I have been banging my head against the wall for a while now, and can't
seem to id the problem. I've been through a ton of posts and the code
doesn't seem any different. Can anybody see it?
When I call to GetTokenInformation I receive a buffer size (see
//HERE... comment in code), but when I let the code continue, asp.net
just sits there returning nothing, apparently on the
Marshal.AllocHGlobal call.
Here's the library function:

Hello,
Regarding Marshal.AllocHGlobal versus Marshal.AllocCoTaskMem Does anyone
know the circumstances in which one should use one over the other?

The following almost works.
The problem is Marshal.PtrToStringAuto seems to terminate at the first null
so I don't get the full string.
Any suggestions on how to fix this?
Or how to improve the code?
Thanks
PS I added the +1 because as I understand the GetLogicalDriveStrings doc

I need to call into a C++ DLL from my C# code.
The function is expecting a void pointer to an unsigned short.
Which would be more correct?
UInt16 wRegData;
IntPtr p = Marshal.AllocHGlobal(Marshal.SizeOf(wRegData));
Marshal.StructureToPtr(wRegData, p, false);

When using Marshal to copy data from a byte array to the structure
below, only the first byte of the "other" array is getting copied from
the original byte array. What do I need to specify to get
Marshal.PtrToStructure to copy the all the data into the "other"
array?

I have operation within a class that marshals the data into a byte
array. Below are three different ways that work. Are there any
downsides to using one over the the other?
public virtual byte ToRaw1()
{
byte byteArray = new byte;
IntPtr pointer = Marshal.AllocHGlobal(Size);
Marshal.StructureToPtr(this, pointer, false);
Marshal.Copy(pointer, byteArray, 0, Size);

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
