exe genereted by ipyc says "the calling thread must be sta because many ui components require"

[retsyo]

I used the following code with latest ironpython2 and ironpython3 release.
no matter IronPython.2.7.12\net45\ipy.exe gui_wpf.py or IronPython.3.4.0-alpha1\net46\ipy.exe gui_wpf.py can run without problem.

Then I use ipyc to create exe file with

ipyc.exe /embed  /target:exe gui_wpf.py

I copy gui_wpf.exe, form.xaml, IronPython.2.7.12\lib to IronPython.2.7.12\net45\
or
copy gui_wpf.exe, form.xaml, IronPython.3.4.0-alpha1\lib to IronPython.3.4.0-alpha1\net46\.

However when I run gui_wpf.exe in the dos prompt, I get

gui_wpf.exe
Error occurred: the calling thread must be sta because many ui components require

how to fix it? Thanks

the following code is actually copied from https://stackoverflow.com/questions/47953638/button-click-event-on-ironpython-wpf

# gui_wpf.py

import clr
import wpf

from System.Windows import Application, Window

class MyWindow(Window):
    def __init__(self):
        self.ui = wpf.LoadComponent(self, 'form.xaml')

    def Button_Click(self, sender, e):
        print('Button has clicked')

if __name__ == '__main__':
    Application().Run(MyWindow())

and form.xaml is

<Window 
       xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
       xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
       Title="WpfApplication1" Height="300" Width="300"> 
       <Grid>
        <Button x:Name="BUTTON" Content="Button" HorizontalAlignment="Left" Margin="101,82,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click" Background="#FFFF1616"/>
    </Grid>
</Window>

You probably need to use /target:winexe for a WPF application:

ipyc.exe /embed  /target:winexe gui_wpf.py

winexe works. Thanks

but for the original code, the event prints text in dos windows. If GUI+console window are desired, how can we modify the code to let both exe and py work?

Hmm, I'm not seeing any command-line arguments that would enable this. I guess ipyc would need to be modified to add the STAThread attirbute to the entry point.
