Hello,
I'm seeing strange behavior experimenting with calling .NET. If I
create a project in .NET 2k3 and select 'interop assembly' it will
create the CCW for me, correct?
I created a class library with this class in it:
Public Class TestCCW
Public Sub Stream(ByVal filename As String)
MsgBox("filenam e is '" & filename & "'")
End Sub
Public Sub Stream2(ByVal filename As String, ByVal tmp As
String)
MsgBox("filenam e is '" & filename & "' tmp is '" & tmp &
"'")
End Sub
Public Sub Stream3(ByRef filename As String)
MsgBox("filenam e is '" & filename & "' ")
End Sub
Public Sub Stream4(ByRef filename As String, ByRef tmp As
String)
MsgBox("filenam e is '" & filename & "' tmp is '" & tmp &
"'")
End Sub
End Class
I build it successfully, and in Access 2k2 I make the following VBA
calls (tied to a button click):
Private Sub Command1_Click( )
Dim tmp As XSDLib3.DaoSdr
Set tmp = New XSDLib3.DaoSdr
Dim rs As DAO.Recordset
Set rs = Me.Recordset
tmp.Stream ("foo")
' Compile error: Syntax error
'tmp.Stream2("s tream2","bar")
tmp.Stream3 ("stream3")
' Compile error: Syntax error
'tmp.Stream4("s tream4","bar")
Set tmp = Nothing
End Sub
I thought at first it might be a ByRef vs. ByVal problem, hence Stream
vs. Stream3 (which work succesffully). But that wasn't the case
Can anybody advise me as to why stream2 and stream4 fail with compile
errors?
Thanks 1 1799

This is a longshot, but since Stream, Stream2, Stream3 and Stream4 are
subs, you need to call them without using parentheses:
tmp.Stream "foo"
tmp.Stream2 "stream2", "bar"
tmp.Stream3 "stream3"
tmp.Stream4 "stream4", "bar"
Not sure if this is the problem, but it's worth checking.

Up until now I have had no problems translating some of the tamer functions that they currently have in VBA, however...

Hi,
I have a COM method that is called from VBA. This COM method in turn
calls CoCreateInstance on a class that is a .NET class with a COM
wrapper around it. This all works fine. However, when I kick off
that VBA routine from a .NET class within an assembly, I get a class
not registered error. When CoCreateInstance is called on that COM
visible .Net class a second time, then there is a security violation.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
