Hi all. I have a problem I have not been able to find a reference
about. I am using VB6 and am only a hobbyist programmer. I have 7
arrays of type MyData. Type MyData has 23 elements. Which array that
is operated on depends on 1 of 7 options Currently if I want to write
to an array I have to do this:
if opt1 then
array1(x).data1= 36
array1(x).data2= 23

We've had a very large A97 app running fine for the last seven years.
I've just converted to SQL Server backend, which is being tested, but
meanwhile the JET based version, running under terminal server, has
suddenly started running very slowly. The network engineer has thrown
up his hands and said "It's Access 97". I've checked out lots of
things including the Oplocks setting and other stuff from this NG, and
I think I've done everything...

Helo all,
I have a standalone unmanaged C++ application that makes a call on another
standalone COM server, which raises an event that should be handled in C#.
I am trying to send: unsigned long, double, BSTR, and VARIANT.
The unsigned long, double, and BSTR (marshalled to System.String) work just
fine and dandy.

Hi
From what I understand, you can pass arrays from classic ASP to .NET using
interop, but you have to change the type of the.NET parameter to object.
This seems to be because classic ASP passes a variant containing an array,
and interop expects a parameter of type object if you are passing a variant
(you are expected to cast it to the correct type in your code). I'd like to
find a way of passing arrays so that you don't need to change...

I'm wondering if anyone can shed some light on this? I'm trying to
enumerate the uninstall registry key (to display installed applications)
with VB.NET and WMI
I'm pretty stuck. When I try to collect the installed software via a
call to EnumKey, I get a type mismatch (the exact erro
is: "System.Runtime.InteropServices.COMException (0x80041005): Typ

I am trying my first VB6 to ,Net upgrade. The app uses the MS Forms 2 ListBox

My original program assigns a column in the list box using:

the line to:
.set_Column(V)

Hello,
I am trying to update my legacy dll to .net. Currently one of the functions in the dll accepts a paramarray of variants, and I need to upgrade that to .net. But in .net it changes the variant type to object. But the dll will still need to be accessed by a VB6 application. This is causing an error when the function tries to get called. It does not recognize the variable type.
Any help would be greatly appreciated.
Thanks,...

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
