WaitForHostUpdate

Wait for the host to send new screen data. Not useful for VT emulation, which is character based rather than screen based.


Syntax

FlexScreen.WaitForHostUpdate([WaitMSec])


Parameters


[WaitMSec]

Integer, input, optional



Number of milliseconds before the wait method will timeout.


Remarks

If the optional WaitMSec parameter is specified, it will be used as the maximum wait time before a timeout error occurs. If unspecified, FlexScreen.WaitTimeoutMSec will be used instead.


When a timeout occurs, a run time error will be generated and the macro will stop unless On Error Resume Next is in effect, in which case, WaitForHostUpdate will return a false value.


Example

Sub Main()

  Ok = FlexScreen.WaitForHostUpdate()

  Ok = FlexScreen.SendKeys("MyUserID")

  Ok = FlexScreen.SendKeys(FlexKey.ENTER)

End Sub
