LastErrorCode

Miscellaneous functions

Description

Use this function to determine the reason certain functions failed.

Reading the value is destructive: the function returns the stored error code and resets it to zero, so a second call right after a failure returns 0. Capture the result into a local variable before branching on it

Syntax

Delphi

Function TPDFlib.LastErrorCode: Integer;

ActiveX

Function PDFlib::LastErrorCode() As Long

int DLLastErrorCode(int InstanceID);
