Yes, tons of people have posted code samples of delegates and threading, pretty much everything you need as far as I can tell from your post. They have posted them here in articles on CodeProject and in many, many other places on the interent. I have no doubt that microsoft has posted them in their documentation as well.
In my experience I have found that using Google can be very helpful at finding such things.
Good luck.

Also take a peek at the SynchronisationContext class. The documentation is good.

Dear all;
Recently our organization needs to convert a 3rd party’s MFC class library into managed code for usage in .NET. In the SDK, there is a header file and a dll library.
I only have little knowledge on wrapping unmanaged code to managed code. I would much appreciate if any one could give advice on how to implement.
Below shows the code in the header file for the dll library. I am quite confused on how to deal with the nested class and callback functions.
////////////////////////////Header File///////////////////////////////////////////////////////
#pragma once
#ifdef UNMANAGEDCODE_API_EXPORTS
#define UNMANAGEDCODE_API __declspec(dllexport)
#else
#define UNMANAGEDCODE_API __declspec(dllimport)
#endif
#include <sys/timeb.h>
class UNMANAGEDCODE_API MainClass
{
public:
MainClass ();
Virtual ~MainClass ();
Virtual bool StartUp(const TCHAR* pcszConfigFileName = NULL);
class NestedClass1
{
public:
// This is the entry for call back function
virtual bool OnNestedClass1() = 0;
};
Bool SetCallback(NestedClass1* callback); typedef struct NestedSruct1
{
unsigned int unId;
__timeb64 createTime;
}NestedStruct1;
const NestedStruct1** GetData(unsigned int& unCount);
};

Hi,
I am using Entity framework in a dynamic data web app with C#.
So far I have created a source file with partial declarations of my entity classes on which I have set attributes like ScaffoldTable.
I did that in order to not lose this code in case of regeneration of the entity classes.
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
namespace AdmissionForm
{
[ScaffoldTable(true)]
public partial class AdmissionForm
{
}
...
}
I would like to know if there is a way to add attributes to the properties defined in this entity classes from the source file I have added.
Regards.

Yes, you can do it using EWS(Exchange Web service)
Exchange Server 2007 provides Web Service (EWS), you have to use those web methods to read and forward those mail.
Brij has already written some nice article on that Exchange Server Web Service Article[^]

OK, this may be a somewhat dumb question but I haven't found a definitive answer yet so I thought I'd try here.
I currently have a client/server WinForms app developed using .NET 3.5 framework. So all my users have .NET 3.5 installed on their PCs along with the application.
I would like to install .NET 3.5 SP1 on my development machine, basically since it's supposed to solve a lot of performance issues with VS2008. However, do I need to have all the users upgrade to .NET 3.5 SP1 as well? That will be a major effort that I don't want to do at this time. So if I'm required to re-deploy .NET 3.5 SP1 to all users in order to run an application developed using SP1, I'll hold off with upgrading my development machine, otherwise I'll press.
Thanks in advance... Steve

Short of just saying "yes it's required", isn't that up to you to answer? I mean you know what your app does, what it uses in the .NET framework, no one else does. So since Microsoft has documented SP1[^], isn't it up to you to figure that out rather than expecting to find a definitive answer from someone else?

I was really hoping for a little assistance as most people here at CP are helpful versus just sarcastic...
That said, I guess what I am really asking is this... If I (A) install .NET 3.5 SP1 on my development machine to take advantage of the supposed VS2008 performance fixes, (B) recompile my application "as-is" (ie making no changes specific to anything in SP1), and (C) deploy the app to my users who still have the "basic" .NET 3.5 framework, will it work?
Thanks... Steve

From my experience, yes it will work, but sp1 adds few functions, if you ship program that uses one of those, it will work as long as this function won't be executed. When it does, exception will be thrown (missing function). I don't know how much of this is help, cause I can't prove it will work the same way everywhere.
But after my app crashed once, I ordered my client to download update and don't whine :P.

Are there any automated programs that can take an .exe and determine whether it references any functions that don't exist in particular versions of .net? To be sure, it would be possible for a program that references a function only found in a later .net version to work with earlier ones if the function is never actually executed, but outside of code specifically written to handle different versions of .net (e.g. try using the new version of a function and set a flag based upon whether it works; if it doesn't work, use the old one instead) I would think the list of functions referenced would correspond strongly to the list of functions required.

I haven't heard of one, but I must say - I wasn't looking for one, so don't take this response as definite answer.

There was nothing sarcastic about my response, I was dead serious. So f*** off a**hole
Ok, look I might have been unfair........ to everyone you currently work with and anyone you might work with in the future. For all of those peoples sake you should look at this[^].

The definitive answer is "Maybe". No, I'm not kidding around.
You're going to have to recompile the app under SP1, then install it on a machine without SP1 on it and test it. It's that simple! It's the ONLY way you're going to get the DEFINITIVE answer.
"led mike" was correct in every way, only YOU can answer that question: "will your app work??" You're not going to know until YOU test it, and that testing is not limited to strictly functionality. The other question you have to answer is performance. Sure, the app may work, but does it do so with acceptable performance??

You could always extend this to

Sp1 contains two types of stuff.
1) New libraries (e.g. the entity framework).
Provided you don't go using these, it won't matter that your users don't have them. You will need to be very careful to make sure you don't accidentally use some new sp1 functionality that your users don't have.
2) CLR improvements. (e.g. various performance improvements to WPF loading times etc). It doesn't matter that your assembly is compiled against 3.5 SP1 on your PC, it will still work on a PC with just plain old 3.5, but you just won't see any of the improvements.
So in theory it should work fine, but as with anything in development, I wouldn't bet your life on it. The best way forward is probably to ensure you test thoroughly on a 3.5 pc without sp1 before deploying it to your users.
