Wait a second. Would it make more sense to have the .DLL increment a variable local to IT every time a key is pressed and the hook is called, and then export a function to return (and then reset) this value, so the main program can just call this func when it wants to, rather than the .DLL telling the program when it feels like it?

There are a number of ways of letting a program know that something happened. They vary in complexity and flexibility. Some of them are:
- callback functions
- posting a custom message to a window
- posting WM_COPYDATA to send data + notification
Hope this helps and that I'm not stating the obvious.

Hey thanks for that! That's what I love about this site - you constantly pick up little scraps of information that will prove useful.

Posting (PostMessage) a WM_COPYDATA message is NOT recommended.
Use SendMessage or SendMessageTimeout instead.

Gert is absolutely right. Use SendMessage() instead of PostMessage() when delivering WM_COPYDATA. My mistake!

I guess you could give the dll an interface to the main program. Just a pointer to an instance of some class with some functions to process input from the dll. This is the way 3d Studio VIZ handles plugins.

I've done it a different way (but thanks to all who answered). When I call the Init function in the .DLL I pass the handle of the window of my prog. Then the key function just sends a message to the main program that a key was just pressed. I use ::PostMessage(), and if I lose a key every now and then, it won't be missed among the million-or-so other keys a month I type.
I can't wait to actually get this project going because I want to start letting the world know about it!

I'm trying to look for some tuts or sample apps that use radio buttons. Ihave 2 radio buttons on my dialog, and need to disable certain controls when one or the other is selected, depending on what is selected.
If anyone knows of any good sites that may have what I'm looking for or if anyone could provide insight or maybe a quick sample about what I'm trying to do, I would really Appreciate it.
Thanks so much in advance.

Go to the resource editor, and make sure you have the wizard bar visible. Click on a radio button and the drop down will let you add an OnClick handler for that button, which you can then use to enable/disable items to your hearts content.

OK, I suppose I'm looking for an API function or MFC function that is actually responsible for disabling controls?

Well, you didn't say you needed to know *that* part as well. 
Every CWnd derived class has a method called EnableWindow, which takes a BOOL.

OK, you'll have to pardon my lack of knowledge but doesn't EnableWindow() actually enable/disable the entire window? Where as I'm looking to enable/disable only a specific control in the window. Unknowingly i did:
void CPro1WinTUSDlg::OnMainDataRadio()
{
EnableWindow(IDC_EDIT1==TRUE); // or FALSE
}
As you know, whis doesn't produce the correct results. It actually disables my entire program, or at least locks it up (heh).
Sooooo, am I doing something wrong or do I need to use a different function?
Thanks!!!

Yes, you want to disable the control, which is also CWnd derived. So you need to create variables that map to your controls and then call EnableWindow on them.

Do this:-
GetDlgItem (IDC_EDIT1)->EnableWindow(FALSE)

I tend not to use GetDlgItem, but you're right, given the method you want is in the base class, it's as good a way of doing it.

Yeah, true. After raeding a couple of articles by Joe Newcomer I have always tried to avoid GetDlgItem and UpdateData in my code, specially being a big fan of Joe, that I am.
A lot of people seem to forget that we can use class wizard to create control variables for our dialog controls. I mean most people would have associated CStrings with text boxes but how many associate an edit box with a CEdit?

It was Paul DeLascia who pointed it out to me, in an MSJ article.

I almost *always* associate with a control, not a variable. Then I can roll my own data validation, which is always better than the rubbish MFC comes out with.

I use GetDlgItem and UpdateData all over my code for too many years. I haven't read Joe's writings on why they're bad. Can you briefly tell me the problem?
I guess it's habit - it's how I was shown a long time ago. It appears to work well though. Is it considered bad style now?
thx

Hi Guys,
i am creating an app with a doc/view architecture. The base class of my view class is CListView. Now i am using the InsertColumn function of CListCtrl. After that i am inserting some strings with the InsertItem function. The problem now us that i am changing the font, and the font of the Column also changes. WHY ?? I want that the Column Font stay always same and only the inserted String font wwould be changed...
Please see code:
void CFVCtrlView::OnInitialUpdate()
{
CListView::OnInitialUpdate();
CListCtrl &lCtrl=GetListCtrl();
lCtrl.InsertColumn(0,"Header",LVCFMT_LEFT,300);
lCtrl.ModifyStyle(0, LVS_SORTASCENDING | LVS_REPORT | LVS_EX_FULLROWSELECT );
lCtrl.SetBkColor(RGB(160, 184, 207));
}
.
.
.
void CFVCtrlView::SetFonts()
{
CListCtrl &lCtrl=GetListCtrl();
CFont *font=(CFont *)this;
font->CreatePointFont(100,"arial");
lCtrl.SetFont(font);
lCtrl.InsertItem(1,"Hello World",0);
}
Please help if anybody can...
Its really urgent.
regards
sonu

It's really obvious when you think about it - you've set the font for the list control, so the list control uses that font.
I don't know of any way to fix this apart from making the list owner drawn and storing a font, or font details, for each cell that doesn't use the standard font of the control as a whole. That doesn't mean there *isn't* another way, I've never tried to do what you're doing.
Chris's grid control in a form view may provide the answer, I'm not sure if it does per cell fonts or not.

How can I change the title caption of a dialog (CDialog) object?
I want to do the following:
CSetupDlg::OnShowSummary()
{
CString sMyTitle;
CSummaryDlg dlg;
// Somehow, set the title of the Summary Dialog
// with sMyTitle, today's date, or "The Summary is..."
dlg.doModal(); // I might use modeless case - must work both ways.
}
Thanks all!
Happy Holidays (BTW, http://www.crackermatic.com was funny )
