fSaveText (Function)

The created text file is always in ANSI format, regardless of the platform used (PC, Pocket PC, ...). To create a text file in Unicode format on a Pocket PC, use fOpen or fCreate (see the notes).

FileContent = fLoadText("C:\Sales\FrancPrices.txt")
FileContent = Replace(FileContent, "Franc", "Euro")
fSaveText("C:\Sales\EuroPrices.txt", FileContent)

// Fills the file with the content of a variable

fSaveText("\Customers\LastFirstName.txt", EDT_LASTN_FIRSTN)

FileContent is string
FileContent = fLoadText("\Sales\FrancPrices.txt")
FileContent = Replace(FileContent, "Franc", "Euro")
fSaveText("\Sales\EuroPrices.txt", FileContent)

Syntax

<Result> = fSaveText(<Name and path of the 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.

<Name and path of the text file>: Character string (with quotes)

Name and full (or relative) path of text file to create. A UNC path can be used.
Versions 15 and later
This parameter can be in Ansi or Unicode format.
This parameter can correspond to a full path or 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 subdirectories, as well as onto the external memory (SDCard).
New in version 15

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).

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.

Equivalence

fSaveText is equivalent to the following code:

// Opens the file in read-only
f is int = fOpen("C:\MyFile.txt", foCreate)
// Writes into the file
FileContent is string = "example of text"
fWrite(f, FileContent)
// Closes the file
fClose(f)

Equivalence

fSaveText is equivalent to the following code:

// Opens the file in read-only
f is int = fOpen("\MyFile.txt", foCreate)
// Writes into the file
FileContent is string = "example of text"
fWrite(f, FileContent, Length(FileContent)*2)
// Closes the file
fClose(f)

Remark: The text file created by fOpen or fCreate on a Pocket PC is in Unicode format. The text file created by fSaveText on a Pocket PC is a file in ANSI format.

Component : wd250std.dll
