I used the template from the WMP SDK for Visual Studio for a Metadata UI
Plugin. I was able to make a little area with a button I could click and
have the metadata written to a file on the computer. However, I want this to
automatically happen whenever a song plays. Nothing I seem to be able to do
within the CPluginwindow.cpp seems to be able to affect anything outside that
little box that it creates.
So, within my main file, called search.cpp, I left it exactly the same
except that I added the following: (any typoes are irrelevant - I don't have
access to that computer right now, so I'm copying it off a printout. It
compiles, so ignore typeos)
BOOL CSearch::IsPlaying()
{
WMPPlayState state;
if(m_spCore)
{
m_spCore->get_playState(&state);
if(state == wmppsPlaying)
{
USES_CONVERSION;
HRESULT hr;
CComBSTR bstrValue;
CComBSTR bstrName;
CComPtr<IWMPMedia> spMedia;
hr = m_spCore->get_currentMedia(&spMedia);
if(SUCCEEDED(hr) && spMedia)
{
long lCount = 0;
spMedia->get_attributesCount(&lCount);
FILE *fp=0;
fp = _tfopen(_T("my file page and filename"), _T("a+"));
if(fp)
{
_ftprintf(fp, _T("*****\n"))
for(long i = 0; i <= lCount; i++)
{
spMedia->getAttributeName(i, &bstrName);
spMedia->getItemInfo(bstrName, &bstrValue);
_ftprintf(fp, _T("%s : %s \n"), OLE2T(bstrName), OLE2T (bstrValue));
}
_ftprintf(fp, _T("**** \n"));
fclose(fp);
}
}
}
}
return true;
}
This doesn't do anything when I run the plugin. I realize why - nothing is
calling it! How do I get WMP to call this every time a file is played? I
have been trying to figure this out for WEEKS! Any help would be greatly
appreciated!
