BC3 reused instance

[chrisjj]

I need a command for a batch file to show a text compare of two files, but not open a new tab. E.g. launch BC3 or reuse that tab if already launched.

Any ideas?

(Ideal would be launch/refresh a named instance.)

Thanks.

Options....

believe the way to do this is to either use the bcomp.exe command that will launch and wait for exit on a single version or use bcompare.exe and /solo switch.

[chrisjj]

Neither does, sadly. In particular /solo causes rather than avoids a new instance.

We don't provide any way to do that. Programmatically you might be able to fake it using WM_DROPFILES, but that's about it.

Incidentally, I've been wondering what kind of things people would want exposed if we added a COM API or a more complete scripting language. No promises, but if you're doing something that would benefit from from something like that I'd like to hear it.

[chrisjj]

OK, thanks.

What I'd want here simply e.g.

bcompare.exe -name "myinstancename" "filea.txt" "fileb.txt"
