Usage:

BUTIL COPYFILE source ; target

Parameters:

source

The file name (and path) of the file being copied.

target

The name of the target file or directory to copy to.

Result:

0 for success or non-zero errorcode.



DELETEFILE

Delete the file filename.

Usage:

BUTIL DELETEFILE filename

Parameters:

filename

Result:

0 for success or non-zero errorcode



DIRECTORY

Selects a new working working directory (if dir is supplied) and returns the full path of the working directory.

Usage:

BUTIL DIRECTORY [ dir ]

Parameters:

dir

The new working directory.

Result:

The full path of the current or selected working directory.



DIRECTORYDIALOG

Display a directory selection dialog and return the selected directory path. If subdirs is set to Yes (1) a check-box for sub-directory processing is displayed.

Usage:

BUTIL DIRECTORYDIALOG caption [; path ; restore ; subdirs ; subflag ]

Parameters:

caption

The dialog window caption.

path

The default directory or * for the current working directory.

restore

Restore the current working directory (No|Yes). If No, the current working directory is set to the selected directory. The default is No.

subdirs

Show the sub-directory checkbox (No|Yes). The default is No.

subflag

The state to initialize the sub-directory checkbox to (Off|On). The default is Off.

Result:

An empty string (if the dialog was cancelled), the selected directory (if subdirs=No) or the selected directory and the subflag ('directory;subflag'), if subdirs=Yes. The value of subflag equals 0 or 1.



FILEDIALOG

A dialog to open (mode = OPEN|LOAD) or create (mode = NEW|SAVE) a file is displayed. All 'type=text' assignments are added to the filetype combo-box. The type "*=all files" is always appended to the type list. If the function returns a file path, all checks for opening and/or creating the file are performed, but the file is not opened or created! If a file is opened or loaded (type = OPEN | LOAD) only existing files can be used. It must be possible to open the selected file for read access. If a file is created (type = NEW|SAVE) it is tested to see if it exists already (an overwrite dialog is displayed) and if it is possible to open the file for write access.

Usage:

BUTIL FILEDIALOG mode [; caption ; defFile ; type=typetext ; type=...]

Parameters:

mode

The file dialog mode OPEN (=LOAD) or NEW (=SAVE).

caption

The file dialog window caption.

defFile

The default file name. The default file is selected when the dialog is displayed (if it exists). If no default file is specified, the dialog is initialised with the present working directory (PWD).

type

The file extension.

typetext

The description of files with extension type.

Result:

The full path of file or empty string for cancel.

Examples:

butil filedialog open ; Select a settings file ; J:\data\settings.xml ; xml=xml settings file 



GETDIRECTORY

To specify the x/y window position in pixels, a positive or negative number can be used. If x/y is greater/equal zero it is the offset from the left/top side of the desktop, otherwise (<0) it is the offset from the right/bottom side.

Result:

Name of button or one of the keywords CANCEL (if the window was closed) or TIMEOUT (if the maximum timeout value was reached). Note that user-defined buttons using the ampersand '&' to underline a letter (e.g. &Segment) return the keyword including the ampersand.
