I have a connection string in my database which I read throughout my VB .Net application. I have another string which is NOT a connection string though. It instead has information about a domain on LDAP. So LDAP string just needs to be stored in the web.config as a string, and also to be retrieved as a string.

View 1 RepliesI built a small website and there will be only one admin, so in the admin panel I am asking for a password with a value that I do not retrieve from a database, I just hard coded it in the function in code behind, I know this is wrong though I don't know why.
So is hard coding it in web.config the right thing to do? and how?

View 2 RepliesIn my application I have many different forms each use 3 different database. And right now I am placing the connection string in each form but when it is need to change I have to change in every form. Now what I want to store all connection string in a vb class and call them in every form. So that if I need to change I can do in that class. I have stored my connection string in database so even I don't want to connect to database again and again. I have some idea in which maybe a public class is used and some how I will call it on other forms.
View 2 RepliesI need to store/retrieve a bit from a data table of 3.268.760 bits long.
Using w As New BinaryWriter(File.Open("test.bin", FileMode.Create))
for x = 1 to 3268760
For i = 1 To 3268760[code]....
the w.write(?) stores a boolean value meaning 0/1 for false/true values, but Vb.net seems to use an whole byte to store this data which is too expensive for my table (3.268.760^2).Is there a pratical way to store/retrive single bits from a file using vb.net? (meaning as little as possible conversion to other types).
I'm trying to build something called a structure which will store data it retrieves from a text file. I have the structure set up like this:

Dim EarnedPay As Decimal
End Structure

How to set these operations up?
I have classes that get the connection string the the .config file through ConfigurationManager. They work great in the actual application. When I use them in a unit test with nUnit I recieve an 'Object referance not set to an instance of an object'. I also tried to see if nUnit would read a ConfigurationManager.AppSetting and it failed too. Is there a configuration or workaround for this?

I been working on a Printer INK Management Program for my Company. We have many different districts we deal with. Each district has a different Server.I am trying to create the application where they can place the database file anywhere they would like on the server and when they first run the application it would ask them to choose the location of where they placed the file.I would like to know how i would be able to edit the connection string information in the app.config file during run time.

I'm writing an application that will be used to generate reports from a database and I want to have several predefined reports/queries built in but also offer the user the option to create their own query and be able to save it and run it whenever they want without having to set the query up again each time.
So I figured I would just store the query parameters in an XML file for the ones that a user has created themselves and I would store these XML files (one for each query) in the user's Application Data folder.
I'm wondering what I should do with the built in queries though (bear in mind that the parameters of these built in queries should not be configurable). As I see it, these are my options:
1. Have the query parameters hard coded in the application
2. Store the query parameters in XML files in the location where the app is stored (ie Program Files) - the installer would create these files when the app is installed
3. Store the query parameters in XML files in the user's Application Data folder with any queries they have created themselves.
I'm leaning towards option 2 for the following reasons: All queries (user defined or predefined) would then be in the exact same format and the program could then run them all in the exact same way. Option 1 would mean I would have to release a new version of the application if I ever wanted to change these parameters. Option 3 would mean that the program would have to create the XML files each time it was launched by a new user so it would be a bit pointless and the values for the parameters would still have to be hard coded in the application so that it could create the files correctly.
I've been getting this error when I try and use my model container:
No connection string named 'PFModelContainer' could be found in the application config file.
I have my edmx file in a separate project. I checked the app.config file and my model was there, and I also put it in my main project app.config file. Still doesn't work. Here's the connection string:
<connectionStrings>
<add name="PFModelContainer"

I'm using vs2010 and can't get this to work. The same code has worked in earlier versions. What has changed?
config file:

How to do this now?
I have a question about the App.Config file. My understanding is that the connection string is stored within this file. I have setup my application so that the App.Config file is not only written to c:users<username>appdatalocal but also to c:users<username>appdataoaming. I plan to encrypt the connection string, my question at this point is will it encrypt the connection string in ALL copies of the App.Config file? It looks like at this point that the App.Config file is stored in two places on the hard drive.
