The IDAutomation ActiveX barcode controls allow generation of Windows-Enhanced Metafile images and printing from Visual Studio.NET. IDAutomation recommends using .NET Forms Barcode Controls instead of ActiveX if possible.

An image may also be saved the a local hard drive with the following code:
Private Sub cmdSaveToFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSaveToFile.Click AxBarCode1.SaveBarCode("C:\SavedBarCode.wmf") End Sub
Copying the image to the clipboard is only supported with IDAutomation's .NET Forms Controls.
