Environment Variables And Run Command

[JSchmitt]

Hello,

I´m reading values from an INI File.

I read the value e.g. $var as %WINDIR%\System32\notepad.exe.

I can log this variable to a file correctly.

If I try to make the following ...

Run ($var)

I will get an error: Unable to execute the external program.

This is just an example ... i would like to call another program defined in an INI File using environment variables!

Does anyone has an idea.

Thx in advance.

try :

Run(@comspec & " /c " & $var,"",@SW_HIDE)

Or:

Opt("ExpandEnvStrings", 1)
Run ($var)

Hello,

I have the OPT set and I tried your advice with no improvement.

I can call %TEMP% Variables set to Variables like:

$Execute = %Temp%\Hello.exe

but I can´t RUN a Command including variables read from an INI File!?

May be if you post your script or part of your script and example of what the ini file look like. I'm sure somebody will be able to help you.

$Path = IniRead($ConfigFile, "Settings", "Path", "%WINDIR%\SYSTEM32")

Hello,

I tried it on windows xp german and windows 2003 english with autoit3.exe version

3.1.1.0 downloaded yesterday and it won´t work !?

Can anyone else test the script and report the result.

With OS Version and AutoIT3 Version.

Thanx

Jochen

Your test is confirmed as an issue with AutoIt v3.1.1 release.

AutoIt v3.1.1 will only expand literal Environmental Strings.

e.g.

MsgBox(0, '3.1.1', '%WINDIR%')

AutoIt Beta had changes made to convert Environmental Strings within a variable also.

MsgBox(0, 'Beta', '%WINDIR%')

$Var = %WINDIR%
MsgBox(0, 'Beta', $Var)

Your issue was mentioned back in time here.

If you want to use the option of ExpandEnvStrings, I would recommend to use the beta here.

Edit:

The last code shows as literal as well, but consider it as an INIRead or RegRead into a variable instead which would not be a literal string within the script itself. The later will only work correctly in the beta.
