Firing the onChange event for a IHTMLSelectElement

[transactive_ryan]

Hi All,

I'm trying to fire the onchange event for a SelectBox on a webpage (IE
6.0), the selectbox is automatically selected and filled through the
below code, however I cannot get the event to fire, is anyone able to
help out with this?

// This code works, as it selects the correct value in the drop down
pSelectElement->put_value(value);

VARIANT v_event;
v_event.vt = VT_DISPATCH;
hResult = pSelectElement->get_onchange(&v_event);
if(FAILED(hResult))
asm nop // for debugging

IDispatch *pDispatch = v_event.pdispVal;
unsigned int iVal = 0;
hResult = pDispatch->GetTypeInfoCount(&iVal);
if(FAILED(hResult))
asm nop

// iVal is 1 now

/*ITypeInfo FAR* pTypeInfo;
hResult = pDispatch->GetTypeInfo(0, LOCALE_USER_DEFAULT, &pTypeInfo);
if(FAILED(hResult))
asm nop*/

wchar_t *callName = L"onChange"; // name of the function
DISPID methodID;
hResult = pDispatch->GetIDsOfNames(IID_NULL, &callName, 1,
LOCALE_USER_DEFAULT, &methodID);
// this returns -1 in methodID, and a huge negative value in hResult
if(FAILED(hResult))
asm nop

If anyone can help me out here, or has a better solution for firing the
onChange event (or any events for that matter) it would be greatly
appreciated if you could let me know.

Cheers,
