Hello all,

I need some help with CHtmlView.

What I need to achieve :- I am creatying an HTML file in memory and need to preview it to the user.

Current plan :- Create a temporary HTML file and open it in Internet Explorer

Alternate plan :- Create a frame window, with a CHtmlView and jump up this frame window. Now I need to transfer my in-memory HTML code into this CHtmlView. How do I do that please?

Warm regards
Buster

I found that the easiest way was to create the temp html file and then navigate to that. There didn't seem to be an easier way to do it. I came across a few ideas in the ATL mailing list archives but nothing that seemed easy to implement.

If you want to load a HTML string from memory:

HRESULT hr;
IDispatch *pIDispatch = GetHtmlDocument();
IHTMLDocument2 *pIDoc;
IHTMLElement *pIBody;
hr = pIDispatch->QueryInterface(IID_IHTMLDocument2, (void**)&pIDoc);
hr = pIDoc->get_body(&pIBody);
hr = pIBody->put_innerHTML(_bstr_t("<b>Hello world</b>"));

(Error handling and clean up left as an exercise Big Grin | :-D

hi
I used the datetimepicker control and I added a member variable for this control, but when i use UpdateData(); the problem occured with any date befor 1969-12-31. is it a bug in vc6? can I use this control for date before 1969-12-31 and how?

Best Regards Smile | :)

I use this control without any problems.
Even the year 1817 is reachable.
Your accompanying code must be teh problem.

Hi,

Your problem is that the MFC CTime class actually uses the mktime() call internally. If you look at the definition of mktime() you'll see that it uses a time_t, which is a floating point value representing the number of seconds since, you guessed it, Jan 1 1970. The problem here is the fact that you're mapping your control to a CTime value. Open the ClassWizard and delete the mapped variable. Add it again, but make sure you select COleDateTime from the Variable Type combo. This should give you a much larger range of values.

Hope this helps.
