Use the Caption property to specify a caption on any part of the control. Use the Font property to specify the control's font. Use the ForeColor property to specify the caption's color, if the <fgcolor> tag is not used. Use the Value property to specify the control's value. The CaptionAlignment property specifies the alignment of the caption in the part area. Use the CaptionIndentX property to indent the caption on the part, on the X axis. Use the CaptionIndentY property to indent the caption of the part on the Y axis. Use the Background property to change the visual appearance for any part of the control, in any state.

The Caption property supports the following built-in HTML tags:

• <b>  bold </b> bolds a part of the caption.
• <u> underline </u> specifies that the portion should appear as underlined. 
• <s> strikeout </s> specifies that the portion should appear as strikeout. 
• <i> italic </i> specifies that the portion should appear as italic. 
• <fgcolor=FF0000>fgcolor</fgcolor> changes the foreground color for a portion.
• <bgcolor=FF0000>bgcolor</bgcolor> changes the background color for a portion.
• <br> breaks a line.
• <solidline> draws a solid line. If has no effect for a single line caption.
• <dotline> draws a dotted line. If has no effect for a single line caption.
• <upline> draws the line to the top of the text line
• <r> aligns the rest of the text line to the right side. It has no effect if the caption contains a single line.
• <img>number[:width]</img> inserts an icon inside the cell's caption. The number indicates the index of the icon being inserted. The width is optional and indicates the width of the icon being inserted. Using the width option you can overwrite multiple icons getting a nice effect. By default, if the width field is missing, the width is 18 pixels.

For instance, the following VB sample prints the control's Value on the control's thumb:

Private Sub ScrollBar1_Change()
    With ScrollBar1
        .Caption(exThumbPart) = .Value
    End With
End Sub

The following C++ sample prints the control's Value on the control's thumb:

void OnChangeScrollbar1() 
{
	CString strFormat;
	strFormat.Format( _T("%i"), m_scrollbar.GetValue() );
	m_scrollbar.SetCaption( 256, strFormat );
}

The following VB.NET sample prints the control's Value on the control's thumb:

With AxScrollBar1
    .set_Caption(EXSCROLLBARLib.PartEnum.exThumbPart, .Value.ToString())
End With

The following C# sample prints the control's Value on the control's thumb:

private void axScrollBar1_Change(object sender, EventArgs e)
{
    axScrollBar1.set_Caption(EXSCROLLBARLib.PartEnum.exThumbPart, axScrollBar1.Value.ToString());
}

The following VFP sample prints the control's Value on the control's thumb:

*** ActiveX Control Event ***
