I solved it with this connection string.

m_Desktopconn = New SqlConnection(
  "Data Source=192.168.55.100,1433;Initial Catalog=Testing;Persist Security Info=True;User ID=sa;Password=sa;")

I had two instances MYPCSQL2005 & MYPCSQL2008, and then installed SQL 2005 Express on MYPC (Without instance)
