pass info from an MFC app into html script?
Hello, this question may be for Dan Rollins!!! I saw a posting where he explained how to get info from html to MFC. I already know how to do tyhat, but I need to know the best way to put data back into a form.
I have an edit field in my html document in a form section and I need to set it to a value from MFC before the page appears. I have a CHtmlView.
I have been struggling with this for quite awhile and it is important that I solve this as soon as possible. Any help would be greatly appreciated!!!

Thanks Dan, unfortunately, I am not using smart pointers. I can go ahead an use them, but it may be easier if I do not have to. Is there a way to do this without using them? If not, I will go ahead and implement your suggestion.
Thanks,
Tony

Dan, I did implement a variation with smart pointers and it works. I am still curious if there is a way to do this without them, but my problem is solved never the less. Thanks!!!

Dan,
I am still curious if there is a way to do this without smart pointers, do you know of anyway to accomplish that?
I tried to accept and it said, "You may not accept this answer" all in red!!! I would love to accept, but why can't I?
Thanks,
Tony

It seems to have accepted. Tahnks.
As to not using smart pointers...
Why?
Working with COM objects in C++ is very difficult. The language has no native support for the idea of late-binding to objects that were not accessible at compile-time (unlike Visual Basic, JavaScript, C#, and all othermodern programming languages). So the people at Microsoft came up with a way to translate an IDL file into a compiler-usable .H file and the resulting code is much more readable and usable than alternative methods.
To be honest, COM programming is not my forte... I just look for example code, try to find matching documentation, and then try various things until something works. The *last* thing I want to do is find away to stop using something that makes programming easier :)

More than likely, you are getting the page from a website and you want to pre-fill some of the input itmes. You can't actually do it *before* the page is displayed, but you can do it a millisecond afterwards, which is usually just as good:
1) You can't do anything until the OnDocumentComplete() fn is executed (you probably know that).
2) I assume you are allreday using #import to get access to the HTML DOM smart pointers
3) You need to know the ID or name of the target field. You must use a text editor to eyeball the html source. You will find something like:
<form name=xxxx ...>
Enter your Last Name here: <input type=text name='lastName' size=30>
...
</form>
so the target ID is "lastName". You can use code like the following to change its value:
MSHTML::IHTMLDocument2Ptr pDoc= m_ctlBrowser.GetDocument()
MSHTML::IHTMLElementCollec
int nCnt= pAllElems->length; // eyeball check. It WORKS!
MSHTML::IHTMLInputTextElem
pElem->Putvalue ("Buford Brimly" );
4) You are done. Award points an select "Execllent" for the grade :)
