Hello everyone!
Here is my question:
When embedding Mozilla , folling the codes of MFCEmbedded, I Impelement
the nsIWebProgressListener interface , and I want to get the title of a
page to determin whether it goes right in function OnStateChange.Here
is
my codes:
if (progressStateFlags & STATE_START)
{
if (progressStateFlags & STATE_IS_NETWORK)
{
mTotalRequests = 0;
mFinishedRequests = 0;
}
if (progressStateFlags & STATE_IS_REQUEST)
{
++mTotalRequests;
}
}
else
{
if (progressStateFlags & STATE_STOP)
{
if (progressStateFlags & STATE_IS_DOCUMENT)
{
if ( (mFinishedRequests + 1) <=mTotalRequests )
{
++mFinishedRequests;
}
}
}
}
if ( (progressStateFlags & nsIWebProgressListener::STATE_START)
&& (progressStateFlags &nsIWebProgressListener::STATE_IS_DOCUMENT)
)
{
return NS_OK;
}
if (!progress)
{
return NS_OK;
}
else
{
PRBool docLoading;
progress->GetIsLoadingDocument(&docLoading);
if (docLoading == PR_TRUE)
{
//OutputDebugString(_T("Our page is stillloading...\n"));
return NS_OK;
}
}
if ( (mFinishedRequests == mTotalRequests)
&& ( (progressStateFlags &nsIWebProgressListener::STATE_STOP) |
(progressStateFlags &nsIWebProgressListener::STATE_IS_NETWORK) ))
&& (status == NS_OK))
{
OutputDebugString(_T("Our page is now loaded...\n"));
//...
}
first time I kick unter key in the urlEntry , function OnStateChange
was called only once, only mTotalRequests became 1,and the varible
mFinishedRequests got unchanged.
second time I kick unter key in the urlEntry, first the varible
mFinishedRequests became 1 and (progressStateFlags
&nsIWebProgressListener::STATE_STOP) |
(progressStateFlags &nsIWebProgressListener::STATE_IS_NETWORK)
became true ,but status was not equal to NS_OK,so I can't see the
sentence "Our page is now loaded...\n" in the output.
then function OnStateChange was called , mTotalRequests=1 and
mFinishedRequests =0. It began the second request.
who can help me?
