Hi,
I want to open only one set/window (doc + ChildFrame + view) on pressing menu button which replaces OnFileNew().
If the button is pressed again the window shoud be brought forward if it was unactive.
I found CDocTemplate::GetNextDoc() function which stores documents (CDocument*) created for any particular template. If GetFirstDocPosition() gives NULL no document was instantiated therefore no window displayed, so the button should create/displayed this window. Otherwise activate the already existing one. Is my understanding correct or maybe there are more elegant solutions?
siema.

so you want only one document to be open in an MDI application?
if a document is open you want it to be "activated", otherwise create a new one?

only one document of any kind.
For example have 4 buttons each for creating diffrent document.
On press any of these buttons I want document to be created if not created already or "activated" if created.
Back to my original question, is there any well known solution to that "problem"

Are you doing Serial communications?
If so, This is ERROR_IO_PENDING and is NO ERROR!!
It just means that WaitCommEvent or ReadFile is busy reading characters but the function returns to let you do some other stuff untill its ready. Or something like that.
Search MSDN Online for "Serial Communications in Win32". This helped me a lot.

That's really hard to tell without knowing the surrounding code.

Hi,
I am relatively new in MDI database development (3 weeks) although seasoned C++ campaigner. Could you please advice me about advanced (the basic staff I have) textbooks regarding MDI (Multi. Doc. Inter.) development.

Any of the basic Win32 API Books such as Petzold cover MDI. I don't know how Database and MDI fit together though. You are better off to focus on the Document - VIew architecture. MDI/SDI are simply different ways of using that.

Hi,
I needed to do some compare works with two DVD-ROMs --- the one is a local
dvdrom and the other is a remote dvdrom. My question is how to find/get
the remote dvdrom by using aspi scsi command and some proper internet settings?
Would you please points me some useful materials ?
Thanks in advance!

You can't. ASPI is inherently locked to the HA on the hardware (machine) your program is running on.

Hello there,
Does Microsoft stop MFC supporting in VC++ .NET ??
Is it right ?

It is supported, but be warned it is not backward compatible. It is very likely a VC++6.0 dsw/dsp project does not recompile with 0 error.
Though most errors can be easily handled, some of them turn out to be much tougher in practice, because the STL code (templates everywhere) is behind all MFC code now.
Recompiling the code requires updating stuff either from MFC classes, or ATL classes.
Distribution also changes. Now it is MFC70.DLL, MSVCRT70.DLL, ... (in fact you have a merge module in the VS.NET cd).
Good luck!
If you have spare time, an article about tips for the upgrade would be welcome!![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Hello there ...
What's wrong in below code ?
void CTestthreadDlg::OnStart()
{
DWORD dwThreadID, dwThreadParam = 1;
hThread = ::CreateThread( NULL, 0, ThreadFunc, &dwThreadParam, 0, &dwThreadID );
}
DWORD WINAPI CTestthreadDlg::ThreadFunc(LPVOID lpParam)
{
m_List.AddString( "I wanna die, die for you ... Cause i know you are my only one" ); // 
return 0;
}
Compiler show me this error:
E:\Microsoft Visual Studio\MyProjects\testthread\testthreadDlg.cpp(102) : error C2664: 'CreateThread' : cannot convert parameter 3 from 'unsigned long (void *)' to 'unsigned long (__stdcall *)(void *)'
None of the functions with this name in scope match the target type

Well, now my source code works fine by declaring ThreadFunc as global !
Cup, can you show me how declare ThreadFunc as static function ?

Hmmmm! No one's ever called me "cup" before
Anyway making a member function static is easy. Just add static to the function declaration.
For example :-
static int GetTotal();

I think the method ThreadFunc should be declared as static.
Or you can use an ordinary function, not a method. This, i think, is the best choice because it always keeps you away from the attempt of using static/non static members in a static method.

If I recall correct you have to declare your ThreadFunc static if you want it to be a member function. Or you can declare it global.
In cpp file
DWORD WINAPI ThreadFunc(LPVOID lpParam);
<br />
DWORD WINAPI ThreadFunc(LPVOID lpParam)<br />
{<br />
DoStuff();<br />
}<br />
<br />
