Running a new ActiveX Control help.

Hi, this is my first time ever using ActiveX (so please bare with me) and I'm having trouble getting a control to work. I'm trying to use the control ScintillaVB (it can be found here http://www.ceditmx.com/scivb/index.asp[^] ) on a VC++ 2005 project (I'm also running Vistax64, maybe that's a factor), but when I place the .ocx on the form and run it, nothing shows up on the new window. I've followed all the directions given on the site, but maybe I don't understand using ActiveX controls well enough. Could someone please take a look at this, or give me a little help on the steps for setting up a ActiveX control in VC++ 2005 ? Thank you!

If you have an already Registered ActiveX Control, you may use to the "Microsoft Visual C++ ActiveX Test Container" i suggest to you as by secondary step.

Please provide a link to the documentation you read that told you to use AfxEndThread(...) in the way you are using it.

void AFXAPI AfxEndThread(UINT nExitCode, BOOL bDelete = TRUE); in afxwin.h

this is what am getting when right click on AfxEndThread and goes for its definition

So you think the declaration in the header file is the documentation? No it is not.

Check this out[^]

And follow the linked content that says:

For more information on AfxEndThread, see the article Multithreading: Terminating Threads.

If you want to be a software developer you are going to have to read more than header files. Wink | ;)

If CMStudentDlg isn't the main dialog, why are you casting a pointer to the main dialog to (CMStudentDlg *)?

I'm not sure where to begin. The secondary threads should not communicate with the UI components owned by the primary thread. If the secondary threads need to update a UI component, they should do so by posting a message to the primary thread.

how will i call the objects (from the dialog which i have created) inside a thread declared in created dialog ?

in the main dialog i have used -- CMainDlg *dialog=(CMainDlg*)AfxGetApp()->GetMainWnd();

and for getting an object of listbox (dialog->m_list where m_list is member variable of list box in maindialog) in the thread which i have been using.

Create win32 modal child window

Call RegisterWindowMessage() to define a new window message (that is guaranteed to be unique throughout the system). In the secondary thread, post that message. In the primary thread, respond to that message like:

ON_REGISTERED_MESSAGE(USER_WINDOWS_MESSAGE, OnMyMessage);
...
LRESULT CMyDialog::OnMyMessage(WPARAM, LPARAM lParam)
{
    // do something like update a listbox or a progress control
    return 0;
}

"Best" meaning "New and improved"? Or the "Best" because it has a 30 day money back guarantee?

"Lean and mean" code as in development/maintenance overhead or runtime performance? Never mind I have lost interest now since it has taken you at a minimum three posts to explain your request.

Really you consider your original post to be "specific"? In that case you might want to consider this[^].
