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
