Better Shell Function

I need to be able to shell and application, file shortcut etc. from my application. The RUN command on the START menu can do this, so I figure there must be a suitable API call. I have found lots of them, but they all do slightly different things. I need to be able to shell a file as if I had just double clicked on it. Can someone show me some code to do this???

This is a good answer, but there are a couple of problems. I had actually already written code to do this. Anyway, this code cannot shell .lnk files (shortcuts). The other problem is that I need to be able to open a file using it's default action. E.g., if I make the filename a .wav file, I will want the function to Play it, not Open it, but I don't want my program to have to work out which action to perform. Maybe there is a constant to do this. I basically want something that will behave in the same way as the Run command on the Start menu.

Option Explicit

Put this in the General: Declarations section of your main module:

Private Declare Function GetDesktopWindow Lib "user32" () As Long
Private Declare Function ShellExecute Lib "shell32.dll" _
    Alias "ShellExecuteA" _
   (ByVal hwnd As Long, ByVal lpOperation As String, _
    ByVal lpFile As String, ByVal lpParameters As String, _
    ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

Private Const SW_SHOWNORMAL As Long = 1
Private Const SW_SHOWMAXIMIZED As Long = 3
Private Const SW_SHOWDEFAULT As Long = 10

Then put this in the subroutine where you want to open a file with the default associated program using the default action, and working on .lnk files:

Dim RetVal As Long, hWndDesk As Long
hWndDesk = GetDesktopWindow()
RetVal = ShellExecute(hWndDesk, vbNullString, "C:\WHATEVER.TXT", vbNullString, "C:\", SW_SHOWNORMAL)

Obviously, replace C:\WHATEVER.TXT with the filename of the file you want to open/play/whatever.

Sorry, but I actually got your previous answer to work. I had to play around with a few things. Anyway, sorry that I rejected your answer. Also, I have an identical question posted (something went wrong when I submited it) so if you answer that as well, you can have both lots of points. The question number is Q.10093842
