I have been having trouble with a Database Table, in that I was updating it, yet when I looked in the ComboBox, the update wasn't showing up.

I have been told that it is probably because my Database was set to "Copy if Newer", so I have amended it to "Do Not Copy" but I am now getting a Build Error as follows ...

The database file cannot be found. Check the path to the database. [ Data Source = j:\Users\Gary\Documents\Visual Studio 2010\Projects\KA League Cup\KA League Cup\bin\Debug\KALC.sdf ]

The message isn't wrong, my database is not there, it is 2 Folders back (i.e. on the same path but without the "\bin\Debug" & that is what my Connection String says, so why is the program trying to look into the bin\Debug folder, which I guess is where it was stored when it was set to "Copy if Newer" ?!?!?

Help !!!

You need to copy your database to a fixed location and access it from there. You should only be doing the copying during the project development phase while the structure of your tables may be changing. Once you have the design right then use the fixed location database, so all updates will be saved in that file and it will not get destroyed while rebuilding your project.

OK, I understand what you are saying, conceptually, but am a bit confused by your wording, sorry Richard ! My Database is in a fixed location now and I am happy to access it from there until my testing has finished, but are you saying I should copy that to somewhere else and access it from there instead ? What about the Settings, should I have that set to "Do Not Copy" or "Copy if Newer" ?!? Some of this Visual Studio stuff is brilliant, but some of it is still so confusing !!!

As I understand it if you set to "Copy if newer", it should only copy the blank database to your execution directory if you change anything in it. Having had problems myself, however, I would suggest you move the final version to a directory that will not get overwritten and access it from there. You just need to change your connection string to the new location. You can try setting to "Do not copy" and see if that works OK.

OK, got the Database back, thanks, but I had to actually delete it and add it again as a new Source ... VS2010 is so clever & so stupid at the same time !!!
