Consider a scenario in which Alice wants to send the message meet me at central park to Bob. Alice does not want other people to understand the message that she is sending to Bob. She encrypts the message using a substitution cipher algorithm (which we will discuss shortly) and sends the string phhw ph dw fhqwudo sdun to Bob. After briefly introducing some terminology, we will describe how the encrypted message was obtained. The original message, meet me at central park, is called the plaintext. The encrypted message is called the ciphertext. When messages are encrypted with a substitution cipher, each letter in the plaintext is replaced with another letter to produce the ciphertext. A key is used to determine which letter should appear in the ciphertext, given a letter in the plaintext. In our example, the key we used is 3. For each letter in the plaintext, we replaced it with the letter that appears 3 letters later in alphabetic order. So, a is replaced by d, b is replaced by e, and so on. If one of the last few letters in the alphabet appears in the plaintext, such as x, y, or z, we wrap around to the beginning of the alphabet if necessary to determine the letter to appear in the ciphertext. For instance, if x appears in the plaintext, then a would appear in the corresponding ciphertext. The correspondence is shown here: Plaintext: abcdefghijklmnopqrstuvwxyz Ciphertext: defghijklmnopqrstuvwxyzabc how to get input from barcode reader in java Barcode Scanner implementation on Java - Stack Overflow

The GtkFileChooserButton widget is an implementation of the functionality provided by the GtkFileChooser interface. This means that, while the button is not derived from GtkFileChooser, it can be treated as a file chooser if you cast it with GTK_FILE_CHOOSER(). You will notice that quite a few of the functions in Listing 4-10 utilize functions provided by GtkFileChooser. In Listing 4-10, gtk_file_chooser_set_current_folder() was used to set the current folder of each file chooser button to the user s home directory. The contents of this folder will be shown when the user initially clicks a file chooser button unless it is changed through some other means. This function will return TRUE if the folder was successfully changed. gboolean gtk_file_chooser_set_current_folder (GtkFileChooser *chooser, const gchar *filename); The g_get_home_dir() function is a utility function provided by GLib that returns the current user s home directory. As with most features in GLib, this function is cross platform. This brings up a useful characteristic of the file chooser interface; it can be used to browse many types of file structures, whether it is on a UNIX or Windows machine. This is especially useful if you want your application to be compiled for multiple operating systems. Since the file chooser button only allows one file to be selected at a time, you can use gtk_file_chooser_get_filename() to retrieve the currently selected file or folder, depending on the type of file chooser button. If no file is selected, this function will return NULL. The returned string should be freed with g_free() when you are finished with it. gchar* gtk_file_chooser_get_filename (GtkFileChooser *chooser); At this point, you have enough information about the GtkFileChooser interface to implement file chooser buttons. GtkFileChooser will be covered in more depth in the next chapter when you learn about the GtkFileChooserDialog widget. barcode scanner javascript html5 Barcode API Overview | Mobile Vision | Google Developers

For example, in Listing 4-10, only PNG, JPG, and GIF files could be viewed and chosen by the user when the Image Files filter was selected. File filters are created with gtk_file_filter_new(). Therefore, you need to use gtk_file_filter_set_name() to set a displayed name for the filter type. If you provide more than one filter, this name will allow the user to switch between them. GtkFileFilter* gtk_file_filter_new (); void gtk_file_filter_set_name (GtkFileFilter *filter, const gchar *name); Lastly, for a filter to be complete you need to add types of files to show. The standard way of doing this is with gtk_file_filter_add_pattern() as shown in the following code snippet. This function allows you to specify a format for the filenames that are to be shown. Usually identifying file extensions that should be shown does this. You can use the asterisk character as a wildcard for any type of filtering function. void gtk_file_filter_add_pattern (GtkFileFilter *filter, const gchar *pattern); java barcode scanner example Downloads Java Barcode Scanner Apps Download - java -ware.net
