Earlier I didnot understand what you meant, now I understand I will work on it.
I get the following error message:
Index was outside the bounds of the array.

I got it to work thanks,

Make sure the size of dsMI[i] is one more than the value after "j <= " in for statement.Also if you are using "<" instead of "<=" put size equal to the value after "<".Check following lines, it will make it clear:
dsMI[i] = new DataSet_MI[size]; // if you use j < size
and
dsMI[i] = new DataSet_MI[size + 1]; // if you use j <= size
Until you realize this message has nothing to say, its too late to stop reading

hi .i have problem connecting the database to the textbox
SqlConnection cnn = new SqlConnection("server=(local); database=pubs;Integrated Security=SSPI");
SqlDataAdapter da = new SqlDataAdapter("select * from authors", cnn);
DataSet ds = new DataSet();
da.Fill(ds);
if i settle the connection above..
how do i connect the data from table authors e.g. 'name' to the textbox..
this.textbox.text = ???????
|
|
|
|
|
this.textbox.text = ds.DataTable[0].Rows[0]["name"].ToString();
|
|
|
|
|
|
datatable's function is to get one record ..
DataTable table999;
string command = "select * from Table1";
SqlDataAdapter father = new SqlDataAdapter(command, myConnection);
DataSet son = new DataSet();
father.Fill(son,"Table1");
table999 = son.Tables["Table1"];
this.aaa.Text= table999.Rows[0]["name"].ToString();
it said tat the father.fill(son,"Table1") got problem
|
|
|
|
|
Because the table name is the one you added in the dataset:
DataTable table999;
string command = "select * from Table1";
SqlDataAdapter father = new SqlDataAdapter(command, myConnection);
DataSet son = new DataSet();
son.Tables.Add("Table1");
father.Fill(son, "Table1");
...
That's work.
But there has only one select statement in your case, why don't you use the index rather than table name?

|
|
|
how to do that in index? can u pls kindly show your code. thanks

As I posted before:
this.textbox.text = ds.DataTable[0].Rows[0]["name"].ToString();

Try passing System.DBNull.Value rather than just null.

I'm trying to make a chat server. I can make a server/client connection and use that to chat back and forth between the server and the client.
But I need to be able to have multiple clients and I don't know how to do that at all.
Can someone help me with this? Is there a tutorial for making a chat server in C# somewhere or an example of one I can look at?

Using Plain Socket connection

Your server program should be multi threaded. Are you using a socket connection ? If yes you have to keep all your client objects in an arraylist for further communication. When a new client is connected, create a thread for him and keep it's object in an array list/list.
