ErrorInfo (Function)

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.

Ejemplo

// Open the overview file
nFileID is int = fOpen(FileName, foRead)
// Check the file opening
IF nFileID = -1 THEN
	Error("Unable to open file: " + FileName, ErrorInfo())
	RETURN False
END

// 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
END
