I thought .NET was supposed to make things easier, if anything, than unmanaged code.
-
it's mixed mode, as I understand it. Managed *and* unmanaged in the same PE. So it's not simply a .NET assembly but an assembly with a bag on the side of unmanaged code. I'm certain this was true when it was introduced. It probably still is. also i think there's still marshalling going on with managed->unmanaged calls in C++/CLI it might be more efficient than the standard marshalling though, but it's still marshalling.
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

yeah thanks. Though what zebra006 (sp?) showed me was more what I was after. Either way, it gives me a starting point.

I said they don't work how they are supposed to. How they were designed was to map files to a process address space so you could do pointer ops to read and write files. That is not doable under .NET. Sorry I've just explained this a lot. If you've used memory mapped files in unmanaged code then you know what i'm talking about. Otherwise you might never. I don't know. You cannot do var foo = new int[100000]; //backed by file. That's how it's supposed to work. It can't under .NET

lol yes there is. You didn't read anything I said. As I said before. C# pointers are the same as C/C++. Look at the example below. I literally just compiled and ran this on my computer with zero errors.
using System;
using System.Runtime.InteropServices;using SIZE_T = System.IntPtr;
using DWORD = System.UInt32;namespace TestNet
{
[StructLayout(LayoutKind.Sequential)]
struct Foo
{
public int bar;
}static class Program { \[DllImport("Kernel32.dll")\] private static unsafe extern void\* VirtualAlloc(void\* lpAddress, SIZE\_T dwSize, DWORD flAllocationType, DWORD flProtect); private const DWORD MEM\_COMMIT = 0x00001000; private const DWORD PAGE\_READWRITE = 0x04; static unsafe void Main(string\[\] args) { Foo\* pfoo = (Foo\*)VirtualAlloc((void\*)0, (SIZE\_T)sizeof(Foo), MEM\_COMMIT, PAGE\_READWRITE); pfoo->bar = 1; // writes to disk Console.WriteLine(pfoo->bar.ToString()); // reads from disk. } }}
Make a C# console app and paste that code in. WaLa!!
Thanks for sticking with it and being nice and teaching us all something new. :)

i love it when i learn stuff, even if i have to be dragged to it. I'm only curious if this worked in early .NET and I just missed it before, or if it's a byproduct of me dropping development for years and only recently playing catch up.

You don't seem to be taking your own advice seriously - I see you deem it fit to be an unreasonable asshole by starting a discussion with someone by calling them an asshole.

Go ahead, I'll follow your lead. In other words, don't preach what you don't practice. Or simply, follow your own advice.

You started this buddy by being a complete dick and jerk to another member here. You can finish it by just saying "I'm sorry -- won't happen again." Not to me, but to the other member. Or you can just sod-off. Until then expect to be treated by me like I see you treating others.

I had an argument with another member (admittedly heated), and we're through that, and that's that. If you don't like that, you can sod-off (follow your own advice).

I should care? I might have had to take you seriously if you had anything to show as your own contribution to this community, like an article or a few awards. And you're trying to act like you've some business with how two other members have discussed, trolling on a two day old thread.

Contradicting yourself. Typical sign of faulting thinking.

Yeah, you should care. As if you have anything to show yourself. Awards or no awards, doesn't matter. You should care how you interact with others. Be human. Not an animal.

Let me see if I could start it on a clean slate with you. Your primary accusation is that I started off by being rude to this other member. This is untrue, because my first two messages (on different parts of the thread) were: 1. A suggestion that a native programming language is more suitable for performance oriented tasks (not to mention the "should work across platforms" requirement). 2. The op pointed out some "flaws" with the .NET framework, which I said were basically not flaws, but by design. (how could one have raw pointers that could be used for manipulating memory on a framework that promises to automatically manage memory for you?!) The other person basically responded to me telling something amounting to "I worked for microsoft and I therefore don't need you telling me about .NET", which I did not like. I pointed out that working for microsoft doesn't automatically make someone very intelligent. The discussion went downhill from there, and the OP had some condescending stuff to say as well. A bit of back and forth, and the OP said they don't like me and that they will block me. I thought that was fair enough as we had had a heated exchange. But then you show up and falsely accuse me of "starting out by being a jerk" and here we are.
