The .NET AutoPostBack feature may not work for all users

The TextBox, CheckBox, RadioButton, and similar controls for ASP .NET Web Forms expose a property called AutoPostBack. If set to True, then any change to the state of the control triggers a postback to the server for some kind of programmatic action. This is all well and good, except for the fact that this functionality is implemented in client-side JavaScript. If users have disabled client-side script from executing, your code will fail unexpectedly. It's therefore not a particularly good idea to rely on this feature unless you warn your users not to disable the exëcutíon of client-side script.

Have you ever wanted to create a Microsoft Outlook task to remind you to do something with an Excel workbook? You could switch to Outlook, open a task form, and create the task item. However, there’s an easier way to create a task from Excel. When you're ready to create the task item, make sure that Outlook and Excel are both open.

A better way to create a Task from an email message (Outlook 2003/2007)

If you need to create a task and already have the relevant information in an email message, use it to your advantage. Just drag the email message from the Message list to the Tasks icon in the Navigation Pane. A new Task form launches with a subject line and the body of the email message in the message area of the Task form. This is all well and good, but where’s the attachment? This method won’t include any attachments from the e-mail message in the Task form, but here’s an easy way to get around that.

Move the pattern - but not the shape (Illustrator CS)

When you apply patterns from the Swatches palette, you'll notice they always apply to graphics in the same way, which can occasionally be problematic. However, you don't have to accept it. You can manipulate the pattern without affecting the shape it's in by pressing the tilde key (~) as you use the Rotate tool, Reflect tool, Scale tool, or Shear tool. Distorting the pattern can make quite a difference in appearance. This trick is especially useful when you're working on a group of objects that all have the same pattern fill. In this case, you can tweak the pattern in each shape just a little bit to keep the patterns from lining up perfectly and inadvertently flattening out the form.

Stop users from copying the text in your Access fields (2003/2007)

As you know, you can set a form field's Locked property to Yes to prevent users from changing the underlying data. However, users are still able to select and copy data from the field, and you may not always want this to be the case. The solution is to also set the field's Enabled property to No. Ordinarily, setting the Enabled property in Access this way causes the field and its associated label to be difficult to read. However, when you set the Enabled property to No and the Locked property to Yes, the fields and labels look exactly as they do when they're enabled for normal entry. The difference is that users will be unable to select or copy any of the displayed data.
