SQL Query Analyzer - How To Select and Execute a Line of SQL Using SendMessage() (1.1) or Other Trick

Hi
I want to select a line of text that I have inserted by way of SendMessage in another process and then execute it, but unable to do either.  I used Spy++ to see what is happening behind the scene and replicate similar messages but this approach yields no fruit.  Am assigning high level pts because this has frustated Jon, my Norwegian friend who claims to be best hacker. ha

1.  Run Query Analyzer and open a child query window
2.  Create a new C# windows application and copy the below code over the generated Form1.cs
3.  Run and click button
4.  Copies SQL ok and the down arrow is intercepted properly, but neither is text selected nor executed
