I think ex.innerexception returns null value. Try below code try { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); //Application.Run(new mdiMain()); Application.Run(new SplashScreen()); Global.iniVar.sqlerror = false; } catch (Exception ex) { Task task = new Task (Test); Global.iniVar.sqlerror = true; String str = Error in SQL Server Connectivity; if (ex.InnerException != null) { str += ex.InnerException.Message; } MessageBox.Show(str); Application.Run(new mdiMain()); } If it helps you select it as correct answer.

Looks like there are no error raised in try block. Give simple message box at the end of try block and check. If try block completed or not.
