returns A Unicode character that corresponds to the code specified.
GetCharacterCode(character)
Given a Unicode character, gets the corresponding character code.
character The character whose code is requested.
returns A Unicode based code that corresponds to the character specified.
GetIndexOf(text,subText)
Finds the position where a sub-text appears in the specified text.
text The text to search in.
subText The text to search for.
returns The position at which the sub-text appears in the specified text. If the text doesn't appear, it returns 0.
GetLength(text)
Gets the length of the given text.
text The text whose length is needed.
returns The length of the given text.
GetSubText(text,start,length)
Gets a sub-text from the given text.

length Specifies the length of the sub text.
returns The requested sub-text
GetSubTextToEnd(text,start)
Gets a sub-text from the given text from a specified position to the end.
text The text to derive the sub-text from.
start Specifies where to start from.
returns The requested sub-text.
IsSubText(text,subText)
Gets whether or not a given subText is a subset of the larger text.
text The larger text within which the sub-text will be searched.
subText The sub-text to search for.
returns True if the subtext was found within the given text.
StartsWith(text,subText)
Gets whether or not a given text starts with the specified subText.
text The larger text to search within.
subText The sub-text to search for.
returns True if the subtext was found at the start of the given text.

BackgroundColor
Gets or sets the background color of the text to be output in the text window.
Clear()
Clears the TextWindow.
CursorLeft
Gets or sets the cursor's column position on the text window.
CursorTop
Gets or sets the cursor's row position on the text window.
ForegroundColor
Gets or sets the foreground color of the text to be output in the text window.
Hide()
Hides the text window.
Left
Gets or sets the Left position of the Text Window.
Pause()
Waits for user input before returning.
PauseIfVisible()
Waits for user input only when the TextWindow is already open.
PauseWithoutMessage()
Waits for user input before returning.
Read()
Reads a line of text from the text window. This function will not return until the user hits ENTER.
returns The text that was read from the text window
ReadKey()
Reads a single character from the text window.
returns The character that was read from the text window.
ReadNumber()
Reads a number from the text window. This function will not return until the user hits ENTER.
returns The number that was read from the text window
Show()
Shows the Text window to enable interactions with it.
Title
Gets or sets the Title for the text window.
Top
Gets or sets the Top position of the Text Window.
VerifyAccess()
Verifies if the access to text Window has been made yet
Write(data)
Writes text or number to the text window. Unlike WriteLine, this will not append a new line character, which means, anything written to the text window after this call will be on the same line.
data The text or number to write to the text window
WriteLine(data)
Writes text or number to the text window. A new line character will be appended to the output, so that the next time something is written to the text window, it will go in a new line.
data The text or number to write to the text window.
Timer
The Timer object provides an easy way for doing something repeatedly with a constant interval between.
