Hello.
I have VCExpress and I've found switch "/Edit":
/Edit Opens the specified files in a running instance of this
application. If there are no running instances, it will
start a new instance with a simplified window layout.
But it doesn't work. If I open file from cmd.exe each file will open a new instance. How to use it

How to open file in a running instance?

For example assume that we have running cmd.exe and execute two commands:
VCExpress myfile1.cpp /Edit starts a new instance of IDE.
VCExpress myfile2.cpp /Edit has to open the file in the same instance of IDE as a new tab, but it doesn't. It starts a new instance again.

Silly question, they are two existing files aren't they This works with files that exist, but it fails for non-existant files.
If they both exist, then maybe its a problem with VCExpress.exe, since i tried it with DevEnv.
