How do I use the ASP error component?

The error is first obtained by the set Objasperror=server.getlasterror and then by the owner of the ASPError object to obtain the relevant information:
objASPError.ASPCode: Returns the error code generated by IIS
Objasperror.number: Returns COM standard error codes, such as 0X800A03FC
objASPError.Source: Returns the original code that actually generated the error
Objasperror.category: Indicates that the source of the error is ASP, script, or object
objASPError.File: Returns the wrong program file name
objASPError.Line: Returns the line number of the error program
objASPError.Column: Returns the number of columns in the error program
Objasperror.description: Return error source cause introduction
objASPError.ASPDescription: Returns detailed error reason
