Thanks Mycroft
Am trying to avoid using Datatable because of Performance. That is why i wanted to use a datareader.
Thanks

You must have an extroadinary amount of throughput to be able to detect the performance difference between reader and table or is it theoretical peformance difference.

So presumably another process is writing the file to the location, I am assuming you are trying to read it while some other process is still writing. Build in a delay for x seconds the first time you see the file and try again.

Hi,
I get the same error. I'm using a FileInfo object with a file name passed to the constructor upon creating the FileInfo object. I check if the file exist and if so I delete it and recreat it. Al works fine first time but when I click on the button again to do the same functionality over again I get same error mentioned. The is NO close method on the FileInfo object nor Dispose. I tried the Refresh() in desprate attemps but still error. Please see a snipplet below:
private void button2_Click(object sender, EventArgs e)
{
FileInfo fileInfo = new FileInfo(label2.Text + ".TMP");
if (fileInfo.Exists)
{
fileInfo.Delete();
}
fileInfo.Create();
int y = 0;
}

Hi Guys,
Mine was a dumbass developer faullt...well... din't realy knew once you create the file the creat method returns a stream  so yea just changed my line of code abit
FileStream stream = fileInfo.Create();
stream.Close()
Hope your problem is as simple as this...

Can we Update records in the table using SqlBulkCopy
|
|
|
|
|
No
Unless you bulkcopy into another table and execute a proc to do the update

Hello! 
I know how to do extension methods and I'm pretty sure I could teach my cat to do them too, but is there a way to somehow have one external method, and use it in several different projects simply by referencing the file it is contained in? Would this be done in a class file ir DLL file? I'm pretty new to this stuff, and would appreciate any suggestions. Thanks for readin'.
Regards,
Jase
private void Yay()
{
DirectoryInfo Di = new DirectoryInfo("J:\\");
FileInfo[] Files = Di.GetFiles("*.*");
foreach( FileInfo file in Files )
{
// Do something constructive.
}
}

Either way could work, to be honest. It's up to you whether you want the overhead of an extra DLL, or you're happy having the code included as a link.

Hi ,
i made a connection string in app.config file. and i want to use this into my .cs file while creating connection object...
objSqlConnection1.ConnectionString = ?
please post the solution..
|
|
|
|
|
if your connection string is like this
add name="conn1" connectionString="string1"
ur access will be like this.
string conn = ConfigurationManager.ConnectionStrings[conn1].ConnectionString;
|
|
|
|
|
thanks !
but it gives an error "ConfigurationManager" does not exist into current context
|
|
|
|
|
add a reference in ur class file.
using System.Configuration;
|

It's said that "Don't have par(my table)" and alway have error with sql_cmd.ExecuteNonQuery(); coz my file have # it can't read #
<pre>
private SQLiteConnection sql_con;
private SQLiteCommand sql_cmd;
private SQLiteDataAdapter DB;
private DataSet DS = new DataSet();
private DataTable DT = new DataTable();
private void SetConnection()
{
sql_con = new SQLiteConnection("Data Source=pare.db;Version=3;New=False;Compress=True;");
// sql_con = new SQLiteConnection("Data Source=pare.db;Version=3;New=True;Compress=True;"); if I want to create new database
}
private void ExecuteQuery(string txtQuery)
{
<big> sql_con.Open();</big>
sql_cmd = sql_con.CreateCommand();
sql_cmd.CommandText = txtQuery;
<big> sql_cmd.ExecuteNonQuery(); </big>
sql_con.Close();
}
</pre>
<pre>
private void LoadData()
{
sql_con.Open();
sql_cmd = sql_con.CreateCommand();
string CommandText = "select * from par";
DB = new SQLiteDataAdapter(CommandText, sql_con);//นำข้อมูลออกมา
DS.Reset();
DB.Fill(DS);//นาม ข้อมูลปายส่ายนาย ดาต้าเซด
DT = DS.Tables[0];
dataGridView1.DataSource = DT;
sql_con.Close();
}
private void button2_Click(object sender, EventArgs e)
{
SetConnection();
LoadData();
}
</pre>
It has error on the BIG 
NO MORE TEAR

indicates you have a problem with your connection string. Probably an invalid path for pare.db Try putting in the fully qualified path as this will be looking in the folder where the exe is created (debug).

I've already tried
It's still "no such table: par"
And what the problem with the # in sql_cmd.ExecuteNonQuery();

Hi

Your suggestions are highly valuable.
Thanks
