« on: December 07, 2015, 00:25:27 am »
I see that you found my latest input on this problem in another thread.  It was a real-time track of my search for a solution with me reporting my progress at each significant point.

Looking forward to the fix.

Thank you for all you do!

Best regards,

Jerry

Bug Reports / Re: [34] Can't Read old CB files with version 0.9.8P

One other minor issue:  inches / millimeters.

If the original is in inches then the corrected file should have the units="Inches" included in that second line.
If the original is in millimeters then the corrected file should not have the units="Inches" included.  Leaving it out causes the design to default to millimeters.

Best regards,

The Country Tractor Welcome found in this forum is fixed by replacing the second line of text in the .cb file with this:

<CADFile xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Version="0.9.8.0" Name="JOHNDEERECLOCK-3" units="Inches">


Then changing Name="JOHNDEERECLOCK-3" to Name="WELCOME".  Just to keep the name correct.

The John Deere Clock is from this forum also.

Best Regards,

Jerry

Being a retired Senior Software Engineer I can help but comment:

1.  The P version does check for the existence of a version object but doesn't report it's non-existence with enough information to make it easy to understand and correct.  Leaving the user with a file that won't load.

2.  The P version does check the version object for proper format and reports an invalid format correctly. i.e. "0".

3.  The P version apparently checks the version object for being a valid version but fails silently when the version is invalid. i.e. version is set as "0.0.0.0".  What are the versions that N is checking for?

Best regards,

Jerry

Okay,

Further investigation finds that the "old" file fails when being loaded by 0.9.8P because it doesn't have a version object defined.

Okay,
The solution to this problem is simpler than we would have imagined.

Replace the second line of text in the failing file with the second line of text in the Save as... file.

i.e.
Replace this:
<CADFile xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Name="Unititled" units="Inches">

with this:
<CADFile xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Version="0.9.8.0" Name="JOHNDEERECLOCK-3" units="Inches">

The file then loads with no errors.

Have a nice day!

Best regards,

Jerry

I attached two files and it appears that only one got uploaded.
This one is the original.

The changes are extensive.  The easiest way to see the changes is to open and Save as... with 0.9.8N then compare the original to the Save as.
Attached are the original and the Save as...

I find that if I open the old files in 0.9.8N and then Save as: they are readable in 0.9.8P.  The Save as makes significant changes in the machine ops section of the .cb file.

CamBam help (General usage) / Object reference not set to an instance of an object - error.
« on: December 03, 2015, 04:37:09 am »
Please excuse my posting the same subject again.  The previous posts appear to be somewhat different than my symptoms and they are several months old.

After I updated CamBam to 9.8P I discovered that I experience the above subject error on occasion.  It is related to .cb files that I have downloaded from this forum.  In particular the JOHNDEERECLOCK.cb file and the Nema 23 Mount v1.2.cb files.  They fail consistently and never load because of the subject error.

Other .cb files on this forum consistently load just fine.

A screen shot of the failure message is attached.  Not that it is needed but I am sending it anyway.

I am running Windows 7 Ultimate which is continually updated as patches are released.
16 GB RAM
Quad-core 3.4Ghz (8 processors)
Several Tbytes of rotating media
Dual 24in HD monitors.

I find that if I uninstall 9.8P and install 9.8N the problem goes away.
Upgrading 9.8N to 9.8P caused the failure to return.

You can reproduce the problem by downloading either of the above referenced files and either allowing explorer to automatically run CamBam and load the file or save the file and use Cambam to load the offending file.

Either way produces the same failure mode.

I have many files that I have created over the years with several older versions of CamBam and none of them cause CamBam to exhibit the above symptoms.

Best regards,
Jerry Ross
