DB/Reporting :: Connect Database In Server From A Client Computer?

Feb 24, 2008

I wrote a program in VB2005. It is a program that is supposed to run in a client computer accessing an MS Access .mdb file stored in the server. The program itself is stored and run in the clients computer. I am not good in networking at all. The way I do it now is:

1. Have a directory made in the server to hold the MS Access .mdb file, and have the directory to be shared.

2. Have the same directory accessed and mapped in the client computer (say to Z:)

3. Then have the program in the client computer simply access the database as if it is in the same computer (as the directory already mapped into the client computer). In the VB 2005, this is done when we set the connection string of the database connection.

However, my user is complaining that by doing so, the database is basically exposed to the operator of the client computer (through the mapped directory), hence more vunerable for any bad intentions from persons who may have access to the client computer but not the server. He insists that he used to have a program that does exactly the same thing like my program, but the database is shielded in the server, where it cannot be seen in the client computer (I have other people who confirm that this can be done, though they can't tell me how, since they are not programmers themselves). Now, I have no idea on how to connect a database that way, and I don't even know where to start looking.

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.

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?

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?

Why Client Cannot Connect Remotely With External IP

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.

.Net Desktop Client Cant Connect To Offsite Webservice?

I have written a app that runs in multiple hospital networks. THe vb client periodically contacts a off-site webservice for datatransfers.The issue I am getting at a particular hospital is that the client PC's are not on the hospital's domain.  So they are sort of off the radar.  They do use the hospital network for internet access.  When the user opens a web browser they are asked for domain

userid and password.  If not are provided then they cannot proceed.  What do I need to do with my code to make the webserver calls prompt for and use the proper domain user id and password?

OP3 Client To Connect To Gmail And Download Messages

May 10, 2012

I am using Peter Huber's POP3 client to connect to gmail and download messages.The inboxes being accessed are transactional inboxes used only for code-access. That is, a message comes in with a order file attached, code will process it and then delete the message. One stipulation of the code though was a DEBUG flag, which if set would prevent the code from deleting the message so that you can run the program again later without the debug flag and reprocess the message. So, in my code I have If Not Arguments.Debug Then pop.DeleteEmail(eid)

This works fine. Problem is, even when not deleting the message, running the program a second time will not re-retrieve the message, even though if I login to gmail and look at the inbox, it is still there. The only way I can get the program to see the message again is to forward the message back to the same inbox. But in Peter's code I do not see anywhere where he is keeping track of seen messages between sessions.

Is this something that is done on gmail's end? Refusing to deliver a message to the same client a second time? If so, is there any way I can change my gmail account so that it will always show all messages in the inbox to a client when retrieving the list of messages, even ones already "seen"? I don't see anything in the gmail settings screen.adding a method to send a RSET command to the server, as per this comment on the codeproject page.

VS 2008 : TCP Server/Client "send Hashtable To Client App"?

Jul 15, 2009

i have been working on a chat program Server side and client side i have most of the features i was asked to put in but then once i got most of the bugs out i noticed something the server admin could send whispers and alerts to single users but then when you try do do it on the client side it wont work so i looked through it all and found my issue the user list on the client is only a list of the names in server hash table so i was wondering how do i send the hashtable and all of its data E.G. user connection information to the client so that it can send commands to individual users like the server side can

Public clients As New Hashtable()
' This subroutine checks to see if username already exists in the clients
' Hashtable.  If it does, send a REFUSE message, otherwise confirm with a JOIN.


i tried to send the hashtable over the same method used to send the user names to the client but it cannot convert the hashtable to a string so that wont work so my question is How do i send the hash table to the user from the server then display the username on the client ??

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.....
