How can i change the color of text in textbox?

How can i change the color of text in textbox?
Such as the color of first line text is red,and the second line is blue?
I can use API GetDC/SetTextColor/TextOut in VB to implement, how can I do the same thing in Basic4PPC?

Tks.

The TextBox control can only display text with a single color.
For example:

These API calls will not help as the underlying control doesn't support more than one color.
You will need to use agraham's Web browser control: http://www.b4x.com/forum/additional-libraries/1862-web-browser-desktop-device.html
Or dzt'z HTMLView library: http://www.b4x.com/forum/additional-libraries/782-htmlview-library.html
