We are looking at using the WinFormsControlHelpers.h (thank you very
much, Chris Sells and Mark Boulter :) to host some of our WinForms
controls in an old MFC app. It is working very well aside from one
small issue which is tab order.
MFC pays no attention to the TabIndex property (just using the

What is the exact text of the exception that you catch when you execute
the delete operation?

Yes, I should have made this clearer. Of course the presence of code does
have a one-off cost which you will pay when the assembly gets loaded and
when methods get JITted, but as you say this does not affect the size of
each obj
I would use reflection to see if there were any accessible constructors
of foo.bar that took a single integral parameter...benefits being that
this would work for non-COM .net objects as well.

This is true, but the presence of code turns out to be irrelevant. An
object with no data AND no code will also consume memory. Exactly the
same amount of memory will be consumed in either case.
The type header pointer is the same size for all objects - it's just a
pointer! And the sync block in
It gets worse. Look at the following code:
using System;
class Class1
{
static void Main(string[] args)
{
ArgIterator iter = new ArgIterator(Foo(__arglist(1, 2, 3)));
}
static RuntimeArgumentHandle Foo(__arglist)
{
return __arglist;
}
}
This is effectively the same as return

I'd suggest you should use SQLDMO for database management like this. You
can use SQLDMO straight from .NET and it has handy methods for
dropping/creating/attaching etc databases and other sql server

It's hardcoded in the compiler. If you've got the Rotor sources

Every object carries around a vtable pointer (because System.Object has
virtual functions) and a sync block index. So yes, instantiating even an
object with no data will consume memory.

Hi,
I installed a couple of my components in the GAC using the following
command.
gacutil /nologo /if C:\EPM\Bin\BTA.EPM.Agent.dll
and uninstalled using
gacutil /u BTA.EPM.Agent
This worked fine but today I came up with this problem. It says something
about the Windows Installer but I have
The COM platform provided the moniker mechanism to create objects in a certain fashion
and initialize those objects a certain way. This was quite convenient when
representing the object specification as a string.
If I want a user to be able to configure a .net object construction, how would I g
Does anyone know what factors affect the memory size an object will
consume by simply creating a new instance? I know that member-level value-
types will consume memory respective of their data type (Int32 consumes 4
bytes, etc.). What about code? Does a class that contains no member

Thx for the response: I could not see the file you mentioned to unzip from,
so I cannot compare my solution and yours, but I have also played around
over the weekend, and here is my solution: (In my limited test environment,
it seemed to work 100%)
I create a factory type class with the abil
I am trying to create a new appdomain and load an assembly into it using
the AppDomain.Load() method. When I try the following code

domainSetup.ApplicationBase = @"";
domainSetup.ApplicationName = "Component";
It's impossible to tell what you mean by this message. It's possible
that you're saying that Java is 10 times slower than VC, or possibly
that it's 10 times faster. (I'm guessing though that you mean C# is in
the middle.)
Where does the TCP echo server come into this? What are your tests

I'm assuming you tried to attach something to the message, but I
think you can't add attachments in the discussion group messages.
Anyway, I look forward to your example...
