Why are you expecting the control of a robot to be an appropriate first project ? If you have experience in another language, you should use that, and if you don't, then you probably don't have much hope.

I doubt there's a pattern which is going to provide a panacea to your task. It's not typical for a pattern ( unless it's MVC, which is not a GoF pattern ), to define the nature of an entire project.

hey thnx for the reply but new ..means with hardware.. iam in website development already more doesnt mean i dont knw .. ..well its more like this but have to code in C# http://www.mavrinac.com/projects/robot/[^] regards therz always hope

Oh, OK. Well, you need to work out how to communicate with your hardware. If the robot uses the serial port. C# 2005 has classes to communicate with that port, so once you work out what you need to send, it shouldn't be too hard.

yes it does work on a serial port ok ....iam getting it but its all kinda mixed up i mean wht will be to exact proecdure to follow to program microcontroller in c# or to program servo motors ..? iam usin rs232 which i serial..can u help me with the exact steps..

I doubt you can program the microcontroller in C#. I'd imagine that would be C or C++.
C# would likely be useful only for writing code on the PC end.

ok now i get it .......so i will be using c++ or c for serial progromming for communicating with the hardware ......u mean microcontroller .with tht servo motors .......is there any ..open source or link which can help

I mean, if you need to program the device, it will probably be C. For a Windows program that controls the robot from the PC, C# will work fine.
No, I've never done this. What about the article you linked to ?

i did some work using an OOPIC controller which connected to my PC via rs232.
Essentially the code was built in 2 parts. there was a stack of code written in OOPIC language and deployed on the controller board. This took care of things like making sure the servos didn't turn too far and the rates at which they moved when commanded. It also had a list of actions that it should carry out and some messages it could send back to the PC.
A winforms app sat on the desktop and sent messages down the wire to the controller.
The user might select straight on from a list of options in a combobox and select 50% on a slider to determine the speed.
The app then sent a message of 1 128 down the serial cable.
The program on the controller knew that 1 meant left and right motors equal and used the next number to be the speed in this case 128/255 of full power.
I guess that's a pattern of a sort. Keep the hardware logic on the controller at the hardware end and the more abstract concepts(go forward, turn slowly, spin on spot) on the computer.
I think serial things have improved in 2k5, i remember 2003 was a bit of a pain for serial coms.

can u tell me more about the deployment of code which was burn to the controller tht part i need really help ...how to do?
|
|
|
|

the controller came with a small but effective IDE for writing code to run on the controller board. I would assume that the manufacturers of your controller will provide either an IDE or a set of libraries for you to use to develop the code that runs on it.

Hi all
I read about interesting feature in MyNamepsace coming from Microsoft.VisualBasic.dll
I added a reference to Microsoft.VisualBasic.dll in my C# project, but I cannot see any classes of MyNamespaces.
Do I have to make further settings?
regards

No, the 'My' namespace is just a little bit of hand holding for the VBers, it adds literally nothing to the language, it's just a shortcut to a bunch of commonly used stuff through the framework.

It's more like training wheels for your car in case you miss the ones on your first bicycle too much. 
|
|
|
|
|
Or perhaps it's more like steering wheel, pedal and seat covers, so that your new BMW 330 feels just like your old Renault 5...

Hey! I enjoyed my Renault 5, two cars before my first BMW, but I know exactly what you mean.

i m making an application in c#.net2005, window application.
How can i connect datagridview to database(sqlserver2000) at runtime? - not from design, only by coding.
i have written this code, but no data is listed in grid :
SqlConnection conn = new SqlConnection("Data Source=......");
private void Form1_Load(object sender, EventArgs e)
{
conn.Open();
SqlDataAdapter da = new SqlDataAdapter("select * from tblsummary", conn);
DataSet ds = new DataSet();
da.Fill(ds, "tblsummary");
//dataGridView1.Columns.Add(sitehit);
dataGridView1.DataSource = ds;
conn.Close();
}
Does i miss something else for connection?
Hope to get a reply..
thank you in adv.
nekshan.

private void Form1_Load(object sender, EventArgs e)
{
' Create Instance of Connection and Command Object
Dim myConnection As SqlConnection = New SqlConnection(System.Configuration.ConfigurationManager.AppSettings("ConnectionString"))
Dim myCommand As SqlCommand = New SqlCommand("select statement", myConnection)
' Execute the command
myConnection.Open()
Dim result As SqlDataReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection)
DataSet ds = new DataSet();
da.Fill(ds);
dataGridView1.DataSource = ds.tables(0);
}
convert this in c# some code is paste from vb.net that's y.

Dim myConnection As SqlConnection = New SqlConnection(write u'r connecting string over here)
in prev code.

da.Fill(ds);
what is 'da' in your code? no definition for it.

thanx its working.
www.meebo.com is not allowed 
i'll try again.
how r u?
wen r u coming??
c u soon!!

just an alternate method by using the data reader
SqlConnection conn = new SqlConnection("Data Source=" + Environment.MachineName + "\\WINCC;Integrated Security=SSPI;Initial Catalog=Logger; Packet Size = 32766;");
SqlCommand cmd = new SqlCommand("SELECT * FROM RDPLogViewer WHERE SubSystem = '" + SubSystemComboBox.Text + "'", conn);
SqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
LoggerDatagrid.Rows.Add(rdr["TypeLevel"].ToString(), rdr["TimeStamp"].ToString(), rdr["SubSystem"].ToString(), rdr["ClassName"].ToString(), rdr["FunctionUsed"].ToString(), rdr["Memory"].ToString(), rdr["Statement"].ToString());
}
Assuming that the variables are existing in the respective tables/database
