IHTMLSelectElement put_onchange syntax

Can someone please show me how I can fire an onchange event for a dropdown 
list after I select one of the items programatically?  My current code is:

   TComInterface<IHTMLDocument2> Doc;
        ActiveBrowser->Document->QueryInterface(IID_IHTMLDocument2,(LPVOID*)&Doc);
        if( Doc )
        {
            TComInterface<IHTMLElementCollection> All;
            Doc->get_all(&All);
            if( All )
            {
                long count = 0;
                All->get_length(&count);

                for(long idx = 0; idx < count; ++idx)
                {
                    TVariant item = idx;
                    TVariant index = 0;
                    TComInterface<IDispatch> Disp;

                    All->item(item, index, &Disp);
                    if( Disp )
                    {
                     WideString value;
                     int found;
                       TComInterface<IHTMLSelectElement> Input;
                       Disp->QueryInterface(IID_IHTMLSelectElement,(LPVOID*)&Input);
                       Value = "";

                        if( Input ) //  Found a Drop down box
                        {  IDispatch *ppvdispOption;
                           IHTMLOptionElement *ppvOption;
                           BSTR *pszOptText;
                           WideString name;

                           Input->get_name(&name);
                           AnsiString Name = AnsiString(name);

                           if(UpperCase(Name)==UpperCase(AnsiString(Field))) 
{
                           long i;

                           long length;

                           Input->get_length(&length);

                           for(i=0;i<length;i++)
                           {TVariant index = i;
                            Input->item( index, index, &ppvdispOption );
                            ppvdispOption->QueryInterface( 
IID_IHTMLOptionElement,(void **) 
&ppvOption);
                            ppvOption->get_text(&value);

                            AnsiString TValue = AnsiString(value);
                            Trim(TValue);

                            if(UpperCase(TValue)==UpperCase(Value))
                            {
                             Input->put_selectedIndex(i);  // Selects 
correct item from list

                             if(Special=='C')  // Control needs to fire 
onchange event...
                             {

                             TComInterface<IHTMLSelectElement> Input;
                             Disp->QueryInterface(IID_IHTMLSelectElement,(LPVOID*)&Input);
                             Input->put_onchange(index);

                            (etc)

This code does not appear to fire the onchange event.  I know it's because 
of the TVariant that I am passing to the event but I don't know what it's 
looking for,


Thanks for looking

You should wrap those in TComInterface so that you do not leak them.

Use a WideString instead so that you do not leak it.

> if(UpperCase(Name)==UpperCase(AnsiString(Field)))

Use AnsiSameText() instead:

    if( AnsiSameText(name, Field) )

Or, if you are using BCB 6+, then use WideSameText():

    if( WideSameText(name, Field) )

> Trim(TValue);

That has no effect.  Trim() does not alter the string that is passed to it.
It returns a new AnsiString instead:

    AnsiString TValue = value;
    TValue = Trim(TValue);

Or:

    AnsiString TValue = AnsiString(value).Trim();

Alternatively, if you are using BCB v6+, then Trim() has an overloaded
version for WideString:

    WideString TValue = Trim(value);

> if(UpperCase(TValue)==UpperCase(Value))

Again, use AnsiSameText() (or WideSameText()):

    if( AnsiSameText(TValue, Value) )

> TComInterface<IHTMLSelectElement> Input;
> Disp->QueryInterface(IID_IHTMLSelectElement,(LPVOID*)&Input);
> Input->put_onchange(index);

That will not work.  In order to trigger the event, you have to RETRIEVE the
event handler and then call it directly, but you are trying to ASSIGN the
handler instead (and not properly at that).  Use this instead:

    TVariant event;
    Input->get_onchange(&event);
    if( V_VT(&event) == VT_DISPATCH )
    {
        IDispatch *pEventDisp = V_DISPATCH(&event);
        if( pEventDisp )
        {
            DISPPARAMS Params = {0};
            TVariant Result;
            pEventDisp->Invoke(DISPID_VALUE, IID_NULL,
LOCALE_SYSTEM_DEFAULT, DISPATCH_METHOD, &Params, &Result, NULL, NULL)
        }
    }

