I have been creating a small winforms app using VS 2005 and SQL Express. I
create serveral tables in the database and added it as the datasource for th
e
project. I created several forms, created several datagrids and regular
design views. After I got several of the forms running, I decided to backup
my directory and copied the entire directory to a backup directory on my har
d
drive.
While continuing to work on my project, the IDE lost some of the data
adapters and and datasets while I was switching between the design view and
code view. So I decided to delete the directory and copy the backup I had
saved and start from there. But a Big Problem occured. Once I opned the
project and tried to execute it, I could no longer get the app to connect to
the database. I am the only user and administrator account but every time th
e
app tries to fill a table now I get on of these two erors:
System.Data.SqlClient.SqlException was unhandled
Message="Unable to open the physical file -- ". Operating system error
5: \"5(Access is denied.)\".\r\nUnable to open the physical file
or
System.Data.SqlClient.SqlException was unhandled
Message="Cannot open user default database. Login failed.\r\nLogin failed
for user
Source=".Net SqlClient Data Provider"
ErrorCode=-2146232060
Class=11
LineNumber=65536
Number=4064
Procedure=""
Server=".\\SQLEXPRESS"
State=1
StackTrace:
I can no longer connect to the database even thou I can see and work with it
in the IDE. Help
HWDotNetDeveloperSeveral possible reasons for this:
1) you did not restore your original LDF file with your matching MDF
2) you have not re-attached the database
3) you are trying to connect using an sql user account and it is not config
ured the same with the "backed" up version
4) you are trying to connect without the correct user instance reference (i
e. the backed up version is different from the one you deleted)
If you can see the database from the IDE, then using query analyzer and run
a test query. You can also start OSQL and run a simple query against the da
tabase. If these queries work, then there is something not synchronized wit
hin your code versus the database that was restored.
