fSaveBuffer (Function)

In french: fSauveBuffer

Creates and fills an external file with the content of a string or buffer variable. If the file already exists, it is deleted and re-created.

Remarks:

The strings containing binary "0" ("\0") are supported.
the created file is always in ANSI format.
The buffer variable is filled by fLoadBuffer.

Example

MyBuffer is Buffer
...
fSaveBuffer("c:\tmp\MyFile.raw", MyBuffer)

Syntax

<Result> = fSaveBuffer(<File to create> , <Content>)

<Result>: Boolean

True if the operation was successful,
False otherwise. To get more details on the error, use ErrorInfo with the errMessage constant.

<File to create>: Character string

Name and full (or relative) path of the file to create. A UNC path can be used. The file extension determines the type of file to create.
The file path can correspond to a full path or to a path relative 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 can only write to its setup directory or one of its subdirectories.
The file path can correspond to a full path or to a path relative 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 can only write to its setup directory or one of its subdirectories, as well as to 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.

Remarks

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).

In Windows Vista (and later), with the UAC mechanism (User Account Control) enabled, you must have administrator privileges to handle and/or modify the files or directories in 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 to the Windows directory or to the "Program Files" directory,
use the system directory of the application (returned by SysDir with the srAppDataCommun constant, for example).

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.
