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 ImageSize property defines the size (width/height) of the icons within the control's Images collection.

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.
• <img>key[:width]</img> inserts a custom size picture being loaded using the HTMLPicture property. The Key parameter indicates the key of the picture being displayed. The Width parameter indicates a custom size, if you require to stretch the picture, else the original size of the picture is used.
• <font face;size>text </font> displays portions of text with a different font and/or different size. For instance, the <font Tahoma;12>bit</font> draws the bit text using the Tahoma font, on size 12 pt. If the name of the font is missing, and instead size is present, the current font is used with a different size. For instance, <font ;12>bit</font> displays the bit text using the current font, but with a different size.

Also, newer HTML format supports decorative text like follows:

• <gra rrggbb;mode;blend> ... </gra> defines a gradient text. The text color or <fgcolor> defines the starting gradient color, while the rr/gg/bb represents the red/green/blue values of the ending color, 808080 if missing as gray. The mode is a value between 0 and 4, 1 if missing, and blend could be 0 or 1, 0 if missing. The <font> HTML tag can be used to define the height of the font. Any of the rrggbb, mode or blend field may not be specified. The <gra> with no fields, shows a vertical gradient color from the current text color to gray (808080). For instance the "<font ;18><gra FFFFFF;1;1>gradient-center</gra></font>" generates the following picture:

  

• <out rrggbb;width> ... </out> shows the text with outlined characters, where rr/gg/bb represents the red/green/blue values of the outline color, 808080 if missing as gray, width indicates the size of the outline, 1 if missing. The text color or <fgcolor> defines the color to show the inside text. The <font> HTML tag can be used to define the height of the font. For instance the "<font ;31><out 000000><fgcolor=FFFFFF>outlined</fgcolor></out></font>" generates the following picture:

  

• <sha rrggbb;width;offset> ... </sha> define a text with a shadow, where rr/gg/bb represents the red/green/blue values of the shadow color, 808080 if missing as gray, width indicates the size of shadow, 4 if missing, and offset indicates the offset from the origin to display the text's shadow, 2 if missing. The text color or <fgcolor> defines the color to show the inside text. The <font> HTML tag can be used to define the height of the font.  For instance the "<font ;31><sha>shadow</sha></font>" generates the following picture:

  

  or  "<font ;31><sha 404040;5;0><fgcolor=FFFFFF>outline anti-aliasing</fgcolor></sha></font>" gets:

  

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

Private Sub Slider1_Change()
    With Slider1
        .Caption(exThumbPart) = .Value
    End With
End Sub

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

void OnChangeSlider1() 
{
	CString strFormat;
	strFormat.Format( _T("%i"), m_slider.GetValue() );
	m_slider.SetCaption( 256, strFormat );
}

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

With AxSlider1
    .set_Caption(EXSLIDERLib.PartEnum.exThumbPart, .Value.ToString())
End With

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

private void axSlider1_Change(object sender, EventArgs e)
{
    axSlider1.set_Caption(EXSLIDERLib.PartEnum.exThumbPart, axSlider1.Value.ToString());
}

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

*** ActiveX Control Event ***

with thisform.Slider1
	.Caption(256) = .Value
endwith
