RE: WPF feasibility check

[Jake Ginnivan]

Just make sure you add 

If (System.Windows.Application.Current == null)
{
New System.Windows.Application{ShutdownMode = ShutdownMode.Explicit};
}

Without a current application singleton then WPF windows will not work. Also, 
if you do not specify shutdown mode then your app will crash the next time a 
WPF window is opened. :)

Folks (anyone here?), I just want to run an idea past you to make sure it's 
feasible before I start any coding.

We have a large VB6 app that tracks manufacturing jobs of various types, now 
including glass cutting. The app needs to show a picture preview of a glass 
sheet with artistically cut corners of different shapes. Doing this in VB6 
would require tedious and delicate drawing. I suggested that we write a COM 
visible .NET library that would use WPF to draw the picture and pop it up in a 
Form.

I'm sure the COM interop will work and the form will open, as I've seen this 
done before. I'm also sure I can draw the glass sheet beautifully in WPF and it 
could be zoomed and panned (a 3D rotating version would be even more 
eye-popping, but we'll stick to 2D for now). I would have to convert the actual 
edge designs into path geometries, which might require graph paper and pencil 
and a UI tool to compose the required effect, but you would only do that once 
for each corner type and stash it in a library for reuse.

I'm keen to feedback before I make a proof of concept.

Cheers,
Greg

RE: [OT] Australian ALM Conference in April?

[Michael O'Dea-Jones]

Hi Shaun,

The reason I am so interested in the Australian ALM conference is the 
opportunity to see Sam Guckenheimer and Ivar Jacobson who are two luminaries of 
the industry present at the keynote.  I am especially keen to hear what Sam 
Guckenheimer has to say about the future of the Microsoft development products.

I think the real value for this event is that the event is focused on 
Application Lifecycle Management and it will provide me with the opportunity to 
see how Visual Studio 2010 will help with marrying business management to 
development.  I think that ALM is going to become increasingly important as a 
developer and I want to get ahead of the curve.

But the real reason I have registered is to try and win the motorised esky they 
are giving away :)

Of course this requires that all passwords are different and are of 
reasonable complexity.  For half the table to be filled with easily 
guessed passwords like 'password' will defeat any security measure. 
It also means that a user who forgets their password must be allowed 
to create a new one (or have one generated for them) as the old one 
cannot (in theory) be derived from the hash.


Passwords should be one way.  Unless it is data that needs to be 
presented back to the user.  I recently reviewed a system that used a 
text representation of a user's SID as the 256 bit key to protect data 
that did need to be decrypted.  Sounds good in theory, except that the 
first 32 chars (256 bits) of said string are identical for a given 
domain. DOH!


One can easily Google for common raw MD5 hashes.

If you simply add the length of the typed password to the string to be 
hashed, you at least remove the rainbow attack - which is as good as 
'unhashing'.  I'd look to using the username or primary key of the 
user to further differentiate - this will ensure no two hashes of the 
same password match.

HTH.

Thanks for the link.

I had found this previously but while it contained some links to VB I 
needed VBA so the one for VBScript was probably the closest but that 
link was broken.
