v193 can't match event with handler

[dmrvb]

v193 feels like another huge leap forwards. Thankyou. Is it helpful to report bugs now or is there another release in progress?

I see lots of "unable to match this handler to its event member"
some of the events causing this are:
SStab_click
SStab_mousedown
SStab_mousemove
updown_mousemove
toolbar_mousedown
plus others

Also a gentle reminder that Zorder is still not implemented, my Problems pane is full of yellow warnings. 😄

Desktop (please complete the following information):

• OS: [e.g. Windows 11]
• twinBASIC compiler version [193]

Interesting. VB6 doesn't care if there is a mismatch of ByVal/ByRef specifiers for event handlers, so for example SSTab Click is actually defined in the type library as Private Sub SSTab1_Click(ByVal PreviousTab As Integer) but VBx allows, and defaults to Private Sub SSTab1_Click(PreviousTab As Integer). twinBASIC currently fails to match them up as it sees them as incompatible signatures.

Btw, this is not allowed on (early-bound) classes in VB6 and bombs with

---------------------------
Microsoft Visual Basic
---------------------------
Compile error:

Procedure declaration does not match description of event or procedure having the same name
---------------------------
OK   Help   
---------------------------

Sample code:

'--- Class1
Option Explicit

Event Click(ByVal PreviousTab As Integer)

'--- Form1
Option Explicit

Private WithEvents m_oInstance As Class1

Private Sub m_oInstance_Click(PreviousTab As Integer) '<---- does not compile
    '
End Sub

For user-controls the IDE prepares some proxies/wrappers so all sited controls are actually called late-bound through these generated wrappers and some of their events are with changed signatures (pixels<->twips conversions) and new "extender" events are added in the process.

Thanks @wqweto. I have put a fix for this in the next release which only applies to dispinterface source interfaces, so that should match. However, I will check this example you gave before release.

[WaynePhillipsEA]

Fixed in BETA 194, thanks!

[dmrvb]

reOpened
This error is still present in v195 (I have not looked at v194)

[dmrvb]

errors also present in 194

[WaynePhillipsEA]

Hmm, certainly SSTab_Click looks fixed here...

Ah OK, SSTab_MouseDown / SSTab_MouseMove etc are still broken. I'll get them fixed tomorrow.

[dmrvb]

Listbox Itemcheck
ListView mousedown
updown mousedown mouseup
toolbar mousedown
SStab mousedown mousemove mouseup
and just maybe a couple more.
I still struggle to navigate through a big list in the problems pane, up down keyboard keys don't work so doing it on the scrollbar which is not ideal but sort of ok with the mousewheel.

[WaynePhillipsEA]

These should be fixed in BETA 196. Let me know if you find any that are still not correct. Thanks

[dmrvb]

Listbox Itemcheck.
I will go through some other projects and look for any more but probably not till tomorrow.

[WaynePhillipsEA]

What ListBox are we talking about here? The builtin one?

[dmrvb]

I think so, or it could be a ListView. I will look now and can't find any others

[dmrvb]

Yes, its the built in listbox.

[dmrvb]

I have a big real world outside project on today so no more software input till very late evening or tomorrow

[WaynePhillipsEA]

No problem, and thanks for the info

[dmrvb]

Issue still present in v197.
in VB6 the event is List1_ItemCheck(Item As Integer)
in tB its (item as long).
This causes imported VB6 code to generate the error.
Changing to (Item as Long) fixes it.
I am happy to do this but to get full VB6 compatibility I assume it need sorting out?

[WaynePhillipsEA]

Yeah sorry I didn't get chance to look at that today. Will fix tomorrow, cheers.

[WaynePhillipsEA]

Fixed in BETA 198. Thanks!
