How to Change Development Database in LightSwitch

September 27, 2011 3 comments

Last week I had an issue building my LightSwitch project on Windows 8 instance because it had SQL 11 express instance as the default DB instance on the computer. I then installed SQL Server 2008 R2 Express on the machine to make it build.

You may have noticed that LightSwitch doesn’t provide an intuitive way to change the instance of the Dev database. I have done the following to connect to the SQL Server 2008 R2 instance

Right click on the LS project

Unload project

Right click the project and click edit

Find SqlExpressInstanceName attribute

Replace the database instance with one you want to connect to. In my case, I replaced

<SqlExpressInstanceName>SQLEXPRESS</SqlExpressInstanceName>

With

<SqlExpressInstanceName>SQLEXPRESS2k8</SqlExpressInstanceName>

Right click the project and reload

ORA-01017: invalid username/password; logon denied

September 21, 2011 10 comments

Today I faced a not too funny challenge. We had to downgrade the oracle driver (i.e. ODP.NET) from version 11.2 to 10.2 and guess what? I got the “ORA-01017: invalid username/password; logon denied” error. It turned out that ODP.NET 10.2 and prior uses case insensitive passwords and will convert the password to upper case when connecting to the database.

To fix the issue we had to wrap the password with double quotes

Data Source=MyTsn; User ID=MyUserId; Password=”mypassword”

Windows 8: Mount VHD/ISO files


This is how my C drive looks like

I boot from 3 of the above vhd files plus the Windows 7 instance installed on the hard drive

I had to remember to copy the files I need to share across OS’s to the C drive. UNTIL Now J

In Windows 8 it is possible to mount a VHD file and treat it as a hard drive

Right click the vhd file and click mount

Notice the new created drive under My Computer

You can also mount ISO files with the same process

To unmounts, right click the drive or the DVD drive and click eject
