Hi Friends,

I am working in vb2005.
I have been struck up in my work while retrieving the computer information in a active directory . Frown | :(

This is the code I am using,

<br />
dim np as object<br />
np = GetObject("LDAP:")<br />
dim user as object <br />
user = np.OpenDSObject( LDAPPath , vbNullString, vbNullString, ActiveDs.__MIDL___MIDL_itf_ads_0000_0018.ADS_SECURE_AUTHENTICATION)<br />

This code is working well while retrieving person data ,but when it comes to computer
it is throwing the following message .
The specified directory service attribute or value does not exist. (Exception from HRESULT: 0x8007200A)
The LDAPPath that had passed is correct one.But still getting the error.

Please help me out to solve this problem.Thanks in advance .

Regards,
Chaitanya

Conection to SQLExpress Server

I added Database file in VS2005 project. and this is the connection string i am using

"Server=.\SQLExpress;AttachDbFilename=|DataDirectory|mydbfile.mdf; Database=dbname;Trusted_Connection=Yes"

It works fine since database file and application is on local system. But when i try to connect to remote database by providing the IP address i get this error

"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP Provider, error: 0 - No connection could be made because the target machine actively refused it.)"

How can i make connection with Remote instance of database file located in the data directory, on remote SQL Server Express instance

The most common cause for this error message is found in the error message:

"When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections."

Verify that the database that you are connecting to is set up to accept remote connections.

I have enabled the remote connection also. but it is still giving me the error.
this is the connection string i am using. is this correct?

Server=IP\SQLEXPRESS;Database=Database;Trusted_Connection=yes;

A trusted connection only works if you have a domain account, so that it's the same account on both computers. Otherwise you have to use an SQL Server login.

This can be done only if we have SQL express edition instaled. But if i am using mdf in the project like in VS 2005 then i need to connect to another mdf file on network

Hello,

So you basically wants to move the XML data into the SQL server. If you are trying to do
this through code, then you can have a look at the given web link which should give you
some fair idea on how to achieve this.

Hope this will help.

hi Allen,

Thanks for your suggestion.I think it will work if i create related table first. But i do not want to create table by myself.i want something dynamically to store it from dataset to database.

Hope you help me again.

You just need to issue a create table statement first, surely...

you can insert xml file directly to sql server.

for this you can see How to insert XML data in sql server database through visual basic .net

may be you have to work through it if you got big xml but it is very handy way of getting your xml data in database.

Keeping socket connections alive

Mariano Capezzani30-Sep-08 9:07

Hi all,

I have a server application awaiting incoming connections through a series of sockets set in "listen" mode. I have a number of client applications in remote locations that communicate via tcp/ip, opening the corresponding socket connection to the server and transmitting data.

The problem I have is that the client-to-server socket connections seem to die out after a while, specially in locations where internet is intermittent. When this happens, the connection does not terminate, rather it stays in "connected" state, but data transfer is lost in the web. Even though the winsock.state = sckConnected, the data is not received.

In order to solve this, I implemented a refresh timer, that closes and reopens all sockets in the server once every n seconds. It works, but it's terribly unelegant. I have found no other way of doing this, keeping the connections alive.

Anybody could please give me a suggestion on how this can be done properly? How can I determine if a connection is alive or dead, regardless of what .state says?

Thanks,
Regards.

are you using win sock . I had the similar problem before using win sock where i lost data even the client was connected with the server.

But later i used dart sock and it helped me you can get the trial version of these from www.dart.com and try it out, hope this would help you.

Yes, I use winsock. Thanks for the tip!!, but I think I might have solved temporally in a rather clumsy way.

I set up each client to "ping" the server every second. The server "pongs" to each "ping". I there is no "pong", the connection is down and a reconnect is issued. This check is performed at both sides.

Unelegant, but it works, and it´s free...

Has anybody implemented a different type of "keep alive" mecanism?

DataAdaptor Update Error

I am getting ORA-01036 (Illegal Variable Name/Number) when I call the oracledataadaptor.update method.

I am able to fill the dataset & bind to the datagridview. When I try to update Oracle with the dataadaptor,
I get the Illegal Variable name exception.

Any ideas?

Thanks in advance!

' '' ''' '''' Call the update method

Try
daCustomers.Update(ds.Tables("Customers"))
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try

' '' ''' '''' Set up Oracle Update Command
Private Sub SetCommands()

Dim uCMD As New OracleCommand
uCMD.Connection = cnOra
uCMD.CommandType = CommandType.Text
uCMD.Parameters.Add("@inFNAME", OracleType.Char, 30, "FNAME")
uCMD.Parameters.Add("@inID", OracleType.Int32, 12, "ID")

uCMD.CommandText = "Update NYOUG_CUSTOMERS SET FNAME = @inFNAME WHERE ID = @inID"
daCustomers.UpdateCommand = uCMD
End Sub

The syntax of bind variables depends on the connection type you use. Try using : instead of @. For example:

kermit888 wrote:
uCMD.CommandText = "Update NYOUG_CUSTOMERS SET FNAME = @inFNAME WHERE ID = @inID"

uCMD.CommandText = "Update NYOUG_CUSTOMERS SET FNAME = :inFNAME WHERE ID = :inID"

The need to optimize rises from a bad design

I tried switching the "@" with ":" but got the same result.

Did you also replace it in parameters. You could also try without semicolon and perhaps with less info to the constructor. Meaning, try both variations:

uCMD.Parameters.Add(":inFNAME", OracleType.Char, 30)
uCMD.Parameters.Add(":inID", OracleType.Int32)

and

uCMD.Parameters.Add("inFNAME", OracleType.Char, 30)
uCMD.Parameters.Add("inID", OracleType.Int32)

Problems with Flash content viewing in Web Browser Control

I'm having problems using the Web Browser control in Vista. When I go to a page with any type of Flash Content it won't load. I went to the Flash plugin page and it said 64bit web browsers are not supported. This only happens on the Web Browser Control that I am programming with. If I just open the Microsoft Internet Explorer 7 it works just fine and has no problem loading Flash content. If I can't display Flash content it's a big problem so if anybody can point me in the right direction it would surely make my day.

Thanks In Advance

PS I have tried both the com version and the one that comes with VB.Net
both will not display Flash Content

I am using Vb.Net 2008 Express
Operating System Vista Home Premium Service Pack 1
