Synchronous and Asynchronous Event Handlers

In SharePoint 2010 it is possible to handle events that occur on list items. These types of events come in two types: Synchronous and Asynchronous Event.

• Synchronous: happens 'before' the actual event, you have the HttpContext and you can show an error message in the browser and cancel the event


• Asynchronous: happens 'after' the actual event, there's no HttpContext  and you cannot directly show an error message or cancel the event

By sub-classing Microsoft.SharePoint.SPItemEventReceiver you can override the desired "event" methods.

• Synchronous: methods ending with '-ing' (ItemAdding, ItemUpdating, ...)


• Asynchronous: methods ending with '-ed' (ItemAdded, ItemUpdated, ...)

If you implement an override method you might want to place your code between the following lines to avoid raising other events unwantedly (and possibly causing an infinite loop).

this.DisableEventFiring(); 
... 
this.EnableEventFiring();

Each override method has a parameter of type Microsoft.SharePoint.SPItemEventProperties that contains the item and event properties available for use. There's a bug in the SPItemEventProperties.AfterProperties dictionary that appears empty for synchronous events but it isn't. You can iterate over the dictionary to read and write to this collection ! This means that you can modify some of the inputted metadata before the actual item is stored in the list.

The thing to remember here is that the dictionary uses the field internal name as key, so field 'Field' could have an internal name such as 'My_x0020_custom_x0020_field'.

Make Windows 8 Boot Directly To Desktop

Would you prefer to have Windows 8 bypass the Start Screen and boot straight to the desktop? If so, you can do so using a technique that takes advantage of a feature that is built right into the operating system - no third-party tools required. All you have to do is create a specially configured task that is scheduled to run at log on.

In this post, I’ll walk you through the steps required to make Windows 8 boot straight to the desktop using a specially configured scheduled task.

As you may recall, in previous versions of Windows, a special shortcut called Show Desktop appeared on the Quick Launch menu. This shortcut was a standard text file that contained five lines of code and was saved with the file extension SCF. The fifth line of that code wasCommand=ToggleDesktop.

To begin you’ll need to launch the Task Scheduler tool. To do so, just press the [Windows] key, type Schedule, select Settings, and click Schedule tasks, as illustrated in Figure A. When you do, the Task Scheduler will appear.

[caption id="attachment_3" align="alignnone" width="594"] Task Scheduler[/caption]

Configuring Task

Once you have the Task Scheduler up and running, you’ll begin by clicking the Create Task command in the Actions panel, as shown in Figure B.

[caption id="attachment_4" align="aligncenter" width="594"] Create Task Command[/caption]

When the Create Task dialog box appears, you’ll see that the General tab is selected and will first assign the task a name in the Name text box. As you can see, I choose Show Desktop @ Start. Then, towards the bottom of the page, select Windows 8 from the Configure for drop down menu, as shown in Figure C. You can leave the Security options set to Run only when user is logged on.

[caption id="attachment_5" align="aligncenter" width="594"] Creating a Task[/caption]

To continue, select the Triggers tab to access that page, as shown in Figure D. Now, click the New button towards the bottom of the page.

[caption id="attachment_6" align="aligncenter" width="594"] Trigger Command Page[/caption]

When you see the New Trigger dialog box, select the At log on item from the Begin the task drop down menu, as shown in Figure E. As soon as you do, the New Trigger page will refresh and display the settings for the At log on option, as shown in Figure F.

[caption id="attachment_7" align="aligncenter" width="594"] When Command Triggered Selection[/caption]

[caption id="attachment_8" align="aligncenter" width="594"] Command Triggered when User Log On[/caption]

By default, the Any user option in the Settings panel and the Enabled check box in the Advanced Settings are selected. Just leave them as they are and click OK to continue. When you return to the Create Task dialog box, select the Actions tab, as shown in Figure G. Then, click the New button towards the bottom of the page.

[caption id="attachment_9" align="aligncenter" width="594"] Command Action[/caption]

When you see the New Action dialog box, you’ll find that the Action setting is by default set to Start a Program. So, in the Settings panel, you can just type c:\Windows\explorer.exe in the Program/script text box, as shown in Figure H. You can also use the Browse button to locate and select the explorer.exe program. At this point, just click OK to return to the Create Task dialog box.

[caption id="attachment_10" align="aligncenter" width="468"] Specify Action Path[/caption]

Now, IF you are running Windows 8 on a laptop, select the Conditions tab and in the Power panel, clear the Start the task on if the computer is on AC power check box, as shown in Figure I.

[caption id="attachment_11" align="aligncenter" width="594"] Creating a Task[/caption]

There is nothing that you need to change on the Settings tab so, at this point, you are done and can just click the OK button to complete the scheduled task operation. When you return to the Task Scheduler window, you’ll see the new task that you just created on the Task Scheduler Library, as shown in Figure J. You can now close Task Scheduler.

[caption id="attachment_12" align="aligncenter" width="594"] Schedule a Task[/caption]

Your task is done now. When Windows 8 restarts, you’ll immediately see the Desktop with a File Explorer window targeted on Libraries, as shown in Figure M. You will not see the Start Screen at all.

