AP ShellExecute is a 4D Pack command that allows you to launch an application or open a document from with a 4D Database. It can be used for almost any file system purpose. You are allowed to have spaces in the path and file name. This is a common misconception! You do not need to 'escape' (by using a double \ on Windows or quotes "" on OS X) the path for it to be recognized properly.
An example would be to open a Microsoft Word document from within 4th Dimension.
On Mac OS X the following commands would work:
Using HFS path notation:
$err:=AP ShellExecute ("Production:Users:slack:test.doc")
Using POSIX path notation:
$err:=AP ShellExecute ("/Users/slack/test2.doc")
$err:=AP ShellExecute ("/Users/slack/test jason.doc")
$err:=AP ShellExecute ("/Users/slack/test documents/test jason.doc")
$err:=AP ShellExecute ("/Users/slack/test documents/test jason document.doc")
Each one of these examples illustrates a different example call using both spaces in the file name and directory names.
On Windows the following commands would work:
$err:=AP ShellExecute ("C:\Test.doc")
Windows also has an additional parameter to allow a specific document, website or really any valid path to the application you are requesting be opened.
This example would display the contents of the Music directory in Windows Explorer:
$err:=AP ShellExecute ("C:\WINDOWS\explorer.exe";0;"C:\Music")
If you do indeed receive a -43 (File Not Found) error, make sure to check the path to the file you are requesting.
