UNC path for My Documents in FileBrowser

Hi Johannes,

 

The VW parcel is attached. Save and restart the image after loading the attached parcel.Let me know if it helps. If it does then I encourage you to report the problem to Cincom and share the code with them.

 

I have an internal blog post that should describe the problems and fixes in more detail. If needed then I'll share that too.

Johannes,

 

I've reported UNC inconsistencies for VW 7.5. Cincom made changes in 7.7 that appears intended to address part of the problem. Here are the code comments for my fix of problems that remained:

 

        VW uses FATFilename conventions by default when it can't figure out the

        correct convention. Defaulting to FATFilename has side effects and one

        is that filenames with drive letters are treated different than UNC filenames.

 

                Filename named: 't:\ALongFilenameThatDoesNotExist'

                        a NTFSFilename('t:\ALongFilenameThatDoesNotExist')

 

                Filename named: '\\someplace.com\goodname\ALongFilenameThatDoesNotExist'

                        a NTFSFilename('\\someplace.com\goodname\ALongFilenameThatDoesNotExist')

 

        Looks good so far, but this is what happened when the drive/server part of the name doesn't exist:

 

                Filename named: 'k:\ALongFilenameThatDoesNotExist'

                        a FATFilename('k:\ALongFilenameThatDoesNotExist')

 

                Filename named: '\\someplace.com\BadName\ALongFilenameThatDoesNotExist'

                        a FATFilename('\\someplace.com\badname\alongfil')

 

        Cincom gave a way to set a DefaultClass; however, that way is broken.

        This code fixes the problem so that when Filename.DefaultClass is

        changed from PCFilename to NTFSFilename then it will consistently use

        NTFSFilename as the default. One example is given above but there were

        several methods afflicted with bugs of this nature. You'll see by reviewing this

        code that some of the identification bugs even originate in VW primitives.

 

        The problem had been reported to Cincom and was discussed in VWNC

        forum posts on topic 'UHE saving large image to network drive' in August 2008.

        This code fixes VW 7.5 (and 7.6). I see that Cincom made some changes

        in this area of the code for VW 7.7 and 7.7.1; however, those changes

        don't appear to be intended to fix these problems.

 

FAT was a good default ten years ago, but VW probably isn't even supported on FAT-based Windows versions anymore. In a world of UNC paths, NTFS is a better default than FAT. I'll send you my VW 7.5 fixes in a separate email. Hopefully it will be compatible with the VW release you use. If it fixes the problem then please follow up with Cincom so that they can fix the problem in a future release.

Hi,

 

why does the FileBrowser not show the UNC path to My Documents (VWNC 7.8.1, Windows XP or 2000) in the directory tree?
