I'm having a very similar problem, but with BCB 2006.  I'm upgrading a 
project from BCB 5, and am getting the following error:

[C++ Error] MyFile.cpp(38): E2034 Cannot convert 'void (_fastcall * 
(_closure )(TObject *,IDispatch *,Variant *))(TObject *,IDispatch *,Variant 
*)' to 'TCppWebBrowserDocumentComplete'

with this function definition:
void __fastcall navigateToOddsPageComplete(TObject *Sender, LPDISPATCH 
pDisp, Variant *URL);

on this line:
browser->OnDocumentComplete = navigateToOddsPageComplete;

One other thing.. I changed all my 'TVariant's to 'Variant' during the 
conversion.  I also noticed that the error says IDispatch * instead of 
LPDISPATCH, and I tried to replace it, but with no luck.  (Also, the 
automatically generated functions by BCB use LPDISPATCH).

Hopefully some can help with Hans' and my problem.

Thanks,

Toby

Hi Hans,

I figured it out finally and it solved my problem, I assume yours is similar 
(but not quite the same).

All I had to do was change my function definitions from:
void __fastcall navigateToPageComplete(TObject *Sender, LPDISPATCH,  pDisp, 
Variant *URL);
to
void __fastcall navigateToPageComplete(TObject *Sender, LPDISPATCH,  pDisp, 
VARIANT *URL);

(notice the Variant at the end is capitalized)

Since you're using TWebBrowser, which has OleVariant, I'm not sure what you 
would have to change it to, but I found out the answer by looking in 
SHDocVw_OCX.h and finding the typdef for TCppWebBrowserDocumentComplete.

I looked in SHDocVw.hpp, which I think is the TWebBrowser equivilant, it 
had:

typedef void __fastcall (__closure 
*TWebBrowserDocumentComplete)(System::TObject* ASender, const _di_IDispatch 
pDisp, OleVariant &URL);

so, you may want to try to change your function from (what I assume looks 
like this)

void __fastcall WebBrowser1DocumentComplete(TObject *Sender,const IDispatch 
*pDisp,OleVariant &URL)

to

void __fastcall WebBrowser1DocumentComplete(TObject *Sender,const 
_di_IDispatch pDisp,OleVariant &URL)

or use TCppWebBrowser (if it's available) and do the same as I did.

Hope you get it going,

Toby

That does it exactly.

Great that you took the time to find out.

Thanks.

Hans.
