Need help with this code

[Sophie]

What I'm trying to accomplish is to find the selected Item and make sure it's a file not a directory. And if it's a file I get control of the Multimedia control to paly the wave file selected.

What am I doing wrong? If you require more info let me know

Thank you in advance

void CVRSessionView::OnItemchanged(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
CFrameWnd* pFrame= GetParentFrame();
if( pFrame != NULL && pFrame->IsKindOf(RUNTIME_CLASS(CMainFrame))) {
CListCtrl &ctlList = GetListCtrl();
CObject *pObject= (CObject *) ctlList.GetItemData( pNMListView->iItem); //ASSERT ERROR HERE
if(pObject->IsKindOf(RUNTIME_CLASS(CFileInfo))){
Cmci mci; //Multimedia control
mci.SetDeviceType("WaveAudio");
//mci.SetFileName(fileToPlay);
mci.SetCommand("open");
}

}

class CFileInfo ublic CObject
{
public:
void SetFileInfo(File &fileInfo);
File GetFileInfo();
CFileInfo();
virtual ~CFileInfo();
DECLARE_DYNAMIC (CFileInfo);

private:
File m_fileInfo;
};

CFileInfo::CFileInfo()
{

}

CFileInfo::~CFileInfo()
{

}

File CFileInfo::GetFileInfo()
{
return m_fileInfo;
}

void CFileInfo::SetFileInfo(File &fileInfo)
{
m_fileInfo = fileInfo;
}



*pResult = 0;
}

What is it that is not working?

Look for if(list.size() == 1)

I need to get the multimedia control i've created in the CMainFrame::OnCreate
The code for the multimedia start with "#define SNAP_WIDTH 389"

How do I go from the view to the mainframe?

Thanks in advance