Alternatively, use the IHTMLElement3::fireEvent() method instead:

    TComInterface<IHTMLDocument4> Doc4 = Doc;
    TComInterface<IHTMLElement3> Element = Input;

    if( (Doc4) && (Element) )
    {
        IHTMLEventObj *pEventObj = NULL;
        Doc4->createEventObject(NULL, &pEventObj);
        if( pEventObj )
        {
            TVariant Event;
            VARIANT_BOOL Canceled = VARIANT_FALSE;

            V_VT(&Event) = VT_DISPATCH;
            V_DISPATCH(&Event) = pEventObj;
            // configure pEventObj as needed ...

            Element->fireEvent(WideString("onchange"), &Event, &Canceled);
        }
    }
    else
    {
        // use the code further above ...
    }

> This code does not appear to fire the onchange event.

Of course not.  You are not even calling the event handler at all.

When I implement...

    TVariant event;
    Input->get_onchange(&event);
    if( V_VT(&event) == VT_DISPATCH )
    {
        IDispatch *pEventDisp = V_DISPATCH(&event);
        if( pEventDisp )
        {
            DISPPARAMS Params = {0};
            TVariant Result;

and get to the last line...

>            pEventDisp->Invoke(DISPID_VALUE, IID_NULL,
> LOCALE_SYSTEM_DEFAULT, DISPATCH_METHOD, &Params, &Result, NULL, NULL)

I get an arror that says

'An error has occured in the script on this page.

Line: 127

Char: 3

Error: 'options' is null or not an object

Code: 0

URL:  blah blah blah

Do you want to continue running scripts?


Do I need to define the parameters that we are sending?

Alas I am not good enough at DOM to    ' configure pEventObj as needed ...' 
in your second example.

Also, even if I do try to compile using the second example:

TComInterface<IHTMLDocument4> Doc4 = Doc;

// I get 'Undefined Symbol IHTMLDocument4'
//and then 'Cannot generate template specailization from 
TComInterface(T,piid)' on this line

 TComInterface<IHTMLElement3> Element = Input;

// and then 'Undefined symbol 'IHTMLElement3' here

Am I missing a header or something?

The error suggests that the C++ code is not supplying the event handler with
everything it needs, so please show the original HTML for the <select> tag
and its onchange event handler.

No, simply an outdated PSDK.  IHTMLDocument4 and IHTMLElement3 do not exist
in BCB v6 or earlier.  They were created after BCB 6 was released.  You will
have to define them manually (or upgrade to BDS 2006), ie:

--- MissingInterfaces.h ---

#ifndef MissingInterfacesH
#define MissingInterfacesH

#include <mshtml.h>

#ifndef __IHTMLElement3_FWD_DEFINED__
#define __IHTMLElement3_FWD_DEFINED__

#ifndef __IHTMLDocument4_FWD_DEFINED__
#define __IHTMLDocument4_FWD_DEFINED__
typedef interface IHTMLDocument4 IHTMLDocument4;
#endif  /* __IHTMLDocument4_FWD_DEFINED__ */

I copied most of it from BDS 2006's copy of mshtml.h.

The onChange event is accessing the 'this' pointer.  Try passing the
IHTMLSelectElement as a parameter when calling Invoke(), ie:

    if( pEventDisp )
    {
        TVariant Result, Arg = (IDispatch*) (IHTMLSelectElement*) Input;
        DISPID Id = DISPID_THIS;
        DISPPARAMS Params = {&Arg, &Id, 1, 1};
        pEventDisp->Invoke(DISPID_VALUE, IID_NULL, LOCALE_SYSTEM_DEFAULT,
DISPATCH_METHOD, &Params, &Result, NULL, NULL);
    }
