Sure it is. I started using it some 15 years ago.

This makes no sense. If you are wanting to edit the HTML, use URLDownloadToFile(). You can then plug the contents of the file into the edit control. Using the alternative IHTMLInterface would only complicate matters.

my whole intention is to extract data from a html page so it would be easier to load the html instead of the file !! i have done this in visual basic 6 but i need to do it for a project that is visual c++ 6 and so far i just get unrleated answer and no example!!! i think this the nature of visual c++ programers unlicke visual basic programmers!!

I've given you more than enough information to solve your problem. As a matter of fact, you've been given several solutions to the same problem. That's very gratuitous in my book.
This retrieves all of the <FONT> elements:
IDispatch pDisp2 = m_ctrlBrowser.GetDocument();
pDisp2->QueryInterface(IID_IHTMLDocument2, (void **) &ptrHTMLDocument);
BSTR pBURL = SysAllocStringByteLen(NULL, 1024);<br />
ptrHTMLDocument->get_URL(&pBURL);<br />
ptrHTMLDocument->get_all(&ptrHTMLElements);
ptrHTMLElements->get_length(&lElements);
VARIANT varName;<br />
varName.vt = VT_BYREF | VT_I1;<br />
varName.pcVal = "FONT";<br />
VARIANT varIndex;<br />
varIndex.vt = VT_I4;<br />
varIndex.lVal = 1;<br />
ptrHTMLElements->item(varName, varIndex, &pDisp3);
pDisp3->QueryInterface(IID_IHTMLElement, (void **) &ptrHTMLElement);
ptrHTMLElement->get_innerHTML(&pBURL);<br />
ptrHTMLDocument->Release();

DavidCrow thank u for u code. But i want the get the whole html of a specific url and place it in a textbox just like i showed u in visual basic 6. I do not want to retrive font elements!!!

Then do as I've already suggested. Use URLDownloadToFile() to download the HTML to some temporary file. You can then plug the contents of the file into the edit control. It's a very simple procedure.

See here. Once you have a file, you can then open the file using any number of methods (e.g., CFile, FILE*, CreateFile()).

HTML from where ? if it's from the web, David gave you a good starting point.
else, if it's simple html text, just do a SetWindowText of the HTML code to the CEditBox; but it will not be formatted.

 Hi,
I am using Visual C++ 6.0 MFC and I created a dialog based app that has several different dialog classes. I decided that I wanted to put each of my dialogs onto a tab control page. This I can do, but now when I click on my dialog command buttons nothing happens. I went into the dialog properties and changed them from popup to child and also the visible style check box and the four different combinations of them. I used the class wizard to define functions for OnNotify and OnChildNotify but these only fire when I click on the tab itself not the command buttons in the tab page. There is no WM_NOTIFY available through the class wizard. I have found information on how to create the tab control and how to get the dialog boxes to appear in the contorl but I can't find any good information about recognizing the event when a button on the tab page (dialog) is clicked. If anyone that can point me in the right direction it would be greatly appreaciated.

Hello
I'm currently interested in putting a 3D control (OGRE -a 3D engine-, namely) in a dialog box with other elements. So, you would insert that control in a dialog box, together with other things (buttons or even CHtmlView-derived classes) and it actually does work.
I have a problem, thought: I would like the control to be aware of the keyboard focus. Let me explain: in an edit box, for example, when the user clicks the edit box is selected and all keyboard actions go to the edit box. The same with for example CHtmlView.
My class currently inherits from CStatic, and I'm having real trouble making it capture the keyboard (interestingly, capturing the mouse has been easy!).
How could I solve this problem, so make my class act like, say, the CEdit class?
Thank you

Can't you change your class to inherit from CEdit, instead of CStatic?
Best,
Jun

Hello
Sure I can inherit from anything, but unfortunately it doesn't seem to help: taking CEdit as base class still doesn't make the static get the keyboard focus... Annoying!
I've found a workaround: instead of creating the control in a static, I create it in an EDITTEXT ... so, it does capture the keyboard when clicked, but has the normal behaviour of an edit text: it changes the cursor into a "I", it blinks, it has a border and worse it types in text when you press buttons!
Do you have any other ideas?
Thank you

Derive your class directly from Cwnd. That will give you the most flexibility.

Subclass it!

