How to delete a data controls artifacts

Greetings everyone.
I am writing .Net (VB2010) windows application that retrieves data drom an Access Database and I have a Combobox for which I have set the data source using DataAdapter. When this is done Visual Studio places some control below the Form[Design) - eg CommercialDbDataset, Project_MasterTableApapter and ProjectMasterBindingSource.

I am not sure what I have done but when I run (debug) the program I get 101 Build Errors - all generated from CommercialDbDataset.Designer.vb and I have NO CLUE as to how to even begin fixing them.

I figured that if i could delete all these artifacts and re-assign the DataSource i could solve my problem.

Does anyone know how I could safely go about doing this?

Any assistance would be truely appreciated.

Good Morning Thanks for the responses. OK, I'm not too good at this (I am 2 weeks old in the .net world, I only know VBA and this is my first post ever) - I'll start over.

I am writing with Visual Studio 2010 Professional using only Visual Basic (Windows Applications). I also have an Access 2007 Database (.accdb) After placing combobox on the form, if you then view the combobox properties there is a DataSource property. If you click on 'Add Add Project dataSource' a wizard allows you to select the database (Calleed CommercialDb.accdb) and it sets up a connection and an SQl statement so that at runtime the combobox is populated with the field from the table that was selected during the 'wizard run' mentioned earlier. Wizard then places 3 controls on the form (not directly on it but underneath in a grey shade area below the form) called CommercialDBDataset, AuthoritiesBindingSource and AuthoritiesTableAdapter (Authorities being the name of the table within CommercialDB). Now my application has a parameter file which contains the path to the Database. this is use to build trhe connection string for other connections to the database. I have a test Database and a production database (the parameter file specifies which one the application should use). The path to the database in the controls that were created for the combobox Datasource are 'hard coded' so i got smart amd tried to change them - this resulted in the 101 errors (all reported from a ton of genetrated code that i could never possibly post on this site and it would largely be a waste of time because it is generated code. what i was hoping to do was delete the controls created by the datasource wizard, thereby delete the genetated code, and start again with the wizard. i am afraid to simply delete these things because i could end up with no program at all whereas i can still see my own code at the moment (although i cannot run the program) my question then is, how can i, if at all possible delete these controls (which i previously refered to as 'artifacts' your advive would be much appreciated because this is a fairly large program and I can't afford to lose it. thanks again
