Can I Access My Private Db Through My Web Server?
Aug 30, 2005
Web server: win2003 server with iis6
DB: sql server 2000
I have 50+ remote offices running an Access 2002 app which connects
directly to sql server at a 3rd party hosting company, in part using an
odbc connection on the workstation.
We recently moved our database (and our web site) in-house. The new
database is inside the firewall but outside the dmz, where it lives
along side the company's most sensitive databases. IT's policy won't
allow us to connect directly from the internet. I'm trying to avoid
buying another copy of sql server for the Access app, which I one day
hope to drop anyway in favor of
The web server uses port 1433 to talk to the database. I was wondering
if there is a simple way to route requests from the Access app through
the web server.
Thanks,
Bob

I've just bought a Virtual Private Server Account because I want to host a number of different ASP.NET sites, each backed by their own SQL database. I've downloaded SQLEXPRE.EXE and SQLServer2005_SSMEE-x64.msi to the server and installed the database engine and Management Studio Express on the VPS.
My problem is that I cannot access the SQLEXPRESS on my server from my local machine. The Management Studio Express cannot get logged in. I've used "Surface Area Configuration Manager" to allow "Local and remote connections" using TCP/IP only. I've used SQL Server Configuration Manager" to enable the TCP/IP protocol. After making these changes I've stopped and started the SQL server - and even rebooted the machine. I've created a login "Remote User" for this access. I've added sqlservr.exe as an exception to the firewall.
What else do I need to do? Is there a simpleton's guide to completing this task?

We are planning to encrypt few fields using asymmetric encryption. Tyring share public key with users and retain private key with us. How to generate keys? Haven't found any solid document on how to generate these keys.

hey,
i have a problem, to import a self signed openssl certificate into the sql server 2005.
my final idea is to get encrypted columns from the database over an jdbc connection in a java client.
when i use a certificate generated by the sql server 2005, i can encryt columns of a table. then i catch the
the result in my java client. but in java, i need a keystore with the private key of the certificate.
ok. i have export the the certificate and the private key of the sql server 2005.
problem: in a keystore i can only import the certificate (signed public key) but not the private key.
my new idea is to import an openssl certificate or an certificate generated by the keytool (java) into the
sql server 2005 and encypt the data with the imported certificate. Problem: The SQL Server give me an
Exception: (Sorry i drag & drop the exception, is written in german)
Msg 15208, Level 16, State 1, Line 2
Die Datei für das Zertifikat, den asymmetrischen Schlüssel oder den privaten Schlüssel ist nicht vorhanden oder weist ein ungültiges Format auf.
My Import Statement is:
CREATE CERTIFICATE InsuranceCertOpenSSL
FROM
FILE = 'E:masterkeysinsuranceservice_tomcat_apr_x509_certificate_with_cygwin_openssl_20060630insuranceservice_tomcat_x509_certificate_with_openssl.crt'
WITH PRIVATE KEY (
FILE = 'E:masterkeysinsuranceservice_tomcat_apr_x509_certificate_with_cygwin_openssl_20060630insuranceservice_tomcat_x509_certificate_with_openssl_private.key',
DECRYPTION BY PASSWORD = 'testit2_',
ENCRYPTION BY PASSWORD = 'testit2_'
)
I use password encryption, and not the internal master key (or service master key)
Hope for help :)

I'm green on this networking stuff so any help is greatly appreciated.
I have setup my home computer as a server and assigned a static IP to it. I installed SQL Server 2005 Developer and allowed remote connections to it through the Surface Area Config tool, added port 1433 TCP and 1434 UDP to firewall's exception list, and started the SQL Server Browser service.
Now I can't seem to remote connect to this SQL Server from my office network. Is there something I'm doing wrong here?
Thanks!!

Hello,I have a doubt. I've just bought a private server and now I can decide between having my applications under a private SQL Server Express database or under a Shared SQL Server database.The application is not professional, it's just a hobby, but it could have more than 100.000 entries and be used by 200 users at the same time.I know the limitations of SQL Server Express, but I want to know the opinion of someone who have experienced about this.Thanks!

