m_cnADONetConnection.ConnectionString =

"Server=113.30.141.10:1433;" +
"Database=CorporateDatabase1;" +
"Integrated Security=false;" +
"Connect Timeout=30;" +
"User id=sa;Password=password)";

but it gives error as

Why do you include port into ip address of server, it's wrong. Port should be added to intitial catalog(DB Name)
m_cnADONetConnection.ConnectionString =
"Server=113.30.141.10;" +
"Database=CorporateDatabase1,1433;" +
"Integrated Security=false;" +
"Connect Timeout=30;" +
"User id=sa;Password=password)";
