Retrieves information about the last error that occurred in a function of a WINDEV, WINDEV Mobile or WEBDEV component.
Caution:
  • ErrorInfo must be used immediately after the call to the function that failed. Indeed, calling a WLanguage function may reinitialize and modify the status report of ErrorInfo.
  • ErrorInfo should not be used to check whether an error has been encountered. To check if a WLanguage function has encountered an error, use one of the following methods:
    • check the status report of the WLanguage function.
    • check the ErrorOccurred variable.
Example
// Open the overview file
nFileID is int = fOpen(FileName, foRead)
// Check the file opening
IF nFileID = -1 THEN
Error("Unable to open the file: " + FileName, ErrorInfo())
RESULT False
END
WINDEVUniversal Windows 10 AppUser code (UMC)
// Error found?
IF ErrorOccurred = True THEN
// Full message of the main error
Trace(ErrorInfo())
// Browse the sub-errors (if any)
FOR i = 1 _TO_ ErrorInfo(errNumberSubError)
// Full message of each sub-error
Trace("Sub-error " + i + ": " + ErrorInfo(errMessage, i))
END

Getting information about the sub-errors of the last error Hide the details

<Result> = ErrorInfo(<Type of information> , <Sub-error subscript>)

Subscript of sub-error to use.
Reminder: The number of sub-errors for an error is returned by the errNumberSubError constant.
Remarks

Equivalence

Calling Error without any parameters displays the error message corresponding to the last WLanguage function that triggered an error.
In this case, the following code:
Error()
is equivalent to:
Error(ErrorInfo())

HFSQL error

When an HFSQL error occurs, ErrorInfo is equivalent to HErrorInfo.
