Class Library Project Settings Just Disappear

I'm developing with VS 2008 in .NET 3.5 with Visual Basic.

My solution contains 3 Class Library projects and a Win Forms Application project.  Recently, one of the Class Libraries started mysteriously loosing its settings.  When I attempt to restore a value, the IDE erases it.  How can I fix this?

I would also like to know how bypass the project settings and use the Application settings instead?

Perhaps you are editing the file that is auto-generated instead of the config file. The regeneration would wipe out any changes you make.

I with it were that simple.  No, I'm editing the setting on the Class Project My Project sheet.

Are you talking about the settings on Settings page in project properties?

Yes, I am.  What would make the brand new setting (tested via elipsis ... button >> test connection button) to be rejected as soon as it is entered?  Here's an example:

Data Source=sqlserver;Initial Catalog=finance;Integrated Security=True

 Test Connection was successful

Show us a screenshot of the Settings tab as well. Does it happen to a newly created setting as well? Check to make sure the app.config file is not marked as readonly.

The top image is after adding the connection string.  I left the tab and returned.  The lower image is what results. Checked the App.Config too with Explorer and it is not read only.

Sorry for late reply. Try adding a string type setting and see if it works.

That seems to work!  I've changed all the Connection Strings to String and it works fine.  Why?  And why do my other projects not have a problem with Connection Strings working?  Is there a setting somewhere that can reverse this behavior?

I have no idea why but I always store my connection strings as Strings in settings anyway.
