fSaveBuffer("c:\tmp\MyFile.raw", MyBuffer)
Syntax
<Result> = fSaveBuffer(<Text file> , <Content>)
<Result>: Boolean
  • True if the operation was successful,
  • False otherwise. To find out the error details, use ErrorInfo associated with the errMessage constant.
<Text file>: Character string (with quotes)
Name and full (or relative) path of file to create. A UNC path can be used.
Universal Windows 10 App Windows Phone: The file path corresponds to a relative path in relation to the current directory. The current directory corresponds to the data directory of application.

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).
Remark: In Windows Vista (and later), the virtualization mechanism is used to make the applications compatible with Vista. If the file is created in a system directory without having sufficient rights, this file will actually be created in another directory (C:\Users\<LOGIN>AppData\Local\VirtualStore\Windows\). In this case, the file cannot be shared between several applications.
