Yes, using string.Format is good. Seems I've been going down that road lately

halloo ..
i'm newbie in ADO.Net.
i want to ask about trigger in sqlserver2000.
i develop ado apps with c#. my case is ...
client 1 open add employee form, client 2 open list of data employee.
client 1 add employee data. if client 2 doesnt click button refresh, so new data is doesnt appear, right ? so i want sqlserver make the trigger to the client and auto refresh the list data so that the data auto appear in list without user in client 2 click resfresh button or the application make auto refresh with function.
thanks.
thanks vian.

It's possible to write .NET code in SQL Server 2005. This MAY allow you to do what you want. In SS2000, it is not possible.

so, what must i do ? could you help me how make the trigger is ?
thanks

Like I said, SS2000, you can't do it. Your best bet is to poll the database regularly, but of course, this means a lot of network traffic.

Welllll....not quite. It IS possible, but you have to install the SS2000 version of Notification Services. Docs on it are here[^].
I looked at it a few years ago. It'll require him to rewrite a good chunk of his database code to support this though...

OK, that's one of the things I never install. Fair enough, glad you were around to call me on it

I saw that there are some articles on writing device drivers using C++ but I can't seem to find anything on writing device drivers using C#, even on Google. Is doing this possible? Anyone know where I should look to start?
Thanks in Advance

AFAIK, device drivers need to be written in native code which C++ qualifies and C# doesn't.

AFAIK that is correct, drivers and kernel stuff require unmanaged code only.

My pleasure.
It will be a while before a Windows Operating System could be written entirely in managed
code; one of the problems is the unpredictable (hence not real-time oriented)
behavior of garbage collection.

Yeah, the word "real-time" is the key. With the overhead of the safe and reliable coding of the managed languages, they will be only suited for application/web programming.

So if you're taking a course in C#, it's a good thing of they also mention unmanaged code, and tell you how to use that in C#, or else many doors stay closed?

Well, it depends on your goals and objectives. If you want to be mostly an application or web application programmer, C#, VB.NET and Java are well suited for that job. However, in some real-world situations, you cannot avoid programming in native code such as C and C++. From my experience, most of my coding with managed code required reporting data from the "secondary" source such as an Oracle Server. I use native (unmanaged code) to obtain real-time data from a primary source such as a machine or gage on the plant floor.
In a nutshell, knowing both managed and native languages means you are a more flexible and resourceful programmer. However, you also need to understand or be familiar with your programming enviroment to apply your programming skills. Thus, understanding what is going on underneath (WIN32) the Window Forms application, will foster creative ideas on how to go beyond what .NET is allowing you to do. Many a time, a customer has asked me to do something which .NET does not directly support out of the box, and, usually, I have to go back to the native environment and the required native coding.
I hope there is a message somewhere up there!

P.S. IMHO, I think the GC manages memory a lot like NTFS does a hard drive. If you have a lot of small and big files, and a lot of files are being added and deleted, if a file does not fit into a current empty spot. Instead of moving files around to make room (time consuming), it will place it in the biggest void of the hard drive.

Can any one please explain me what exactly the below code is doing. I know its replace function but i am not getting it...may be a long gap from programming... ~ ?
<br />
public static void Replace(ref byte b, int pos, byte value)<br />
{<br />
b = (byte)(value == 1 ? b | (1 << pos) : b & ~(1 << pos));<br />
}<br />
Thanks

Hi,
what is the problem, don't you own a book on C#?
and can't you run the code?
then split the line in a couple of lines and look at intermediate values?
this is a normal assignment statement that modifies the content of b
by either setting one bit in it, or clearing one bit in it.
if value equals 1 it ORs b with 1<<pos which="" is="" bit="" number="" "pos"="" (zero-based="" counting
from="" right="" to="" left);="" otherwise="" it="" ands="" with="" the="" logical="" complement="" of="" same.
if="" you="" want="" do="" some="" real="" programming,="" i="" suggest="" hold="" your="" own="" spoon,
and="" feed="" yourself="" as="" much="" possible.

Sorry Luc Pattyn,
I am a little slow in answering! I like that spoon saying.

This information is well documented. Anyway, ?: is a conditional operator:
condition ? (first_expression) : (second_expression)
where the first_expression is returned when condition is true else the second_expression is returned. The condition is (value == 1). The first_expression is (b | (1 << pos)) where b is being operated on by bitwise OR with 2pos. The second_expression is (b & (1 << pos) where b is being operated on by bitwise AND with the bitwise complement of 2pos. The result type of both expressions is an integer type and needs to be casted to a byte.

The code looks like it was written by someone who thought himself clever. 
Perhaps the code would be clearer as:
public static void Replace(ref byte b, int pos, byte value)
{
byte temp = (byte) ( 1 << pos ) ;
if ( value == 1 )
{
b |= temp ;
}
else
{
b &= ~temp ;
}
}
Though that still doesn't explain the purpose of the routine, and its name.
