You do know this is a C++ question, not a C# one, right?
But to answer the question, it's OK to have an empty destructor if you don't have any resources to clean up.
In fact, if your class definition lacks a destructor of any kind, the compiler generates one for you which does nothing.
The difficult we do right away...
...the impossible takes slightly longer.

TIL the c++ destructor syntax is valid in c#

"Empty destructors should not be used. When a class contains a destructor, an entry is created in the Finalize queue. When the destructor is called, the garbage collector is invoked to process the queue. If the destructor is empty, this just causes a needless loss of performance." - http://msdn.microsoft.com/en-us/library/66x5fx1b.aspx

Destructors are not magic and do not automatically clean up your resources by just putting the placeholder code there. If you allocate unmanaged objects YOU must un-allocate them.
However, I would advise reading up on the differences between using a destructor versus implementing IDisposable. Destructors in C# are very different than those in C++ and understanding when they are called and what they do is important in how you effectively use them.
See this StackOverflow answer[^] on using IDisposable and finalizers.
Note how the proper use of IDisposable helps you since you, the programmer, have almost no control when the finalizers are run, and absolutely no control about what order they run in (finalizers for unreferenced objects are not guaranteed to run in any particular order, and this could be important).
|
|
|
|
|
To be fair if you do not know how to use correctly create and use IDisposable then it will be just a bad as a destructor.
|
|
|
|
|
In general, you should not need to add destructors to your code.
You can explore the Dispose method.

It doesn't have to go at the bottom. In C#, the way you order your methods has no effect on the way your code performs at run time.
In general, I'm not a big fan of finalizers. Finalize objects are treated differently to objects without finalizers, even if you dispose of the object and call GC.SuppressFinalizer(). Have a read about the freachable queue here[^].

I disabled Lazy Loading for various reasons (Mostly proxy craziness and performance) but I have hit a snag I don't know how to handle.
I have an address table that has a street address broken into parts. One of the pieces is a SuffixId that determines if it is a street, ave, etc... Here is my fullAddress property of the address:
public string fullAddress
{
get
{
string address = number.ToString();
if (direction != null)
address += " " + direction;
address += " " + street;
if (suffixId != null)
address += " " + StreetSuffix.abbreviation;
return address;
}
}
Now my problem is with the StreetSuffix.abbreviation part, I am getting a null reference. How do I handle this?
Cheers, --EA

Why are number, direction and street also notnull. Because you load the information somewhere. I suspect you are not loading the StreetPrefix record.
Never underestimate the power of human stupidity

As usual, you are correct. Forgot to include the StreetSuffix in the Get.

My client has asked me to incorporate text messaging into an app I'm working on. I've never done this before.
1) Do I need to set something up on their server?
2) What's the code look like for this? I've been Googling but found a lot of different samples.
Can someone point me in the right direction?
Thanks
If it's not broken, fix it until it is

A lot depends on what you are doing, at a basic level you'll need an SMS service. If you are doing bulk SMS work you'll need to google SMS providers and find ones that provide an API, I found results googling "sms api" though that'd take a fair bit of digging to get the best deal based on your usuage.
If you need something lower-end, some phones act like modems when connected via USB and provide the functionality google "send sms from my phone connected to pc" and you'll get some joy. It looks like Android plays with this sort of thing really well.
I've not done this sort of work, but I have seen both the above in operation.

Hello,
How can I use WM_PASTE to send a plain text from clipboard to the active window and the focused textbox/combobox ?
----------
I want to paste by double-Click, I can detect the double click event and execute a code when it done
so the destination window will be active the textbox/combobox will be focused
please provide me a little sample project working with a timer in background and do the paste command.
I keep searching for a solution to this problem for days but no results
-------------------
Thanks

WM_PASTE is the message sent to the Window in which Paste operation takes place.
Refer: Link[^]

I understand this
all what I need is a simple example to know how to do it

This message must be handled by the receiving window. When you receive a WM_PASTE[^] message, it is your responsibility to deal with it. You should generally read the contents of the clipboard and past them onto your window, or wherever else your program wishes.

I assume, since you posted on this Forum, you are using C# ... correct ?
Please state in what context you are using C#: WinForms ? WPF ? SilverLight ? ... ?
Whatever you are using: what is it that you double-click on that triggers the Paste Event into the "destination window ... active ... textbox/combobox" ?
Are you saying you want to detect a double-click Event anywhere in your application's main window, or in its child controls ? Does that imply you want to disable the standard double-click functions that occur in certain controls, like a TextBox ?
Not a good idea.
If you double-click on a WinForm the focus of the application may change, depending on what you clicked on; there may be no active Control. For example, if I have a TextBox and a PropertyGrid on a WinForm: if the TabOrder is set so that the TextBox is the Control with Focus when the application starts, then if I click on the PropertyGrid there is no active control on the Form. However, if I double-click on the Form itself, then Form.ActiveControl will still retain its last valid setting.
I doubt anyone here is psychic enough (unless OriginalGriff is here) to figure out what the role of a Timer is in whatever you are trying to build.
If you take the time to describe your problem in detail, I do think we can help you search more "smartly," however. You may be "spinning your wheels" right now as a result of "trying too hard:" that happens to me

I have no problem with double-click event it is already working without any problem
All what I need is to paste from clipboard to the active window and the focused textbox
I tried SendMessage and PostMessage but it is not working with me
