13562 | This is a wrapper around the ShellExecute system function, which | |
13563 | invokes the application registered to handle OPERATION for DOCUMENT. | |
13564 | OPERATION is typically \"open\", \"print\" or \"explore\" (but can be | |
13565 | nil for the default action), and DOCUMENT is typically the name of a | |
13566 | document file or URL, but can also be a program executable to run or | |
13567 | a directory to open in the Windows Explorer. | |
13568 | ||
13569 | If DOCUMENT is a program executable, PARAMETERS can be a string | |
13570 | containing command line parameters, but otherwise should be nil. | |
13571 | ||
13572 | SHOW-FLAG can be used to control whether the invoked application is hidden | |
13573 | or minimized. If SHOW-FLAG is nil, the application is displayed normally, | |
13574 | otherwise it is an integer representing a ShowWindow flag: | |
13575 | ||
13576 | 0 - start hidden | |
13577 | 1 - start normally | |
13578 | 3 - start maximized | |
