I am very confused about the database type to be used in my vb.net application. I have been using SSCE database, but for that user has to download and install SSCE, which many of my users do not want. If I use Access, the security issue is very very serious.

If I use Access, the security issue is very very serious.I have downloaded a few database apps from the internet, which donot require any such thing to be installed and also I see no known database format in the application folder. I wonder what kind of techniques they are using.

View 2 RepliesI have to develop an application using MS Visual Studio 2005 or above with the following objective:
* The application should allow users to create as many new forms as they want and each form should behave like a MS Visual Studio WinForm. By saying that it should be a container for drag and drop of controls from the toolbox that I will develop....
* Once the user design's each screen to his taste by placing various controls on the form, he should be able to save the form as a screen. Of course I have to provide functionality for each of the controls such as if he drags a button on to the form, he should be able to specify what action it has to perfom when clicked when the application is put into run mode. Quite similar to regular windows form button.
* My application should have two modes: a DESIGN MODE, where user can drag, drop controls and specify what they should do when put into RUN MODE. This is quite similar to MS Visual Studio designer.
* Last but not least is to be able to access the application via the browser with the same look and feel his desktop version.

View 2 RepliesI am trying to make a web application in VB.NET using Visual Studio 2008 that will accept login credentials and compare them with an Access database for authentication/validation. I found lots and lots of examples for how to do this with a Windows Form App, but none with a ASP.NET Web App. tried to modify the steps for a web app but I'm not sure how to make it work. The database connection is good and the query seems to work fine. Here's where I'm having trouble. In the tutorial, he says to use:
01 Private Sub But_Validate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles But_Validate.Click
02 Private Sub But_Validate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles But_Validate.Click
03 Dim r = Me.UsersTableAdapter1.ValidateUserNamePassword(Me.Txt_UserName.Text,Me.Txt_Password.Text)
[code]....
No matter what I put in for the username and password (as long as they are valid values) I always get a "success," never a failure. I know my query is working right because I put a gridview on the page and bound it to the result from the query; when I type in a user/pass that is not in the database the gridview is blank, when I type in a correct user/pass the gridview displays that row from the database.
I have put at least 4 hours in to figuring out why i cannot view my results when I run a datagrid in my 2010 visual studio WPF application.Also, it looks like it is only filling one record in the datagrid.

i am working on a project and i want your help for something. I use access database and visual studio vb.Net. In one of my forms i want to get records in a datagridview , between two dates . For example , i have the table Sales and i want to see all my sales between the two dates.
[Code]...
In my project i have different users lets say 100 users. My problem is most probably authentication. What i wanted to achieve is this;1. When user1 creates an account (saved database) with the following details
name: user1
lastname: user1
When he/she logging in into the system that information must be viewed by him ONLY. (authentication)
2. If user2 logging in he/she can't view the information of user1 (obviously).
