OK, 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.

Examples exist on MSDN and likely here on CodeProject as well. Did you search at all?

Same level? Can't you read? The Sample/Example code you ask for is free for the "reading" on MSDN like I told you three times now. Telling you where you can find what you asked for is not a "flame". If you really want to be flamed just let me know.

Use either the Navigate() or Navigate2() method.

Most, but not all, reside in the \Windows\System32 folder. However, there's rarely a need to know such information. Once a control has been registered with the OS, its path is mostly irrelevant.

Once you added the component ( as david wrote ), you can use the IHTMLDocument2 interface to access the HTML document, and directly write HTML code ( text ) to the document.
if you want to navigate to an existing document ( on disk or from the web ) you need to Navigate from the IWebBrowser2 interface.
do a little explorating on CodeProject, you will find pretty much what you want.

I have been confused with the following way of programming. please help me.
In my project I have a frame window and as its part 3 classes. A treeview , a window and a HTML control. Through the window I can select some directories. As soon as the selection is made the tree view must display all the HTML files in that directory. When clicking on the HTML file name in hte tree control it must be displayed in the HTML control. To carry I have used splitter windows. Now the problem comes. I dont know How to organise the classes and where to write the event handler!
As an example how can I pass the button click event in the window to the tree control. Or a click event in the tree control to the HTML control. Though these 3 are seperate classes and their objects are not related each other, it makes me confused! (I would like to write the event handler for each class in that class itself and I dont want to mess up the frame window with lots of code....)
could you please help me? Thanks in advance..
Lloyd.
