Having recently updated an ASP.net MVC web app from MVC4 to MVC5 and from .NET 4.5 to .NET 4.7.2 I was expecting Razor views (.cshtml files) to use the latest C# compiler, especially since at Properties/Build/Advanced option for the web project one read “C# latest major version (default)”. However that was not the case and […]...

I’m often asked by friends and family to assist them on frustrating technical issues they can’t resolve by themselves. Thanks to remote access / support software like TeamViewer, this is a piece of cake nowadays. The solution to such problems isn’t always straightforward though. Just came across a Microsoft Word installation where suddenly the Print […]...

Based on Sam Holder’s answer at https://stackoverflow.com/questions/7388475/reading-int-values-from-sqldatareader/54296026, just contributed an extension method for fetching Int32 values via ADO.net’s SqlDataReader, without jumping through hoops (aka first fetch column ordinal [number] by name, then fetching the int value passing the column ordinal). Would be nice if Microsoft was providing such things out of the box. namespace adonet.extensions […]...

Azure Storage is a cloud storage solution for data storage scenarios and one key service, among others, is Azure Blobs, a scalable object store for text and binary data. A main use is to upload files to it, either as a long term backup solution, or as a way to serve documents, images and videos directly to a browser. To do so, you......

A colleague noticed earlier on today, that on the Chrome browser they were using, the search operator menu items of a jqGrid on a web app’s UI were jumping around on hover, making it practically impossible to select one. Seems this had started occurring on that ASP.net MVC web application, after a recent update […]...

If you need to customize the colors (or do more restyling) of validation messages in ASP.net MVC, the following snippet from a discussion on ASP.net forums should be useful: Add to Content/Site.css: /* styles for validation helpers */ .field-validation-error { color: #b94a48; } .field-validation-valid { display: none; } input.input-validation-error { border: 1px […]...

If you use Joomla! (CMS / Content Management System), you could switch to the free OpenStreetMaps instead of the recently-turned-much-more-expensive Google Maps, thanks to the OSModul extension for Joomla!: https://extensions.joomla.org/profile/extension/maps-a-weather/maps-a-locations/osmodul/ At the bottom of this page there is an example that uses a pin icon similar to how a location would appear in Google Maps.

Today we will discuss another common case, how to create a progress bar to notify our web users about the state of their long running tasks. For this discussion we will work with DevExpress XAF Business Application Framework. We will develop ONE SMALL CLASS, we can then copy paste to any XAF project . It is a good idea before starting any work to search the Support Center for ideas and ask the DevExpress support guys. Doing so we found many tickets with ready to work solutions. Some of them are good candidates e.g How to start a long running operation in ASP.NET application using the ThreadPool.QueueUserWorkItem method and show its progress in a browser using a WebService method . The problem with the previous sample , is that uses a WebService to periodically call back in a Controller. I wanted to create a reusable implementation inside a library and a WebService cannot live in a library . But I got the idea on how to proceed . I just need to create a ViewItem to host a ASPxProgressBar and with periodic call-backs...

The other day I found how easy it is to use a Live CD/DVD (where packet writing occurs when adding stuff) instead of a Mastered one (where all is kept to be written when you close the disk) on Windows. It feels more like using a USB flash disk and should be more safe regarding […]...

Just came across this validation error display in an MVC app I’ve recently started maintaining. The required input field validation seemed to not be localized, resulting in a mixed English and Greek (from the field’s Display name) message: Looking at the MVC model I noticed they were using [Required] attributes for the userName and password […]...

Lately, I’ve got the task of maintaining/extending an ASP.net MVC web application that is using jQuery’s jqGrid for data grids on its UI. First thing I noticed was how confusing the search UI on the grid’s header was: Those symbols on the left-side of each column’s searchbox are for the type of search (e.g. contains, […]...

Microsoft is suggesting to always use Named parameters with SqlCommands for security reasons (to avoid SQL injection exploits), but they haven’t thought of providing a property at SqlCommand to give you back the result SQL so that you can have your app log it without resorting to SQL Server for that logging. Found a solution […]...

It seems VBScript (.vbs) script file’s DropHandler on Windows is broken regarding Unicode filenames, as described at https://stackoverflow.com/a/4366906/903783 A workaround suggested by user DG there (https://stackoverflow.com/a/13587850/903783) was to use a batch file to accept the dropped file, then pass the filename(s) to the VBScript script file (.vbs) as command-line parameters. If you just care about […]...

Just came across the following case in C# that puzzled me momentarily, especially since the strings involved were long enough and the expression was broken on multiple lines: bool flag = true; string test1 = flag? "xa" : "xb"; string test2 = "x" + (flag? "a" : "b"); string test3 = "x" + flag? "a" […]...

Today I will detail about implementing Scheduled Long running tasks in an abstract and reusable way. The Requirement Usually, I have a business objects that store time depended data e.g. Exceptions, Logs etc. There is a need to periodically clean up those tables. The parameters First we need to identify the problem parameters so we can create a model interface . Parameterizing the problem in a model interface is very useful, because the end user can switch it off if something goes wrong. Parameters will be: the business object type which we want to clear its records, the criterion to filter the objects and the time to execute this action. The interface along with its registration for this is bellow. using System; using System.ComponentModel; using DevExpress.ExpressApp; using DevExpress.ExpressApp.Model; using DevExpress.ExpressApp.Model.Core; namespace PurgingRule.Module.Controllers{ //rules container public interface IModelClassPurgingRules:IModelClass{ IModelPurgingRules PurgingRules{ get ; } } [ModelNodesGenerator(...
