I have been trying to figure out ways of remotely initializing macros
on my computer. There are remotes that are made for that purpose but
they are too bulky and have far more buttons than I need. I need a
very compact remote with no more than 10 programmable buttons. At
this point I will probably need to use either WinLIRC or Girder to
interface with the type of remote I am needing. Which of these two
programs would be better and would they be compatible with this remote
and IR receiver:

Both of those are RF not IR but Girder should be able to handle the MR26A
serial output.

If both of those devices are RF does that mean they are probably
compatible with each other? Also, how complicated are the codes or
whatever you want to call it that are transmitted by RF? I would
like to write a program in Visual Basic that could take the input from
the serial port to execute different macros.

Yes, they are compatible.

The MR26A outputs a 2 byte header, 2 data bytes and a 1 byte footer. The
details are given here...

In hexadecimal, it's always <d5><aa><data><data><ad>.

One thing I missed was that you want "programmable" buttons on the remote.
The KR22A allows you to assign an X-10 address (from a set of 256) to the
first set of buttons. The next 3 sets automatically follow in sequence and
the last set (Dim/Bright) send codes that depend on which address was
assined to the first pair. While I suspect it will do what you want, the
button "progammability" is extremely limited.
