Hi, I have a problem to read data from serial port COM 1 with my Visual C# program. I have the Framework 1.1 and I use the CreateFile of Kernel32.dll to open the COM 1. The CreateFile succeed and then I try to Read Byte with the ReadFile of Kernel32.dll. This function doesn't work and the GetLastError give to me the 998 Error code that is ERROR_NOACCESS = "Invalid access to memory location". Can you help me please ?

P.S.: I have already tried with MSComm OCX but it doesn't work in my pc.

Do u want to display that In label control or?

yes i want to display it in label control.

There are no WinForms controls provided by Microsoft that parse HTML syntax and display the content accordingly. Infragistics has a control called the UltraFormattedLinkLabel (or something like that) which provides that functionality. If you need that funcionality and don't want to buy the Infragistics controls, you'd need to parse the text yourself and somehow display the contents with the supplied formatting.

Hi, I want to insert into my database some information, I have everything in file a.txt:
INSERT INTO TLK (kodas, liga) VALUES ('(01-99)', 'Traumu priežastys (ne iš TLK10 klasifikacijos)')
INSERT INTO TLK (kodas, liga) VALUES ('01-99', 'Ne TLK10 traumu priežasciu klasifikacija')
INSERT INTO TLK (kodas, liga) VALUES ('1', 'Transporto ivykis')
a.txt contains about 10 000 records. I run this program, but everytime it breaks, it shows error that data would be truncated... how can I fix that?
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;
namespace Kikilis
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
string eilute;
int id = 0;
StringBuilder errorMessages = new StringBuilder();
private void button1_Click(object sender, EventArgs e)
{
try
{
System.IO.StreamReader sr = new System.IO.StreamReader("a.txt");
eilute = sr.ReadLine();
string j = "Data Source=KOMPAS;Initial Catalog=MEDIS;Integrated Security=True";
SqlConnection c = new SqlConnection(j);
c.Open();
while (eilute != "" || eilute == null)
{
SqlCommand cmd = new SqlCommand(eilute, c);
cmd.ExecuteNonQuery();
cmd.Dispose();
eilute = sr.ReadLine();
}
c.Close();
}
catch (SqlException ex)
{
for (int i = 0; i < ex.Errors.Count; i++)
{
errorMessages.Append("Index #" + i + "\n" +
"Message: " + ex.Errors[i].Message + "\n" +
"LineNumber: " + ex.Errors[i].LineNumber + "\n" +
"Source: " + ex.Errors[i].Source + "\n" +
"Procedure: " + ex.Errors[i].Procedure + "\n");
}
Console.WriteLine(errorMessages.ToString());
}
}
}
}

That means that some of the insert statements have data that is too large to fit in the specified maximum size for that field in the database.
Why don't you include the instert statement that caused the error in the error message?

b { font-weight: normal; }

different record every time, for example now it stoped after inserting second record:
in table kodas is nvarchar 100;
liga is nvarcha 150;
INSERT INTO TLK (kodas, liga) VALUES ('A69.9', 'Spirochetu sukelta infekcija, nepatikslinta')
INSERT INTO TLK (kodas, liga) VALUES ('A70', 'Papugu chlamidiju infekcija')
INSERT INTO TLK (kodas, liga) VALUES ('A70-A74', 'Kitos chlamidiju sukeltos ligos')

Without studying your code too closely - are you sure that you are not getting truncation errors because you are trying to insert a string which is too large for the field? ie. a 50 char string when the field is defined as VarChar(40)?
Also, this line:
while (eilute != "" || eilute == null)
looks suspect. While loops normally run while a variable != null.

Hi,
I'm trying to remove checkbox from datagridview column on certain rows.
I have a grid with a datagridviewcheckboxcolumn, in my grid I've got headerrows as i call them and subrows. I want to remove the checkbox from all headerrows but keem them in the subrows.
Does anyone have a solution for that?
regards Tomas

In grid where you are identifying row as headerrow (DataBound event) at the same place you can set visible false of check box.

i've tried that.. but it's a read only property... only returns true or false whether the checkbox is in the visible area of screen... as i figured it anyway...

Hi there 
I seem to remember seeing an article where someone showed how to populate a System.Windows.DataGrid on a Form by using databinding. Almost like how it's done in Asp.Net.
Or is the only way to work with a WinForms datagrid, to databind to a DataTable in the disconnected way?
Kind regards - Jakob
