I found the code at the end of this post while trying to learn about
drag and drop to an Air app.
It looks like it should do what I want, but generates two errors that I
have been unable to solve (I am still very much a newbie).
the errors are:
[SWF] DragDrop.swf - 1,284,532 bytes after decompressionError #2044:
Unhandled IOErrorEvent:. (2044 Unhandled %1:.) text=Error #2038: File
I/O Error. (2038 File I/O Error.) at
flash.desktop::Clipboard/getFileList() at <anonymous>() at
flash.desktop::Clipboard/convertNativeFormat() at
flash.desktop::Clipboard/getData() at DragDrop/onDrop()[D:\tex\My
Documents\Flex_Builder_3_Projects\DnD\OriginalDragAndDrop\src\DragDrop.m\
xml:41] The error seems to be pointing to the private onDrop function.
Can anyone offer any suggestions?
many thanks in advance, Tex
