The wwScripting class provides a simple mechanism for executing ASP style script pages containing Visual FoxPro code. The class provides a mechanism for dynamically executing script templates including full semantics for compilation and runtime version checking to provide optimal execution performance as pure FoxPro code.

Code execution runs against ASP style script which can evaluate script expressions (<%= %>) and full code blocks (<% %>). The script parser converts templates into pure FoxPro source code that is executed either from a PRG/FXP file on disk using the RenderAspScript method or from memory using the ExecScript method.

The wwScripting class is used as the script parser for Response.ExpandScript and generic script execution in the Web Connection Framework.

Class Members

Member		Description
	ExecScript	This method is used to execute a script template using the FoxPro ExecScript command. This method can accept input from a file or from a string that holds the ASP style template. o.ExecScript(lcTemplate as string, llIsCodeString)
	MergeText	Provides Template parsing for expression evaluated tempaltes. Unlike script pages, MergeText evaluates pages by parsing each script block individually and executing the code contained in it. Uses EVALUATE for <%= %> expressions and EXECSCRIPT for <% %> blocks. o.wwScripting.MergeText(lcText,llIsFile)
	RenderAspScript	Renders an ASP style page as a compiled VFP program. This method handles creation of the VFP source code from the script file, compilation and checking for updates of the file. o.RenderAspScript(lcTemplate)
	cCompiledPath	Path where our compiled FXP and WCT files are stored. Defaults to the same path as the template.
	cErrorHeader	This property can be used to display the top of the error message page should a scripting error occur.
	cErrorMsg	An error message if the script execution fails. Also set is the lError property.
	cScriptCode	The input script code saved to a variable.
	cScriptResponseClass	The Response class used for script processing. wwScriptingResponse This is the default Response class used that provides the base functionality. It includes functionality for writing output and clearing output.
	cVFPCode	The generated VFP code saved for you to review.
	lEditErrors	If .T. pops up an editor window for editing the error in the code.
	lError	Error flag that can and should be checked after running a script or template. You can also check the cErrorMsg property for a string error message.
	lNoVersionCheck	If .T. doesn't check or attempt to compile the file, but just executes the FXP. Assumes the FXP exists and fails if it does not exist.
	lSaveVfpSourceCode	If .t. doesn't delete the generate VFP source code after compiling
	lShowFullErrorInfo	If .T. displays full error information on the page if possible
	lStopOnError	Flag used to cause parser to stop on the line of code causing error in VFP
	oException	A VFP 8/9 Exception object which is set when an error occurs. Usually you don't need to look at this as the cErrorMesage
