From 'run' Hello.exe "My String" passes String in program

Is it possible to pass a variable from the command line ('Run' in windows) just by opening it providing a parameter from the command line.

Example:

I have a VB EXE called 'Hello.exe'

using a Short-Cut or user types under 'run'

Hello.exe "My String"

The program receieves a String to use in code

What data types may you pass.

use the following string:
Shell "Hello.exe " & yourString
For example I use the following code to open a picture file in IExplorer:

Dim TaskID As Long
TaskID = Shell("C:\Program Files\Internet Explorer\iexplore.exe " & txtFoto.Value, vbNormalFocus)

Shell works fine, an alt. solution is using ShellExecute. Still uses Shell if fails but handles more types

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
