Hi Again Chip,
Where can I find the list of event numbers?
I see a partial list but some event numbers are not there.
I decided while testing to look at event numbers and there is a sequence of
several numbers coming up.
Numbers:
100, 101, and 121. I think there was even a 177 in this list once in a
while, but seem to not find any list of values corresponding to those last 2
numbers.
I believe the changed event is 101 but 121 I seem to not be able to find.
So having a complete list of dialog events by value would be nice. I looked at
the Microsoft web site and sure enough it gave names and no values.

Bruce,
I'm still confused as to what you're problem is.
Class # 31 shows how to deal with detecting when a listview selected item
has changed.

Hi Chip,
My mistake, I am playing with the ListView and it has less features than
the ListBox and tried to mention that. I also had no time to test it out and
that makes it more confusing.
For in the ListBox you have everything for setting and getting items but
no columns which I wanted at first but may not use in the future.
At least Jeff has an example he can use but I did try to stress that all
the features he needed did exist in the ListBox but not the ListView.
For when EventInfo is only given it defaults to the control and not it's
items in some case, for there is just no control for a selected item; it
says no object, and noticed it went to the control level instead.
Buttons are nice but as I had stated, the keydown event and keyup even
can be used to compensate for control loss by setting and resetting a flag.
Hopefully Jeff can get his app running using the example and yes, having
all the flags set for an app such as the Explicit is very important to
reduce debug time.

Hi Jeff,
I'm sorry to keep disagreeing with Bruce, but I did take your example, made
several corrections, and it works just as expected.
You have several places where your names in the vbs don't match the names in
the xml, and you have a variable (or two) which aren't initialized (I think
sButton was one of them). It might help if you added "option explicit" at
the top of the vbs.
Anyway, below is a modified version of your vbs example which speaks some
extra text each time the selected listbox item changes. First yu'll hear We
read the new listbox item, then you'll hear my modified example speak the
same line with some added text at the beginning so you can tell it apart
from what WE is speaking.
Aside from correcting variable names, all I did was to add a test for the
listboxSelectionChange event(and as Bruce pointed out), you do have to
initialize it to start with, so that it will work the very first time;
otherwise, it won't start working until the second time.
option explicit
Dialog "testlist.xml", "Dialoglistbox", "DialogEventHandler"
Function DialogEventHandler(dObj, dEvent, dId, dControl)
Dim Result : Result = ""
If dEvent = dialogCreated Then
dObj.Control("lst").Width = 800
BuildList dObj
End If
DialogEventHandler = False
Select Case dEvent
' Process dialog events
case ListboxSelectionChange
DialogEventHandler = True
queue "SaySelectedItem", dObj.control("lst").text
Case dialogCreated
DialogEventHandler = True
Case buttonClicked
If dId = "btnCancel" Then
dObj.Close
DialogEventHandler = True
End If
If dId = "BtnOk" Then
Result = dObj.Control("lst").Text
queue "SaySelectedItem", Result
DialogEventHandler = True
End If
End Select
End Function
Function BuildList(dObj)
dObj.Control("lst").Add "This is the first line in the listBox!"
dObj.Control("lst").Add "Here is the second line."
dObj.Control("lst").Add "Here is the third and longest line in the listbox!"
dObj.Control("lst").FocusedIndex = 1
End Function
Sub SaySelectedItem(Result)
Speak "The item you selected was " & VbCrLf & Result
End Sub
Hth,
Chip

I was unable to get any info while still in the list. I found another way
to do what I wanted.
I added an extra button, made it the default button with enter as its
shortcut, and by pressing enter while still in the list, I can get extra
information. That's not exactly what I wanted, but it's close.
Below is a .vbs and a .xml file showing a simple listbox with 2 buttons.
The files are nameed
DialogListBoxFromScript.vbs
DialogListBoxFromScript.xml
If anybody wants to try to add something to the select case section to
automatically speak additional information when you are just up or down
arrowing through the list, I would certainly appreciate knowing how to do
this.
thanks again,
Jeff Weiss

Jeff,
I don't see that you're initializing the variable Temp anywhere, and I also
don't see that you are setting the focusedIndex property of the listbox
anywhere (which is usually done when you add items to the listbox; you
usually set it to 1 when you add your listbox items).
Take out the line:
If fObj("lst").FocusedIndex <> Temp Then
And you should then hear something spoken each time your listbox item is
changed.

Subject: Re: listbox change
Thank you for all of the suggestions.
This is indeed my own xml listbox dialog and I can get the button to work
but not the listbox change to register where I can do something when it
changes.
The list works fine and displays 12 spelling words.
Here is the function:
Function DialogEventHandler3(fObj, fEvent, fId, fControl)
DialogEventHandler3 = False
Dim Result : Result = ""
fObj.Control("lst").Width = 200
If fEvent = dialogCreated Then
BuildList fObj, Result
End If
DialogEventHandler3 = False
Select Case fId
Case fId = "lst"
If fEvent = listboxSelectionChange Then
If fObj("lst").FocusedIndex <> Temp Then
Temp = fObj.Control("lst").FocusedIndex
Result = fObj.Control("lst").Text
Speak Result
Speak Temp
Speak "this is a test."
Result = ""
Exit Function
End If
End If
Case "button_MainMenu"
If fEvent = buttonClicked Then
Speak ""
Sleep 200
Speak "Returning to Main Menu"
Sleep 200
fObj.Control("lst").Clear
fObj.Close
DialogEventHandler3 = True
Exit Function
End If
Case Else
If fEvent = dialogCreated Then
DialogEventHandler3 = True
Exit Function
End If
End Select
End Function
I must be missing something here. Please let me know what I am missing
here.
thanks
