Hello Everybody,
Saving strings to files as i know it(from VB6) was similar to this:
struct string
{
int length;
chr str[length];
}
But in C# saving to files is through streaming(correct me if i am wrong) and they only accept arrays of bytes. Okay, I can convert a string to that, but it would be helpful if i didn't have to convert every single integer/long manually.
Anybody has an idea about doing this?
note: Serializing is not an option

(1) Can i move ONE (or two or three) instance(s) of a group of objects to a fixed or moving point? And how do you do that then?
(2)Can i redraw objects in the order of their Y value? And again how?
(3) I i have a large 'room' say, 500 by 500, can i make a view that shows 100 by 100 of the room that you can move around?
(4) Guess what im makin';P

2, get the Y value of the item, and then use refres();
3, use scrollbars...

i made the following stored procedure
CREATE procedure databasecreation (@a varchar(20))
AS
declare @strquery varchar(1000)
SET @strquery = 'create database '+@a+ ''
EXEC (@strquery)
ALTER procedure databasedeletion(@a varchar(20))
AS
declare @strquery varchar(1000)
SET @strquery = 'DROP database '+@a+ ''
EXEC (@strquery)
when executing it in front end C#
code;-
SqlConnection c = new SqlConnection("server=dbasvr03;uid=sa;pwd=sa;database=banking");
private void button1_Click(object sender, System.EventArgs e)
{
String databasename;
databasename =textBox1.Text;
c.Open();
SqlDataAdapter MyDataAdapter= new SqlDataAdapter("databasecreation ", c); MyDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure;
MyDataAdapter.SelectCommand.Parameters.Add(new SqlParameter("@a",
SqlDbType.VarChar,20));
MyDataAdapter.SelectCommand.Parameters["@a"].Value = databasename;
MyDataAdapter.SelectCommand.ExecuteNonQuery();
Console.WriteLine("DATABASE CREATED");
c.Close();
}
AT EXECUTION THE FOLLOWING ERROR COMES-
databasecreation error: identifier 'databasecreation' out of scope
An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in system.data.dll
PLEASE GIVE A SOLUTION

Problem will be there in your stored procedure.
You are trying to alter the procedure on it's definision block itself.
Best way to do this, may split your procedure into two stored procedures.

Through DataGrid.TableStyles proerty you will get the table style which you assigned to the Datagrid.

You try to assign the Table style property to null, then try to assign the second required table stayle property.

write a C function that produces a histogram of the number of occurrence of each letter in a character string. your function should be case independent. your function should have two parameters : the first is a pointer to an array of 26 int that holds the histogram; the second is a pointer to a character string. function return the number of letters found in the character string as an integer

Hope you are aware that this is the C# forum.
Anyway, it's a nice programming task you described, but where is the problem or do you expect us to write the whole thing for you?

Hi,
I need to trap a desktop locker activating along with the screen saver which is activating after 3mins machine idle. I need to by-pass/ Detect this occurance. This can be occured from Keyboard where user types this key combination OR Software generated Even...
I tried with forcefully calling MouseMove after an interval, to deactivate the screensaver... but not succeed..
Please give some ideas....
Thanks in advance....

You can't trap Ctrl-Alt-Del. It's theonly key combination you can't control. Unless you write your own GINA.DLL. Come to think of it, you'll probably have to do the same thing in order to unlock the screen saver.
What are you trying to do with this?

Hiya, Why not check out Paul DiLascia's trapkeys - an excellent piece of code - it might get you in the right direction. It basically involves setting a global keyboard hook and it checks if ctrl-alt-del was pressed, you could easily modify it to set off a flag or something. Google for TrapKeys - it was mentioned in a recent edition of MSDN!
Good Luck,
Tom Brennan.