Hi
I am trying to setup service broker by following the article on http://support.microsoft.com/default.aspx/kb/915852
The script ran without error, but when I try to send a message, I get the following in the trace Audit Broker Conversation and the message is not delivered.
The certificate's private key cannot be found
This message could not be delivered because the security context could not be retrieved.
Does anyone know what I did wrong, is it the Certficate in the Master Database or the Target Database
thanks

One of our clients controls data for about 150 companies. Each company has the same schema and is running SQL Server 7. The maintenence task is horrible. He would like to put all the data in one large database, but needs to control the access, so a user at one company selecting data in a table cannot have access to another company's data in the same table. I thought about using views for each company but that is 150 companies times 100 tables. With Oracle8i you can make virtual private databases. Can this be done in SQL Server 7? Thanks in advance

I set up Service broker (2008R2 -> 2012) across different servers and domains using certificates.I set up 2 queues (one for sending, one for receiving).I set up 6 services (3 for send, 3 for receive), all 3 sharing the same queue type. (srv_send_1, srv_send_2, srv_send_3), (srv_receive_1, srv_receive_2, srv_receive_3).I set up a route for each receiving service on the source, and for each sending service on the target.I set up a SB binding to the remote for each sender service type.I granted send rights to the sending services on the source server.
I then tested my first service, and it worked perfectly (still works).My second service however is failing with the error "The certificate's private key cannot be found".I am stumped, as all the setup code was a lot of copy/paste which I have checked, rechecked and even re-coded.Basically, here is what Im doing:
begin dialog @ConversationHandle
FROM Service srv_send_1
TO Service 'srv_receive_1'
ON CONTRACT myContract
WITH ENCRYPTION = OFF, LIFETIME = 60*60*24*7;
SEND ON CONVERSATION @conversationHandle
MESSAGE TYPE [my_msgtype] (@xml);
The above code works 100% with service1, but not with service2.Note that on profiler, the target server doesnt receive any communication. The error shows on the sender profiler.Also, The conversation shows up as CONVERSING in sys.conversation_endpoints and the entry exists in sys.transmission_queue.

I have a couple of questions on the nature of shared and private deployment of SQL Server CE 2005 on mobile devices:
1. I've read that with a shared install, SQL Server 2005 Compact Edition files are automatically updated and serviced by Microsoft Update. I take it that this only applies to installations on desktop computers -- if you're installing on mobile devices, there IS no automatic update. Right?
2. I've also read that in order to do a shared install of SQL Server 2005 CE, the user must have administrative rights. How does this apply to installs on a mobile device? There is no such thing as an administrative user on a mobile device. However, mobile devices CAN require different levels of privilege to install certain programs -- do you need something like an application signed for privileged execution (via a M2M certificate) in order to do a shared install of SQL Server 2005 CE on a mobile device?
Or is the shared versus private deployment only an issue when deploying to a desktop?

MSDN has examples of deploying SQLCE privately for C# and VB.NET, but that doesn't seem to translate to C++. A .NET application just loads the assembly it needs from the local directory, but from what I can tell I need to use the OLE DB driver to use SQL CE in C++. The problem is that the OLE DB driver is a COM object that (presumably) needs to be registered.
Has anyone successfully used SQLCE from C++ without registering any COM objects? I'm thinking the only way to do that would be to call DllGetObject() on the DLL and get the object manually, but I've never done this so I'd hate to waste the time if there's an easier way, or if this won't work.

We are looking to put column level encryption on a table. Great! Wonderful! Look in books online and see that you must give "control" perm to the Certificate for any user that needs to use the symmetric key.
Now my question. I have backed up the Certificate to file. What I have found playing around with the commands is it is possible to run the following command:
Alter Certificate MyCert
Remove private key
BOL says their is no "Restore Certificate" command and to just use "Create Certificate". I have tried this and I keep getting an error saying the certificate already exist in the database.
What have I missed? How can I restore this certificate without restoring the ENTIRE database? Is there a permission set that can be applied to the Certificate to stop thsi kind of command from being run while still having the symmetric key usable? Any help would be of great use!
Thanks,
*note* this is using the MasterKey->Cert->SymmetricKey

Is there any harm in defining a SqlConnection as a private class variable for a web page?Private SqlConnection cn = new SqlConnectection(ConfigurationManager.ConnectionStrings["MyString"].ConectionString);The connection is only opened in certain event handlers, and is closed right after use. It was always my understanding that creating the connection is not a big deal but opening the connection is. Is that correct?

