Example
This example uses the Command function to get the command line arguments in a function that returns them in a Variant containing an array. Available in Microsoft Access, but not in other Microsoft Office applications.
Function GetCommandLine(Optional MaxArgs)
'Declare variables.
Dim C, CmdLine, CmdLnLen, InArg, I, NumArgs
'See if MaxArgs was provided.
If IsMissing(MaxArgs) Then MaxArgs = 10
'Make array of the correct size.
ReDim ArgArray(MaxArgs)
NumArgs = 0: InArg = False
'Get command line arguments.
CmdLine = Command()
CmdLnLen = Len(CmdLine)
'Go thru command line one character
'at a time.
For I = 1 To CmdLnLen
C = Mid(CmdLine, I, 1)
'Test for space or tab.
If (C <> " " And C <> vbTab) Then
'Neither space nor tab.
'Test if already in argument.
If Not InArg Then
'New argument begins.
'Test for too many arguments.
If NumArgs = MaxArgs Then Exit For
NumArgs = NumArgs + 1
InArg = True
End If
'Concatenate character to current argument.
ArgArray(NumArgs) = ArgArray(NumArgs) & C
Else
'Found a space or tab.
'Set InArg flag to False.
InArg = False
End If
Next I
'Resize array just enough to hold arguments.
ReDim Preserve ArgArray(NumArgs)
'Return Array in Function name.
GetCommandLine = ArgArray()
End Function
