises the problem (for me at least). To develop this subsystem for handling the model, implementing serializing and deserializing facilities and keep it uptodate with the SCRIPT standard specifications is a lot of work; it needs it's own team and team management issues (to support a standard implementation). So I am looking for a solution to this problem; to keep standard implementation out of the way and focusing on main problems. Thanks to all (Thankyou Freiheit for your hints!) Edit 2: Thanks to all for help! NCPDP (National Council for Prescription Drug Programs) is an standard for e-prescribing. It defines two formats for message transmission: binary and XML. Implementing XML is somehow easier because it is a standard format which in turn gives us more tooling options. The binary format has a very big specification and time-consuming to implement. I did not find an open source solution to work with. So I am looking for commercial alternatives. Edit 1: Please guide me; what's wrong with this question?

  • Create a string with the result of an expression and the expression that originated the value. Is it

    - by Oscar Reyes
    Like String r = SomeThing.toExecString("new Object().toString()"); And when executed the value of r would be: "new Object().toString() = java.lang.Object@c5e3974" Is this even possible at all? Would it need a bunch of reflection? A built in compiler maybe? AFAIK, this is not possible with regular Java. The closest thing I could get is IDE support like in IDEA with the "macro" soutv+tab that prints: Hit taband type the expression The IDE types the rest for you. But that's quite another completely thing.

  • Why do the overloads of String.Format exist?

    - by GiddyUpHorsey
    I was using Reflector to look at the implementation of String.Format and had always been under the impression that the overloads of String.Format that took 1, 2 & 3 arguments were optimized versions of the method that takes an object array. However, what I found was that internally they create an object array and then call a method that takes an object array. 1 arg public static string Format(string format, object arg0) { if (format == null) { throw new ArgumentNullException("format"); } return Format(null, format, new object[] { arg0 }); } 2 args public static string Format(string format, object arg0, object arg1) { if (format == null) { throw new ArgumentNullException("format"); } return Format(null, format, new object[] { arg0, arg1 }); } 3 args public static string Format(string format, object arg0, object arg1, object arg2) { if (format == null) { throw new ArgumentNullException("format"); } return Format(null, format, new object[] { arg0, arg1, arg2 }); } Object array public static string Format(string format, params object[] args) { if ((format == null) || (args == null)) { throw new ArgumentNullException((format == null) ? "format" : "args"); } return Format(null, format, args); } Internally they all end up using the same code and so using the 1, 2 & 3 argument versions are no faster than the object array version. So my question is - why do they exist? When you use the object array version with a comma separated list of values, the compiler automatically converts the arguments into an object array because of the params/ParamArray keyword which is essentially what the 1, 2 & 3 versions do, so they seem redundant. Why did the BCL designers add these overloads?

  • Should I post my PDF library for SEO? [closed]

    - by Iunknown
    Possible Duplicate: Do search engines crawl PDFs and if so are there any rules to follow when making them When a Sales call comes in, the caller often says something like: 'I searched for 3 days before finding your product and it's exactly what I need!' That's telling me that I need some SEO work. We redid our website and streamlined it which removed many of our 'How-To' documents. Since those PDF documents contain words that people might search for, I was wondering if I could add a 'Complete library' link to the bottom of a page that will load up the entire PDF library. Would that help my ranking?

  • Are there any 3rd Party libraries for image processing in C#?

    - by Gaax
    Just wondering if there's anything out there to help make my project a lot easier to deal with. I'm working on a program that uses the Wiimote and infrared pen (mapped to the mouse) to manipulate images in real time and I'd much rather not have to use all my time figuring out how to make the program resize and rotate images efficiently with the least amount of distortion... I haven't really found anything when searching. Anybody know of any libraries that can help me?
