[Visual Basic]

Params		  
Name Description
startIndex The start index for the selection as related to the string returned by the GetText method.
length The length for the selection as related to the string returned by the GetText method.
Return Returns a list of find matches encompassing the selected text.

 

    

Notes		  

Select a range of text in the document. If GetText has not been called previously then an exception will be raised.

This function is purposely designed to be similar to the String.Substring function. The concept is that you can use the text provided via the GetText method to identify pieces of text you are interested in. Then using the offset and length of the pieces you can select the actual text in the document.

The selection specifies the precise set of text fragments in the document. Each fragment has an area, some text and relates back to a text drawing operation within the content stream of the page. Applying the Group function to these fragments can group connected fragments into connected parts.

 

    

Example		  

See the Group function.
