Error in OpenFileDialog

Hi,

I try to use the winforms.OpenFileDialog. In a previous version of 
mono, it runs correctly, but now (since mono 1.1.10) a mono thorw 
an error. 

I only initialize the OpenFileDialog:
this.openFileDialog1 = new System.Windows.Forms.OpenFileDialog();

I think, this is a bug in the mono version 1.1.13.
Have anyone a workaround for the problem ?

I don't have this problem here:
--------------------------------------------
$ booish
Welcome to booish, an interpreter for the boo programming language.

Running boo 0.7.5.2013.

The following builtin functions are available:
    dir(Type): lists the members of a type
    help(Type): prints detailed information about a type
    load(string): evals an external boo file
    globals(): returns the names of all variables known to the
interpreter

Enter boo code in the prompt below.
>>> import System.Windows.Forms from "System.Windows.Forms"
>>> dialog = OpenFileDialog()

Error Running WinForms App -- Revisited

As some of you know a little while ago I was having trouble compiling
a very very basic windows form app and getting it to run on mono, once
of the suggestions was to ensure that my version of mono and
libgdiplus are the same and to update them. Well it has taken me a
long time but I have update them both to 1.1.13 (libgdiplus) and
1.1.13.1 for mono.

I tried the same app and got exactly the same error as before:

Re: Error Running WinForms App -- Revisited

Hi,

As I see in your paste you're running KDE. I've got Gnome and your
sample works right! The only problem can reside in the Desktop dependent
code. Then you can try it in "failsafe" or "gnome", if you have this
last installed, and report the results.

Regards,

    Pedro

Re: Error Running WinForms App -- Revisited

Freddie,

IRC channel is #mono-winforms, on irc.gimp.net.

Would love to resolve this, before we cut 1.1.13.3

Cheers,
 Peter

Re: Error Running WinForms App -- Revisited

Just a small update for all of you who are watching this topic/ 
thread. With help from the very friendly people on irc.gimp.net #mono- 
winforms we managed to find out that the cause of this problem was  
because of the -fomit-frame-pointer CFLAG. which for some reason was  
causing the application to seg fault.

By Compiling the library without the -fomit-frame-pointer cflag we  
were able to solve the problem. The proposed solution is to patch the  
configure/make file script to check if the -fomit-frame-pointer is  
turned on and if so disable it.

TrayIcon

Hi,

I want to test TrayIcon classes and when I run the samples (in winforms
module from SVN) I can see a new window with the Icon... I'm using Gnome
and I thought that the icon should be in gnome's tray (or freedesktop's
tray). Can I get it there in any way?

Regards,

    Pedro
