Exception in DaoSchema

[lauxjpn]

I pulled your fix repo and it seems to resolve the issue I statet here. However something else breaks now: I get en exception from the class DaoSchema constructor line 52
_database = _workspace.OpenDatabase(dataSource, /* Exclusive */ false, /* ReadOnly */ true, string.Empty);:

The repro is exactly same as in the first post.

Inner Exception 1:
COMException: Not a valid password.

If this is not related I can also open another issue.

COMException: Not a valid password.

@xoniuqe The inner exception claims that your password is incorrect.

Are you using a database password (not a workspace password)?
If so, is it correct?

[xoniuqe]

@lauxjpn: Yes. I specify it with the property(?) "Jet OLEDB:Database Password=" in the connetion string.

[lauxjpn]

@xoniuqe Thanks for reporting this issue!

The actual issue is fixed with #72. However, I came across another issue (unrelated to this one) regarding database passwords and ODBC connection strings, where it is currently not clear whether we can solve this adequately, or whether we have to live with a workaround.

Thank you for your fast replies the last days, I will test this as soon as I can, but currently I am working on some other issue and may not do this before monday.

@xoniuqe No worries. Just report back to us when you got the time. I did test it, so it should work. We will merge it today, so we can get 3.1.0-alpha.1 officially out the door.

By the way, are you using the German OLE DB provider, or are the German messages an issue that we need to look into?

[xoniuqe]

@lauxjpn I am not sure about the reason for the messages. I am working with a german system so the OleDB provider should be also german.

[lauxjpn]

I am working with a german system so the OleDB provider should be also german.

@xoniuqe Thanks, just wanted to make sure that I did not accidentally made Jet use German libraries by default.

(I am running an English system, but am German and have German region settings enabled, so it would have been possible that I referenced a local library somewhere.)
