This maybe a LUA bug rather than FH but if I do:

fhSetValueAsText(objFILE, 'C:UsersTestPicturesbag.jpg')

LUA sets the objFILE value to:

C:UsersTestPictures[?]ag.jpg

(where ? is a strange character rendered as a black box with a circle in it)

This can be seen in the debug variables window and is also the value put into the multimedia record in FH.

PS: I have only noticed this since 5.0.0.5. I *believe* it was working OK before but cannot guarantee it.

This isn't a bug - it's a feature of Lua. Within Lua, the backslash character '' has a special role in strings (as it does in other programming languages like C and C++). For example, 'n' means the newline character and 't' means a tab character. If you want to put a backslash into a string, you have to double it up to remove its special meaning. i.e. the line you needed was this:

fhSetValueAsText(objFILE, 'C:\Users\Test\Pictures\bag.jpg')

If you use that, the correct value 'C:UsersTestPicturesbag.jpg' will be inserted.

In case anyone reading this doesn't know what a 'string' is, incidentally, it means text in quotes.

Just to add to this, the escaping of the is only needed if you are entering the string directly in the source code, if you are prompting for a file name or obtaining it from iup.getfile or similar it can be entered as normal.

This is detailed on the Lua Quickstart page in the plugin help.
