Exception on closing a window.

[libin-3]

Dear All,

 

I am getting an exception while closing a child window using 'X' button of the window.

The whole application is crashing after giving the following messages.

Interestingly, this is only happening when running the application using .net framework and not when running the application using mono.

 

We suspected some 'Dispose()' code in the OnDeleteEvent, but it is happening even if I comment the whole code inside OnDeleteEvent.

 

Message: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." 

 

Source: glib-sharp

 

Stack Trace:

 

   at GLib.Object.PerformQueuedUnrefs()
   at GLib.Timeout.TimeoutProxy.Handler()
   at Gtk.Application.gtk_main()
   at Gtk.Application.Run()
   at LmEdit.LmEdit.Main() in D:\Lm_Edit\src\common\LmEdit.cs:line 49

 

Any help  would be highly appreciated.

 

Many Thanks,

 

Libin

Hi 

I this using mono 2.0? I had a similar problem and upgrading to mono 2.4 fixed the problem.

Hi jensen,

Thanks for the input.

I am using mono 2.0.1

But the problem is only happening when running without mono

 

1. when I am running from visual studio with or without debugging

2. When using the application installed using MSI on windows

 

Using mono the application is working fine.

I have no idea what is really going on here, but it seems like an object
is disposed by your code before Gtk# tries to do that.

Set the environment variable "GTK_SHARP_DEBUG" to some value before you
run your program from the console. You should get a stack trace of the
GLib-Critical then. Post the stack trace to the list or file a bug
report with a small test case.

I got cause of this problem.
Inside the child window (Which I am closing using 'x' button causing the
exception)code I am using 5 events of that window.

  1.WindowStateEvent
            2.ConfigureEvent
            3.FocusInEvent
            4.ResizeChecked
  5.DeleteEvent

And in configure event I am using with [GLib.ConnectBefore] attribute for
calling that event ahead of all.

When I am commenting the focusin event and resizechecked event the code is
running fine.

Is there any problem in using both of this events? Or whether there is any
problem in using these two events in conjunction with the configure event
with Glib.ConnectBefore?

Please throw some light on this.

Many Thanks,

Libin
