$CmdLine - Command Line

[davezub]

I've only been using AutoIt for two days and it is a wonderful product. I use Winbatch but AutoIt is quicly winning my heart and mind.

I'm writing a utility that takes 4 commandline parms, however, two are optional. The problem I'm having is testing to see if a commandline is empty/not exist.

I test to see if I have a least two commandline options:

If $CmdLine[0] < 2 .........

However I can't test $CmdLine[3]

If $CmdLine[3] = "".......

Array variable has incorrect number of subscripts or subscript dimension range exceeded.:

I realize that $CmdLine is a constant but can't think of a way to test it.

Program "CLOption 1 Req" "CLOption 2 Req" "CLOption 3 Opt" "CLOption 4 Opt"

Thanks.....

Here you go:

If NOT $CmdLine[0] Then
  ;No parameters have been specified
ElseIf $CmdLine[0] = 2 Then
  ;Two parameters have been specified
ElseIf $CmdLine[0] > 2 Then
  ;More than two parameters have been specified
   If $CmdLine[3] = "" Then
     ;Peform action(s) here...
   EndIf
EndIf

I use:

For $i = 1 To $CmdLine[0]
    Select
        Case $CmdLine[$i] = "-config"
            $bRunConfig = 1
        Case $CmdLine[$i] = "-runonce"
            $bRunOnce   = 1
    EndSelect
Next

That way it goes through all the arguments and sets variables and such if the commands are given.

You could tweek this to check arguments 3+ by changing:

For $i=3 To $CmdLine[0]

Thanks Guys,

What's cool about scripting is that there are some many different ways to do something. The program uses variable command line options (except for the last one).

wrapper /1=""ProgramName"" /2=""path\Exe"" /3=""commandline"" /4=CAPM"

Not the best hunk of code that I ever wrote but it seems to work. Thanks for sparking my brain and the examples.

;Checks if the /3 is there if not set it to "" if you use $CmdLine[0] in runwait and is empty causes errors

If NOT StringInStr ($CmdlineRaw, "/3") Then
    $CommandLine = ""
ElseIf StringInStr ($CmdlineRaw, "/3") Then
    $CommandLine = StringReplace($CmdLine[3],"/3=", "")
EndIf

;Check for required commandlines /1 and /2
If NOT StringInStr ($CmdlineRaw, "/1=") Then
  MsgBox(4096,"Error", "Commandline Incorrect - wrapper  /1=""ProgramName"" /2=""path\Exe"" /3=""commandline"" /4=CAPM",10)
  Exit (100)
EndIf
