Integrated Database In The Web Application?
May 5, 2011
I integrated my database in my web application. Previously I was just referring it to SQL server 2008 by defining a connection. Everything worked fine data was being fetched, calculations are done. Now when i integrated my database in the web application, problems arose.
Dim cost3 As Double
cost3 = Dataset.Tables(0).Rows.Item(0)(0).ToString
The problem is with this the error says: Cannot Convert type String "" to double. Before no such problem showed.

I have some certain files that my program references.I know some programs have a folder in the same place as the .exe, sometimes called "Dependencies", and in that folder there are files that the program uses.For example, take the iTunes folder.The iTunes folder in Program Files contains the iTunes.exe, some DLLs, and some folders that contain files that the program uses.How can I setup my program so that it does this? Everytime I add a file in my program it gets integrated into the .exe itself which in turn creates a huge file that lags. I want to have the .exe, and a folder which contains files that the program references.

I buit a ASP page that gets the users information who is logged into the computer ie username etc. This was using IIS6 Now I've moved over to IIS7 on Server 08, I set it up to use "Widows Authentication", however when i run my ASP.NET Page it uses the account NT AUTHORITYNETWORK SERVICE to do its work.Ive looked all over online, and cant find a way to fix this.I just want to pass the user credetials from logging into the computer, to the web.I've made sure that I have this in my web.config
<authentication mode="Windows"/>
<identity impersonate="true"/>
When I run this the site from Visual Web Developer and it creates the site, it pulls back the correct information.However, when I Then to my browser and check this and it dosent pull back the correct account, it pulls back that NT account.etc. but it always seems to pass the same wrong account NT AUTHORITYNETWORK SERVICE it should be my accountname I am logged in with.

I am creating reports in Crystal Reports that is integrated within Visual Studio 2008, and I noticed that some of the features are disabled. One is the ability to link tables with a Right Outer Join or Full Outer Join. I also cannot "Show SQL Query" in Crystal Reports. Is this something I can enable or do I have to purchase or upgrade?

I have started using the builder class to create my connection strings for the sole purpose of making more generic connectivity code. However, I am stumped on this issue. The MS eConnect product apparently expects to receive integrated security=SSPI in its connection string if you want to use integrated security, (vs Integrated Secturity=True). I thought I would just pass "Trusted_Connection"="SSPI" to the builder class.
as it turns out, the item for Integrated Security is boolean and despite what the documentation says, will not give me SSPI in my connection string. Has anybody else found this issue and is there a simple fix for it? as for now, I'll simply strip out the item and replace it in my string.

With VB.net, I'm coding a simple application to get more used to the new .Net format.
I'd like to save all the information to a 'new' database file. how to create a database on the fly, once that is done i'll be able to connect to it no problem, but actually creating the file is proving difficult to work/find out.
Also, with vb.net and the newly created custom file, how can it be made to automatically open that information with the program?
Is there a method in installation to associate the file type with the new program? How can i check when the program loads if a database file has been 'double-clicked' (rather than just running from the .exe of the program) and proceed to load the data?
EDIT1 - Extra InfoThe windows application has many different fields and content etc, then i need to save that to a file that could later be loaded by 'double clicking'. I assumed the easiest way would be to create a mini-database for each unique file

I need to code a program that makes use of a database. It's gotta be for a local business, so I chose a pub lol. The database has the following columns: Beverage; Cost; Total number of sales; Income.
What the application needs to do is basically work as a cash register. Each beverage gets its own button, each click on the particular button displays the total due that the customer has to pay.
That, and the same button has to edit the database fields and update them or add to the values.

so this is more of a question about application security.Say I have a application that authenticates to a database. The Users table has the following fields: UserID, UserName, Password,Salt, Active, Permissions.
The permissions field will be related to another table called "Permissions" that has a unique ID and it describs the level of access the user has to the system (reporting, add/remove users, etc).Now the question is, when the user autheticates and executes an action on the application that requires a certain level of permissions, is it better to have a class the holds an authenticated user or is it better to have the application query the database for the users permission level?

My application has an access2007 db as its database. I am trying to create a backup/restore utility in my application that allows the user to take the backup or restore the database file "StudentsData.accdb" which is in the application folder. I tried the filecopy method but it gives me an error saying that the "file is not accessible, as it is being used by a process." I believe it is my application process that is using the file.
How do I stop my application accessing the database? I have database connections which i have written in code and all of them close with their respective forms.
