In Audition and a couple of others they seem to be connecting to the
running application by connecting to some of it's MSAA Events I guess.
In the Audition script they seem to be using a variable called accObject
as a reference to something in the Running Application. First, where are
they getting the reference and defining the accObject variable value?
The variable name accObj doesn't mean anything itself. I could have used
myFavoriteVariableName. The data that variable contains depends on the
event that called the function.
For example, you'll note around line 266:
ConnectEvent(myMSAAEventSource, "OnObjectFocus", "OnObjectFocus")
That says, in a nutshell, "Watch for MSAA focus events, and when one
happens, call the custom routine OnObjectFocus." I tend to use the name
of the event as the name of my event handler to keep things easy to find.
You can tell from the documentation for the OnObjectFocus event that a
single parameter (an Accessible object) will be passed to the event
handler (i.e. the OnObjectFocus subroutine). In my OnObjectFocus
routine, I chose to name that parameter accObj, which is short (in my
mind) for accessible object. I use that variable name often because it
helps me remember that the data being passed to my event handler is an
Accessible object.
Second, I want to set and change properties in a DataGridView in the
Running Application
That means modify the existing instance of the control
So, how do I get a reference to the control so I can access it's
properties and methods?
You can get a Control object for a window by calling that window's
Control method. The DataGrid objects are not standard controls, so
you're not going to be able to do anything with them through the
Window-Eyes Control object interface. Supported controls are listed in
the documentation as:
CheckBox
ComboBox
EditBox
GroupBox
ListBox
ListView
ProgressBar
PushButton
RadioButton
Static
TabControl
TrackBar
TreeView
UpDown
In VBS I think the Create or GetObject would be used but what about in
Windoweyes?
I do not see anything like that in several GW scripts I looked at.
Both CreateObject and GetObject are used throughout our scripts. Perhaps
more detail about what you're looking for would be helpful.
The closest thing in the Audition Script seems to be a variable they
call accObject.
Where do the define that variable and where do they load it's value with
a CreateObject or GetObject or even just create a new instance with the
New keyword or what?
The accObj parameter discussed above doesn't have anything to do with
GetObject.
I've spent days trying to figure this stuff out, no books, no
documentation other than cryptic object definitions and scripts that
don't seem to follow the VBScript as I have read up on in the MS
manuals.
Here, again, is where more detail would be helpful. What exactly are you
looking for?
Also, I found one of the commands ConnectEvent. Not a command
nor subroutine but a method under the Script Object. But, you would
never know that as there is no object where the method is being applied.
It should be MyScript.ConnectEvent(Whatever)
Or something like that.
The Script object is a root object, just like Application. You can call
ConnectEvent (and other script methods) directly.
Also, the ConnectObject talks about connecting
multiple events, what? Doesn't the ConnectObject Method, if that is what
they want to call it, suppose to, well, connect an Object?
ConnectEvent allows you to hook a single event. ConnectObject allows you
to hook multiple events using a single call.
For example, I could do:
ConnectEvent MSAAEventSource, "OnObjectFocus", "MyFocusRoutine"
ConnectEvent MSAAEventSource, "OnObjectNameChange", "MyNameChangeRoutine"
ConnectEvent MSAAEventSource, "OnObjectStateChange", "MyStateChangeRoutine"
with the corresponding subs:
Sub MyFocusRotine(obj)
End Sub
Sub MyNameChangeRoutine(obj)
End Sub
Sub MyStateChangeRoutine(obj)
End Sub
or, using ConnectObject, I could do:
ConnectObject MSAAEventSource, "myMSAA_"
Sub myMSAA_OnObjectFocus(obj)
End Sub
Sub myMSAA_OnObjectNameChange(obj)
End Sub
Sub myMSAA_OnObjectStateChange(obj)
End Sub
With ConnectObject, you specify a function name prefix, and then you can
access any of the object's events using that prefix plus the event name
(as demonstrated above).
So, anyway, if you know where they define the accObject, where they it's
value and if that is some object running in the Running Application
could you let me know?
As mentioned, accObj is a variable that references the Accessible object
passed through an MSAA event handler.
One more thing, what is an Overlp? From what I learned it was something
on a screen overlapping another item, here it looks like they mean the
Running Application. Is this the case?
An overlap window is typically a window that contains a title bar and
border.
