WMP and SetMute |
|
|
I've tried to use SetMute function from WMP activex control in a dialog based
window but it don't work. All others commands are in GetControls() like here:
CWMPPlayer4 m_ctrlPlayer;
m_ctrlPlayer.GetControls().play();
SetMute is in CWMPSettings.
if I do this:
CWMPSettings settings;
settings.SetMute(TRUE);
or
settings.SetMute(FALSE);
I haven't any result.
I ask: how is possible to use SetMute function?

I don't know a *method* to set that. Are you sure you shouldn't just
set the property directly, as the SDK states :
player.settings.mute=[true | false]
Maybe you're getting confused with the SetMode method ?

I'm talking about c++ programming. I can't do what you say. I need to set as
mute the WMP volume. As I have described above I can't to use the SetMute
function inside CWMPSettings class becouse I see in the VC6 debug window the
message "Warning: attempt to call Invoke with NULL m_lpDispatch!".

OK, sorry. I don't know what true and false enumerate to in C++ :
However the SDK states in the property translation guide :
================================================
"In JScript, the following syntax block is for a read-only property
that contains a String value representing the duration of the current
media item:
player.currentMedia.durationString
The C++ equivalent is an accessor method that returns an HRESULT and
places the durationString value at the location specified by the
pbstrDuration pointer:
HRESULT get_durationString(BSTR* pbstrDuration);
================================================
So I'm guessing it should read as
IWMPSettings put_mute(BOOLEAN);
instead ?

Thank you Neil but in this way you can't help me. I need somebody that knows

Don't you need to do something like this?
CWMPSettings settings = m_ctrlPlayer.GetSettings();
settings.SetMute(TRUE);
Another alternative is to use the regular COM interfaces:
#include "wmpsettings.h"
CComQIPtr<IDispatch> dispatch = m_ctrlPlayer.GetSettings().m_lpDispatch;
if (!dispatch)
return E_NOINTERFACE;
CComQIPtr<IWMPSettings2> settings(dispatch);
if (!settings)
return E_NOINTERFACE;
settings->put_mute(TRUE);
