I have developed some software(vb.net) that records fees paid by the students. The purpose is that the database should be stored in a server, which can be accessed from any stations linked with it.This is working fine with a network of 10 computers. I need to publish it over the net so people could do this job logging in over internet. Database (access database) should be stored on a web based server.

I already know how to call insert, update, delete & select procedures in DataSet.xsd window. And I also know how to call queries by table adapters. But I just found out that its not possible to call all functions by queries (such as insert). It works when I test the query but when I try to add it, it says "Failed to get schema for this query". So I built a few stored procedures which do many functions (such as transaction, insert, update etc...). But I am unable to use these stored procedures in VB form. I found some tutorials mentioning that it can be done by defining connections and some other stuffs with which I don't want this to be. I want to call these procedures by writing code in VB code editor window with DataSets, TableAdapters, BindingSource etc...
View 2 RepliesI am developing an application that runs on a network. It needs to contact to database (access database) very very often, which is stored in server. Around 30 Client computers contact the database almost every 2-3 seconds. I need to know could there be potential manifest problem in with the application? Could there will be a problem if database is being updated by one client, at the same time other client contacts it?
View 3 RepliesI have got a MySQL database stored on a remote server. I can user PHPMyAdmin to access the database and make changes to the table, i can also use a third party piece of software to do the same however when i try and access the database through my program it says that "Access denied for user 'lukefrost'@'%' to database 'PHCAdminSystem'". However it will allow me with the same logon credentials the other ways explained above. Can anyone help me with what the problem might be?

View 11 RepliesI've been working on an application for awhile that, basically, allows the viewing and printing of a maintenance database. It allows the user to view basic information for the object and then view the maintenance history. My approach for the maintenance history is simply to have unique tables per object since a history has to be kept for each, however, I'm running into a problem in the application that allows the user to view the general information from one DB and the Maintenance history from the other DB.
Say you have Object ID BG1. I can enter the object ID into a search field, pull the data from the general DB and display the data, but I also need it to pull the information from the maintenance history and display. If maintenance history for this object is not found, then create a new table within the DB, fill the columns with the required fields and allow for the user to edit the history.

View 8 RepliesI'm making a VB.NET application with an SQL Server 2005 in the background. Naturally the user can not edit the database directly but will use a number of UI features to be able to add and modify the data.However, there are a few tables that should be easily accessible from the admin interface such as specific information about a vendor. What's the easiest way to let the user edit this data freely? One way would be to use a DataGridView but this could appear complicated to the user, plus I'm not sure exactly when to save the edited data back to the database.
The best way that I can think of is to create custom dialog boxes for adding, deleting and changing the information, but this seems like too much work for such a small feature.

I just started learning VB 2010 through a book. I'm learning vb to design a program which can manage customers of a small company as a homework. It'll store data (Company Name, Phone N. and Adress) at an Access Database. (I'm using Access 2007)
I have a little background with programming but none with databases. According to the book there is no way I can delete, add or update a data from an Access Database without installing SQL Server or Express. But this program should work at a computer which may or may not have SQL server or MS Access (Any computer with Windows OS).
After a little digging only thing I could find was Walkthrough: Saving Data to a Database (Multiple Tables) from MSDN and did every step and at the end, I can delete or add rows and change values of the cells but cannot save them (when I click save, close the program and re-open it, changes are gone).
I don't get that how can I view all the data from database without SQL server but can't save changes to the database file without SQL Server.
Is there a way to do this without SQL Server? If so, can you give the right code for the MSDN Walkthrough's Save button? Or point me to a page where can i learn the right code?
Recently working in vb 2010 express. I'm using service-based database which is based on SQL Server. This database will be deployed at the server.

Does the service-based database support multiple connections?

I have developed a Windows Forms application using VB.NET and MS SQL Server 2005 Express Edition. My database name is 'AC'. I do not want ANY user, SQL Server or Windows authenticated, to access, read, write to, update, drop or take backups of this database, except this login 'Adel'. So my connection string looks very similar to:[code]What configurations should I make in the MS SQL Server Management Studio 2005 Express Edition to 'Adel' login, 'AC' database, and all other logins to accomplish this?Given the following:I do not own the server; my client owns the server. They have a domain set up (LAN network).They have ASP.NET applications running using other databases on the same server. However, these applications have nothing to do with my database 'AC' or login 'Adel'.Some of their applications do not specify 'User Id' in the connection string; they use 'Integrated Security=True'.

I would like to create a server program that accesses an "ms access" database. I will also need a client program that connects to the server. The reason for this is that the server is a mediator for several clients. Since I am using access, I plan on maybe having 20 or 30 clients connect to the server only. The client will have access to a virtual market. So when a person buys or sells something on the market, the server mediates the transaction and etc. At the same time, the access database saves each clients data as well as the overall market data.
