Use FindWindow()
You may be right
I may be crazy

You can use of
HWND hWnd = ::FindWindow("Notepad", NULL);
or CWnd *pWnd = ::FindWindow("Notepad",NULL);

Can anybody please tell me why the following code runtime errors at ar.close()?
CFile SaveColours;
SaveColours.Open("Colours.def",CFile::modeWrite);
CArchive ar(&SaveColours,CArchive::store);
int i=0;
while (i++<=20)
ar << i;
ar.Close();// <-----Runtime error as invalid file handle
SaveColours.Close();
Any references much appreciated.

Have you run this under the debugger? That's usually a good start. You can step into the CArchive::Close function and find out why it trips up.
You should also check that the Open for SaveColours worked properly.
(You might want to use CFile::modeCreate | CFile::modeWrite instead of just CFile::modeWrite, as well).
Chances are that because CArchive uses a buffer (around 4K) it isn't actually doing any I/O until you call Close, at which point it flushes (or tries to) to file.

Are you missing a share flag on your file open?
CFile SaveColours;
SaveColours.Open("Colours.def",CFile::modeWrite | CFile::shareDenyWrite);
CArchive ar(&SaveColours,CArchive::store);
int i=0;
while (i++<=20)
ar << i;
ar.Close();
SaveColours.Close();

Thanks guys,
It was the debugger that gave me the file handle was missing, from within filecore.cpp, that sent me on the goose chase.
Anyway new it would be something simple  "CFile::modeCreate" was the solution.
Much appreciated.

Yup. No substitute for looking at what's actually happening, rather than what you think is happening. I'm in the middle of writing a COM application to act as a specialised search engine (for my MP3 jukebox project, which will probably be my first CP article if I ever get it finished...).
For instance, by searching for 'BLUE SKY' tracks, like G**gle it should find the track titles containing both 'BLUE' and 'SKY'. Couldn't understand why the AND logic wasn't filtering out results. Looked very carefully at 'AND' code, seemed OK.
Then I spotted that when I got the results for 'SKY', there were far more entries than I expected - because I'd forgotten to clear the temp results after getting 'BLUE'. Doh!
At least I can blame it on my age...

Hi,
i need Help with Thread and Multiple-Views
I made already a MDIChildWnd Class that stores different Views.
Now i will change my project into a MultiThreadMDI.
The steps to made this are :
* Create the Frame
* In his Creation, create the Thread and pass the Frame m_hWnd
* In the Thread-Creation, create the View
So far so good. Before i change all my project, does anyone know if i can
still use MultiView ?
If i create another view, i must be also in a thread ...
So why not all the Frame into a Thread?
Anyone an idea?
BIG THANKS

You want a child window on a different UI thread than its parent?
Are you sure?
|
|
|
|

That's not really a good design. There are a lot of messages sent between parent and child windows, as part of the normal windowing system. When messages are sent between threads, it will block the sending thread and cause a context switch to the receiver, which nullifies the point of making the app multi-threaded.
|

|

Thanks, you two!
So i put only the View into a thread.
If i want to have a Frame with MultiView, i need to create each time a Thread with a View.
The Thread stores anyway the parent-Frame.
For each View i store the pointer of the view (which i get from a public Get-method of the Thread) in an array in the Frame and if i want to change
the view i make only a SetActiveView(array[selected]) ?
Big thanks !

I voted your posting a "1" for arrogance in the posting title. Why do you think your "[important]" post is any more important than all the other posts?
Apart from that little slip, it is an excellent post - the title (apart from "[important]" ) is descriptive, and the query describes your problem well.
I hope you received the help you were looking for.

Yes, but in a totally different way 
I use UserInterfaceThreads as WorkerThreads who keeps alive till i destroy'em

First I'll apologize if this is the wrong forum, but I didn't see anything DirectX specific.
I'm making an .X file viewer. Using a rather helpful tutorial on CodeProject I've been able to play my animations, and even make transitions from one animation to the other nice and smooth. All of this using the Animation Controller. I would like to play a given animation in reverse. However, DirectX's animation controller doesn't give you any sort of interface to the animations frames.
I'm fairly new to .X files (although I've been reading a lot) so any help you guys can give will be greatly appreciated.

Hi,
my problem is that I have a CDialog1(myClass1) in which I insert a propetysheet (using Picture Ctrl) in this propertysheet i add a propertyPage which generate me a CDialog2(myClass2).
I want to get variable from this CDialog and pass it to the first one because I'm sending thoses data into an access table.
I tried to get those parameters with this function
void CGeneralUser::GetParameter(CString& sStatus,CString& sgender,CString& stel,CString& smobile)
{
sStatus=m_status;
sgender=m_gender;
stel=m_tel;
smobile=m_mobile;
}
then I call this function in the first class(myClass1)
like this in boutton OK
CMyClass2 user;
user.GetParameter(sStatus1,sgender1,sTel1,smobile1);
When I write AfxMessageBox(sStatus1) for exemple the messagebox is empty I put UpdateData(TRUE); but it doesn't work
why???? thank's for your help

Please, use the code or pre tags when you post code !
zizzzz wrote: CMyClass2 user;
user.GetParameter(sStatus1,sgender1,sTel1,smobile1);
What you will do here is create a new instance of your CMyClass2 class and retrieve the parameters directly. So, for sure they are still to the default value because it is another class. You have to retrieve the data of your existing class, and not create a new class.
This has nothing to do with dialogs or property pages but with how you manages your classes.

ok I tried to retreive data from my existing class so I put
in MyClass1.h : CMyClass2 m_classe2;
and I call my parameter like this m_classe.status
i should proceed like that ? 
because i had errors when running the programm 
thank's

The docs state that if you are attempting to load a 16-bit DLL directly from 32-bit code, LoadLibrary() fails. I assume the same holds true for trying to load a 32-bit DLL directly from 64-bit code.
