Untraceable Crash (Project Solution Included)

[Troy Lundin]

I messed up my solution back in July of last year. I did something, no idea what, and it crashes consistently with viewing the designer of certain forms. I recently decided to try and figure it out again and just cannot get anywhere.

So, as a last resort, I come to the VBForums community. Below I provide links to a gif I made of the crash, as well as the solution that causes the crash. The solution to load is: 'GBA\_GBA\GBA.sln'.

After opening the solution, open the designer for the form 'Character.vb' in the project 'ISE Editor (28 July 2014)1'. That should trigger the crash.

The debug method I used is shown in the gif. I open a second instance of VS, attach the first instance to the second, then open the aforementioned 'Character.vb' form. I then step through the code, line by line, until the crash. I have try statements but the crash happens between Sub New() and Try. No idea what's going on.

Thanks for any help provided.

Hopefully you have learned from this and are now using source control, so that you can easily roll back to a previous good state. If not, look into that now.

I don't have time to address the issue right now (dinner on the table going cold) but will get back soon.

I cant look at your solution, but a common thing causing a crash when you don't appear to be stepping though code, especially on New, are variables you have declared that are being given default values.

i.e.

Public Class MyClass

Private MyString As String = GoAndGetString()

Public Sub New()

End Sub

Private Function GoAndGetString() As String
  Throw New Exception("erog")
End Function

End Class

Note, I just typed that ^^ out, but should give you an idea.

@jmcilhinney: Which source control would you recommend?
@Grimfort: There are no values being set at the variable declaration.
