When creating a new class, is it encouraged to always include error
handling routines within your LET and GET procedures? It's seems that
most text books never seem to include much about error handling within
classes. Just hoping to hear some programmer's thoughts on error
handling.

Hi
I am calling .NET components from my Classical ASPs.
For this I strong named my assemblies, then registered them in the resistry
( using RegAsm), and put them in GAC (using GacUtil) .
Everything worked fine and my ASPs were able to call and use them.
The problem comes when my ASP code assigns an ASP object variable to a
property of a class in the assembly like:
oDotNetObject("Name") = Request("Name")

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.

I have read that Exception Handling is expensive performance wise ( other
than Throw ) , but exactly how ?
Please consider the following example ...
////////////////// Code Block 1 //////////////////////////////////
Try
{
for ( ... ){// Code that might throw exception}
}catch(...){}

I often read a recordset (ADO) into a variant array so that the array can
contain text, currency, boolean, etc. VB.Net does not allow variants and the
object type gives errors during conversion from VB6. To complicate matters,
I also like to make the array 2 dimensions so I can put multiple records into
the array. This is a great way to pass recordset info in/out of a
subroutine, but now it does not work.
Any help most apreciated.

Hi all
I've got nearly 2 years experience programming in C and image
processing. Now I have to migrate one of my applications to a MFC
interface. I am having problems with the VARIANT variable. Let's see.
I have been using Matrox Imaging Lybrary (MIL). With this library, I
can load an image and pass this image into a C array using the function
MbufGet() and perform all my calculations using C.

Hello,
I am having trouble upgrading my VB apps to .net. When i started at
my company there was a dll created here in vb6, and i need to use that
dll for many functions that would take too much time to re-create for
the limit that i am given. I have to create a new app in .net, per my

I'm using VC6.
i have a DLL written in VC6 and used by VB6( and VBA Excel),
i use SafeArray as parameter, the array is created(declared), in VB
and C++ fill it.
now i need VC++ to get an array of array of different sizes, and VB
can't know the size of these arrays, so the arrays will be 'created'
in VC.
here the code that i use(and it crashes):

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
