Error inserting .NET System.Windows.Forms.Form

[miguelc]

I'm a newbie to .NET. I'm trying to insert a System.Windows.Forms.Form into a .NET container on a Front Panel, but get an error: "Error Inserting ActiveX or .NET object: Exception occurred in System.Windows.Forms: Top-level Windows Forms control cannot be exposed as an ActiveX control"

Can someone explain this? I have a .NET program whos main window is a System.Windows.Forms.Form, so I was hoping to embed it into LabVIEW and use it inconjunction with LabVIEW.

Using LV 8.5, Windows XP

Hi miguelc,

This error appears to be generated by .NET/ActiveX rather than by LabVIEW itself.  I found an external site unrelated to LabVIEW coding where a user had encountered the same error.

If you are trying to use a .NET container, perhaps you should try an ActiveX container instead.  Also, if you are able to succesfully call it in another programming language, if you could post that code here we may be able to help you figure out exactly how to translate that to LabVIEW code.

Hi miguelc,

Windows Forms are not .NET controls and therefore you cannot insert them into a .NET Container whose purpose is to host WinForm controls.  Anything you can drop onto a Windows Form in Visual Studio, you should be able to insert into LabVIEW via the .NET Container.

Best Regards,
