This file must be converted with binhex 4.0 lotus

Solutions that demand reading everything into core don't cut it in my book. The first MPEG file that comes along can louse up your whole day. So, there are no size limitations in this module: the data is read on-demand, and filehandles are always an option.

A lot of the byte-level manipulation that has to go on, particularly the CRC computing which involves intensive bit-shifting and masking slows this module down significantly. What is needed perhaps is an optional extension library where the slow pieces can be done more quickly Volunteers, anyone? Even considering that, however, it's slower than I'd like.

No doubt I'll attempt some as time goes on Basically, it works in a similar fashion to stdio's fread :. These are maintained in the object, so parsing two different input streams simultaneously is possible.

Files on the Macintosh consist of two parts, called forks : Data fork The actual data included in the file. The BinHex format squashes that data into transmittable ASCII as follows: The file is output as a byte stream consisting of some basic header information filename, type, creator , then the data fork, then the resource fork.

Expr Input a HEX stream from any open able expression. NoComment If true, the parser should not attempt to skip a leading " This file Skip past the opening comment in the file, which is of the form: This file must be converted with BinHex 4.

Read in the BinHex file header. You must do this first! The leading comment is output, using the requires attribute. Note that done always converts and hands you whatever is left. Someday, the converter may also allow you give it an object that responds to read , or a FileHandle, and it will do all the nasty buffer-filling on its own, serving you stuff line by line: Someday, maybe Feel free to voice your opinions. How to get them The first line said something like "This file must be converted using Binhex 4.

Too late now -- but maybe deleting that initial text line would have let WinZip open it?? Debra, My WinZip would not convert the file either. Warren Linds. Reply to author. Report message as abuse.

I have downloaded a file sent tome with an attachment that says "must be converted from binhex 4. Someone gave me advice to use winzip but that didnt solve the problem either. Any advice on how to view such files? Debra Earle. Charles Rossiter. Warren, WordPerfect 4. Jim Latham. You kind of hinted at it, but I suspect that he needs to install the conversion filter for 4.

I don't believe that it gets installed with a typical install. Community Bot 1 1 1 silver badge. What is your code? What is not working about your code? Stack Overflow might be cool and all, but it doesn't yet have a crystal ball. I tried the base64 decoding as below. As BinHex format has been in practical use in many places, I expect a number of BinHex-encoded resources around the web.

As using the official BinHex software to decode such files requires access to a Mac as far as I understand things, that's not always an option, so being able to decode these things using Java makes sense.

I'm a bit surprised that this question has been closed, and will vote to reopen. Add a comment. Active Oldest Votes. It uses a different alphabet, though: BinHex:! Implementation The following code will decode a BinHex input file and write its data fork to an output file. Secondly, to bundle in a single container both forks composing a Macintosh file. Last but not the least, the author, Yves Lempereur, added a compression function, of the RLE type, to avoid sending repetitive sequences of identical characters.

The suffix used for binhexed files is generally HQX. Please note that this comment line is not mandatory, according to the specs, but that all utilities we already used put this line at the beginning of the file.

The BinHex standard also specifies that the first and last character of the data stream should be a colon :. Most classical binhexed files only have this first comment line, followed by a carriage return and a line feed and only one pair of those.

However, we already saw files where this line was not the first one, but the second one. Our programs were amended to also handle correctly such files. The BinHex standard is one of the working modes with Mime of most Macintosh mail softwares. Those packages code and decode the data stream automatically, and most users never know they are using binhexed files. Things are different when a Macintosh user sends a file to a PC user.

Some mail packages on the PC don't know the BinHex standard and just store the coded file on the hard disk.
