I have read several interesting posts on passing structures to C dlls, but none seem to cover the following case. The structure (as seen in C) is as follows:
typedef struct tag_scanparm
{
short cmd;
short fdc;

short boxcar;
short average;
short chan_ena;

When I declare an array as double(,) then try to use it I get an error:
"Object reference not set to an instance of an object."
I have found that I can redim the array and all is well. Is my approach

format for an array.

I am having trouble figuring out how to declare a pointer to an array
of structures and initializing the pointer with a value. I've looked

sensible, but it didn't work right. Here is a simple example of what
I'm trying to accomplish:

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,...
