What other files are being #included in stdafx.h?

Only the windows.h and the winuser.h

Have you defined _WIN32_WINNT? If not, look at line #5040 of winuser.h.

Hi CPians!
I have a MFC Dlg app, that should be able to fire up an unlimited amount of dialogs when clicking on one button (e.g. one dialog per click). In the OnClickButton handler, if i run my code that way :
CMyDialog mydlg;
mydlg.DoModal();
the main dialog freezes after the first child dialog is started (of course, that's the way modal dialog are meant to work).
If I do it this way :
CMyDialog mydlg;
mydlg.Create(...);
mydlg.Show();
the dialog is closed as soon as I leave the OnClickButton, that is almost instantly, since mydlg is a local variable in that function.
So what I intend to do is launch the dialog modal in a working thread, but this semms to be a bit paradoxical to me. Is it any better solution, or is this the ultimate one ?
Thanks a lot

why don't you declare CMyDialog as member variable or global variable or static variable, that will work exactly as you intend.

Because I do not know how many of them I will need (see in my post, you fire up a dlg every time you click on a button). So declaring them as global would require a dynamical global array of dlgs

You may use:
CMyDialog *pmydlg=new CMyDialog;
pmydlg->Create(...);
pmydlg->Show();
to create the modeless dialog who's PostNcDestroy should look like this:
void CMyDialog::PostNcDestroy()
{
CDialog::PostNcDestroy();
delete this;
}

Thanks rechi, I had already thought about something like this, i missed the existence of PostNcDestroy. Thanks again.

in your button event,you should like this:
CMyDialog mydlg=new CMyDialog;
mydlg.Create(...);
mydlg.Show();
in the class of CMyDialog
you should add a function
CMyDialog::PostNCDestroy()
{
delete this;
}

Yep, even better with a pointer (see rechi's post) IMO. Thanks a lot for your help.

- mciSendString("set capture samplespersec 11025", 0, 0, 0);<br />
- mciSendString("set capture channels 2", 0, 0, 0);<br />
- mciSendString("record capture",0,0,0);<br />
- mciSendString("save capture c:\\test.mp3",0,0,0);<br />
when test.mp3 file saved, I play it with windowmedia and one error occur "ClassFactory cannot supply requested class (Error=80040111)"
somebody can help me to fix it, thanks

HI;
Which headfile is include the GetLastInputInfo function ?

How did you find out the function exists ? If from the MSDN, it tells you what header to include.

The function is exits , so
you can find it with input "::" in C++
d
|
|
|
|
|
so you've already included it. :: won't show you every function that exists, across header files that the compiler isn't able to look at, how could it ?
msdn.microsoft.com. I know the answer, but it would serve you better to work out how to find it for yourself, it's not hard. Google would almost certainly link to the MSDN entry.

What I'm trying to do this time is talk to a USB device. I'm not sure what port I need to acess to be able to talk to it. Or if I need to check what port it's on before I talk to it. I do hate to bother but I do have another question. How would I write a program that is a system process(doesn't have to be run by the sys just so there are no visuals to it and is only a process)?Thank you for your time.

To write a process with no interface in VC++, write all ur code inside WinMain() and dont create or draw any windows. Ur program will run hidden. U can check that ur appl. is running by doing Ctrl+Alt+Tab.
lol, i dont know any other better way
Remember... testing & debugging are always part of programming ...so exterminate those stinking bugs

i wanted to learn assembly but can't find the compiler for it... i hope it's free... does it come with vc++6 studio and if so were?

Hello,
I've got a dialog application generated with the Visual Studio 6 class wizard. After generating the app, I added an acellerator table.
I loaded the table like this
::LoadAcelerators(AfxGetApp()->m_hInstance, MAKEINTRESOURCE(IDR_MAINFRAME));
I tried loading it at several places, in the InitInstance() and the main dialog constructor for exemple.
I don't know why, but my shortcut keys don't seem to work  .
Did someone experience the same problem, or does anyone know an answer to this %$&^%N problem? Thanks in advance.

::LoadAcelerators
is this api valid, could not find it in the MSDN.
give this method a try
LoadAccelTable(...)
it needs to be loaded in the framewindow.
