Reports and Queries

Operating mode in Windows Vista (and later)

If this function does not operate properly in Windows Vista (and later), check whether the file or directory used is not in one of the system directories (Windows directory or "Program Files" directory).
Indeed, in Windows Vista (and later), with the UAC mechanism (User Account Control) enabled, you must have the administrator privileges to handle and/or modify the files or directories in the system directories (Windows directory or "Program Files" directory).
Programming tip: To handle and/or modify the files or directories without administrator privileges, you should:
  • avoid writing into the Windows directory or into the "Program Files" directory,
  • use the system directory corresponding to the application (returned by SysDir associated with the srCommonAppData constant).
Component : wd250std.dll
Minimum version required
