Environment variable expansion problem.

[micor]

When getting values containing environment variables from the registry, you may get the %var% text.

Sure, I can replace the % and do a EnvGet to get the "real" value of it.

But what if the returned value is say: %SystemRoot%\Temp

It there a more simple way to get it to say: C:\Windows\Temp than using StringMid and replacing % + EnvGet.

And finally, yes I am aware of the macros @WindowsDir, @SystemDir and @TempDir. They are all very nice, but do not provide the solution to my problem...

-----some examples-------

The first example will result in %SystemRoot%.

$test = regread("HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment","windir")

msgbox(0,"Test",$test)

The second example will result in %SystemRoot%\TEMP on most machines.

$test = regread("HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment","Temp")

msgbox(0,"Test",$test)

I gotta be the biggest nutcase ever for trying something this stupid...

Only literal strings get expanded so that wouldn't work.

I didn't know that. (I had problems before, but they're solved now.)

Can you make it that you can read env. variables using string variables?
