IHTML question

Good-day,

I am writing a program in VC 6.0 that will automate input of text on a web page text box.  I am using the CWebBrowser2 control and here is the code that I am using:

MSHTML::IHTMLDocument2Ptr pDoc= m_web.GetDocument();  MSHTML::IHTMLElementCollectionPtr pAllElems= pDoc->all;
MSHTML::IHTMLInputTextElementPtr pTextInput= pAllElems->item("editbox_name");
pTextInput->value = "some text";

This code is working fine; my problem is that I have encountered a web page that has mulitiple frames, and I need to specify which frame to select before I can run this.
Any ideas?
Thanks very much.

You should get the frame from IHTMLDocument2.frames.item("frame name"), cast it to IHTMLWindow2 and get document from it. And after that get elements of this document and do with them whatever you want.

Could you give me an example as to how to use this. Lets say that the form name that I am trying to access is named "form1"

Thanks

Ok. I have 3 files:
1.html - contains frameset
2.html - contains form
IEManip.cpp - does all the work with them.

Here they are:
1.html
--------------------------------------------
<html>
<frameset>
<frame name="frame1" src="file://c:/2.html">
</frame>
</frameset>
</html>
============================================
2.html
--------------------------------------------
<html>
<body>
<form name="form1" action="about:blank">
<input name="i1" type="text">
</form>
</body>
</html>
============================================
IEManip.cpp
--------------------------------------------
#import <shdocvw.dll>
#import <mshtml.tlb>

int main(int argc, char* argv[])
{
  CoInitialize(0);
  {
    SHDocVw::IWebBrowser2Ptr pIE(__uuidof(SHDocVw::InternetExplorer));
    MSHTML::IHTMLDocument2Ptr pHTMLDoc;
   
    pIE->Visible = true;
    pIE->Navigate("file://c:/1.html");
    while(pIE->GetBusy())
      Sleep(100);
    pIE->GetDocument()->QueryInterface(&pHTMLDoc);

    MSHTML::IHTMLWindow2Ptr pHTMLWnd = (IUnknown*)pHTMLDoc->frames->item(&_variant_t("frame1"));
    MSHTML::IHTMLFormElementPtr pForm = (IUnknown*)pHTMLWnd->document->forms->item(&_variant_t("form1"));
    MSHTML::IHTMLInputElementPtr pInput = (IUnknown*)pForm->item(&_variant_t("i1"));
    pInput->value = "Test string";
  }
  CoUninitialize();
  return 0;
}
============================================

You should put 1.html and 2.html to the root of disk C.

Let me know if you have more questions about this.

This code looks great... just a few questions about it.  

1.  I would like to incorporate the ActiveX WebBrowser control inside a dialog box rather than IE.

2. I searched the HTML source code for this web page that I am trying to access, and there doesn't seem to be a <frame name> tag anywhere. Is there a default value I can use for this?

Thanks.

If you don't have frame names, then just select frame by its index.

Remove attribute name from frame tag from 1.html:
<frame src="file://c:/2.html">
And change:
MSHTML::IHTMLWindow2Ptr pHTMLWnd = (IUnknown*)pHTMLDoc->frames->item(&_variant_t("frame1"));
to:
MSHTML::IHTMLWindow2Ptr pHTMLWnd = (IUnknown*)pHTMLDoc->frames->item(&_variant_t(0L));


That's all you need.

> 1.  I would like to incorporate the ActiveX WebBrowser control inside a dialog box rather than IE.
Let's connect it to your code:
=====================================
MSHTML::IHTMLDocument2Ptr pDoc= m_web.GetDocument(); // This is what you have in the first line

//And this is the remaining
MSHTML::IHTMLWindow2Ptr pHTMLWnd = (IUnknown*)pDoc->frames->item(&_variant_t(0L));
MSHTML::IHTMLFormElementPtr pForm = (IUnknown*)pHTMLWnd->document->forms->item(&_variant_t("form1"));
MSHTML::IHTMLInputElementPtr pInput = (IUnknown*)pForm->item(&_variant_t("i1"));
pInput->value = "Test string";
======================================

Just you can get IWebBrowser2 interface from IE and from WebBrowser control. And it will always have document inside.

I can't seem to get this code to work.  For example, I load the www.yahoo.com page in my WebBrowser and have a button that is attatched to this code:

     
MSHTML::IHTMLDocument2Ptr pDoc= m_web.GetDocument();

MSHTML::IHTMLWindow2Ptr pHTMLWnd = (IUnknown*)pDoc->frames->item(&_variant_t(0L));
MSHTML::IHTMLFormElementPtr pForm = (IUnknown*)pHTMLWnd->document->forms->item(&_variant_t("f"));
MSHTML::IHTMLInputElementPtr pInput = (IUnknown*)pForm->item(&_variant_t("p"));
pInput->value = "Test string";

The yahoo page form name seems to be "f" and the input edit box is "p". But when I try to run this, the program crashes.

Any ideas?

thanks.

The problem here is that Yahoo page doesn't have frames. So you should simply get the form from the root document.

MSHTML::IHTMLFormElementPtr pForm = (IUnknown*)pDoc->forms->item(&_variant_t("f"));
MSHTML::IHTMLInputElementPtr pInput = (IUnknown*)pForm->item(&_variant_t("p"));
pInput->value = "Test string";
Sleep(5000);
pForm->submit();
