[Solved] Thumbnail Control

[pseongho]

I downloaded the trial version and tried to create an sample app with thumbnail control.
I created it in MFC project. When I call Initialize funciton, I can't use GetOcx() since the base class of the ActiveX wrapper class is CWnd and it doesn't have GetOcx() method.

m_pdf.Open( CString( "c:\\test.pdf"), NULL);
m_pages.Initialize( m_pdf.GetIDispatch( FALSE));

I used GetIDispatch instead, but my app crashes. Could help?

Hello

For the MFC wrappers of ActiveX controls the call to make to get the ActiveX interface pointer is not GetOcx() as in C#. It is GetControlUnknown().

So this should be:

Code: Select all

m_pdf.Open( CString( "c:\\test.pdf"), NULL);
m_pages.Initialize( m_pdf.GetUnknown());

Hope that helps?

Maybe this can help someone else..

m_pdf.Open( CString( "c:\\test.pdf"), NULL);

LPUNKNOWN pUnk = m_pdf.GetControlUnknown();
LPDISPATCH pDisp = NULL;
pUnk->QueryInterface(IID_IDispatch, (LPVOID*)&pDisp);
ASSERT( pDisp);

m_pages.Initialize( pDisp);
