Can anyone tell me the correct mshtml interface so that I can read/set the
values and names of comboboxes and drop down lists displayed in a browser.
I've tried Gambit's...
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 )
{ TComInterface<IHTMLInputElement>Input;
Disp->QueryInterface(IID_IHTMLInputElement,(LPVOID*)
&Input);
// AND Also tried
//TComInterface<IHTMLInputTextElement>Input;
//Disp->QueryInterface(IID_IHTMLInputTextElement,(LPVOID*)
&Input);
if( Input )
{ ...
... but it just skips over my combo boxes displayed in the browser. I need
to be able to see the combo box's name and set/read the selected value of
the box.
Thanks for looking.

did not read the MSHTML interface documentation, did you?
msdn.microsoft.com/workshop/browser/mshtml/reference/ifaces/interface.asp
ComboBoxes are not handled by the <input>HTML tag to begin with, so
IHTMLInputElement is the wrong interface to use. ComboBoxes are handled by
the <select>HTML tag instead, and thus you should be using the
IHTMLSelectElement interface instead. The individual items of the list are
contained in <option>tags inside the <select>so you can use the
IHTMLSelectElement's item() method to retreive the IHTMLOptionElement
interface for each item in the list.

Of course...
I did read the documentation but got stuck thinking the edit component of
the combobox would be inherited from InputElement rather than SelectElement.
Thanks for the help - once again.
