Hi,

 after I compiled a project as AnyCPU in Visual Studio 2010 (C#) and started to debug it on a 64 bit system I got the following stacktrace

 System.OverflowException was unhandled
  Message=The arithmetic operation caused an overflow
  Source=Xceed.SmartUI
  StackTrace:
       bei Xceed.SmartUI.Win32.SingletonKeyboardHook.Hook(Int32 code, IntPtr wparam, IntPtr lparam)
       bei Xceed.SmartUI.Win32.Win32Hook.IntPtrHookProc(Int32 code, IntPtr wparam, IntPtr lparam)
  InnerException:

 at first I thought it was related to a bug in my sourcecode but soon after this one, I got the exact same error on a complete different project, too.

It's always coming from a ShowDialog() method and it happens as soon as the user tries to enter a text into a textfield. In one case it happens on a WPF form, in the second case it happens on a System.Windows.Forms.FolderBrowserDialog when I try to add a new folder. (I click the "Add new folder" button and as soon as I try to give the new directory a name the OverflowException occurs).

Operating system is Windows 7, 64 bit (as mentioned before). If I set the compilation target platform to x86 everything works.

 So my questions are: Is Xceed.SmartUI x64 compatible by default (I ask that because of the win32 namespacepart)? If yes: what is going on there?!

If not, is there a x64 compatible dll or will there be a x64 compatible dll?

Hi,

I encounter the same problem:

System.OverflowException: Arithmetic operation resulted in an overflow.
     at Xceed.SmartUI.Win32.SingletonKeyboardHook.Hook(Int32 code, IntPtr wparam, IntPtr lparam)
     at Xceed.SmartUI.Win32.Win32Hook.IntPtrHookProc(Int32 code, IntPtr wparam, IntPtr lparam)

Thanks,

Marie

Hi, 

Can you send us a basic sample application that demonstrates this issue so that we investigate this in more detail?  

 You can send it to support@xceed.com

Please include a reference to this forum post in your email.  

Hi Curtis, 

As in my last reply, we still can't reproduce the problem.
If you are able to reproduce it in a sample application, you can send it to support@xceed.com so that we look further into this.  

Since the time I opened this thread, I found two more applications with the same problem.

In all cases, the project in which the error occurs has no reference to Xceed components, and in two cases even the referenced projects have no Xceed components (only some of the projects that exist in the same solution have Xceed components).

And why should an EventHandler from Xceed listen to WPF/WindowsForms TextBoxes (which apparently happens)? Or how? Let alone without having a reference to the project and the properties of the TextBoxes are privat.

 oh and I don't seem to be able to reproduce the problem. I tried different approaches but it seems I miss something.

 The Version of my SmartUI is 3.4.7264.16200

*edit

I just saw that it's not related to ShowDialog(), a regular Show() results in the same error.

Hi Dirk,

Unfortunately, without a sample application, we will not be able to investigate into the matter. If at some point you are able to reproduce this behavior in a sample application, you can send it to us by email at support@xceed.com

Hi Dirk,

I'm also facing the same problem. Did you get any solution for that. Could you please post it.

Thanks.
