Troubleshooting vb.net project in mono

[JDean]

Hello Everyone,

  I've been developing small educational applications in vb.net (using studios 2003) and I just started trying to port them to mac and linux, so I'm pretty new to using mono.  I have a very basic winform application that I'm trying to run with mono 2.4; essentially a windows form with a button and a text box, when the button's clicked, the textbox says 'hello world'.  When running the .exe in mono, it crashes with the following error log:


Unhandled Exception: System.ArgumentException: GCHandle value cannot be zero
  at System.Runtime.InteropServices.GCHandle.op_Explicit (IntPtr value) [0x00000]
  at System.Windows.Forms.XplatUIWin32.GetMessage (System.Windows.Forms.MSG& msg, IntPtr hWnd, Int32 wFilterMin, Int32 wFilterMax, Boolean blocking) [0x00000]
  at System.Windows.Forms.XplatUIWin32.GetMessage (System.Object queue_id, System.Windows.Forms.MSG& msg, IntPtr hWnd, Int32 wFilterMin, Int32 wFilterMax) [0x00000]
  at System.Windows.Forms.XplatUI.GetMessage (System.Object queue_id, System.Windows.Forms.MSG& msg, IntPtr hWnd, Int32 wFilterMin, Int32 wFilterMax) [0x00000]
  at System.Windows.Forms.Application.RunLoop (Boolean Modal, System.Windows.Forms.ApplicationContext context) [0x00000]
  at System.Windows.Forms.Application.Run (System.Windows.Forms.ApplicationContext context) [0x00000]
  at System.Windows.Forms.Application.Run (System.Windows.Forms.Form mainForm) [0x00000]
  at Helloworld.Form1.Main () [0x00000]


Again I'm fairly new to using mono, so any ideas on fixing these issues would be appreciated.  Please let me know if anyone would like to see the vb.net code.

Hi,

This sounds like a mono/winforms bug, you can either file a bug report
(bugzilla.novell.com, Mono/Class Libraries/Winforms) or send a mail to the
mono-winforms-list.
