Hi Experts,
I want to display html in htmlview And I wrote some code for it But when I try to get pointer to html document it returns NULL value.This is :
// Get a pointer to the HTML Document Object Model's interface
IDispatch * pDisp = GetHtmlDocument();
And the code is
void CDisplayBody::OnNavigateCo
mplete2(LP
CTSTR strURL)
{
CString pszText="<html><head><body
>Hi How r u</body></head></html>";
if (GetBusy()) // See if it's busy with something else
Stop();
// Get a pointer to the HTML Document Object Model's interface
IDispatch * pDisp = GetHtmlDocument();
if (!pDisp)
return;
IHTMLDocument2* pDoc;
if (SUCCEEDED(pDisp->QueryInt
erface( IID_IHTMLDocument2, (void**)&pDoc )))
{
// Empty URL and parameters opens the current document
CComBSTR bstrURL;
CComVariant varDummy;
pDoc->open(bstrURL, varDummy, varDummy, varDummy, NULL);
// Create a safearray to store the HTML text
SAFEARRAY *pSA;
SAFEARRAYBOUND saBound = {1, 0};
pSA = SafeArrayCreate(VT_VARIANT
, 1, &saBound);
// Copy the HTML into the one and only element
VARIANT *pVar;
CComBSTR bstrHTML = pszText; // Load the text
varDummy = bstrHTML; // .. into a variant
SafeArrayAccessData(pSA, (void**)&pVar); // Access safearray data
pVar[0] = varDummy; // Set the text data
SafeArrayUnaccessData(pSA)
; // Release access
// Write the HTML as the document's new text
pDoc->write(pSA); // Overwrite HTML
pDoc->close(); // Update browser
SafeArrayDestroy(pSA); // Finished with the safearray
pDoc->Release(); // Don't forget to release the reference
}
}
What is the problem .