I'm working on a VB.Net 2005 application that uses SQLCE as a backend database.
Following the instructions on how to do a private installation (http://msdn2.microsoft.com/en-us/library/bb219482.aspx) so that admin rights were not needed, I successfully got it working as a ClickOnce deployment. But today during a demo for a client, they ran into this error while installing the latest version from our publishing URL:
"Unable to install or run the application. Application requires that assembly System.Data.SQLServerCe version 9.0.42 .... must be installed in the Global Assembly Cache."
Basically it's saying the user isn't an admin so they can't install. This is the problem I went to great lengths to try to avoid, and is the reason we are using SQL CE in the first place: admin rights are not required to install our application's database. To our knowledge, SQL CE is the only Microsoft product that fits this scenario.
Now, I haven't changed anything in the publishing of the application to my knowledge, and when I check the project prerequisites, the SQLCE engine still isn't in there (as summarized at the above URL). Again following the instructions at the URL above for private installation, the required assemblies are still part of the project's files.
It must be something I did to cause this, but I have no memory of changing anything in regards to this part of the application. Our deadline is in 4 days and I cannot continue development until I get past this issue.
Where do I look to fix this problem? A little help would be greatly appreciated.

Here is what I am trying to do. I want to create a private / public key pair (either a certificate or asymmetric key) and be able to give the public key to my business contacts. They would then use the public key to encrypt data to be sent to me and then I could import that data into my SQL 2005 database and use the private key to decrypt it.
It seems to me that this should be a pretty simple process, but it is not. The reason I want to do this is that the data they send to me on a regular basis is sensitive. Currently we use PGP, but then I have to decrypt the data and then import it and then reencrypt it. It would greatly simplify my process if I could just import the data and use it.
So how can I do this. Most of the posts I read say that asymmetric keys are avaiable in SQL2005 but not recommended for use. I don't want my business contacts to be able to decrypt any of my data (if they got access to the database) just encrypt.
Any recommendations???
Thanks!

Folks- By reading all the results I got from doing a search on "private install" in this forum, I thought this must be as easy as:
1. Copying the seven DLL's comprising the engine to my application's install dir on the deployment machine. If my app is installed at C:MyApp then CE dll's would go into C:MyApp, thats where my WinMain'd exe is residing.
2. RegSvr32 on sqlceca35.dll, sqlceoledb35.dll
Since I'm using native C++/OLE DB, I don't think I'd need to care about System.Data.SqlServerCe.dll
However my app which is basically the NorthWnd sample is failing on CoCreateInstance(CLSID_SQLSERVERCE_3_0............)
Which means oledb provider not registered on the machine? am I correct?
I watched Steve Lasker's video, even though the private install covers managed code, but I thought I should be doing something very similar, apparently I'm missing something.
I'll appreciate any help.
P.S., The 7 dll's above I mentioned are:
sqlceca35.dll
sqlcecompact35.dll
sqlceer35EN.dll
sqlceme35.dll
sqlceoledb35.dll
sqlceqp35.dll
sqlcese35.dll

Hi Guys, I've got a bit stuck trying to decide on a table structure for a private message like part of a site I'm building (I'm using SqlServer 2000, not that it really matters).at first I was going to use a single table with the following schema: MessageId intReplyToMessageId int (nullable)FromUserId uniqueidentifier (I'm using .net membership)ToUserId uniqueidentifier IsRead bitIsDeleted bitSubject nchar(50)Body nvarchar(1000) DateCreated datetimeDateUpdated datetimeCreatedBy uniqueidentifierModifiedBy uniqueidentifier What strikes me here is that I'm using alot of guids (which are huge) and if I'm going to be threading the messages (which I am) there's no easy way to return an ordered list of messages that are replies to each other. So then I thought about introducting a messageThreads table, but I can't think of anything to store there apart from a threadid (which seems to defeat the purpose)Any ideas? I can clarify more if necessary. Thanks

SQL 2005 Standard x64 Service Pack 2
Windows 2003 R2 X64 service pack 2
The principle, partner and witnesss have two NICs each (NIC1 and NIC2). I want them to communicate in NIC2 for sending logs and establishing quorum. This will happen in their own private network (say 192.168.1.0/24). The NIC1 in each server will be available for client communication. The domain and clients are in the network (say 10.1.1.0/24).
I am using the same domain account as SQL server service account in all three servers.
How can I do this?

