Connection String For Teradata Backend
Jan 11, 2011
I'm really struggling here - I'm trying to create a connection string to my TD backend and this is not working unless I create a data source in the project and enter my username & password. (to be stored in the config file?) I just want a simple connection string that will allow me to perform updates - furthermore i would like it to prompt the user for a password initially. I keep receiving the error:"No error message available, result code: DB_E_ERRORSOCCURRED(0x80040E21)" [code]

I am wondering what I should use to connect to TD via VB.NET. Whether or not I should use ODBC, etc.My server is TDDEV, database BCPM_DDBO. Also, passwords are changed every so often by DB Admin so I would not want to hard code a password in the connection string. I know that ODBC will prompt for user/pass. Is this the route to go?

I'm sure there is a pretty simple answer to this, or at least I hope there is.I've created a data source (Teradata table) and opted not to save any username or password info when doing so with the "Add data source wizard" the reason for this is because the passwords change every 3 months. I have a form that is bound to the data source (teradata database) but when opened i receive the message "[Teradata Database] [8017] The UserId, Password or Account is invalid." because there is no username or password data saved. For example, i can open a linked table (the same table) via access and i'm prompted to enter a password (ODBC connection).

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?

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

Why doesn't an exception get thrown when this function is called when there is no ConnectionString set for the Connection? I just spent 15 minutes debugging and staring at it and finally figured out it needed the connection string. Shouldn't an exception get thrown?

I have to use VB.Net. Microsoft provides black magic tools (in the Visual Studio IDE) for making AJAX work, but using these seems hopelessly complicated and documentation for these tools covers only the simplest examples. By contrast, writing the scripts myself seems much easier, and I will understand what is going on.
So my question is, is it possible to write my own AJAX javascript (creating the XMLHttpRequest object, etc.), and have the server-side function be written in VB.Net instead of PHP?

I'm trying to create a proxy for cross-domain AJAX POST queries and, in order to do that, I need to be adding the cookies from my client (browser)'s request into the POST request I send to the PHP backend, which is using HttpWebRequest. In order to do this, I'm adding each of the Request.Cookie into the HttpWebRequest.CookieContainer object. For some reason, none of the cookies I add to it ever get to my PHP backend.
I understand from some searches that the CookieContainer object is URI-dependent (I'm not sure how to even explain it!), so perhaps that's the cause of my issues. However, I've tried setting the domain on my cookie to different things and it doesn't seem to affect it. So maybe URI means something different than the Cookie's Domain parameter. If that's the case, I'm stuck.

Right now all that is happening is that onclicking the button the thickbox closes, but how do i send data to .vb file in backend?

I am developing a software which will connect to a SQL SERVER situated at Head Quarters over a VPN connection.But for times when VPN is disconnected I want my applications at the branches to connect to a local Sql Server installed at a local server.Now all the applications at each of the local machines have their connectionstring stored in their App.config file.When the VPN is disconnected we have to change each of the connection strings on all the applications in each machine. Is there a way to do it automatically switch the connection string depending on whether the Server is reachable or not, and to store the connectionstring at centralised location.

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.

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.
