COM/COM+ programming in .NET 4.0

Hello group,

Is COM/COM+ still alive in windows development? I'm looking for a solution and interface to use Visio design features in a customer application. Is it possible?

my plan is to embed Visio designing features in my application. How feasible is this?


Any help is appreciated.

Regards,
ak

The old OLE Control is gone and has not been provided in the Visual Basic PowerPacks, a package that Microsoft issued to provide .NET programmers with some of the controls that disappeared, such as the PrintForm and DataRepeater.

So you will not be able to integrate Visio with its menus and its complete functionnality.

However, you might try to reference Visio and integrate some of its components (there was a Chart or Page component if my memory is good) as controls inside of .NET forms. I do not have Visio anymore, so I cannot check. Integrating COM controls sometimes work in .NET, sometimes it does not. It depends on the control.

Thanks, yet I'm wondering why they have a project types for Office 2007 and 2010 in VS 2010.
My goal is not to customize Visio's menu but instead being able to show a canvas in my custom application where user can use a set of design tools and create a harness or design and save it as file format available to Visio.

I will appreciate it if an expert could comment on that.
