Winforms - .net Connection Entity Framework Connection String Security?

Sep 3, 2011

I understand the possibilities for encrypting a connection string in .net v4. I have a win forms application that will be used by multiple people on different machines. I understand that I need to protect the connection string at time of the app being first run on the target machine. However I am concerned that for a period of time my connection string will be unencrypted. I am looking for advice in how to deploy my app with the connection string already encrypted or encrypted during installation. encrypting the connection string in a secure way?

Invalid Connection String When Modifying Tableadapter Connection?

Jan 19, 2011

I'm developing an app in vb.net (visual studio 2008). I have a Teradata back-end that will be supporting multiple users in a production environment. I need to use variables in the connection string as the user/pass will be changed every 3 months.

For the gist of the application:

In it's most basic form - I have a search form which works correctly - it pulls results into a listbox and the user then double clicks the list box which will then open a form that is bound via table adapter to the back-end table (Teradata). My connection string is fine everywhere in the application. My problem is using a modified connection string for the "fill" function of the table adapter once the form is opened.

I'm using the code below for the on-load event and keep getting an "invalid connection string" - again, the connection string works fine everywhere else in the app, and the variables etc... are working correctly.

Private Sub adaptertest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim DBConnStr As String = "Provider=TDOLEDB;Data Source=TDDEV;Persist Security

Connection String In Application Settings

Jan 14, 2010

I'm trying to give my users the option to move their database to a different location, currently the datasource is set as an (Application Connection String) in the Project Settings, I know that when the scope is set to "Application" it cannot be modified but I'd like to know if there's a way for me to edit the location through code of my database in the application settings without crashing the program, can this be done? The purpose is to give whoever uses my application the freedom to choose where the database should be.

Settings Is Readonly/ Changing Connection String?

Mar 2, 2006

This is regarding a windows app in Visual Studio 2005, a VB Windows application.'ve stored a connection string called strSQLConn in My.Settings. I'm trying to change the Server in code. I set a string variable called strConn to a new Connection string. My.Settings.Profile2006sql = strConn

This produces an error saying that My.Settings is readonly. I'm missing something basic here.

I don't know if this is the best way to change a connection string to toggle between a development server and a production server. My understanding is that if the setting Connection string is changed it will be used as the default for all the table adapters in a strongly typed dataset. Is that the case?

Change Connection String Saved In My.Settings In Program?

Jan 30, 2012

I am writting an application and I used Wizard to create DataSets which auto-created their own xml code. This code uses the saved in My.Settings Connection String. Being a setting with an unchangable 'Application' scope i cannot change its value at runtime.

The problem is that when I install the Application to my customer the Connection String will have to change (maybe more than once). So is there a way to change the Connection String used by these objects at runtime ?

Storing A Database Connection String Into Settings In A .net DLL Data Layer?

Mar 4, 2011

I've always used this approach while implementing data layer DLL for web application:

1) put datasets into the dll project
2) use a helper class with a method like this:

public shared sub settCnnStr(strconnhere as string)
My.Settings.Item("connectionString") = strconnhere
end sub

3) when I need to use the dll I call a method like this (usually into global.asax):

xxxxxxx.helper.setCnnStr("yyyyyyyyyyyyyy")

This method always worked for me nicely but I'd like to know if this method could have serious drawback or if there's a better solution.

VS 2008 - Store The Connection String In A Settings Table In The Database?

Apr 20, 2010

I am storing my connection string in my app.config file. I am using sql server express 2005. The connection string on my dev machine is different from the ones at the clients. so each time I update I open the config file and edit the connection string setting. This is quite a pain.also I have now published my app to an ftp folder so that the clients can get the updates each time I make changes. saves me the hassle of going to them each time i update. so now i need it to be so that I won't have to change the setting all the time.Would the best way be to store the connection string in a settings table in the database?

Networkstream Connection Fails & Httpwebrequest Connection Not Reading Fast

May 17, 2012

I am connecting to a data stream that pushes data continuously and when I tried to set up a network stream I just could not connect and kept getting the 'not found' error. I used the httpwebrequest with webrequest.keepalive = true and started to consume the data by reading into a buffer and then appending to a stringbuilder. Once the stringbuilder reaches max size I flush it to a text file. The problem is that I get disconnected from the data stream because I am not reading the data fast enough. I need to keep the connection open and read the data while ensuring data gets stored in text files. If I use method "CONNECT" it does not connect to the stream.

While (True)
webrequest = DirectCast(Net.WebRequest.Create(url), HttpWebRequest)
webrequest.Credentials = New System.Net.NetworkCredential(username, password)
webrequest.Method = "GET"

[code]....

should I increase the buffer size and if so what is the max? that would mean I can read more data at a time and keep up with incoming push. Disparate here.

ACtually also I noticed that it gets stuck on this line

numbytesread = responseStream.Read(bufferread, 0, BUFFER_SIZE)

and then eventually I get disconnected.

Changing The Connection String?

Dec 15, 2011

I'm trying to change my connection string to w/e the user wants. After a few tips here and there, this is what I've come up:

1: In my settings I've added - Name(login), Type(String), Scope(User), Value(Nothing)

2: Here is the code I'm using

Private Sub LoginForm1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Here I'm checking if the login in my.settings is there
'If not, I'm going to let the user choose what database

[code]....

The error I get is: Format of the initialization string does not conform to specification starting at index 0.here -

Dim con As New OleDbConnection(My.Settings.login)

When I have my con equal to when I added the datasource from it works.

Connection String For Sql Server ?

Apr 19, 2012

I have installed sql server 2005 in my machine which is installed vb.net 2008. I want my machine to distribute the database to the clients and make it as server.I don't have that much knowledge of how to overcome this issue as i am awfully naive about it.Let me start it here:I have got an application in vb.net...at first i was using ms access database 2007. then decided to switch on to the sql server since i want to distribute the database to the clients who are going to use my application.When i installed the sql server, i imported my access db files onto sql server database. i enabled tcp/ip as enable in the sql server network Configuration. i want use sql server windows authentication as my default user account of my system for the sake to simplify the issue.

Hence, i connected the sql server into the vb.net through the "add new data source".am done with that...the problem is how do i assign the connection string to the vb.net? Or how do i include a connection string in vb.net which tells every other computer that the database data source is in my computer so that every computer can automatically check it in the network.Where exactly shall i put the connection string...as far as my knowledge is concerned for access database, you can easily identify your connection string in project /properties/settings...it goes here and you put your database in any where.And what is the best connection string do i need for sql server 2005..computers are running windows xp.
