Hello,
I would like to change the color of a static text (like a hyperlink) when I go with my mouse over the
text.
I already change the cursor to a hand-cursor when my mouse is over the static text.
Please let me know. 500 points
Best regards,
Thomas


BOOL COffenePostenDialog_Detail::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)

{

	BOOL bReturn;

	

	CRect rcBtn;

	CRect rcBtn1;

	CRect rcBtn2;

 

	CPoint ptCursor;

	CPoint ptCursor1;

	CPoint ptCursor2;

 

    // Calculate the current cursor position

	// Change cursor if we are over Internet and Email link

	//-----------------------------------

	CWnd* pBtn  = GetDlgItem(IDC_STATIC_INTERNET);

	CWnd* pBtn1 = GetDlgItem(IDC_STATIC_EMAIL);

	CWnd* pBtn2 = GetDlgItem(IDC_STATIC_TELEFON);

 

	pBtn->GetWindowRect(rcBtn);

    GetCursorPos(&ptCursor);

 

	pBtn1->GetWindowRect(rcBtn1);

	GetCursorPos(&ptCursor1);

 

	pBtn2->GetWindowRect(rcBtn2);

	GetCursorPos(&ptCursor1);

 

 

    //===========================================================================

	if(rcBtn.PtInRect(ptCursor)==TRUE ||rcBtn1.PtInRect(ptCursor1)==TRUE||rcBtn2.PtInRect(ptCursor1)==TRUE)

	{

		CWinApp* pApp = AfxGetApp();

		HCURSOR my_new_cursor = pApp->LoadCursor(IDC_CURSOR2); // load new cursor

		SetCursor(my_new_cursor);

		 bReturn = TRUE;

 

	}

   	else

	{

		bReturn = CDialog::OnSetCursor(pWnd, nHitTest, message);// default cursor

	}

	return bReturn;

   //===========================================================================

 

	return CDialog::OnSetCursor(pWnd, nHitTest, message);

}

 

 

 

 

 

HBRUSH COffenePostenDialog_Detail::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)

  {

	   HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

       //--------------------------- Link Color Internet/ Email ------------------------------

	  if((pWnd->GetDlgCtrlID()==IDC_STATIC_INTERNET) ||(pWnd->GetDlgCtrlID()==IDC_STATIC_EMAIL))

      {

		  pDC->SetTextColor(clr_blue); 		   

	  }

      //---------------------------------------------------------------------------------

  

 

 

 

	  return hbr;

  }

This is a nice sample (it is for a button, but you can apply the same concept to a static control):
http://www.codeproject.com/KB/buttons/hoverbutton.aspx

NOTE: may be you need to change CHoverButton::OnMouseHover from
void CHoverButton::OnMouseHover(WPARAM wparam, LPARAM lparam)
to
LRESULT CHoverButton::OnMouseHover(WPARAM wparam, LPARAM lparam)
and return 0 from it

Thomas, since you already are able to detect when the mouse is over your CStatic control here is some additional information and an approach I tested successfully:

1. Add a private BOOL variable to your CDialog derived class and name it "m_bMouseOver".

2. Associate control variables with your CStatic controls, you can do so by right-clicking on the static control and selecting "Add Variable" and name them e.g. "m_idc_internet" and "m_idc_email".

3. In your OnSetCursor method add the following code when you detect the on mouse over event in the if statement:

// Trigger a call to OnCtlColor
m_bMouseOver = TRUE;
m_idc_internet.Invalidate();
m_idc_email.Invalidate();

and in the else case, i.e. mouse out event:

m_bMouseOver = FALSE;
m_idc_internet.Invalidate();
m_idc_email.Invalidate();


4. Use the OnCtlColor code in the code snippet below.

Alternatively you could e.g. use the ColorStatic control from the project at http://www.codeproject.com/KB/static/coloredit_colorstatic.aspx as it provides a simple member method for changing the text color and might be easier to implement.
HBRUSH COffenePostenDialog_Detail::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)

{

	HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

	

	//------- Link Color Internet/ Email ------------------------------

	

	if(pWnd->GetDlgCtrlID() == IDC_STATIC_INTERNET || pWnd->GetDlgCtrlID() == IDC_STATIC_EMAIL) {

		if(m_bMouseOver == TRUE) {

			pDC->SetTextColor(RGB(0, 0, 255)); // Blue link color

		}

		else {

			pDC->SetTextColor(RGB(1, 1, 1)); // Black text color

		}

	}

      

	//---------------------------------------------------------------------------------

  

	return hbr;

}
