I've been using GridMove for some years. Tried some own and contributed grids. I've settled down with this one, i believe it's the best:

Wow I think this is the /thread post. That's a lot of choices. Thanks for the contribution.

Read over the docs and I'm not seeing how to capture the active window only. Tried a few things (-setfore, -client) and still it's not working.

    "c:\Program Files\MiniCap\minicap.exe" -save "c:\temp\screenshots\capture_$customdate$_$appname$.png" -customdate "$Y$m$d_$H$M$S" -sleep 2 -closeapp -exit -client

I see options for capturing the screen and the whole desktop. Seems that not turning on either of those, it'd default to just the active window. But when I run that command (with or without -client) it never captures, it just doesn't do anything (update: it starts the redbox mode, but that gets hidden by the window).

I did manage to get what I want by using -captureregselect but I'd ideally like to write a bat file that just dumps the current active app to a screenshot after a delay.

Yeah it's -promptsave. That did help, but it's still not working the way I want. Here's the more correct version:

     minicap -save "c:\temp\screenshots\capture_$customdate$_$appname$" -customdate "$Y$m$d_$H$M$S" -sleep 2 -capturescreen -closeapp -exit

Two issues:

First, it's not saving files. If I use -promptsave then it asks me where to save and I just hit OK on that dialog and it works fine. But without the promptsave it won't do anything.
Second, there is a dot after the $customdate$ token, so it does "capture_20110815_092802_cmd..gif".

I'd expect the app to return an error if the filename isn't a valid filename, instead it just fails silently. Silent failures are bad usability.
