Remote Connection To A Sql2005 Database Through Hamachi/VPN?
Oct 20, 2010
I would like to test a remote connection to a local Sql 2005 Database first thru Hamachi using a small exe that would be set on the client machine to let me know if the connection was successful or not, in the close future the connection would change to be set thru a VPN but for now i would like to accomplish this by using Hamachi software.i want to code the client .NET exe file to connect to the server, Hamachi gives an IP address and hostname once installed on the "server" machine so i wonder how should i include both in the connection string of the client exe file.
I'm trying to make a rather simple Visual Basic app with which I can update some tables within my MySQL databases.I've been following this tutorial from page 3 on, as the first 2 pages where on how to initialize a local MySQL database.My MySQL database is on my website, so I thought I had to use the website's name instead of "localhost". Anyways, I now use this code:
Dim connection As MySqlConnection connection = New MySqlConnection() connection.ConnectionString = "Server=resload.com; Uid=***; Pwd=***; Database=***;"
[code]....
But it popups (don't now whether that's a real word :p) with the message:Error Connecting to Database: Access denied for user '***'@'my ipaddress' (using password: YES)?
I am building a database application using MYSQL as the backend. The MYSQL instance will be installed remotely on a share host. I have access to SSL certificates. I'm obviously not looking for any code but, conceptually, how do I go about securing the connection using SSL between my application and the remote MYSQL database?
I have an MS Access 2003 database built that resides on a shared network path at the company I work for.The database works perfectly for users connected directly to the company network.However, when a user tries to open the database while connected remotely to the company network (they can still access the shared path), they receive the following error:The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.At the time that they tried it, they were the only person accessing the database.They tried a local copy as well as a copy on the network shared drive.[code]
I am new in programming and I am using VB2005 and I can user either SQL2005 or MS access database.Here my scenario:I have created a project where the user can add a new record, (Support Desk) there are times when a new record is added, it may need a backup (Pictures, Document)to be included in regards the problem.

I am using VB 2008 Express and have created an application that connects to a SQL database to populate a datagrid.The application is working properly on my computer but will not on others 'remote connection permissions' error.After some googleing I found that the express version is crippled to only work on local machines that use a database.If I purchase Visual Studio 2008 Standard Edition, import and rebuild my application, will my application be able to run properly on other PC's?
Rather than use an Entry name of an existing VPN connection, is it possible to connect to a remote network by creating a temporary connection on the fly by using the remote IP/Host name, username and password?

I wrote a program in Visual Basic 2008 on my laptop that runs windows vista 64 bit, well the program attempts to access an Sql server that I am running on my laptop and it continues to give me the following error:
Is there anyway, in a program, to detect if a program is being run from inside a remote desktop session or if the program is being run normal in .NET 2.0? What I'm trying to do is, I create a timeclock application which will clock a person in and out and keep track. But this particular person, I suspect, is remoting into their computer at work, from home, and clocking in and out.
I have configured Sql Server Express on a server, Enabling TCP/IP and Named Pipes to accept remote connections. However when i attempt to connect from VB.net on another PC on the same network I get the following Error: Failed to login user "ServerNameUser".
Can anyone offer some server setting and a ADO.NET Connection string. The attached file has the Sql Server Settings.Attached Files sqlRemoteConfig_Current.txt (806 Bytes, 70 views)
I looking for a solution for how to check if a connection to a remote computer exist or not using vb.net.
I 'm writing a program which will request data from a remote sql server. I need to check if the connection to the remote server exist, before open the connection or run the the sql command.
I Downloaded MySQL Connector (the latest, 6.1.X), and i cant really understand how to use it in VB.Net... I Added it to references. All what I need to know is what imports to use, how to set connection with remote server and how do I select and insert to tables.
I built a window's app in VB. The app is made to be used worldwide. The app works fine when it is installed on a computer using the same network than the local machine hosting the sql database. The problem actually, is that, when the app is installed on a computer using a diferent network, the connection fails.
I've came across a little problem with my tcp / ip server. My client can connect to it with 127.0.0.1 ( localhost ), and 192.168.0.X, but every remote connection fails to connect.
Here's the connection rituals: Server listener = New System.Net.Sockets.TcpListener(System.Net.IPAddress.Any, Port) listener.Start() listenThread = New System.Threading.Thread(AddressOf doListen) listenThread.IsBackground = True listenThread.Start()
I'm having an issue here with making a WMI connection to a remote machine using specified administrator credentials.I have the WMI code inside a function, I pass it the computer's name and it returns the WMI information that I am requesting as a string (or in this particular case, an integer) from the remote machine. I'm positive it works, and returns the information I need using specified admin username/password. NOW, the issue I am having is related to (it seems) calling this function from a backgroundworker. [code] "Value does not fall within the expected range." I literally have no clue why this would throw that exception, yet when I call this function from lets say just a random button on my form, it works beautifully. The key here is that I need my WMI requests/processing to run in the background.
I have a fat VB.NET Winform client that is using the an old asmx style web service. Very often, when I perform query that takes a while or pass a large amt of data to a web service in a dataset, I get the subject error.The error seems to occur in < 1 min, which is far less than the web service timeout value that I have set or the timeout value on the ADO Command object that is performing the query within the web server.It seems to occur whenever I am performing a large query that expects to return a lot of rows or when I am sending up a large amount of data to the web service. For example, it just occurred when I was passing a large dataset to the web server:System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the rem
I'm looking to write a custom program in VB.NET / C++ / C# that would allow me to monitor a system's vitals over a Remote Desktop Connection. I'm only looking for tips on how to implement a connection like this in code (eg. is it just a simple object or call to a WScript function? or is it much more sophisticated?). As to the specifics of operation after making the connection, I have that figured out based on another program which shares some similar features. This doesn't have to go through an RDP connection, I'm definitely looking for better ways. Reason I mention RDP is because I currently do this manually over an RDP connection, but I don't wanna have to constantly open the window.
i created some buttons to start a remote connection with some server.Private Sub Button15_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button15.Click Dim RetVal
RetVal = Shell("mstsc.exe /v 10.100.6.11")End Sub But now the remote connection starts minimized, how can i fix this so it starts maximized,i dont want to use /span because some people use 2 monitors and don't want it "widescreen"
I have an application that copies a file from a network/internet location. I am trying to catch the exception for when the network connection becomes unavailable (or internet goes down). Currently i catch the exception "Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host." which occurs on the bold, underline line below.The issue i have is i try and attempt the operation to continue doing what it was doing by resetting variables and then reassigning them to continue reading the stream but cant get past this error. The only way to go past it is to stop and start the application which is not what im after. [code]
I am Using Visual Basic 2010. I want to check My Connection Status. Connected or not in Remote Server Connection (SQL Server 2008 R2). How To Check Connection Status..?
I was developing a website on development server. I created a user authentication and access rules on my website. So VS created Aspnetdb. I also created a login page using in built login control. I deny all the anonymous users to the page so it will redirect to login page everytime.
Now that I moved aspnetdb and my website to the remote server to the new hosting I bought. I also merged few tables into aspnetdb. But I don't know how to change the connection string for that login control. I didn't write any code myself for that and there is no connection string in the web.config to connect to aspnetdb. For other pages where I created from scratch myself, I changed the connection strings to the aspnetdb and it works fine, but Login control don't.
