Hi,
I didn't tried this before, but I think one possible solution is to use the TableNewRow-event. This event will be fired every time a new row is inserted into the datatable. What you can do is to register for this event (at the datatable) and then within the handler you can update your progressbar.
Hope this helps.
Regards
Sebastian

Thank you for the Tip, but it doesn't work, because i created the database-application with the Designer and so, the datatable is private. I only have access the bindingsource- and the datatableadapter.

n can represent 0, 1 or many. If you want to force a one-to-one relationship then you can put a second relationship in place 1-to-many going in the opposite direction. If you have two tables with a one-to-many and a many-to-one between them they end up forcing a one-to-one. (Actually, not quite - You can have a zero on one side, i.e. one-to-zero)
I'm curious. Why do you need a foreign key? Surely the primary key of of both will be the same?
one-to-one relationships can also be symptomatic of two tables that ought to be one table. Have you explored this possibility?

This example attaches two files from pubs to the current server.

sp_attach_db is a system stored procedure that is in the SQL Server master database.
If you really don't want to use it, you can use what is below (which is all the sp_attach_db does).
Also, I put this in vb.net - the last thing I posted was C#.
Imports System.Data
Imports System.Data.SqlClient
Dim conn As New SqlConnection
Dim myCommand As SqlCommand
conn.ConnectionString = "Data Source=(local);Initial Catalog=master;Integrated Security=SSPI"
conn.Open()
myCommand = conn.CreateCommand()
myCommand.CommandText = "CREATE DATABASE [ATestDB] ON (FILENAME = 'C:\TestPath\ATestDB_Data.MDF'), (FILENAME = 'C:\TestPath\ATestDB_Log.LDF') FOR ATTACH"
myCommand.ExecuteScalar()
Just change the name of ATestDB to whatever yours is, and the paths and filenames too.

(local) will work if the server is on the local machine (the same machine the application is running on).
If it isn't local, there might be numerous instances of SQL Server running on the user's network. If you don't know the name of their server, how would you know which one to connect to without asking the user? You could present them with a dialog box that allows them to choose one of those available, then save what they chose somewhere (registry, file, whatever) so you don't have to ask them again. Or, make this a part of your installation process. There are various ways of handling this issue.

Hi dadax!
Check my blog article at http://www.cubido.at/Blog/tabid/176/EntryID/34/Default.aspx. It describes how to do that using SQL Server's new encryption/decryption feature.

.net 2.0 or 1.1?
For basic code behind binding, you need a datareader, or dataset and then set
myRadio.DataSource = myDataSource
myRadio.DataTextField = "TextFieldInSource"
myRadio.DataValueField = "ValueFieldInSource"
myRadio.DataBind()

configuration:
server:
MySql 5.0.15-nt via tcp/ip
Client:
MySql Client Version 5.0.11
Operating system:
XP
Startup Variables:
Max Packet Size 1mb
Net Buffer Length 16k
I am using Inodb and the c/c++ api
Let me know if you need additional config info.
OK.
I have an app which scans documents and then stores them as a blob. The typical size of an image is around 22k.
During storage, the app batches about 100 of these images along with other information in structures in memory and then initiates a transaction and stores all 100, committing when finished.
This works as expected and the time to do this commit is a couple of seconds, anyway, it is fast enough that it is not an issue.
My problem is this:
When I go to retrieve a single image, it can take as long as 60 seconds. I've played around with this quite a lot and when monitoring the network, to see when the image is downloaded, the image appears to come down right away and then the statement hangs/waits for a timeout before returning... as long as 60 seconds.
The statement which hangs is the:
imageRes_set = mysql_store_result(m_mysqlConn);
QStr.Format("select Image from docimages where BatchNum = %s and ItemId = %s and Side = \"%c\"", BatchNum, ItemId, 'F');
mysql_query(m_mysqlConn, LPCSTR(QStr));
int ret = mysql_errno(m_mysqlConn);
if (mysql_errno(m_mysqlConn) != 0) {
str.Format("Error doing Preset Query 51 - %s\nFailure to do Select on Image", mysql_error(m_mysqlConn));
AfxMessageBox(str);
Close_Database_Connection();
return(false);
}
imageRes_set = mysql_store_result(m_mysqlConn);
row = mysql_fetch_row(imageRes_set);
if (row == NULL) {
Mess1.Format("************ The Image, in batch num (%s) does not exist in the Data Base ************\n\n ", BatchNum);
Mess2 = "\tIt is not possible to View and Key an non existing Image\n";
AfxMessageBox (Mess1 + Mess2, MB_OK | MB_APPLMODAL | MB_ICONQUESTION, 0 );
Close_Database_Connection();
return(false);
}
