HTML & Text message parts #82

Hi, I've been experimenting with this tool and comparing it to the regular tnef tool on linux. I noticed that the regular tnef tool is able to extract the HTML and TEXT parts of a winmail.dat message (along with RTF if it's there). Is it possible to do the same with this lib?

Yeraze commented 4 years ago

I'm sure it can... Can you provide a sample file for testing?

amit777 commented 4 years ago

Sure, I'm going to do a couple more tests and compile the results and send them to you. Is it ok if I email you some of the test files since they have some semi-private data in them?

Yeraze commented 4 years ago

Sure, that's fine.

Actually, I just noticed ytnefprint does seem to find the field and the data in that field looks correct:

 #1: Type: [ BINARY  ]  Code: [PR_BODY_HTML]
    Size: 487    Value: [<html>..<head>..<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">..<style type="text/css" style="display:none;"> P {margin-top:0;margin-bottom:0;} </style>..</head>..<body dir="ltr">..<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">..<span style="font-family: Calibri, Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255); display: inline !important">[[#]]</span><br>..</div>..</body>..</html>..]

So, I guess my next question is does the ytnef binary allow exporting that as message.html or something similar?

Ahh, I see in the ytnef/main.c the saveRTF flag.. looks like there needs to be another flag for the HTML body. I'm going to continue playing around with this. If I find any TNEF's that don't parse correctly, will send it over to you. I feel like I found one that was causing a seg fault yesterday..

I was working on creating a pull request for a couple enhancements. But I was hoping you could clarify this part of the lib/ytnef.h code:

#define attAttachData               ATT( atpByte,       0x800F) /* PR_ATTACH_DATA_xxx */
#define attAttachTitle              ATT( atpString,     0x8010) /* PR_ATTACH_FILENAME */
#define attAttachMetaFile           ATT( atpByte,       0x8011) /* PR_ATTACH_RENDERING */

Where do the 0x800F, 0x8010 and 0x8011 come from? Are they defined in some standard somewhere?

Not really, TNEF (afaik) is something Microsoft made up.. You'll find lots of references to it in the Public Microsoft documentation like this : https://docs.microsoft.com/en-us/office/client-developer/outlook/mapi/pidtagmessageflags-canonical-property

I created a pull request for the HTML body export as well as some additional header defs. https://github.com/Yeraze/ytnef/pull/83

Hopefully it fits your desired coding style! Thanks again for creating this awesome lib.
