Using a form, from a dll, to maintain properties in My.Settings
Friends,
I have a document (attached to this question) that outlines the code I am using, and that some how I want to include in my other projects (as a dll). The end result, is that I want allow my users to update their data source names in the programs they use (which is what the dll is intended to do).
This works great for the Data Source Names (dsn) that are included in the dll's project, but if I include this project (as a dll), it won't reference the values in the parent program's My.Settings list. It is still looking for a list of My.Settings for the local project (dll).
By this, I mean that I run a program (ex. Project 1) that uses the DSNMaintenance dll. I want the DSNMaintenance.dll to look at Project 1's My.Setting list, and not it's own.
Now, I could just include the form from the project, and it works great, but, if I wanted to make a change to that form, I'd have to update it in every project I use.
What do I need to change in my DSNMaintenance project to expose the My.Settings list of the parent project that references the dll?
Looking for VB.net syntax help, please!
Thanks in advance!

In a nutshell, is this saying that I need to build my list of settings in my main project, and then pass that to my dll?
If so, can you help me with the building of the list to pass?

I think you can define a property in the DLL which you form can access so you set it equal to my.settings at runtime before showing the form.

Uh...sorry...a little more help, please?
You have to remember, I wasn't that great a developer before, and it's been two years since I've done this.
What goes where? My form is in my DLL, so I'm not sure which you are referring to.

Code Cruizer...
Is it possible that you haven't looked at my specific example? I appreciate that you help a lot of people, but I said from the beginning that I was looking for VB.net syntax help, and I would appreciate help for my specific example.
I am looking up all the Settings, that contain the string dsn, and then putting them into a list, not just a single know property as it seems in the link you gave me.
Does that help you to understand where I am coming from?
Best Regards,
Eric

Code Cruizer,
You there?

Yes. The code I wrote was mainly suedo code to give you an idea.
The main idea is that you need to pass the reference of your My.Settings class into the DLL somehow. So if you have a form in DLL, you need to define a public property on that form and then set this property to My.Settings at runtime before you show the form so that form is able access the settings indirectly.

Can you create the code for the Property? I'm not sure how to implement a property for the My.Settings as you describe. I think I might be able to figure out the rest after that.
I already did
Public Property AppSettings As Object
Its object because My.Settings is dynamic. You can still use the
AppSettings.MySetting = value
as you as you are sure that settings exists.

CodeCruiser,
Okay, let me be VERY specific...Can you write the rest of the Property code.
including the Get and Set, please.
