If I run the C++ unmanaged basic editor sample (bscedt), I get a document
window with just a rich edit control. However, when I run the managed C#
Basic Editor sample, I get the left margin with bookmarks enabled in addition
to the edit control.

Why is the margin visible in the managed sample, but no the unmanaged? Thanks.

Hi Greg,

I don't see bookmarks supported in either of these samples. Neither hosts
the core VS editor. They are both pretty different implementation wise. The
C++ BscEdt sample actually implements the editor as an activex control.
Whereas the C# sample actually implements a UserControl derived object that
hosts a simple textbox control.

Both of these are legitimate samples, but neither actually illustrates how
to host the core VS editor. To do that you need to create an instance of
the COM creatable VsCodeWindow object, and wire it to a COM creatable
VsTextBuffer. You can to this in both VC++ and C#, but in the C# scenario
you'll have to parent the HWND of the VsCodeWindow directly to your editor
pane by PInvoking the SetParent API in USER32.DLL.

I'm interested in this, too. However, I can't find any references to
VsTextBuffer or VsCodeWindow in the VS 2005 documentation. Where can one
find information about them?

Basically, I'm wanting to create an add-in that will create a simple,
blank document without any dialog intervention. This would be identical
to the way VC++ 6.0 editor's "New Text File" toolbar button operates.
Would using these interfaces (VsTextBuffer and VsCodeWindow) be the way to
do that? If not, is there a method somewhere that just opens a new,
blank, no questions asked, text window.

Thanks,
Brian

Hi Brian,

Those components are actually documented in the Visual Studio SDK, and are
typically utilized when building a new editor to support a new language or
sourcefile type. You can download the Visual Studio SDK from:
https://affiliate.vsipmembers.com/.

If you're just looking to create a toolbar button that will create a new
textfile, you can do this via a macro or an addin by way of the
DTE.ItemOperations.NewFile function. Specifically:

DTE.ItemOperations.NewFile("General\Text File")
