At ClipFlair’s AudioRecorderControl (used in Captions/Revoicing component of ClipFlair Studio), I use the following code to initialize a MediaElement to use for playback.

at http://zachis.it/blog/7-dangers-of-using-windows-server-on-a-wordpress-installation/ the thing that guy says about Permalinks isn’t accurate at all (not that the other things that he says are any accurate that is). WordPress Codex have documentation on how to configure URL rewriting in web.config that is necessery for Permalinks to work in IIS. ...

Just fixed a nasty bug in ClipFlair Studio (http://studio.clipflair.net), where one couldn’t click hyperlinks in the Text component when set at ReadOnly mode. In that mode hyperlinks should open up new web pages (in Edit mode you can edit/remove them only of course), but instead when clicked they would show something like a focus rectangle ...

PivotViewer is an impressive Silverlight control (see my usage at http://gallery.clipflair.net), however Microsoft never released it for WPF. One could work arround this by embedding Silverlight in their WPF app using the WebBrowser control and talking to it via the JavaScript Bridge of Silverlight, however they could also embed one of those HTML5 ...

I just noticed that on Internet Explorer 11 developer tools console (appears when you press F12 key), there is a drop-down where you can select the rendering engine used. Edge means the very latest (IE11 one in this case) and you can select back to version 5. Interestingly, there is no version 6 in the […]

While trying to generate a single HTML page that will list all ClipFlair activities using XSL Transformations (XSLT), I had the need to group items in 2-column rows. This is my contribution to other solutions suggested at (if you like it you can vote it up there): ...

In C/C++ and C# one has useful prefix (++index) and postfix (index++) increment operators and corresponding decrement ones. Although they have a single operant, they’re not working like functions as single + or – prefix would do, but instead they cause side-effects – they edit the variable passed to them. The prefix increment operator first ...

Trovigo.com is an unwanted search engine hijacker that renders Internet Options of Windows / Internet Explorer inaccessible.

When you try to run a ClickOnce Windows application from Mozilla Firefox, on some machines you may see it try to save a .application (ClickOnce deployment manifest) instead of running the ClickOnce application installer/updater/launcher. To fix that issue you can open Firefox add-ons dialog and search among available to download/install add-ons ...

I was recently adding drop-files support to ClipFlair Studio, so I had to do some research on the related API that is available to Silverlight apps. Silverlight supports a limited set of Drag-and-Drop interaction with the operating system (supposedly for security reasons, but most probably because of the classic cross-platform implementation ...

It seems that CaptureMouse is behaving differently in WPF and Silverlight, in that in the former one it immediately calls OnLostMouseCapture at a Visual, whereas in Silverlight it doesn’t get called if the element didn’t have the mouse capture already (btw, in Silverlight that method is at a UIElement – there is no Visual ...
