I think I have the solution.
You need to override the OnCreateClient call on your version of wxMDIParentFrame. You then have to override wxMDIClientWindow that has its own OnEraseBackground method. This will get called.

Sorry Jim,
That doesn't work either.

How can I paint a rectangle if i can't get the erase event to fire?

setBackground doesn't do anything that is why i was trying to override the erase event.

I am trying to change the background color of the parent frame by iverriding the EVT_ERASE_BACKGROUND event but it never gets triggered. Any ideas why? I am using wx 2.8.10 on Win7. BEGIN_EVENT_TABLE(MyFrame, wxMDIParentFrame) EVT_ERASE_BACKGROUND(MyFrame::OnEraseBackground) END_EVENT_TABLE() ... vo...

Windows Explorer is using some other way to launch the app when the doc is doubleclicked. Anyone know how?

What are the new values for CLSID_Pdf and DIID__DPdf?

The Acrobat Reader installers is what I meant.

Here is the latest.
I was able to download the installers for 6.01 and 7.09. Using the exact same wx code version 6.01 works fine. 7.09 and 8 both get the same error. E_NOINTERFACE returned fro the CoCreateInstance call.

Anybody been able to get this working on the later version?

I am on WinXP and have Acrobat Reader 8. If I go into IE7 Manage Addons it lists Adobe PDF Reader as Enabled. Anything else I can check?

It returns E_NOINTERFACE which I assume means I need the full version of Acrobat. Thats lame. Anybody know of another way?

Just Reader. Is Acrobat required? If so is there another way to get a preview of a PDF?

I am using the code in the help docs trying to view a pdf. The code hits the CreateControl method in wxPDFMediaBackend so I know it is being compiled in. Unfortunatley thats all it does. if( ::CoCreateInstance(CLSID_Pdf, NULL, CLSCTX_INPROC_SERVER, DIID__DPdf, (void**)&pDispatch) != 0 ) return f...
