DataGridViewTextBoxColumn MyColumn = new DataGridViewTextBoxColumn();
myDataGridView.Columns.Add(MyColumn);
Try that. Syntax is off the top of my head, so you may have to modify things slightly, but at runtime, that's the way to do it. In the designer, right click the DGV and select "add column"

Hi all,
I have to start with a 3d game soon. So could please suggest me how is C#.NET for creating 3D games. Because i have heard C++ is the best option to create 3D game but C# is much simple than C++ so i am planning to use C#.
But i am not sure if C# gives all the functionality like C++ or not. Because i dont want to have a situation like in the mid of my project thinking that i should have used C++.
So please guide me the right path.
C++ OR C# is fine ?
Thanks

Since DirectX9 .Net has full support over DirectX and form what i have been told execution speed is very close to C++.
If i started ever again creating a game I would surely chooce .Net for DirectX9.

If the two databases are on the same server then it is quite easy
You can fully qualify table names if you need to
[server].[database].[owner].[table]
[owner] if it is dbo can be omitted.
[server] can be omitted if both items are on the same server.
INSERT INTO destination_database..login
SELECT * FROM source_database..login
If the tables are on different servers then it becomes more complicated as you have to link the servers together first.

What is going wrong ? Does your connection fail ? What error do you get ?
I assume this code is not involved in the login process ? I also assume you haven't really called your button 'button1' ???

Gautham

|
|
|
|
|
y cant u just give insert........values(textbox1.text.tostring, textbox2.text.tostring) instead of all the parameters!!!!

Because parameterised queries provide some protection against SQL injection attacks.

That would introduce vulnerabilities into the application. You really MUST read SQL Injection Attacks and Tips on How to Prevent Them[^] before giving out any more advice like this.
Also, myTextBox.Text returns a string already. So there is zero need to append ToString() on that.

He's plainly using SQL directly, you can see it there.

Other than the obvious security issue of storing a password in plain text I don't see anything wrong with this. What error are you getting?

*grin* I asked that, a half hour ago....

Do NOT delete your query because it makes it very difficult for those with a possibly similar problem to find out the answer!!!

hi
I read msdn about collection and I understand
that when I want to make a collection of int,string etc.
I can use arryList but if I use objects I need to use collectionBase
the questions are:
1. why?
2. before I knew this fact i used arraylist to collect Labels Points
and I didn't have any problem during running the application.
so it seems that I can use arraylist for objects...
thanks
shaul

yes arraylist can have objects.

Where did you get that? As you noticed yourself this statement is wrong. One could say that you should use a custom collection derived from Collectionbase, because that custom collection can be made type-safe i.e. you can only add instances of a certain type and also only get instances of this type. In .NET Framework 2.0 you can use the generic List type, that is similar to the ArrayList with the advance of type-safety.

You're using C# 2003.
An ArrayList contains a collection of objects. That's all it can contain. In C#2005, generics mean you can specify the type of objects that go into a collection. In C# 2003, EVERY collection contains objects, and that's all.

thanx graus.
i have checked login,now i want loginid n password which user enters in textboxes into another database.
i m a student of computer science doing project work.
i m trying this code, but no effect :
private void button1_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection("Data Source=PROGRAMER;Initial Catalog=statusutility;Integrated Security=True");
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
con.Open();
cmd.CommandText = "INSERT INTO login(userid,password) VALUES (@pUsername,@pPswd)";
SqlParameter p1 = new SqlParameter("@pUsername", SqlDbType.VarChar, 50);
p1.Value = textBox1.Text;
cmd.Parameters.Add(p1);
SqlParameter p2 = new SqlParameter("@pPswd", SqlDbType.VarChar, 50);
p2.Value = textBox2.Text;
cmd.Parameters.Add(p2);
con.Close();
}
can u plz help on it?
Thank You.
Nekshan.

This code cannot have any effect, because you never execute the query. Insert cmd.ExecuteNonQuery(); before you close the connection.
