$CmdLine not working as espected. See details.

[erm3nda]

I have a very strange problem, maybe related to some other i have.

$CmdLine is not working as espected. 
I know, $CmdLine[0] is a counter, then [1] is the 1st param passed, and $CmdLine[0] will be 2.

Create a new au3 file and call it program as example.

Put that: 
 

#include <IE.au3> 
#include <msgboxConstants.au3>

; Definitions

If $cmdLine[0] >= 2 Then
    msgbox(4096, "param1", $CmdLine[1])
EndIf

If $cmdLine[0] >= 3 Then
    msgbox(4096, "param2", $CmdLine[2])
EndIf

If $cmdLine[0] >= 4 Then
    msgbox(4096, "param3", $CmdLine[3]) ; THIS line is not working...
EndIf

msgbox(4096, "BAD", $CmdLine[3] & @CRLF & @CRLF & "I am the 3rd param on $cmdLine[3]")
msgbox(4096, "RAW", "Full content of $CmdLineRaw:" & @CRLF & @CRLF & $CmdLineRaw)

Compile to exe, then run from command line or bat: 

start program "1" "2" "3"

The expected result is 3 message boxes with 1, 2 and finally 3. The Third never comes, but the value is in, as you can see on BAD messagebox and RAW too.

I think the $CmdLine is a basic feature... too basic to fail at this stage.
Can anyone test to know if is a fail of me?

Oh! attached files. Just unzip, see, compile and tryout. A compiled copy is attached too.

Thank you.

Have you checked the value of $cmdline[0] when running it with the example with 3 parameters?

[erm3nda]

Sure...

Add then see: 

msgbox(4096, "RAW", "Counter of $CmdLine[0]:" & @CRLF & @CRLF & $CmdLine[0])

Result = 3, with is correct.

Also add:

#include <array.au3>

 and at bottom : 

_arrayDisplay($CmdLine);

Shoud display 4 element array, wich is the desired result with the correct values.

[Geir1983]

So if the value of $CmdLine[0] is "3" why do you expect something to happen in your last IF test? You are testing if its 4 or higher?

IF $cmdLine[0] > 0 then 
    For $idx=1 to $cmdLine[0] 
        msgbox(4096, "param"&$idx, $CmdLine[$idx])
    Next
EndIf

Sure...

Add then see: 

msgbox(4096, "RAW", "Counter of $CmdLine[0]:" & @CRLF & @CRLF & $CmdLine[0])

Result = 3, with is correct.

Also add:

#include <array.au3>

 and at bottom : 

_arrayDisplay($CmdLine);

Shoud display 4 element array, wich is the desired result with the correct values.

So that means that your tests are wrong and should be:

; Definitions

If $cmdLine[0] >= 1 Then
    msgbox(4096, "param1", $CmdLine[1])
EndIf
; etc....

... right?

Did u see the source i uploaded? I put the raw to test it's contents.

$CmdLine is empty except if you put content in there, so the first value of $CmdLine[0] is 2, never 1.
If a command line is passed, $CmdLine[0] will be 2, and $CmdLine[1] the first value. The >= is here to test. Using only = should work.

See the example i put, see how it works OK with cmdline1 and 2, then see how is not working.
The logic is not wrong i guess.

Test it please.

Did you even read the posts? We both pointed out what was wrong with your code and gave examples as how to fix it. Test the code below..

#include <IE.au3>
#include <msgboxConstants.au3>

; Definitions


If $cmdLine[0] >= 1 Then
    msgbox(4096, "param1", $CmdLine[1])
    ;Local $url = $CmdLine[1]
EndIf

If $cmdLine[0] >= 2 Then
    msgbox(4096, "param2", $CmdLine[2])
    ;Local $mode = $CmdLine[2]
EndIf

If $cmdLine[0] >= 3 Then
    msgbox(4096, "param3", $CmdLine[3])
    ;Local $output = $CmdLine[3]
EndIf

msgbox(4096, "BAD", $CmdLine[3] & @CRLF & @CRLF & "I am the 3rd param on $cmdLine[3]")
msgbox(4096, "RAW", "Full content of $CmdLineRaw:" & @CRLF & @CRLF & $CmdLineRaw)

Don't confuse $cmdLine and $cmdLineRaw. The latter has more parameters.

As the others have said, your mistake is starting at >= 2 instead of >= 1 and expecting a total count of 4 when it is only 3.

$CmdLine is not working as espected. 

I know, $CmdLine[0] is a counter, then [1] is the 1st param passed, and $CmdLine[0] will be 2.

 

Just do an _arraydisplay() on that. The array looks like:

[0] = 1 ; where you said it is 2, which is false

[1] = "the 1st param passed"

[Brobbl]

The expected result is 3 message boxes with 1, 2 and finally 3. The Third never comes, but the value is in, as you can see on BAD messagebox and RAW too.

 

 

You should try if it's really "1" and "2" that's given out by msgboxes, with your code it should be "2" and "3".

 

Also, you should could use this for better reading and scalability:

 

; Definitions

#cs################################################################
If $cmdLine[0] >= 2 Then
    msgbox(4096, "param1", 
$CmdLine[1])EndIf
 

If $cmdLine[0] >= 3 Then
    msgbox(4096, "param2", 
$CmdLine[2])EndIf
 

If $cmdLine[0] >= 4 Then
    msgbox(4096, "param3", $CmdLine[3]) ; THIS line is not working...
EndIf
#ce###############################################################

If isarray($CmdLine) Then
    For $i = 1 To $CmdLine[0]
        msgbox(4096, "param" & $i, $CmdLine[$i])
    Next
Else
    msgbox(4096, "No parameters were given")
Endif

No need to test on my side and I am fine you questioning what I stated.

Good luck.

msgbox(4096, "RAW", "Full content of $CmdLineRaw:" & @CRLF & @CRLF & $CmdLineRaw)

Oh my godness... I am totally wrong.

I don't know on what moment i've see $CmdLine[0] value as 2 using 1 param.

Thank you for your patience and sorry for inconveniences.