Hi, I am using express database and tools. I have an aspnetdb express database because I am using the login controls, personalisation...Can I use this database for my private tables also? Or do I need a separate express database for my private tables? Will using aspnetdb database, which contains special asp.net tables, for my private website tables create any kinds of problems in using my website? I want to use a single express database for my website, not two different express databases.

I am trying to create an assembly object when a report is initialized and I am getting the error:
[rsCompilerErrorInExpression] The BackgroundColor expression for the textbox 'textbox2' contains an error: [BC30390] 'ReportExprHostImpl.CustomCodeProxy.X' is not accessible in this context because it is 'Private'
In the Code tab, I have:
Dim X As namespace.classname
Protected Overrides Sub OnInit()
X = new namespace.classname()
End Sub
In my color field, I have "=code.X.color"
If I replace the color field with "=namespace.classname.color" and have color be a shared property, then it works. However, I ultimately need the color to be based on individual user settings, so I cannot use the shared property approach.
Any ideas on how to get around this "because it is private" error?
FYI, I am trying to replicate the concept of themes using report formatting information pulled from a database.

I am trying to convert a certificate that was exported from our database server to be used by SQL Server for database encryption. When I run the PVKConverter, not Private Key File (PVK) is generated.The certificate has Server and Client Authentication as the purposes of the certificate.
What purpose or purposes does the certificate need in order to be able to be used by SQL Server 2012 SP2?Why doesn't the PVKConverter generate a private key file?I can use the command makecerts to generate a self signed certificate and have it work with SQL Server database encryption.

I have recently upgraded to SQL2014 on Win2012. The Access front end program works fine.
But, previously created Excel reports with built in MS Queries now fail with the above error for users with MS 2013. The queries still work for users still using MS 2007.
I also cannot create any new queries and get the same error message. If I log on as myself on the domain to another PC with 2007 installed it works fine, so I don't think it is anything to do with AD groups or permissions.

Hi guys,
I've been developing desktop client-server and web apps and have used Access and SQL Server Standard most of the time.
I'm looking into using SQL CE, and had a few questions that I can't seem to get a clear picture on:
- The documentation for CE says that it supports 256 simultaneous connections and offers the Isolation levels, Transactions, Locking, etc with a 4GB DB. But most people say that CE is strictly a single-user DB and should not be used as a DB Server.
Could CE be extended for use as a multi-user DB Server by creating a custom server such as a .NET Remoting Server hosted through a Windows Service (or any other custom host) on a machine whereby the CE DB would run in-process with this server on the machine which would then be accessed by multiple users from multiple machines??
Clients PCs -> Server PC hosting Remoting Service -> ADO.NET -> SQL CE
- and further more can we use Enterprise Services (Serviced Components) to connect to SQL CE and further extend this model to offer a pure high-quality DB Server?
Clients PCs -> Server PC hosting Remoting Service -> Enterprise Services -> ADO.NET -> SQL CE
Seems quite doable to me, but I may be wrong..please let me know either ways
Thanks,
CP

Hi,
A long time ago I posted this: http://blogs.conchango.com/jamiethomson/archive/2005/06/09/1583.aspx explaining all the different buffer types in the pipeline.
I have to admit I'm still not clear on the difference between a private buffer and a flat buffer though.
Are flat buffers a subset of private buffers.
If so, if a private buffer is not a flat buffer - what is it?
If not, can a buffer be a private buffer AND a flat buffer?
Some descriptions from BOL are:
Private buffers: A private buffer is a buffer that a transformation uses for temporary work only
Flat buffers: Flat buffers are blocks of memory that a component uses to store data
That sounds like two ways of saying the same thing to me! It certainly doesn't distinguish them anyway!
Just seeking some clarification here. If you could whip of a demo package that explains the difference between the two (with reference to the Performance Counters) then that would be great.
Thanks
Jamie
