Nice. Line 360 just reads a string, so the device outputs text, which you can look at
with HyperTerminal.
And Line 370 turns the text into a number, in C# that would be something like
int.TryParse() or float.TryParse().
As I said before, it's time to google and experiment about the control lines;
your PC probably must set some lines high/low otherwise the device may not respond.
Alternatively, you could just give it a try, open HyperTerminal, open a connection
at 1200 baud, and type ESC P ENTER, just to see what if anything comes in...

Luc, I really do appreciate your time an effort.
I have been on this for 2 days, hours on googles etc...
The thing is we also have a MFC application that works (not the source code though) fine but I need to do it in the .net framework for loading onto handheld devices.
I will investigate further and post the answer if even, when ever I find it.
Thanks again.

You're welcome.
One more idea: if your serial cable is not a commercial one, but something someone
assembled from scrap, then you might be able to see the actual number of conductors
used; the fewer there are, the fewer things you have to worry about. So if there
are only three conductors, it should always work in HyperTerminal.
If on the other hand all 9 (I presume it's a DB-9 connector) pins are wired, then
chances are you have to set all output control lines (about 3 or so) to the right
polarity.
Apart from that, there really should be no problem at all.

A bit of searching found this - hope it helps. With the source code you have you should be able to recreate it - Good luck
OPEN "COM1:[speed],[parity],[data],[stop]" FOR [FILEMODE] AS #FileNumber
CD0 = zero milliseconds timeout on the data carrier detect line (DCD)
CS0 = zero milliseconds timeout on the clear to send line (CTS)
DS0 = zero milliseconds timeout on the data set ready line (DS)
RS = suppress detection of request to send (RTS)

Ok, I was trying to connect a PC(XP pro) to a SARTORIUS lab balance model BP3210S and also model 1413. Via Serial rs232
I finally made it work.
The main problem was the escape sequence sent to the port.
Here is the code.
Create a Windows C# project with 1 textbox and 1 button and drop this code behind form1.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Windows.Forms;
using System.IO.Ports;
namespace AnotherSerial
{
public partial class Form1 : Form
{
SerialPort sp = new SerialPort("COM1", 1200, Parity.Odd, 7, StopBits.One);
public Form1()
{
InitializeComponent();
//Subscrib deleguate to even
sp.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived);
}
private void sendButton_Click(object sender, EventArgs e)
{
try
{
textBox1.Text = "";
char cCHR27 = (char)27;
sp.ReadTimeout = 500;
if (sp.IsOpen) sp.Close();
sp.Open();
sp.DtrEnable = true;
sp.Write(cCHR27 + "P"); 'Escape
}
catch (System.Exception ex)
{
textBox1.Text = ex.Message;
}
}
private void ReadButton_Click(object sender, EventArgs e)
{
try
{
//clear the text box
textBox1.Text = "";
//read serial port and displayed the data in text box
if (sp.IsOpen) sp.Close();
sp.Open();
//textBox1.Text = sp.Read() + " Received";
}
catch (System.Exception ex)
{
textBox1.Text = ex.Message;
}
}
private void port_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
// Event for receiving data
// Read the buffer to text box.
this.Invoke(new EventHandler(DoUpdate));
}
private void DoUpdate(object s, EventArgs e)
{
textBox1.Text = textBox1.Text + sp.ReadExisting();
}
private void Form1_Load(object sender, EventArgs e)
{
}
}
}
It works
Thanks all.

Hi!
I'm creating an application using C# and I need to display one or more markers in a webBrowser object using Google Maps.
The problem is that I was thinking to create only one HTML file that I could change automatically everytime I need to display something. Like this I need to edit this file with the right code (HTML and JavaScript) and than open it in the webBrowser object. This file would be located on local disk and not on a public website.
Do you think that this is the best way to do this? If not, what do you think i should do?
If it is, how can I edit a HTML file using C#?
Here's an example:

Thanks in advance !!!

Thanks for the tip!
I'm going to take a look at the MSDN code that you post it.
Looks to me that it can help me.
However, I still don't know if this is best way to do this kind of implementation.
Any suggestions will be welcome.
Thanks!

I had to do the same thing last year. What I intended to be a c# application turned out to be mostly a javascript application. The only part that was c# was building the coordinate file to be used by the javascript.

Hi, thanks for your post!
And you made it like this or not?
Can you explain me, in a very brief way, how did you implement this?
Thanks!

Hello!
I'm having a strange problem with a combobox I have added into my DataGridView object.
While runing my program, rows are added in to the DataGridView. When I check in the ComboBox, I can't see or use my collections items which i entered in the Edit Columns property window!  Why is this happening?
I also want to know how to insert own items to the collection while running the program.
Hope someone have some answers!

I create a DataSet with 4 tables in it from a mdb file using the Wizard of the VS Express 2008. I have a DataGridView and I display the data of the "Transaction" table. I also have a table with my suppliers called "Suppliers". In "Transaction" table I have a column called "Supplier".
I have enabled the options to add,edit or delete record in the DataSet and to save all the changes back to the mdb file. To provide an easier way for the user to add new records I set "Supplier" columnType in the DataGridView as DataGridViewComboBoxColumn and DisplayMember, DataSource and ValueMember to the "Name" column in the Supplier table so the user can directly select the name name of the supplier without having to type it.
So when I run the program and load the form I get the following error message:
System.ArgumentException: DataGridViewComboBoxCell value is not valid.
Any help would be appreciated....
Thank you

yeah that DataGridViewComboBoxColumn is a tricky lil bugger!
ive had a problem with mine for almost two weeks now. but my problem is that the table in question references itself
good luck tho

Check the AutoSizeMode property of your DataGridView.
You may have set some column(s) to expand the column width to fit the data. Depending on what data you have there (or actually you don't have  ), you will get that kind of error if the lookup is turned on.

Make sure the different computers have the .NET framework installed and the correct version for your application.
If you make a setup project you can make it detect this and download the framework during install.

Thnks all
But it's very small project..It works fine in other PC's having .NET Framework..
Do i need to add some configuration file so that it works fine everywhere without taking care whether .Net Framework is installed or not..
So sorry for simple question...I just start working in c#..
Ash..

If the correct version of the framework isn't installed it will not run.
If the other PCs are running Vista and your app requires administrator rights then you'll need to add an application manifest so UAC prompts for it to be allowed. I've mentioned this before somewhere, I'll try and find the link.

I can't find it but it's very simple.
How to prompt for UAC elevation in Vista.
In Solution Explorer, right click your project and select Add|New Item. Select Application Manifest File and click Add.
In the app.manifest file, change the line that reads
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
to
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
