I have a situation where I have a vector<gcroot<ManagedWrapperClass*> >
whose contents I need to pass to an unmanaged function. Is there a way
to pin all the pointers in the vector for that function? I tried to
copy the vector into another vector with a pinned pointer type, but the
compiler will not allow __pin to be used in a template parameter.
Thanks!

I have two questions:
a) From documentation located at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcmxspec/html/vcManagedExtensionsSpec_7_7.asp,
it says, "Pinning a sub-object defined in a managed object has the effect of
pinning the entire object. For example, if any element of an array is pinned,
then the whole array is also pinned. There are no extensions to the language
for declaring a pinned array. To pin an...

Vs.Net 2003 has recently started hanging when I try to pin the toolbar. The
framework 1.1 service pack 1 has been installed, but I don't know if this
started happening after I installed it. I've certainly only recently noticed
the problem, and I believe (but can't be certain) that it's since the
service pack was put on. The only way out of it seems to be killing the...

Hi all,
I want to understand more about how the pinvoke pinning process works.
I'm writing some code that calls DeviceIoControl.
DeviceIoControl provides a generic interface to device drivers.
Its signature is deliberately open-ended so that it can be highly generic.
Refer SDK for more.

Hi,
I have a rather interesting problem. I have a unmanged c++ class
which needs to communicate information to managed c++ via callbacks,
with a layer of c# on top of the managed c++ ultimatley retreiving the
data. Presently all of the c++ code is still in .NET 1.1, so we're
using a _nogc bridge class wrapped in a _gc c++ class in order to
facilitate this interop.
But we've converted everything not c++ to .NET 2.0 and would love to

Hi all,
This is my first time trying to creaet and use a custome Web Control in a
Web Site project in ASP.NET 2.0 with VS 2005 and VB. I created the control
in a separate Web Control Library project. The original code for that
control was written in VS 2003 for .NET 1.1.
I created a Web Project and pulled the VB module into the project. I
compared the syntax to the VB template classs that was built and it looked
very similar. I then...

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

Overview:
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,...
