Formless VB exe that accepts command line args

[gpresto]

How do you create a vb program that needs no form and this program would be executed from the command line and accept command line arguments? Thanks

gpreston,

The following code will return an array of command line arguments. If you remove all the forms from you project, and add a module, Create a Sub Main procedure the insert

Sub Main

cmdArgs() = GetCommandLine(1)

Some code depending on what the command line arguments are

End Sub


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
