I've replicated the code you have here, but just condensed it to the
main () function just so I could try and load an URI. I get an error too
(NS_ERROR_UNEXPECTED 0x8000ffff) on nsIWebNavigation::LoadURI (). So, I
still believe you have to implement the bare minimum for embedding Gecko
as stated in their embedding guide...even if you don't want a UI, I
think it still needs the other implementations. Also, you don't have to
implement a pretty interface, just get the guts going. Can any Gecko
Gurus confirm or deny this supposition? I've posted the code I used
below (Sorry, not commented, just thrown together ;-)):
int main (int argc, char *argv[])
{
nsresult rv = NS_OK;
nsString sBinDir;
nsString sURI;
nsCOMPtr<nsILocalFile> pCOM_lf;
nsCOMPtr<nsIWebBrowser> pCOM_wb;
nsCOMPtr<nsIWebNavigation> pCOM_wn;
sBinDir.Assign (NS_ConvertUTF8toUTF16
("C:\\Dev\\Source\\mozilla\\ff-release-shared\\dist\\bin"));
NS_NewLocalFile (sBinDir, PR_TRUE, getter_AddRefs (pCOM_lf));
rv = NS_InitEmbedding (pCOM_lf, nsnull);
pCOM_wb = do_CreateInstance (NS_WEBBROWSER_CONTRACTID, &rv);
pCOM_wn = do_QueryInterface (pCOM_wb, &rv);
sURI.Assign (NS_ConvertUTF8toUTF16 ("http://www.google.com";));
rv = pCOM_wn->LoadURI (sURI.get (), nsIWebNavigation::LOAD_FLAGS_NONE,
nsnull, nsnull, nsnull);
NS_TermEmbedding ();
return (0);
}
