I think this causing me problem because the second time I show a modal
dialog with a CDHtml control I see this and an exception:

CoCreateInstance of OLE control {8856F961-340A-11D0-A96B-00C04FD705A2}
failed.

>>> Result code: 0x800401f0
>>> Is the control is properly registered?

Thanks

I wasn't able to recreate either of the problems you are having. Can you
create a simple test that recreates a problem, and post the steps here.

That will be difficult to do, but I will try. First, let me outline
what I'm doing to verify it is correct in principle.

I have an MFC EXE and MFC DLL. The EXE calls a function in the DLL in
response to a user event, which in turn calls a second function to
display the modal dialog that has a CDHtmlDialog object for the HTML
heading.

Both DLL functions start off with a call to
AFX_MANAGE_STATE(AfxGetStaticModuleState()).

In the second DLL function call, I simply instantiate my CDialog object
that has a CDHtmlDialog member variable and then call the DoModal
method for it.

Thanks

If I understand what you are trying to do correctly, I would tell you to use
the WebBrowser control (IWebBrowser2 Interface) instead of embedding a
CDHtmlDialog in your CDialog.

Here is a good wrapper for the IWebBrowser2
http://www.codeproject.com/miscctrl/simplebrowserformfc.asp

Anyway, I don't think the fact that it's in a DLL should cause any
problems, but I am not a 100%.
Here are some questions: Are you creating the CDHtmlDialog as a child
dialog, using the Create method? Would the same thing happen if you dialogs
were in the exe instead of the DLL?

I'm using the Create method. The core problem is that someone is
calling CoUninitialize on my main thread (the one that called
AfxOleInit) many times usually it is balance with a call to
CoInitialize. If I make sure and call CoIniatialize right before
calling DoModal the problem goes away...but, I don't understand why I'm
seeing in the debugger that ole32!CoUninitialize breakpoints are hit so
many times. Here are some examples:
