_DROPPEDFILE - QB64Official/qb64 GitHub Wiki

The _DROPPEDFILE function returns the list of items (files or folders) dropped in a program's window after _ACCEPTFILEDROP is enabled.

Syntax

Syntax 1

nextItem$ = _DROPPEDFILE

Syntax 2

nextItem$ = _DROPPEDFILE(index&)

Description

• After _ACCEPTFILEDROP is enabled, once _TOTALDROPPEDFILES is greater than 0 the list of dropped items will be available for retrieval with _DROPPEDFILE
• When using _DROPPEDFILE to read the list sequentially (without specifying an index&), an empty string ("") indicates the list is over and then _TOTALDROPPEDFILES gets reset to 0.
• When using _DROPPEDFILE with an index (which goes from 1 to _TOTALDROPPEDFILES), you must call _FINISHDROP after you finish working with the list.
• Because it returns a string, _DROPPEDFILE also accepts being followed by a string suffix (_DROPPEDFILE$)
• Keywords currently not supported.

Availability

• Version 1.3 and up.

Example(s)

Accepting files dragged from a folder and processing the list received by specifying an index.
