how to pass a parameter to a software before running

hi experts,
i want to automatically run a software from windows registry and must pass a parameter to it,
eg,
"c:\software\chema.exe /windowsreg"

i want the sofware to take the variable windowsreg so it can distinguish who initialized the software .

thank u in advance,

Your question can be interpreted several ways.

To run your program automatically, add the a key under
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Run

Name the key chema
and for the value add c:\software\chema.exe /windowsreg

The program will now run every time the pc is started.

If, however, your question is how can your program read the value "windowreg", then in your start up form or module, check Command$:

If Command$ = "windowreg" then
  Do something
else
   Do Something different
end if

have you tried:

Private Sub Command1_Click()
Shell "command.com /c c:\software\chema.exe /windowsreg"
End Sub

You can do it also by using ShellExecute API as below:

Private Declare Function ShellExecute Lib "shell32" _
    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
   
i = ShellExecute(Hwnd, "Open", "c:\software\chema.exe", "/windowsreg", 0&, 1)
