HelloTXT is a very cool service that can post your updates to multiple social networks with a single click. You can feed it data in multiple ways from RSS feeds to Android phones. One such way is a small neat WordPress plugin by Matthew Phillips. Once installed in your blog it will ping HelloTXT whenever you write a new post, notifying all your connected services from Facebook to Twitter.
One small drawback of v1.0.1 of this plugin (current as of this writing) – if permalink URL of your post is very long (pretty ones tend to be) – it gets cut off during HelloTXT notification, since status update has to be within 140 characters length. But there’s an easy solution. Open PHP source of the plugin in any text editor and in function hellotxt_notification locate line:
$link = get_permalink($post->ID);
This is the line that gets permalink of your post. To replace it with shortened URL we can call API of TinyURL service:
$link = file_get_contents("http://tinyurl.com/api-create.php?url=".get_permalink($post->ID));
and Voila! short links are being sent to HelloTXT
If after upgrading to a new version of Infragistics NetAdvantage you suddenly found your WHDG sprouting an extra blank row on top:
most likely it’s because grid’s ItemCssClass property is used. In theory (at least according to ever so verbose documentation) it should define what grid’s cells look like. In practice it have no effect whatsoever. Or rather had no effect until upgrade (verified in version 2011.1, perhaps even earlier). Now if your CSS class used in this property contains HEIGHT attribute – a blank row of that height will be inserted on top of the grid.
Solution? Remove ItemCssClass property. It’s useless anyway.
This is the second post in saga titled Upgrading Infragistics Controls to a new version. Chances are that your WebDataMenu looks weird after upgrade to 2010+ version. In my case the menu had following options/features:
- It was a context popup menu, called on right mouse click
- Text of menu items was assigned dynamically at runtime in JavaScript Client code
After upgrading NetAdvantage from version 2009.2 to 2011.1 strange things started to happen. Text of the menu items was cut short, submenues appeared at wrong places it looked like something from a Dali’s painting.
Numerous experiments later I found out that the problem was with EnableScrolling property of the menu control. Setting it to False returned menu to realm of realism.
Upgrading 3rd party library to a new version is bound to have problems and Infragistics is no exception. In my case I was upgrading NetAdvantage for ASP.NET from version 2009.2 to to 20011.1 and right away WebHierarchicalDataGrid started to crash client-side. If ScriptManager was in debug mode I’d get error:
Microsoft JScript runtime error: Sys.ArgumentUndefinedException: Value cannot be undefined.Parameter name: type
With ScriptManager in Release mode it’d be:
Microsoft JScript runtime error: Object expected
But always in Sys.Component.Create – it looked like grid’s client-side scripts weren’t loading at all. After A LOT of digging I found out that the culprit was grid’s server-side Bands.Clear() method. When called, it caused client-side WHDG JavaScript not to load. When that method was commented – JavaScript errors disappeared. So until Infragistics comes out with a bug fix – if you experience similar problem, try to avoid Bands.Clear() method.
I am using FeedWordPress plugin on some of my sites to pull data from Google News RSS feeds. It was working fine, but after I moved to a new host, I started to get errors like:
Failed to connect to 2a00:1450:8006::63: Network is unreachable
Note the IPv6. Google have been supporting it for a while and news.google.com resolves to IPv6 first (similar error happens in WordPress admin dashboard in “Incoming Links” section). Unfortunately network of my new host didn’t support IPv6, so I had to find solution to force WordPress to use IPv4. Enter class-http.php.

If you’re using Crystal Reports 2008 in your ASP.NET application, and after deploying to a 64bit server getting following error:
An error has occurred while attempting to load the Crystal Reports runtime. Either the Crystal Reports registry key permissions are insufficient, or the Crystal Reports runtime is not installed correctly. Please install the appropriate Crystal Reports redistributable (CRRedist*.msi) containing the correct version of the Crystal Reports runtime (x86, x64, or Itanium) required. Please go to http://www.businessobjects.com/support for more information.
then switch your application to 32bit mode. In case of Windows 2003/IIS6 entire server will have to be switched, in case of Windows 2008/IIS7 a dedicated 32bit application pool can be established for your application.
Scenario: You’re trying to update a template file in your PHPBB 3.0.x forum, for example to include Google Adsense code into overall_header.html file to display banner on top of all the pages. But after modifying and uploading the file nothing changes, board still displays old template.
What is happening – PHPBB displays cached version of the template. Forum software caches commonly used files to improve performance. The solution is to purge cache.
Login to your forum Administration Control Panel and click Run Now in Purge the cache section. After purging is complete changes in your template take effect.
Often there is a need to add client-side Javascript to the ASP.NET page from server-side code. To perform additional manipulation on rendered controls (hide or disable), to show user an alert message – just a couple of examples. Standard ASP.NET approach is to use page’s client script manager’s RegisterStartupScript method:
Me.ClientScript.RegisterStartupScript (Type, Key, Script, AddScriptTags)
Where
type: The type of the startup script to register.
key: The key of the startup script to register.
script: The startup script literal to register.
addScriptTags: A Boolean value indicating whether to add script tags.
For example:
Me.ClientScript.RegisterStartupScript (Me.GetType(), "alert", "alert('Hello world!');", True)
But if you’re using Infragistics controls that offer async postbacks, like WARP panel or UltraWebTab – there is a problem with this approach. Since the page doesn’t go through the full postback and doesn’t get destroyed and re-rendered from scratch – this method doesn’t work.

Infragistics WebDataMenu is a light-weight highly responsive menu control with rich server and clinet side model. I was using it to display context menu on right mouse click. The code is pretty simple:
function onMouseClick(oEvent) {
if (oEvent.button == 2) { //right mouse button clicked
var menu = $find("xwdmMyMenu");
menu.showAt(null,null, oEvent);
}
}
It checks whether the right mouse button was clicked (line 2) then locates the menu object and shows it using showAt method (which accepts 3 parameters, either X and Y client coordinates, or event object from which it derives coordinates of the mouse click).
It’s all well and good, but the problem is – menu always shows down from the location of the mouse click. And if the click is at the bottom of the screen – menu gets cut off:
I needed to make menu expand UP and couldn’t find a build-in property or method that would change this behaviour (GroupSettings.ExpandDirection property had no effect). Time for a little hack. Continue reading 'Infragistics WebDataMenu: Expanding context menu UP'»
I was using Infragistics drag-and-drop framework and set an HTML table element as my drop target. Now I needed to know during drag operation over which HTML table cell I am moving. I needed that in order to dynamically change appearance of draggable markup depending on which cell I am currently over.
(Think a strategy game – you’re placing construction on the terrain – if there is enough unoccupied room – the draggable item becomes green, otherwise it remains red).
The solution is to use elemAtPoint property during DragMoveHandler event. Continue reading 'Infragistics Drag and Drop: detecting element during drag'»
