<div dir="ltr"><div dir="ltr">The correct way to load FFI is to load it from SqueakMap, update, in the mid left panel bring up the menu and unselect "New safely-available packages", and then install head. Answer yes to installling something not compatible with your current system (it is, just the map package hasn't been changed to say it is compatible).<div><br></div><div>Once this is finished, FFI will be loaded.</div><div><br></div><div>At this point, you still need to load the Win32 extentions. Open the Monticello Browser, click in the repository panel on the right, choosing "<a href="http://source.squeak.org/FFI">http://source.squeak.org/FFI</a>". Open this repostiory. In this repository, choose the "FFI-Win32" package. Pick the latest package (currently FFI-Win32-nice.12.mcz) and load it.</div><div><br></div><div>At this point Ron's example should work. This will definitely work in a 5.2 image.</div><div><br></div><div>Now, Ron's example will either run the program will no results, or will error out if it can't run, I believe. Try it out first and see if it works for you.</div><div><br></div><div>If it doesn't, then maybe my exmaple (the is just an extension of what Ron stated) will work:</div><div><br></div><div><div>scanScript := ByteString streamContents: [:bs|</div><div><span style="white-space:pre"> </span>bs nextPutAll: 'my.exe > output.txt'); cr; lf.</div><div><span style="white-space:pre"> </span>bs nextPutAll: 'del '; nextPutAll: (fn := 'Scan', serverName, '.bat').</div><div><span style="white-space:pre"> </span>].</div><div>file := FileStream newFileNamed: fn.</div><div>[file nextPutAll: scanScript] ensure: [file close].</div><div>Win32Shell new shellExecute: fn.
