Windows PDF view helper
|
|
Author: Joost Verburg
|
|
|
|
This will be installed as pdfview.exe.
|
|
|
|
The application will launch the default PDF viewer to display the PDF file,
|
|
but works around the file locking problems of Adobe Reader.
|
|
|
|
Source code of pdfopen/pdfclose is available at:
|
|
http://magic.aladdin.cs.cmu.edu/2005/07/15/pdfopen-and-pdfclose/
