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.

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?

Changing A Connection String At Runtime For A Tableadapter That Was Created Using The Wizard?

Jun 21, 2010

I've created two forms of which two separate datasets/tableadapters were created by adding a datasource and dragging and dropping the fields onto my form.I was testing the program using a db that was located on my local drive. Well after publishing the app to the users machines, I noticed that the binded information was still being pulled from my local machine and not the database that the user is working off of.I've set the connection modifier properties for both tableadapters to Public, and I have written the following attempting to change the connection strings:

Private Sub btnSaveSettings_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSaveSettings.Click
Dim pap As New frmPap
My.Settings.dbLocation = txtSettings.Text

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 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

Changing A String To A Control?

Dec 1, 2010

I am reasonable new to programing and have ventured in to using VB.net after creating macro's etc in excel, as this seemed to be the easiest transition into the world of programing.I am creating a application to work with an access database and before I submit the forms textboxs to the database, I check to make sure each field is filled in and if it isn't then I highlight the field by changing the label back colour to orangered.

What I have is a bunch of textboxes and a label above each saying what the field is. so for example the textbox name is txtBox1 and its label is lblBox1, txtBox2 - lblBox2 and so on.So what I thought I would try and do is, as the user leaves the txtBox after editing, the label background colour would be changed back to transparent.

As I have multiple txtbox's I thought I could do this using sender to get the name of the txtBox on leave, strip the first 3 letters txt and change them for lbl cast it as a label, then change the background color but I cant seem to convert my string to a label control. can someone help me with what am i missing or not doing.

Why Is Textbox String Changing Lengths

Feb 26, 2012

I am working on a project that I scroll from one screen to another.

A particular string I have 2 variables that can be changed. If I stay on this screen I can change either variable just as I need

however when I change to another screen then return my string is 1 digit longer and when I wish to edit this string my program fails because the string isn't the expected length.

A portion of my program follows....The Y6 is just a counter. The MA is a conditional control.

ElseIf _
Y6 = 4 _
And MA = True _

[Code]....

Delete 0-27 then determine whats there "NC" or "NO" and simply change it. But again when I leave this particular screen and return my text length is no longer 29 charactors long, it is now 30 charactors.
