Is a structure containing an incomplete array as its last element (per
paragraph 2 of section 6.7.2.1 of ISO/IEC 9899:1999 (E)) itself an
incomplete type? That appears to be indicated by paragraph 22 of
section 6.2.5. If so, that seems to make it difficult to allocate such
structures, because sizeof() is not allowed on incomplete types
(paragraph 1 of section 6.5.3.4).
For instance, I've routinely done things like this:
struct foo {...

Hi
I am new to C# and am rewritting some C++ code. I want to send a byte array over a serial port. The elements of the byte array are really a structure I have populated. My question is, how do I do this in C# - that is, I want to declare a byte array, assign a structure to it, and then be able to populate the structure's fields, then use the byte array
Thank you
Joe

Well, as a matter of fact I_HAD_MISSED a basic thing or two, anyway,
although Ollie's answer makes perfectly sense when dealing with
classes, it doesn't seem to me to apply as well if you have to
instantiate an array of structures; consider the following useless
code :
using System;
struct MyPointS

I have created a structure with five fields. I then create an array of this
type of structure and place the structure into an array element. Say index
one. I want to assign a value to field3 of the structure inside the array.
When I try this, an error about late assignment appears. Is it possible to
assign a value to a structure field that is in an array?
I'm currently getting around the problem by creating a new structure, assign...

What are the ramifications if I were to instantiate an object tens of
thousands of times and add them to an array? Or hundreds of thousands of
times? Do you know if the act of instantiating a class takes a lot of
storage or other resources? Would it be a severe performance penalty?

If I have a structure like;
Public Structure myStructureDef
Public b() as Byte
Public t as String
End Structure
If I pass this structure, will the values in the array b be stored on the
stack or will just a pointer to the array be stored on the stack? I am
trying to decide whether to use Structures or Pointers. I know that M'soft

Hi,
I'm upgrading a VB6 app to VB.net and I'm having a problem with a call to a
function provided in a DLL.
The function takes the address of a structure which it will fill in with
values.
I get an error:

Hi Willy,
Thank you very much for your work.
C++ code doesnot make any serialization.
So at runtime C# code gives an serialization error at
"msg_file_s sa = (msg_file_s) bf.Deserialize(ms);"
I thought that it is very hard to memory map structure array.
I need both read and write memory mapped file at both side of C# and C++.

So I need to talk to a devices that expects all of the bits and bytes I sent
it to be in specific places (not yet 100% defined).
I wanted to create a structure/class with all of the data in it and then
convert that to a byte array, pass it to the device, then get a reply and
then convert that to a structure.
I'm having issues with making sure what I've coded is correct. Cant figure
out how to define an array in structure that is a...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...
