Hi misters,

I try use an OCX in my Winforms application with VS 2005.

The OCX is a PDF Viewer (XPdfViewer)

I have several issues about it:

1. I add reference to COM, and VS generate Interop.XpdfViewer.dll

When I call to method of COM, I get this error:

ErrorCode -2147467259

Exception Details: System.Runtime.InteropServices.COMException: Error
HRESULT E_FAIL has been returned from a call to a COM component

One question, how I get a detail description of a COMException ?? Any help
please.


2. I Choose Items in Toolbox and select COM (OCX). The VStudio generate
AxInterop.XpdfViewer.dll.

(which is the difference AxInterop.XpdfViewer.dll and
Interop.XpdfViewer.dll???)

For a Component Control, in design, the control XPdfViewer NOT appears in
toolbox, why ???

For Forms, in design, the control XPdfViewer appears in toolbox
For UserControl, in design, the control XPdfViewer appears in toolbox


Any suggestion about it ? Thanks in advance.
