Jun 11, 2009I have an application which connects to a database, retrieves a username from a user's table and matches it against the username retrieved with System.Security.Principal.WindowsIdentity.GetCurrent.Name.On my localhost, everything works fine. The database exists on the development server but the application lies on my localhost. All of my authorization and authentication techniques are running smoothly.However, when I publish my application to the development server, I'm faced with the following error.Cannot open database requested in login 'databaseName'.

View 1 RepliesGet Background Workers Use To Make The Connections To The PLC's?
Feb 23, 2010For my project I connect to a large number of variables in multiple Beckhoff PLC's. I connect to the PLC in the Form load event.But the first time connect to all plc's taking too long.The data from the plc's. be sent to my program can not cope with the private sub OnNotification. This is because the program is busy with making connections with various other plc's.If the program is fully launched it works ok, but I also want to start working properly.I solve it just with a timer and a counter. Each program cycle I make a connection, the next cycle the next etc.until all connections are made. This should be better.I would like background workers use to make the connections to the PLC's. bgworkers provide the connection.The main program is not blocked, and the incoming data from the PLC's can be handled properly In the form Load event I start the bgWorkers containing the code for connect and AddHandler. Unfortunately it will not work this way?

VS 2008 .NET Windows Service : How To Make It Work
Jan 30, 2010i have written hundreds of programs with vb.net 2008, but never a service before. I have a simple service written that basically just rights a entry in the eventlog to test. No coding/compiling issues. I run the "installutil.exe" and I get a error ever time. So I went back and added the "Add Installer". But I am sure of what else I need to do, as I get the same error. Please assist.

View 1 RepliesPerformClick() Doesn't Work - How To Make It Work
Feb 2, 2011I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

View 6 RepliesVS 2008 - How To Dynamically Change String To Handle Connections
Apr 8, 2009I have a need for an application with a SQL database back-end. The application will run on a laptop and will therefore be used both on and off the network. I can write the app and I can link it to SQL over the network. I also know how to dynamically change the connection string so I can handle online/offline data source connections. Where the data can be stored on the local client? I'd like the data to be held in the central SQL DB and to automatically copy to the laptop upon connection to the network. The client data source is read-only and will not upload back to SQL. I've seen XML mentioned but that looks overly complex.
View 2 RepliesVS 2008 Async Socket Connections - Clear Out No Longer Useful Sockets From The Server?
Dec 18, 2009I have been developing an async socket connection server and client program. I have been testing it, and noticed that if I connect to the server from my client and then disconnect. Upon reconnecting I am on a different port(local IP still). This is fine, however when I go to send a message, and the server trys to update all the clients, it eventually hits clients that do not exist anymore. I get the SocketException 10054, and upon connecting/disconnecting enough, it no longer works at all. My question is how do I clear out these no longer useful sockets from the server? I am doing currentsocket.Shutdown(SocketShutDown.Both); and then a currentsocket.Close(); after that. When a user disconnects.

How To Make It Work Without The While Loop

MsgBox(aString)
End While
Basically "aString" will keep updating if new data arrives to the server. This way does work, and keeps MsgBoxing every time I get new data, but I don't wanna use While, I need something else, because It won't run any other code, just keeps looping that. :/
