Syntax

<Result> = PDFReaderHighlight(<PDF Reader control> , <Sought text> [, <Color> [, <Search options>]])

<Result>: Integer

Number of text occurrences found in the control.
0 if no element contains the sought text.

<PDF Reader control>: Control name

Name of PDF Reader control to use.

<Sought text>: Character string (with quotes)

Text that must be found in the specified element.
"" (empty string) to cancel the search.

<Color>: Integer, constant or optional Color variable

Color used to highlight the occurrences found. This color can correspond to:
an RGB color (returned by RGB),
an HSL color (returned by HSL),
a preset color of WLanguage.
a Color variable.
Remark: The color used by default is light yellow.

<Search options>: Optional Integer constant

Indicates the search options:
WholeWord Search for a whole word (enclosed in punctuation characters or in space characters).
IgnoreCase Search while ignoring the case (uppercase/lowercase characters) or the accented characters.

No option is selected by default: the search is sensitive to the case and it is performed on incomplete words.

Remarks

As long as this function is not called with an empty string ("") to stop the highlighting, all new calls will add an additional highlighting.
