Note: Strings that include byte sequences of 13,10 (0D,0Ah) known as CRLF or 10 (0Ah) known as LF, ARE IGNORED. Use the <br> or <p> if you wish to break to a new line.
<a> tag supports internal ids if prefixed with a #, for example:
Click on this <a href="#1010">link</a> to show a message box
The url title text is shown as 'link' and the id as #1010. When the url is clicked, the id will be converted to an integer (1010) and send to the parent window via the WM_COMMAND message with the id integer stored in the high word of wParam
DrawBBCODE:
The DrawBBCODE function supports the following bbcode tags, enclosed in square brackets [] for starting tags and [/] for ending tags:
[b] [/b],<strong> </strong>for bolding text[i] [/i]for italic text[u] [/u]for underlined text[code] [/code]for preformatted text[color=#RRGGBB] [/color]for color of text using a hex string[q] [/q],[quote] [/quote]for block quotes*[ul] [/ul]for unordered lists with bullets[ol] [/ol]for ordered lists with numbers[li] [/li]or[*]for list items within a list[url] [/url]for hyperlinks having a url and title
*Experimental/Not Complete
Note: There is no bbcode for line breaks or paragraph. Strings that include byte sequences of 13,10 (0D,0Ah) known as CRLF or 10 (0Ah) known as LF, are automatically processed to break to a new line.
[url] tag supports internal ids if prefixed with a #, for example:
Click on this [url=#1010]link[/url] to show a message box
The url title text is shown as 'link' and the id as #1010. When the url is clicked, the id will be converted to an integer (1010) and send to the parent window via the WM_COMMAND message with the id integer stored in the high word of wParam
A RadASM example project is included to demonstrate the DrawHTMLCODE function. It can be found in the releases folder, or can be downloaded directly from here.
