Programming Login - Developing A Windows Application Using Visual Basic 2008 With A SQL Server Database
Feb 26, 2011Iam 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.
VS 2010 Database ADO Programming Required?
Jun 24, 2010I am writing a program which includes access to a Microsoft Accsess database. It is running fine on my work computer (windows xp) but when I transfer it to my laptop (windows 7) to work from home it stops running on the "open" statement. I have stripped out all other code so that I just have a program with this in:

Again this will run fine on my desk computer but will not get past the open statement on my laptop.Interestingly, if I start a brand new project on my laptop and paste this code into it - it runs correctly.

VB 2010-Access Database Without SQL Server
Nov 5, 2010I 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?

View 1 RepliesSyncing Database Client Server In VB 2010?
Mar 24, 2012I'm creating a VB2010 application which will require a connection to MSSQL. Should I Install SQL 2008 on my computer then use MS SQL 2008 as my data source or skip installing SQL 2008 and use MDF instead?
Also the program must have the following requirement
Program must use SQL as their database source End user must not install SQL server on their machine Program must be able to update (sync) the local SQL database from SQL server on the web. (User will have option to delete everything on their local database and load everything fresh from the server or to merge the update with existing data) Programs will (most of the time) run in an offline environment. When the user have access to internet they can update the database The program must allow user to add,edit, delete their local database while offline Only certain user (authorized user) can update their local database back to the serverC
Is it possible to created a program that meets all the above requirement ?

View 1 RepliesSimple Client-server Application Programming?
Nov 18, 2010I'm trying to learn how to do some very simple client-server application programming.
Basically, I want to make a program (the server) that listens and waits, and when a commend is sent it will run a batch file or execute a line of code.
The client will just ask for the ip and send the command when a button is pushed.
Shouldn't be too hard right? So what are some good resources that you've used to get started?

Can't Connect To A SQL Server 2008 Database Using VB 2010 Code
Sep 24, 2011First off, my apologies for being a complete Newb! I have a SQL Express database that I use quite successfully to track my investments in several accounts. I built it myself, it's quite functional, and Im happy with it. The problem is that there are multiple account tables and updating them can be tedious in SQL Server, if multiple purchases and sales in multiple accounts have occurred in a month. Tedium can lead to errors¦

VS 2010 - Database Connectivity With MySQL Server 2005
Dec 3, 2011I am using Visual Studio 2010. I want to do database connectivity using VB.Net and MS SQL Server 2005. I know 1 way of doing this. Following are the steps...
1. Create a new Data Source Using Data Sources Window.
2. Select the appropriate view like details view/ data grid view for that data source
3. Drag that data source on your form and connectivity is done. Also all the controls are created by the visual studio.
This feature is really cool but I want to learn database connectivity by pure coding without using such advanced features. Also is it possible to do connectivity from a class library ?

Server was not found or not accessible please verify the instance name is correct or allow remote connections.I have read numerous forums on this saying about changing the connection string and instance name.but with being novice i dont understand what needs to be changed etc.The sql server allows remote connections, but i am unsure what else needs changing to allow the application to work with the database on another machine.

May 10, 2010The above is more or less the complete question. I have created a table in the VB 2010 Database Explorer but I cannot for the life of me work out how I can get this copied or created into the underlying server. It is not appearing in the underyling serverand when I run the code of course I ge "invalid object <tablename>" I have data as well in the table that appears in Database Explorer. I think I have missed something fundamental in my overall conception of using VB 2010 Express with SQL Server Express in that I don't know if I have a local copy (that isn't then mirrored on the server), or what (the ____ have I got)? An article that explains the overall relation of Database Explorer to the underyling Server would be great as well

Get Templated Starter Database Driven Forms Generated In C# Winforms SQL Server Using Some RAD Tool Or Visual Studio 2010
Aug 11, 2011I hope I got all that in this question title. Let me explain. We are starting on small desktop app that will snowball into a big app with many forms. The database is SQL Server. It will have classic stored procs/functions performing classic CRUD functions. Given a table or stored proc in SQL Server what is the quickest way to create a form with all the hooks to maintain a table.
For e.g. lets assume I have table like this (most code below is pseudo code)
Table Employee
{
Name varchar(30)
DOB Datetime
Address varchar(100)
}
From this as source I want to create my Target which is form with 3 labels and 3 textboxes with add delete modify buttons (or OK button to add if not exists or modify if exists)
[Code]..
The code generation tool or technique that will be used should generate the correct db hooks (create SQL parameters, SqlCommand, execute sql.. basic try catch etc. Is there any open source tool to do this ? Some trick or templated approach via VS 2010 ? Worst case any third party tool ?

IDE - Calendar Programming And Database Linking - VB 2008 / Access 2003
Jul 21, 2009The Calendar control (the Month Calendar) control in VB 2008. I am creating an attendance timesheet and I want the Calendar to color each date differently like e.g An employee Paul is selected from a list.
On the calendar I select the month. (The dates are not supposed to be selectable). Then lets say it is June. He is late on the 1st and the Second, so those days are supposed to be colored red (the whole block). Let's also say he is absent on the fourth and so I want that date to be coloured black. How do I do this? I tried finding a query and my friend told me that this functionality is not available in the current control and that I was best off making my own control (???).
I have tried selecting specific dates and bolding them (there is a function that allows this) but I am stumped trying to find two different ways to differentiate colours. Second:- How do I link a calendar with an Access Database?
