Asalam-o-Alaikum,
I study Win32 programming in my special semester.The
Win32 programming is implemented by Visual Studio C++ 6.0. Here we
study about the languages, locals and key board layouts. In Win32
there are API which are use to select the language for input and out
the data. Below the study material regarding the loading and changing
the keyboard layout.
"A language is a natural language, such as English, French, and
Japanese. A sublanguage is a variant of a natural language that is
spoken in a specific geographical region, such as the English
sublanguages spoken in England and the United States. Applications use
values, called language identifiers, to uniquely identify languages
and sublanguages.
Applications typically use locales to set the language in which input
and output is processed. Setting the locale for the keyboard, for
example, affects the character values generated by the keyboard.
Setting the locale for the display or printer affects the glyphs
displayed or printed. Applications set the locale for a keyboard by
loading and using keyboard layouts. They set the locale for a display
or printer by selecting a font that supports the specified locale.
A keyboard layout not only specifies the physical position of the keys
on the keyboard but also determines the character values generated by
pressing those keys. Each layout identifies the current input language
and determines which character values are generated by which keys and
key combinations.
Every keyboard layout has a corresponding handle that identifies the
layout and language. The low word of the handle is a language
identifier. The high word is a device handle specifying the physical
layout, or is zero indicating a default physical layout. The user can
associate any input language with a physical layout. For example, an
English-speaking user who very occasionally works in French can set
the input language of the keyboard to French without changing the
physical layout of the keyboard. This means the user can enter text in
French using the familiar English layout.
Applications are generally not expected to manipulate input languages
directly. Instead, the user sets up language and layout combinations,
and then switches among them. When the user clicks into text marked
with a different language, the application calls the
ActivateKeyboardLayout function to activate the user's default layout
for that language. If the user edits text in a language which is not
in the active list, the application can call the LoadKeyboardLayout
function with the language to get a layout based on that language.
The ActivateKeyboardLayout function sets the input language for the
current task. The hkl parameter can be either the handle to the
keyboard layout or a zero-extended language identifier. Keyboard
layout handles can be obtained from the LoadKeyboardLayout or
GetKeyboardLayoutList function. The HKL_NEXT and HKL_PREV values can
also be used to select the next or previous keyboard.
The GetKeyboardLayoutName function retrieves the name of the active
keyboard layout for the calling thread. If an application creates the
active layout using the LoadKeyboardLayout function,
GetKeyboardLayoutName retrieves the same string used to create the
layout. Otherwise, the string is the primary language identifier
corresponding to the locale of the active layout. This means the
function may not necessarily differentiate among different layouts
with the same primary language so, it cannot return specific
information about the input language. The GetKeyboardLayout function,
however, can be used to determine the input language.
The LoadKeyboardLayout function loads a keyboard layout and makes the
layout available to the user. Applications can make the layout
immediately active for the current thread by using the KLF_ACTIVATE
value. An application can use the KLF_REORDER value to reorder the
layouts without also specifying the KLF_ACTIVATE value. Applications
should always use the KLF_SUBSTITUTE_OK value when loading keyboard
layouts to ensure that the user's preference, if any, is selected.
For multilingual support, the LoadKeyboardLayout function provides the
KLF_REPLACELANG and KLF_NOTELLSHELL flags. The KLF_REPLACELANG flag
directs the function to replace an existing keyboard layout without
changing the language. Attempting to replace an existing layout using
the same language identifier but without specifying KLF_REPLACELANG is
an error. The KLF_NOTELLSHELL flag prevents the function from
notifying the shell when a keyboard layout is added or replaced. This
is useful for applications that add multiple layouts in a consecutive
series of calls. This flag should be used in all but the last call.
The UnloadKeyboardLayout function is restricted in that it cannot
unload the system default input language. This ensures that the user
always has one layout available for enter text using the same
character set as used by the shell and file system."
