WPF errors

Hello,

Sorry for posting in English. I'm not very good in french. :(

I'm using C#. and using the
Interop.AcoX0127.dll

When I make Win forms I have no problems...

I'm trying to make a WPF application using Acomba as the "Back-End"

I have 1 button and

one text box

The button will connect to Acomba this will work with no problems but as soon as I click the text box after I click the button I am graced by the following error...

System.ArithmeticException was unhandled

Does Acomba Not like wpf? Is there a work around?

Thanks.
Josh

I did not tried to build a WPF application with Acomba yet, but I would say looking at your stack that the error could be caused by anything else. Nowhere in the stack I can see an Acomba module. Just for test purpose, did you tried to remove all calls to Acomba and run your application again?

I posted this almost a year ago. I moved to an asp.net application. I'm not sure 100% what the problem was. I'm going to try to move my app to a silverlight app and we'll see what happens...

Thanks for responding even though this is an old thread.
