66 Get Windows to perform OPERATION on DOCUMENT.
|
|
|
67 This is a wrapper around the ShellExecute system function, which
|
|
|
68 invokes the application registered to handle OPERATION for DOCUMENT.
|
|
|
69 OPERATION is typically \"open\", \"print\" or \"explore\" (but can be
|
|
|
70 nil for the default action), and DOCUMENT is typically the name of a
|
|
|
71 document file or URL, but can also be a program executable to run or
|
|
|
72 a directory to open in the Windows Explorer.
|
|
|
73
|
|
|
74 If DOCUMENT is a program executable, PARAMETERS can be a string
|
|
|
75 containing command line parameters, but otherwise should be nil.
|
|
|
76
|
|
|
77 SHOW-FLAG can be used to control whether the invoked application is hidden
|
|
|
78 or minimized. If SHOW-FLAG is nil, the application is displayed normally,
|
|
|
79 otherwise it is an integer representing a ShowWindow flag:
|
|
|
80
|
|
|
81 0 - start hidden
|
|
|
82 1 - start normally
|
|
|
83 3 - start maximized
|
|
|
84 6 - start minimized
