every time when I opened the connection from my windows CE4.2 device to sql server I got the error "Can't find PInvoke DLL 'dbnetlib.dll'.
My OS is MS CE4.2, I've installed Compact Framework 2.0 and SQL client. It worked fine at OS CE5.0 but not at CE4.2. My application is working correctly, but when I started the connection I received this error.
Any idea?
thanks, Jan
Hi All,
I'm developing Pocket Pc application, In that i have set of statement, which establishes connection with sql Server 2000 Database. When ever I try to open SqlConnection, I€™m getting error "Can't find PInvoke DLL 'dbnetlib.dll'.". Right now i am working in .Net Compact Framework 2.0 , But previously i worked in .Net CF 1.1 i didn€™t face problem while doing that. Can any one help me to solve this issue?
My code exactly look like :
Private SqlCmd As New SqlCommand
Private SqlTrans As SqlTransaction
Private SqlConn As SqlClient.SqlConnection
Private SqlCmdBuilder As SqlCommandBuilder
Private SqlDataAdapter As SqlDataAdapter
Public Function Select_DocumentTemplate() As DataSetDocumentTemplate
Dim DocuMentTemplateDs As New DataSetDocumentTemplate
Try
SqlConn = New SqlConnection("Data Source=SERVERNAME;Initial Catalog=DATABASENAME;Persist Security Info=True;User ID=sa")
If SqlConn.State = ConnectionState.Closed Then
SqlConn.Open()
End If
SqlCmd = New SqlCommand
SqlCmd.CommandType = CommandType.StoredProcedure
SqlCmd.CommandText = New StringBuilder(500).Append("Select_documentTemplateDetails").ToString()
SqlCmd.Connection = SqlConn
SqlDataAdapter = New SqlDataAdapter(SqlCmd)
SqlCmdBuilder = New SqlCommandBuilder(SqlDataAdapter)
SqlDataAdapter.Fill(DocuMentTemplateDs.Ncm_DocumentTemplate)
Return DocuMentTemplateDs
Catch ex As Exception
Throw ex
Finally
SqlConn.Close()
End Try
End Function
' When Ever I try to call above method to retrive data from Db , It's giving Missingmethod Exception and error message will be "Can't find PInvoke DLL 'dbnetlib.dll'."

I ge the error message: Cannot find PInvoke DLL SqlCeMe30.dll
I found such dll to be located in:C:Program FilesMicrosoft SQL Server 2005 Mobile EditionDeviceMobilev3.0wce500x86 among other folders.
Why then is "not found"?
I am using an O2 XDA II mini running Windows Mobile 2003 SE. Tried creating a Windows Mobile 5.0 Pocket PC project but during deployment, I get this error.
Can't find PInvoke sqlceme30.dll
I have searched thru the forums and found something similar. I tried all their recommendations but no luck. Is there anything I am doing wrong? I copied the DLL files in the device's Windows directory (sqlceme30.dll, sql*.dll...around 5 DLLs)
I would appreciate any assistance

I have two apps, with the same code on both app :
Dim ConnStrToServer As String = "Data Source=myIP,1433;Initial Catalog=mydatabase;User ID=sa;Password=;"
Dim connection As New SqlConnection(ConnStrToServer)
connection.Close()
MsgBox("This will take a minute")
Try
connection.Open() -->> ERROR!!
Dim queryString As String = _
"Update mytable set flag='PESAN'" & _
", username='" & tbIdNumber.Text.Trim & "'" & _
", tglpenyerahan='" & Now & "'" & _
" Where KodeProyek='" & kodeProyek.Trim & "' And NoKavling='" & NoKavling.Trim & "'"
Dim adapter As SqlDataAdapter = New SqlDataAdapter( _
queryString, connection)
Dim mstmap As New DataSet
adapter.Fill(mstmap, "mytable")
connection.Close()
Catch ex As Exception
MsgBox(ex.Message)
End Try
the different is the first app is a SQL Mobile app, now when I try to open a connection from the first app is always shows that error with the above code (eventhough my replication not error), but when I try to execute (success open connection) the query with the second app (not SQL Mobile app) works!

SQL Server is running on my PC. The server name is 'ASPEN'. When I create a DTS package to export a local database to our live site, I must use 'LOCAL' for the server name, not 'ASPEN'. Everything runs fine the first time, but later, when I try to execute, or even view, the local package I saved, I get the following error:
[DBNETLIB][ConnectionOpen(Connect()).]SQL Server does not exist or access denied.
Can anyone explain this?

