I want to simulate what happens when the user does a File/Open and selects a
particular file. What I expect is: if the file is in the solution, the
projectItem is selected, and the file is opened in the document area. The
problem with the below code is that if the file isn't associated with VS (
e.g. a txt file ), then it doesn't open insde VS. Instead, for example a
.txt file, notepad is launched.
((EnvDTE.DTE)getService(typeof(EnvDTE.DTE))).ExecuteCommand("File.OpenFile",
fileName);

Hi Greg,

Try using something based on this:

EnvDTE::ItemOperationsPtr ptrItemOperations =
m_pDTE->GetItemOperations();
ptrItemOperations->OpenFile( _bstr_t(sPathName),
EnvDTE::vsViewKindTextView);

This is an unmanaged C++ version using smart pointers, but the principles
should be the same in any VS.NET language.

Sorry:

ItemOperations.OpenFile(fileName, EnvDTE.Constants.vsViewKindTextView);

does the same thing. Also trying vsViewKindAny and vsViewKindPrimary for
the constant result in the same behaviour.

Glad to be able to help!

We actually use that code in our Visual Lint add-in to open std.lnt and
options.lnt (PC-Lint configuration files in text format) for editing inside
the IDE, so I was beginning to wonder whether we'd missed something....

Figuring out how to achieve your aims using the extensibility interfaces
seems to be more of an art than a science. A case in point: a little while
ago I posted a query here on how to catch double click events in the Output
Window. Although I didn't get any replies, we eventually realised we could
use some logic in the WindowActivated() event to achieve the same aim.

It's not at all obvious though, and there's so much experimentation and head
scratching in the process!

Good luck with your project.
