Huh? A crash should never be expected, especially if a window receives a message that it does not handle. If a window receives a message that it does not handle, DefWindowProc() or DefDlgProc() just sends it on.

Not recommended. While older books and tutorials used WM_USER, these symbols caused problems by conflicting with messages that Microsoft was using. Use WM_APP instead.

how could i exchange data between the TreeView and Dialog(not FormView)??

I presume some method in the tree view class is in charge of displaying the dialog. Correct? If so, then you'll want something like:

void CMyTreeView::OnButtonClick()
{
    CMyDialog dlg;
    if (dlg.DoModal() == IDOK)
    {
        // access member variables of <code>dlg</code> object here
    }
}

Make sense?

I guess I'll have to go back and change all of my working code to longer work. I've done it so many times, it might take a while, but if you say there is no solution, well...

I thought the code snippet I provided was sufficient. As it is apparently not, please show the code you are using when the button is clicked to display the dialog box.

All I asked for was one function. How big can that be?

Why did you save the file as Roshal Archive (RAR) instead of something more common (e.g., ZIP), or uncompressed since it is just a text file?

Aplication crashes

I have a serious problem. I hv a VC application which has a feature to write to a DVD, which we have implemented as a DLL which inturn uses another DLL(which has been bought).

from my aplication i open a dialog(which is part of the dll) which takes in the parameters required for burning.
Initialy i click on the build button of the dialog.It shows the progress bar,but as the progressbar is on if i cancel the dialog then the application crashes.
once the progress is completed and then i cancel then the appllication does not crash

if anybody can think for a solution on this then plz let me know

Well, you don't give us a lot of information to work with, but using common sense, the most logical place to look for your problem is in your OnCancel handler of the process dialog.

One other guess is that you have a background thread running for the DVD processing. When you click cancel, you are leaving your dialog too soon - the background thread is still running, but you have deleted some data it requires. It tries to access the data and gets an access violation fault.

I think that you'll have to subclass CFileDialog to handle these things.

How to open default mail client and pass to it subject, body and an attachement?

petehero27-Jul-05 19:01

27-Jul-05 19:01

This is a way:
ShellExecute(pMainFrm->m_hWnd,"open",
"mailto:@?body="+mailBody,NULL,NULL,SW_SHOW);

But the body has 2048 bytes limit;
and it can't have an attachement.

Is there another way to solve it?
Or break through the limit of 2048 bytes?

Opening the default mail client is necessary.

Thanks!!

Thanks for reply.
I tried:
mailto:joe@something.com?subject=Test&attachment="c:\boot.ini"

But it doesn't work.

thanks for reminding me,
I will create a *.eml file instead.

And this is a good idea:
ShellExecute(NULL,"open", "test.eml","","",SW_SHOWNORMAL);

Thanks a lot,
Peter

Then outlook express opens a new email window with subject "Test".

But there is no attachment.

thanks

Setting first to NULL is a matter of good style, nothing will ever detect that you did, or complain that you didn't ( which is sort of the point ). When you create it, it's too late, before you create it, you want it to be NULL so you can tell it has not been created. So, all pointers should be set to NULL in the constructer for members, and at the time they are declared for variables in functions. There would be no point in setting it to NULL jsut before it got given a valid value.
