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!

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?

In MFC...

CWinApp::LoadIcon 
HICON LoadIcon( LPCTSTR lpszResourceName ) const;

HICON LoadIcon( UINT nIDResource ) const;

In Win32:

The LoadImage function loads an icon, cursor, animated cursor, or bitmap.

HANDLE LoadImage(
  HINSTANCE hinst,   // handle to instance
  LPCTSTR lpszName,  // image to load
  UINT uType,        // image type
  int cxDesired,     // desired width
  int cyDesired,     // desired height
  UINT fuLoad        // load options
);
