Windows Application + Accessing From Outside The Local Network?
Jul 12, 2011
I have developed a windows application for my company. It is a multi user software and we are using sql 2008 as the database. The sql 2008 is installed in our company server. Within our LAN, there is no problem in accessing the software and its working pretty fine.
Now the problem is, some of the managers need to go out frequently(for business tour and all) and they need access to this software. The software is already installed in their laptops.Is there any way to access the database that is in our company server ???
We have few static IPs with us, is there any way i can use that here (Using NAT in the firewall or something)?

Basically back in VB6 days, I created several VB6 apps with Access as the backend database. I'd package my Access db file with the application setup, which copied it on to a shared network drive, and then different computers on the LAN could use the same backend database file, and that worked just fine. With SQL and VB .Net, I've done work with a SQL database hosted on a remote server, so you can basically build your query string easily and anyone can connect to it from anywhere, and it works just fine.However, what I'd like to do is have a local SQL express database as the backend for a VB .Net application and make a setup program that can install it in a way that it could be shared on a Local area network, without the user who is installing the application do anything.
I know about building a connection string with the local machine name, but I don't really have any experience with including an actual MDF file with the application. Does anyone know how it works, and is it a better approach? Does it work similar to placing an access file in a shared unc path?I know that ClickOnce (which is awesome) can install SQL express easily on a user's machine. However, the key is that I want SQL express to be installed only on the machine that is going to be the database server in a LAN enviornment, and not on every machine, unless it is neccesseary. And then how does your VB app know how to build the connection string to access the database from any machine on the local share?

Our company runs Windows Server 2008 R2 and as part of the normal login procedure you type your username and password. IT sets the domain when you get your PC so that is all good. So, when you open IE, the intranet sight detects that you are person XXX YYY and then logs you into the site automatically as the right person.
Now is there any way that I can do the same with an application written in C# or VB.NET. I.e., I would like the user to not have to log in as they have already done so during Windows log in, and then use the application as the individual user. This is for loggin purposes and specific rights for each group.

The application sits on a virtual environment and when I remote in and run the application, it connects to the remote database. However, when I remote in with a service account and double click the same .exe, it tries to connect to the local host database and ignores the app.config. The code is the same, only the login name I use is different. The login I use is part of the local admin group. Any ideas?

i'm using
Public con As New SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Tramsco\Tramsco\payroll.mdf;Integrated Security=True;User Instance=True;MultipleActiveResultSets=True")
as my connection string and when i run the .exe from the other computer to access the database on the host, it gives me this error:
An attempt to attach an auto-named database for file C:\Tramsco\Tramsco payroll.mdf failed. A database with the same name exists, or specified file cannot be Opened, or it is located on UNC share.
but when i use the computer where the program is, i can run it with no problem.

im making an application and i need to install a printer in a computer. The application im trying to do is a client-server application so the idea is that the server send the instruction to the client telling him what to do and then the client will do it, in this case it will go to a SAMBA directory and it will get the drivers for the printer model from there and after that it will install the printer, everything in silent mode.

I have a .NET 2.0 *.dll that calls My.Computer.Network.Ping(). The *.dll is then run out of an *.exe via AppDomain.CreateDomain() and Invoke(). The problem is that this works just fine under Windows XP but under Windows 7, I get an exception saying that no network connection is available. I tried the Ping() call out of a small console application under Windows 7 and it works just fine.

I am developing an application, which hunts the local network for attached computers then checks for a share and a file, if found it displays it in a listbox. While testing this I have seen some strange Chinese or Japanese computer names pop up and in a few seconds go away, the names seem to always be different.

FormA calls DialogB where user cancels DialogB which exits via ForceTermination(), see insert.Caller FormA check for DialogResult not = OK, which it isn't, and I can see this in debug as Abort(3).However, the code continues merrily along its way until I get a 'null reference' error which I'm trying to avoid via Force Termination().This is caused by the user cancelling DialogB, a selection process to get a database (SQL) instance.[code]