I have checked around and found two potential fixes for this problem. The first one describes this as a problem specific to the Named Pipes protocol. The fix is listed as available from this site:
http://support.microsoft.com/default.aspx?scid=kb;en-us;827452
The second fix is listed as making an additional entry to the registry like this:
The problem arises on a busy SQL system and some requests will randomly seem
to be dropped with a General Network Error.
To fix:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServic esTcpipParameters
Add a new DWORD key SynAttackProtect with value of 0. Restart server.
Can someone tell me if either or both of these approaches is correct?
We have a Dell 2950 running Windows 2003 connecting to SQL2005 Database.
Users accessing their SQL application are getting this error message after leaving the application open for a period when they are not accessing the system. We have run the application on two different servers and cannot re-create the errors, which might suggest a hardware problem with our server, but as yet we haven't identified the problem.
Does anyone have any ideas ?
Hi All,
I have application desinged using VB.Net and sql server 2005. Its been deployed at remote site which is connected to my database server using VPN.
There are 2 machine at the remote site. One machine is working perfectly with all the reports and forms working. second machine is having problem runing one report. Reports is based on View which around 8 tables joined.
It shows the following eror

Hi,
I have a classic ASP app that loops through a record set and calls another query based on each record returned. Something like:
sSql = User Query
rsUser = conn.execute(sSql)
do while not rsUser.eof
sSql = Select [Type] From [User Types Display] Where UserId = rsUser(€œUserid€?)
rsType = conn.execute(sSql)
€˜ Put information into HTML table
rsType.Close
rsUser.MoveNext
loop
In general, at around 3575-4000 loops, the system kicks back :
Microsoft OLE DB Provider for SQL Server error '80004005'
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.
UserList.asp Line 300
I get no error message in the SQL Server Logs (according to the server, nothing happened), just this message on my ASP page. This happens about 90% of the time. 5% it runs completely, the other 5% bombs after 1-100 loops.
This only started happening when we took our app from a local Server 2000/SQL 2000 setup to separate Server 2003/SQL 2005 setup.
In SQL Profiler I see the loops hitting with only two reads per batch (TCP/IP). This seems very low compared to named pipes (when in a local server configuration) reads of 15-30 reads per batch.
I know it is not a hardware issue; this behavior is observed in both our test and production environments. All of our other ASP page queries work fine, just the 2 or 3 of hundreds that loop like above. cause the error.
Client Details (as best I could):
Connection String (in .inc file): conn.Open "Provider=SQLOLEDB;Network=DBMSSOCN;Data Source=10.0.1.100;Initial Catalog=€™TestDB';User ID='XXXX';Password='XXXX'"
The Client is Remote to the SQL machine and connects through TCP/IP only.
I force no encryption on the back and forth between the servers.
Server Details:
SQL Server 2005 Standard with SP1
Only Named Pipes and TCP/IP are enabled
I think this is all the info relative to my issue.
Thank you so much for any help,Smith

Hi,
I am trying to set up Transactional replication with immediate
updation.
The configuration is as follows:
1. Publisher is SQL server 2000 Enterprise Edition, and Distributor is
on the same server.
2. Publisher SQL server Standard Edition is installed on Windows 2003 with sp1.
3. Subscriber is an SQLServer 2000 Evaluation version on Windows
Professional 2000 with sp2.
When I set up the Publisher with transactional replication with
immediate updation only, the set up was successful.
I subscribed 2 instances of SQL server from Windows 2000 professional
on the local LAN in the same domain. The set up went fine.
When I update from the publisher end the updation is successfully
replicating to all the subscribers. But when I try to insert any
records in any one of the subscribers, I am getting the following
error:
[Microsoft] [ODBC SQL Server Driver ][SQL Server
][DBNETLIB][ConnectionOpen(Connect()).] SQL Server does not exists or
access denied.
I am beginner to this replication technology, but I have to set up in
my organisation. Please anybody help me in figuring out the actual
problem and resolving it.
Thanks in advance.

My program connected to SqlServer when it started, the state of the connectionPtr was adoStateOpen.Then I disable the network card and enable it immeditately, the errors happened when I executed the sql query probably because of connectionPtr was invalid,but the state of connectionPtr was always adoStateOpen.

Hi,
in our environment
- Windows XP
- SQL Server Express 2005
- Internet connection via TCP/IP protocol
The described network error occurs, when we unplug the network cable:
[DBNETLIB][ConnectionWrite (send()).] General network error.
The affected database resides on the locally installed SQLExpress, it doesn't use any network connections. The error doesn't occur immediately, in most cases there are up to 30 seconds where data can be (correctly!) written to the recordset, but after that timeout the connetion is broken.
We already tried out the described workarounds:
- disable named pipes protocol
- set SynAttackProtect=0 in HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters
The error doesn't occur with MSDE (SQL 2000) or under Vista.
Thanks for help!

tested my connection via ODBC, or SQL Query Analyzer just fine so I
know the userid/password is correct.
this is the snipplet code from the aspx.vb code-behind file:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _

