TypeAhead Property

In This Topic

Gets or sets a value indicating whether Reflection buffers characters that you type in the terminal window.

Syntax

Visual Basic
C#

'Declaration
 
Property TypeAhead As Boolean

'Usage
 
Dim instance As IIbmTerminal
Dim value As Boolean
 
instance.TypeAhead = value
 
value = instance.TypeAhead

bool TypeAhead {get; set;}

Property Value

When this property is True (the default), characters are buffered and sent to the host as soon as possible. When it is False, characters are not buffered, and anything you type while the host is not ready is lost.

Exceptions

Exception	Description
Attachmate.Reflection.SecuredSettingException	This exception is thrown when you modify a property that was secured via the Permissions Manager or that can only be modified by an Administrator.

Remarks

This setting is relevant to 5250 and 3270 terminal sessions.

If you are working with an AS/400 host, TypeAhead allows you to keep typing when the keyboard is locked (for example, by a HLLAPI application). Reflection does not buffer characters when input is inhibited. If you are working with a 3270 host, TypeAhead allows you to keep typing after you send data to the host. Without TypeAhead, characters you type are ignored until the host is ready for more data (that is, when the X disappears from the Operator Information Area).

The following 3270 functions are processed immediately and are not buffered, even when TypeAhead is True:

Function	Default Keystroke
Alt Cursor	Alt-6
Cursor Select	Ctrl-F3
Next Window	Alt-N
Pan Left	Ctrl-Left arrow
Pan Right	Ctrl-Right arrow
Reset	Esc
Scroll Up	Ctrl-Up arrow
