The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Changing connection string at runtime

Zones: Visual Studio .NET 2005, C# Programming Language, SQL Server 2005

Tags: Microsoft, Visual Studio 2005, C#, 2.0

I have read some of the solutions in this forum and looked at the MSDN help and cannot get this to work...

I am developing a Windows Form application in Visual Studio 2005. I want the database connection string to be modifiable at runtime. Now there are a couple of twists here:

1) This is all part of a Class library project, not my main application project.

2) My configuration file is not the standard Settings.settings. I have a separate settings file (I must do this, don't ask why), called "DBSettings.settings". When I do this, it generates the app.config file for my library (DLL) shown here in the code snippet.

According to the MSDN documentation, all I should have to do is replace the <connectionStrings> section with:
<connectionStrings configSource="connections.config"/>
This does not work. My app.config file is copied to the output directory, the connections.config file is.

My connections.config file looks like this:

<?xml version="1.0" encoding="utf-8" ?>
<connectionStrings>
<add name="CardioInsight.Lib.Database.DBSettings.DBConnectionString"
connectionString="Data Source=OTHERSYSTEM\SQLEXPRESS;Initial Catalog=CardioInsight;Persist Security Info=True;User ID=USERNAME;Password=PASSWORD"
providerName="System.Data.SqlClient" />
</connectionStrings>
