Cool! I did try it.

Do you know off hand if it is MFC that forwards them to the parent or is it the system?

I dug a bit in MFC but didn't find where it was occurring - I didn't spend too much time on it Smile | :)

Just 'cuz I like to know these things! Smile | :)

I don't get that question. By stating "System", do you mean the OS? Can you please rephrase that? If you have to really dig this stuff out, check out "thrdcore.cpp".

Yes I meant the OS. Smile | :)

So, I looked again and found it right away LOL.

I had no idea PreTranslateMessage calls walked up the window heirarchy to the main window (not
that I ever came across a situation where it mattered until this discussion thread Smile | :)

).
Apparently it's for keyboard accelerator handling.

Ya learn something new everyday!

I wonder if this adds a danger to the misuse of PreTranslateMessage I see often on the message
boards...

Thank you so much!

PreTranslateMessage is one thing that is excessively misused. Smile | :)

Hi,

First,Thanks for your (very) quick reply. Big Grin | :-D

My problem is that I've overrided the PreTranslateMessage method,
and put a breakpoint in that function but I never get to that breakpoint.

However , when I move the focus to one of the controls(for example editbox),
the focused control gets the keyboard events... D'Oh! | :doh:

Is it possible that the controls receives keyboard events but the parent window does'nt????

Thanks again,
With best regards,
Eli

You may try this...
BOOL CXDlg::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class
if(pMsg->message==WM_KEYDOWN)
AfxMessageBox("ll");
return CDialog::PreTranslateMessage(pMsg);
}

Sorry but you need to read an article to do this not post here.. start with controlling input ports from lpt and learn about lpt addresses and low/high values

Do you need help responding to a button click, or displaying data?

Writing owner-draw control, CWnd or CStatic?

Moak1-May-07 15:11

Hi,

What is the difference in creating a CWnd derived or a CStatic derived owner-draw control (e.g. can I handle different messages, are there any limitations)?

I plan to rewrite some of my owner-draw controls (e.g. CStatic based image/text output). It seams for a CWnd based control the user needs to enter the exact class name in the resource editor, while with a CStatic based control the user can simply choose a static type in the resource editor. Thanks for feedback.

In sense of limitations - no difference.
With CWnd you need to do a bit more work, that is register a new window class. With CStatic there is no need in registration as it is already done and called STATIC [as I could remember it correctly].

It seams for a CWnd based control the user needs to enter the exact class name in the resource editor, while with a CStatic based control the user can simply choose a static type in the resource editor.

Yes it is so.

Thanks, seams I am going to be lazy and will design my owner-draw controls as CStatic derived classes.

you're probably not knowing that CStatic inherits from CWnd...