(Keep in mind that when you see the File Explorer window targeted on Libraries, the Documents Music, Pictures, and Video icons may shuffle around a bit. The reason for this is because when the File Explorer window appears on the screen, the operating system is still doing a bit of housework in the background.)

First 9 things required to set as default setting in MS Word 2013

Everyone wants to work with latest software and make themselves upgraded with latest functionality. MS Office came up with 2013 version and it requires some default setting to make your document unchanged in other office version.

Now, the changes I make may not make sense for you and I am not suggesting that everyone do exactly what I do, but I am suggesting that you take a few minutes to adjust the default settings in MS Word 2013 to make it work the way you want it to work - at least as best you can. And, I mean before you starting using it, not after. A few minutes now can save you some frustration later.

Change the Normal Template

This suggestion is probably the most obvious and the most often overlooked. I don’t like the default font and spacing in Word. Personally I like the Arial font instead of Calibari and I like my paragraphs spaced evenly, so I change the default Normal Template (Figure A) right away.

Fig. A - The default Normal Template

Right-click the Normal Style in the Ribbon to get to the Modify Style options screen shown in Figure B. I change the font to Arial 10.

Fig. B - Change the Font

Fig. C - Change the Spacing

Click OK a few times to put the modifications into action. Remember to click the New documents based on this template radio button to make this your permanent Normal Template.

Word Options

This next set of modifications is very subjective - I make them because it makes my life as an editor easier. Reviewing the options may give you some ideas that will increase your productivity.

Formatting Marks

As an editor, I need to see every character on the page, even if the character is a blank space, so I always turn on all formatting marks. Click File in the menu bar and navigate down to the Options link to reach the Word Options configuration screen (Figure D). Click on the Display tab to reach the formatting marks settings. Click the Show all formatting marks check box.

Fig. D - Formatting Marks

Turn off Smart Quotes

Smart Quotes look great when you are in Word, but they don’t play well with WordPress and the other tools I have to use to publish content on TechRepublic, so I always turn them off. This is a two-step process, which makes it slightly tricky.

Under the Proofing tab you will see a button with the label: Auto Correct Options. When you click that button you are taken to the Auto Correct configuration screen. Click the Auto Format tab (Figure E) and deselect the Replace Straight quotes with smart quotes check box. For good measure, I also unchecked the boxes for Ordinals, Fractions, and Hyphens.

Fig. E - No Smart Quotes for me

Here is the slightly tricky part, you also have to look under the Auto Format As You Type tab and unchecked the appropriate check boxes under the Replace as you type category (Figure F). Click OK to apply the changes.

Fig. F - Also under replace as your type

Advanced Changes

One of the features Word employs to purportedly make our lives easier is called “smart” selecting. I hate it. I much prefer to select what I want to select without Word presuming I want a whole word or sentence or paragraph. Perhaps you like this feature, but it is not for me.

Under the Advanced tab of Word Options (Figure G), you will see several check boxes regarding selecting. I turn off selecting the entire word, and smart paragraph selection. I also typically click the check box that turns on Use Normal style for bullet-ed or numbered lists.

Fig. G - I prefer manual selection

This next change is really just for editing purposes, so it may not apply to you, but it is still good to know where the feature is located in case you ever need it. Further down the page under the Advanced tab there is an item that says: Style area pane width in Draft and Outline views (Figure H). I change that from zero to one inch. That change will reveal the style name used for each section of your document. Click OK to apply all of your changes.

Fig. H - Reveal your style

Quick Access Toolbar

As part of the ribbon interface, in the upper left corner, Word has a feature called the Quick Access Toolbar. However, the default configuration for that feature is, to put it politely, sparse: Save, Undo, and Redo.

While there are many tools and features to choose from when adding to the Quick Access Toolbar

(Figure I), I start with four obvious ones. No doubt, I will add more, as I am sure you will too.

• Quick Print
• Print Preview
• Spelling & Grammar Check
• Draft Mode
• Save

Fig. I - Expand Selections on the quick access toolbar

Adding Quick Print, Print Preview and Spelling and Grammar is very simple: click the down arrow on the Quick Access Toolbar to reveal a list of potential tools and click the appropriate entries on the list.

Adding Draft mode is a little more complicated. There are several ways to accomplish the task, but the easiest way is to click the View tab (Figure J) and then right-click the Draft icon and select the Add to Quick Access Toolbar item.

Fig. J - Add Draft Mode

Set Zoom

The last thing I do depends on the display screen I am working on at the time. For large monitors, I change the Zoom factor to a higher percentage. The Zoom slider is located in the bottom right corner of you Word window. The default is 100%, but for 24 inch screens I typically bump this percentage to 180%. Click the 100% in that bottom right corner to get the Zoom configuration screen (Figure K) and change the percentage to 180. Or if you are good with the slider you can simply move it to your desired percentage.

Fig. k - Zoom to 180%

Bottom Line

None of the changes I have outlined are absolutely necessary, but for me, making these adjustments saves time, frustration, and headaches. The changes you make may not be the same as mine, but I am willing to bet, whatever changes to defaults you do make, are also made with the desire to save you time, frustration, and headaches.
