Update WCF Service Site References

If you have a problem updating dll files in the bin folder of your Web Site deployment project, the following method may work: delete all dll files in your bin folder, and then add a reference to you Service project. All the other required dll files will be added automatically.

Regex for Month Number

This is the regular expressions pattern I use to test whether string characters represent a month number (from 01 to 12):

(0[1-9]|1[0-2])

The expression part inside the brackets is broken into 2 possible parts divided by a vertical bar (or pipe symbol): 0[1-9] or 1[0-2].

If a string matches any of the 2 parts it is true.

The first one says that the 2-character string has to start with 0 and end with any number in the range from 1 to 9, e.g. 01, 02, 09

The second part matches any 2-character string that starts with 1 and ends with 0, 1 or 2, i.e. 10, 11, or 12

Delete Contents of IsolatedStorageFile

The easiest way to delete contents of an IsolatedStorageFile is to open it in the Truncate mode:

IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForAssembly();

IsolatedStorageFileStream isoFile = new IsolatedStorageFileStream(myFileName, FileMode.Truncate, isoStore);

According to the MSDN , if a file is opened in the Truncate mode its size should be 0 bytes.
