SAMPLE: 4thScrpt.exe Demos Active Debugging in ATL ActiveX Script Engine

• Microsoft Visual C++, 32-bit Editions, versions 5.0, 6.0

SUMMARY

The 4thScrpt.exe sample demonstrates how to implement Active Debugging in an ActiveX Script Engine built with Active Template Library (ATL). The sample is designed to supplement the Active Debugging documentation available on the Microsoft Developer Network (MSDN).

This sample demonstrates how to add Active Debugging support to an ActiveX Script Engine. Active Debugging builds on Active Scripting and enables debugger host applications, such as Microsoft Script Debugger, to provide comprehensive, language-independent testing, and error correcting capabilities. Functionality, such as breakpoints, expression evaluation, and data monitoring, are all possible through the Active Debugging interfaces. Active Debugging also makes it possible to debug multiple scripts in different languages concurrently, making cross-language issues easier to locate and correct.

To Compile the 4thScrpt.exe File

1. In Visual C++, add a new include directory by clicking Options in the Tools menu. Select the Directories tab, and show directories for Include files. Click in the Directories window, and then add a path to the Scripting folder of this sample. Drag this path to the top of the list so that it is checked first.



2. On the Directories tab, show directories for Library files. Click in the Directories window and add a path to the Scripting folder of this sample. Drag this path to the top of the list so that it is checked first. This folder contains headers and libraries needed to compile Active Scripting and Active Debugging projects.



3. On the Project menu, click Settings and then click the Link tab. In the Object/Library modules, make sure that the Ad1.lib file is referenced. This file contains GUIDs necessary for Active Debugging.



4. Build the project. You need to modify the Objsafe.h file in the Visual C++ Include directory if you get the following error messages:

   error C2065: 'INTERFACE_USES_DISPEX' : undeclared identifier

   error C2065: 'INTERFACE_USES_SECURITY_MANAGER' : undeclared identifier

   Find the definitions for the Option bits for IObjectSafety, and add definitions for INTERFACE_USES_DISPEX and INTERFACE_USES_SECURITY_MANAGER, as shown below. These bits are required by Internet Explorer.

   
      // Option bit definitions for IObjectSafety:
      #define	INTERFACESAFE_FOR_UNTRUSTED_CALLER	0x00000001
         // Caller of interface may be untrusted
      #define	INTERFACESAFE_FOR_UNTRUSTED_DATA	0x00000002
         // Data may be untrusted
      #define	INTERFACE_USES_DISPEX	            0x00000004
         // Object knows to use IDispatchEx
      #define	INTERFACE_USES_SECURITY_MANAGER	    0x00000008
         // Object knows to use IInternetHostSecurityManager 



Once the project has compiled, the engine registers itself. Please see the ForthScript.txt file for more information about this sample.
