[RESOLVED] Issue with tooltip class

[AdorablePlum]

Hi all,

I'm trying twinbasic and have everything declared and the app loads and runs, which is great.

There is a problem though with a form that contains a combobox of suppliers. This combo uses a class to create a tooltip capable of showing multiple lines and is used to show the supplier's address.

When the form loads the first time it all works, but subsequent loads give the error Run-time error 91 (0000005B) Object variable or With bock variable not set.
This is in the Load event

    Set mclsToolTip = New clsToolTip
    With mclsToolTip
        Call .Create(Me)
        .MaxTipWidth = 240
        .DelayTime(ttDelayShow) = 20000
        Call .AddTool(cmbSupplier)
    End With

The error occurs when setting the property to anything

 mclsToolTip.ToolText(cmbSupplier) = "No address"

The unload event

    Private Sub Form_Unload(Cancel As Integer)
    On Error Resume Next
    Call mclsToolTip.RemoveTool(cmbSupplier)
    Set mclsToolTip = Nothing
    End Sub

mclsTooTip is quite long, so I haven't posted it, but I can do if useful.

Could you provide a small example project to demonstrate the issue? Cleanup when unloading/reloading a form is generally a lot better than it used to be, but there could certainly still be some edge cases.

I set one up, but annoyingly the error didn't occur there. I seem to be able to get round it by checking whether mclsToolTip is nothing and if so reinitialising it.

BTW, I forgot to mention that ToolTipText in twinBASIC supports multi-line text (both in IDE and at runtime)
