No. Members that need to be accessible by derived classes should be declared protected (or public if they should also be accessible by clients).

Thanks Ravi!
Do you know why the feature of specifying the inheritance at the class level is not provided there unlike C++? Are you getting what I am trying to say?
e.g. can we write,
class MyDerivedClass : Private MyBaseClass
in C#.
If we can't then why?
Have a nice day!
Thanks,
...G.

Inheritance in C# has been designed to be more formal than C++. Along with explicit inheritance rules, C# also restricts class inheritance to a single base class (although it does permit a class to implement any number of interfaces).

Hi,
does anybody know a printer controller for Visual 2003?
I would like to make a function that will print directly after clicking on a button.
Thanks,

You actually expect us to view *all* of those?
Aside from the fact that they appear to have been stolen from traincert, why would I want to do that?
The posting is almost certainly a copyright violation.
My idea is that you should remove the postings and delete you post before the publisher of those training videos sues you, or charges you with theft.

Hello,
(call it my laziness or my haste that I am post a question straight here instead of consulting the reference books)
I have a point class in my project called FoxPoint, can I make a 2D array like this:
FoxPoint[,] strokes = new FoxPoint[4, 10];
It's giving me strange errors:
Error 1 Inconsistent accessibility: parameter type FOX_CSharp.FoxPoint[*,*]' is less accessible than method 'FOX_CSharp.ConComp2Form.DrawBoundries(FOX_CSharp.FoxPoint[*,*])' C:\...\FOX_CSharp - Integrated - Aug 05 06\FOX_CSharp\ConComp2Form.cs 195 21 FOX_CSharp

You have something wrong with "public" and "private". Change all to private or change all to public to solve it. See this:

I thought the same when I first looked at the error message, but the funtions is public. Do I need to put 'public' before 'class' as well?

DrawBoundries is public, but takes an argument FOX_CSharp.FoxPoint[*,*] that is less accessible (e.g. private). To call the function, you actually need a FoxPoint, so the funciton can be called only as if it were private.
You need to make FoxPoint public, too.

I'm not sure that you can. I've not found a way

You can't. You'll have to use a 3rd party library, like this[^], to do it for you.

Not meaning to sound cocky but doesn't this mean you can do it? If the third party company has done it, or do you mean it can't be done in C# / .NET?

Noone's figured out how they do it yet, but I suspect they rewrote the API's Outlook is using, and left out the Security junk. That could be done in any language, but it's a lot of work just to get around that warning.

hey
i am developing a web application using asp.net, but coding in C#.

i have two textboxes.. watever the user enters in it, it shud be added in a particular table.

You take the values and run the query through an SQLCommand Object, that's the simplest solution...

i coded a bit.. but now sql database i showing an error if i keep the field "Username" as a primary key.
firstly the data is entered in a very ad-hoc fashion.. there is a row empty at the top...data entered in between two rows which are already filled with data..
and if i delete some data,then i get the error as
"Another user has modified the contents of the table,the database row ur modifying no longer exists in the database....... violation of PRIMARY KEY constraint...."
THE CODE:-
try
{
SqlConnection conn = new SqlConnection("server=(local);" +
"database=path;" +
"connection timeout=3;" +
"Trusted_Connection=yes;" +
"Integrated Security=true;" +
"user id=sa;" +
"password=");
conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.CommandText = "Insert into login(Username,Password) values('"+uname.Text+"','"+pass.Text+"')" ;
SqlDataReader dread = cmd.ExecuteReader();
if (dread.Read())
{
failed.Text = "Could not add the user";
}
else
{
Response.Redirect("success.aspx");
}
conn.Close();
}
catch(Exception kp)
{
failed.Text=kp.Message;
}
}

Hey all,
As mentioned in one of my earlier posts, I'm currently coding a class which inherits from System.Windows.Forms.Button.
My goal is to create a ShapedButton class, with a built in functionality to shape the button according to a drawing in a Bitmap object.
I do not intend to write a new UserControl, encapsulating a button.
My intension is to directly inherit the Button class.
However, the problem is that it would be immpossible to design my ShapedButton in design view, and I would have to manually write the code to InitializeComponent().
How can I use my ShapedButton in the designer?
Do I have to create a UserControl?
If that's the case, then how can I inherit Button? There's no multi-inheritance, and I would have to inherit UserControl first...
Thanks in advance,
Shy.

Do NOT write any code in InitialiseComponent, the IDE recreates that code.

You can't, as you say, once you inherit from UserControl, that's it, excepting for interfaces.

What can I do than in order to gain the ability to design the button in the designer?

It's not exactly what you wan't, but it might help you out a little bit because it enables you to use at least some designer abilities. To outwit the designer do the following:
Let's say you have a class MyButton derived from Button. To place an instance, first place a usual Button Control on your form by using the designer (let's name it myButton1). In your code replace the designer generated code private System.Windows.Forms.Button myButton1; with private MyButton myButton1; and in InitializeComponent() use your own class, which results in replacing this.myButton1 = new System.Windows.Forms.Button(); with this.myButton1 = new MyButton();. This should make the designer switch to your own data type permanently and your own properties and events should also be listed by the designer. Hope this helps.
