In this PowerShell example, the trap clause catches the exception being thrown and swallows it by continuing execution. The "I should not be here" message is shown as if no exception had happened. &{ trap { continue } throw write-output "I should not be here" }
Restrict functions to a single printed page. Use a minimum of two runtime assertions per function. Restrict the scope of data to the smallest possible. Check the return value of all non-void functions, or cast to void to indicate the return value is useless. Use the preprocessor sparingly.
Microsoft supports SEH as a programming technique at the compiler level only. MS Visual C++ compiler features three non-standard keywords: __try , __except and __finally — for this purpose. Other exception handling aspects are backed by a number of Win32 API functions, [ 2 ] for example, RaiseException to raise SEH exceptions manually.
PowerShell is a task automation and configuration management program from Microsoft, consisting of a command-line shell and the associated scripting language.Initially a Windows component only, known as Windows PowerShell, it was made open-source and cross-platform on August 18, 2016, with the introduction of PowerShell Core.

Windows implements software DEP (without the use of the NX bit) through Microsoft's "Safe Structured Exception Handling" (SafeSEH). For properly compiled applications, SafeSEH checks that, when an exception is raised during program execution, the exception's handler is one defined by the application as it was originally compiled.
In computer programming, several language mechanisms exist for exception handling. The term exception is typically used to denote a data structure storing information about an exceptional condition. One mechanism to transfer control, or raise an exception, is known as a throw; the exception is said to be thrown. Execution is transferred to a catch.
For many of the above uses, Active Scripting is an addition to Windows that is similar to the functionality of Unix shell scripts, as well as an incremental improvement upon batch files (command.com), Windows NT style shell scripts (cmd.exe) and, by way of VBScript, the replacement for QBasic, which was last available on the supplementary disc ...
A VBX is a packaged extension in the form of a dynamic-link library (DLL) that allows objects to be graphically placed in a form and manipulated by properties and methods. These were later adapted for use by other languages such as Visual C++. In 1992, with Windows 3.1, Microsoft released OLE 2 with its new underlying object model, COM.
