Hi all! i have a read and write function which call from method in other class.. instead of either can read or write at a time,i want to make it both can work at the same time(i want to communicated via serial port).Does anybody know how to do it?
using System;
using System.Text;
namespace yong
{
public class Class2
{
static void Main(string[] args)
{
// Convert string to byte array and send
string x = Console.ReadLine();
byte[] byteDateLine = Encoding.ASCII.GetBytes( x.ToCharArray() );
port CommPort = new port();
CommPort.Open();
CommPort.Write(byteDateLine);
//Convert Byte to String
//string sBuffer = Encoding.ASCII.GetString(dcbCommPort.Read(10));
//Console.WriteLine( sBuffer.ToString() );
}
}
}

Assuming hte port allows it, try running the methods on different threads. Otherwise, each method will only be called when the last method ends. Why do you need them to be intermixed ? I suspect the end result will be the same, in terms of speed, unless you're on a multi CPU machine.

MSDN[^] has plenty of example code.

Well, they would still be on the same thread, but if you put the write and read code in the same loop, that would make them both happen together, but I don't see how it would get faster as a result.

thanks for your advice..i think using thread is better...may you help me to edit my source code using thread?i am just a very new beginner in c#..I need your help a lot.Thank so much!

Using threads is cleaner, but the code is a lot harder to debug, and I doubt it will be any faster, it will just be interspersed, which seems to be what you're hoping for. If you read the MSDN articles, they should give you a good start. Whatever you try, just post your code here if you get stuck ( i.e. as a new question ) and I'd be happy to help.

No, mySQL is kind of crap. If you want a free database, try MSDE, or SQL Server Express[^].

Buy a book on SQL, or download the documentation and samples and look through them.

Again, look through the samples first, read the books online ( assuming they come with Express Ed. ), etc.

ok thanks, what about oracle developer tools for visual studio .net ?? is this an easy-to-use database?

Are you sure they exist ? Oracle is crap, mostly because it's developer tools are crap. Run for your life. Why are you looking to avoid SQL Server ?

I've downloaded microsoft sql 2005 server express. I've also spent the past few hours looking for step-to-step guide to start using and creating a database. However, up till now I still have no idea how to start using this sql server express.
Im wondering, is visual studio .net 2003 compatible with microsoft sql 2005 server express? This is because I only see Deep Integration with Visual Studio 2005 titles/headings associated with microsoft sql 2005 server express.
I would like to know what are the different database systems available that can be used with visual studio . net 2003 (yes, not 2005)..
Thanks!

Hi all!
How do you set a page's timeout duration?
Thanx for the tips!
Kampai!!!

HttpServerUtility.ScriptTimeout Property
Gets and sets the request time-out in seconds.

Oh yeah the ScriptTimeout! Thanx Chris!
Im starting to get the hang of this programming business
Kampai!!!
|
|
|
|
|
Oh hey I've got another question...
Does the ScriptTimeout works like the Page.Response.Expire? I just found the function while exploring Page members. I mean aside from property sets which is in minutes.
Thanx!
Kampai!!!

I have no idea sorry, I just googled it

Thanx Chris! Much appreciated
Kampai!!!

No, the Expires property will just be added to the http header. It's information for the browser on how long it may keep the page in the cache.
---
b { font-weight: normal; }

|
|
|
|
Like a timer on how much time the user has left before the page expires huh? Thanx guffa!

Hello gurus,
I would like to know if it is possible to create a listview control without name in order to have only the pictures in the list? If so how to do that? Or must I do my own control for that?
Note: the pictures are small bitmaps loaded from files. The size of the bitmaps are either 8x8, 16x16 or 32x32.
Thank you.
Best regards.
Fred.

what do u mean by without name, do u mean that there should be no column header or what ? If you want to have no column header then there is no problem but I guess it is something different....
|
|
|
|
|
I mean no string under the picture. I just want a list of pictures...

Set the Text property of the ListViewItem to " " (a space) or even "" (an empty string).
And set the ImageIndex to picture you want to display.
