Not sure if this is what you mean, but you can call javascript from C++
using the following code:
LPDISPATCH document = 0;
wbBrowser->ControlInterface->get_Document(&document);
IHTMLDocument* htmlDocument = 0;
HRESULT hr = document->QueryInterface(IID_IHTMLDocument,
(void**)&htmlDocument);
if (SUCCEEDED(hr)) {
DISPID saveID = 0;
OLECHAR FAR* saveName = L"doSave"; // Name of the JS function
LPDISPATCH script = 0;
htmlDocument->get_Script(&script);
hr = script->GetIDsOfNames(IID_NULL, &saveName, 1,
LOCALE_SYSTEM_DEFAULT, &saveID);
if (SUCCEEDED(hr)) {
// Invoke function
// I am assuming there are no arguments. Read about
IDispatch::Invoke
DISPPARAMS noArgs = {NULL, NULL, 0, 0};
hr = script->Invoke(saveID, IID_NULL, LOCALE_SYSTEM_DEFAULT,
DISPATCH_METHOD, &noArgs, NULL, NULL, NULL);
}
script->Release();
htmlDocument->Release();
}
document->Release();
Hope it helps,
