FWIW, I've recently seen the reverse problem -- DdeClientTransaction()
says it succeeds, and my (synchronous write) succeeds, but
DdeGetLastError returns DMLERR_INVALIDPARAMETER (all my parameters are
valid, honest!) I've tracked the DMLERR_INVALIDPARAMETER back to
Dynamic Data Studio (which I'm using as the test server -- thanks,
Roger). It looks as though a server can insert something into
DdeGetLastError's memory independent of the function you last called
<insert Twilight Zone theme>. Willying indeed!
