I am trying to use Result from AfterExecuteWindow.

procedure AfterExecuteWindow(WindowType, Result: Integer);
begin
ShowMessage('AfterExecute ' + IntToStr(WindowType) + ' ' + IntToStr(Result));
end;

According to plugin documentation I should get 0,1 or 2 as Result. However, when I open an SQL window and execute a successful or erroneous query, I always get the following output, what am I doing wrong?

AfterExecute 1 1702356

Can you let me know if you are using a 32 bit or 64 bit version?

32 bit

To obtain some more diagnostic information, can you modify the PL/SQL Developer shortcut and add the DebugSQL parameter? For example:

"C:\Program Files\PLSQL Developer 13\plsqldev.exe" DebugSQL

Reproduce the problem and send me the debug.txt file that is generated in the %APPDATA%\PLSQL Developer 13 directory (e.g. C:\Users\<User>\AppData\Roaming\PLSQL Developer 13).
