I have solved an earlier problem which I posted here, about coding Data
Source in OleDbConnection - I am new to ASP.Net. I do not understand the
solution, I just blindly followed the book (Teach Yourself ASP.NET in 21
Days), and guessed, and it worked.
When OleDbConnection is used to connect to a database, ASP.NET appears to
expect a client source, not a Web server reference. I just coded
c:\WWWRoot\.... and it worked.
Does this mean that ASP.NET downloads a database, like HTML pages are
downloaded, and then uses the actual client? I find such a concept to be
unbelieveable, or does ASP.NET download only a database definition? In any
case it is dangerous to download anything to the client regarding a database
due to security.
I expected the Web server to handle the data query and only generated HTML,
including the data query or update message, to be downloaded to client, and
the client to have no knowledge about the database. Therefore, I find it
difficult to understand why a harddrive reference should be included
anywhere in database connection code.
Code: dbStr="c:wwwroo t\...", objConnection = New
OleDbConnection ("Provider=Micr osoft.Jet.OLEDB .4.0;" _
& " Data Source=" & dbStr & ";")
I would be grateful for any clarification on this?

Trevor Hi,
OleDBConnection class is part of the CLR classes and it can be used on
the SERVER side to generate HTML that will be sending to the client. So
the local path is the server local path. Neither the OLEDBConnection
will happened on the client machine nor the DB will be download to the
client.

Hi,
i have a problem about the CLIENT-SERVER architecture procedure.
Well , i have an application in VB with ADO connection to a table in a
database on a SQLSERVER 7.0 .
Is possible to do that when a client updates a data in a field of my table ,
the SERVER communicates to all clients connected to my table that this data
are updated , without the client do anything , for example without a
client-timer to control the data in the server ???...

Dear all,
here is a simple problem that I cannot overcome:
I'm trying to write a client/server application in Visual Basic .net. The
server is an executable (.exe) project, the clients are class library (.dll)
projects. The server loads the clients from their DLL-files at runtime using
reflection tools, such as:
ClientAssembly =
System.Reflection.Assembly.LoadFrom(Client_To_Load_File_Name)

Hello,
I'm new to Web Services.
I'm trying to develop a Web Service that retrieves some data out of a

My question is: Is it possible to run another method on the Web Service
automatically to refresh the data? That means the Web Service should interact
as a Windows Service after a certain amount of time it should retrieve the
data and stores them locally, and...

Hi,
I have an interesting problem. I have a (LARGE) set of historical data

The files are in binary format, to conserve space on the server (as well
as to increase processing time). The data in each file can be quite

Hello all,
This is my first attempt at an application, so kid gloves are
appreciated.
I need to make a very simple form that only has a few elements. One is
TraceCode - a text field that is populated when a user scans a label.
The other is ScanDate - a date/time field that should equal the
date/time of the scan (e.g. 7/31/2006 5:00:00 AM).

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
