ParameterTypeDescription

Function resultStringLong name of the 4D executable file or application

Description

The Application file command returns the long name of the 4D executable file or application you are running.

On Windows

If, for example, you are running 4D located at \PROGRAMS\4D on the volume E, the command returns E:\PROGRAMS\4D\4D.EXE.

On Macintosh

If, for example, you are running 4D in the Programs folder on the disk Macintosh HD, the command returns Macintosh HD:Programs:4D.app.

Example

At startup on Windows, you need to check if a DLL Library is correctly located at the same level as the 4D executable file. In the On Startup database method of your application you can write:

   If (On Windows & (Application type#4D Server))
      If (Test path name (Long name to path name (Application file)+"XRAYCAPT.DLL")#Is a document)
         ` Display a dialog box explaining that the library XRAYCAPT.DLL
         ` is missing. Therefore, the X-ray capture capability will not be available.
      End if
   End if

Note: The project methods On Windows and Long name to path name are listed in the section System Documents.
