hi.. I get an error like this "Mmsystem295 A parameter or value was
specified twice. Specify it only once." when I try to save my wav file
in mcisendstring. How do I fix this? =) it seems whenever i save my
file to, let's say C:\my documents\wavfile.wav.. this error pops up..
it only works when the path is C:\.. actually, it works for all paths
without extensions like my documents or program files blah blah..
please, anyone? who can help me out? thank you.. =)
