OpenLayers is a fine alternative to the map visualization part of Google Maps Platform, however many of its examples sometimes use features from future and server-side Javascript versions, like “imports”. Based on lou’s answer at https://stackoverflow.com/questions/51093964/why-examples-dont-work-a-struggle-with-imports/56549364, here’s a fix I just did to make the Marker animation example work when you just copy-paste the example […]...

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 […]...

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 […]...

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...

Just came across this validation error display in an MVC app I’ve recently started maintaining.

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.

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 […]...
