Error on first run after upgrade from 0.1.5 to 0.1.6 #77

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Running 0.1.5 release
2. Install 0.1.6 beta from setup
3. Launch Witty (or use run after setup option)

What is the expected output? What do you see instead?
Expected program to run. Instead, got "Witty has encountered an error and 
will now close.

Debugged and got the following exception. Believe issue is due to 
upgrading settings - can we trap or prevent this exception?

System.Configuration.ConfigurationErrorsException was unhandled

Viewed user.config file listed in exception - it was full of null characters. I 
think we should detect corrupted config and wipe it out.

I had an 0.1.2 and an 0.1.5 config after running the install (when I got the 
error). 
I deleted the 0.1.5 folder after verifying that the config file was full of 
null 
characters. After that, I was able to run the program and a new 0.1.6 folder 
was 
created with readable settings.

Thanks for finding and reporting this. Good thing we're still just a beta ;-).

Is this still an issue?

Yes. I have encountered this issue (corrupted user.config) on two different
installations of 0.1.7 Beta 1 (one on Vista Ultimate x64 and one on Vista 
Enteprise
x86).  Note that I have not had any version other than 0.1.7 Beta 1 installed on
either machine.

Update to my last comment (comment 5):  After additional forensics, I am 
confident 
in stating that my user.config became corrupted after an OS crash. On the x64 
box, 
the crash was an unexpected shutdown and on the x86 box it was a BSOD.

This is for an old version, not seeing it anymore

Was able to reproduce. Here's some code to detect and remove a corrupted 
user.config: http://www.codeproject.com/KB/dotnet/CorruptUserConfig.aspx

I've checked in the fix - will test once it's released in the ClickOnce version