Dim dbConn As OleDbConnection
Dim dCmd As OleDbCommand
Dim dReader As OleDbDataReader
Dim strConnection As String
Dim strSQL As String
If (Not Page.IsPostBack) Then
Try
'get the connection string from web.config and open a connection
'to the database
strConnection = ConfigurationSettings.AppSettings("dbConnectionString")
dbConn = New OleDb.OleDbConnection(strConnection)
dbConn.Open()
'build the query string and get the data from the database
strSQL = "SELECT Title, ISBN, Publisher " & _
"FROM Book " & _
"ORDER BY Title"
dCmd = New OleDbCommand(strSQL, dbConn)
dReader = dCmd.ExecuteReader()
'set the source of the data for the datagrid control and bind it
dgQuick.DataSource = dReader
dgQuick.DataBind()
Finally
'cleanup

dReader.Close()
End If
If (Not IsNothing(dbConn)) Then
dbConn.Close()

this is the connection string inside the web.config file:

Hi have created an application in asp.net to connect to a sql database.

How do I know if SQL server is installed on my system? cuz in my systray I see SQL server service manager, is that the same thing as SQL server? or do I need to download the full version or something? also could it be that a certain port on my system is not open that SQL server requires to be open?

Hi Folks,
Lets get this out of the way first - I KNOW NOTHING ABOUT SQL SERVER, MSDE or MDAC
Sorry I don't mean to shout but I really don't know anything at all so please make your answers as simple as possible.
I have an application (Webmarshall) that has a SQL database from which certain reports are run. Whenever I try to run the reports it asks me for database details.
According to the application it is using LANCELOTWEBMARSHALLWebmarshall as the database
As this is all happening on one server, I presume it is local and not remote.
When I am presented with the dialogue box for the reporting module it asks for a server and a database, I have tried the following :
Server: local Auth: Windows
Server: local Auth: SQL
Server lancelot (both authorisation methods)
Server: lancelotwebmarshall (both authorisation methods)
Server: \lancelotwebmarshall (both authorisation methods)
Each time, I get the message
[DBNETLIB][ConnectionOpen(Connect()).]SQL Server does not exist or access denied
and I can't select a database.
Can someone help me please...its a long time since I went fishing in the dark (with no net) but thats how I feel right now!!!!
Thanks
Hello together,
since over a week I've been looking to
find out the reason for two error messages I get from our users and
servers, unfortunately without success up to now.
I really hope you can help me.
We are using Win 2k servers with active directory and SQL Server 2000,
clients are all Win XP with SP2. Versions of access are 2002 &
2003. The errors are userspecific and occur in both versions. The
SQL-Servers are accessed with an adp-file in 2002-format.
We have one usergroup which is member of specially many groups. This
affects the size of their windows access token which becomes constantly
larger. In order to enable those users to still access their mailboxes
on our Exchange servers, the DWORD entry "MaxTokenSize" with the
decimal value "65535" was made to the newly created key "Parameters" of
their registry branch
"HKLMSYSTEMCurrentControlSetControlLsaKerberos ".
Since then those users can not access any of our SQL Servers using the
windows authentification. One of them gets the error
"[DBNETLIB][ConnectionRead(recv().] General network error. Check your
network documentation.", the others the error "Check connection:
Failed: Cannot generate SSPI context".
In case of resetting the registry entries (by deleting them), the one
user receives the same error message as the rest while it doesn't make
any difference to those (but at least they can't connect to their
mailboxes).
After having researched the web, I realised in one of the SQL-Servers
logfiles the entry "Invalid buffer received from client.." which lead
me to start to believe it could have to do something with the kerberos
encryption in the first place. Therefore I asked if changes to the
tokensize had been made. I applied the change with "EXEC sp_configure
'network packet size', 65535 RECONFIGURE" on our testsystem and "EXEC
sp_configure" confirms that the value is run.
Consequence: The entry in the SQL Server log doesn't appear any longer, but the users still receive their error messages.
Do you have any hints?
Your comments will be highly appreciated!
Regards,
caracol
I installed SQL 2005 including backward compatibility, MSDN libraries and SP2 a new Windows 2003 server (chose mixed mode authentication). Installation was successful and I then installed an off the shelf database with Windows authentication which also installed successfully.
I created a new group in AD, added the database users into the group and gave db-owner rights to the group in SQL as advised by the installation guide. However, when I try to open the database it gives an error message saying "Cannot open database.[DBNETLIB][ConnectionOpen(Connect()).] SQL server does not exist or access denied". I also tested it adding an individual user (myself) as a user to no avail.
When I set up DSN in ODBC on my computer I can successfully test the connection but can't run the application. The connection is via TCP/IP.
Any suggestions?
