This makes no sense, did your post contain tags that have been stripped ? You can't do generic interfaces AFAIK.

I have no idea what you mean. Your post doesn't make sense to me.
However, maybe this helps:

public interface Abase<T> {
    string Xyz(T arg);
}

public class A<T> : Abase<T> where T : class {
    public string Xyz(T arg) { return arg.GetType().ToString(); }
}

By setting the text property on the labels. IF you need to use it twice at the same time, create the whole thing as a user control, and then put two of them on the form.

Hi all, I am trying to insert data into sqlite datetime, but it seems like making my life really deficult.

this is what I have done to do this;

con.Open();<br />
                cmd = new SQLiteCommand();<br />
                cmd = con.CreateCommand();<br />
                cmd.Connection = con;<br />
                cmd.CommandText = " INSERT INTO Hall_Call_Up (Call,Time) VALUES ('1','" + dateTime.Now.ToString("YYYY-MM-DD HH:MM:SS") + "')";<br />
                cmd.ExecuteNonQuery();

this is giving me error saying "Unable to read data"

But if I connect to datagridview and I do this;
this.hall_Call_UpTableAdapter.Insert(1, DateTime.Now);
it is working.
Can some one please help me.

thanks

The string your using will create an incorrect and unparseable DateTime string (read the MS docs for the correct DateTime templates).

The template you DO want is this: "yyyy-MM-dd HH:mm:ss".

You have to return the newly created ID's from the first insert and update your data before sending the second insert.
A better solution may be to parcel the whole data set up as xml, pass it into a stored procedure, then you can process the whole lot in one shot.

Cookies are used to persist data on the client so that it can be reused by your web page when it is next loaded. Session variable are similar, but on the server end. However as these are linked to a particular session ID they will go away after a bit when the client leaves your web site as they are stored in memory. However, cookies are saved to disk, and may be deleted by the end user.
Many sites do not use either, and don't need to.
It all depends what you want to do, and how you want your web app to work.

I think the window is closed at this moment.
Can't you send a message to the process?
