Changing the default file extension in a visual studio 2015 project

Question

0.00/5 (No votes)

See more:

When creating my current project using Visual Studio 2015 I incorrectly specified the default file extension to be used (a Document/View project). (i.e. this is the extension that is automatically appended to a file name using the "Save Document" or the type of file filter automatically applied in a "File Open" action.) Other than recreating the project from scratch, how can I change this default extension?

What I have tried:

I have searched the "Properties" for the project, but I cannot find any reference to the (incorrect) file extension that is being applied.

It is stored as resource in the String Table. Look for the ID that is passed to the document template constructor (usually IDR_MAINFRAME).

The string consists of up to seven new line separated substrings. The meaning of the substrings is explained at CDocTemplate:: GetDocString[^].

It also in the *.reg file - it used to register the application as handle of that file extension...

Thank you.
I forgot about the file type registration.

Much appreciated! The string table + *.reg file fixes solved the problem.
