Hello!

I have html page with content something like that
...
<form action="okhtml.php" method="post">
<input type="text" maxlength="25" name="a1" value="">
<textarea name="message" rows="20" cols="77"></textarea>

<input type="submit" name="ok" value="Ok">
<input type="submit" name="cancel" value="Cancel">
</form>
...

I want to make a program that automaticly presses "Ok" or "Cancel" button
and i can do that, but problem is with parameter "value", because this
parameter is not passed to okhtml.php. How can I solve this problem?

Here is source code:

...
if(SUCCEEDED(HTMLDocument->get_all(&pAll))) {
  TVariant name;
  TVariant index;
  IDispatch *pDisp = NULL;

  name = "ok";
  index = 0;
  pDisp = NULL;
  if(SUCCEEDED(pAll->item(name,index,&pDisp))) {
     if(pDisp) {
       IHTMLInputElement *pInpEl=NULL;

if(SUCCEEDED(pDisp->QueryInterface(IID_IHTMLInputElement,(LPVOID*)&pInpEl)))
{
          IHTMLFormElement *fe=NULL;
          pInpEl->get_form(&fe);
          if(fe) { fe->submit(); fe->Release(); }
...

Thank you, MrLapkoks

IHTMLFormElement::submiot() does not send the value of any submit buttons at
all.  Try calling the click() method on the particular button that you want
instead, ie:

    #include <utilcls.h>

    TComInterface<IHTMLElementCollection> pAll;
    if( SUCCEEDED(HTMLDocument->get_all(&pAll)) )
    {
        TVariant name = "ok";
        TVariant index = 0;

        TComInterface<IDispatch> pDisp;
        if( SUCCEEDED(pAll->item(name, index, &pDisp)) )
        {
            TComInterface<IHTMLElement> pEl;
            if( SUCCEEDED(pDisp->QueryInterface(IID_IHTMLInputElement,
(LPVOID*)&pEl)) )
                pEl->click();
        }
    }