Hello
I'm poting you this message and sure you don't need to reply or help me, I would just be glad if you can 
As I told in the forum post, my aim is to develop an MFC-based object which would act like, for instance, CHtmlView: on the programmer side, the only action that would need to be done would be to call CMyClass::Create(dwStyle, rect, parentDialog, staticCtrlID) and this would create the control, in any kind of control (static text, edit box, ...). Also, the control would take over the default keyboard and mouse actions on the dialog and therefore, for example, clicking on the class "window" and then pressing the arrow buttons on the keyboard would only make the class take an action.
This is the point where I'm stuck: how can I make this class get created on any kind of static control and second (more importantly) how do I make it capture all actions once clicked on (and release it back once the user clicks somewhere else)?
Thank you

Hello
It's just to tell you that I've solved the issue... Here's how it goes:
Problem: when there's a control in a dialog box replacing a STATIC resource, it will lose focus as soon as a key is pressed (things move in the dialog box) and it will never receive the OnKeyDown call.
Reason: STATIC is not supposed to be doing input/output, as a result it cannot receive keyboard events. As a result, you won't receive the OnKeyDown call (even if you do put it in the message map) and any pressed key, since not captured by the STATIC, will get dispatched to the parent (the dialog box) and this will make it take the default action -changing the selected button.
Solution: in the class that wants to go into a STATIC, overload the PreTranslateMessage, OnLButtonDown and OnRButtonDown methods (you also need to specify the mouse actions in the message map). PreTranslateMessage shall check if( pMsg->message == WM_KEYDOWN ), and in this case call OnKeyDown followed by CWnd::PreTranslateMessage and return TRUE (so the message doesn't get dispatched). If not, it shall return whatever CWnd::PreTranslateMessage returns. In the mouse handling methods, call SetFocus to get the focus when clicked.
New problem: the call you do to OnKeyDown is ignored (in classes that inherit from our base class, at least).
Reason: Don't know why...
Solution: Create a new virtual OnKeyDown method which would have a different signature from the original method (for example, one that only takes the nChar argument) and call that one. Now, put the key handling stuff in that new OnKeyDown method.
The solution therefore doesn't require you to overload CDialog::PreTranslateMessage or do other things like that. Note that the modification done to PreTranslateMessage is also very small, which makes that the overall behaviour of the control as well as the dialog box remains the same...

Hi all, I'm currently performing the following sequence of actions:
- My prog creates a directory
- It opens an OLE link to an external program, which creates files in that directory
- the OLE link releases the dispatch driver
- The external program may quit
- My prog deletes the files from the directory
At this point, my prog tries to delete the directory, but it fails with the error message that another process is still using the directory.
Any ideas, please?
Cheers,
Steve.

Hi all.
I am using MFC, and I want to display a bitmap on a button. I created the resource and it appeared in the bitmap resources as IDB_BITMAP1. Now I added a button named m_opaque and added the followin code to the OnPaint function:
void HelloDlg::OnPaint()<br />
{<br />
if (IsIconic())<br />
{<br />
CPaintDC dc(this);
<br />
SendMessage(WM_ICONERASEBKGND, reinterpret_cast<WPARAM>(dc.GetSafeHdc()), 0);<br />
<br />
int cxIcon = GetSystemMetrics(SM_CXICON);<br />
int cyIcon = GetSystemMetrics(SM_CYICON);<br />
CRect rect;<br />
GetClientRect(&rect);<br />
int x = (rect.Width() - cxIcon + 1) / 2;<br />
int y = (rect.Height() - cyIcon + 1) / 2;<br />
<br />
dc.DrawIcon(x, y, m_hIcon);<br />
m_opaque.ModifyStyle(0, WS_CHILD|WS_VISIBLE|BS_BITMAP);<br />
m_opaque.SetBitmap( ::LoadBitmap(NULL, MAKEINTRESOURCE(IDB_BITMAP1)) );<br />
}<br />
else<br />
{<br />
CDialog::OnPaint();<br />
}<br />
}<br />
The code compiles but the image doesnt appear. what is the reason?

You are painting only when the window is minimized! 
Also setting the bitmap is not a "painting" function. That should be done during initialization not painting.

Adding these two line to the init dialog also doesnt show the picture????
m_opaque.ModifyStyle(0, WS_CHILD|WS_VISIBLE|BS_BITMAP);
m_opaque.SetBitmap( ::LoadBitmap(NULL, MAKEINTRESOURCE(IDB_BITMAP1)) );

You are painting in the OnPaint message of the dialog when the dialog is minimized.
If you want to draw the bitmap on a button that is child control of the dialog, you are not painting at the right place.
To draw a bitmap on a button, you can use the CBitmapButton class.
