Hello Guys,

 I just wanted to tell you all that you must be careful when buying a domain from Yahoo.com. I was using a Yahoo domain which had a billing amount of $9.95. This year (third year) Yahoo automatically increased the billing amount to $34.95 without giving any prior information and even billed the amount. I checked the help service which tells me that I can cancel the service but I will not get any refund at all. Calling the Yahoo customer care is not an option and no email id is provided for the customers to get in touch with Yahoo. If Yahoo has only US numbers and no email ids, why in the name of God should they bill to non US citizen??

I am really disappointed from being cheated in such a fashion from a company which talks about morales and honesty. I am using GoDaddy.com for 2 of my other domains and never had any such issue. It also gives me a simple option not to get auto billed without prior information, a option which I failed to find with Yahoo.com.

 The picture of the billing is attached for all of you to see. I hope nobody else gets cheated in such a way.

Commands in WPF can be defined and maintained in a static class. The commands need to be bind with the window whose controls use them. To bind the commands, events CanExecute and Executed events need to defined in the window itself. But most of the times, people want all their commands and related CanExecute and Executed events in one single static class which makes it easier to maintain the program logic from one central place. The purpose of this article which I posted on codeproject is to tell you how to enable this facility.

Code breaking changes:

Formula system does not work the way it used to, so the previous code might break. For backward compatibility, I have included a static class FormulaHelper which can be used with the previous code. Just replace the previous code in the following way:

   1:  cell.Value = new Formula("Sum", new Range(sheet[3, 3], sheet[6, 3]));

to

   1:  cell.Value = FormulaHelper.Formula("Sum", 

   2:       new Range(sheet[3, 3], sheet[6, 3]));

Changes:

• New Formula system implemented.

• RowSpan and ColumnSpan properties added to cell.

• Small error in named range rename fixed.

• Freeze column won't work if freeze row is set. Fixed.

• Style was not saved in Column export. Fixed.

• Assembly file contained wrong information about this library. Fixed.

• Workbook export can throw a NullReferenceException when new XmlWriter is created. Fixed.

• Documented IStyle interfaces.
