vb.net upgrade: I just started a new job where I will be either porting a legacy .25
MLOC VB.6 app to VB.Net, or redesigning from scratch and reimplementing.
Frankly, the latter option is probably the one that needs to be done, as
the existing app has evolved over the past 8 years from VB3 and makes
extensive use of the Win32 API (thanks to Dan Appleman!)

I decided to take a stab at automated conversion and started the upgrade
wizard yesterday morning. It ran through the day and long past the time
that I left work. I figured it would be done when I returned this morning.

Unfortunately when I returned this AM, the VB.Net session with the
running wizard had apparently crashed - VS.Net was closed with no
apparent error.

A couple of q's: has anyone seen anything like this before? Does the
process of running the upgrade wizard leave any logs or clues lying
about that might give me some idea as to what is going on?

I talked to the folks at Artinsoft who wrote the wizard for MS, but they
told me that they don't suppport the product, I should talk to MS instead.

TIA!

Hi John.

Thanks for your reply.

To answer your specific questions, there is a log file in the directory
- about 800K worth, but there are no obvious problems indicated therein,
except for the issues encountered in upgrading. And, I'm using VS.Net
2003.

Some additional info. I did some additional poking around not long after
I started this process and discovered that it appeared that the wizard
actually completed its job - I have a converted project with 88 printed
pages of issues (on the order of 5000 individual problems that need to
be solved.)

I also noted that the IDE was behaving strangely (the cursor pulse
between arrow and hourglass as if the IDE was trying to do something)
and trying to open the htmp upgrade report crashed the IDE. I finally
renamed the report in Explorer and the IDE is now stable again.

The upgrade report is something about 1.6 MB in size - I wonder if that
might be the problem?

This app is going to be a monster to migrate. My boss does not want to
rewrite from scratch - I do understand his logic - but he and the guy
who have been working on this for the past 18 years are not trained in
contemporary software engineering techniqes and the code shows it. There
are over 250 separate modules (forms, modules, classes) in a single VB
project. In addition, they have written a custom DLL in Power Basic to
speed up many things that were much slower in earlier versions of
VB/Windows.

If it'll help you troubleshoot the Wizard, I'd be happy to zip up the
log and report file and send it to you. As far as the impact for me,
since I seem to have been upgraded, I'm out of trouble there.

Thanks for any help you can give me!

Bo

Hi Bo,

I'm sorry to hear you ran into problems. I'm guessing since you posted
this a few weeks ago that you may have already found the solution but in
case not there should be a project log file created in the output directory
that might shed some light on the problem.

If you still need assistance can you please tell me which version of VS.Net
you're using?
