Function Reference
Page 269 of 818
The parameter DefDir defines a default directory in which the file should be searched. The
parameter Param defines an optional parameter string which can be passed to the application. This
parameter should be omitted if the FileName designates a document. The parameters DefDir and
Param are both optional, they can be NULL. See also ShellExecute() of your Windows API reference
for further information.
The last parameter NewWindow specifies whether the file should be opened in a new window or not.
This parameter is ignored if the file is not a PDF file.
