Example
MyBuffer is Buffer
...
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.
Windows Mobile This path must be a full path or a UNC path. It cannot be a relative path.
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.
Reminder: Only the files found in the data directory associated with the application can be handled.
iPhone/iPad The file path can correspond to a full path or ot to a relative path in relation to the current directory (returned by fCurrentDir). This parameter is case sensitive.
Reminder: On iPhone/iPad, the file system is read-only on the device and on the emulator. An application has the rights to write into its setup directory or into one of its sub-directories.
AndroidAndroid Widget The file path can correspond to a full path or ot to a relative path in relation to the current directory (returned by fCurrentDir). This parameter is case sensitive.
Reminder: In Android, the file system is read-only on the device and on the emulator. An application has the rights to write into its setup directory or into one of its sub-directories, as well as onto the external memory (SDCard).
<Content>: Buffer variable or Character String variable
Name of the Buffer or Character String variable that constitutes the content of the file.

Operating mode in Windows Vista (and later)

If this function does not operate properly in Windows Vista (and later), check whether the file used is not found 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 found in the system directories (Windows directory or "Program Files" directory).
Programming tip: To handle and/or modify the files without having 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).
Note: 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.
