Issue

Programmers may have a need to send keystrokes to an active PASSPORT session from an external application.

Solution

Beginning in version 2002 of PASSPORT, the terminal emulation contains a new object layer (PASSOBJ.DLL) that allows programmers to create a COM object that may be used to send keystrokes to an active PASSPORT session.

Example

Below is sample Visual Basic code that sends a text string to a specific PASSPORT session, followed by the ENTER key:

Sub Main()

Set objPassport = CreateObject("PASSPORT.System")

num =objPassport.Sessions.Count

if num > 0 then

for i=1 to num

if objPassport.Sessions.Item(i) = "MySession" then

set ActiveSess = objPassport.Sessions.Item(i)

end if

ActiveSess.Activate

ActiveSess.Screen.WaitHostQuiet(gkHostSettleTime)

ActiveSess.Screen.SendKeys"MyText<ENTER>"

End Sub
