You can't override a member variable.
What is it that you wan't to accomplish?

I really don't think you can override a field, never did it anyway...
I can't see why you would override a field.
Overriding a field isn't really OOP i guess ...
But if you really want something that is close to the thing you want, you can use properties:
Instead of this:
public class BaseClass
{
protected int i;
}
public class ClassChild: BaseClass
{
//how to override i ?????????
}
use this:
public class BaseClass
{
private int myInt = 0;
protected virtual int i
{
get
{ return myInt;}
}
}
public class SuperClass : BaseClass
{
private int otherInt = 0;
protected override int i
{
get
{
return otherInt;
}
}
}
I didn't implement the set, it is just to show you the picture

Hello
I have written SQL query which returns data in XML form
now i want to catch this data in my C# code
Iam using a dataset
after catching this data i want to upload it in DOM
or an abject of type XmlDocument.
Please tell me the steps
the xml data is of this form
< m attr1="1" attr2="00">< /m>< n attr1="1">< /n>
< m attr1="1" attr2="00">< /m>< n attr1="1">< /n>
< m attr1="1" attr2="00">< /m>< n attr1="1">< /n>
that means there is no root element and tag names
are repeated
Thanks,
Sana

Example:
System.Data.SqlClient.SqlConnection conn = newSystem.Data.SqlClient.SqlConnection("server=pc1;database=northwind;trusted_connection=true");
System.Data.SqlClient.SqlCommand cmd =
new System.Data.SqlClient.SqlCommand("SELECT * FROM Customers For XML Auto", conn);
conn.Open();
System.Xml.XmlReader reader = cmd.ExecuteXmlReader();
while (reader.Read())
{
System.Xml.XmlDocument xmldoc = new System.Xml.XmlDocument();
xmldoc.Load(reader);
}

Sorry! Previous example was incorrect.
System.Data.SqlClient.SqlConnection conn =
new System.Data.SqlClient.SqlConnection("server=pc1;database=northwind;trusted_connection=true");
System.Data.SqlClient.SqlCommand cmd =
new System.Data.SqlClient.SqlCommand("SELECT * FROM Customers For XML Auto", conn);
conn.Open();
System.Xml.XmlReader reader = cmd.ExecuteXmlReader();
System.Xml.XmlDocument xmldoc =
new System.Xml.XmlDocument();
xmldoc.Load(reader);
conn.Close();

Just discard any lines you don't want, I assume you want to read in the alternate lines. In this case something like which follows should work.
using (StreamReader sr = new StreamReader(filename))
{
while(sr.Peek() != -1)
{
sr.ReadLine();
string line = sr.ReadLine();
}
sr.Close();
}

XML or ini files ?
The way you do it is not readable for any other programmer, if anyone want to edit your code or has to take over your project, they will have a hard time to learn what that file stands for ...
In XML or ini you can at least comment (in your code, or in the text file itself).
Don't you also love the code?

I'm busy with my app installer, so what I did was include the msde with the installer. Now what I need to do is check whether the sql services are running and attach the database to the instance.
So I started creating a console app to help with the command line arguments, but I don't know how to execute commands with the console app.
Any help will be appreciated.
Thanx in advance

Thanx for the reply, I think I found an answer to my question, only problem is that all the examples I get is in VB, I tried to do my own translation to C# but it doesn't work, I you can maybe have a look a bit up at my last post.
Many thanx

Why did you start a new thread when it is obviously a continuation of this?
|

I thought it being more with the issue of the translation from vb to c# I'll put it under a new heading.

If you mean "SQL Commands" then you execute them in exactly the same way you would in any other applications. You just cannot use the wizard to write the code for you.

You can set the command argument to get the value in itemcommand event.
BTW better you put this into asp.net forum there you will get more responses.

I have a windows form that has a bindingnavigator that binds several bound textboxes, datepickers etc. Works great  .
What I want to do is display the contents of a text file that is related to each record bound by the above. For example, if record 23 of 50 is currently in view then the contents of 23.txt are displayed in the textbox.
How do I go about that?
Thanks,
Glen Harvy

It's probably stemming from the SELECT statement. It's bad practice to use a * to denote which fields you want from the table. Start be rewriting the SELECT statement to specify which fields you want, including the Primary Key.
SELECT keyfield, field1, field2, field3 FROM ActivityReport

is there a label control that can support bold or different color on the same line. by using tags like in HTML?
sample:
This is a test for bold and this for color
i want to implement this without using richtextbox
can anyone please help

As far as I know there is not such a control. You could, however, write this yourself fairly easily. One approach is to derive a class from Control. Your Text property would contain the text with any meta tags that you would define. In your OnPaint method you would render your text with colors, fonts, etc. based on any meta tags you may have.
I hope this helps.
