GetLastError()

Summary

Gets the text of the last error generated by Maptitude.

 

Changes

The default value of the Reference Info option changed to "False" in Version 5.0.

 

Syntax

text = GetLastError(array options)

 

Option	Type	Contents
Reference Info	Boolean	"False" (default) to have reference information, otherwise "True"

 

Returns

A string containing the text of the last error message, or null if there is no error message.

 

Notes

• Use GetLastError() to get an appropriate message when trapping errors.

• GetLastError() may not return an appropriate message if it is called after a Caliper Script function has returned successfully.

• If the Reference Info option is "False" only the first part of the error message is returned. The "Click OK to continue" and "Reference info:" parts are not returned.

• If the Reference Info option is "True" you can toggle whether to show the reference information with SetReferenceInfo().

Example

on error do

     ShowMessage(GetLastError({{"Reference Info", "False"}}))

     Return()

     end

CreateBuffers(...)

on error default
