Recently i had a discussion with someone about the proper way to develop a database driven (SQL Server) application.In his opinion i should design also the database inside the application.At this moment i design the database in SQL Managaement tool and use a custom class to connect to this database (or the one of the client) in my application.What are the cons and pro's of using the VS database designer inside my IDE?

I recently developed three very independent applications of each other and showcased them to a professional. He praised the inventiveness of the softwares but gave one suggestion that "We would like to see a suite of these applications." I developed these applications as a hobbyist but now want to move forward with the suggestion.
View 5 RepliesI wish to develop windows mobile applications, preferably using VB (I 've done this in the past with VB6). What do I need to install? All my searches result in information about using 2005/2008 versions of Visual Studio, which seems odd if Microsoft are pushing to use Visual Studio 2010. I would like to use VS 2010. So, can I develop Windows mobile applications using VB 2010? If not, what version of VS do I need and what language should I use?
don't complicate the issue with a load of flannel. I just want to know that I need to install - this, with this SDK, these utilities and write your software in this language (ideally VB).

View 6 RepliesI'm a first time visitor and poster, but I'm definitly going to stick around. I'm running an old version of Visual Studio .Net Academic 2002 and the .Net framework 2.0. I'm stuck on an issue regarding the deployment of a few programs I've thrown together. They all work fine on my development machine, but the problem they all use SQL Server databases, and I can't find any specific help on deploying a windows application with a database on a machine that isn't set up basically just like my development machine.
I know that I need the .net runtime bootstrapper on the target machine, so I can run basic programs that dont use SQL databases. That's no problem. But what about programs that make heavy use of databases? How does one go about deploying it on target machines? Is there a SQL server bootstrapper?

I am developing desktop search engine. For that i am maintaining indexed database with file name and their path. The indexed database is created at once by scanning all hard disk. This indexed database is further updated when user creates, deletes or renames file. The updation task is carried out by an windows service application and for searching files on hard disk I have created another windows aplication. The problem is that when windows service is updating database, windows application can not read database. It gives error 'Cannot open user default database. Login failed.Login failed for user 'WINXPSwapni'.
View 1 RepliesI have an application which takes input on a local machine and sends it to a database stored on a server. I'd like to be able to deploy my application over a number of computers (all on the same network), all of them updating the same database (on the network server).First of all, will this be possible without putting together a completely new application to handle all connections to the database and sorting the entries?
View 7 RepliesWhen I try adding a new data source to my project I get a prompt saying "The connection you selected uses a local data file that is not part of the current project. Would you like to copy the file to your project and modify the connection?"This sounds rather obscure to me, as I'm new to VB.NET and programming non-script apps in general. The data source in this case is a .sdf SQL CE file.
Question 1: If I say that I want to copy the database to the project, what will happen after I compile the app, where the database will be? (how will I edit it from another app?)
Question 2: If I do not include it, how the data source will still keep linked? Can I link using filesystem enviroiment variables like %ProgramFiles%MyAppDir?
Question 3: Can I just tell it to use a read-only (Just needs to read it) data source on the web, like on an FTP?
Do users of windows applications have to have the database application installed if your program uses databases to store information? For example, when making VB2008 programs, if I use the visual studio express database (.sdf), or maybe a MSAccess database, to store information within my visual basic program...when I deploy the application to the users, can they run the program okay even if they don't have MSAccess installed on their computer?Also, do I need to have MSAccess installed in order to write programs that use MSAccess databases?

WinFormsApp then uses Decryption key on Hardcoded encrypted connection string and renders application usable.This would then eliminate the necessity to encrypt/decrypt a connection string at runtime, virtually rendering any unauthorized person with a useless software.

View 11 RepliesWhenever I work with applications involving database I have this habit of declaring a global variable that holds reference to a Connection object and keeps it open throughout the lifetime of the application and closes and disposes it accordingly at program exit.I've been doing this since my VB6 days and still doing it now in dotNET. I've read a lot of articles regarding this practice and most of them states that it has great impact on connection pooling. Does this also mean something when my application connects to a database file (i.e. MS Access, flat text files)? Is it true that the DataAdapter and Command objects open and close the connection?

The problem I am experiencing has to do with using DataGridView.Member to access a BindingList.
My app has a UserControl called MaterialsControl, on it lives a DataGridView name dgvLineItems. Using the designer, I've set the DataSource for dgvLineItems to the MaterialsControl. MaterialsControl also has a "Items" Property. "Items" is a BindingList(Of LineItem). dgvLineItems.Member is set to "Items." The LineItem class implements INotifyPropertyChanged
Presently, when I add anything to Items, the DataGridView does not show any changes.Alternatively, when dgvLineItems.DataSource is set to Items (which to my knowledge can only be done manually), anything added to Items appears in the dgvLineItems.
Just for clarification, the DataGridView I'm using is for output primarily, the user will be able to delete values from the view, but not edit them. Insertion is done through an event handler.
I'm working on some code that was developed by the previous developer of an application and I don't understand why he used a certain syntax for IndexOf().This is the code (MyString is just an example of the string being searched for): [code] I can't seem to find any documentation for this unless it's inside of a loop where the number after the comma is incremented.

View 2 RepliesI'm using VB.Net 2008 .NET 3.0.I am not sure of the proper,or best, way to use Settings and Resources. For now I use the default project wide My.Settings and My.Resources.I have a class that I would like to reuse in other projects, so adding project wide settings or resources in each project doesn't sound proper, nor does creating constants and variables within the class itself.
I'm guessing there is a way to give a class its own resource file, and maybe even settings file, but I'm not sure how to do it. I tried adding a resource file with the same name (but with .resx extension) and I got a weird error saying I was trying to edit a resource that is apart of another project. I continued, but it didn't seem to be what I wanted and I wasn't sure how to access that new resource.I'm not currently concerned with internationalization, but it wouldn't hurt to understand how that would affect what I'm trying to do.
