I'm trying to solve a bit of a mystery with MCI (Multimedia) ActiveX
control.
Vb.hlp is not of great help when syntax is considered - they assume too
many things are known by default. I'm trying to implement a sound
recorder on a form - nothing too complicated. It should record a
message, store it into a .wav file, copy it to a memo field in some
table, and go wait for the next message.
I can't get the bloody thing initialized properly. It says I should
issue Thisform.Olecontrol1.command with a parameter of "Open", and set
Thisform.Olecontrol1.FileName to "something.wav"; since .wav will be
recognized, I don't have to fill Thisform.Olecontrol1.object.DeviceType
to "WaveAudio". Then it says I'd issue the Thisform.Olecontrol1.command
from form.load (I've put it into .init, since the control probably
doesn't exist at .load time), and it is supposed to return the DeviceID,
which should (automaGically?) be stored into
Thisform.Olecontrol1.object.DeviceID (must be automatic, because it's
read_only).
I've tried
Thisform.Olecontrol1.object.command="Open"
Thisform.Olecontrol1.object.command="Open WaveAudio"
....and several other combinations, but nevertheless can't get any other
DeviceID except 0 and I get error 257: "MMSYSTEM257 Invalid MCI device
ID. Use the ID returned when opening the MCI device.", puts the device
into "mciModeOpen 524 Device not open." mode and generally drives me
nuts. Cann't find the "ID returned when opening" anywhere; besides, I've
tried to set it to any number and it remains so. The devicetype remains
""; if I pre-set it in the PEM window, it remains as pre-set.
How do I get this DeviceID, or am I opening it wrong way? Anyone?
TIA, nDragan
