Difference Between SQL Server Native Client And SQL Server DSN To Support SP Execution?

Jul 9, 2009

I wrote a VB code to call a sp in sql server 2005, which returns a recordset as follows:Dim objRecordset As ADODB.Recordset Set objComm = New ADODB.Command

Set objRecordset = objComm.Execute If Not objRecordset.BOF And Not objRecordset.EOF Then
Set objRecordset = objRecordset.NextRecordset I need to continue to get next recordset since there are many select statements inside the sp which I need to get the data. The code works fine when I create the DSN using SQL Server but it does not work when using the connection string or SQL Server Native Client DSN. It either breaks at Set objRecordset = objComm.Execute ( connection string )or at If Not objRecordset.BOF And Not objRecordset.EOF Then(SQL native client )

I have worked on this for a couple of days now and could not figure it out.Is this a bug in SQL Native Client or something related to some configuration on the database side? IS there a way I can change the connection property to get this working using SQL native client or connection string?

VS 2008 TCP Server / Client - Client To Send The Server 4 Numbers - Depending On The User's Choice

May 9, 2009

how to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])

Server/Client - Basic Tcp Server/client Application

Mar 30, 2009

I've basically made a basic tcp server/client application. The thing is that I'm behind a router and so will be the other people that use my clients. I've had to use port-forwarding or the software "rinetd"to run quite a few applications online.

Let me explain: I'm on a lan network that connects to the internet. Whenever I want to host a server - for instance a basic ftp or http server. If I give my external IP to anyone, they won't be able to access my server. Even if I portforward, it doesnt work. I have to use rinetd here. For other applications, portforwarding works. I'm not sure how these things work at all.

Anyway, my issue now is that I have created this server/client application. I'm having serious doubts that if I run the server, I'll have to either a) portforward or use rinetd to get people to connect to my server. IF I need to portforward, that's fine. However, using rinetd would really suck... My 2nd concern is as follows: IF the person running the client is in a similar situation as me (i.e he's on a lan that has a router which connects to the net), will he have to portforward or use rinetd as well? If he portforwards that's fine. But I don't think I could get people to use rinetd.... Also, if there are more than 1 person on a lan trying to connect to my server, there is a big problem when they try to portforward: they will only be able to allocate one of their internal ip to that port, and the others won't be able to connect, right? How does this work? I mean, I use many softwares like msn/skype/(some games)/firefox that do not need portforwarding/rinetd. Yet they work. My housemates(other people on the lan) use the same softwares, and it works fine. There's no clash/probs watsoever How come these run fine?

Anyway, back to my issues. Given I have no knowledge about how the above work, I was wondering whether there was a way to host a vb .net server application on an external website (external to my house) so that I might *avoid* the above mentioned problems, and to what extent that would be a sound solution.

Info: Multithreaded Server Socket Program Or Client/Server?

Oct 26, 2011

I made a simple TCP server (I've found the example on the web) in VB to receive data from about 40 TCP clients.The clients are not synchronized but sends data about every 18 minutes; the problem is sometimes several clients sends data at the same moment, so I can't receive data.I also made a second program that reads the data (server program writes data on a file, read from the second program) scheduled.

My question is this: I've seen on the web examples about Multithreaded Server Socket Program, so I suppose this could manage my 40 clients (but now the clients are syncronized and send data at the same time in client mode) or is better get data (I have a central client that asks data to all 40 devices in server mode)?

Second question: can I make a single program where I run both TCP client and TCP server at the same time?

TCP Client/Server App That Sorts Out Text That Is Recieved From Server?

Aug 18, 2011

I'm currently "trying" to make an app that gets a certain text from the client and sends it to a server and the server sorts it out every text that he gets from the client into a different label every time he gets a text from a client. For example :

Client1 sends certain text to Server and server puts it in label1.text
Client2 Sends different text to Server and server puts it in label2.text
Client3 sends different text than 1 and 2 to Server and server puts it in label3.text
and so on.

Client Needs To Have Sql Server On His Machine If Application Uses Sql Server?

Jul 16, 2009

I am creating small application (desktop search engine) which uses sql server as back end. Sql server is used to store huge data using indexing (for quick search). Is it necessary that client should have sql server on his machine to run the application? I don't want to install sql server on client's machine, because my application is just a small utility.Is there any other way so that I can store huge data using indexing?

Make Client Server Without Installing Sql Server?

Nov 6, 2009

I have an application in which i have a database .mdf file in directory which i use a connection string to give a path of to access it, which means without installing sql server i can access database. Connection string below to access this database(.mdf) which placed in the directory.

dim con as sqlconnection = New SqlConnection("Data Source=.SQLExpress;integrated security=true;attachdbfilename=|DataDirectory|Universal_data.mdf;user instance=true")

Now the question is that if i access this .mdf file without installing sql server, i also want to access to this .mdf file on other computer(client) after creating DSN or any other connectivity tool.

Let me know you that when i install sql server 2000 or 2005 i create SA user name and password which i use to create DSN on client computer and give SA username and password in the connection string that successfully works and client get access to sql server, connection string is below.

Dim serv = "MY-LAPTOP"
dim con as sqlconnection = new sqlconnection("Data Source=" & serv & ";Initial Catalog=clinic;Persist Security Info=True;User ID=sa")

I only need to know that my application access .mdf file without installing sql server works fine on a single computer, and i want to give access to this .mdf file on other clients without installing sql server on server computer (like i mentioned above paragraph) how will do it.....

Set The Timeout For The Execution Of A Set Of Statements When Using The SQL Server SMO Libraries?

Jul 25, 2011

I have the following bit of code that is timing out when I pass it a long running set of SQL statements. I'm using the Microsoft.SqlServer.Management.Smo library from SQL Server 2008.

Using cn As SqlConnection = GetConnection(_destinationCNS, True)
Dim smoServer As New Microsoft.SqlServer.Management.Smo.Server(New ServerConnection(cn))

[Code]....

I'm having trouble figuring out where to declare that timeout duration. What object and property should I be setting the timeout duration for the statement execution, not the connection timeout. On the SQLCommand object there is a convenient CommandTimeout property but I'm not seeing anything like that here.

Debugging Execution Of Database Function Call To Remote Sql Server?

Sep 14, 2011

Working in VWD 2010 Express I have an aspx.vb file with the following connection string:

Protected Function getPasswordLength() As Integer
Dim conn As New SqlConnection("Data Source=localhost;database=MyDB;Integrated Security=true")
Dim cmd As SqlCommand = conn.CreateCommand()

[code]....

This works when the code is on the web server / which is collocated with the SQLServer.However, when I want to debug, I have to copy to the server. I would like to be able to "debug in place" on my development machine and only copy files to the production machine periodically. Technically the production machine is not in production at the moment, but that's beside the point.Anyway, I followed the following instruction: [URL] I can now see the remote database, functions, etc. on the other machine (from the VWD running on the development machine). However, I thought I should then be able to execute this same code locally on the development machine using ctrl-F5, but I get the following error:

**Server Error in '/' Application.A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)**

Sql Server - SSRS Code Shared Variables And Simultaneous Report Execution?

Dec 28, 2009

I've found out that if two instances of an SSRS report run at the same time, any Code variables declared at the class level (not inside a function) can collide. I suspect this may be the cause of our report failures and I'm working up a potential fix.The reason we're using the Code portion of SSRS at all is for things like custom group and page header calculation. The code is called from expressions in TextBoxes and returns what the current label should be. The code needs to maintain state to remember what the last header value was in order return it when unknown or to store the new header value for reuse
