passing a variable into the exe

Recommended Posts


I don't know what to call what I want to do. From Command line I'd like to enter

C:SomeDirectory>MyProgram.exe MyVariable
So that MyVariable is taken into MyProgram.exe for processing in some way. What is that called, and how do I do it.

The help file is your friend:

Command Line Parameters

The special array $CmdLine is initialized with the command line parameters passed in to your AutoIt script. Note the scriptname is not classed as a parameter; get this information with @ScriptName instead. A parameter that contains spaces must be surrounded by "double quotes". Compiled scripts accept command line parameters in the same way.

$CmdLine[0] is number of parameters

$CmdLine[1] is param 1 (after the script name)

$CmdLine[2] is param 2 etc


$CmdLine[$CmdLine[0]] is one way to get the last parameter...

So if your script is run like this:

AutoIt3.exe myscript.au3 param1 "this is another param"

$CmdLine[0] equals... 2

$CmdLine[1] equals... param1

$CmdLine[2] equals... this is another param

@ScriptName equals... myscript.au3

In addition to $CmdLine there is a variable called $CmdLineRaw that contains the entire command line unsplit, so for the above example:

$CmdLineRaw equals... myscript.au3 param1 "this is another param"

If the script was compiled it would have been run like this:

myscript.exe param1 "this is another param"

$CmdLineRaw equals... param1 "this is another param"

Note that $CmdLineRaw just return the parameters.

Note : only 63 parameters can be return by $CmdLine[...], but $CmdLineRaw will always returns the entire command line.

[u]Helpful tips:[/u]If you want better answers to your questions, take the time to reproduce your issue in a small "stand alone" example script whenever possible. Also, make sure you tell us 1) what you tried, 2) what you expected to happen, and 3) what happened instead.[u]Useful links:[/u]BrettF's update to LxP's "How to AutoIt" pdfValuater's Autoit 1-2-3 Download page for the latest versions of Autoit and SciTE[quote]<glyph> For example - if you came in here asking "how do I use a jackhammer" we might ask "why do you need to use a jackhammer"<glyph> If the answer to the latter question is "to knock my grandmother's head off to let out the evil spirits that gave her cancer", then maybe the problem is actually unrelated to jackhammers[/quote]
