run wait description not clear

[russell]

So trying to unzip a readme i used this in dos

cd C:\Program Files\7-Zip\
7z.exe e -y readme2.7z

Everything works fine. Then i use this code

$val = RunWait (@ComSpec & " /c " &  "C:\PROGRA~1\7-Zip\7z.exe e -y readme2.7z"); & $hDownload)
 
@SW_MAXIMIZE)
MsgBox(0, "Program returned with exit code:", $val,5)

I get a return 2. So i go back to help and it says

To run DOS commands, try RunWait(@ComSpec & " /c " & "commandName") ; don't forget " " before "/c"

???? use " " befor "/c"? ..........what? the example doesn't show that it is using

RunWait(@ComSpec & " " " /c " & "commandName")

it is referring to the "s around /c? , "s around @ComSpec? <--makes no sense. Either it is just poorly worded or its so simple im missing it

It is telling you that you need to include a space before the /c after @comspec. There's no way to indicate that you need a space there without highlighting it by the quotes. So the command would start like RunWait(@Comspec & " /c "

Ok that makes more sense. Then why would the code return 2 if the same code/command works in dos?

[russell]

I think this would be more reasonable, but that just me

To run DOS commands, try RunWait(@ComSpec & " /c " & "commandName") ; don't forget to use a space before "/c" to separate the & from the "/c"

When you call RunWait using @ComSpec, it runs "cmd.exe" and instructs it to launch another program (in this case, 7z). So the return value is the one from CMD, not the one from 7Z.

Have you tried to run

CMD /c C:\PROGRA~1\7-Zip\7z.exe e -y readme2.7z

from the command line?

I'm making something similar, but I use RunWait directly, like

RunWait($Command & " " & $Parameters,"",@SW_HIDE)

It works... more or less. Having other problems in other post, but it does the work.

Hope to help.
