"copy example" button to the CHM

[AZJIO]

How to add a "copy example" button to the CHM reference file.

To get a list of files containing code samples, you need to search by <pre> tag.
1. Replace the <pre> tag with:

Code: Select all

<br /><a href="javascript:ClipBoard(pb);"><IMG title="Copy to Clipboard" style="margin: -16px 0px 0px 0px;" src="../copy.gif" border="0" align="right"></a>
<PRE class="codebox" id="pb">

2. Replace the </body></html> tag with

Code: Select all

<textarea ID="holdtext" STYLE="display:none;"></textarea><SCRIPT LANGUAGE="JavaScript">function ClipBoard(NumBlok){holdtext.innerText = NumBlok.innerText;Copied = holdtext.createTextRange();Copied.execCommand("Copy");}</SCRIPT>
</body></html>

3. We use the icon src="../copy.gif ", add it to the root folder. You can check in the browser how the button looks.
4. Compile the CHM help file and now it will have a copy code button without having to select the code text.

But not everything is as perfect as we would like. Some blocks listing constants also have a <pre> tag. If there is more than one tag, then the "pb" identifier must be different, for example pb1, pb2, pb3, etc.

Code: Select all

id="pb"
ClipBoard(pb)
