How to start?

The following steps show you progressively how to start programming the Exontrol's ExToolTip component: 

• In VB
  • Add a reference to the ExToolTip 1.0 Control Library, using the Project\Reference
  • Add declaration for the component, like Private WithEvents t As EXTOOLTIPLib.ToolTip, if you plan to use the events of the control, else you can use Dim t as New EXTOOLTIPLib.ToolTip, to instantiate the control 
  • Instantiate the component when the form is loading, as follows: Set t = New EXTOOLTIPLib.Top, and so your form may use the newly created tooltip 
  • Specify the tooltip's appearance, icons or pictures using common properties like: Appearance, Images, HTMLPicture and so on
  • Call the ShowToolTip method when the mouse is moving.

    Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
        t.ShowToolTip "This is a bit of text that's shown when the cursor hovers the form"
    End Sub

• In VB.NET
  • Add a reference to the ExToolTip 1.0 Control Library, using the Project\Add Reference\COM
  • Add declaration for the component, like Private WithEvents t As EXTOOLTIPLib.ToolTip, if you plan to use the events of the control, else you can use Dim t as New EXTOOLTIPLib.ToolTip, to instantiate the control
  • Instantiate the component when the form is loading, as follows: Set t = New EXTOOLTIPLib.Top, and so your form may use the newly created tooltip 
  • Specify the tooltip's appearance, icons or pictures using common properties like: Appearance, Images, HTMLPicture and so on
  • Call the ShowToolTip method when the mouse is moving.

    Private Sub Form1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove
        t.ShowToolTip("This is a bit of text that's shown when the cursor hovers the form")
    End Sub

• In C#
  • Add a reference to the ExToolTip 1.0 Control Library, using the Project\Add Reference\COM
  • Instantiate the component when the form is loading, as follows: t = new EXTOOLTIPLib.ToolTip(), and so your form may use the newly created tooltip
  • Add the handler for the AnchorClick event, in case you plan to use it as follows:

    t.AnchorClick += new EXTOOLTIPLib._IToolTipEvents_AnchorClickEventHandler(t_AnchorClick);

    void t_AnchorClick(string AnchorID, string Options)
    {
        System.Diagnostics.Debug.WriteLine("AnchorClick event");
    }

  • Specify the tooltip's appearance, icons or pictures using common properties like: Appearance, Images, HTMLPicture and so on
  • Call the ShowToolTip method when the mouse is moving.

    private void Form1_MouseMove(object sender, MouseEventArgs e)
    {
        t.ShowToolTip("This is a bit of text that's shown when the cursor hovers the form", "", "", "", "" );
    }

• In C++
  • Import the Exontrol's ExToolTip type library using the #import "c:/winnt/system32/extooltip.dll", so the EXTOOLTIPLib namespace is defined
  • Add a member of EXTOOLTIPLib::IToolTipPtr type to your dialog, as EXTOOLTIPLib::IToolTipPtr m_spToolTip
  • Instantiate the m_spToolTip member as follows:

    CoInitialize( NULL );
    if ( SUCCEEDED( CoCreateInstance( __uuidof(EXTOOLTIPLib::ToolTip), NULL, CLSCTX_ALL, __uuidof(EXTOOLTIPLib::IToolTip), (LPVOID*)&m_spToolTip ) ) )
    {
    }

  • Use the Notifier property to assign the handle of the dialog that receives notifications from the tooltip, if we plan to use the control's events.
  • Specify the tooltip's appearance, icons or pictures using common properties like: Appearance, Images, HTMLPicture and so on
  • Handle the WM_MOUSEMOVE message of the dialog, or add a handler to the PreTranslateMessage function to call the ShowToolTip method:

    BOOL PreTranslateMessage(MSG* pMsg) 
    {
    	/* 
    		Handles the WM_MOUSEMOVE message during the PreTranslateMessage so it can show the tooltip even if we move the mouse over the inside controls too. 
    		As the WM_MOUSEMOVE message is not sent to dialog, if the cursor hovers the inside windows...
    	*/
    	if ( pMsg->message == WM_MOUSEMOVE )
    	{
    		if ( m_spToolTip != NULL )
    			m_spToolTip->ShowToolTip( COleVariant( "This is a bit of text that's shown when the cursor hovers the form" ), vtMissing, vtMissing, vtMissing );
    	}
    	return CDialog::PreTranslateMessage(pMsg);
    }

• In VFP
  • Create the Exontrol's ExToolTip object as follows:

    public t as Object
    t = CreateObject("Exontrol.ToolTip")

  • Specify the tooltip's appearance, icons or pictures using common properties like: Appearance, Images, HTMLPicture and so on
  • Call the ShowToolTip method during the Form's MouseMove event as follows:

    LPARAMETERS nButton, nShift, nXCoord, nYCoord
    
    with t
        .ShowToolTip("This is a bit of text that's shown when the cursor hovers the form")
    endwith

• Web
  • Add a member to the page, as Dim t
  • Use the window_onload event to create the Exontrol's ExToolTip object as follows:

    Sub window_onload
    	set t = CreateObject("Exontrol.ToolTip")
    End Sub

  • Specify the tooltip's appearance, icons or pictures using common properties like: Appearance, Images, HTMLPicture and so on
  • Call the ShowToolTip method during the document_onmousemove event as follows:

    Sub document_onmousemove
    	t.ShowToolTip "This is a bit of text that's shown when the cursor hovers the form"
    End Sub
