[Mono-winforms-list] OpenFileDialog throwing ArgumentNullException

[Trimble, Nathan G]

I realize some people on this list may know the status of various
controls at any given moment, but I imagine there are also some lurkers
on the list who may just be trying to learn a little bit about mono.
I'm pretty decent with C# but not real knowledgeable with mono.  If you
could post a little code along with your questions I might be able to
try running it too.  Just a thought.

Sincerely,


Nate Trimble

Can anyone tell me, is this me doing something wrong or is it a current
bug in the code?

(Assuming I am doing the build properly) mono is the current version
updated 10 minutes ago.

Test program simply declares an OpenFileDialog

Program throws:

Unhandled Exception: System.ArgumentNullException: Cannot add null image
Parameter name: value in <0x00104>
System.Windows.Forms.ImageList+ImageCollection:Add
(System.Drawing.Image value)
in <0x001a6> System.Windows.Forms.MWFFileView:.ctor () in (wrapper
remoting-invoke-with-check) System.Windows.Forms.MWFFileView:.ctor
()
in <0x00236> System.Windows.Forms.FileDialog+FileDialogPanel:.ctor

remoting-invoke-with-check) FileDialogPanel:.ctor
