View 2 RepliesI have developed 2-3 standalone windows application using VS2008(vb.net) + Sql server (2008,2005) and quite comfortable with stand alone windows application. Now i am trying to make a windows app which will share a server database on LAN. I googled alot about this but still no success. So i decided to make that as stand alone app and i just changes the connection string to use remote server database. Everything is working fine still. All the insert, update and delete query are same as stand alone n me not getting any problem while testing through one more remote client system. But while googling i heard abt "CONCURRENCY" control.So please guide me is anything wll b wrong in future wid my this application when i will deploy this to my users? What about locks and how can i implement this to my Insert, update and delete queries to control concurrency and maintain integrity ?Please guide me step by step becoz i m new be to client/server application.

There are problems installing an application developed in VB6 that accesses SQL Server on Windows 7?
View 1 RepliesI've developed a VB.NET application with Visual Studio 2008. The application communicates with SQL Server and processes a text file.
My question is about performance. While I run it from Visual Studio 2008, it takes 3 sec to complete. The same is when I run the executable created by the Setup Wizard on my desktop (Windows XP sp 3). But if I run the executable installed on a Windows 2003 Server, it takes 15 sec to complete! What could be the reason of degrading performance on the server vs. the desktop? The .Net framework 3.5 SP1 is installed both on the desktop and the server.

View 5 RepliesI have a program that reads data from a scanner via the serial port.This program works fine on Windows XP.We have a terminal server set up running Windows Server 2008.I run HyperTerminal on our test terminal, it connects and reads the scanner data fine through COM1.I run my app on that same test terminal and get nothing when I scan.My app connects to COM1 without errors and disconnects without errors.BUT, the DataRecieved event is NEVER getting fired.Neither is the ErrorReceived event.I have played with the Handshaking, with the RecievedBytesThreshhold and pretty much every setup setting I found.Set it up exactly like the settings on Hyperterminal.I have even tried starting a timer on a different thread to call ReadByte every second to try to KICK this thing into doing SOMETHING.Nothing has worked.
I have been trying to fix this for an entire day now.Added events to my class trying to see EVERYTHING that is going on. All I know is, it connects to the port and it disconnects from the port correctly but nothing happens in between.No data when I scan.No event fired at all between connecting to and disconnecting from the port.I have also downloaded other's simple serial communications applications.Nothing in .NET works.[code]
I am having trouble in creating a login form in my windows application.If i create a login form with its database local to the system ,it works fine .But my requirement is that the database is placed on a remote server so that the login is secured.When the user tries to use the application he first needs to login.When he puts the username and password in the login form it should send the data to a remote server for authentication.

View 5 RepliesIam developing a Windows application using Visual Basic 2008 with a SQL Server database. Throughout the program I give the user as many options as possible and have no problem with either the database or the windows forms. The program does not initially require a Login and I want toprovide the User with the opportunity to add a Login to the system. The default Login form is perfectly satisfactory.
The problem is that I can't figure out how to program the change sothat the Login from isopens the program rather then th form designated as the StartUp form. this forum I am able to prgrammatically change the form but I can't figure out how to make the requirement a permanent factor. I tried using a Constant, but if the User wants to change, you can't change the constant. Its an apparantly simple yes/no situation but if I set a varable to yes and then change it to no the next time the program runs, the change will be lost.
Web service uses SQL Server based authentication how to change to windows based authentication both web server & Database service resides in different domain .
View 1 RepliesWe are currently using Access 97 as our database. This resides on the remote farm server (which is a Windows 2008 R2 server). We are using a front end vb6 exe which accesses the back end data.Occasionally we are getting corruption to our database and we have to make sure everyone exits the software to allow us to repair/compact it. There are 2 physical servers, each running 2 virtual machines. When the user logs onto the farm using RDP, they go to one of these 4 virtual machines.We are getting all kinds of corruption, some where # characters have been inserted into the top of one table, some where the indexes are corrupted, and some where access needs to repair the database.
View 1 RepliesI am working on moving applications from Windows 2000 to new server Windows 2003 R2(64 Bit). I noticed that there are some VB programs and config files for those programs have been placed in Windows 2000 Registry. Some other applications are using them from different servers.Why do we use registry here? How can i move these to registry in windows 2003? Can I just move these or do I have to write VB programs to place them in 2003 registry?

View 4 RepliesI have a problem with scroll in a treeview in a Windows forms application (Framework version 3.5).
The strange thing about the problem is that on Windows XP, Windows 7 and Windows 2008 the scroll works as excepted, but in Windows Server 2003 SP2 the scrolling doesn't work. Enable/disable Visual Styles doesn't seem to make a difference on Server 2003.
Steps to reproduce the error:
1. Add a treeview to a form and add x nr of root items (and 1 sub item to each item).
2. Expand a number of nodes. The non-standard thing here is that we are changing the node integral height because we display a usercontrol with the treenode (See example of the code below).
3. When you scroll afterwards, you cannot scroll to the bottom node. The scrollbar is all the way down, but we are not seeing the last node.

View 1 RepliesWe recently upgraded our job server to Windows Server 2008. We have jobs we run manually in a folder (c:Custom Programs). Some programs are console programs others are have a gui. This one program has a gui.It also has a progress bar that shows the progress of the job when you click the go button. Of course it spawns a thread to do the processing. This thread creates a log file to write errors and other things too.
The problem is when the program goes to create the log file an access not authorized error is thrown. I checked the permission on the folder. All users are allowed to create/edit/append/execute. Pretty much everything except take ownership. Also, there's nothing that denies anything. So I see no reason why this isn't working. We can get this to work by using the run as administrator option when we first run the program. However, we don't view this as unacceptable solution. My only thought is the spawned thread isn't getting the same permission set as the program. Am I correct or does something think it's something else.

I have an application I have developed which works great on individual PC's. However I've had some interest from a few customers that asked if I have a network version for site licencing.If my app did not save any data or write any reg entries, this might have been ok. But it does to the local computer. I also built in my own copy protection and trial function that stores data in the registry on the local computer.What would I need to do to enable my application to run on a server/network share, so that the only a serial number needed is for the server?
