This can happen if some event causes a function to occur more than once
when the focus changes.
I fixed this once in an app that I was scripting by modifying the
SayObjectTypeAndText function for that application. You will need to
determine just which function is actually being used to speak the
control. I would start by creating a function by that name and
including a saystring or some other statement to speak something so that
you know if this is the function that needs to be changed. If this is
the right function, you will probably hear Jaws speak your string once
or more times each time you press the tab key. If this is the case and
you do hear this double speaking of your string, then you will know what
function to modify.
Next you will need to declare a global variable to contain the name or
whatever information is being spoken when the control gains focus.
I will include below the function that I wrote which I hope will give
you some idea on how to proceed.
The Global variable I declared was called gsFieldName and it was a
string variable.
the following statement will do this.
globals string gsFieldName
The problem I was addressing in this situation was the fact that Jaws
was speaking the name of the field each time I typed any character into
the edit field. therefore I wanted Jaws to speak only when the name of
the field changed. You will see that in the SayobjectTypeAndText
function I checked to see which Dialogue or real window names were being
used and I only called the speakeditFields function for those dialogues.
If these dialogues were not being used, I called the default version of
SayobjectTypeAndText function. This way I make sure that I continue to
get the benefits of the default Jaws functionality when appropriate.
Void Function SayObjectTypeAndText (int id)
var string sName, string sClass, handle hwnd
let sName = GetWindowName (GetRealWindow (GetFocus ()))
let sClass = GetWindowClass (GetFocus ())
if (StringContains (sName, "Search - Formulaire de recherche")
|| StringContains (sName, "Electronic - Électronique")
) then
if (StringContains (sName, "Electronic - Électronique" ) &&
StringContains (sClass, "EDIT")) then
ScheduleFunction ("SpeakEditFields", 1)
RETURN ; get out so that default function is not
performed.
endif
endif
SayObjectTypeAndText (id)
EndFunction
Now here is the SpeakEditFields function.
The looping through window names is specific to my application and
would not normally be necessary. However it will provide an idea of
what can be done to obtain the name of a window. Notice that I used the
StringContains function to determine if the window name was the same.
The StringContains function will return a positive number if the string
is found and will return false or zero if the string is not found. So
in this case I want nothing to happen if the string is found and if the
string is different, I want the name of the field to be spoken and I
want the value of the global variable to be set to the value for the new
name.
I hope I have explained this well enough to give you some ideas for
your scripts.
Void Function SpeakEditFields ()
var string sLabel, handle hwnd, string sName
let hwnd = GetParent (GetFocus ())
let hwnd = GetFirstWindow (hwnd)
while (StringLength (sName)<1)
let sName = GetWindowName (hwnd)
let hwnd = GetNextWindow (hwnd)
endwhile
if (StringContains (gsFieldName, sName)) then ; do nothing
else
let gsFieldName = sName
IndicateControlType (wt_edit, sName, GetWindowText (GetFocus (),
false))
endif
EndFunction

Last lickable problem: Why do all the tutor messages and controls that
have them speak twice when I tab through the pane?
