You export regular functions just the way you used to when the DLL hadn't MFC support: either with __declspec(dllexport) or resorting to .DEF files. Also, it helps having these functions declared as extern "C" so that you don't have to mess around with name decorating.

How can i catch the events fired by an ActiveX control without using Class Wizard ?
I'm creating the controls at runtime that's why i can't use the ClassWizard to create the Event Sink Map.

If creating another AcitveX control is your cup of tea, then you may try to use my class XYDispDriver to handle events. Basically, you create another control as your event handler (you can use ATL or MFC to create the event handler control). Please see my articles for details.
Warning: It only works with non-GUI controls (and the interface has to be derived from IDispatch) and it has been voted the "most hated" method by some ATL "experts".

I'm not creating another control. I create various CWebBrowser controls in a form view and need to catch the DocumentComplete event but i can't use the EVENT_SINK_MAP macros because i'm creating the controls at runtime.

You'll have to sink your own events. Have a look at knowledge base article Q246247 for starters.

This is an offer of encouragement. I had the same problem and worked for several weeks trying to find a good solution. I finally gave up. All the examples and info I could find seemed to assume you know the object at design time.
Runtime discoverable event sinks turned out to be pretty difficult for me. By using the TypeLib calls I was able to get the information for the sink, I could never get the Advise call to work, however.
Please let me know if you find a solution.
Good Luck.

Hi all,
Does any body have samples or explanations on how to do this :
A picture is shown in a scollview. When the picture is "bigger" than
the client area, scrollbars appear.
The user can drag a rectangle over the picture. When the rectangle reaches
the border of the client area, the view should scroll in order to allow the
rectangle to reach hidden parts of the picture.
I succeeded in doing this, but I still have a problem to solve :
when the view scrolls, the rectangle doesn't stay at the client
area border ; it scrolls with the picture... 
Any idea about the origin of this problem ?
Thx in advance for your help,
Jeje

This is probably because you are using the client coordinates. In such cases I use the CScrollView::GetScrollPosition and then I'm calculating the rectangle. That is if your top/left corner of your rectangle is out of your client area it is clipped.
Hope this helps.

Can you please give me more details ? 
Do you have any sample code for this ?
Anyway, thanx widi for this info.
I'll investigate this way.

Tanx a lot !
I'll check it asap to see how you proceed.
Nevertheless, I already almost succeed... 
In fact I redraw the rectangle and the client area in the OnTimer() function
instead of in OnMouseMove(). SO now, the rectangle stays at the client area
border, but now the problem is that the redraw is not perfect : sometimes
you can see 2 rectangles instead of only one.
Maybe I'll find the solution in the samples you sent !
Thx again,
Jeje.

I guess I missunderstood your question, sorry.
If you don't want the Rectangle to scroll in your view you can do that:
// this is declared in your class header file
CRect m_rect; // this is the rect you draw
// this goes where you paint your rect
CRect rc(m_rect);
CPoint pnt;
pnt.x = GetScrollPosition(SB_HORZ);
pnt.y = GetScrollPosition(SB_VERT);
rc.OffsetRect(-pnt.x, -pnt.y);
// pDC is your device contect which you get here
pDC->Rectangle (rc);
I think that is what you wanted.

I have a modeless dialog that is created and popped by an SDI application.
The problem is that the dialog is always topmost. I would like the SDI app to be topmost when I click in its window, placing the popup behind it.
Should a modeless dialog behave like this?
Cheers,
/Fredrik

Try setting CWnd::GetDesktopWindow() as the parent of your modeless dialog, instead of your main window.

What do you want? That the mainframe will be topmost, or the dialog?

I want the window I click in to be topmost.
Using CWnd::GetDesktopWindow(), as Joaquín wrote in his post, works fine.
Passing the this pointer to CDialog::Create() makes the dialog be always topmost.

Hello everybody!
Help me in follo...
How I can runtime change values of margins of page to force to print from the edge of page?
Best regards,

When you OnPrint handler is called, the printable area of the page is in the CPrintInfo objects member var m_rectDraw. Your OnPrint should use the values in this to decide wher to print on the page. To give yourself margins, setup a dialog that lets you enter the margin values, and then configure m_rectDraw at the start of the OnPrint procedure to take the margins into account:
int xl = (int)(pDC->GetDeviceCaps(LOGPIXELSX) * g_LeftMargin) ;
int xr = (int)(pDC->GetDeviceCaps(LOGPIXELSX) * g_RightMargin) ;
int yt = (int)(pDC->GetDeviceCaps(LOGPIXELSY) * g_TopMargin) ;
int yb = (int)(pDC->GetDeviceCaps(LOGPIXELSY) * g_BottomMargin) ;
pInfo->m_rectDraw.left += xl ;
pInfo->m_rectDraw.right -= xr ;
pInfo->m_rectDraw.top += yt ;
pInfo->m_rectDraw.bottom -= yb ;

The given method reduces m_rectDraw! And whether probably will increase m_rectDraw so to clean margins absolutely?

I think this is very Simple Question but I am new babie  .
In the SDI application. I draw something on the client area. I want to save this as a BMP and some other formats(GIF, JPEG . . .). So that this image can be open in any other software.
My primary goal is to save it as BMP format.
I want to do this without using any other's library. And also without using MFC (If possible, I hope)  .
Thanks in advance.
Some sample code will help alot.

The answer is many many lines of code and if you want an answer I think you have to take a look at some classes or something that do what you want to do and then ask here if you'll get problems when trying to do something similarly!

Actually it's damn easy. Just use GetWindowDC to get a handle to the windows device context and use GDI+ to save the image.

My 'Doodle' article shows how to use GDI+ to save an image to disk in different formats, the CXImage class also on CP shows a way to do it which doesn't involve downloading the SDK or relying on a DLL. Use GetWindowDC to get a device context you can use to grab the contents of the window. Just remember to make the Image you create the same bit depth as the screen, you can use GetDeviceCaps(BITSPIXEL) on the DC you get back from GetWindowDC to figure out what you need.

Hi,
Reading through the sea of documentation, I haven't been able to work this out... 
I would just like to add a button to the Internet Explorer toolbar and possibly some other applications. Now what I want is that when you click this button my code should be executed (and that piece of code will probably interact with IE somehow).
Can any one point me in the right direction as to where I can find information on the topic? Or if any one is willing to share som brief info on how to go about it...?
Thx, all help is greatly appreciated,
/Tommy
