GetSelText

Syntax:

LBOOL psrGetSelText(

const PPDF* IPDF,

// PDF instance pointer

struct TTextSelection* SelText, // Required. Structure filled with

// data by FindText().

UI16** Text,

// Address of UI16* variable

UI32* TextLen)

// Address of UI32 variable

The function retrieves the text and text length of the current selection or found text.

This function is mainly a helper function for programming languages which do not support

pointers like VB 6, VB .Net, C#, and so on. However, the function is also useful if FindText() was

called with the search type stMatchAlways. In this case, and only in this case, it is not known

which text FindText() has found.

In C/C++, or Delphi you can access the text directly as follows:

UI16* text

= selText->TextOP->Text->UniText;

UI32 textLen = selText->TextOP->Text->UniTextLength;

Return values:

If the function succeeds the return value is 1. If the function fails the return value is 0.
