Base contains an object of Parent, but Parent is a child of Base. Base contains a static Base object (win), but Child, which is a child of Parent, contains a non-static Base object also called win. Sorry, but I am totally confused.

"Sub classing" was a "bad habit" that I had until I decided it was more trouble in the long run.
VB's "component based approach" is actually better in some cases than OOP(s); as in the UI.
I think you should just say "what" you want to accomplish; and you may get some good suggestions on how to accomplish it with less indirection.

Thanks for the replies Richard and Gerry!
I am creating a GUI to connect to a diagnostics tool.
I need to connect to the tool via ethernet and serial connections therefore need to have a class for each connection method.
I was told to have a base class which calls virtual methods in a 'connection' class that are overridden in either the ethernet/serial connection.
I am able to connect to the tool, but when writing information back to the GUI e.g. 'Connected to the tool' etc I am unable to do this..
Thanks in advance for any advice!

The preferred approach is an "interface" ... "one codes to the interface".
You create "one" window, and "inject" the "port" you want; say, via the form's / window constructor; then reference the injected device via its common interface. e.g. (semi pseudo):
interface IPort{
// Properties and methods common to device/com api's
Open();
string Receive();
// etc.
}
// class "implements" interface.
public class MySerial : IPort {
.. Open(){ // custom serial code }
... }
class main {
// Program "instantiates" an obj with said interface.
IPort ActivePort = new MySerial();
...
// Program uses obj via interface.
ActivePort.Open();
etc.
}

Hi Gerry,
Thank you very much for that detailed answer.
I will try implementing an interface as you suggest and see if I can get it to work!
Thanks again,
will report back my progress.

How many times are you going to ask this same question - that's six so far?
The answer isn't going to change:
It doesn't quite work like that.
We do not do your work for you.
If you want someone to write your code, you have to pay - I suggest you go to Freelancer.com and ask there.
But be aware: you get what you pay for. Pay peanuts, get monkeys.
The idea of "development" is as the word suggests: "The systematic use of scientific and technical knowledge to meet specific objectives or requirements." BusinessDictionary.com[^]
That's not the same thing as "have a quick google and give up if I can't find exactly the right code".
So either pay someone to do it, or learn how to write it yourself. We aren't here to do it for you.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

Password to "what"?
Since you don't know that, how do you know it needs to be in C#?
You don't.
Even your emoji is irrelevant.

I am trying to create a function in the GUI where I Logg the values from a textbox and then allow the user to save these values as a .csv file anywhere on the computer.
I have managed to do that, but when I open the files I only see one item from my textbox written in the text file, Why is that ?
private void Logging()
{
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
using (Stream s = File.Open(saveFileDialog1.FileName, FileMode.CreateNew))
using (StreamWriter sw = new StreamWriter(s))
{
sw.WriteLine(textSampling.Text);
}
}
|
|
|
|
|
You are using File.Open(saveFileDialog1.FileName, FileMode.CreateNew) every time, so the file will only ever contain that last item logged. You need to use FileMode.Append as described at FileMode Enumeration (System.IO)[^].

Hi, how am I suppose to implement it with my code.
i have code that is doing almost everything I want, only not printing the contents from the text.Box. The strange thing is, when I use a RichTextBox then everything gets printed into the .csv file I am trying to create. 
Were you thinking about something like this?
private void Logging()
{
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
using (Stream s = File.Open(saveFileDialog1.FileName, FileMode.CreateNew | FileMode.Append))
using (StreamWriter sw = new StreamWriter(s))
{
sw.WriteLine(textSampling.Text);
}
}
|

I already explained, that if you use FileMode.CreateNew you will be creating a new file every time you try to write a log entry. You only need to use that once, at the beginning of a session perhaps*, and use FileMode.Append for every subsequent call.
* You need to use some sort of file name cycling in your programs so you do not overwrite the previously created files. A common method of doing this is to create files with the date as part of the filename.

For "simple" logging, all you need is:
1) File.AppendAllText, or
2) File.AppendAllLines

Itried that but it didnt work

What is "it"?
If it didn't work, you did "it" wrong.

Yes you are completely correct . I did something very WRONG.
Holy Sh*t , I was writing from wrong text box the whole time.  
My initial code actually works;
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
using (Stream s = File.Open(saveFileDialog1.FileName,FileMode.CreateNew))
using (StreamWriter sw = new StreamWriter(s))
{
sw.WriteLine(textSensorValues.Text);
}
}

Been there, done that.

<label class="col-sm-2 control-label">Vehical Mileage<span style="color:red">*</span></label>
<div class="col-sm-10">
<input type="text" name="mileage" class="form-control" required>
$query->bindParam(':mileage',$mileage,PDO::PARAM_STR);
the above is a code im using to insert data into the mileage row, im creating a car rental system, i was wonder if anyone could help me with a code that can relate to the mileage.
say the mileage is about to reach 1000,
when the mileage reaches one thousand the status should change to IN SERVICE.

Sounds like "if this, then that". Just "bind" to something that says "IN SERVICE" or (not) in service, or whatever. Even "blank" is an option. Or "hide" the element ... jeez.
