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.

HELP!

When running this code on a SINGLE PROCESSOR machine I get a fairly accurate 100ms timer. When running on a DUAL PROCESSOR I see about a 110ms timer. In the app I am having trouble with I am requesting a 100ms timer but getting about 150ms!!! Does anyone know how to "fix" this issue?

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
);

How to use TTS_ALWAYSTIP with CToolBarCtrl?

11-Mar-04 5:30

Hello, I need to have the Tooltip displayed on the ToolBar even when its parent window is not active. I posted a message yesterday. I was told that I can set the TTS_ALWAYSTIP on the CToolTipsCtrl. But there is no CToolTipCtrl in my program
I am using the following code and don't know how to set the TTS_ALWAYSTIP.

BOOL CToolBarTipTestDialog::OnToolTipText(UINT, NMHDR* pNMHDR, LRESULT* pResult)
{
ASSERT(pNMHDR->code == TTN_NEEDTEXTA || pNMHDR->code == TTN_NEEDTEXTW);

// if there is a top level routing frame then let it handle the message
if (GetRoutingFrame() != NULL) return FALSE;

// to be thorough we will need to handle UNICODE versions of the message also !!
TOOLTIPTEXTA* pTTTA = (TOOLTIPTEXTA*)pNMHDR;
TOOLTIPTEXTW* pTTTW = (TOOLTIPTEXTW*)pNMHDR;
TCHAR szFullText[512];
CString strTipText;
UINT nID = pNMHDR->idFrom;

Please help me.
Thanks a lot in advance.

You've obviously got a CToolBar control being created somewhere (In your CMainFrame, or Dialog).
You can use:

CToolBar::GetToolBarCtrl
CToolBarCtrl& GetToolBarCtrl( ) const;

Return Value

A reference to a CToolBarCtrl object

Then:

CToolBarCtrl::GetToolTips
CToolTipCtrl* GetToolTips( ) const;

Return Value

A pointer to the CToolTipCtrl object associated with this toolbar or NULL if the toolbar has no associated tool tip control.

And Bob's your uncle.

Iain.

I still don't understand. Will you please give me more details.

There is not CTooltipCtrl in my project.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
