I have created an application using Visual Basic .NET, the application use an access data base which must be shared in server of a local network. The problem is when I run the application in a client machine (connected to the network) I can't connect to the data base.In the same machine the connection work which it's not the case when I change the location of the base to: Data Source="serverIPAdress/DataBase.mdb"
View 2 RepliesI am trying to copy a table from a network database to a local database. I used DAO and could check if the network table existed using a function that tried to assign a TableDef object to the table in question. If there was no error then I assumed that the table existed and the function returned true...Or it would error out and return false.I could then proceed with the copy or not as the case may be.I am converting the code to ADO.net and need to know how to check for a table.

View 1 RepliesI'm building an application which require to use Directory.Exists on a network share UNC path. I know how to use that function, and how to implement it in my code, it's working perfecty locally.
Here my setup:
- VS2003
- .NET 1.1
- It's an Outlook Add-In
Here the code :
Dim realpath as string = "\myserverfolder$subfolder"
Impersonation.ImpersonateUser("admin", "DOMAIN", "adminpass")
Dim isDirExist As Boolean = Directory.Exists(realpath)
If isDirExist = False Then
Directory.CreateDirectory(realpath)
End If
Impersonation.undoImpersonation()
If I build this code, and register it in Outlook with my personnal account (admin), it's working fine, I receive true. If I build this same code, an register it in the Outlook of a normal employee (user only), it's always returning FALSE, no matter if the directory exist or not. The share is set to everyone allow, and I tried giving everyone access to the ACL, and it's the same result.
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 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 ???

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?
My problem is I need to develop a sales application to be used on 5 computers. The database needs to stay on a main computer and other computers should connect with that over LAN.I donot want to use SQL Server as it is too complicated to give permissions, setting up firewalls etc. for the end user.Is that any type of database that could serve my purpose, without giving sharing violation error?
