Change Connectionstring Thru Setting?

Jun 29, 2009

I know below code causes an error since "Property 'AAConnectionString ' is 'ReadOnly". What other choice do I have to assign a value for a user ID or a password with a value of textbox by coding?

My.Settings.AAConnectionString = "Data Source=bb.allgood.com;Initial Catalog=aadb; Persist Security Info=True;User ID=aa123;Password=aa123"

Setting DataSource Connectionstring At Runtime?

Dec 22, 2011

I am kind of an old 'newbee' at this, so bear with me for a moment. I am developing a windows forms application in Visual Studio 2010 Professional that connects to a remote database (MS sqlServer 2008 R2).To speed up development, I configured a DataSource and used the data objects associated with it. In VB6,
the data source could be assigned to the data objects during runtime using a variety of different runtime database connections, ODBC, ADO, ...

I have been unable to find a similar method with the VS2010 Visual Basic DataSource and underlying TableAdapter, BindingSource, BindingNavigator, down to the individual ComboBox and assorted other bound controls. It's convenient to have the integration, but I've got different users with different permissions, The long and short is that I'd like to be able to assign the data source during runtime operation, at least to the connection string level.

Change Application Screen Size Setting

Jul 27, 2010

I am working on an application using vb 2008 express. I have built test programs over the past few weeks and shared them for feed back. Today when I finished some work, I built another test application, but when I install it the start-up screen maximizes but is set between one and two desktop icons from the top of the screen.

In debug mode it looks fine. In the past it looks fine. Each time I start the program the screen is in a slightly different location. It is set to start maximized and to the best of my knowledge, I did not change any settings in the property area. I have tried loading on three computers and the results are the same. Any ideas on what I could have done to produce this strange result?

Where To Place ConnectionString In DA

Jan 6, 2011

I designed a DAL (data access layer). This DAL mainly consists of a handfull of methods to call stored procedures. All methods are shared. So no instance generation of the DAL class occurs.

The DAL with it's single class is located in an own project. The connection string is defined in the app-config file of this project.

I want other applications to use the DAL class by referencing the dll generated by the DAL-project. For this reason, I can not any longer define the connection string in the DAL app-config as it is, because the client application determines which database needs to be used.

- Dropping the "shared" keyword of my methods. Create an instance of the DAL class. Add a property for the connection string. When application starts, create one global or multiple local instance/s of the DAL and set it's connection string property.

Comment: I don't like this, because it implies more coding work on the application code side (create instance of class, assign connection string)

- Granting the DAC class access to the connection string defined in the application code by adding a connection string property inside the application code. Thus the DAC class remains "shared".

Comment: I'd need to set a reference from the DAL to the application code during without knowing the application yet. I could try stack tracing or something like that. But it feels to convoluted for me.

ConnectionString In Class Library

Apr 27, 2011

I'm merging two of my projects that can share a lot of the same classes into one solution with two web applications and a shared class library.

I've literally just dumped all the classes into the class library project and as expected I've got a ton of errors to fix. My main problem at the moment is the connection string. Currently I have this (which is obviously not going to work):

''' <summary>
''' Initialise the data access layer by loading the database connection string from the Web.Config file

.net - ConnectionString Property Has Not Been Initialized?

Jul 15, 2009

I've looked at a lot of posts on different forums where others have received the same error. Most say they were not referencing the connectionstring from the web.config file correctly, or they were trying to open the connection before setting the connectionstring. Well, if that were the case for me, then how does it work on two different systems, but not on the third? It works on my development PC and on the development server, but not in the production environment. The difference is the web and DB server are separate physical servers in my production environment and on a single server for development. My setup, error message and code will be listed below.

I can simulate the error on my PC if I rename the connection string in either section of the web.config file (appsettings, connectionstrings) to something else. You will see how I have tested both below.

Changing Connectionstring At Runtime

Feb 18, 2010

Im writing a app using vb.net, which has multiple front ends e.g a windows service and a windows forms app. Ive got all my business logic and database stuff compiled into 1 project (producing a dll) then the different front ends as different projects calling the dll.

In the backend / dll project Im connecting to 2 databases using app.config to store the connection strings and DataSets / TableAdapters. This all works fine .... Until

When I deploy the windows app, it deploys the exe and the dll produced by the backend project. when its installed on a client PC, Im need to point the app at a different db server and therefore need to change the connectionstring, but its packaged up in the dll.

is there any way I can use a settings file within my windows app (therefore deployed with my windows app) where I can define the connectionstring, which onload gets passsed through into my dll, so the backend connects the correct database. I know how to pass standard settings through (strings etc) but the my.settings.connectionstrings seem to be readonly.
