C / C++ / MFC

I found various articles about creating and sending emails and about sending attachments.
However I need something simpler: I have an email address and want the resident mail system to create an email with the normal user interaction, i.e. my contribution is only waking the mail service and supplying the address.

It has to be in C++, dialog-oriented (non-SDI, non-MDI).

Have a look at Articles on MAPI. You can't guarantee that a MAPI client is available however.

Thanks, but my program does not have the message content to send.
In fact, I have only an email address in my hand.

The simpliest way is to use the ShellExecute() function, specifying the email address in the lpFile parameter

ShellExecute (NULL, "open", "mailto:who@where.ever", NULL, NULL, SW_SHOW);

You can also specify the subject, cc, and bcc in the lpFile parameter

ShellExecute(NULL, "open", "mailto:who@where.ever&cc=you@them.org&bcc=them@you.org&subject=hello", NULL, NULL, SW_SHOW);

If you want to add text or attachments then have a look at SIMPLE MAPI

Thank you; this is obviously the simplest solution.
Exactly, what I needed in this situation.

One remark: the show comman flag (SW_SHOW, or whatever else) has no effect in this case.
The documentation states, that it is only for the case, then an executable file is specified.
I tested it with "mailto", and it makes no difference.

I'm quite partial to this. A good place to start, at least.

You left me high and dry and changed me You lied to me and now i’m angry...

losing mouse events, help?

23-Jan-05 20:25

It appears to be an elegant solution, but it shoots a magnitude farther than I can use in the given context.

Thanks anyway.

Hi,
I am seeing "mouse up" messages disappear in the main event loop of my app and wondered if anyone's seen this problem before or has an idea what's going on?

Details:
The app has a custom event loop which gives time to some OpenGL display code and I have used PeekMessage with PM_NOREMOVE to see when there is a "mouse up" message in the queue. What I have found is that the calls to PreTranslateMessage and DispatchMessage can cause the "mouse up" message to vanish from the queue.

Summary of event loop for reference:

while(!quit)
{
    while(::PeekMessage(&msgCur, NULL, NULL, NULL, PM_REMOVE))
    {
        // ... extra control logic ...
        if(!PreTranslate(&msgCur))
        {
            ::TranslateMessage(&msgCur);
            ::DispatchMessage(&msgCur);
        }
        // ... more control logic ....
    }
    // ... more control logic ...
}

Any help appreciated.

Rob.

Global Variables in VC++ 6

Hello.
I'm new in C++ Programming and want to write an application wich is able to process Bitmap files.
I try to use the MFC to get a Windows program.

I have a big Problem with my variables:
So I have a file called CADoc which loads the Bitmap in memory, a CAView which shows it in a Window and a CACutBmp (a modal Window) where the user should be able to give the top left corner and width amd height of the area he wants to process to cut a rectangle out of the bitmap.

CACutBmp is started in the CADoc file... so an Object of CACutBmp is builded and the source Data is given to the modal Window... But if i want to cut the Window it must be possible to give the data back to the CADoc Class...

Thats my problem. I dont find a way to do so.
Can somebody here explain me how to use global variables properly in a MFC Based Application ?
Is there a better way then global variables to pass Data from one Class to another ?

Excuse me if the question is unclear or too noobish, but i would really appreciate any suggestions to get this problem solved.

Best regards,
Crypt.

I just went through a similar problem.
Do an artical search for "sendmessage". The first artical listed is very good on how to use send and post message between classes, as well as using pointers for other classes.

Hope this helps

Hi John.
Thank you for the fast answer... but I don't find the article you mentioned... can you give me another hind how to find it Smile | :)

Cant u pass a structure as a reference to the CACutBmp class from within th doc that the user modifies ?

Hi act.
Maybe that is what i should do... but i really do not know how to do it... Is it possible to find somewhere an example wich gives some further explanations on the how to ?

You *may* be overcomplicating the issue.

You have CADoc, which hold CABmp.

You have a command IDC_CROP which you want
to pop up a box, input some coords, and crop
the bitmap.

In header.

class CADocument : public CDocument
{
    ....
    CABmp m_Bmp;
    ....
    afx_msg void OnCrop ();
};

In Cpp

...
// Message map
ON_COMMAND(IDC_CROP, OnCrop)
...

// Function
void CADoc::OnCrop ()
{
    // Initialise the dialog.
    CADlg dlg (AfxGetMainWnd ());
    dlg.m_pBmp = &m_ABmp;
    dlg.m_rcBmp.SetRect (0,0, m_ABmp.GetWidth (), m_ABmp.GetHeight ());

    // Use the dialog to set a crop rectangle.
    if (dlg.DoModal () != IDOK)
        return;

    m_ABmp.Crop (dlg.m_rcBmp);

    SetModifiedFlag (TRUE);
    UpdateAllViews (); // Let the views know to redraw, using the new, leaner bitmap.
}

Just my thoughts. And there's a bunch to fill in...

UpdateAllViews was a good tip too !
It's just working perfect for me, much better then UpdateWindow amd Invalidate and this stuff!
But i had to use UpdateAllViews(NULL) to make it work...
No idea why but no I'm happy Smile | :)

...

Many Thanks again Iain,
Helge.

If you look at the docs , it defines UpdateAllViews as:

void UpdateAllViews( CView* pSender, LPARAM lHint = 0L, CObject* pHint = NULL );

The pSender is an optimisation if you are calling this function from
a View.

void CMyView::OnPropagateAChange ()
{
    CMyDoc *pDoc = GetDocument ();
    ....
    pDoc->UpdateAllViews (this);
}

That would redraw all views of that document except this one. I've never needed
to call with anything other than NULL, but I can see why you *might*.

The other parameters are useful for other views to work out *why* they need
redrawing, in case they only need to do a partial job. In a simple app, you
can leave them at their defaults.

Iain.
