WM_CHAR revisited

[Neil Hosgood]

Hiya all.

I need to trap the ENTER key from any control on a dialog, I have
just searched for WM_CHAR in the forums and found a few ideas
but I am confused. It appears the most common reply is to
sub class a control.
The follwoing is from the win32 help file..

The WM_CHAR message is posted to the window with the keyboard
focus when a WM_KEYDOWN message is translated by the
TranslateMessage function. WM_CHAR contains the character code
of the key that was pressed.

This leads me to believe that that I should be able to
trap the WM_CHAR message in the dialogs callback with something
like

Select Case CBMSG
Case %WM_CHAR
If CBWPARAM = %VK_RETURN Then
SendMessage hDlg, %WM_CHAR,%VK_TAB,0
Function = 0 'stop the enter key going further
End IF
End Select

It was this easy in VB3, am I doing something wrong in PB. ?
I shouldnt have to subclass just to trap a key.

Please Help.
NJH.

Neil --
PB uses Windows's dialog engine.
By default, the system handles all keyboard input to the control and interprets certain types of keyboard input as dialog box navigation keys (enter, tab and so on).
It's enough comfortable for most situations.

If you want to override default behavior, you can:
a) To use Dialog Show Modeless and to write own message loop (w/o IsDialogMessage) - very easy and comfortable
b) To process WM_GETDLGCODE message, which is sent to the window procedure associated with a control.
c) To subclass controls.

Semen,

Thanx for your reply (been away for a while).
Have got it working by trapping it in messge pump, will have
a look at subclassing though
Speaking of which, I was just playing with your ddt dialog
scrolling code; kewl! Just gotta work out how to make it scroll
as a child window (or dialog).
