After looking at the replies years later I found my 'Add Existing Items' (or CTL-D) in the project menu. It was not found in the Solution Explorer window in Visual Basic Express.
Also If your intention is to replace a blank form with this as your start-up. (As was my case through a project page mishap.) Once you perform the copy then use the solution explorer to visit (double left click) the My Project page (or whatever you
have named it.) And drop-down the 'Startup Form:' to select you form you have copied in.
Once you tested your start-up in a debug run you might feel safe to delete the blank form from Solution Explorer. (debug saves your project temporally so run it again or perform a save all from the file menu to make sure the blank form is gone for good.
The Debugger grumbled once still looking for Form1 so with a find (Ctl-F) I located those by searching all of My Project and found 2 which I changed to my new form name. Seems awkward but did save me time.
At the risk of over answering I would like to add I have Moved all (with Ctl-A) or some (Ctl-LeftClick) then copy (Ctl-C) to the clipboard in one open project CLOSE THE PROJECT and pasted them into a
form in another project I OPENED (Not using the Clipboard between of course) . This will bring across the objects and designer properties
and if your clever you can bring the code for those object's handlers in a similar manner. I have merged functionality of different forms in and out of project this way.
(Just wait a few years for the best answer, and I just violated my best rule of no long answers on the web.)
