Re: MFC: Easier way to know which Edit Control has the focus?

As a note, you could use:

CWnd *pFocus = GetFocus();
if (pFocus && pFocus->IsKindOf(RUNTIME_CLASS(CEdit)))
{
UINT id = pFocus->GetDlgCtrlID();
// makse use of the controls id here....

Maybe I'm missing something, but why can't you just GetFocus()? This will return a CWnd* of the window having the focus.

Hi all,

For example &File. If you press Alt + 'F' the file menu opens. ... I would like the underline to always display

Thanks all

Are you talking about the way Windows XP hides the underline until you press Alt?

If you are, this is a setting that you can change in the Display Properties (Control Panel -> Display or right-click on the desktop).

There you go to "Appearance", click on "Effects" and unselect the "Hide underlined letters for keyboard navigation until I press the Alt key".

I don't know how to change this from inside a program, but as it is a user's setting, you better keep it as the user choosed it to be.

The feature is not exclusive to Windows XP.

Check out the NoChangeKeyboardNavigationIndicators value in the following two registry keys:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

I didn't know... D'Oh! | :doh:

I still work with 2k but never noticed that "feature"... Blush | :O

Anyway, thanks for the info about the registry. Smile | :)

(although I still think that it is something not to be messed with, as it is an user setting) Unsure | :~

If you want to change it from inside a program, probably the best way to do it is like so:

BOOL a_bSet = TRUE;
SystemParametersInfo( SPI_SETKEYBOARDCUES, 0, (PVOID)&a_bSet, SPIF_SENDCHANGE );

Help in MFC intercept TCP Calls

Hi I want to manipulate the MFC classes to intercept TCP calls from normal applications like Internet Explorer or WS_FTP to 'connect' using the connect function in my socks client instead of the normal TCP call.
However, I am not sure what to use to implement this.
Can anyone tell me how to use MFC classes to do that?

Thanx!

Could someone please take the time and explain how to add tooltips to an existing mfc application?
I have an edit box that I would like to add tool tips to so the user knows exactly what needs to be input. I read something on msdn about it but for me msdn is not clear.
thanks for your help.

Presumably in response to an event like a click, you can call these to work out where the user is?
